PURPOSE:To perform the maintenance work efficiently and easily by supporting the lower section of a tower for windmill fixed with a rotor at the upper section foldably while constructing the tower switchably between the rising position and the lowering position. CONSTITUTION:The lower section of a tower 1 is coupled foldably through a hinge 7 to a base 1a so as to enable alternate switching of the...

PURPOSE:To move a vehicle to run in a desired direction without converting the direction of the vehicle, by making the wheels other than the driving wheels into caster wheels, giving a rotation drive to the driving wheels while fixing the driving wheels in a desired direction, and making the caster wheels follow the direction of the driving wheels consequently. CONSTITUTION:By operating a primover...

PURPOSE:To cut an object to be cut having a polymerizable org. adhesive layer without hindrance by cutting said object by laser light and at the same time by polymerizing the exposed adhesive agent on the cut face and making the same non-adhesive. CONSTITUTION:The adhesive agent exposed on the cut surface of an object to be cut (for example, adhesive sheet) having a adhesive layer consisting mainl...

PURPOSE:To eliminate residual magnetism and prevent the gear from squeaking due to dragging or another in such a way that when the speed change gear is at the neutral position, reverse magnetic current is flowed, in an electromagnetic clutch for vehicle to transmit its power. CONSTITUTION:When a speed change gear comes to its neutral position, a neutral switch 50 is closed, low level signal (L) co...

PURPOSE:To avoid a gear noise at the time of gear shifting, by causing an inversely exciting current to flow through the coil of a clutch to remove the torque of the clutch itself due to residual magnetism when the speed of a vehicle is not higher than a set level and its transmission is in neutral position. CONSTITUTION:When the speed of a vehicle is not higher than a set level and either gears a...

A sheet supply receptacle is disclosed which permits the operator to prepare many reams of sheets of paper for use in a very high speed copier/duplicator. The receptacle, when pre-loaded with reams of paper, is adapted to be applied to the sheet supply apparatus of the copier/duplicator, to deposit the reams on the sheet supply tray or elevator for the copier/ duplicator in proper sheet feeding re...

Disclosed is a method for stopping and starting a reactor equipped with a heat exchanger, a catalyst settler, a catalyst filter and the like, which method is suitable for use in a process for the preparation of acrylamide by reacting acrylonitrile with water in the presence of a metallic copper-based catalyst used as a suspended bed. According to this method, various undesired phenomena which may ...

A protective composition which comprises at least one aliphatic polyisocyanate, at least one aromatic polyisocyanate and a solvent.

An electrosurgical meniscal cutting device including an elongated probe adapted for insertion into an incision and first and second electrode supports carried by the probe. The electrode supports are movable relative to each other to vary the spacing between them. A variable length electrode extends between the electrode supports so that the length of the electrode can be varied by varying the spa...

A golfing apparatus which has the combined function of an umbrella and a backstop for a low trajectory golf ball. In the umbrella configuration, the apparatus operates as a conventional umbrella and may be repositioned from a closed to an open position where the canopy portion of the umbrella extends downwardly in a bowed configuration. The canopy may be inverted to another position in which the c...

A guidance system for an unmanned transporting vehicle which runs along a guide track. The guide track is composed of a belt-shaped light reflective material and laid out on a floor or the like. The unmanned transporting vehicle has two rows of photodetectors longitudinally arranged thereon forwardly of the front wheel. Since the two rows of the photodetectors are spaced apart from each other with...

A process for the treatment of the surface of a transparent sheet or film having antilacerative and self-healing properties and the product made thereby, wherein the sheet or film includes a thermosetting polyurethane material employed as an external layer on a laminated glass or laminated plastic sheet or a mixture thereof. The process involves depositing a solution, dispersion or emulsion of wax...

Polyisocyanurate foams are prepared by reacting together an organic polyisocyanate, a blowing agent, a trimerization catalyst, and a minor amount of a polyol mixture prepared by digesting polyalkylene terephthalate, particularly polyethylene terephthalate, with a polyol, especially a glycol. Laminates of such foams exhibit a high degree of fire resistance, low smoke evolution on combustion, low fo...

A data processing apparatus has a central processing unit. The CPU causes a memory to store for example input sales data in units of department sales and other items. When a power supply is turned off, a battery supplies back-up power supply voltage to the memory to retain the storage contents of the memory. When the output voltage from the battery is decreased to a value which disables back-up of...

Fault checking of slave devices. All the slave devices are polled periodically by a master control circuit and their reponse is noted. The master control circuit asserts a control signal for every other poll so as to cause the slave device to invert the bits in its response signal when the control signal is asserted. The non-inversion of the bits during the period of several polls is indicative of...

A safety binding (1) for downhill skiing comprising a toe connection means (5, 24) and a heel connection means (6) for cooperation with corresponding parts of a ski boot (3), in which the toe connection means comprising a rotatable roller (5) having a support web portion (16) and from the said web portion an upwardly diverging conical portion (17), which roller (5) and its shaft (12) are spring bi...

The subsurface position of a blowing well with respect to an adjacent relief well is determined by detecting at a plurality of axially and tangentially spaced locations in the relief well acoustic waves emanating from a subsurface location of the blowing well. The distance between the wells is calculated on the basis of the difference in times of arrival of the waves at said axially spaced locatio...
