PURPOSE:To prevent a vehicle speed from being fluctuated when a brake is excessively applied by configurating a device in such a way that an inlet port of a cylinder device, which is rendered effective to brake a vehicle upon exceeding of a flow rate from a pump which discharges the flow rate proportional to a reversing speed, is communicated with a discharge port of the pump by way of a stop valv...

PURPOSE:To prevent the temperature of a clutch from being increased so as to lengthen its duration by configurating a device in such a way that the temperature which is generated by a torque absorbed by a magnetic particle type electromagnetic clutch, is estimated so as to control the revolving speed of a slip based on the estimated temperature. CONSTITUTION:A device as referred to the title allow...

A process and apparatus are provided for making a bead wire and bead zone filler for a vehicle tire. The apparatus has a rotatable drum and deformable tubular member disposed on the drum. The external surface of the tubular member is adapted to receive a strip of elastomeric material to be shaped into the bead zone filler. The tubular member is changed from tubular to annular shape with a fluid un...

The grinding apparatus permits precision machining of a valve seat or a sealing surface, and includes a grinding spindle having a holding and guiding part extending into a finished workpiece bore with clearance. The holding and guiding part is smaller in diameter than the grinding spindle and includes a pin which carries on its free end a grinding tool. The other end of the pin passes into the gri...

A process for the treatment of a soft contact lens, to increase its resistance to the deposition thereon and diffusion and accumulation therein of substances which will promote its clouding and discoloration in use, and to improve its mechanical strength, includes treating a hydroxyl group-containing acrylic ester soft contact lens or replica with an organic acid anhydride for a sufficient period ...

PURPOSE:To carry out multiplication with high accuracy kept for operations of a multiplier by using a means to count the pulses of the shift clock and obtaining the number of shift clocks which are needed for arithmetic operation between vector data and a matrix. CONSTITUTION:A digit value memory 8 stores digit values showing the decimal point positions of matrix elements against a conversion matr...

A package for housing a microwave or RF microcircuit is disclosed. The package consists of a base (10) and a cover (12). The base (10) is constructed from a material that has the same thermal expansion coefficient as the microcircuit's substrate material. The base has an electrically conductive surface (14). The cover (12) is also electrically conductive. The cover (12) is adhered to the conductiv...

PURPOSE:To efficiently obtain pitch having a tensile strength, elastic modulus, etc., suitable for carbonaceous materials, particularly carbon fibers, by heat- treating petroleum based pitch after removing light oil under specific conditions in two stages. CONSTITUTION:Raw material pitch after removing light oil in petroleum based heavy oil is heat-treated under conditions of 450-550 deg.C, prefer...

A surface coil for use with magnetic resonance imaging apparatus comprises an electrically-insulating, flexible tube which is filled with a liquid mercury conductor.

A method and apparatus for tightening or loosening screw-type connections, in which the screw bolt is stimulated to oscillate longitudinally, the natural frequency of the bolt is measured and the excitation frequency is made to follow the changing natural frequency during the bolting process with a minimum, necessary excitation energy, so that the screw bolt attains a permanent state of resonance.

A method for forming a fracturable seal 30 between a plastics closure cap 20 and a plastic planar surface 27 around the neck of a container 12, wherein the cap is seated on the planar surface and a heated die 28, which surrounds the cap, is caused to be moved towards the planar surface and to melt both the plastics at the planar surface by contact therewith and the portion of the cap adjacent the ...

The invention relates to a method of impressing channels having a cross-sectional area of less than 1 mm2, notably less than 3000 mu m2, into the surface of an object, notably for the formation of damping channels of ink jet printer heads. The impression of channels having a small cross-sectional area can be performed with high precision by inserting a wire-shaped element (5) between the surfaces...

PURPOSE:To make it possible to more effectively use a battery driving apparatus by stepwise informing the voltage drop of a battery to an operator, by simultaneously changing the number of display symbols and ON-and-OFF frequency as the voltage of the battery changes. CONSTITUTION:A power source part 1 contains a battery and supplies power to an apparatus to be driven while a control part 2 contro...
