PURPOSE:To prevent a system control circuit from runaway by permitting the system control circuit to detect a drop in a battery voltage, stopping the execution of a system program at the time of the detection, storing the detected result in a detected result storage circuit and feeding back the storage contents to the system control circuit. CONSTITUTION:When a battery 1 is further consumed to dro...

PURPOSE:To make it possible to automatically produce meat buns not inferior to those made by hand, by forming a coat for enveloping ingredients into a recessed shape, thinly extending the sidewall part of the coat to sufficient thickness, filling the ingredients and squeezing the edge part of the coat into ribbed from. CONSTITUTION:An endless belt 9 with a perforated hole 12 is laid above blanking...

An apparatus for the evaluation of a flat test carrier for the analytical determination of components of a body fluid, has a measurement unit and a positioning means which positions and firmly holds a test carrier in a measurement position so that its test field is present in a definite position with regard to the measurement unit; for the evaluation of test carriers with a covering layer fixed in...

Oil emerging from a storage tank and containing all forms of pollution is placed in extensive surface contact with an underlying washing liquid having a greater specific gravity, on to which it diffuses, gives up to it material soluble therein and, in the absence turbulent flows causes solid particles to sink into it after which it rises up and makes room for newly-arriving contaminated oil. This ...

A packaging material for photosensitive materials for photographic purpose being light-shielding and having the following polyethylene polymer layer; (a) containing 40 to 99% by weight of a low-pressure linear low-density polythylene (L-LDPE) produced by copolymerization of ethylene and heptene-1 or octene-1 by a liquid phase method, the density of said polyethylene is in the range from 0.870 to 0...

A crosslinked polyvinyl chloride resin composition comprising: A: a polyvinyl chloride resin, B: at least one copolymer selected from the group consisting of ethylene/acrylic acid copolymers, ethylene/alkyl acrylate copolymers and ethylene/alkyl methacrylate copolymers, and C: a polyolefin resin and having a high expansion ratio, and a foam sheet prepared from the composition.

In the optical head, laser beams are converged by the objective lens and projected on the light-receiving surface of the optical disk. The diverged laser beam is reflected by the light-receiving surface, converged by the objective lens into parallel laser beams, and directed to the light shielding plate. Only the laser beam passing through the region spaced from the optical axis is picked up by th...

PFBC power plant for burning fuel, primarily coal, in a fluidized bed of particulate material, at a pressure exceeding the atmospheric pressure. The plant comprises a bed vessel (12) which is divided into a first section (14) and a second section (16) by a vertical partition (17) which reaches up to the upper wall of the bed vessel (12) so as to form two separate freeboards (86 and 46, respectivel...

Moldings are described which are composed of a silicic acid with a layer structure, or salts thereof with the general formula (H,M)2SiyO2y+1, or the corresponding hydrates, M representing lithium, sodium, potassium or ammonium and y being 1.7 to 24. They can be prepared for example by extruding pulverulent layer silicic acids, or salts thereof with the general formula (H,M)2SiyO2y+1, or the corres...

Polyester fiberfill having spiral crimp that is randomly-arranged and entangled in the form of fiberballs with binder fibers, preferably with a minimum of hairs extending from the surface of the fiberballs, so as to be air-transportable on account of the low cohesion between the balls. A process for making such fiberballs by repeatedly air-tumbling small tufts of such fiberfill/binder/blend agains...

PURPOSE:To reduce extension and contraction of a block copy due to change of humidity and to prevent bleeding and beading and the like by coating both sides of paper with polymer films and forming an ink-absorbing writing layer on the surface of the coating layer. CONSTITUTION:As the polymer coating layer, ones smaller in length change due to humidity variation are preferable, and polyethylene is ...
