Title: Compound semiconductor device
Inventor: NAKAGAWA YASUHITO
IPC: H01L21/24
Filed: 1989-09-29
Abstract: PURPOSE:To inhibit sufficiently a short-tunnel phenomenon to eliminate a change in a gate threshold voltage and to contrive the improvement of the current cut-off characteristics of the title device by a method wherein an opposite-conductivity-type low-concentration impurity-containing layer to encircle a one-conductivity-type low-concentration impurity- containing layer is arranged and an opposite-conductivity-type high-concentration impurity- containing layer to encircle one-conductivity-type high-concentration impurity-containing layers is arranged to constitute the device. CONSTITUTION:A one-conductivity-type low-concentration impurity-containing layer 3, which acts as an active layer of a FET, and a pair of one-conductivity-type high-concentration impurity-containing layers 7, which are positioned on both sides of this layer 3 and respectively act as a source and a drain of the FET, are provided in the surface layer of a compound semiconductor substrate. An opposite-conductivity-type low-concentration impurity-containing layer to encircle the layer 3 and an opposite-conductivity-type high-concentration impurity- containing layer to encircle the layers 7 are arranged in this substrate. Thereby, the thickness of a channel, through which a current is made to flow, is inhibited from becoming thick by the opposite-conductivity-type low-concentration impurity-containing layer without augmenting a parasitic capacitance, which is generated in the p-n junction part between the layer 3 and the opposite-conductivity-type low-concentration impurity-containing layer, and a substrate leakage current, which is made to flow between a pair of the layers 7 arranged in close contact to each other, can be inhibited by the opposite conductivity type low-concentration impurity-containing layer.

Title: Dispersing agent for excavation slurry and excavation slurry using the same
Inventor: SUMIDA MITSUTERU
IPC: E21D9/13
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a dispersing agent which gives slurry having wall-making property from a granule ingredient alone of excavated soil without requiring a slurry-making material by composing it of a poly(meth)acrylate salt (copolymer) and sodium carbonate. SOLUTION: Preferably, a poly(meth)acrylate salt (copolymer) has a wt. average mol.wt. of 10,000-14,000 and is a monovalent salt (e.g. a sodium salt). A dispersing agent for excavation slurry composed of the poly(meth)acrylate salt (copolymer) and sodium carbonate and soil constituted of a granule ingredient, preferably not larger than 10 μm are compounded to form excavation slurry. Desirably, the amounts of dispersing agent added to the excavation slurry are 0.2-1% for sodium polyarylate and 0.05-2% for sodium carbonate to produce a marked synergetic effect owing to joint use of the two components. This excavation slurry can maintain low viscosity owing to the high dispersing function of the dispersing agent even if the gravity of the slurry is high, resulting in improvement of excavation efficiency, transportation efficiency and soil-sand separation efficiency.

Title: Compressor control device for air conditioning equipment
Inventor: NAKAZAWA YUKIO
IPC: F02B3/06
Filed: 1984-12-06
Abstract: PURPOSE:To enable a diesel car and others which produce no negative pressure in an intake manifold, to be controlled in a device where the discharge temperature of an evaporator and a compressor under the accelerating condition are controlled by configurating the device in such a manner that the accelerating condition is determined by the differential coefficient of the engine speed. CONSTITUTION:The number of revolution of an engine is detected by an engine speed sensor 10, and the stepping depth of an accelerating pedal is detected by an accelerating switch 13. The both detected signals are inputted into a control amplifier 14 where (14) the number of revolution of the engine 10 is differentiated allowing change in differential coefficient to be compared one by one. This allows the amplifier 14 to determine whether a car is running at a stationary speed or is accelerating based on the amount of the above said change. Simultaneously, the car is determined by the acceleration switch 13 whether it is accelerating or not. If the car is found to be accelerating, an operation rate control signal is outputted allowing the compressor operating temperature to be set higher through a thermo-amplifier 3. Then, this effects an ON-OFF control of a relay. This configuration enables even a car which produces no negative pressure in an intake manifold to be controlled.
