Title: Field-effect semiconductor device
Inventor: HAGINO HIROYASU
IPC: H01L29/78
Filed: 1987-09-24
Abstract: PURPOSE:To reduce ON resistance, by forming a second conductivity type epitaxial layer of high resistance on a second conductivity type substrate of low resistance using phosphorus and the like as impurity, constituting a gentle concentration distribution of impurity between the substrate and the epitaxial layer, and making the thickness of the epitaxial layer sufficiently thin. CONSTITUTION:For a second conductivity type substrate 11 of low resistance, phosphorus as impurity, which largely protrudes in a second conductivity type epitaxial layer 22 of high resistance, is used. The substrate 11 is made to largely protrude in the epitaxial layer 22, and a protruding part 12 is formed to constitute a gentle impurity concentration distribution between the substrate 11 and the epitaxial layer 22. Breakdown voltage is maintained by the gradient of impurity concentration distribution, and the thickness of the epitaxial layer 22 is sufficiently thinned. Thus resistance REpi is reduced, so that the ON resistance Ron can be sufficiently reduced.

Title: Shaft for roll paper holder
Inventor: URASAKI TSUNEKICHI
IPC: A47K10/36
Filed: 1987-09-25
Abstract: PURPOSE: To easily pull out paper by interposing a resistant spring between an inner ring and an outer ring, attaching a rotation stopper on a main shaft, fitting a rotation pad to the inner ring, inserting the inner end of a spring into a groove hole on the main shaft and hooking its outer end on the foot part of the inner ring. CONSTITUTION: When the rolled paper is pulled out and an outer ring 1 is rotated, an inner ring 2 is rotated in the same direction by a resistant spring 12 as well. The inner ring 2 rotated in respect to a main shaft 3 is rotated until a rotation pad 10 is abutted to a rotation stopper 9 while pulling a spring 11, and the rotation is stopped. After the inner ring 2 is stopped, however, the outer ring 1 is slipped and rotated on the inner ring 2, and the rolled paper is rotated as pulled out. In this case, since the resistant spring 12 is set stronger than the backward spring 11, it does not slip without fail until the rotation pad 10 is abutted to the rotation stopper 9. When the paper is cut off, the rolled paper is made to generate rotation reverse to pull-out rotation by the operation of the backward spring, and the rear side of the rotation pad 10 is abutted to the rotation stopper 9 and stopped. The cut-off edge is reversely rotated, stopped and drooped because of gravity.

Title: Signal transmission device
Inventor: OURA MIKIO
IPC: G08C25/00
Filed: 1989-09-19
Abstract: PURPOSE:To output an output signal of prescribed accuracy even if a microprocessor becomes operation abnormality by some cause by switching an output signal of a D/A converter for converting an arithmetic output from the microprocessor to an analog signal to a signal from a converting amplifier and outputting it. CONSTITUTION:When an operation of a microprocessor 5 is normal, a switch 9 selects an output from this microprocessor 5. In this state, a converting amplifier 3 inputs a signal 2 from a pre-amplifier, executes an adjustment of a zero point and a span value and always outputs its signal to the switch. When a monitoring means 8 detects abnormality of an operation of the microprocessor 5, the switch 9 selects an output signal of the converting amplifier 3, and outputs a signal generated therefrom to a voltage/current converting part 10 through the switch 9. In such a way, even if the microprocessor 5 becomes operation abnormality, an output signal having prescribed accuracy can be outputted continuously.

Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To avoid increasing the leak current by irradiating As or As oxide near an exposed semiconductor with light in a F-contg. gas atmosphere to react until As fluorides evaporates. SOLUTION: On one main surface of a semi-insulative GaAs substrate 101 an insulation film is formed, and p- and n-type semiconductor layers 104, 105 are formed. A gate electrode metal 106 is deposited and processed to form gate electrodes 161, using a patterned resist 107 as a mask. As and As oxides near an n-type semiconductor layer 105 are removed by in adiation with pulse light in an F2 gas atmosphere.

IPC: H01M8/02
Filed: 1986-10-15
Abstract: PURPOSE:To make a cooling plate thin and lightweight by embedding cooling pipes in highly flexible expanded graphite and sandwiching between high anticorrosion glass carbon plates. CONSTITUTION:Cooling pipes 42 are embedded under compression in expanded graphite 50 obtained by treating flake graphite having high crystallinity, then heating at high temperature, and sandwiched between high anticorrosion glassy carbon plates 51 to obtain a cooling plate 30. The surrounding 55 is formed with fluorine resincontaining expanded graphite to increase the shape stability.

In this cooling plate, when the cooling pipe 42 having a diameter of 3mm is used, the thickness of the cooling plate becomes about 5mm. This thickness is almost half that of a cooling plate using normal graphite plate.
