Title: Semiconductor integrated circuit device
Inventor: SUMIYA MASANORI
IPC: H01L29/80
Filed: 1987-03-06
Abstract: PURPOSE:To inhibit a side gate effect, and to prevent the variation of element characteristics by forming a P conductivity type region between the constitutional elements of an IC shaped to a semi-insulating III-V compound semiconductor substrate and an ohmic electrode onto the region and setting the potential of the P conductivity type region at a value lower than the potential of the adjacent constitutional element. CONSTITUTION:In a semiconductor integrated circuit device consisting of a plurality of elements shaped to a semi-insulating III-V compound semiconductor substrate 40, a P conductivity type region 45 in depth deeper than at least mutually adjacent element regions is formed between these elements, and an electrode 46 being in ohmic-contact is shaped onto the P conductivity type region 45. The potential of the P conductivity type region 45 is controlled at a value lower than the potential of the adjacent element. Accordingly, the potential barrier of the P conductivity type region 45 can be kept at a sufficiently high value, thus inhibiting a side gate effect.

Filed: 1987-03-05
Abstract: PURPOSE:To simply each the danger of a laser beam leakage by providing a connection detecting means for allowing a laser beam driving circuit to stop its effective operation, when one end of an optical fiber is not connected to an fiber use connector of a printer control board. CONSTITUTION:An optical fiber use connector 40 is fixed to a prescribed position on a printer control board 28, and on this printer control board 8, an interlock switch 50 is also fixed in the vicinity of the connector 40.

Title: Brake releasing device for self-weight closing type shutter
Inventor: HOSAKA TAKAO
IPC: E06B9/80
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To improve maintainability by detecting whether a start signal inputted to a brake release means of a shutter closed by its own weight by a fire detection signal has reached the specified voltage, and informing to that effect. SOLUTION: A switch S of an interlock controller 15 is closed by a fire detection signal, and a battery power supply 16 and a brake releasing device 8 side circuit are connected to apply a current to a solenoid 13a so as to retreat a locking body 13. With the retreat of the locking body 13, a brake lever 10 is pushed to the right by the energizing force of a spring 12 to release a braking device and to close a shutter curtain by its own weight. A release rod 11 pushes a microswitch 14 to cut off current application to the solenoid 13a. In the case a start signal supplied to the solenoid 13a has not reached the specified voltage enough to retreat the locking body 13, it is so set as to light an informing lamp 21. The failure of an electric system can thereby be diagnosed easily.
Patent JP-H01227697-A (JP)
Title: Pulse motor driving circuit
Inventor: NAKAMURA NORIMASA
IPC: H02P8/00
Filed: 1988-03-04
Abstract: PURPOSE:To always maintain the torque of a motor constant controlling the motor driving current in response to the temperature change of the motor. CONSTITUTION:The temperature of a resistor 7 of a pulse motor 5 is raised by the heat generated from exciting coils 6a-6d, and the resistance value of the resistor 7 is thereby raised. A timer generator 3 increases a low level period of a common drive signal E on the basis of the time constant of the increased resistance value of the resistor 7 and the value of a capacitor 10. Thus, since the amount of a common current I1 is increased by the increased amount of the signal E, constant phase currents I1-I5 are always supplied to the coils 6a-6d of the motor 5, thereby maintaining the torque of the motor 5 constant.

Title: Spiral gasket
Inventor: ARIMORI KIYOSHI
IPC: F16J15/12
Filed: 1988-03-03
Abstract: PURPOSE:To improve balance performance by forming the inner and outer peripheral shaped parts of a filler held in spiral form into a filler having a basic member made of the inorganic material other than asbestos and forming an intermediate shaped part other than the both shaped parts from an expandable graphite filler and forming a wound part in one turn or more. CONSTITUTION:The inner peripheral shaped part 2C and outer peripheral shaped part 2A of a spiral filler are made of the inorganic filler having a basic material consisting of the inorganic material other than asbestos, and an intermediate shaped part 2B consists of an expandable graphite filler, and has a wound part in one turn or more. The volume content of the expandable graphite filler in a filler 2 is 50% or less, and the frictional coefficient between the inorganic filler and a metal band plate 1 is 0.25 or more. Therefore, the buckling of the inorganic filler itself due to the tightening is suppressed by the elasticity of the filler itself and the frictional coefficient. Further, since the expandable graphite filler is not exposed to the environment directly because of the inorganic filler, the oxidation of the expandable graphite at high temperature is prevented, and the high heat resistance and sealing performance can be secured.

Title: Integrating sphere type turbidimeter for continuous measurement
Inventor: SAITOU HIROSHI
IPC: G01N21/53
Filed: 1983-03-26
Abstract: PURPOSE:To take an accurate continuous mesurement of turbidity stably and easily by guiding light transmitted through a sample cell into an integrating sphere, and detecting separately the diffusion reflected light of totally transmitted light and the diffusion reflected light of scattered transmitted light and displaying the ratio of their outputs. CONSTITUTION:Parallel luminous flux projected by a light source 1 is made incident to the integrating sphere 3 through the sample cell 2 and an opening 4. Transmitted light except the scattered transmitted light enters a rotary sector 6 equipped with a diffusion reflecting part 9 and a gap part 10 through an opening 5, and light reflected by the reflection part 9 and scattered transmitted light are reflected repeatedly in the integrating sphere to enter a photodetector 8. The transmitted light incident to the gap part 10 of the rotary sector 6 through the opening 5 is absorbed by a trap 7 and only the scattering transmitted light is diffused and reflected repeatedly in the integrating sphere 3 to be mode incident to the photodetector 8. Both output signals from the photodetector 8 are separated by a changeover switch 22 and held by holding circuits 23 and 23, whose output ratio is calculated continuously and displayed on an indicator 21. Consequently, an accurate measurement of the turbid is taken stably and easily.

Title: Fuel/water feeder for internal combustion engine
Inventor: HAABAADO ENU DABURIYUU HANSEN
IPC: F02B47/02
Filed: 1985-03-14
Abstract: An internal combustion steam engine is operated with an alcohol-water fuel mixture vaporized prior to combustion by heated engine coolant that flows through a first heat exchanger (18). The first heat exchanger or vapor generator (18) uses the waste heat from the engine coolant to heat and vaporize the alcoholwater mixture. A second heat exchanger (60) using exhaust gases heats the combustion air before passage through the intake manifold (46). Complete vaporization of the alcohol fuel is accomplished to overcome the lower caloric power potential of alcohol as compared to gasoline and to insure complete and regular combustion.
