Title: Non-linear converter of integration type
Inventor: ABE JIYUNICHIROU
IPC: H03M1/58
Filed: 1979-02-27
Abstract: PURPOSE:To reduce the required number of stages of the precise resistors and to increase the degree of circuit integration, by selecting the variable reference voltage having opposite polarity as the input signal after the integration for a given time and integrating it through a single input resistor. CONSTITUTION:The input signal Vi is fed to the integrator IA through the input resistor Ri and integrated for a given time. The polarity of the output E1 is detected at the comparison circuit COMP, this detection signal determines the selective contact of the switch SW2, and the voltage of opposite polarity as the polarity of the voltage Vi is fed to the contact c until the output E1 returns to zero. When the voltage E1 is again zero, the circuit COMP detects it, and the output of the monostable multivibrator OS is given to the buffer memory circuit LAT. The circuit LAT responds to it, reads in the count value of the pulse counter COU and outputs the digital signal in linear operation of Vi at the output OUT. Further, the operation which sequentially and automatically performed is controlled with the counter COU.

Inventor: OOISHI KIYOHIKO
IPC: F01N3/02
Filed: 1983-02-16
Abstract: PURPOSE:To provide a trap regenerating device capable of performing sufficient combustion of fine exhaust gas particles by a method wherein a throttling of intake gas is performed in a high speed range of engine and either a secondary fuel injection or both of a secondary fuel injection and a throttling of intake is performed. CONSTITUTION:When a computer 9 judges that the engine is at a high speed range in reference to signals from a load sensor 17 and a rotation sensor 18, the instruction is transmitted to the load change-over valves 6 and 7 to close an intake throttle valve 3 until it shows a desired pressure of an intake pressure sensor 20. When the computer 9 judges that the engine is at a low or medium speed range, fuel is secondary injected into cylinders of intial exhaust stroke through the change-over valves under instruction for the computer to increase temperature in a trap 10 and to combust the exhaust fine particles. When a sensor 11 for exhaust gas temperature detects that a rate of increased temperature is insufficient in the trap 10, the computer 9 produces an instruction to close the intake throttle valve 3.

Title: Disk device
Inventor: KIMURA SHUICHI
IPC: G11B7/08
Filed: 1987-02-02
Abstract: PURPOSE:To surely count the number of reversed tracks by obtaining a continued output by using the timer circuit having the set time equiv. to a slightly longer time than the period of the data signal having the maximum period. CONSTITUTION:In the case of the traverse speed of an optical head 2 becoming faster, a speed detection output SSP exceeds a window voltage VWID, a switching circuit 13 is switched to a 13H side to sent out a high speed traverse detection signal SH to a traverse track counter circuit 6. The period of the traverse signal L2 included in a reproducing signal RF becomes in the same degrees as the period of a data signal DATA and the amplitude of the signal DATA is reduced. A timer circuit 22 is triggered once again prior to the completion of a set time after performing a reverse motion by the differential pulse K1 transmitted from a threshold circuit, so the output maintains an H level. Consequently one signal SH only is fed out while the head 2 transverses one recording track TR to perform a sure count.

Title: Vibration isolator
Inventor: SUZUKI SHINGO
IPC: F16F13/14
Filed: 1991-02-19
Abstract: PURPOSE:To improve the durability of a vibration isolator by giving a compressing force to an elastic body. CONSTITUTION:A pair of elastic bodies 14 provided with extending metal fittings 28 are cured and adhered to the inner circumferential surface of a middle cylinder 12. After curing, an inner cylinder 36 is disposed between the holding parts 32 of the extending metal fittings 28, the claw parts 34 of the extending metal fittings 28 are fitted to the grooves 38 of the inner cylinder 36. Since the outer diameter (dimension H) of the inner cylinder 36 is larger than the space (dimension G) between the holding parts 32, a compressing force is given to the elastic bodies 14. As the tensile stress acting on the elastic bodies 14 at the time of relatively moving the middle cylinder 12 and the inner cylinder 36 is thus eased by the compressing force, cracking of the elastic bodies 14 and peeling of the adhered part are prevented, and the durability of the vibration isolator is improved.

IPC: H01L29/73
Filed: 1985-02-12
Abstract: PURPOSE:To prevent scattering of impuriteis without loosing saturation characteristics, by preventing the reaching of a depletion layer to a drain by an operating voltage even if the carrier concentration of a channel part is decreased. CONSTITUTION:An insulating layer 7 comprising SiO2 is provided. A window 8 is provided at a channel part corresponding to a part, where carriers flow, in the insulating layer 7. The window 8, which is provided in the insulating layer 7, is not made larger than at least a window between gate electrodes 4. In consideration of the fact that a depletion layer, which is actually formed, is slightly larger than the gate electrode, it is desirable that the insulating film 7 is slightly protruded from each gate electrode 4 and that the window 8 is smaller than the window between the gate electrodes 4. Even if the carrier concentration of a semiconductor layer 1 contacting layer 7 is low, the depletion layer is not extended to the side of a drain. Even if the carrier concentration is decreased, the saturation characteristics are obtained.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a traction cable by surrounding the traction cable by a hold member between a terminal member and a belt buckle and holding the traction cable at a direction change attitude by this hold member. SOLUTION: A traction cable 3 is attached to a vehicle through a mounting member 7. A hold member 9 is arranged close to a belt buckle 1 between the belt buckle 1 and a terminal member 5 so that two traction cable portions 11, 13 are pressed and matched mutually. To provide the belt buckle 1 with a target position which is inclined upward, the belt buckle 1 is brought to the target position first. Next, the hold member 9 is pressed against two traction cable portions 11, 13 to determine the mutual positions of the traction cable portions 11, 13 so that the traction cable 3 cannot return to the start position shown by a broken line. The traction cable 3 is not damaged owing to this work.
