Title: Light-receiving/emitting apparatus
Inventor: OIMURA KATSUHIKO
IPC: H01L31/10
Filed: 1984-05-28
Abstract: PURPOSE:To increase the speed of response by arranging a light-emitting element in front of a light-receiving element, disposing an electrode plate in a base for the light- emitting element in front of the light-receiving element, partitioning the light-receiving element into a projection section and a shadow section for beams and forming the projection section in a photoelectric conversion section. CONSTITUTION:A PD3 is partitioned into projection sections 31 and shadow sections 32 for beams and constituted, and the shadow sections 32 are positioned at the lower sections of both lead frames 5, 7 for a LED2, and take shapes corresponding to a plate section 5a, one part of a lead section 5b and one part of the lead frame 7 for an anode. On the other hand, circular P-layers 3p are laminated and shaped to rectangular N-layers 3n in the PD3, and the P-layers 3p are formed only to the projection sections 31, thus constituting P-N junctions, then functioning as photoelectric conversion sections. The shadow sections 32 are formed only by the N-layers 3n, have no photoelectric conversion function, and do not contribute to junction capacitance. Accordingly, since the areas of the shadow sections 32 are reduced to approximately 17% as compared with the case when the P-layers 3p are also shaped to the shadow sections 32 and the P-N junctions are constituted, the speed of response on light-reception is increased to 1/(1-0.17)=1.2 times, and augmented by 20%.

Title: Variable valve timing control device
Inventor: KASASHIMA KENJI
IPC: F02D41/04
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a variable valve timing control device capable of suppressing a vehicle slip and ensuring running performance, too. SOLUTION: A variable valve timing control device comprises a variable valve timing mechanism (VVT) adjusting open/close timing of an intake valve 9, various sensors 30A, 30B, 40A, etc., and an electronic control device (ECU) 48 or the like. In the ECU 48, in the case of detecting a slip condition, in the case of a shift position in a low gear position of the first speed, second speed, etc., the VVT is controlled to a retard timing side, a valve overlap amount is decreased. Consequently, torque is decreased, a slip is difficult to occur. In the case of the gear position in a high gear position of the fourth speed, fifth speed, etc., the VVT is controlled to an advance timing side, in this way, the valve overlap amount is increased. Thus in the case of the high gear position, from the first in a condition difficult to slip, running is placed in priority.

Title: Fuel injector for diesel engine
Inventor: UEHARA TETSUYA
IPC: F02M51/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To realize characteristic of the best initial injection rate according to operating conditions by freely controlling characteristic of an injection rate. SOLUTION: In this fuel injector 1 for ejecting high pressure fuel by lifting a needle valve 9 when pressure in a pressure chamber 25 is released, two opening/closing valves (solenoid valves) 22, 23 opened/closed according to operating conditions are equipped in the fuel pressure releasing passage 26 of the pressure chamber 25. These two solenoid valves 22, 23 are changed over according to the operating conditions, thereby the pressure lowering characteristic of the pressure chamber 25 is controlled, and accordingly a fuel injection rate can be changed to different characteristics. For example, by opening only one of solenoid valves 22, 23 in a low/middle rotational range, lowering of pressure is loosened, and low characteristic of an initial injection rate is provided.  In a high rotational range and a high load range, both the solenoid valves 22, 23 are opened, thereby pressure is suddenly steeply lowered, the initial injection rate is enhanced, and reduction of smoke and improvement of output can be achieved.

Title: Rolling method for reducing thickness deviation of sheet
Inventor: NAOI TAKAYUKI
IPC: B21B1/22
Filed: 1979-08-31
Abstract: PURPOSE: To prevent the fluctuation of the rolling load due to the keyway, and to improve the thickness accuracy of the sheet, by providing the finishing mill with the oil film bearing to be set by the key at a specified distance from the end of the fitting zone between the sleeve and the rolling roll.  
     CONSTITUTION: The sleeve is set to the taper neck of the rolling roll with the key at a position 0.2 or more times of length of the pressure receiving zone of the oil film bearing distant from the end of the fitting zone between the sleeve and the taper neck of the rolling roll, that is the position excluded from the fitting zone. Next, this bearing is employed in at least the final stand of the finishing mill or the finishing mill group of the thick plate hot rolling plant. The reason of this employment of said oil film bearing is explained as follows; even if the finishing mill attains a high thickness accuracty, if the bearing of the final stand is one of the conventional style, the run-out side thickness accuracy is degraded as a result of being affected by the fluctuation of the roll gap because of the deformation of the keyway.

IPC: H03K3/57
Filed: 1989-04-28
Abstract: PURPOSE:To increase the fluctuation permissible range of an AC power voltage by connecting a series circuit comprising a rectifier diode and a resistor in parallel with a capacitor. CONSTITUTION:A series circuit comprising a rectifier diode D2 and a resistor R2 is connected in parallel with a capacitor C. With the application of a voltage VAC of an AC power supply, the capacitor C is charged, a voltage VC reaches a break-over voltage of a two-terminal thyristor THY, which is turned on. When charging is stopped, the capacitor voltage VC changes from discharge into charging according to the polarity of a negative half cycle of the voltage VAC and the voltage VC reaches the negative state at the zero point of the voltage VAC. Thus, the charging quantity till the voltage VC reaches the voltage VBO is sufficiently increased. The increase in the charge quantity expands the fluctuation permissible range of an AC power supply voltage for generation of one cycle one pulse.
