Title: Throttle controller
Inventor: NAKAJIMA HIROSHI
IPC: F02D9/02
Filed: 1989-09-25
Abstract: PURPOSE:To continue an operation even during inoperation of a throttle driving means by directly driving a throttle valve using an accelerator operating mechanism, and warning an operator upon inoperation of the throttle driving means caused by any abnormality. CONSTITUTION:A controller M3 controls a throttle driving means M2 according to the operation of an accelerator operating mechanism M1, the operational condition of an internal combustion engine 9, and the traveling state of a vehi cle, to control the opening of a throttle valve 11. The operational condition of the throttle driving means M2 is monitored. Upon detection of an abnormal ity, the throttle driving means M2 is made inoperative while the throttle valve 11 can be directly driven by the accelerator operating mechanism M1 as well as a warning means M4 gives the notification of the abnormality. Accordingly, in case where the throttle driving means cannot be controlled and operation force and amount differ from those before the abnormality, by certainly inform ing an operator that the throttle valve can be driven by the operation of the accelerator the operation is continued.

Title: Optical pickup device
Inventor: TAKEDA TADASHI
IPC: G11B7/135
Filed: 1995-09-01
Abstract: PURPOSE: To eliminate the effect of a desensitized area of a divided photodetector, to detect a signal highly sensitively and to simplify a device by providing a hologram element provided with a hologram pattern of which diffraction condition is different from each other on an optical path between a light source and a recording medium. CONSTITUTION: A tracking error signal TE and a focusing error signal FE are obtained by luminous fluxes (± first-order light beams) diffracted by the hologram element having a diffraction grating, and on the other hand, a zero- order light component not diffracted is used only for obtaining a high frequency signal RF. Thus, since the necessity using the divided detector is eliminated for detecting the high frequency signal RF, and the effect of the desensitized area of the photodetector is eliminated, the signal with an excellent jitters characteristic is detected without changing the amplitude of the high frequency signal RF even when a spot size is increased/decreased, and a spot position is moved. Further, by integrating the photodetectors, and by using only irreducible minimum photodetectors 21-23, signal processing is simplified.

Title: Starting system for engine
Inventor: IWAKURA YOICHI
IPC: F02D41/06
Filed: 1984-11-26
Abstract: PURPOSE:To eliminate the engine disorder immediately after the complete combustion by gradually reducing the fuel injection amount to the value for the state after perfect combustion after the lapse of a prescribed transient time from the time-point of transfer of the engine from cranking operation to the perfect combustion. CONSTITUTION:When a judging means 7 judges from the engine revolution speed detected by a revolution-speed detecting means 6 that an engine shifts from cranking operation to the complete combustion operation, an opening-degree instruction means 8 outputs the opening and closing instruction for the state after the complete combustion in substitution for the opening and closing instruction for cranking state. Therefor, a valve opening-degree adjusting means 5 for shifting the closing position of a throttle valve 2 is operated by a prescribed amount in the direction of opening. Further, the injection instruction for cranking time outputted from a fuel injection-amount instruction means 9 after the lapse of a prescribed transient time from the above-described judging time-point is shifted to the injection instruction for the state after the complete combustion. Therefore, the fuel injection amount by a fuel injection means 4 is gradually reduced to the value for the state after the complete combustion during the above- described transient time.

Title: Head amplifier
Inventor: SHIMADA KOSHIN
IPC: H03F3/16
Filed: 1984-11-28
Abstract: PURPOSE:To obtain a head amplifier immune to an external noise by using a bootstrap and increasing the power supply impedance so as to increase the DC stability of a gate. CONSTITUTION:A resistor R2 and a gate of an inverted transistor (TR)Q2 are connected to a drain of an FETQ1 and the emitter of the TRQ2 and the resistor R2 are connected to a power supply respectively. Then even when a capacitor C1 is <=10pF and the input impedance Zin is high, since the power impedance of a Crss is high, even if an external disturbance is given from the power supply via the Crss, the change in the gate voltage is small. Further, the source of the FETQ1 is divided resistors R3, R4 and a bias is given to a branch point and the gate through a high resistance. Thus, the Zin is increased by the bootstrap effect and the resistance R1 is set small comparatively in this case. Thus, the stability of the gate voltage against external disturbance is improved.

Title: Sheet conveying device
Inventor: ANDO HIDEKAZU
IPC: B65H1/02
Filed: 1991-09-03
Abstract: PURPOSE:To prevent an oblique movement of a sheet member securely by bending a part of the side end edge of the sheet member so as to increase the resistance to buckling. CONSTITUTION:Between a sheet feeding tray 2 sloped sharply, and a sheet feeding roller 20, a guide member 6 which has a bending 7 is provided. At both the left and the right ends of the bending 7, side regulating plates 10 to guide both the left and the right end edges of sheet members P are provided. When the sheet feeding roller 20 gives an oblique feeding force (a force to move a sheet member obliquely) to the sheet member P to be fed, the side end edge of the sheet member P is squeezed by the side regulating plate 10, but since the part of the sheet member P is bent, the side end edge of the sheet member P generates no buckling even though a large force to correct the oblique movement of the sheet member P is operated from the side regulating plate 10. Consequently, the oblique movement of the sheet member P is prevented effectively.
