Title: Formation of optical waveguide
Inventor: SAWAKI ITSUPEI
IPC: G02B6/122
Filed: 1982-04-14
Abstract: PURPOSE:To eliminate the need for a stage for changing the thickness of metallic layers and depositing the same and to make the change in refractive index continuous by decreasing the width of an optical waveguide gradually in the part where two kinds of the metallic layers to be deposited are connected. CONSTITUTION:Ti layers 6 are deposited on the surface of, for example, a substrate 5. The Ti layer having a larger thickness d2 has the constant thickness up to the terminal end part where the width is decreased gradually and the Ti layer having a smaller thickness d1 maintains the width corresponding to the width of the optical waveguide. The metallic layers which differ in thickness as mentioned above are easily formed if the respective thicknesses are uniform and both layers are segmented simply by the plane shape. The optical waveguide is formed to have a relatively low refractive index in the part of the Ti layer where the thickness is dl and to have a relatively high refractive index in the part of the Ti layer where the thickness is d2. The need for the stage for changing the thickness of the metallic layers continuously is eliminated by the above-mentioned method and the change in the refractive index is made continuous.

Title: Fuel injection device of engine
Inventor: ASAMI YOSHIHIRO
IPC: F02D41/04
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device with which an improved starting characteristic is obtained by transferring the pressure control mode of a working fluid at the engine starting time from the open loop control to feedback control on the basis of the pressure of the working fluid or the elapsed time from the starting. SOLUTION: At the engine starting time, a condition judging means 44 changes over the connection of a switching circuit 43 from a rail pressure correction amount setting means 42 in which the correction amount is set to zero to a rail pressure correction amount calculating means 41 which determines the correction amount through PID control based on the pressure deviation ΔPr when the pressure of the working fluid reaches the set pressure or when the elapsed time from the starting reaches the set time.  The pressure control of the working fluid transfers from the open loop control in which the fundamental rail pressure Prb remains out of correction to the feedback control in which addition of the correction amount is conducted, which leads to suppression of the pressure deviation at transfer and improvement of the starting characteristics including shortening of the time for starting, etc.

Title: Vehicle-mounted phase difference distance meter
Inventor: KAWAMURA KATSUO
IPC: G01C3/06
Filed: 1993-03-22
Abstract: PURPOSE:To achieve and accurate measurement by disposing number of detection elements in vertical direction and then setting the product of base line length and distance between a lens and a sensor to a specific value or larger. CONSTITUTION:A light image of an object to be measured is input through two lenses 3 in a semiconductor chip 1. One line consists of two zones and is constituted of line sensors 11a, 11b, 12a, 12b, 13a, and 13b. Correlation operation is performed between the sensors 11a and 11b, between 12a and 12b, and between 13a and 13b, the phase difference of these formed images until the degree of correlation is minimized is obtained for identifying focusing state, and then distance value is calculated from the phase difference. This kind of vertical installation sensor may be used to measure the distance with a preceding vehicle with a number of side lines for mounting in a vehicle for achieving a high accuracy and is also strong against up/down vibration. When the base line length s set to Bmm and the distance between the lens and the sensor is set to fmm, the resolution increases more as the value of Bf is larger. The Bf should be larger than approximately 200 to measure the distance to a relatively remote object with a high accuracy in the vehicle-mounted phase difference distance meter.

Title: Cmos driver circuit
Inventor: ONO YUKICHI
IPC: H03K19/0175
Filed: 1994-03-31
Abstract: PURPOSE:To reduce the power consumption due to the change in an output voltage by connecting a P-channel FET terminal of a series circuit comprising N and P-channel FETs each having a prescribed threshold voltage to a point of a reference voltage and connecting the N FET terminal to a point of a power supply voltage positive with respect to the reference voltage. CONSTITUTION:The driver circuit is made up of the series connection between an N-channel MOB 1 having a prescrrbed threshold voltage and a P-channel MOS 2 having other prescribed threshold voltage, a drain terminal of the N-channel MOS 1 connects to a point of a power supply voltage VDD and a source terminal of the MOS 1 connects to a source terminal of the MOS 2, and a drain terminal of the P MOS 2 is connected to a point of a ground potential VSS. In this case, the output voltage changes between a voltage higher than the ground potential VSS by a threshold voltage of the PMOS 2 and a voltage lower than the power supply voltage VDD by a threshold voltage of the N MOS 1. That is, the amplitude of the output voltage is reduced, and a charge charged/discharged in/from a load capacitor is limited. Furthermore, even when the amplitude of the output voltage is small, the driver circuit is properly driven by properly setting a threshold voltage for the P-channel MOS 4 and the N-channel MOS 5 of a receiver circuit.

Abstract: PURPOSE:To give much play of a pinch roller at the APS state by adopting the constitution that the pinch roller is spaced away from a capstan shaft when a head base is in the approaching position and a magnetic head is held close to a tape. CONSTITUTION:When a solenoid 3 is energized, a link 4 is turned clockwise, the head base 1 is progressed in the forward position in the direction B, a head 2 is brought into close contact with a tape and the playing is attained. When the solenoid is deenergized and the head base is in the near forward position retrogressed a little, a pin 26 is engaged with a step 28 of a cam hole 27, the turning of a lever 24 is blocked, the base 1 is locked to form the APS state. On the other hand, a moving plate 20 is forward similarly when the solenoid is energized and restores the backward position even at the APS when the solenoid is deenergized. Thus, in using the moving plate 20 provided separately with the head base to control pinch rollers 9, 10 to the capstan shafts 7, 8 the play of the pinch roller at the APS is taken large independently of the retrogressing amoung of the head base 1.
