Title: Photoelectric converter
Inventor: HASHIMOTO SEIJI
IPC: H04N5/374
Filed: 1988-03-28
Abstract: PURPOSE:To eliminate an undesired component such as noise from a photoelectric conversion output by storing the 1st and 2nd signals from the photoelectric conversion element to the 1st and 2nd storage means and reading the 1st and 2nd signals superimposingly. CONSTITUTION:While pulses phihr, phih1-phihn are kept as they are, a capacitor c1 is connected to ground through transistors(TRs) Qh, Qhr to bring the pulse phivc into a low level thereby floating the level of the emitter of a sensor S. Thus, the noise component of the optical sensor S after refresh is transferred and stored into capacitors cv, c1. When the storage period (c) is finished, the pulse phir rises, and a sensor signal corresponding to the incident luminous quantity is read out and transferred to the capacitor cv and stored therein. Then horizontal scanning pulses phih1-phihn are sequentially brought into a high level succeedingly and the signal sout being the result of eliminating noise component from the sensor signal is outputted externally sequentially from a horizontal output line HL.

Title: Inhaled air quantity detector
Inventor: MATSUBARA MAMORU
IPC: G01F1/692
Filed: 1989-03-24
Abstract: PURPOSE:To secure the stable detection accuracy by fixing a base end part of a beam material of a detecting element, and inserting and holding the tip part by an elastic member. CONSTITUTION:As for a detecting element 10, its base end part is fixed to a holder 1, and its tip part is inserted and held between elastic members 4a, 4b. Accordingly, even if vibration of an internal combustion engine is transferred to the holder 1 through an inhaling cylinder, there is no possibility that the element 10 is resonated. Also, even if a relative movement is generated between the holder 1 and the element 10 due to a difference of thermal expansion coefficients between both of them, since the tip part of the element 10 is supported by the holder 1 with a prescribed gap, it is absorbed by this part, and no detection error is caused by a thermal expansion.

Filed: 1985-04-05
Abstract: PURPOSE:To make possible the application of a ceramic mold to a large-sized casting by embedding reinforcing materials consisting of high-strength ceramics into a part corresponding to a core and projecting part which receives buoyancy and impact from a molten metal in the stage of casting. CONSTITUTION:The reinforcing materials 4 consisting of the high-strength ceramics formed by press sintering, etc. are embedded into the part 2 corresponding to the core and the projecting part 3, etc. which receive the buoyancy and impact from the molten metal during casting and these materials and parts are integrally molded and calcined in the stage of producing a ceramic shell1.

Title: Optical wave distance meter having optical delay means
Inventor: OISHI MASAHIRO
IPC: G01S17/10
Filed: 1992-02-21
Abstract: PURPOSE:To avoid induction noise and to reduce a linear error by forming an optical delay means making the emission pulse width of a light source part smaller than the passing time of an emission pulse through an internal reference passage. CONSTITUTION:The light pulse emitted from a photodiode 1 passes through an optical system to be converted to an electric signal of a current pulse train by an APD 71 and the output signal of an amplifier 160 is converted to binarized digital data by a waveform shaping circuit 170. An operation circuit 3000 operates the distance up to a corner cube 11 from the time measured by an interpolation circuit 2000. A delaying optical fiber 8 makes the emission pulse width T1 of the laser diode 1 smaller than the passing time of an emission pulse through the internal reference light path from the laser diode 1 to the APD 71. By this constitution, the received pulse in the internal reference light path and the received pulse in an external distance measuring light path receive is not subjected to induction noise. Therefore, the distance up to the corner cube 11 can be measured without being subjected to the induction noise accompanied by the emission of the laser diode 1.

Abstract: PURPOSE:To enable the slanted angle from a specified lattice face of a single crystal plane to be measured with a high precision of about 1/1,000 deg., by measuring the distance between two peaks in a locking curve. CONSTITUTION:An X-ray beam 2 irradiated from a ray source 1 passes slits 3 and 4, is applied on a monochrometer 5, and becomes approximately parallel X-ray beams. Said X-ray beams are irradiated on a specimen 7, and rotated around the axis O of the specimen 7. The intensity of a reflected X-rays 8 are measured by a counter 9, and the X-ray locking curve is obtained. In the case incident X-ray OR (and OT) are inputted to the surface of a specimen 30 at a shallow angel, a large peak appears at a position thetaR which is separated by a normal black angle thetaB-DELTAH by a reflected X-ray HR. In the case part of OT is irradiated to the side of the specimen, it is diffracted in the specimen 30 and outptted as an X-ray HT, and the small peak is obtained at position thetaT. The value of the distance DELTAH can be directly measured approximately by a formula DELTAH=thetaR-thetaBapprox.=thetaR-thetaT.

Title: Motor rotating speed control system
Inventor: SUZUKI KEIICHI
IPC: H02P29/00
Filed: 1983-04-25
Abstract: PURPOSE:To eliminate the need for an adjusting circuit and to quicken the response of ontrol by always supervising the maximum pulse width of a data signal detected from a disc, and applying to a driving motor of the disc with an auxiliary control voltage returning a pulse width to a reference value when the maximum pulse width goes outside of the operating range of a PLL. CONSTITUTION:A binary counter 21 of an auxiliary control voltage generating circuit 20 counts a reference clock signal by a period of H level of a data signal S. X is its counted value and it is increased as the pluse width is longer. Magnitude comparators 22, 23 compare the X and its upper and lower limit values Y1, Y2. X>Y1 means that the rotating speed of the disc 1 is lower than the reference value and the comparator 22 brings an output Z1 to H level and increases a control voltage Vc'. That is, an output of a charge pump circuit 28 goes to an up-signal. Conversely, X<Y2 indicates that the rotating speed of the disc 1 is higher than the reference, the comparator 23 brings an output Z2 to L level and an output of the charge pump circuit 28 becomes a down-signal.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of providing a different member coming into contact with a roller and to prevent staining on a paper sheet caused by the wearing of the roller and the soiling of a cleaning member by adopting such a constitution that retained toner is recovered into a paper peeling pawl. SOLUTION: The paper peeling pawl 4 is provided in a contact state with the surface of a heating/fixing roller. The paper peeling pawl 4 is provided with a space part for recovering the retained toner inside. During standing by after consecutive operations, toner is heaped on the top end of the peeling pawl 4, but the toner is housed in the space part in a toner recovering part 7 through an opening part, 8. Then, the toner in the toner recovering part 7 is carried to a toner recovering container through an air duct, to be retained in the container, in such a manner that an air sucking device is operated at a fixed period or all times. Therefore, the toner is prevented from remaining retained at the top end of the peeling pawl 4 and the staining of the paper with the retrained toner is prevented as well. Thus, the inside of a machine is never soiled with the scattered toner.
