Patent JP-H03104378-A (JP)
Title: Scanning circuit device
Inventor: HIROOKA KAZUYUKI
IPC: H04N5/369
Filed: 1989-09-18
Abstract: PURPOSE:To obtain an output corresponding accurately to the scanning by extracting an output of plural scanned circuit components connected in common in a form of one signal string and applying signal processing control to it with a signal decided based on the detection of a timing when a diode starts its conduction. CONSTITUTION:An integration capacitor 10 is connected between an anode and ground of photoelectric conversion elements S0-S3 and charged by a current flowing to the photoelectric conversion elements S0-S3. A control signal Vr of a discharge switch 11 of the integration capacitor 10 and a control signal Vs of a sample-and-hold circuit 3 are not generated at an interval of a prescribed time but generated at the detection of a change in a current 11 based on the transit of 2nd diodes Db0-Db3 to the on-state. Thus, the read point of time is changed in response to a change in the mutual time width of the on-point of time of the 2nd diodes Db0-Db3. Thus, the read of the output of the photoelectric conversion elements S0-S3 is implemented accurately.

Title: Semiconductor device
Inventor: KURODA SHIGERU
IPC: H01L29/778
Filed: 1983-12-23
Abstract: PURPOSE:To inhibit and prevent the rise and the disconnection of the resistance value of a gate electrode by a method wherein the stepwise difference of the surface for forming a gate electrode metal layer is extremely reduced in a compound semiconductor FET. CONSTITUTION:The thickness of an I-type GaAs layer 14 is set at 50(nm), that of an I-type AlGaAs layer 13 at 250(nm), and that of an I-type GaAs layer 12 at approx. 300(nm). Therefore, the depth from the top of an N type GaAs layer 16 to the top of the layer 13 is approx. 130(nm), and the depth from the top of an N type AlGaAs layer 15 is approx. 80(nm). Even when recess formation is executed after the mesa etching for element isolation by selective dry etching using the layer 15 as a stopping layer, the layer 13 is not actually etched. As a result, the stepwise difference between the electrode part of the gate electrode 17 and a wiring connection region is approx. 80(nm). Also in case the thickness of the gate electrode metal layer is set at approx. 300(nm) the same as conventional, the possibility of its disconnection is eliminated, and the resistance value is kept low.

Title: Method for driving liquid crystal display device
Inventor: SHIMIZU KAN
IPC: G09G3/36
Filed: 1987-09-30
Abstract: PURPOSE:To rewrite a picture in a time less than that when a scan electrode is selected one by one by overlapping the time to select each of the scan electrodes with each other. CONSTITUTION:The rewrite time of the picture is shortened by constituting a signal to select the scan electrode of first-sixth pulses, and generating the fourth-sixth pulses of the signal to select a J-th scan electrode and the first-third pulses of the signal to select a K-th scan electrode at the same time nominally. Also, to suppress a noise generated on the picture at the time of performing the rewrite of the picture at minimum, the signal to be impressed on a control electrode to control the bright/dark state of an image element on the K-th scan electrode is generated at the same time as that of the fourth-sixth pulses nominally. By setting the potential of a seventh or a ninth pulse to be impressed on the control electrode at zero potential selectively, the bright/dark state of the image element can be controlled. In such a way, it is possible to obtain a driving method with a few of noise, without generating nonuniformity in brightness, and operated at high speed.

Title: Optical deflecting mechanism
Inventor: TASHIRO KATSU
IPC: G02B26/12
Filed: 1988-09-30
Abstract: PURPOSE:To correct the inclination of the entirety and the influence of the inclination of reflecting surface by providing a reflection optical system which projects reflected light in the same direction with incident light as the regular projection component of a light beam to a certain surface of a rotary polygon mirror and reflects regularly the regular projection component of a light beam to a surface perpendicular to said surface. CONSTITUTION:The incident laser beam L is reflected (laser beam L1) by one surface of the rotary polygon mirror 1 to travel upward, and the laser beam is made incident on a right-angled bihedral mirror 2 (laser beam L2) and reflected downward by the mirror 2 and reflected by the same reflecting surface of the rotary polygon mirror 1 with the 1st reflection to travel in an image plane direction (laser beam La). The right-angled bihedral mirror 2 reflects regularly the irregular projection component to the surface containing the intersection line of two mirrors constituting the mirror 2, but reflects the projection component to the surface perpendicular to the intersection line of the mirror in the same direction as the direction of the incidence. Consequently, even if the rotary polygon mirror slants during rotation and varies in angle like a rotary polygon mirror 1b and the incidence beam Land projection beam Lb become equal in angle like an incident beam L and a projection beam Lb in a figure.

Title: Control device for motor
Inventor: KATSUMURA HIDETAKA
IPC: H02P5/46
Filed: 1985-10-31
Abstract: PURPOSE:To perform a stable control over all the ranges of operating condition by setting out a transient response characteristic of each speed control system of electric motors group at the shortest response time when the line speed is constant and by changing it to the mutually equal response time when the line speed is increased or decreased. CONSTITUTION:A signal detector 12 detects the change of line speed preset by the line speed reference generating circuit 11 and actuates a relay 13 on its output signal. The gain of R3/R1 of an operational amplifier 5 is set out so as to set the transient response time as fast as possible and the gain of R2/R1 is set at the value necessary for adjusting the transient response time to the other motor 2. The gain of R2/R1 is selected when the relay 13 is actuated, but the gain of R3/R1 is selected while the relay 13 is not actuated. Thus the transient response time becomes mutually equal when the line speed reference changes, and when the line speed reference signal is constant, it can be set to the shortest time.
