Title: Optical tachometer
Inventor: NAGAI TAKASHI
IPC: H02P29/00
Filed: 1979-06-11
Abstract: PURPOSE: To prevent the influence of temperature change, by using a prescribed circuit to detect the rotation speed and the rotation direction with one element in the optical tachometer which is provided with a light emitting element and a photodetector and has a rotary slit and a fixed slit.  
     CONSTITUTION: In respect to rotary slit 2 fixed to shaft 1, plural light transmission parts and black light shielding parts are provided alternately on a glass disc radially. In respect to fixed slit 6, plural slender right-angled triangular light transmission holes 11 are provided on a metallic plate. The light from light emitting element 5 is received by photodetector 7, and the rotation speed of the shaft is detected through waveform shaping circuit 8 from the period of the square wave. Meanwhile, when the output of photodetector 7 is input to one shot multivibrator 16 through differentiating circuit 12, slicer 13, differentiating circuit 14 and slicer 15, the rotation direction can be detected because the output becomes a high level and a low level for clockwise rotation and counterclockwise rotation respectively. Since only one-group slits are used as the fixed slit, the influence of temperature can be prevented.

Title: Paste type negative electrode for alkaline storage battery
Inventor: KAWANO HIROSHI
IPC: H01M4/02
Filed: 1987-03-26
Abstract: PURPOSE:To secure the electron conductivity and prevent the corrosion of copper in an alkaline electrolyte by filling a paste-shaped negative electrode active material partially containing the charged negative electrode active material into a sintered porous body made by sintering copper fibers. CONSTITUTION:A paste-shaped negative electrode active material partially containing the charged negative electrode active material is filled into a sintered porous body made by sintering copper fibers. According to this constitution, even directly after the electrolyte filling process which is one of processes to constitute a battery is completed, a negative electrode indicates the normal potential. Such a potential that copper is dissolved in an alkaline electrolyte is not therefore attained. Owing to this action, the dissolution of copper into the electrolyte can be prevented, and the deterioration of the battery characteristic can be prevented.

Title: Printing method for crt image containing character
Inventor: YAMAGUCHI KIYOSHI
IPC: G03B27/32
Filed: 1986-04-01
Abstract: PURPOSE:To improve character quality and to easily enter characters by erasing CRT image data which is superposed upon a character plate among CRT image data recorded in a memory and writing light emission data for lighting the character plate instead. CONSTITUTION:When there is a CRT image in a character recording area where the character plate 26 is superposed, data on this CRT image is deleted from the frame memory, and the light emission data corresponding to the color of characters to be recorded is written instead to allow a CRT11 to emit light based upon the light emission data. This light emission data is written by specifying the position and color of the character recording area on a keyboard 57; when the light emission data no only one color is written, monochromatic characters are displayed and when the light emission data on colors are written, a composite color display is obtained. Actually, the light emission data is written by software. Consequently, the characters neither blurs at their contour nor become fogged owing to a defect in contacting and even small characters can be sharply printed.

Abstract: PURPOSE:To increase the working speed of a photodetector, and to improve the high-frequency characteristics of the photodetector by setting the impurity concentration of the emitter of a reverse transistor in an IIL(Integrated Injection Logic) region independent of the concentration of an epitaxial layer. CONSTITUTION:An N well formed by an impurity region 15 is shaped so as to cover an internal base region 16, thus setting the impurity concentration of the emitter of a reverse transistor in an IIL region regardless of the impurity concentration of an epitaxial layer 13. Consequently, the impurity concentration of the impurity region 15 is set at a high value and the impurity concentration of the emitter can be increased, and the epitaxial layer 13 can be shaped at high resistivity as 40OMEGA.cm. As a result, the impurity concentration of the epitaxial layer 13 interposed between the impurity region 21 of a photodiode formed in a light-receiving circuit region and an impurity region 25 is lowered, and junction capacitance generated between the anode 21 and the cathode 13 is reduced. Accordingly, the photodiode is operated at high speed, and the high- frequency characteristics of the photodiode are improved.

Abstract: PURPOSE:To permit to apply electric brake without imposing a burden on a generator within an allowable limit of an increase in temperature for a winding by reducing the field current of the generator in directly proportional to the rotational frequency of the generator at the time of generating brake for the generator. CONSTITUTION:With a braker 5 and a field braker 14 opened by a stop command, the field current will quickly attenuated by a field discharge resistor 15 and a disconnector 2 for generating brake is turned on when the voltage of a generator 1 decreases up to residual voltage to transfer a change-over circuit 12 to a firing angle control circuit 16 from an AVR10. When the rotational frequency decreases by mechanical loss or the like during the above period and the rotational frequency decreases enough to apply generating brake, the breaker 14 is again turned on. Cooling effect is still high even for a self-ventilating generator at the initial stage of generating brake application. Therefore, braking effect is increased by flowing a braking current up to some extent of the rated current of the generator 1 and speed is detected by a speed generator 7 as the rotational frequency decreases and the field current is decreased in directly proportional to speed.
