Title: Image forming device
Inventor: SHIMAZAKI TAKASHI
IPC: G03G15/08
Filed: 1986-11-12
Abstract: PURPOSE:To prevent a device from increasing in size and to reduce the cost of the device by using the same developing device and developer for both normal development for obtaining a positive-positive image only by processing elements required for reversal development and the reversal development for obtaining a negative-positive image. CONSTITUTION:When a positive (P) is developed from a negative (N), the development is performed similarly to a general method. Then when a P-P development selection key is depressed for P-P development, an electrostatic charger 304 charges a photosensitive body 301 negatively at -600V. Then, a photosensitive body 301 is irradiated with scanning light from a microfilm by the scanning of a rotary mirror to attenuate the surface potential of the photosensitive body 301, so a potential remain only at character parts to form electrostatic latent images corresponding to the characters, and a magnetic roll 333 is applied with a bias voltage Vb=-300 to develop negative images corresponding to the characters on the photosensitive body 301: when the photosensitive body is charged electrostatically at -600V by the electrostatic charger 304 and the entire surface is irradiated with light, the surface potential is attenuated and inverted by a magnetic roll 333 to attract toner to the character parts, and the toner is fixed by an electrostatic charger 307.

Title: Method of driving optical pickup
Inventor: KOIDE HIROSHI
IPC: G11B7/085
Filed: 1984-12-21
Abstract: PURPOSE:To reduce gain of a controlling loop by feeding forward output of a position detecting device to the first control loop or feeding forward a signal corresponding to driving current of a motor for tracking or making both of these feeding forward together. CONSTITUTION:As it becomes XP-XC at a summing point 206, delta is outputted to the right of the summing point 206.

On the other hand, as it is a signal (i) corresponding to driving current to a motor for tracking which is transmitted to the right of a summing point 104, this is multiplied by a transmission function (KT/KS) (MC/MP+1) and fed forward to a summing point 204 of the second controlling loop 204, and driving of a light pickup 10 allowing for elastic reaction of a leaf spring is made. Thus, decrease of gain due to elastic reaction can be made small.

Filed: 1988-10-25
Abstract: PURPOSE:To eliminate luminance dispersion due to the dispersion of responsibility between the ICs and to improve a picture quality by imposing a variable resistance between the Vcc terminal of a beam stream control electrode driving IC and a power source. CONSTITUTION:Beam stream control signals from a beam stream control signal generating circuit are inputted to ICs 61a to 61b, and impressed to respective conductive plates 15-1 to 15-n of a beam stream control electrode 5 after amplification. The ICs 61a to 61b consist of pulse amplifiers 62a to 62c, and by serially inserting semi-fixed resistances 63a to 63b between the Vcc terminals of the ICs 61a to 61b and the power source VB, since the potentials of the Vcc terminals of the ICs 61a to 61b fall by a sharp current increase at the time of the leading edge of the signal, a rise time becomes slower than that without the semi-fixed resistances 63a to 63b. Therefore, by changing the resistance values of the semi-fixed resistances 63a to 63b, responsibility can be regulated, and the dispersion of the responsibility between the ICs can be eliminated.

Title: Semiconductor switch
Inventor: TAKEDA MASATOSHI
IPC: H03K17/725
Filed: 1986-11-13
Abstract: PURPOSE:To reduce the power consumption and to simplify the circuit by giving a gate current for triggering itself from a voltage between input and output electrodes of a main semiconductor element during the ON period and stopping the flowing of the gate current in receiving an OFF signal so as to turn off a semiconductor switch and self-holding the operation. CONSTITUTION:In turning off main thyristors 6a, 6b, when either an auxiliary thyristor 15a or 15b is once turned on, the thyristors 15a, 15b hold the on-state. As a result, resistors 9, 11 are short-circuited respectively by the auxiliary thyristors 15a, 15b and no gate current flows to the main thyristors 6a, 6b through diodes 13a, 13b, then the main thyristors 6a, 6b keep the OFF state. In turning on the thyristor switch, when the main thyristors 6a, 6b are turned on once, the thyristor switch can keep the ON state without an ON command. Thus, even when the ON period of the semiconductor switch durates long, the titled switch can be constituted by a gate signal generator with a small power.
