Title: Reader for optical recording disk
Inventor: KUWABARA TORU
IPC: G11B7/135
Filed: 1987-08-20
Abstract: PURPOSE:To shorten the access time of an optical pickup, by incorporating two or more optical systems in the optical pickup, and arranging the objective lens of each optical system along the radius direction of an optical disk. CONSTITUTION:The optical disk 1 incorporates two pairs of optical systems A and B, and the optical system A being positioned nearer to the center of the optical disk 1 takes charge of access at an inner peripheral side, and the optical system B separated from the center takes charge of the access at an outer peripheral side. In other words, assuming that the optical system A, when reading track information at the inner periphery of the optical disk 1, receives an instruction to read the track information at the outer periphery next, the optical pickup 10 moves in the radius direction toward the outside. And when another optical system B arrives at a targeted track, the pickup stops, simultaneously, the optical system B reads the track information. In such a way, it is possible to shorten the access time as the optical pickup.

Title: Developer for electrostatic latent image
Inventor: MATSUBARA AKITOSHI
IPC: G03G9/087
Filed: 1987-08-19
Abstract: PURPOSE:To obtain a clear picture image having high resolution and high sharpness and contg. no fog by preventing filming of toner by using silicone resin particles with a toner. CONSTITUTION:The title developer consists of a toner having electrostatically or physically adhered fine silicon resin particles having smaller mean particle size than the mean particle size of the toner on the surface of toner particles by prepg. the toner from a mixture of a toner with said silicon resin. By using such developer, film formation of the toner on the surface of a photosensitive body is inhibited because the toner particles sticking to the surface of the photosensitive body comes into contact with the surface of the photosensitive body interposing fine silicone resin particles having less surface energy and having less adhesivity. Moreover, improved cleaning effect is obtd. in a stage of cleaning residual toner on the surface of the photosensitive body because of less adhesivity of the toner particles to the surface of the photosensitive body. Accordingly, conscientious development of an electrostatic latent image is achieved, and a picture image having high resolution and high sharpness is obtd. without causing sticking of toner to the periphery of the picture image due to insufficiency of electric charge.

Abstract: PROBLEM TO BE SOLVED: To prevent static current from increasing at the time of bias voltage change, to suppress static power consumption and to improve an output signal transition speed by accurately converting a TTL logic signal into a CMOS logic signal and adjusting an output level of a CMOS. SOLUTION: When a TTL input signal Din is high, an output signal Dout of an inverter part 10 becomes low. The level of a 1st node 410 is stabilized to a low state together with an output of a 1st NMOS transistor 401 by making it feedback, a signal from the node 410 makes a 2nd node 411 completely high, and a PMOS transistor 101 for pull-up is turned off to perform current shutdown. Also, since the difference between the input signal Din and internal power supply voltage Vint, i.e., between a gate and a source is smaller than a threshold, a 2nd NMOS transistor 403 is turned off and the transistor 101 is influenced by the output of a PMOS transistor 402 of a PMOS adjusting part 20. Then, an output signal Dout maintains a low state and suppresses static power consumption.

Title: Photochemical reaction device
Inventor: MOCHIZUKI YASUHIRO
IPC: H01L21/263
Filed: 1986-09-05
Abstract: PURPOSE:To prevent the generation of an undesired film deposition and fine grains generated on the inner surface of the light incidence window of a reaction device by a method wherein a substrate is irradiated with excitation light in a highly efficient manner by reflecting it on the side face of the gap of a separator, and the conductance of reaction gas and the gas which does not contribute to the reaction is properly controlled using the gap located between the separators. CONSTITUTION:Excitation light 1 becomes 1a which reaches a substrate directly passing through a gap, or 1b which reaches the substrate after reaction on the sidewall of the gap of a separator. As a result, the excitation light is not shielded by the separator, and it can be made to irradiate on the substrate efficiently. Also, as the conductance of gas based on the gap is determined by the thickness (x) of the separator, the size of the gap (y) and the angle of the gap (theta), the mixture of the reactive gas and the gas which does not reactively controlled can be prevented, and the generation of turbulence of reaciton gas stream can also be prevented. As a result, the illuminance of excitation light on the reaction system, especially on the substrate is not reduced, the turbulence of the reaction gas stream is small, and an optical CVD device, having excellent cloudiness preventing effect of the light incidence window, can be obtained.

Title: Semiconductor memory device
Inventor: OKINA KATSUMI
IPC: G11C7/00
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To provide an FIFO(First-In, First-Out) memory which easily assure desired capacity structure by simplifying and using in common the counter reset circuit. SOLUTION: This memory device comprises a counter reset signal generating circuit which generates a reset signal by a host signal obtained by predecoding the maximum word signal or address. In this case, when a write counter 105 generates a maximum write address, the write address signal is decoded by a write address decoder 104 and as a result the maximum write word signal WW9 rises. In this timing, the write counter reset circuit 107 detects the rising edge of the signal WW9 to raise the write counter reset signal WRST. Therefore, the write counter is reset to generate the minimum write address O. Subsequently, the write counter repeats sequentially the count-up operation until the maximum write address is generated again.
