Title: Detachable light transmission-detection part of light transmission system
Inventor: OKADA SHIGEO
IPC: H01L31/0232
Filed: 1980-02-16
Abstract: PURPOSE:To obtain a detachable light transmission-detection part of a light transmission efficiency and stability, by forming a sleeve so that only both ends of a short-sized optical fiber will be exposed. CONSTITUTION:In cap 5, short-sized optical fiber 4 is buries in sleeve 3 entirely anf fixed in the hole with both its flanks exposed. Then, the top end of optical fiber 4 opposes to the flank of long-sized optical fiber 4, exposed to the tip of the projection part of plug body 8, nearly in contact, and the lower flank is close to light transmitting-detecting element 1. Consequently, the work equipping operation of sleeve 3 is facilitated and optical fiber 4 is never damaged.

Title: Data output circuit of dram
Inventor: PYON HON BOMU
IPC: G11C7/10
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To improve operation rate through transition of a data output control signal only when a column address strobe signal first becomes a low level signal based on the column zero signal, an equalizer start zero signal, data output control OB signal and row address strobe signal. SOLUTION: A first delay means 33 receives an equalizer middle signal and a mode selection signal to generate an output control signal and then it sends the signal to DOE generating means 34 via a switch means 36 to delay the generation of the data output control signal DOE. A control means 35 checks a column address setup time to recognize the first cycle based on the column zero signal, equalizer start zero signal, data output control KOB signal and row address strobe signal. In the first cycle, the switch means 36 is controlled so that the output control signal of the first delay means 33 is caused to pass the DOE generating means 34. Thereby, it is prevented that the invalid data is generated in the first cycle.

Title: Product sum arithmetic unit
Inventor: UEDA KATSUHIKO
IPC: G06F17/10
Filed: 1990-01-29
Abstract: PURPOSE:To perform the cumulative addition of the 16-bit length as well as the multiplication with use of the clocks in number larger than the clocks required for the multiplication by a single clock only by providing a 3rd register which loads the output of an adder means when this adder means performs the addition. CONSTITUTION:The multiplicands produced by a multiplexer 105 are totalized by an adder 111 for execution of the multiplication. In this totalizing process, the outputs of the 1st and 2nd shift registers 113 and 114 (whose contents serve as the lower rank side data on the result of totalization of hitherto multiplication) are also added together. Then the results obtained by adding the lower rank side data on the current multiplication result to the precedent one are held in both registers 113 and 114. Then the higher rank bits of the current multiplication result are added to the output of a 3rd register 115 (whose contents serve as the higher rank side data on the result of totalization of hitherto multiplication) after the end of multiplication. Thus the updated multiplication totalization result is held in the register 115. As a result, the hardware scale is reduced and at the same time the multiplication and the totalization of multiplication results can be carried out at a high speed.

Title: Image forming device
Inventor: SAKAKIBARA HIROYUKI
IPC: G03G15/16
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent defective transfer and transfer omission caused by the change of a resistance value by deciding transfer bias in accordance with the resistance values of a transfer roller and a transfer material. SOLUTION: The transfer bias is applied to the transfer roller by a transfer bias power source while holding and carrying the transfer material by a transfer nip constituted by bringing the transfer roller into contact with the surface of a photoreceptive drum, so that a toner image on the photoreceptive drum is transferred on the surface of the transfer material. Then, the transfer bias applied to the transfer roller is controlled by controlling the transfer bias power source by a controller. The controller executes ATVC(active transfer voltage control) control and detects output voltage Vo to be the constant current control of 2 μmA before the transfer material passes the transfer nip (S3 and S4), and outputs a proper transfer voltage value Vt (S5).  A leaked current leaking to a pre-transfer guide from the transfer roller through the transfer material is detected after the transfer material rushes in the transfer nip (S6 and S7), and it decides whether to be low resistance paper transfer high voltage output (S9) or normal transfer high voltage output (S10) in accordance with a detected result, so that image forming is executed (S11).
