Title: Low-alloy steel
Inventor: ISHIBASHI YASUHIRO
IPC: C22C38/00
Filed: 1980-10-07
Abstract: PURPOSE: To obtain a low-alloy steel with improved temper brittleness by adding La to a conventional low-alloy steel.  
     CONSTITUTION: This low-alloy steel consists of ≤0.15% C, ≤0.5 Si, 0.3W0.6% Mn, ≤0.035% P, ≤0.035% S, 2.0W2.5% Cr, 0.9W1.1% Mo, ≤0.2% La and the balance Fe with inevitable impurities. Temper brittleness is caused because impurities such as P, S and Sn are diffused and thickened by long-time use at high temp. Accordingly, by adding La having a great affinity for said impurities and forming stable deposits in grains and on grain boundaries at about 200W600°C, the diffusion and thickening of the impurities on the grain boundaries are reduced or prevented, and deterioration impact value by long-time use at high temp. is prevented. >0.2% La lowers the impact value.

Title: Trap system
Inventor: TAKI YOSHIHARU
IPC: G06F11/28
Filed: 1981-09-09
Abstract: PURPOSE:To eliminate an ineffective interruption of trap, by applying an interruption only in case the contents of a storage device or a register are changed due to a defect of a program. CONSTITUTION:When a memory changing trap is carried out, the address of a storage device MEM with which a program defect is expected is previously set to a trap address register 11. At the same time, the normal data corresponding to the address shown by the register 11 is set to a trap data register 12. The bit position 2 of a trap control register 10 is set at 1. Then the address in a memory address register 13 which is replaced by a coincidence circuit 20 with each writing to the MEM is collated with the address in the register 11. In case the coincidence is detected between both addresses and at the same time the discordance is detected between the writing data in a memory data register 14 corresponding to the relevant address and the normal data in the register 12, a defect of the program is decided. Thus an interruption is applied to an interrupting circuit via an AND circuit 40 and an OR circuit 50.

Title: Laser diode driver circuit
Inventor: ENDO TAKEMI
IPC: H03K17/78
Filed: 1985-06-27
Abstract: PURPOSE:To improve productivity by connecting a clamping circuit to the FET which drives a laser diode, thereby enabling the gate voltage to be set to the pinch-off voltage by changing the clamp voltage even if the characteristics of the FET fluctuate. CONSTITUTION:When a DC current exceeding a certain current is made to flow through a clamping diode D, its voltage drop is a constant value VD. Therefore, if a clamp voltage VB is applied to the clamping diode D, the gate voltage of a FET 2 is the clamp voltage VB minus the voltage drop VD in the clamping diode D. Since the clamp voltage can be appropriately applied by voltage varying means, it can easily be adjusted even if the pinch-off voltage varies. Thus, when an input voltage Vin is applied, the source-drain current flows through the FET 2, and a laser diode 1 emits light.

Abstract: PURPOSE:To obtain an excellent image where carrier is not attached even when a developer resistance value is varied by detecting a current flowing between a developing device and an image carrier and controlling a developing bias voltage outputted from a developing bias voltage impressing means according to the current value. CONSTITUTION:By a bias power source 41 being as the developing bias voltage impressing means, the developing bias voltage VB is impressed between a photosensitive drum 13 and a developing roller 18. The current flowing between the roller 18 and the drum 13 is inputted to an A/D converter 51 after it is changed to a developing detection voltage VD by an amplifier circuit 53. In a control means 43, an arithmetic processor 47 compares data XD inputted from the converter 51 with data stored in a memory part 49 and adjusts the developing bias voltage VB outputted from the power source 41 according to the compared result. Thus, the carrier is prevented from being attached and the excellent image is always obtained.
