Title: Production of steel having sulfide corrosion resistance
Inventor: INA KATSUTOSHI
IPC: C21D6/00
Filed: 1980-12-26
Abstract: PURPOSE: To produce steel having superior corrosion resistance and sulfide corrosion cracking resistance by subjecting low alloy steel contg. C, Si, Mn, Co to a high temp. oxidation treatment and forming a Co-enriched layer at the boundary between oxide scale and steel base.  
     CONSTITUTION: The product produced from the molten steel contg. 0.05W0.50% C, 0.05W1.00% Si, 0.10W2.00% Mn, and 0.03W0.55% Co by wt%, and consisting of the balance Fe and unavoidable impurities or the product consisting in applying a heat treatment to this product is subjected to a high temp. oxidation treatment. Then, a layer enriched of the concn. of Co at a number of times the content of Co is formed at the boundary between oxide scale and steel base. The Co-enriched layer acts as a protecting film which prevents the entry of the hydrogen produced by corrosion into the steel in a wet environment contg. H 2 S and prevents the occurrence and propagation of sulfide corrosion cracking.

Title: Image forming device
Inventor: IWASAKI HIROAKI
IPC: G03G21/00
Filed: 1993-07-27
Abstract: PURPOSE:To surely prevent such defect on an image as pin hole from occurring even though an image forming device is used at a higher charging voltage regardless of the constitution of a photoreceptor, and to always form the good image by connecting the conductive base body of the photoreceptor onto a grounding side through an electrolytic capacitor. CONSTITUTION:The photoreceptor D is constituted by forming a photosensitive layer D2 which is constituted of an organic material having photoconductivity and which has single layer structure or multilayer structure of two or more layers on the surface of the cylindrical conductive base body D1 such as an aluminum tube stock. The conductive base body D1 is connected to the grounding side of a power source circuit on the device through the electrolytic capacitor 1. The surface of the photosensitive layer D2 is evenly electrified by corona discharge by means of a charger T1 for electrification. At this time, an excess current generated at a part having the distortion of the photoreceptor D is absorbed by the electrolytic capacitor 1 intervening between the conductive base body D1 of the photoreceptor D and the grounding side of the power source circuit of the device, so that the pin hole is prevented from occurring.

Title: Engine controller
Inventor: SASAKI SHOJI
IPC: F02D41/06
Filed: 1988-07-27
Abstract: PURPOSE:To make it possible to make effective use of learning results by inhibiting an initial setting of data while an engine is being started or operated regardless of lowering of an electric source voltage. CONSTITUTION:In an engine controller 1, in response to generation of a NMI signal 23(a) at a low-voltage detector 23, a CPU 2 determines according to the condition of a starter switch 20 whether or not an engine is being started. A Flag A is set to 1 when performed and set to 0 while not, so that necessary data including the FlagA is urged to take refuge in a RAM 4. Next, the CPU 2 determines at every fixed period whether or not an ignition key switch 16 is off. When it is off, a FlagB is set to 1 after a predetermined period has elapsed and the necessary data is urged to take refuge in the RAM 4, then an electric source relay 19 is switched off. After it has been reset, therefore, the controller may in any case not judge that the electric source relay 19 has broken down unless the Flag, A, B both read zero, so that an initial setting of data within the RAM 4 due to low-voltage resetting during start of the engine is prevented.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To access at high speed by making nearly constant a signal propagation time after an output of a column data stream is activated before a read signal reaches a sense buffer array and shortening the time. SOLUTION: An external signal input/output pad array 11 is formed at a central part of a chip 10A, and memory circuits are formed symmetrically at both sides of the array. A column decoder array 16 and a sense buffer array 17 are arranged at a bank BNK0 with holding a memory core part of the bank BNK0 therebetween from a direction at right angles to a longitudinal direction of a sense amplifier array. The sense buffer array 17 is placed at the side of the pad array 11. The same arrangement as in the bank BNK0 is provided in banks BNK1-BNK3. Since the pad array 11 is arranged at the central part of the chip, higher-speed accessing is enabled under a good condition that a timing margin related to a signal propagation between each bank and the pad array 11 can be reduced.

IPC: G11B33/12
Filed: 1993-07-28
Abstract: PURPOSE:To provide an electronic instrument which facilitates maintenance and has reliability by providing an upper unit and the magnetic disk device unit or either thereof with an attaching and detaching mechanism. CONSTITUTION:An HDU 1 includes an HDD 11, a circuit board 6 and ad HDU side connector 7 At least either of the HDU side connector 7 and the circuit board 6 are half fixed to the HDU 1. The HDU 1 is connected and fixed by lever 2, positioning holes 13 and positioning pins 9. The mechanism to prevent the application of a stress on the circuit board 6, the HDU side connector 7 and the upper side connector 8 is constituted after connection. As a result, there is an effect of improving a maintenance characteristic by the HDU attaching and detaching mechanism. Since a lever is utilized for the attaching and detaching mechanism, operating force is lessened and since the impact, etc., by reaction of insertion and removal are not applied, there is an effect of improving the reliability. The HDD, the circuit board, the connector, etc., are included in the HDU and, therefore, the direct action of disturbance on the inside does not arise. Since the stresses are not held applied on the HDU side connector, the upper connector and the circuit board, there is no fatigue breakdown of creep, etc., and there is the effect of improving the reliability.

Title: Memory with decoding function
Inventor: HASHIMOTO YOSHIAKI
IPC: G06F12/00
Filed: 1990-07-13
Abstract: PURPOSE:To omit the unnecessary decoding circuits and input/output pins at the side of an LSI and at the same time to minimize the delay time by finding out a fact from the output signal of an output pin that the data which is read out in a memory read state is equal to the data that is previously written in a register. CONSTITUTION:A memory part data write grant signal is set at 0 and 1101 (H) is applied to a data input line 15. At the same time, a write grant signal 16 is set at 1 to a register 11 and 1101 (H) is written in a 1st word of the register 11. Then 1011 (H) is applied to the line 15 and the signal 16 is set at 1 again together with 1011 (H) written in a 2nd word of the register 11 respectively. An output signal 19 of a comparator 13 is set at 1 when an address 121 is equal to OOOB (H) and OOAO (H) respectively, and the signal 19 is transmitted to an LSI 30 and used there. Thus it is not required to provide any unnecessary logic circuit for decoding operations nor any input/output pin for the decoding signal at the side of the LSI 30.

Filed: 1992-06-20
Abstract: PURPOSE:To prevent erroneous focus pulling-in by providing a level comparing means and setting a comparison level higher than a level by the reflection of a medium and lower than the lowest level modulated by a track. CONSTITUTION:The reflected light quantity signal of the medium is received by a bisected photodiode 11, and a current signal is converted to a voltage signal by input amplifiers 21, 22 and inputted to a subtraction amplifier 12, an addition amplifier 13, and a focusing error signal FE is obtained from the amplifier 12 and a light quantity summing signal FO is obtained from the amplifier 13. A focusing point vicinity detection circuit 23 is provided with a level comparator 23a and the light quantity summing signal FO of the output of the amplifier 13 is compared with a reference voltage VSL1 and when the signal FO exceeds the reference VSL1, a focusing point vicinity arriving signal FOK is changed to an 'H' level. Then, by a CPU 24, it is detected that an objective lens is in the vicinity of the focusing point, and a pull-in operation starting command is issued. Further, since a slice level is set lower than the modulation by the track while controlling focusing, out-of-focus after normal pulling-in operation is detected.
