Title: Surface hardening material of cast steel parts, casting mold and surface hardening method
Inventor: MOTOKAWA HIROYUKI
IPC: B22D19/08
Filed: 1994-02-08
Abstract: PURPOSE:To form a stable hardened layer on the surface of parts to be cast and to have good wear resistance and toughness in combination by forming a surface hardening member contg. graphite powder on the inside surface of a casting mold, pouring a molten metal into the member and diffusing this surface hardening member into molten metal. CONSTITUTION:The surface hardening member 15 contg. the surface hardening material is formed on the inside surface part of the casting mold 10. The surface hardening member 15 is formed by adding a solvent to a surface hardening material consisting of a mixture composed of the graphite powder and WC powder, etc., and applying the mixture on the surfaces of the casting molds 11, 12, then drying the coating. The molten metal of a low-carbon steel, etc., is poured into the casting mold from a sprue 16. The molten metal comes into contact with the surface hardening member 15 and the graphite powder is dissolved into the molten metal by reacting therewith, thus rapidly diffuses into the molten metal. On the other hand, the WC powder diffuses into the molten metal as well by solutionizing part of its surface into the molten metal. Such diffusion is nearly completed by cooling and solidifying of the molten metal. The resulted cast steel parts have the high surface hardness and wear resistance and have the toughness in combination as the inside is a base metal having relatively low hardness.

Title: Fuel injection controlling apparatus for diesel engine
Inventor: HASEDA TETSUSHI
IPC: F02D41/40
Filed: 1983-03-02
Abstract: PURPOSE:To enable to control the fuel injection timing accurately without influence of aging, by calculating the actual injection timing from the actual lift of a cam disk used in an injection pump and a reference value of the injection timing obtained from the maximum value and the mnimum value of the lift of the cam disk. CONSTITUTION:In operation of an engine, the lift of a cam disk 1 used in a fuel injection pump is detected by a detector 2 and the output signal of the detector 2 is applied to a reference value determining means 3. In the means 3, a reference value fot the fuel injection timing is obtained from the maximum value and the minimum value of the lift of the cam disk 1, and an analogue signal for the output signal of the reference value determining means 3 is produced from a conversion circuit 4. Then, the analogue signal is compared as a threshold level with the output signal of the detector 2 in a comparison circuit 5, and the output signal of the comparison circuit 5 is applied to a control means 6 as the actual injection timing signal and compared with an aimed injection timing. Further, a timer 8 for controlling the fuel injection timing is controlled by producing a driving signal based on the deviation between the aimed injection timing and the actual injection timing.

Title: Infrared-ray image pickup system
Inventor: TERAOKA TOYOHISA
IPC: G01J5/48
Filed: 1986-02-18
Abstract: PURPOSE:To supplement the image of a defective element of an infrared-ray detecting element and to improve sensitivity by arranging plural arrays of infrared sensors successively in their scanning direction, and providing a memory for one array corresponding to each infrared-ray detecting element and a shift register on the output side of each memory, and summing up the outputs of the respective shift registers by adders. CONSTITUTION:As an incident infrared-ray image 16 is scanned and its instantaneous visual field is inputted from the 1st array of an infrared sensor, instantaneous visual field information begins to be stored in order from a shift register 13-11. Then when the 1st instantaneous visual field information is inputted to the 3rd array of the infrared sensor, the 1st instantaneous visual field information of each infrared sensor 3 is inputted to an adder 14 and added. Consequently, the defective element is supplemented and the sensitivity increases in proportion to the number of the arrays. When the number of infrared-ray detecting elements increases, the signal processing time of respective parts including a P/S conversion part becomes long. This is dealt with by dividing the number of infrared-ray detecting elements equally, providing the P/S conversion part, adder, etc., to each division, and synthesizing the outputs of the respective adders.

Title: Optical coupling semiconductor device
Inventor: YOKOGAWA TOSHIKI
IPC: H01L31/12
Filed: 1984-02-27
Abstract: PURPOSE:To increase the amount of vertically incoming beams and the adhesion of dice bonding by bending a lead end section formed by a metallic piece, on which a semiconductor light-emitting element is loaded, after a predetermined back region is thinned through etching, etc. and using the lead end section as an optical reflection wall. CONSTITUTION:The thickness of lead boards in the peripheries of light-emitting element loading regions in element loading leads for a lead frame 10 is formed thinly, and the thin sections are bent at fixed angles so that light emission from the light-emitting element is reflected to a light-receiving surface for a light- receiving element at a right angle. The regions such as prescribed back regions 15a at both ends sections of the lead frame are thinned through etching to thickness of approximately half the thickness of a frame board, and the thin frame pieces are used as metallic reflection walls 15. The lead frame pieces having such shapes are machined by a press by a mold having shapes corresponding to bending. Accordingly, the central section of the lead can hold flatness, and the amount of light vertically incoming into the light-receiving surface for the semiconductor light-receiving element can be increased while the adhesive strength of dice bonding can be augmented.

Abstract: PURPOSE:To make display characters easy to see and conspicuous by fringing only the right and lower sides of a display character. CONSTITUTION:A counter 1 outputs an address signal '1' when counting a horizontal synchronizing signal HS up to (n) and also generates an address signal '0' through a subtracter 2 at the same time. The signal '1' is inputted to a character ROM 3 and data WD on one line of the most significant digit is outputted with an address signal XA from a control circuit 4 and stored in a latch 5; and data '0' is stored in a latch 6 and the OR result between them is sent to a bit shifter 8 and a longitudinal fringing signal V0 is outputted. Then data on the 1st line of a character '1' is latched by a bit shifter 15 and further bit-shifted by the bit latch 16, and their outputs are ORed to output a lateral fringing signal H0. Consequently, a display character which is embossed in three dimensions becomes easy to see.

Abstract: PURPOSE:To prevent an output from being affected by the voltage fluctuation of a voltage source due to noise and the like, by forming an impurity layer under a load gate operating layer, and forming, under the load gate impurity layer, a potential well which does not fluctuate by the effect of external noise and the like. CONSTITUTION:A source voltage is applied between a first impurity layer 2 and a second impurity layer 4, and a specified voltage is applied to a semiconductor substrate 1. A constant voltage such as earth, which does not change by the effect of external noise and the like, is applied to a load gate 7. By applying the above unchangeable constant voltage, a potential well is formed under a load gate 7. This potential well is shallower than the voltage of the first impurity layer 2, and does not change by the effect of noise and the like. Independently of the ON-OFF state of an input gate, the value of the potential well is constant. Thereby, from the second impurity layer 3, an output is obtained which is not affected by noise independetly of the ON-OFF state of the input gate.
