Patent JP-H01192220-A (JP)
Title: Driver circuit
Inventor: KAWAMOTO KOJI
IPC: H03K19/00
Filed: 1988-01-28
Abstract: PURPOSE:To reduce power consumption and to prevent malfunction of a digital integrated circuit by providing the 1st-3rd logic gates and supplying a drive signal respectively to two MOS transistors(TRs) with smaller ON resistance and larger drive capability than those of the 2nd and 3rd logic gates while being inserted between the 1st and 2nd power supplies. CONSTITUTION:Suppose that an input signal IN1 transits to a high logic level VDD, inputs of a NAND gate 3 go both to a high logic level VDp and its output signal (b) transits to a low logic level GND. As a result, since one of the NAND gate 3 goes to a low logic level GND, the output signal (b) transits to the high logic level VDD, the P-channel MOS TR 1 is turned off and the output signal OUT1 is kept to the high logic level VDD. Since either of the MOS TRs 1, 2 turned on through the transition of the output signal OUT1 caused by the transition of the input signal IN1 is turned off, the through-current I2 flowing through both the TRs 1, 2 is lost.

Abstract: PURPOSE: To efficiently treat noxious dust contained in waste gas so that it becomes innoxious, by arresting dust from the waste gas generated by a melting furnace, by the use of a dust collector, throwing collected dust ashes into molten slag produced in the melting furnace, and after that, solidifying it by a solidifying device.  
     CONSTITUTION: A substance to be treated 1 is thrown into a melting furnace 3 through a throw-in port 2 and is melted, but a part of a metal contained in the substance to be treated volatilizes and scatters, and it is discharged together with waste gas through an outlet 14. This waste gas is led to a dust collector 4 through an waste gas passage 11, and dust contained in waste gas is collected. This collected dust is thrown into a solidifying device 8 together with molten slag taken out from a take-out port 10, and is solidified. As for solidified slag 9, its volume is decreased in a state that a noxious substance has been enclosed, and said slag is disposed as it is. Dust, etc. generated by the solidifying device 8 are absorbed by a dust collecting hood 7 and are collected together with dust contained in exhaust gas, by the dust collector 4.

Filed: 1989-01-27
Abstract: PURPOSE:To reduce drift immediately after rise-up and to start measurement in a short warm-up time by providing a warm-up lamp and a warm-up lamp controlling circuit. CONSTITUTION:The output and the light emitting timing of a warm-up lamp 14 are controlled with a warm-up lamp controlling circuit 20. The intensity of the output light from the lamp 14 is adjusted within a range from the zero output to the output having the maximum rated current for a photomultiplier 16 with the circuit 20. The warm-up light having the intensity in the range from the 10 times the intensity of the measuring light to the intensity that can generate the maximum rated current in the photomultiplier 16 is inputted into the photomultiplier 16 for the specified short time before the start of measurement. Thus, the drift at the rise-up of the photomultiplier 16 is decreased, and the drift during several hours from the rise-up can be decreased. Therefore, the measurement can be started after the short warm-up time, and the efficiency can be improved.

Filed: 1989-01-26
Abstract: PURPOSE:To attain a stable information reading method by using a control mechanism to control the electric field which is applied to a stripe domain area and controlling the extending velocity of the domain tip. CONSTITUTION:A VBL 7 is already present at a tip 5 of stripe domains 2 and 3 in the initial state of a memory part domain, and a VBL pair 8 of data exists at a domain tip 6. When the pair 8 is read out, a bias magnetic field adverse to Hz is applied to a gate area to extend the tip 6. A groove 10 is formed in an area whose tip part is extended so that the domains can be easily separated from each other. A barrier is formed in an area held between the grooves 10 and a control mechanism is added so that only one type of domain can reach a domain cutting conductor pattern. The extending velocity of the domain tip part is depend on the number of VBLs existing at the tip part. Thus all domains arrived at a domain cutting part are cut to produce bubbles. Therefore a stable information reading method is attained by controlling the extended magnetic field of the tip 6.

Filed: 1993-01-13
Abstract: PURPOSE:To manufacture the cast parts whose surface layer part is made of high alloy by holding the temperature of the die at the prescribed calculated value, and forming the parts at the machining speed higher than the prescribed value. CONSTITUTION:The alloy stock in the solid-liquid coexistent condition is supplied to a die which is held at the temperature as indicated in the inequality, and the casting is formed at the machining speed of >=0.5m/sec. The alloy stock is Fe-C alloy or Al-Si-Cu alloy. When the material in the solid-liquid coexistent condition is formed, the part in the vicinity of the surface is made of high alloy, while the inside where the solid phase is mixed is made low alloy. That means, in the case of the steel where the material contains C, the surface layer part is made of steel containing more C, and the inside is made of steel containing less C. When the material is Al alloy containing Si and Cu, the surface layer part is made of Al alloy containing more Si and Cu, while the inside is made of Al alloy containing less Si and Cu. When the temperature of the die is low, only the liquid phase of the surface layer part is rapidly solidified to make high alloy.
