Title: Hysteresis comparator
Inventor: MEGURO HIROSHI
IPC: H03K3/02
Filed: 1984-04-06
Abstract: PURPOSE:To simplify the constitution and to attain ease of circuit integration by eliminating the need for a current mirror circuit in comparison with a conventional circuit and forming a circuit decreasing the number of constant current sources and transistors (TRs). CONSTITUTION:Output TRs Q15, Q14 are turned off at a point A where an input signal E2 is applied to a terminal 3 is lower than an input signal (reference voltage) E1 fed to a terminal 4, a constant current i13 from a constant current source I13 is branched to the positions of a resistor R and a constant current source I12 via a diode D11. When the E2 is transited from the point A to a voltage B higher than the E1, the Q15 is changed from the off-state to the on-state, and the voltage difference between the E2 of the change point and the voltage E1, that is, R(i13-i12) becomes the hysteresis width 2. When the Q15 is turned on, the Q14 is also turned on, the i13 flows to the Q14 and does not flow to the D11. Further, since the D11 is biased reversely, it is turned off because the Q14 is turned on. When the E2 is lowered toward the point A, the Q15 is changed from the on to off-state, and the difference between the E1 and E2, that is, the Ri12 becomes the hysteresis width 1.

Title: Sodium-sulfur battery
Inventor: TOKOI HIROMI
IPC: H01M10/39
Filed: 1986-03-28
Abstract: PURPOSE:To prevent breakage of a battery caused by direct reaction of sodium with sulfur by arranging a means by which an anode active material and a cathode active material are separated. CONSTITUTION:A sodium discharge pipe 9 is arranged inside a solid electrolyte tube 1. An outlet of the discharge pipe 9 is opened in the upper aprt of a sodium drain container 10, and a sodium check-valve 11 is installed in the upper part of the discharge pipe 9. When a crack 12 arises in the upper part of the solid electrolyte tube 1, if the pressure on the sulfur side is high, sulfur enters sodium side through the crack, and sulfur reacts directly with sodium. By this direct reaction, temperature and pressure are rapidly increased, and sodium inside the solid electrolyte pipe flows out inside the sodium drain container 10 within several seconds by the increased pressure through the sodium discharge pipe 9. The discharged sodium can not flow back in the solid electrolyte again.

Title: Address inspection device
Inventor: AKAI SO
IPC: G06F11/22
Filed: 1989-03-20
Abstract: PURPOSE:To improve the reliability of a microprocessor by adding a simple inspecting circuit outside the microprocessor and detecting the trouble of the address output of the microprocessor speedily. CONSTITUTION:The microprocessor 1 outputs an address which increases, one by one, from its address bus as long as its operation is normal except during the fetching of a jump instruction, an interruption acknowledge cycle, and resetting. An address comparison part 2 compares the address of a last cycle with a current address under conditions where a function code indicates a program fetch so that the address output is normal when the both match each other and abnormal when not. Thus, the trouble of the address output or address bus is securely detected to stop the operation of the microprocessor immediately. Consequently, the reliability of the operation of the microprocessor 1 can be improved.

Title: Brake system for vehicle
Inventor: SHIRAI KENJI
IPC: B60T8/24
Filed: 1991-03-07
Abstract: PURPOSE:To improve facility for using a brake system of a vehicle by performing brake effect control in a way that the control is limited to a proper timing, in a brake system for a vehicle capable of effecting brake effect control wherein the brake force of a brake is controlled so that deceleration of a car body is adjusted to magnitude responding to a brake operation amount. CONSTITUTION:The pedal force of a brake pedal and deceleration of a car body are detected at S1 and S2. From the running speed, lateral acceleration, and the steering angle of a vehicle, it is decided at S3-S6 whether the lateral slip of a wheel is high. When the lateral slip is not high, brake effect control is effected at S7-S9 based on a pedaling force and deceleration. When it is high, a brake pressure having magnitude responding to a pedaling force is generated at S10 and S11.

Title: Lubricant for treatment of thermoplastic synthetic fiber
Inventor: YOSHIKAWA KIYOAKI
IPC: D06M101/16
Filed: 1988-03-23
Abstract: PURPOSE:To produce the subject lubricant emitting little fume, free from production of tarry substance and having excellent heat-resistance, by using a lubricant component consisting of a product having a specific kinetic viscosity and produced by reacting a specific ester compound having a specific kinetic viscosity with crosslinking agent in the presence of a radical generator. CONSTITUTION:An ester compound having a kinetic viscosity of 5-500cst at 40 deg.C is crosslinked with a crosslinking agent (e.g., a 4-30C compound having >=2 unsaturated bonds) in the presence of a radical generator such as an organic peroxide (e.g., alkyl peroxide) to obtain a compound having a kinetic viscosity increased to 1.1-50times the kinetic viscosity of the ester compound used as a raw material. When a lubricant for textile treatment containing said compound as a lubricant component is supplied in the form of e.g., an emulsion to a production process of a thermoplastic synthetic fiber, e.g., a thermal drawing or false- twisting process, it exhibits excellent heat resistance to prevent the formation of tar and the generation of fume and keeps the operation efficiency. The lubricant especially satisfies the requirement of the recent high-speed processing. The ester compound is e.g., tridecyl stearate.

Title: Manufacture of semiconductor device
Inventor: FUJITA KOICHI
IPC: H01L21/027
Filed: 1990-03-19
Abstract: PURPOSE:To enable a mask alignment with a high accuracy to obtain a fine semiconductor device with a high integration degree by detecting a minute deviation in the mask alignment through a moire pattern caused by the superposition of groups of annulus rings and by correcting the minute deviation. CONSTITUTION:A semiconductor wafer and a mask to be used in a photoengraving process are provided with alignment marks 2, 1 composed of groups of annulus rings and mask alignment is conducted by the superposition of the alignment marks. In this case, even if the marks 2, 1 in the group of annulus ring mask and the semiconductor wafer deviate from each other minutely, the deviation can be detected from the generation of a moire pattern by interference in both groups of annulus rings. Also, a deviation directed in any direction from the processed plane of the wafer can be detected by the use of the groups of annulus rings. Thus, the mask alignment with higher accuracy is made possible when the masks are adjusted so that this moire pattern disappears.

Abstract: PURPOSE:To effectively perform contour correction, by setting the through of the contour correction when a difference between a digital signal representing the light-and- shade of an original picture element and the digital signal representing that of a picture element before one is smaller than a prescribed value, and performing the contour correction when the former is larger than the latter. CONSTITUTION:A CCD line image sensor 1, by scanning an image such as a character, a graphic, and a fine line, etc., drawn on an original, inputs a picture signal corresponding to the image to an A/D converter 2. The A/D converter 2 converts the picture signal to the digital signal of 4 bits, and inputs it to a latch circuit 3, and also, inputs it to a ROM4, and the circuit 3 delays an inputted signal by one picture element, and inputs it to the ROM4. In other words, to the address terminals A1 and A2 of the ROM4, the digital signal representing the light-and-shade level of the original picture element and the digital signal representing that of the picture element before one are inputted, and when the difference between both picture elements is smaller than the prescribed value, the contour correction is set through. Also, when the difference is larger than the prescribed value, the contour correction is performed. In such a way, effective contour correction can be realized.
