Title: Exposure system
Inventor: HIKIMA IKUO
IPC: H01L21/027
Filed: 1987-03-03
Abstract: PURPOSE:To enable stable exposure with appropriate quantity of light for a long time by increasing or reducing the diameter of a laser light beam by monitoring the variation of the quantity of laser light from the set quantity of light according to the detected output of the laser light. CONSTITUTION:When laser light is transmitted from an excimer laser equipment 10, the laser light is detected by a photodetector 100 provided behind a reflecting mirror 42 and the information of the light is sent to a quantity-of-light monitor 110. When the monitored quantity of light by the quantity of light monitor 110 is less than a set value, a controller 120 sends an instruction to reduce the diameter of a laser beam to a beam diameter increasing or reducing unit 20 and the diameter of the laser beam is reduced according to the instruction. When the diameter of the laser beam is reduced, the density of the quantity of light is increased. When the quantity of light by the quantity of light monitor 110 is more than the set value, the diameter of the laser beam is increased by the beam diameter increasing or reducing unit 20, so the quantity of light is reduced.

Filed: 1980-04-10
Abstract: PURPOSE:To prevent a discharge current from being one-sided owing to the resistance of line W, by supplying the discharge current to all bit lines or dispersedly selected bit lines through a discharge current circuit provided to couples of bit lines. CONSTITUTION:Discharge current iD supplied to bit lines B0, B1- at the ON side of cells MC11 and MC12 of selected word lines W1<+> and W1<-> flows through the cells, and discharge current iD of bit lines at the OFF side flows through bit-clamping transistors Q7 and Q8. In the transient state when a selected word column is getting unselected, current iD flowing through the cells becomes the discharge current of capacity C0 contributing to lines W and contributes to discharge until the lines W reach a constant level. Thus, an increase in the read speed of RAM using I<2>L memory cells and the prevention of erroneous writing can be performed.

Title: Electric insulation composition and power cable
Inventor: TAKAHASHI SUSUMU
IPC: H01B3/44
Filed: 1988-03-02
Abstract: PURPOSE:To aim at improving insulation endurance of an insulator by using a polyolefin to which an antioxidant is grafted by means of an organic peroxide. CONSTITUTION:A polyolefin can be bridged by an organic peroxide, but when a specific antioxidant is coexistent, it is grafted to polyolefin chains antecedently to bridging. The antioxidants that are ready to be grafted such as thiobisphenol antioxidants or phenol antioxidants having vinyl base are used. Namely, the voltage withstand characteristic can be improved by suppressing acceleration of moving electrons within the crystal structure when insulation breaks as a result of more of less inhibition of polyolefin crystallization, and by suppressing acceleration of electrons due to aromatic rings having a resonant structure included in the antioxidant.

Title: Device for detecting abnormality of sensor
Inventor: ODA KAZUNORI
IPC: B60T13/52
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To surely judge the abnormality of a booster pressure sensor. SOLUTION: The abnormality is judged when the brake operation force is increasing in the operation of a brake operating member and the booster pressure is not increased in a state that the outflow of a gas to an intake side of an engine from a booster is inhibited (6). During the increase of the brake operation force, the booster pressure should be increased. The abnormality is also judged when the booster pressure is not decreasing in the non-operation in a state that the outflow of the gas from the booster to the intake side is permitted (5). During the outflow of the gas in the non-operation, the booster pressure should be decreased.  As the abnormality of the booster pressure sensor is detected not only by detecting the changing condition of the booster pressure detected by the booster pressure sensor, but also considering the operating condition of the brake operating member, the abnormality can be surely detected.

Abstract: PURPOSE:To obtain the subject non-pollution surfactant, excellent in biodegradability, having good surface activity, suitable for emulsion polymerization of synthetic rubbers or synthetic resins and useful as an antistatic agent, surface modifying agent or compatibilizing agent by addition thereof to various resins. CONSTITUTION:A nonionic surfactant expressed by formula I (R<1> and R<2> are H or 1-3C lower alkyl; R<3> is 4-30C saturated or unsaturated alkyl, aryl or aralkyl; (n) is 1-100). The aforementioned nonionic surfactant expressed by formula I is obtained by carrying out cationic ring opening polymerization of, e.g. 2-oxazolines expressed by formula II in the presence of a cationic polymerization initiator such as an alkyl tosylate, producing a compound expressed by formula III and then reacting the resultant compound with a mixture of a compound expressed by formula IV such as lauric acid with a base such as triethylamine in a solvent. Since the N-acylethyleneimine chain is a hydrophilic group and the acyl group of the ester is a hydrophobic group, the surfactant is rich in surface activity with biodegradability.
