Title: Nonlinear resistor
Inventor: HAYASHI MASAO
IPC: C04B35/453
Filed: 1988-09-13
Abstract: PURPOSE:To reduce the loss of the subject resistor to the utmost so as to improve the characteristics and miniaturize the resistor by preparing the raw material powder of the resistor by adding specific quantities of Bi2O3, Sb2O3, MnO2, Co2O3, Cr2O3, Al2O3, and P to a zinc oxide being the main constituent and burning the material after molding. CONSTITUTION:The raw material powder of this nonlinear resistor is prepared by adding specific quantities of Bi2O3, Sb2O3, MnO2, Co2O3, Cr2O3, Al2O3, and P to the zinc oxide being the main constituent. The adding rates of Bi2O3, Sb2O3, and MnO2 are respectively set to 0.2-2mol%, 0.2-3mol%, and 0.1-3mol%. Those of Co2O3, Cr2O3, and Al2O3 are respectively set to 0.1-2mol%, 0.1-2mol%, and 0.001-0.05mol%. The adding quantity of P is set to 0.009mol% of P2O5 equivalent. After preparation, the raw material powder is molded and burned. Since an appropriate quantity of P is added to the zinc oxide being the main constituent together with Bi2O3, Sb2O3, etc., the loss of the resistor can be reduced sharply. Because of the reduction in loss, the self-heat producing quantity can be reduced and the characteristics can be improved. At the same time, the resistor can be miniaturized.

Title: Valve timing control device for internal combustion engine
Inventor: WATANABE AKIMOTO
IPC: F02D13/02
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To suppress the rate of valve timing change in a variable valve timing control mechanism(VVT) at the time of steep acceleration, etc., and prevent generation of knocking in transient. SOLUTION: From the output signal θ1 of a crank position sensor 21 and the output signal θ2 of a cam position sensor 22, an ECU 30 corrects the change amount of the actual relative rotating angle on the basis of the engine speed change amount as the parameter related to the change amount of the actual relative rotating angle (θ1-θ2) in a variable valve timing control mechanism(VVT) 50 as the actual phase difference at present of the cam shaft 15 with respect to the crank shaft 11. When judgement is passed that the change amount of the engine speed is over the specified level and is in transient, generation of knocking in the internal combustion engine 10 is prevented without bringing about torque shortage at accelerating by introducing a proper correction so that the change amount of the actual relative rotating angle will not enlarge extremely.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a sharp image by delaying image data to be overlaid by an arbitrary time after detecting a transparent color to eliminate a position deviation at the time of detecting the transparent color. SOLUTION: A position detecting circuit 1 detects whether a coordinate position performing a display at present is a position where the image to be overlaid is to be ovelaid or not. A transparent color detecting circuit 2 detects whether the image data being displayed at present is of a designated transparent color or not. An AND circuit 3 ANDs detection signals of the position detecting circuit 1 and the transparent color detecting circuit 2 and when they coincide, the AND circuit 3 changes over the image data path of a changeover circuit 6 from an overlaying image data to the image to be overlaid. Moreover, a register circuit 5 sets how many dots of the image to be overlaid are to be delayed to transmit the setting information to a delay circuit 4, which, then, transmits the image data to be overlaid to the changeover circuit 6 by shifting them in a dot clock unit.

Title: Manufacture of semiconductor device
Inventor: INOUE MINORU
IPC: H01L23/52
Filed: 1987-09-17
Abstract: PURPOSE:To enhance the coating and flattening properties of a step part by a method wherein, when an aluminum wiring layer is formed by sputtering process on a primer substrate with the step part, the maximum heating temperature of the substrate is specified. CONSTITUTION:When an aluminum wiring layer is deposited by sputtering process, the maximum heating temperature of a primer substrate is raised up to the temperature exceeding 80% of the melting point in the composition of deposited aluminum layer but not exceeding the melting point. When the temperature of primer substrate during the sputtering process of the aluminum wiring layer is being raised, the aluminum wiring layer reaches the white turbid state but the deposited film thereof in the mirror state can be formed by further raising the temperature. The aluminum wiring layer in such a mirror state is homogenized correcting such defects as those developed in the white turbid state. Furthermore, due to the high mobility of aluminum atoms in such a high temperature, the coating property on a step part can be enhanced notably to flatten the step part.

Filed: 1982-12-28
Abstract: PURPOSE:To avoid an accident that a discharge lamp falls together with a ballast by providing a shell provided inside with a suspending section coupled with a place other than the stuck section with the ballast and/or a spacer. CONSTITUTION:When a shell 26 is coupled with a spacer 18, a ballast suspending section 30 is put in a condition supporting the face of a ballast core 35 on the discharge lamp side 1.

Abstract: PURPOSE:To run a magnetic tape stably at a high speed even when its amount is small by providing a wall surface material between the intake of a driving part and a slide piece on a side wall of a bin where the magnetic tape is stored, and moving the slide piece and varying the storage amount of the tape. CONSTITUTION:The flexible wall surface material 72 is provided between the partition wall 49 of the intake of the driving part and the slide piece 76 provided on the side wall of the bin 16 where the magnetic tape is stored. The magnetic tape 2 has a route shown in a figure and is run at a high speed by a capstan 4, pinch rollers 5 and 6, motor 13, etc., to preform its reproduction by reproducing heads 14 and 15, but when the amount of the tape is small, said slide piece 76 is moved according to the amount of the tape to feed the tape 2 into the intake along the wall surface material 72 all the time. Consequently, even when the tape amount is small, the inclination of the tape is prevented to perform the high-speed stable run.
