Title: Cap screw
Inventor: HANAWA KAORU
IPC: F16B33/06
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To simplify a cap screw in constitution in such a way that the thread of its shaft part is to be threadedly engaged therewith, and an opening part is to be blocked by the cap part of its head part, and prevent sealing performance from being degraded. SOLUTION: In this cap screw, a ring shaped thermal plastic elastomer (e) is projected out of the fastening seat surface (f) of a resinous cap part 1c for an oil level gauge to be mounted to an oil inspection hole 3 by means of two- tone color molding, and it is so designed that the elastomer (e) is fitted in the inside of a fitting recessed part 3p when a thread part (n) of a shaft part 1j is threadedly engaged with a screw hole 3i so as to be fastened, in this case, even if foreign matters such as refuse come in the fitting recessed part 3p, since the foreign matters are removed out while the elastomer (e) is also rotated together when the cap part 1c is rotated so as to be fastened, no foreign matter will be held in between the elastomer (e) and the fitting recessed part 3p, and sealing performance is thereby prevented from being degraded.

Abstract: PURPOSE:To obtain an ultra-narrow and thick metal film pattern by the life-off method by lowering light reflectivity of the metal intermediate layer surface existing between a first and a second resist film and forming a resist mask on the semiconductor substrate with high accuracy. CONSTITUTION:A first resist 2 is applied to a semiconductor substrate 1 and Al 3 is vacuum deposited.

Thereafter Al is deposited in the specified thickness on the second resist film 4 having the holes 5, and the resists 2, 5 are melted and removed. Thereby, the desired thick metal layer pattern in the fine width can be formed with high accuracy.

Abstract: PURPOSE:To operate a fringe electric field at the ending time point of transfer cycle, and improve transfer efficiency, by holding a voltage at an intermediate level for a specified period, from a high level, for each transfer cycle of transfer clocks, and changing the voltage to a low level. CONSTITUTION:An N-type semiconductor layer is formed in the whole region of a CCD transfer channel on the surface region of a P-type semiconductor substrate 1.

The voltage level of transfer clocks phi1-phi4 corresponding with the respective phases is set high when the potential of the transfer channel becomes deep, and set low when the potential becomes shallow. In each transfer cycle of each transfer clock, the voltage level is held, for a specific period, at an intermediate level between a high level and a low level, from the high level, and then changed to the low level. The above driving method is adopted.

IPC: G09G3/20
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To remarkably improve total picture quality and also to reduce the power required for sustenance pulses by adding a compensation pulse for reducing the turbidity of a display picture caused by a write pulse at the vicinity of the write pulse to eliminate or reduce the turbidity of the picture caused in a direction perpendicular to a screen. SOLUTION: The driving circuit of this plasma display is constituted so that a compensation pulse CP is added in the vicinity of a write pulse WP and in a direction different from the polarity of the pulse WP right after the pulse WP. Now, when the compensation pulse CP is not present, since a light emission output becomes PW to be increased and causes a turbidity. When the compensation pulse CP is present, and PW-PK=PK-PC, t2 -t1 =t3 -t2 =T are made to be satisfied in the circuit, the increased amount of a light quantity by the write pulse WP and the decreased amount of a light quantity by the compensation pulse CP cancel each other to become a light emission output PK on average.  Since the value of a time T is the order of 100μs at the greatest, the light emission output PK being the value completely averaged by the response of visual sensation is sensed to eliminate the turbidity.

Abstract: PROBLEM TO BE SOLVED: To minimize the transient current and torque at the time of closing an AC side switch by generating a voltage command value to be output from an inverter of the voltage having the same phase and amplitude as those of the induced voltage of a motor calculated from the output signals of a position sensor and a speed sensor after the start of the operation of the controller of an electric system.

IPC: F01N3/24
Filed: 1992-08-11
Abstract: PURPOSE:To suppress release of NOx toward the atomsphere by arranging an NOx absorbent which absorbs NOx when an air-fuel ratio of exhaust gas is lean and releases NOx when an oxygen density is decreased, making the air-fuel ratio be rich while releasing NOx when a load is low other than a rich operation area, and reducing it. CONSTITUTION:An exhaust port 8 of an engine main body 1 is connected to a casing 19 which houses an NOx absorbent 18 through an exhaust pipe 17. In the NOx absorber 18, for instance, potassium is held by a carrier such as alumina. The absorbent 18 absorbs NOx when an air-fuel ratio in a combustion chamber 3 is lean. When an oxygen density is decreased, namely lean degree of exhaust gas is decreased, the absorbent 18 releases NOx. Rich and lean conditions of the air-fuel ratio is controlled based on operation conditions through a correction factor K of a fuel injection time by means of an electronic control unit 30. After the air-fuel ratio gets rich, the rich degree is gradually decreased and a theoretical air-fuel ratio is kept. The absorbent 18 gradually releases NOx and reduction is sequentially performed, to suppress release of NOx to atmosphere.
