IPC: H01L27/04
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide oscillation circuit and semiconductor integrated circuit which can shorten the transition time from a low-power consumption mode to a normal operation mode without making the circuit complicated. SOLUTION: This oscillation circuit is equipped with an inverter ceramic oscillator 1, an inverter 2, and a NAND gate 3. The NAND gate 3 outputs the output of the inverter ceramic oscillator 1 as it is in the normal operation mode and fixes the output logic in the low-power consumption mode. In the inverter ceramic oscillator 1, a clocked inverter 11 of large size and an inverter 12 of small size which are connected in parallel are provided. The inverter 12 is in operation at all times and the inverter 11 operates only in the normal operation mode. Consequently, the period that the inverter ceramic oscillator 1 requires to oscillate stably when entering the normal operation mode from the low-power-consumption mode can be shortened, and the power consumption in the low-power-consumption mode can be reduced.

Title: Liquid crystal display device and its drive method
Inventor: TERASAWA TAKESHI
IPC: G02F1/133
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To dissolve a shortage of a charging time at a polarity inversion time and to realize a wide view angle with a ferroelectric liquid crystal and an anti-ferroelectric liquid crystal by successively selecting plural scanning lines answering first and second display areas with a first pitch and a second pitch respectively different from each other. SOLUTION: A whole picture is bisected to an upper part area consisting of (n) pieces of scanning lines and a lower part area consisting of (m) pieces of scanning lines. In respective bisected areas, the order selecting the scanning lines is made different. For instance, in the upper part area, a jumping scan that the picture is updated in the ratio of one piece to three pieces is performed, and in the lower part area, the jumping scan that the picture is updated in the ratio of one piece to two pieces is performed. A whole pixels are updated with three pictures in the upper part area, and are updated with two pictures in the lower part area.  In such a manner, by quickening the rewrite of the whole picture with the jumping scan even when deviation is caused in the upper/lower lines, picture quality of an animation, etc., is more improved compared with the case that one frame is completed while sufficiently changing every one line and prolonging the updating time of a picture by providing a region where such a jumping scan is performed that the interval of scanning lines is widened.

IPC: F02M37/00
Filed: 1994-02-14
Abstract: PURPOSE:To provide a fuel feeder, by which full-tank control can be conducted even during feeding of a fuel. CONSTITUTION:A first negative pressure operating valve 12 which is operated by negative pressure to communicate a passage is disposed in the midway of a fuel gas introducing path 11 for connecting a fuel tank 10 and a canister 14 to each other, whereby during starting of an engine, fuel gas in the fuel tank 10 is supplied to the canister 14 by the first negative pressure operating valve 12. On the contrary, during stopping of the engine, the first negative pressure operating valve 12 is closed to stop the supply of fuel gas to the canister 14. During feeding of a fuel, air is supplied from an air introducing means 52 to the first negative pressure operating valve 12, so that the negative pressure is neutralized by the air to close the first negative pressure operating valve 12. Thus, the fuel gas introducing path 11 between the fuel tank 10 and the canister 14 is cut off so as to conduct the full-tank control for the fuel to the fuel tank 10.

Abstract: PURPOSE:To prevent fuel consumption from becoming worse and prevent knocking from occurring by arranging a valve member actuated according to gas pressures on a side surface of a rotor, between an oil passage and an oil jet passage. CONSTITUTION:An oil passage 13 is formed through an eccentric shaft 10 which supports a rotor 7.

Filed: 1989-02-20
Abstract: PURPOSE:To stably orient a high-polymer liquid crystal by utilizing a difference in coefft. of linear expansion to apply shearing stresses to the thin film of the high-polymer liquid crystal. CONSTITUTION:A dichloroethane soln. prepd. by dissolving the side chain type high-polymer liquid crystal is applied on a polyethylene terephthalate substrate 3 by using a wiper and is then dried to form the thin film 2. After a UV curing type multifunctional urethane acrylate resin is applied thereon, the coating is dried and is irradiated by UV rays, by which the coating is cured and a high-polymer film 1 is formed. The film is then heated to the glass transition temp. or above or the isotropic transition temp. or above and cooled. As a result, the shearing stresses are generated between the substrate and the high- polymer film by the difference in the coefft. of linear expansion between the substrate and the high-polymer film, by which the shearing stresses are applied to the high-polymer liquid crystal phase. The high-polymer liquid crystal is oriented in this way.
