Abstract: PURPOSE:To prevent picture quality in the peripheral part of a picture display area from being dropped and to improve sharply the reliability of a liquid crystal picture display formed by sealing liquid crystal between two bases by forming an opposite common electrode only in the picture display area. CONSTITUTION:Signal potential selected by an element 5 is impressed to a picture element electrode 4, a potential difference between the impressed potential and the potential of the opposite common electrode 1 is impressed to the liquid crystal 6 and the driving state of the liquid crystal 6 is changed in accordance with the potential difference to display a picture. Since the potential levels of the opposite common electrode 1 are different in the inside and outside of the picture display area, the driving states of the liquid crystal 6 are also different in both the areas and the liquid in the interface part of both the areas does not execute normal driving. Thereby, no electric field is impressed to the liquid crystal on the outside of the image display area and the opposite common electrode 1 is formed only in the image display area as the shown structure, so that the picture quality in the peripheral part of the image display area can be prevented from being dropped and the reliability of the device can be sharply improved.

Filed: 1983-12-19
Abstract: PURPOSE:To manufacture simply and easily high quality YN easy to preserve by nitriding lump metallic Y by heating to a specified temp. in an atmosphere consisting of NH3, N2 and H2. CONSTITUTION:Lumps of metallic Y having >=50mum size are charged into a vessel of a high m.p. metal such as Mo, Ti, Zr or Ta, and they are heated to 800-1,400 deg.C in an atmosphere of NH3, NH3+N2, NH3+H2, N2+H2 or NH3+ N2+H2 in a reaction furnace to obtain lump YN by a reduction nitriding reaction. Shavings obtd. by cutting an ingot of metallic Y are preferably used as the lumps of metallic Y because the shavings have a relatively uniform shape, cause hardly surface oxidation, and have sharp edges which accelerate the reduction nitriding reaction. YN obtd. by this method is in the form of lumps having >=50mum size and is hardly oxidized even in air, so it is easily handled and preserved.

Title: Inverter control apparatus
Inventor: YOSHIHARA SHIGEYUKI
IPC: H02M1/16
Filed: 1991-09-19
Abstract: PURPOSE:To prevent inflow of an excessive charging current, in a structure wherein a smoothing capacitor of power supply is sufficiently charged through a first relay through a resistor and then connected directly to the power supply through a second relay, by extracting a coil power source of the second relay from a capacitor and disabling operation of the second relay while the voltage is insufficient. CONSTITUTION:First, operation of a controller 8 is started to turn ON the transistor 9 for connection of a relay 2 to charge a capacitor 5 with a time constant determined by a resistor 3 and a capacitor. When the capacitor 5 is sufficiently charged, a transistor 10 is turned ON to connect a relay 4. Since the voltage of the capacitor 5 is almost equal to the voltage of a battery 1, a charging current when the relay 4 is connected is smaller and a trouble such as deterioration of operation life and burning of capacitor 5 is no longer generated. If it is attempted to previously connect the relay 4 due to malfunction of the controller 8, when a voltage of capacitor 5 is low, the relay 4 does not operate since the coil power source is obtained from the capacitor 5.
