Title: Liquid crystal display device
Inventor: NISHITANI TADATSUGU
IPC: G01R31/00
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the occurrence of shadowing phenomenon and to display without generating the unevenness of hue and brightness, etc., all over a liquid crystal panel by controlling a voltage value for impressing on a counter electrode based on the weak fluctuation of a voltage in the counter electrode which is generated by the load fluctuation of a picture element voltage on the same scanning line. CONSTITUTION:A voltage impressing line L1 and a voltage feedback line L2 are connected by a capacitor CF and a resistance RF which are arranged in parallel, and when the value of the resistance RF is changed, the feedback quantity from the voltage feedback line L2 to a voltage impressing circuit 12 can be changed. Then, even in the case that the ununiformity of the voltage is generated in the counter electrode 10 with the influence of the distribution of a signal voltage which is impressed on a signal electrode facing the counter electrode 10 with a liquid crystal panel interposed, the fluctuation is fed back to the voltage impressing circuit 12 by the voltage feedback line L2, and the amplification degree of an operational amplyfier OP1 is changed in a direction capable of fixing an impressed voltage. Thus, the shadowing phenomenon generated by giving the influence of the other part to the hue and the brightness of the picture element on a certain part on one scanning line can be prevented, so that the display can be performed without generating the unevenness all over the liquid crystal panel.

Title: Fixed-temperature heater
Inventor: YANO MASAFUMI
IPC: H05B6/54
Filed: 1987-12-25
Abstract: PURPOSE:To simplify the structure by constituting a dielectric substance with a ferroelectric substance having the reduced dielectric constant at the preset temperature. CONSTITUTION:A dielectric substance applied with the voltage via electrode plates 1 and 2 is constituted of a ferroelectric substance having the reduced dielectric constant at the preset temperature. When the temperature of the dielectric substance rises to this temperature by the application of the voltage, the dielectric constant of the dielectric substance 4 itself is reduced, the generated heat quantity by the induction heating is proportional to the dielectric constant of the dielectric substance, and the generated heat quantity is reduced accordingly. When the temperature of the dielectric substance 4 is decreased to the preset temperature or lower, the dielectric constant of the dielectric substance 4 is returned to the original state, the generated heat quantity is again increased, the temperature of the dielectric substance 4 rises again, and the dielectric constant is decreased at the preset temperature. The temperature of the dielectric substance is kept constant near the temperature at which the dielectric constant is decreased. No control system is thereby required at all, and a fixed-temperature heater with a simple structure is obtained.

Title: Electrode foil for electrolytic capacitor
Inventor: AKAMATSU TAKAYOSHI
IPC: H01G9/042
Filed: 1990-11-27
Abstract: PURPOSE:To obtain a large electrostatic capacity, to keep the electrostatic capacity of a desired magnitude even when an electrode foil for electrolytic capacitor use has been heat-treated or preserved for many hours under high-temperature and high- humidity conditions by a method wherein a metal thin film which contains carbon in specific quantities is used for the electrode foil. CONSTITUTION:A substantially flat and long aluminum-foil base body is loaded on a vacuum vapor-deposition apparatus which is provided with a long base-body running system. While the base body 18 is being run, e.g. a titanium ingot 30 is melted and evaporated and a titanium thin film in a prescribed thickness is formed on an aluminum foil at a prescribed vapor-deposition speed It is arranged that carbon atoms at 10 to 30% of the total number of metal atoms constituting the metal thin film are contained in the metal thin film. That is to say, in order to increase an electrostatic capacity, it is important that the carbon atoms at 10% or higher of the total number of metal atoms constituting the metal thin film are contained in the metal thin film. When their content is too large, the electrostatic capacity is reduced due to a drop in a dielectric constant. As a result, it is important that the content is at 30% or lower. Thereby, it is possible to obtain the title electrode foil whose stability of a characteristic is excellent, which is largely effective in increasing the electrostatic capacity and in which there in no danger of thermal damage at its manufacture.
