Title: Liquid crystal display device
Inventor: ISHIHARA SHOICHI
IPC: G02F1/133
Filed: 1988-07-25
Abstract: PURPOSE:To suppress variation in flicker level due to variation in the temperature of a liquid crystal panel by providing a circuit part which adjusts the potential of a counter electrode so that the level of a leak current when the potential of a picture element electrode is larger than the potential of the counter electrode is equal to that when the potential of the picture element electrode is smaller than the potential of the counter electrode. CONSTITUTION:When the effective voltage applied to a liquid crystal layer is different between when the potential (a) of the picture element electrode is larger than the potential (b) of the counter electrode and when the potential (a) is less than the potential (b), the leak currents are different in value. For the purpose, the leak current when the potential (a) is larger than the electrode (b) and the leak current when the potential (a) is less than the potential (b) are detected and the potential of the counter electrode is so adjusted that those values are equal. Consequently, a symmetrical effective voltage can be applied to the liquid crystal layer and the flicker is suppressed for a long period without deterioration in display quality.

Title: Phase locked loop circuit
Inventor: YAMAZAKI TOYOE
IPC: H03L7/12
Filed: 1982-10-20
Abstract: PURPOSE:To facilitate an adjustment and to stable the working of a phase locked loop circuit, by using a loop amplifier of a phase locked oscillating circuit also as a reverse adder, transmitting a part of the output of the reverse adder through a BPF to apply it to an adder after reverse amplification and then constituting a search oscillation circuit in such a way. CONSTITUTION:The reverse amplification gain of a loop amplifier/adder 5 is decided by the ratio between resistors R5 and R7; while the gain of an adder is decided by the ratio between resistors R8 and R7. The output of the amplifier/adder 5 is transmitted through a BPF7 and amplified by a reverse amplifier for search oscillation to be applied to the adder 5. When the gain of this loop is set at >=1, the oscillation starts with the passing frequency of the BPF7. With synchronization of a phase locked circuit, a signal of an opposite phase to the adder 5 emerges at the output of an analog phase compensator 1. Then the gain of the adder 5 is reduced apparently, and therefore the oscillation is stopped.

Title: Illuminator
Inventor: KARASAWA JIYOUJI
IPC: G03B21/20
Filed: 1989-07-18
Abstract: PURPOSE:To eliminate temperature difference in the vertical direction in a light emitting tube and to eliminate difference in the vertical direction in optical characteristic by periodically rotating a metal halide lamp by means of a rotational means while it is lit. CONSTITUTION:In the metal halide lamp 1, the sealed part of a reflector 2 periodically rotates via a torque transmitting part 9 by means of a motor 10, and a cooling means 12 is adjacent to it by providing suction and ventilation holes on the side of the lamp house 5. When the halide lamp 1 is lit while it is periodically rotated, temperature difference in the vertical direction in a light emitting tube 16, which is caused by convection, is eliminated, and partial devitrification of a fused quartz does not occur. Since there is no temperature difference in the vertical direction in the tube 16, all metal halide in the tube vaporizes; since it is in dissociation and bonding/equilibrium conditions dependent on a temperature during arcing, the light emitting tube 16 emits light with entirely uniform brightness and color temperature. Thus, a projecting picture free of color shading can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an installation structure of Karman's vortex type flowmeter in which a fault due to adhesion of hair or the like is prevented. SOLUTION: The installation structure is applied to the Karman's vortex type flowmeter consisting of a vortex generating means 3 of a rod shape to cause Karman's vortex in a return pipe 13 as additional burning flow switch sensing a flow of bath hot water provided in the return pipe 13 forming an additional burning circulation pipe for a bath furnace and of a vibration sensing element 4 sensing vibration of water due to the Karman's vortex provided to a downstream of the means 3. The vortex generating means 3 is provided to the return pipe 13 obliquely so that the rod tip is directed toward the downstream from the upperstream of the return pipe 13 and there is a water flowing gap S between the tip 5 of the vortex generating means 3 and an inner wall 14 of the return pipe 13 opposite to the tip 5.  Even when hair or the like is going to be adhered to the vortex generating means 3, the hair or the like flows to the tip of the vortex generating means 3 along with the water flow and flows to the downstream of the return pipe 13 through the gap S. Thus, adhesion of hair or the like to the vortex generating means 3 is prevented thereby suppressing occurrence of a fault or the like in the flowmeter.

SOLUTION: A lining skin 3 is laid on the bottom of a hollow heel cap 1 having an upper part open. Also, an inwardly curved part is formed along an area from the open part of the heel cap 1 to the peripheral side 4 and bottom 4 thereof. When the heel cap 1 is used, the peripheral side 4 and the bottom thereof are pinched by using the fingers of either the right hand or the left hand, and the open part of the heel cap 1 is kept in contact with the heel of a dancing shoe. Then, the heel cap 1 is pushed upward from a lower position. Alternatively, the dancing shoe is put on and the heel thereof is stepped down, with the heel of the shoe positioned slightly inside the open part of the heel cap 1. The heel cap 1 is thereby attached to the heel of the dancing shoe. According to this construction, the heel cap 1 can be easily mounted or demounted, and easily handled. Also, the need of fixing the heel cap 1 with a tape can be eliminated. At the same time, the peripheral side 4 is curved, thereby eliminating a concern about falling out.
