Title: Liquid prism
Inventor: OTAKI MASARU
IPC: G02B5/04
Filed: 1992-04-07
Abstract: PURPOSE:To prevent an image from being distorted owing to a liquid prism by reducing the vertical temperature irregularity of the liquid in the liquid prism and making the refractive index distribution uniform. CONSTITUTION:On the 1st incidence surface 6a of a prism container 6 filled with liquid, a heat absorbing member 13 is provided on the lower part of an unnecessary-light irradiating area S between circles A and B irradiated by a light source 1.

Title: Safety device having operating state detection function
Inventor: OTA SHOGO
IPC: H04B3/46
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To electrically detect the operation of a safety element to transmit it to the outside and to collect information from a remote place by detecting the charging current of a capacitor which is always charged and also discharges when a switching element is turned on. SOLUTION: A capacitor C2 is always charged by DC voltage E1 and therefore discharges when a thyristor is turned on. The discharged current of the capacitor C2 flows to a closed circuit including the thyristor. When the discharged current is reduced less than the thyristor holding current, the thyristor is turned off. However, the current charged by the voltage E1 flows to the capacitor C2. Thus it is possible to detect that the abnormal voltage is applied to a communication cable 101 or 102 and therefore an arrester A1 or A2 operates by monitoring the charging current of the capacitor C2, i.e., the current flowing to a detection terminal AL from a remote place.

Abstract: PURPOSE:To realize the stabilized vibration control work even after a long term static condition by arranging the electroviscous gel between plural electrodes airtight, and bonding a body, of which vibration is to be controlled, and a mass body through an elastic body and a frame. CONSTITUTION:Under the condition that an outer frame 2 is connected to a body A, of which vibration is to be controlled, and an inner frame 3 is connected to a weight M respectively, the body A, of which vibration is to be controlled, is vibrated. At this stage, the weight M and the inner frame 3 work as a mass body supported by a deformation part 4. At this stage, in the deformation part 4, shearing deformation is generated mainly in an upper elastic member 40, a lower elastic member 41, electroviscous gel 43a, 43b, 43c, 43d. As the voltage to be applied between the electrodes 42a, 42b, 42c is increased, the deformation resistance of the electroviscous gel becomes higher. As a result, a resonance frequency of an auxiliary vibration system, which is formed of a mass body M and the deformation part 4, rises. Consequently, the resonance frequency of the auxiliary vibration system can be controlled by changing the voltage to be applied to the electrodes.
