Title: Production of highly pure metal fluoride
Inventor: KOBAYASHI KENJI
IPC: C01D3/02
Filed: 1991-06-24
Abstract: PURPOSE:To produce a metal fluoride having a low vapor pressure in high purity. CONSTITUTION:A process for producing a highly pure metal fluoride, characterized by wet-purifying the metal in a solution state, preparing fluoride precipitates with a fluorinating agent, dehydrating and drying the precipitates, calcining the dried fluoride in a calcination step, subjecting the calcined product to an acid-dissolving step and subsequently preparing the metal fluoride in a dehydration treatment step. The high purification by the wet purification step, the removal of organic reagent residues by the wet purification step and the removal of oxide impurities by the dissolution treatment in the respective solutions of hydrofluoric acid, hydrochloric acid and nitric acid give the highly pure fluoride reduced in all of transition metal impurities, carbon impurities, and oxygen impurities.

Title: Charge controller for rechargeable battery
Inventor: OKUTO TADASHI
IPC: H01M10/44
Filed: 1990-07-06
Abstract: PURPOSE:To realize sufficient charging by making a judgment of approach to a fully charged state when a battery voltage at some timing is same as the battery voltage at next timing and stopping charging operation upon elapse of a predetermined time. CONSTITUTION:Charging operation is stopped as follows under high temperature environment where distinguished charging characteristics are not exhibited. In other words, when a battery voltage P obtained at a time point Ta is same as a battery voltage Q obtained at next time point Tb, a battery 1 reaches a substantially fully charged state. When a comparator 6 judges the state of P = Q, output at its output terminal 6b is switched to Low level. The Low level signal is fed to a flipflop 7 and the output thereof is switched to Low level. Consequently, a switch 3 is opened to stop charging operation.

Title: Spring vibration isolator
Inventor: NAKANO CHIKAO
IPC: F16F13/02
Filed: 1984-08-28
Abstract: PURPOSE:To facilitate the fitting of a vibration isolator and increase the vibration isolating effect of a coil spring by fitting the vibration isolator formed with a mesh-like tube and having a diameter slightly larger than that of the outer periphery of the coil spring around it. CONSTITUTION:A vibration isolator 2 formed with a mesh-like tube is fitted around a coil spring 1. The inner diameter d2 of the vibration isolator 2 is set slightly larger than the outer diameter d1 of the coil spring 1. If vibrations such as lateral deflection occur as the coil spring 1 is shrunk while in use, vibrations of the coil spring 1 can be quickly damped by the self-weight of the vibration isolator 2 and the friction resistance between the vibration isolator 2 and the coil spring 1. Accordingly, the vibration isolator 2 can be easily fitted to the coil spring 1, and the stable vibration isolating effect can be obtained.

Title: Device for irradiating uv light
Inventor: WATANABE YUKIO
IPC: F21V9/04
Filed: 1983-09-28
Abstract: PURPOSE:To enable reduction in the size of a filter and to increase substantially cooling capacity by disposing a lamp and a water filter for shutting off IR light respectively near the 1st focus and 2nd focus of a reflector having an elliptical reflecting surface. CONSTITUTION:Reflected light is condensed at the 2nd focus of an elliptical reflecting surface 2 as a lamp 3 is disposed near the 1st focus of said surface. The whole of the light reflected by a reflecting body 1 and the light which advances directly to a filter 4 out of the direct light arrive at the filter 4. IR light is shut off by the filter 4 and UV light transmits the filter and irradiates a surface 5 which is to be irradiated and is disposed forward. The whole reflected light can be condensed to the filter 4 in the above-mentioned way and therefore the filter 4 of a small size can be satisfactorily used even if the filter 4 of a small size can be satisfactorily used even if the filter does not cover the entire part of the aperture of the body 1. The concentrated removal of IR light from the reflected light is accomplished by passing cooling water in the central part of the filter. The cooling capacity to the surface to be irradiated is thus maintained high by the filter alone without using cooling wind in combination and therefore the construction is simplified.
