Title: Axle high in fatigue strength for railroad and its manufacture
Inventor: KURITA MASATO
IPC: C23C8/38
Filed: 1992-07-14
Abstract: PURPOSE:To inexpensively and easily improve the fatigue strength of an axle for a railroad. CONSTITUTION:(1) This axle high in fatigue strength for a railroad is provided by subjected to ion nitriding treatment, and is the one in which at least the fitted part with a wheel has a surface compound layer of 10 of 20mum thickness constituted of an Fe4N (gamma) phase and a diffusion layer having >=280 Hv maximum hardness immediately therebelow. (2) The method is to manufacture the axle for a railroad (1) by executing ion nitriding treatment at a treating temp. of 550 to<660 deg.C for 0.5 to 4hr. Since the hardened layer formed on the surface of the axle by the ion nitriding treatment is low in heat sensitivity and the fatigue strength of the member is not deteriorated even if it is heated, there is no need of paying attention to the rise of the surface temp. at the time of flaw grinding. Moreover, the axle is small in the friction coefficient with the wheel material, damage such as gnawing is hard to generate.

Title: Charging apparatus
Inventor: KIYOSHIGE YOSHIHARU
IPC: H02J7/04
Filed: 1989-07-19
Abstract: PURPOSE:To prevent insufficient charge by discriminating between removal of AC plug and service interruption through resetting of an apparatus to a state before charging operation, when the operating time of a third timer exceeds over a given period of time. CONSTITUTION:The time setting of a third timer 27 is not less than 1 hour and not more than several hours. When a plug is taken out or put in during rest time, etc., no-voltage is detected first through an AC detection circuit 23. Then, a third timer circuit 27 is started, and a first timer circuit 25 and a second timer circuit 26 are stopped temporarily. If no-voltage continues over the set time of the third timer circuit 27, the first and second timer circuits 25, 26 are reset to enable reception of normal and uniform charging switches 31, 32. The third timer circuit 27 is also reset and a charging controller 10 is completely reset to a state before operation. In case of service interruption, when voltage recovers and the operation of the third timer circuit 27 ends within the set time, charging operation is restarted. Thus, it is possible to prevent insufficient charging due to the confusion of service interruption with removal of AC plug.

Title: Electrooptic device
Inventor: KOBAYASHI HIDEKAZU
IPC: G02F1/1337
Filed: 1988-07-27
Abstract: PURPOSE:To increase the apparent opening angle in the same way as in case of diagonal vapor deposition and to improve contrast and transmittance by using a perpendicular treating agent for oriented films as a method for an orientation treatment of the liquid crystal of the electrooptic device formed by using the ferroelectric liquid crystal and combining the same with a rubbing method. CONSTITUTION:The perpendicular treating agent is used as the method for orientation treatment of the ferroelectric liquid crystal 5 and is combined with the rubbing method for the oriented film. The liquid crystal molecules tend to be oriented in parallel with substrates by the effect of the rubbing treatment and the liquid crystal molecules tend to be oriented perpendicularly with the substrates by the silane coupling agent treatment. The liquid crystal molecules are made to exist with a certain angle with the substrates by these two reverse effects. The layer in a smectic C phase inclines in the same manner as in case of diagonal vapor deposition if the liquid crystal molecules are subjected to such treatment on the upper and lower substrates. The apparent opening angle is increased and the contrast and transmittance are improved in this way.

Abstract: PURPOSE: To ensure an improvement of heat efficiency and reduction in the running cost by forming a warm water circulation circuit with a pump, an far-infrared panel, a temperature detector, and an auxiliary heat source and connecting the circulation circuit to a starting warm water supply source through a three-way valve. CONSTITUTION: A changeover valve 10. is opened upon starting of floor heating, and cold water in an far-infrared panel 1 is driven out to the outside with warm water pressure from a heat source, and instead warm water from the heat source is replaced in a line in the panel 1. After starting, temperature of a circuit is detected and when set temperature is reached, the three-way valve 3 is changed over to interrupt supply of starting warm water from a starting warm water supply source 2. The changeover valve 10 is closed, and the route is changed over to a warm water circulation circuit composed of an auxiliary heat source 4, a pump 6, and the far-infrared panel 1. Hereby, the warm water returned from the far-infrared panel 1 is auxiliary heated with the auxiliary heat source 4 and is circulated. Hereby, supply of warm water to the circuit may be only one time upon starting, and hence wasteful use of warm water is eliminated to improve energy efficiency.

Filed: 1990-07-17
Abstract: PURPOSE:To reduce burring when a smooth layer is formed on a color filter by beveling the respective sides of at least a transparent resin coated surface of the liquid crystal substrate as specified. CONSTITUTION:The substrate 3 which is 1.1 mm thick is beveled to CO.3 mm and the peripheral edge part of the smooth layer 4 is absorbed and stored in the beveled part of the substrate 3. Consequently, the smooth layer 4 with <=Rmax0.1 mum display roughness can be formed so that its peripheral edge part does not project from the liquid crystal substrate end surface. Consequently, dust due to blur chipping is not produced in substrate storage, substrate positioning, and bundling as postprocesses and the liquid crystal substrate from which defect generation factors are removed is obtained.
