Title: Refractory material for aluminum-lithium alloy
Inventor: OKA KAZUYOSHI
IPC: C04B35/10
Filed: 1991-11-25
Abstract: PURPOSE:To obtain stabilized refractory material by adding a specified amount of magnesia to alumina containing a certain amount of boric anhydride, thus being prevented from the penetration of aluminum-lithium alloy melt into the refractory material. CONSTITUTION:The refractory material for aluminum-lithium alloy comprises 5 to 20wt.% of magnesia, 0.5 to 5wt.% of boric anhydride and the residue of alumina. The addition of less than 5wt.% of magnesia is insufficient against the penetration of Li into the boundary areas of the textures, while over 20wt.% have the possibility of cracking because of its excessive increase in linear expansion coefficient. Boric anhydride mainly acts as a binder to harden the material into high stiffness, but it reacts with Li to form high-melting 2Li2O, B2O3 or Li2O, B2O3. These products migrate on the surfaces of the refractory material to form viscous, and thin coating films, thus protecting the material from the penetration of the aluminum-lithium melt.

Title: Liquid level controlling method
Inventor: ISHIWATARI SUSUMU
IPC: G01F23/00
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To continue liquid level control of a tank for a predetermined period even if an input value is unknown by comparing a sum of a virtual level obtained from an amount of change in the tank and a level immediately before breakage with a predetermined reference value in case a level meter breaks down. SOLUTION: In case a level meter 40 breaks down, a level input value immediately before the breakage is an initial value, and an amount of change per processing cycle is obtained from an open/close state of a valve 20 and a stopping state of a pump 30. A virtual level is obtained from the amount of change, and a sum of this with the initial value is compared with a predetermined reference value with which a tank 10 may not be full nor empty. Thus even if the input value of the level meter 40 is unknown, timing of opening/closing the valve 20 for feeding water can be determined. Therefore for a time until an error between an actual level and the virtual level is large and the tank 10 is either empty or full, level control can be continued.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a display substrate by providing a reloading means, which reloads a display substrate from a machining means for machining the display substrate, with a heating means which heats a part coming into contact with the display substrate. SOLUTION: A heating control means 109 which supplies electric power to the heater of a hand 102 consists of a power supply means and a temperature control means which calculates the heating value of the heater from its supply electric energy and limits electric energy supplied to the heater so that the heater temperature, i.e., the temperature of the heater reaches previously set temperature. This heater 102 generates heat based upon the current supplied from the heating control means 109 and conducts it to the whole hand 102. The temperature of the hand 102 at this time is set to temperature, etc., nearby the intermediate temperature between the room temperature and the temperature of a drying furnace 107.  Consequently, unevenness of the temperature distribution due to partial quenching of a glass substrate 106 at the time of contact (handling) can be prevented and accompanying curvature of the glass substrate 106 is prevented.

Abstract: PURPOSE: To form an image free from roughness and to improve the reproducibility of a dot image in a cleanerless developing device or in a dot image forming device by forming the developer with a spherical toner and a magnetic carrier and specifying the angle of repose of the developer. CONSTITUTION: A developer is conveyed to a developing part with a developer carrier, and the electrostatic latent image formed on the image carrier is developed in a developing magnetic field generated in the developing part by the developing magnetic pole of the magnet arranged in the developer carrier to form a picture. The developer consists of a globular toner and a magnetic carrier, and the angle of repose of the developer is controlled to <=30 deg.. A powder is allowed to free-fall from above the horizontal plane and conically accumulated, and the inclination of the inclined face is measured to obtain the angle of repose. The angle of repose is an index to the fluidity of the powder. When a high-fluidity developer having <=30 deg. angle of repose is used, a high-quality rustlingless image having a sharp tribodistribution is obtained because of the high releasability.
