Title: Power supply receiving unit
Inventor: UEDA HIROMI
IPC: H02H7/26
Filed: 1990-05-21
Abstract: PURPOSE:To notify disconnection of feeder and occurrence of overcurrent and to interrupt overcurrent automatically by monitoring current flowing through feeder of each system, upon disconnection of feeders of a plurality of systems on common earth side, and notifying detection of no current. CONSTITUTION:Upon disconnection of a feeder 73M on common earth side, no current flows through the feeder 73M and a corresponding no current detection circuit 11M provides a detection signal(earth) to a notify circuit 13. The notify circuit 13 notifies the fact in predetermined manner. When the feeder is removed for the purpose of repair of a power supply receiving unit, detection of no current or notifying operation is invalidated through a detection prohibiting circuit 15 being set externally thus avoiding useless notification. Consequently, when feeders of a plurality of systems on a common earth side are partially disconnected, disconnection and occurrence of overcurrent are notified and the overcurrent is interrupted automatically.

Title: Complex grinding method for ceramic parts
Inventor: ISHIDA MICHIYASU
IPC: B23H5/00
Filed: 1985-06-18
Abstract: PURPOSE:To enable easy and quick grinding of ceramic parts thus to reduce the cost by grinding a ceramic part secured with conductive material on the surface by means of a conductive grinding wheel while applying voltage between them. CONSTITUTION:A grinding wheel 1 will rotate under on-condition of power source 7 and advance while contacting against the surface of work 4 to perform normal grinding at the portion 2. Since nickel 5 is secured to the surface of work 4, power is fed to the work 4 flow current between the grinding wheel 1 and work 4 at the conductive section 3 to increase the temperature locally thus to electrolyze the surface of work 4 and to lower the strength of work 4. Consequently, the grinding speed is increased by said portion 2 to drop the work chip clogged at said portion 2 thus to enable efficient grinding. Since grinding, electrolysis and discharge are performed in complex, ceramic part can be grinded easily and quickly resulting in reduction of manufacturing cost.

IPC: H01L23/427
Filed: 1989-05-26
Abstract: PURPOSE:To reduce a waiting time at the time of starting a computer by using a flow liquid film evaporator for the evaporator of a refrigerating cycle. CONSTITUTION:The evaporator 6 of the refrigerating cycle is set to be the flow liquid film type evaporator.

Abstract: PURPOSE:To obtain a jig for firing having a coating which is excellent in heat stability, capable of use over a long period of time, and does not react with fired objects by laying on the surface of an alumina-based substrate a layer consisting of an yttria-stabilized zirconia-based material and a layer consisting of a calcia-stabilized zirconia-based material in a multilayer structure. CONSTITUTION:The subject relates to a jig used for firing functional ceramics such as a ceramic capacitor. The jig is formed by laying on the surface of an alumina-based substrate a layer consisting of an yttria-stabilized zirconia- based material and a layer consisting of a calcia-stabilized zirconia-based material in a multilayer structure. In the alumina-based substrate it is preferable for the alumina content to be, for example, 75wt.% or more and for the rest of the material to consist mainly of, for example, silica. Between the zirconia- based layers, for example, layers of mixtures of the two zirconia-based materials can be introduced in a structure of gradient constitution. The constitution mentioned above enables obtaining a jig for firing having a coating which is excellent in heat stability, capable of use over a long period of time, and does not react with objects subjected to firing.

Title: Production of silicon
Inventor: TANABE YASUO
IPC: C01B33/035
Filed: 1985-06-17
Abstract: PURPOSE:To produce high-purity silicon at a high speed and low cost compared with the process using electric power, by generating a flame of silane and chlorine, thereby precipitating fine silicon crystals. CONSTITUTION:Silane 3 and chlorine 4 are properly preheated if necessary and burnt with the burner 2 to generate the flame 10 of SiH2-Cl2. The temperature of the flame is raised to >=1,000 deg.C, preferably >=1,200 deg.C by the heat- generation. Th fine crystals of silicon produced from the flame are attached and deposited to the tip end of the starting material 5 connected to the rotary pulling up apparatus 6 to form a polycrystalline silicon 7. The starting material is pulled up under rotation by the rotary pulling up apparatus 6 corresponding to the growth of the polycrystalline silicon 7. The process of the present invention gives remarkably high rate of production of silicon and enables the production of a large-sized polycrystalline silicon easily at a low cost compared with the process using electric power. Since hydrogen is not used in the above process, the production cost can be further reduced and the intrusion of impurities of hydrogen into the product can be prevented to improve the purity of the produced silicon.

Title: Manufacture of synthetic resin cylindrical porous body with block cap
Inventor: WATANABE TAKAYUKI
IPC: B29L31/14
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To efficiently seal the end face in a solidly airtight manner without the necessity to perform a process such as adhering or fusion-bonding by setting a premolded block cap on the bottom face of a mold for sinter-molding a porous body, then charging plastic powder on the block cap and heating the plastic powder in such a state that the mold is filled with the plastic powder. SOLUTION: The outer part 1 of a mold for molding and its bottom part 3 are assembled, then a premolded block cap 5 is set at the bottom face part of the mold, and the inner part 2 of the mold for molding is introduced to the inner face of the block cap 5 in such a manner that the inner part 2 is caused to stand upright to make a gap formed by the outer half 1 and the inner half 2 uniform. The gap formed by the outer half 1 and the inner half 2 is filled with the plastic powder 6, and the mold is heated with an upper lid 4 set in place to sinter-mold the plastic powder. Thus the synthetic resin cylindrical porous body with the block cap 5 which assumes such an overall shape as to have the block cap 5 fusion-bonded to the end face of the synthetic resin cylindrical porous body, is obtained by releasing the moldings.  In addition, the block cap 5 is molded of a material which is highly compatible with the porous body so that the block cap 5 is firmly fusion-bonded with the porous body.
