Patent JP-H11273828-A (JP)
Title: Ignition plug and ignition and ion current detection device
Inventor: SATO YASUYUKI
IPC: G01M15/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To detect ions as an ion current by efficiently gathering the ions generated in a combustion compartment during combustion at a center electrode of an ignition plug. SOLUTION: A conductor part 28 of U-shape is adhered to a center electrode 23 of an ignition plug 21 by welding or the like, and the conductor part 28 is protruded below a grounding electrode 27 in a combustion compartment 29. After spark discharge has been generated between the center electrode 23 and the grounding electrode 27 when igniting, electric field directed from the conductor part 28 towards an inner wall of the combustion compartment 29 is formed in the combustion compartment 29 by applying a positive voltage to the center electrode 23, and thereby a negative ion generated during combustion is gathered by the conductor part 28 (center electrode 23), for detecting an ion current.  Since the conductor part 28 is protruded below the grounding electrode 27, the electric field directed from the conductor part 28 towards the inner wall of the combustion compartment 29 is not shielded by the grounding electrode 27 when the ion current is detected, and the electric field (lines of electric force) generated from the conductor part 28 can be distributed uniformly to an entire area in the combustion chamber 29.

Title: Preparation of artificial umeboshi (pickled plum)
Inventor: ADACHI NAOYA
IPC: A23L19/00
Filed: 1984-04-13
Abstract: PURPOSE:To obtain an artificial UMEBOSHI (pickled plum fruit) having the taste, flavor and appearance of natural UMEBOSHI, seasonable freely, and takable without removing the stone, by coating a formed article containing the pulp of pickled plum with an aqueous solution of alginic acid, etc., contacting with a solution of a coagulation agent, and drying the product. CONSTITUTION:The pulp of pickled plum, or its mixture with one or more components selected from seasoning, meat, egg, vegetable, food additive, thickener, etc. is formed to proper size and shape. The formed article is coated with an aqueous solution of alginic acid salt, carrageenan, pectin or furcelleran, made to contact with a solution of a coagulation agent to form an insoluble film, and dried. The solution of the coagulation agent is especially preferably an aqueous solution of calcium chloride. Although the time for forming the insoluble coating film can be shortened by the use of the solution of coagulation agent having relatively high concentration; however, the concentration of about 4-7% is preferable taking the washing process for the removal of the excess salt solution into consideration.

Title: Glass for germicidal lamp
Inventor: SUZUKI HIDETOSHI
IPC: C03C3/091
Filed: 1989-03-27
Abstract: PURPOSE:To obtain a glass transmitting ultraviolet ray of 253.7nm wavelength in high efficiency, resistant to the deterioration of transmittance caused by ultraviolet irradiation and having a devitrification temperature lower than the molding temperature by specifying the amount of each component, especially that of an alkaline-earth metal oxide. CONSTITUTION:The glass for a germicidal lamp is composed of 60-75wt.% of SiO2, 1-3wt.% of Al2O3, 3-8wt.% of Na2O, 5-12wt.% of K2O, 1-5wt.% of CaO+MgO, 11-20wt.% of BaO+SrO and 0-3wt.% of B2O3+P2O5, has a transmittance of >=70% at 253.7nm wavelength at a thickness of 0.7mm and causes <=6% of the lowering of the transmittance after continuous irradiation of ultraviolet ray for 100hr. When the amount of Na2O or K2O exceeds the upper limit, the deterioration of the transmittance becomes large. The devitrification tendency is increased by the use of CaO+MgO exceeding the upper limit. BaO and SrO prevent the lowering of the transmittance. Devitrification is liable to occur by the single use of BaO. When the sum of BaO and SrO is lower than the lower limit, the lowering of the transmittance is large and when it exceeds the upper limit, the devitrification is liable to occur. The content of BaO is preferably >=10% to effectively prevent the lowering of the transmittance. The devitrification tendency becomes remarkable when B2O3+P2O5 exceeds the upper limit.

Title: Production of iii-v group compound semiconductor crystal
Inventor: KASHIWA MIKIO
IPC: C30B29/40
Filed: 1988-03-30
Abstract: PURPOSE:To easily prevent ampoule crack by laying a glass cloth to the imposing part for a V group element of the device having the quartz ampoule which is disposed with a boat at one end and has the above mentioned imposing part at the other end. CONSTITUTION:Ga is put into the boat and the boat is inserted into the ampoule 1 at the time of growing the crystal of GaAs by, for example, a temp. grading method. The glass cloth 2 consisting of high-purity quartz fibers is laid to the other end of the ampoule 1 in tight contact with the inside wall surface of the ampoule 1 and As 3 is imposed thereon. A vacuum is maintained in this state in the ampoule and the ampoule is set in an electric furnace to allow the crystal to grow. Part of the As 3 sublimated at this time sticks to the surface of the glass cloth 2 in the region S and does not directly stick to the inside wall of the ampoule and, therefore, the ampoule crack by a difference in coefft. of expansion between the As and the ampoule is effectively prevented.

Title: Manufacture of amorphous silicon solar cell
Inventor: KITAMURA AKIHIKO
IPC: H01L31/18
Filed: 1980-06-03
Abstract: PURPOSE:To enhance conversion efficiency and to improve adhesion between an amorphous layer and substrate, by decomposing raw material gas in DC glow discharge at first and then in high frequency discharge, and depositing amorphous Si. CONSTITUTION:The amorphous Si which is formed by the DC glow discharge has more excellent adhesion with a substrate than that of Si formed by the high frequency glow discharge. But the conversion efficiency of the former is inferior to the latter. The adhesion between amorphous Si layers formed by both glow discharge methods is far better than the adhesion with the substrate. In this constitution, the solar cell employing the amorphous Si which is not separated can be obtained, and the conversion efficiency can be enhanced.

Title: Integrated radiator for semiconductor module
Inventor: JIEEMUSU FURANSHISU BAAJIESU
IPC: H01L23/473
Filed: 1992-03-31
Abstract: PURPOSE: To provide an integrated radiator including a common electrode for a plurality of semiconductor elements. CONSTITUTION: A support body 10 where a wave-shaped channel is provided and an upper electrode that is joined to the support in an electrically insulated state are included. The upper surface electrode is useful as a common module electrode 26 that can transfer heat to a final cooling medium without interposing a thermal barrier. The effective thermal coefficient of expansion of the support including the channel is maintained at a relatively low level by an upper covering plate 22 on the basis of copper constraint technique(CCT). Also, by allowing an upper electrode that is electrically insulated (but not thermally insulated) to form one portion of a fluid channel provided in the support, a thermal barrier that had existed before can be excluded when a semiconductor element 50 is directly mounted to a radiator.  Further, the weight of the radiator remarkably decreases due to the formation of the channel and at the same time a high reliability and connection property of a module can be obtained by using the CCT.
