Patent JP-S6433924-A (JP)
Title: Semiconductor wafer
Inventor: KASAHARA JIRO
IPC: H01L21/265
Filed: 1987-07-29
Abstract: PURPOSE:To prevent channeling phenomena in ion implantation, to eliminate nonuniformity in the amount of ion implantation, shadow effects in selective ion implantation and the like and to make it possible to manufacture an element having a minute structure, a super high performance IC and the like, by using a semiconductor wafer having the crystal surface, which is inclined by a specified angle in the specified direction from a 100 face. CONSTITUTION:A semiconductor wafer having a crystal surface 12, which is inclined by 5-15 deg. in the specified direction from a 100 face (a), is used. It is practical that the inclined direction of the crystal axis from the 100 face is the direction of the crystal axis of + or -15-35 deg. from a 110 axis (b) on the 100 face. For example, when a GaAs field effect transistor is formed, the semiconductor wafer 11 having the wafer surface 12, which is inclined by theta=5-15 deg. in the direction of the crystal axis (c) forming + or -15-35 deg. with the 110 axis from the 100 face on said face, is cut out of an ingot 13. In this way, the channel effect in ion implantation can be suppressed, and the profile of the implanted impurities can be controlled highly accurately. Since an ion beam is vertically inputted with respect to the wafer surface, the uniformity in the amount of the implantation in the surface is improved.

Inventor: TANGE KYOICHI
IPC: H01M12/08
Filed: 1987-07-29
Abstract: PURPOSE:To obtain a battery with high energy density by providing an auxiliary battery with a separate reaction tank from a reaction tank between an electrolyte storage tank and the reaction tank. CONSTITUTION:A pump 52 feeding a positive electrode liquid to an auxiliary battery 44 is stopped when the charging of a main battery is started, zinc ions in the positive electrode liquid and a negative electrode liquid are unbalanced as the charging progresses, the operation of a positive electrode liquid circulating pump 52 is started when zinc ions in the negative electrode liquid are lacking, and the operation of the auxiliary battery 44 is started at the same time.

Title: Splash preventing matter for western style flush toilet stool
Inventor: OZAKI TOSHIHIDE
IPC: E03D9/00
Filed: 1994-08-15
Abstract: PURPOSE: To prevent splash of water at the time of evacuation by floating a splash preventing matter formed by a substantially spherical float, the outline of which is larger than a drainage port (suction opening) of a toilet stool on the staying water surface in the toilet stool. CONSTITUTION: At the time of evacuation in a Western style toilet stool, a splash preventing matter 1 formed by a substantially spherical float, the outline of which is larger than a drainage port (-suction opening), is floated on the staying water surface 2 in the toilet stool. If the outline of the splash preventing matter 1 is smaller than the drainage port, a string is fitted to the float to fix the float to a suitable place. Whereupon, excrement will not drop directly on the staying water surface 2, but strike on the splash preventing matter 1 to fall and sink in the water, so that splash is not caused. Subsequently, when washing water is let flow after stool, the splash preventing matter 1 is washed by itself while it is knocked around and sucked by a water current, and sunk under water with drainage.  When flowing water stops, however, the splash preventing matter is surfaced, and filth is completely washed away.

Title: Gas adsorbing element and gas adsorbing device
Inventor: OKANO HIROSHI
IPC: B01D53/26
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent the adsorbing capacity of a sheet material from being impaired by storing a honeycomb body to which a gas adsorbing and absorbind agent is affixed into a hollow cylindrical case having a vent hole while an abrasion countermeasure is adopted. SOLUTION: A hollow cylinder is constituted by a synthetic resin made case 1 which is excellent in heat resistance, chemical resistance, and abrasion resistance, a radial vent hole is formed in its plane parts at both ends and a sheet honeycomb body to which an adsorbing and absorbing agent of a gas is affixed is stored in its inside. A gas adsorbing element 6 is rotated by rotation of a geared motor 8, and an electric current is applied to blowers 10, 14 and a regenerating heater 12. The gas adsorbing element 6 sends treating air to a treating zone 11 while it is rotating, the moisture in the treating air is adsorbed into the honeycomb body to make dry air, and the honeycomb body having adsorbed moisture is regenerated by hot wind having passed through the regenerating heater 12 in a regenerating zone 13 following its rotation.  Though an end surface of the case 1 comes in sliding contact with a seal member 15, it is allowed to have a long life by selecting a material which is strong against abrasion. Thereby, the adsorbing capacity is not impaired to obtain a long life.

Abstract: PURPOSE: To obtain a depolymerized coal convertible to a light liquid product in a high yield with mild hydrotreatment by treating with a swelling solvent, after depolymerizing a coal by bringing a fine coal into contact with a hard acid in the presence of a soft base and extracting with a polar solvent.  
     CONSTITUTION: A coal is depolymerized by bringing fine coal particles of 10-1,000 μm particle size into contact with a hard acid (the heat of reaction with dimethylsulfid is 10-30 kcal/mol, e.g. methane sulfonic acid) at temperatures of 15-75°C for about one hour, in the presence of a soft base (the heat of reaction with boron trifluoride is 10-17 kcal/mol., e.g. ethylmercaptan) at temperatures of 0-100°C. The depolymerized coal is treated by extraction with a polar solvent (e.g. methanol) for removing a part of the hard acid, the soft base and mineral contaminants. And, then the depolymerized coal is treated with a swelling solvent having a density of 1.2-2.6 (chlorinated or brominated solvent, e.g. methylene chloride) for removing the mineral contaminants unremoved by the extraction.

Title: Device for checking upside and face side of paper
Inventor: MORI YOSHIMITSU
IPC: B41F33/00
Filed: 1985-08-31
Abstract: PURPOSE:To perform accurate examinations by detecting the density of a predetermined spot of a printed surface and the availability of printed matter for the comparison of densities of printed matters in synchronization with a timing signal transmitted when printed sheets are fed to a detection position, and display the comparison results. CONSTITUTION:Printed matter with reverse sides printed is delivered from a stack 8 and fed to a check position 12 through a conveyor 11, and brought to a stop by a stopper 13. While a timing signal is generated by a signal generation device 2, synchronized to a moment where printed matter is halted instantaneously, the reflection density of the reverse side of printed matter is measured by a density sensor 3. Then the density value measured is stored into a memory of a processor 5. When no printed matter is detected by a printed matter sensor 4, the measured value is cancelled. This measured value is processed by the processor 5 according to a program. When some measured value beyond the limits of a predetermined boundary value has been input, an alarm is sounded by an alarm device 17 or a notice is displayed on a display unit 6. The measured value is evaluated by the comparison for judgement of measured values of the first printed sheet with the next one. Thus correct checking of printed matter is assured.
