Filed: 1988-04-08
Abstract: PURPOSE:To improve oxidation resistance and to improve C/N by forming a Tb-SiO2-TiO2 or Tb-SiO2-GeO2 as a 1st protective film on a transparent substrate. CONSTITUTION:The magneto-optical disk 5 is constituted by using the Tb-SiO2- TiO2 material or the Tb-SiO2-GeO2 material as the 1st protective film 2. The refractive index of SiO2 increases gradually with an increase in the ratio of the Tb to be added, but the absorption of light arises and the corrosion resistance lowers sharply if the SiO2 is added at above 50atom.%. The sufficient ratio of the Tb to be added is, thereupon, confined to about 20-30atom.% for the purpose of a protection effect to capture the free O or diffusing O atoms. and the TiO2 or GeO2 is added within the range where the degradation in characteristics such as absorption of light does not arise, by which the refractive index is increased and the enhancement effect to effect repetitive reflections within the protective film is enhanced. The oxidation resistance is thereby improved and the prolonging of the life is enabled. In addition, the value of C/N is sufficiently increased.

Title: Fishing weight having buoyancy by resistance of water
Inventor: SHOJI HIDEO
IPC: A01K95/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To solve such problem that a heavy weight is caught by the sea bottom or hooked to obstacles to lose a tackle because conventionally the heavy fishing weight has been used in order to cast the bait or the lure distantly. SOLUTION: The fishing weight is equipped with blades 2 on its upper part or flat projections are formed on the upper part or on the top edge of the weight so that the angle between the direction of the flat projections, when the weight is operated, to the horizontal line may exceed 0%o but is less than 90 deg.. Thus, when it is pulled, the weight receives the resistance of water so that it is floated up to reduce its hooking to rocks, seaweeds and the like. Even when a heavy weight is used, the lure or bait can be easily operated in the middle layer and the surface layer whereby the terminal tackle can be slowly sunk.  In addition, the gravity center of the weight is shifted to the reverse direction to the direction to which the weight is pulled or the position of the blades is allowed to move to the direction to which the weight is pulled whereby the force acts on the weight to that it may slide far away as a glider does distantly and the fish hit can be readily detected since the fishing line is not loosened even when wind blows strong and waves are high.

Abstract: PURPOSE: To efficiently elute a cationic substance contained in active carbon as an impurity, to prevent elution of the trace cationic substance from an AC tower and to recover a high purity water by bringing the active carbon packed in the AC tower into contact with a dilute hydrochloric acid having a specified concn., then washing the active carbon with an ultrapure water. CONSTITUTION: After removing an org. matter by passing at first a semiconductor washing waste water as downward stream from a piping 11 to AC tower 1, the waste water is allowed to pass an anionic resin (WA) tower 2 as downward stream from a piping 12 to remove acids such as hydrofluoric acid, nitric acid and sulfuric acid, and the treated water is discharged from a piping 13. In a recovering method of water from such a semiconductor washing waste water, before passing the semiconductor washing waste water, the active carbon to be packed in the AC tower 1 is brought into contact with dilute hydrochloric acid of 2-4wt.% concn., then washed with an ultrapure water.  In this way, the necessity of a cationic resin tower as an ion exchange device for removing an eluted cationic substance from active carbon is dispensed and a high purity water is recovered efficiently with only WA tower, that is, by using only AC tower and WA tower.

Title: Bonding method for semiconductor substrate
Inventor: FUJII HIROYUKI
IPC: H01L21/58
Filed: 1978-07-18
Abstract: PURPOSE: To obtain a good bonding with no bubble and others on a bonding surface by making a Au-Si alloy layer on a supporter bonding surface of a Si substrate and by laminating a Au thin film thereon and bonding the layer to the supporter through a solder.  
     CONSTITUTION: A Au plating is provided for the bonding surface of a Si substrate and the plated surface is heated up to 400°C approximately and a Au-Si alloy layer is provided. Thereafter, a gold plating film of 0.1 to 0.5μm is added thereto. Because the weakness would be caused in a thermal cycle by the difference of thermalexpansion between AuSi and Si, the Au-Si layer thickness is restricted less than 0.1μm. According to this method, a cavity may not be caused in the Au layer if the intervention of the Au into the Au-Si layer is occurred, the Au serves only for improving the applying with the solder. Therefore, a uniform bonding can be established and the thermal fatigue be completely removed.
