IPC: G07F13/06
Filed: 1989-10-16
Abstract: PURPOSE:To shorten a drink blending time by preparing a nozzle aperture area varying means and connecting an ice feeding line to a nozzle. CONSTITUTION:When a powder material is injected into a cup 8c by a vending command and the cup 8c is set up on the lower part of the nozzle 8, hot water pressured through a pressured hot water feeding line 9c is injected from the nozzle 8 into the cup 8c. At that time, a needle valve 11 is set up on a position where a gap between the outer face of the valve 11 and the inner face of an aperture part 8a is reduced by a driving means 13, the projection shape of injection is like an approximate ring and the injection water is radially discharged. Since a large injection area can be obtained, the efficiency of stirring is improved. Since dilution water and ice can be simultaneously injected from the same nozzle 8 in the case of producing a cold drink, a tasty cold drink reducing a temperature difference between the upper and lower parts of a cup can be obtained.

Abstract: PURPOSE:To block ultraviolet rays while keeping the ratio of passage of visible light high, by stacking an ultraviolet ray absorption film of a desired uniform thickness and a film having a uniform thickness and containing a substance having a desired refractive index, on the surface of an outer tube so that the films have a prescribed ratio therebetween. CONSTITUTION:An ultraviolet ray absorption film 7 is provided on the outside surface of an outer tube 2 containing a light emission tube 1. The film 7 is a mixed film in which a silicon oxide film containing a substance having a refractive index near that of the material of the outer tube 2 and a titanium oxide or cerium oxide film are stacked together at a content ratio of 5:1 therebetween. The thickness of the film 7 is 0.1mu or more. As for each of the films constituting the film 7, the outer tube 2 dipped in a solution of a metal alkoxide for the constituent film is pulled up out of the solution at a constant speed and baked to uniform the thickness of the constituent film. The refractive index of the film 7 is thus approximated to that of the outer tube 2. As a result, ultraviolet rays are blocked, while the ratio of passage of visible light is high.

Abstract: PROBLEM TO BE SOLVED: To prevent imperfect wire bonding, by completely eliminating a semiconductor thin film below an electrode which is to be bonded to a semiconductor thin film having a specific thinckness which is epitaxially grown on an insulating substrate and turned into a magnetosensitive layer. SOLUTION: An InAs thin film 4 of 0.5 (preferably 0.2-1.4)μm in thickness doped with Si is epitaxially grown on a semiinsulating GaAs substrate 5. In order to eliminate an InAs/GaAs interface modified layer 11 below an electrode which is to be bonded to the film 4, a necessary resist pattern is formed. By using it as a mask, etching is performed 0.7μm from the surface where copper (II) chloride, chlorine based etchant is used. Thereby the InAs/GaAs interface modified layer is eliminated. The cause of imperfect wire bonding is in the modified layer 11 having crystal defects which have generated mutual diffusion of the InAs/GaAs hetero epitaxial growth interface of a lower electrode to be wire-bonded. By eliminating the modified layer 11, generation of failure can be prevented.
