Title: Commutator motor blower and electric cleaner
Inventor: MORISHITA KAZUHISA
IPC: H02K27/00
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To secure insulation between a fan side winding wire part and a load side bracket and to reduce windage losses which occur in the projecting and recessing parts of the winding wire part by covering the outer periphery of the fan side winding wire part of an armature by means of a windage loss reduction cover formed of an insulating material. SOLUTION: The outer periphery of a shaft 3 is covered from below a fan side bearing 4 of an armature 1 and a windage loss reducing cover 81 whose cross-sectional shape of a radical direction is circular, whose cross-sectional area of a circle is made to become larger gradually as it approaches the core 70 of the armature 1 and which is formed of resin in a trumpet shape is fitted to the outer periphery of a fan side winding wire part 80. Thus, windage losses caused the projecting and recessing parts of the fan side winding wire part 80 is reduced, and the efficiency of a motor part can be improved. Then, an insulating distance between the fan side winding wire part 80 and the fan side bearing 4 can be secured. When the windage loss reduction cover 81 is formed of a material whose thermal conductivity is high, such as silicon resin, the fan side wire part 80 can be cooled efficiently.

Title: Fabrication of photoelectric conversion element
Inventor: ASHIDA YOSHINORI
IPC: H01L31/04
Filed: 1985-08-07
Abstract: PURPOSE:To enable the improvement in photoelectric conversion efficiency by improving a short photocurrent and a curve factor by forming a P-type semiconductor thin film layer as nearly a protective layer on a base layer firstly by thermal decomposition technique. CONSTITUTION:After a P-type semiconductor thin film layer of 10-200Angstrom  is formed by the thermal decomposition of a mixed gas of a large degree silane gas SinH2n+2 (n is an integer as n>=2) and diborane, a P-type semiconductor layer is formed on the thin film by glow discharge decomposition of a mixed gas of a silane group gas and a III-hydride which is capable of formation of the P-type semiconductor layer. The large-degree silane is, e.g., disilane, trisilane, tetrasilane and etc., and the dilluting concentration is not specified, but usually 50% or more is preferable. Also, the III-hydride as a dopant for giving a P-type conductivity, more particularly diborane is dilluted generally in consideration of its toxicity by using H2 or an inert gas such as He, Ar and the 100ppm-10% concentration is preferable for use. A quantity of addition of diborane into silane is most preferably 1X10<-3>-0.01 of B/Si atomic ratio according to the characteristics of the P-type semiconductor film obtained by thermal decomposition.

Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent icing in a storage tank and to smoothly supply cooling medium such as liquefied nitrogen by shutting off the invasion of moisture into the tank. SOLUTION: A liquefied cooling medium in a storage tank 10 is pumped out via refrigerant supply tubes 12, 71 and supplied to a heat exchange room 20. A refrigerant return tube 72 is connected to the room 20, and the medium (gas) from which the heat of sample S is absorbed in the room 20 is again returned to the tank 20 via the tube 72. The pressure drop is eliminated by the return of the medium in the tank 20, and the liquefied cooling medium can be continuously pumped out. Further, the tank 10 is shut off from the atmosphere, and the invasion of the air containing moisture can be prevented.

Title: Display device
Inventor: NAGANO AKIHIKO
IPC: G02F1/13
Filed: 1987-07-10
Abstract: PURPOSE:To enable the display having a good contrast even if the incident luminous flux on a display element is weak by disposing a light source to the ends of two substrates and guiding light to a diffraction grating while the luminous flux from the light source is totally reflected between the substrates. CONSTITUTION:Part of the incident light on the display element 10 is diffracted in a diffraction grating part which is a display pattern in a display state. Of the diffracted light, the component having a large diffraction angle is jumped to the outside of the eyes' visual field and, therefore, the object light is visually recognized as if part of said light is attenuated. The display superposed on the object image is thus made. The display contrast of the display pattern decreases if the intensity of the object light is weak. The luminous flux from the light source 8 disposed at the end of the display element 10 is, therefore, projected to the display element 10 from the end thereof through a polarizing plate 9 and while the light is totally reflected between the substrates of the display element 10, the light is guided to the display pattern part. The decrease in the display contrast of the display pattern is thereby prevented.

Title: Testing device for watthour meter
Inventor: KAWAGUCHI JUNICHI
IPC: G01R35/04
Filed: 1987-07-13
Abstract: PURPOSE:To eliminate the need for calculation by a person and to improve test accu racy by comparing the counted value of output pulse from a watthour meter with a reference value. CONSTITUTION:A main circuit base arithmetic part 5 processes an instantaneous power value 1 from a power converter and a composite current transformation ratio value 2 set by a composite current transformation ratio setter and the arithmetic result is stored in an arithmetic value register 6. At the same time, the watthour meter starts integration with an AC input to generate a 1st output pulse after the start of a test. This output pulse is read in an integrating register 7 as an electric energy pulse 3 and the register 7 starts integration. Then when a 2nd output pulse arrives from the watthour meter as the pulse 3, the register 7 stops the integration, the electric power value of the register 7 at the stop of the injection is read in a test result register 8, and the reference value of the watthour meter per pulse which is set previously by a multiplication rate setter is stored in a reference value register 9 as a watthour meter multiplication rate value 4. Then an error decision part 10 compares the values of the registers 8 and 9 with each other and decides the test result. Therefore, there is no calculation done by a person, so no artificial error is made and the test accuracy is improved.

Abstract: PURPOSE:To facilitate selection of an observation visual field by discontinuing the movement of the visual field at the same time when the movement of a sample is stopped by deflecting electron rays, during the movement of a sample stage, by a degree corresponding to the direction and the speed of the movement. CONSTITUTION:When an input circuit 2 (operation button) is triggered at the point (A), a sample stage 16 is gradually accelerated by a command sent from a control part 3 and the position of the sample stage 16 changes. Next when the acceleration of the stage 16 is stopped and the stage 16 begins to move at a constant speed at the point (B), an observation visual field moves at a constant speed. Next when a stop signal is delivered from the input circuit 2 by pressing a stop button at the point (C), the stage 16 enters slow operation. In accordance with the slow operation of the stage 16, the speed of deflection gradually decreases and the deflected degree of electron rays gradually decreases. At the point (D), the movement of the stage 16 stops and the deflected degree of the electron rays becomes zero.
