Title: Deelectrifying roll and method for using it
Inventor: TAKASE TOSHIAKI
IPC: G03G21/00
Filed: 1990-05-31
Abstract: PURPOSE:To provide possibility of deelectrifying contacting parts directly and non-contact parts indirectly and also enhance the durability by using a conductive unwoven cloth layer in such a way lightly touching a charged object. CONSTITUTION:A conductive unwoven cloth 1 having naps 3 is wound on a conductive shaft 4 to form a conductive unwoven cloth layer, and therewith a deelectrifying roll 5 is constructed. Among static electricity lying on a charged object 6, the static electricity is the part touching this unwoven cloth 1 is released through the cloth 1. As for static elevtricity in the part not touching the charged object 6, on the other hand, lines of electric force are gathered in the spaces between the charged object 6 and the naps 3 on the cloth, as air exist there despite a very small amount, and an disequilibrium electric field is formed around there to produce dielectric breakage of the air, which generates corona discharge. Thus, deelectrification is made. With this unwoven cloth 1 having naps 3, the deelectrifying roll 5 shall be arranged in such a condition that only the facial part of the cloth 1 touches the object 6 lightly in the degree not generating distortion of the cloth 1.

Title: Eraser
Inventor: ARIYAMA ISAO
IPC: B43L19/00
Filed: 1995-05-02
Abstract: PURPOSE: To remove inconvenience of an omission of an eraser when the eraser is required by a method wherein an opening groove of such size that thickness of a pencil enters is formed in a part of the eraser, and the eraser is arranged at any position of the pencil by passing the pencil through the open groove. CONSTITUTION: An open groove 2 of suck size that thickness of a pencil enters is formed in a part of an eraser 1. Then, the pencil is passed through the open groove 2, and the eraser 1 is arranged at any position of the pencil. When the eraser 1 is used as a stopper for slipping of the pencil in that case, the eraser 1 is fitted to a tip side of the pencil, and the pencil is held from over the eraser 1. Then, since holding power is lightened by elasticity of the eraser 1, fatigue caused by writing can be reduced. Since the eraser 1 is used by inserting it into the open groove 2, it can be easily attached and detached. Further, since the pencil and the eraser 1 can be always integrally stored and used, there is no loss of the eraser 1 and labor for finding it can be removed.  When the eraser 1 is used under a state wherein it is fitted to a tip of the pencil, the eraser is always conveniently together with the pencil.

Title: Rotor housing of rotary piston engine
Inventor: KAKUWA SEIICHI
IPC: C23C8/32
Filed: 1978-11-17
Abstract: PURPOSE: To facilitate manufacturing of rotor housing of rotary piston engine and also to improve wear-resisting performance of the inner peripheral surface of the rotor housing where the housing is held in sliding contact with apex seals of rotor, by making the rotor housing with a single material of cast iron having a specific graphitic construction and applying soft-nitriding treatment to the inner sliding surface of the housing.  
     CONSTITUTION: Rotor housing 1 is made of spheroidal graphite cast iron or either one of A-type, B-type, C-type or D-type graphitic cast iron specified by ASTM, and Fe-C-N-type compound layer having a thickness greater than 1 is coated at least on the inner peripheral surface of the rotor housing 1 by way of soft-nitriding. Here, in case of using the A-type graphitic cast iron, graphite is distributed uniformly over the entire surface, so that it is suited for material of the rotor housing since it is superior in its surface roughness, machinability and polishability of the surface and in its slidability. In case of C-type, on the other hand, it is inferior to the A-type since fairly large particles of graphite are contained therein, but it does not offer any problem in practical use. Further, in case of D- and E-type, surface roughness is increased because of soft-nitriding treatment so that it takes long in polishing the surface, but they can be used also with no substantial problem.

Title: Optical semiconductor element
Inventor: UJI TOSHIO
IPC: H01S5/227
Filed: 1983-08-04
Abstract: PURPOSE:To control an optical output in a nonlinear shape in response to an optical input by a single element by laminating a plural layer of semiconductor layers having band gap energy larger than that of a light-emitting layer in the direction parallel with the laminating surface of the light-emitting layer. CONSTITUTION:An N type layer 22, a P type light-emitting layer 23, band gap energy Eg thereof is equal to Eg1, and a P type layer 24 are formed continuously on an N type InP substrate 21. A P type layer 25, Eg thereof is equal to Eg2 (Eg2>Eg1) and which has low carrier concentration, a P type layer 26, Eg thereof is equal to Eg3 (Eg3>Eg1) and which has low carrier concentration, and a P type layer 27, Eg thereof is equal to Eg4 (Eg4>Eg1) and which has low carrier concentration, are formed in succession. When currents are flowed through the optical semiconductor element in the forward direction, electron-hole recombination is generated in the layer 23, and beams are emitted. The threshold currents of laser oscillation are large at that time. When beams are projected from an incident port 29, on the other hand, oscillating threshold currents lower. Consequently, when currents are made constant and the intensity of input beams is changed, the intensity of output beams alters largely. Accordingly, a laser-oscillating output can be controlled in a non-linear shape to an optical input level.

Abstract: PURPOSE:To achieve a smaller size and a lighter weight facilitating the operation, by arranging a plurality of mirrors detachable at a fixed position so that the light emitted from a spectroscope is reflected with the mirrors sequentially to be incident on a light receiving element while they can be replaced with a sample. CONSTITUTION:Luminous flux emitted for a spectroscope through an emission slit 1 is made incident on a flat mirror MR1 at 45 deg., then on a flat mirror MR3 at 60 deg. through a mirror MR2 and the reflected light thereof is made incident on a photo detector D.

Title: Communication control method, communication system and electronic device used for it
Inventor: SATO MAKOTO
IPC: H04Q9/00
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To automatically display information by an information display signal generated by a prescribed electronic device on a monitor without needing preliminary preparation by the user. SOLUTION: A TV 11 recognizes an equipment configuration of the communication system consisting of the TV 11, an IRD 12, VTRs 13, 14 and a DVD 15. The TV 11 sends a NOTIFY command to other device being a component of the communication system to make a request to the other device to allow it to report a state change of an OSD. For example, in the case that a report of production of an OSD signal from the VTR 13 by a return of a CHANGED response, the TV 11 switches the input/output state of each device so as to give an output video signal of the VTR 13 to a display device. In this case, since the output video signal of the VTR 13 is fed to the display device, the TV 11 sends a CONTROL command used to switch the input/output connection to the IRD 12 according to need.
