IPC: F16C32/04
Filed: 1987-07-23
Abstract: PURPOSE:To decrease a quantity of permanent magnets and to simplify the setting of magnetic field intensity by providing a superconductor in either an opposed part in a shaft side or a bearing side and a permanent magnet in the other. CONSTITUTION:A superconductor 5 is mounted to a rotary shaft 1, and a permanent magnet 4, which magnetizes the internal peripheral side to an N polarity and the peripheral side to an S polarity in the radial direction, is mounted to a bearing housing 2. By the constitution thus obtained, the permanent magnet 4 disables its magnetic line of force from advancing into the inside of the superconductor 5, lifting it thus supporting a load in the direction at a right angle with the shaft.

Title: Picture reader
Inventor: ICHIKAWA YUICHI
IPC: G06T7/00
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To enable precise color/black judgment by means of foreseeing color smear by discriminating whether picture data is a color or a monochrome based on distribution on a chromaticity drawing in the uniform color space of picture data. SOLUTION: An original loaded on original stand glass P is irradiated with light beams from a light source K and the reflected light is reflected on mirrors M1-M3 so as to converge them in a lens L. They are received by a picture read part 1 provided with a three line color image sensor. For processing a signal which is read by the picture read part 1, an input gradation correcting part 2 converts RGB output signals into signals proportional to lightness and a first color signal conversion part 3 converts the signals into L*a*b. A third color signal conversion part 10 calculates α'β' based on a a*b* in L*a*b* outputted from the first color signal conversion part 3. A color/black identification part 11 judges whether the original is the color picture or the monochromatic pictured by comparing α'β' with a threshold.

Abstract: PURPOSE:To prevent variance in contact pressure by arranging a contact spring which comes in contact with a specified point in a retracting position of a retractable antenna and on the side surface of the retractable antenna and by connecting the contact spring either to a metallic case or to a frame. CONSTITUTION:The end portion 1a of a rod antenna 1 is made slightly thicker in diameter than that of the main portion 1b of the rod antenna 1. The rod antenna 1 and its end portion 1a are guided with a rib groove 2 formed on a metallic case side. A projection 3 is provided at a position corresponding to a specified contact point of the end portion 1a in the retracted position of the rod antenna 1. A contact spring 4 is fit and fixed between the projection 3 and an upright wall 2c of the other side of the guide groove 2 or the opposite side of the projection 3 so as to hold the end portion 1a from both sides thereof. As a result, when the contact spring 4 is fit into the upright wall 2c, the end portion 1a of the rod antenna 1 is squeezed on both sides thereof between the projection 3 and the contact spring 4 with a specified contact pressure with the rod antenna 1 in its retracted position. This prevents the contact pressure from varying.

Title: Amorphous photovoltaic device
Inventor: WATANABE KANEO
IPC: H01L31/04
Filed: 1986-08-05
Abstract: PURPOSE:To spatially separate electrons from holes steadily for the suppression of their recombination by a method wherein depression in an energy band is made deeper on the side of incidence of light, rich in carriers, and shallower in the other side, not rich in carriers, located remote from the side of incidence. CONSTITUTION:On a transparent electrode 2 on a substrate 1, a p-type semiconductor layer 3, super-lattice lamination 4, i-type amorphous semiconductor layer 8, n-type amorphous semiconductor layer 9, and a rear-side electrode 10 are formed, in that order. The super-lattice lamination 4 is so doped that the quantity doped is less at locations farther from the side of incidence of light. With the lamination being designed as such, depression in an energy band is deeper on the side of incidence crowded with many carriers and is shallower at locations farther from the side of incidence, which ensures a steady spatial separation between electrons and holes. Further, with a proper migratory performance being available, their recombination may be suppressed.

Filed: 1982-10-21
Abstract: PURPOSE:To obtain the desired characteristics despite conversion into an IC, by using a signal to be integrated to the input of one side of a differential amplifying circuit with a capacitor connected to the other input terminal of said amplifying circuit and charging and discharging selectively the capacitor. CONSTITUTION:Transistors (TRs) Q21 and Q22 form a differential pair, and the base of the TRQ21 is connected to an external pin P11 of an IC21. While the base of the TRQ22 is connected to a capacitor C21 via an external pin P22. In such a constitution, the TRQ21 and TRQ22 are turned on and off while a signal to be integrated which is applied to the pin P11 is kept at a high level. For a selecting circuit 22, a contact (a) is connected to a contact (b) when the TRQ22 is turned on. Then the capacitor C21 is charged by a constant current delivered from a constant current supply circuit I22. While the TRQ22 is turned off to connect the contact (a) to a contact (c) while the signal to be integrated is kept at a low level. Therefore the charged electric charge of the C21 is discharged by the current flowing to the circuit I22. In such a constitution, a desired integration waveform is always obtained despite conversion into an IC.
