Title: Brake disk and its manufacturing method
Inventor: YAMADA TOORU
IPC: F16D65/12
Filed: 1978-06-30
Abstract: PURPOSE: By press-welding copper alloy surface plates to the both sides of a core material, which is an aluminum alloy, to obtain a triple-layered brake disk that is light and whose heat emissivity and antiabrasiveness are good.  
     CONSTITUTION: Surface plates 11a, 11b are formed on both sides of aluminum-alloy core material 10 by press-welding copper alloys, which are flux-treated beforehand, by such means as explosion-compression-welding for example. Then these are roll-shaped to the desired plate thickness, after which aluminum alloys and copper alloys are heated to the same temperature and the flux-treatment of aluminum alloy and ageing-treatment of copper alloy are done at the same time. Furthermore ageing treatment of aluminum alloy is done and brake disk 7 that is triple-layered is formed. In this case, as the heat conductivity of both aluminum alloy and copper alloy is great, they excel in heat emissivity and the copper alloy that forms surface plates 11a, 11b has good anti-abrasiveness so that a long longevity can be possible.

IPC: G01P3/489
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting apparatus by which the detecting precision of a wheel speed at a low speed can be enhanced at low costs. SOLUTION: A wheel-speed computing part (b) which computes a wheel speed on the basis of edges and on the basis of the time required for computing the edges is constituted in such a way that, when the wheel speed becomes a low speed and when no rise edge and no fall edge exist in a signal to be input to a recent control cycle, the wheel speed is computed in a supposition computing part (v) while it is supposed that an edge of a kind on standby at present is input in a present point of time and that one edge is input in the time required up to the present point of time after the edge of the kind on standby is input last. Thereby, when no edge is input in the present control cycle, the precision of the wheel speed can be enhanced more than in a case in which a wheel speed obtained in a previous control cycle is regarded as a present wheel speed.

Title: Inspecting method for circular object
Inventor: ASANO KENJI
IPC: G01B11/30
Filed: 1985-04-17
Abstract: PURPOSE:To detect with high accuracy microscopic defect of the peripheral part of a circular object by deciding the quality at every microscopic window which have been set along the outside periphery of the circular object. CONSTITUTION:A television camera 11 brings a circular object 1 to an image pickup and converts it to an electric signal. This signal is converted to a binary digital signal in an A/D converting part 12, and stored in an image memory 14. A feature extracting part 15 extracts various feature data of the object 1 from the memory 14, and a processor 16 executes an operation processing, based on it. A window generating part 13 sets a microscopic window 2 which has divided an annulus ring surrounded by two circles having each different diameter along the circular object, into plural parts at a prescribed angle, in accordance with an instruction from the device 16, and selects a feature data to be read out of the memory 14. In this way, whether the object is good or defective is discriminated by comparing an object area data of each window 2 obtained from the feature extracting part 15, with prescribed upper and lower limit values by the device 16.

Title: Circuit for discriminating streak-like defect
Inventor: IIDA AKIHISA
IPC: G01N21/89
Filed: 1988-04-01
Abstract: PURPOSE:To continue the sending of signals when streak shaped defects continue and to make it possible to discriminate the streak shaped defect and simple flaws, by keeping the integrated value at the level of the integrated value immediately before when a streak-like defect signal occurs. CONSTITUTION:The detected data which are binary-coded in a binary-coding circuit 12 are stored in a memory circuit temporarily. The data of a material to be checked is divided into small pieces. The data are inputted into an addition/subtraction control circuit 17 for every data cell at a specified period. Weighing is performed for the data. Thereafter, the data are integrated in an integrated value memory circuit 22. When the integrated value exceeds a specified value in a comparator 24, a streak-like defect signal is outputted. Then a gate circuit 28 is turned OFF through a NOT circuit 27. For a lane wherein the streak-like defect is present, the integrated data immediately before the output of the streak-like signal is kept. The output of the streak-like signal is continued when the streak-like defects continue after the streak-like defect signal is outputted. The discriminating detection between the streak-like defect and a simple defect can be detected highly accurately.

Title: Electrophotographic sensitive body
Inventor: MORIMOTO AKIYO
IPC: G03G5/05
Filed: 1987-03-31
Abstract: PURPOSE:To prevent degradation in the surface potential of a photosensitive body for positive electric charge consisting of a single layer having a dispersion type photosensitive layer by adding phenanthrene and phenanthrenequinone to said photosensitive body. CONSTITUTION:The phenanthrene and phenanthrenequinone are added to the photosensitive body for positive charge consisting of the single layer having the dispersion type photosensitive layer consisting of an electric charge generating material, charge transfer material and binder resin. The phenanthrene is an electron donative material and is capable of efficiently transporting holes in the photosensitive layer, The surface potential of said layer increases when said layer is subjected to a corona discharge. The degradation in the surface potential on repetition of copying is prevented by the synergistic effect of the electron donative property of the phenanthrene and the electron receptive property of the phenanthrenequinone when the phenanthrenequinone is added to the above-mentioned layer.
