Abstract: PROBLEM TO BE SOLVED: To eliminate requirement of a power supply and a complex circuit by inserting a display apparatus that operates with current between one point on a detecting line and a trolley wire body, and operating the display apparatus with a current flowing to a wear point through the detecting line when the wear or the contact occurs. SOLUTION: A magnetic-inversion-type display apparatus 6 and a rectifier 7 are inserted between a trolley wire body 3 and detecting lines 4, 5 to construct this detecting device 1, and a trolley wire 2 includes the detecting lines 4, 5 insulating with the trolley wire body 3 in the wire body. A trolley power supply 8 is connected with a starting end of the trolley wire body 3, and the terminal ends of the detecting lines 4, 5 are mutually shortened. The magnetic-inversion- type display apparatus 6, when the wear or the contact occurs, operates with a current flowing to a wear point 9 through the detecting lines 4, 5, a magnetic force of an electromagnet rotates a disk, and color is displayed. Thus, simply by inserting the magnetic-inversion-type display apparatus 6 between the detecting lines 4, 5 and the trolley wire body 3, existence of the wear can be easily displayed.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To machine a workpiece with high accuracy without generating a streak (flaw) to a specific part of the workpiece surface while using a formed grinding wheel by polishing abrasive grains of a grinding wheel layer on the surface of the formed grinding wheel before grinding the workpiece so as to make the protruding height of the abrasive grains constant. SOLUTION: The position of a flaw generated when a workpiece is ground is the case of a protruding abrasive grain 13 existing in a grinding wheel layer 12 electrodeposited to a formed grinding wheel 101 is measured, and the existing position of the protruding abrasive grain 13 corresponding to the flaw is specified in the radial direction of a grinding wheel rotation axis 14 from the position relation between the grinding wheel rotation axis 14 and a workpiece rotation axis. A probe of a surface shape measuring device is disposed in a radial position where the protruding abrasive grain 13 exists, to circumferentially specify the position of the protruding abrasive grain 13, where the surface height of the grinding wheel layer is protruded. A polishing tool 35 is positioned to polish only the tip of the protruding abrasive grain 13 so as to be the same height as its periphery.  The protruding abrasive grain 13 is therefore eliminated, and the protruding height of abrasive grains on the surface of the grinding wheel layer 12 can be made constant.

Title: Gamme correction circuit
Inventor: SAGAWA KENTA
IPC: H04N5/202
Filed: 1993-10-14
Abstract: PURPOSE:To obtain a gamma correction circuit improving the S/N in the low luminance level of a video signal without the degradation of image quality. CONSTITUTION:In a switch 7, an input video signal and a band limit signal are supplied and a gamma correction is performed for the selection output signal of the switch 7. High-frequency components and a signal level are detected in a comparator 4 and a comparator 5, respectively. A logical processing is performed for this detection result in an AND gate 6 and an effective decision circuit 20 and is used for the control of the switch 7. Thus, when a condition for selecting a band limit signal as an input signal to a gamma correction part (a low luminance level and a little high frequency component) is decided, the precision of the decision is improved because the decision is performed not by a picture element unit but by a prescribed area. Therefore, the degradation of sharpness due to the selection error in a contour part, etc., can be prevented.

Title: Vibrating frame body for packing developer, transporting pallet, funnel, developer packing method and device
Inventor: FUJIWARA YASUO
IPC: G03G15/08
Filed: 1992-09-28
Abstract: PURPOSE:To provide the vibrating frame body for packing a developer which can rapidly and efficiently pack the developer at a high density. CONSTITUTION:The vibrating frame body A for packing the developer used for primarily packing the developer into a developer supplying container, then applying vibrations to the developer supplying container to lower the powder level of the developer, thereby secondarily packing the developer is constituted of a light metal alone. Since the vibrating frame body A for packing the developer is constituted of the light metal alone, the vibrations applied to the developer supplying container via the vibrating frame body A are hardly attenuated, and the self-excited vibration of the container is moreover added. The developer is thus packed rapidly and efficiently into the container with high density. Since the vibrations are effectively transmitted to the developer supplying container, the vibration time with the conventional container is drastically shortened and the cost of packing the developer is reduced.
