IPC: H04L5/14
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To detect a signal rate that is used at a multiplex data rate by having a 1st receiver part operated when a 1st comparator detects a comparatively low data rate signal and having a 2nd receiver part operated when a 2nd comparator detects a comparatively high data rate signal respectively.

Filed: 1990-01-18
Abstract: PURPOSE:To excellently secure the image quality of the color of three systems while effectively restraining the color mixture and the contaminative development of a reproduced image by using toner having a different polarity in the case of forming the image. CONSTITUTION:A negative latent image Zn where the potential of an image part is lower than that of a background part is formed on a latent image carrier 1 by a 1st latent image forming means 2.

Title: Electrical insulating coating compound
Inventor: HOSOKAWA ETSUO
IPC: C09D5/25
Filed: 1981-01-21
Abstract: PURPOSE: An electrical insulating coating compound providing a film having improved appearance and characteristics without danger of explosion, obtained by using a specific glycol ether compound as a solvent.  
     CONSTITUTION: One or more glycol ether compounds (e.g., propylene glycol monophenyl ether, etc.) shown by the formula (R is lower alkyl, phenyl;  n is 1 or 2) containing a secondary hydroxyl group is used as a solvent. For example, this solvent is used in the preparation of a polyester resin type coating compound, etc.(preferably resin content of ≥70wt%), to give the desired highly concentrated electrical insulating coating compound for melt coating. When it is subjected to normal temperature coating as a solution type electrical insulating coating compound, the blending amount of the glycol ether compound is more than the above-mentioned case. If necessary, a curing agent, filler, etc. may be added to the solvent. The addition of distyrylxylene, etc. to the coating compound before the glycol ether compound is added to it is effective for preventing the bumping of the solvent.

Title: Grinding device
Inventor: IWASAKI HIDEKI
IPC: B24B47/12
Filed: 1991-01-25
Abstract: PURPOSE:To prevent overloading a motor and a control circuit, etc., therefor, and accomplish a grinding device with enhanced processing efficiency. CONSTITUTION:A grinder motor driving control part 3 rotates a grinder motor 2 at a constant speed. When the revolving speed of a work motor 5 attains the set value, a work motor driving control part 6 feeds the current value supplied, and current limiting control is performed so that this current value lies within the allowable range set by an allowable range setting circuit 9. When this is attained, the work motor driving control part 6 supplies the work motor 5 with an AC current in accordance with the AC signal set by an AC waveform forming circuit 10. This constitution prevents the motors 2, 5 and driving control parts 3, 6 from application of excessive load over the allowable level. Thus a grinding wheel 1 and a work 4 can be accelerated quickly, the grinding time be shortened, and the processing efficiency be enhanced.

Filed: 1983-01-19
Abstract: PURPOSE:To achieve a highly accurate flaw detection by a method wherein vibrators adapted to perform transmission and reception separately are so arranged as to allow entry into corners of an angular billet and an ultrasonic beam entered from the vibrators focuses at the incident point to the angular billet to enter corners of the billet. CONSTITUTION:When vibrators 3 and 4 are excited alternately by an electric means, ultrasonic beams 7 and 8 turned to sector-like beams 7 and 8 underwater due to a focusing effect of acoustic lenses 5 and 6. So, when entering into steel from a corner R of an angular billet 2, these ultrasonic beams 7 and 8 cross each other to make ultrasonic beams 7' and 8'. One of expanses of the beams 7' and 8' propagates along the surface of the angular billet 2 while the other thereof propagates toward the inside thereof 2 and hence, any defect (a) existing on the surface of the angular billet 2 and a layer near the surface is received again with the vibrators 3 and 4 as reflected wave and displayed on a Braun tube as defect signal.

Abstract: PURPOSE:To obtain a dividing output with any dividing ratio and output timing position by simple constitution by storing any data in a shift register, by conducting a drive with an input pulse, and by gating the input pulse with the output. CONSTITUTION:To shift register 1, a dividng ratio selected previously by inputs XO to XN of selector 2 and outputs YO to Y4 of selector 2 for positioning an output pulse are inputted in parallel by input strobe B. If one input pulse A is inputted in this state, the pulse appears at pulse output D as it is since AND gate 3 is open with output C of shift register 1 ''1''. Then, shift register 1 is driven at the trailing edge of input pulse A and its contents are shifted by one bit, so that ''0'' will be outputted to C. At this time, the value of output C at the front is supplied to contents Q0 of shift register 1, which become ''1''. Next, when 2nd input pulse A is supplied, input pulse A is inhibited from passing through since output C is ''0''. In this way, the pulse patterns of dividing outputs can be selected freely.
