Title: Inspecting method of magnetic recording tapes
Inventor: SANBE YOSHIO
IPC: G01R33/12
Filed: 1978-05-31
Abstract: PURPOSE: To respectively identify permanent or temporary defect places while running the tape by obtaining the logical product and exclusive-OR of the signals of two recording-playback heads.  
     CONSTITUTION: A magnetic tape 8 is run forward. When the normal signal from a recording circuit 4 is recorded into this with recording and playback heads 1, 1' and is immediately reproduced, defect place detecting circuits 6, 6' generate defect signals respectively for the reproduced signals of the heads 1, 1' if there is any defect place in the tape. Since these two signals have a time difference based on the distance between the heads, the signal of the circuit 6 is put in a delay circuit 9 to match the times of both, after which their logical product is obtained in an AND circuit 10. Since the output thereof turns out that the defect was detected by both heads, it becomes the signal indicating the permanent defect place. On the other hand, when it is detected only by one head, no output is generated in the circuit 10 and the signal owint to the exclusive-OR from a coincidence circuit 11 is outputted and therefore this may be identified as a temporary defect place.

CONSTITUTION:The recessed parts 3 of a transparent intaglio 1 are filled with a viscous ink or pasty material 4 and thereafter the transparent intaglio 1 and printed matter 5 re overlapped so that the recessed part 3 face side comes into contact with the printed matter 5 can be seen through and the alignment of them can be conducted easily and accurately. An ordinary silk-screen printing ink, etc., can be cited as ink to be used. Also, e.g. glass flux paste, etc., can be cited as pasty material. The viscosity of said ink and pasty material is preferably 10,000-200,000cp. Then, pressure is applied from the surface side opposite to the contact surface side of said intaglio or printed matter by the method of pressure roller, etc., and thereafter both materials are separated so that printing is conducted by transferring said filler (i.e. ink or pasty material 4) in the recessed parts 3 of said intaglio 1 to the printed matter 5.

Filed: 1992-03-24
Abstract: PURPOSE:To secure running stability of a vehicle to be excellent even when an irregularity in a running road surface is large by decreasing drive torque when an acceleration degree of the vehicle exceeds a reference value, and decreasing the reference value more as the irregularity in the running road surface is larger. CONSTITUTION:In controlling drive force of a vehicle, an acceleration degree of the vehicle is detected by an acceleration detection means 100 first. Next, when the detected acceleration degree exceeds a specified reference value which is preliminarily determined, drive torque of the vehicle is decreased by a torque decreasing means 102. Irregularity in a running road surface is then detected by a road surface irregularity detection means 104. The reference value is controlled by a reference value control means 106 to decrease the specified reference value more as the detected irregularity is larger. Running stability of the vehicle can thus be secured to be excellent even when the irregularity in the running road surface is large.

Title: Surface grinding device
Inventor: MAEDA SEIICHI
IPC: B24B7/00
Filed: 1986-03-25
Abstract: PURPOSE:To prevent quality from deteriorating due to adhesion of abrasive or etching phenomenon by transferring a processed workpiece within a short period of time and washing the workpiece by transferring a pressure mechanism from a processing position to a washing area along rails in a straight line movement. CONSTITUTION:When grinding is finished, a pressure plate 12 ascends. In the middle of the ascent, a transfer cylinder 23 starts transferring a pressure mechanism 3. At the same time, washing agent is injected from an intermediate nozzle 34 and a sub-nozzle 32 to a workpiece being transferred. When the pressure mechanism 3 reaches a washing area 5, the pressure plate 12 descends to place a main block 14 on a receiving table 30, injection from the intermediate nozzle and sub-nozzles is stopped, and washing liquid is injected from a main nozzle 31. Since transferring the pressure mechanism 3 to the washing area 5 is performed in a straight line movement along rails 21, the transfer distance is short and its movement is performed smoothly within a short period of time. Accordingly, the workpiece finished with processing can be transferred within a short period of time and washed. As a result, quality can be prevented from deteriorating due to adhesion of abrasive or etching phenomenon.
