Title: Abnormal-condition controlling system for microcomputer control of vehicle
Inventor: NAKAMURA MITSUO
IPC: F02D45/00
Filed: 1981-12-28
Abstract: PURPOSE:To enable to control the engine operation in a stable manner without providing any special circuit, by employing such an arrangement that low-speed operation of an engine can be also detected by a trouble detecting circuit for a backup system attached to a microcomputer. CONSTITUTION:A pulse signal sinchronous with a reference crank angle signal is always produced from a microcomputor 1. Through detection of the pulse signal by a detecting circuit 3, low-speed operation and whether abnormal conditions due to the trouble of the microcomputor is caused or not can be known. In case that the operation is judged abnormal from the output signal of the detecting circuit 3, a backup circuit 2 is turned ON, and at the same time, the microcomputor 1 is reset for producing a control signal from the backup circuit 2. When the operation is rendered normal by the control signal, the backup circuit 2 is turned OFF, and at the same time, the microcomputor 1 is set again for producing a control signal from the microcomputor 1.

Title: Image forming device
Inventor: ITO MICHIO
IPC: G03G15/01
Filed: 1986-09-10
Abstract: PURPOSE:To preclude the color mixing and fogging of toner by carrying out bias exposure between a developing means and a developing means as the next stage, and setting the quantity of image exposure by an image exposing means larger than the quantity of exposure of a latent image forming process as a front stage. CONSTITUTION:The bias exposure is performed prior to a 2nd development to equalize the potential of a no-image part to the potential of a 1st latent image part. Consequently, there is no potential difference between the surface potential of a photosensitive drum 1 and a 1st latent image part potential, so toner of a 2nd color sticks on the 1st latent image part to cause color mixture and the developing bias voltage of a 2nd developing device 12 may have a normal value, so no reverse fogging is caused. Further, the quantity of light of a 2nd image exposure 11 is set larger than the quantity of light of a 1st image exposure 8, so even when the potential of the no-image part is held almost as high as a 1st visual image potential prior to a 2nd development, development contrast can be equalized between the 1st and a 2nd developing processes.

Title: Manufacture of semiconductor wafer, and grinding method and device for use
Inventor: HASEGAWA FUMIHIKO
IPC: B24B7/17
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To reduce variations in machining tolerance and to convert a batch processing system into a continuous processing system by causing a wafer cut on a thin disk to be passed between a pair of cylindrical grinding wheels each supported at both ends by bearings, flattening the wafer through simultaneous grinding of both sides, and polishing one or both sides of the wafer. SOLUTION: Backing rolls 12A, 12B energize and hold cylindrical grinding wheels 11A, 11B from their backs at equal pressures along their directions of axes, while being rotated in synchronization with the wheels, so even if grinding is performed to make large cuts in a single operation, deflection of the cylindrical grinding wheels against this grinding pressure does not occur; that is, grinding that can achieve very high flatness is made possible without the possibility of such grinding that the center of a wafer 13 is made thicker, and variation in grinding tolerance can also be reduced. As a result, two of conventional lapping and etching processes are reduced, and grinding that can provide large thicknesses and high flatness can be achieved even through one grinding process.
