Inventor: MURAKAMI NOBORU
IPC: H01L21/68
Filed: 1991-09-27
Abstract: PURPOSE:To reduce the vibration and impact to be applied to a material to be conveyed and to allow a stepout to scarcely occur in a motor by coupling moving elements by using two linear motors, performing a conveying operation by the motor for driving based on a cam curve and controlling to feed back the motor for generating a conveying power.

Title: Electrophotographic device
Inventor: YAMAGUCHI MAKOTO
IPC: G03G21/06
Filed: 1988-11-01
Abstract: PURPOSE:To minimize the winding of recording paper onto a photosensitive drum by using toner electrified to the same polarity as that of the surface of the photosensitive drum and cleaning the photosensitive drum after a static electricity discharge lamp discharges the photosensitive drum after transfer. CONSTITUTION:The toner electrified to the same polarity as that of the surface of the photosensitive drum 2 is used, and the discharge lamp 13 discharges the photosensitive drum 2 after transfer following which the photosensitive drum 2 is cleaned. Since the discharge lamp 13 is positioned between the recording paper 1 and the cleaning device 5 under this constitution, the discharge lamp 13 discharges the surface potential of the photosensitive drum 2. Consequently, the winding of the recording paper 1 onto the photosensitive drum 2 can be minimized. The discharge lamp 13 is away from an electrifier 9 over the cleaning device 5, and therefore the electrifier 9 never develops defective electrification owing to light from the discharge lamp 13.

Abstract: PURPOSE:To shorten a print pretreating time by so controlling first and second moving means as to move a printing head to the vicinity of the print starting end position of next printing line data without stopping the head after the print of preceding printing line data is finished. CONSTITUTION:A printing operation controller has first moving means 3 for moving a carriage 4 for placing a printing head 1 and second moving means 5 for moving a platen 6 along the moving direction of the head 1. When the print starting end position of next printing line data determined by determining means 12 is disposed at the side of the extension of the moving direction of the head 1 at the time of printing the preceding printing line data from the printing end of next printing line data, control means 13 so controls as to feed the platen 6 at a distance corresponding to one line by the means 5 after moving it to the vicinity of the position of the printing start end of the next printing line data without stopping the carriage 4 by the means 3 even after the printing of the preceding line data is finished. Accordingly, since the stopping position of the head relative to the preceding printing line data is set at a stage of storing the printing data for two lines in receiving buffer means, a pretreating time can be shortened.

Title: Recording or reproducing device
Inventor: KAWANO KENJI
IPC: G11B17/34
Filed: 1988-10-31
Abstract: PURPOSE:To always secure the stable and high reliability and also optimum head touch by keeping relationship between a stabilizing member and a recording medium in a positional relationship where positive pressure can always be generated. CONSTITUTION:When a stabilizing plate 5 is approached/separated to/from a magnetic disk 101, the stabilizing plate 5 is approached/separated to/from the disk surface, being turned by a stabilizing plate supporting member 2, while a revolving fulcrum (shaft 4) of the stabilizing plate supporting member 2 as to be a fulcrum for the turn is set up on the side of downstream in the rotating direction of the disk. Thus, the stabilizing plate 5 is always positioned to have a smaller gap with the disk surface of the downstream side than the upstream side, so that it is approached and separated keeping the positional relationship generating what is called positive pressure. Consequently, no negative pressure is generated in the course of the relative movement of the stabilizing plate 5 and the disk. By this method, the recording medium can be prevented from being damaged.

Filed: 1984-12-26
Abstract: PURPOSE:To accelerate correction of vehicle present location data positively and to improve accuracy of running guide information by displaying the state that an accumulated error of the vehicle present location from the actual location by arithmetic with the running increases on a display device. CONSTITUTION:The vehicle running direction and the vehicle running distance are detected by a direction sensor 7 and a distance sensor 10 respectively and the present location, a running locus, etc. of the vehicle are calculated by a control part 16 and a spot or the like close by the vehicle present location among the spots or the like stored in place name and spot data ROM1 is retrieved to display each mark of the present location P and the running locus T of the vehicle on a display screen 12a. Since the mark of the vehicle present location P displayed on the screen 12a is enlarged with the increasing of the running distance, the magnitude of the accumulated error taking place between the present location data calculated with the control part 16 with low detecting accuracy of the sensor 7 and the actual present location data can be easily recognized.

Abstract: PROBLEM TO BE SOLVED: To allow squeeze-molding for improved flatness while press- deformation is entirely is suppressed by hooking a reception punch to stripper packing plate, so that the reception punch and the stripper backing plate are interlocked for pressing down an upper surface side of a lead frame. SOLUTION: To prevent press-deformation of a lead frame 10 when a burr in a vis hole 3 of the lead frame 10 is squeeze-molded under press, an improved reception punch is hooked to a stripper backing plate 12. By this, an upper surface side of the lead frame 10 is pressed down by the improved reception punch 11 and a stripper 6 at the same time. So, the improved reception punch 11 is located at the same position with the stripper 6 at always. Thus, no space is generated on the side opposite to a squeeze molding die 5, or on upper part side, when the burr generated in the vis hole 3 of the lead frame 10 is squeeze- molded, from the beginning to the end, for high degree of flatness with no deformation.

Title: Vibration detector
Inventor: OKABE SHINICHI
IPC: G01M15/00
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To accurately detect a pressure vibration generated by pre-ignition distinguishing from another vibration by comparing the magnitudes of the detected vibration components of a plurality of frequency regions with a preset threshold value. SOLUTION: A vibration detecting sensor 5 detects the vibration along the frequency regions of, e.g. 1-10kHz, and transduces the vibration into electric signals. From these electric signal, the vibration components in the narrow bandwidths of, e.g. 8.0kHz and 4.5kHz are separated by BPFs 61 and 62. The electric signals passing through the BPFs 61 and 62 undergo amplifications 63 and 64 and A/D conversions 71 and 72, respectively, and the high-region side detected signal and the low-region side detected signal are inputted to an operating part 3. In the operating part 3, the magnitudes of these signal components are compared with a threshold value set by a vibration-component comparing means beforehand.  When there are a plurality of the vibration components, which are generated at the magnitudes larger than the threshold level, including the vibration components other than the frequency region of the vibration components that are intrinsic to knocking, it is judged that a pre-ignition is generated in a combustion chamber.
