Title: Video recording system
Inventor: SHINPO NAOYUKI
IPC: H04N7/18
Filed: 1990-10-22
Abstract: PURPOSE:To surely record the image from a sensor operation time point by providing a video delay fircuit for delaying a video signal by a VTR actuation time portion until the system becomes a state that picture recording can be executed completely, on a pre-stage of a VTR, and setting a video delay time. CONSTITUTION:A video delay memory device 2 sets a VTR actuation time (tr) until a VTR 3 is actuated from a stop state by a picture recording control signal 7a and can execute picture recording completely, for instance, to three seconds. In such a state, a video signal from a television camera 1. is inputted to the video delay memory device 2, delayed by three seconds and sent out to the VTR 3. Accordingly, when a sensor 6 detects abnormality of a body to be photographed and sends out a picture recording control signal 7a to the VTR 3 through a VTR controller 7, the VTR 5 requires an actuation time of three seconds and starts picture recording. At that time point, the video signal supplied to the VTR 3 becomes a video signal of an operation start time point of the sensor 6, therefore, an image from an abnormality generation time point can be recorded surely.

Title: Gear
Inventor: TAKAHASHI TOSHIO
IPC: F16H55/17
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To correspond to secular change and change of environment in use and reduce noise effectively owing to comparatively simple configuration by providing an elastic buffer member between an inner peripheral face of a gear wheel and an outer peripheral face of a gear core and connecting the gear wheel and the gear core only by the elastic buffer member. SOLUTION: Since a gear wheel 12 is held in a gear core 15 through an elastic buffer member 20 in a floating condition in a gear 10, vibration due to mesh of a tooth 11 is absorbed by the elastic buffer member 20 and is not transmitted to the gear core 15 side. Moreover, even if the tooth oscillates, the elastic buffer member 20 is expanded, shrunk, and deformed, and the tooth 11 follows a mating gear to absorb oscillation. Consequently, noise due to mesh of the tooth 11 is reduced greatly, and the reduction of noise is achieved by a comparatively simple configuration without necessitating high dimensional accuracy in each section. Moreover, even if the tooth 11 is worn and each section is expanded, they are absorbed by the elastic buffer member 20, and it is possible to correspond to secular change and change of environment in use.

Title: Semiconductor device and manufacture thereof
Inventor: SHINOHARA SHOHEI
IPC: H01L29/78
Filed: 1989-10-30
Abstract: PURPOSE:To prevent hot carrier deterioration and increase mutual conductance, by making a second source/drain diffusion layer and gate electrode face each other via a gate oxide film, which diffusion layer is selectively formed by applying shadow effect. CONSTITUTION:Ions are selectively implanted in the sidewall of a recessed part 6. The selectivity for the sidewall part is obtained by setting the ion implantation angle to be equal to theta or larger, and applying the fact that ions are not implanted in the bottom of the recessed part 6 as the result of shadow effect of ion implantation. The above oblique ion implantation is performed from right and left, and then heat treatment is performed, thereby forming an N<-> diffusion layer 7. After that, the inner wall of the recessed part 6 is oxidized and a gate oxide film 8 is formed; N<+>-doped polycrystalline silicon, e.g. is deposited; by using a pattern larger than the periphery of the recessed part 6, the polycrystalline silicon is etched to form a gate electrode 9. Hence the bottom surface of the recessed part 6 corresponds to the channel part of a transistor, and the outer side and the sidewall of the recessed part 6 correspond to the source/drain region. Thereby excellent effect for hot carrier deterioration and mutual conductance can be obtained.
