Title: Video endoscope device
Inventor: KIMURA KENJI
IPC: H04N5/353
Filed: 1987-06-18
Abstract: PURPOSE:To obtain the clear image of a moving image to be filmed by controlling charge storage time by a solid image pickup element according to the output level of the soloid image pickup element. CONSTITUTION:Remarkable sensitivity deterioration is prevented by shortening the storage time and making a shutter speed quick when the output level of the CCD 33 is high. Then when the output level of the CCD 33 falls, it is prevented by extending the charge storage time and making the shutter speed slow. When the shutter function is turned on, a video signal is generated only at even number field and it is not generated at odd number field. As a video cannot be monitored by a monitor and so on as it is, the video signal generated at the even number fields is temporarily stored in the video memory of a video processor 36 and the video signal stored in the even number field is read and displayed on the monitor in the even number field. Thus the fixed sensitivity can be obtained by varying the shutter speed.

Abstract: PROBLEM TO BE SOLVED: To obtain a high precision, to lower the cost, and to save the space by detecting the position of a magnetic recording medium and controlling the speed of an electric motor according to information from the sensor. SOLUTION: A magnetic recording medium ticket 60 is carried by conveyor rollers 21 and 22 at a speed faster than a prescribed speed. And, when the front end of the magnetic recording medium ticket 60 passes by a sensor 40, the sensor 40 detects and reports that to a control part 70. The control part 70 once receiving the report on the passage of the front end of the magnetic recording medium ticket 60 indicates the output of null-bit information to a magnetic head 10. Further, the control part 70 varies the rotating speed of the electric motor 30 to a speed corresponding to the prescribed speed when the magnetic recording medium ticket 60 moves in between the magnetic head 10 and a conveyor roller 20 according to the time from when the ticket 60 has passed by the sensor 40 until when the ticket moves in between the magnetic head and conveyor roller 20. Consequently, the conveyance speed after the tickets moves in is set to the prescribed speed and the magnetic recording medium ticket 60 is carried stably at the prescribed speed during data writing.

IPC: G11B15/675
Filed: 1984-07-23
Abstract: PURPOSE:To prevent a record, etc., from being broken when it is caught at a front loading part by inverting the loading direction when detecting an overcurrent flowing through a motor driving circuit for longer than a specific time, and stopping the loading when the number of times of the inversion exceeds a specific value. CONSTITUTION:If an overload is placed on the motor 1 while a front part is open or closed, the overcurrent flowing through the motor driving circuit 2 is detected by an overcurrent detecting circuit 7, which sends a detection signal to a logical circuit 8. When this detection signal is inputted to the logical circuit 8 continuously for longer than the specific time, the logical circuit 8 inverts the loading direction and when the number of times of this inversion exceeds the specific value, the loading motor 1 is stopped. Consequently, a front loading mechanism and a motor driving circuit are prevented from being broken and if a record, etc., are caught at the front part, they are prevented from being broken.

Title: Method for coating straight line pattern for construction panel
Inventor: YAMAGUCHI TAKAHIRO
IPC: B05D1/02
Filed: 1994-06-09
Abstract: PURPOSE:To draw a straight line pattern with a straight contour without leaving an uncoated part. CONSTITUTION:Five fine pipe nozzles 11, for example, are arranged to a straight line pattern A and the fine pipe nozzles 11 for drawing contours of both sides of the straight line pattern A are shifted more backward in the carrying direction than the fine pipe nozzles 11 positioned on their insides to arrange the five fine pipe nozzles 11 in a V-shape as shown in (a).

Title: Tracking controller
Inventor: SEKIGUCHI TORU
IPC: G11B15/467
Filed: 1985-07-11
Abstract: PURPOSE:To keep a reproduction signal at its maximum level by using a tracking control means which detects the change of signal level of a reproduction head under control and produces a tracking control signal in response to the state of said level change. CONSTITUTION:When an image head is set at a position (a), the reproduction signals S are decreased on a track #1 with displacement of the image head in the direction (c) and then increased with displacement of the head in the direction (b) respectively. While on a track #2 the signals S are decreased and increased with displacement of the image head in the directions (b) and (c) respectively. When the results of tracks #N and #(N+1) are inverted with each other, it is decided that the image head is set at the center point (a) of a image track. Thus the control signal e2 is not replaced at the restart point of a track #3. As a result, the signal e2 is kept at the fixed value when the image head is kept on a track and the signal S is kept at the maximum level with a stable fixed amplitude.
