Title: Power feeder for video camera and video light
Inventor: TAKAGI FUMIAKI
IPC: H04N5/225
Filed: 1993-04-02
Abstract: PURPOSE:To make the efficient use of a battery by devising the power feeder such that no current flows when the video camera is not mounted, a feeding current to the camera is set small in the photographing preparation process to let a light emission section emit no light and the supply current is increased to light the light emitting section when the photograph is started. CONSTITUTION:A voltage detection resistor 18 provided to a battery set 12 detects the quantity of a feeding current to a video camera 11 as a voltage and the difference between a detection signal S1 and a reference signal S2 is amplified by an error amplifier 19. Then an output signal S3 from the amplifier 19 is compared with a reference signal S4 at a comparator 20 and when the signal S3 is larger than the signal S4, a low level output signal S5 is generated. Then the signal S5 turns on a switching transistor(TR) 21 and then turns on a switching TR 22 to light up a light source lamp 23. Through the constitution above, the reference signal S2 is changed within a prescribed range in the operation process and when the camera 11 is set to the image pickup mode, the signal S2 activates the switching circuit and when the camera 11 is set to the preparation mode, the circuit is inactivated.

Title: Method and equipment for inspecting welded part of steel band
Inventor: OTANI KAZUHIRO
IPC: G01N3/00
Filed: 1993-04-26
Abstract: PURPOSE:To decide the pass/fail of welding quickly without relying on the feeling of expert by running a press roller on a weld line immediately after welding while pressing the roller downward and then deciding the pass/fail of welding based on the crack at the welded part. CONSTITUTION:After positioning the rear end of a preceding steel band and the front end of a following steel band, welding disc electrodes 6, 6' are shifted while rotating from one end toward the other end in the breadthwise direction of the band steel along a weld line thus welding the preceding and following steel bands. A press roll 10 is shifted while rotating from the rear of the electrodes 6, 6' while spacing apart therefrom by a predetermined distance thus pressing the weld line immediately after welding. The press roller 10 is coupled with a press cylinder 11 which is coupled with a hydraulic pressure source through a hydraulic solenoid valve 12. Since the required pressure varies depending on the thickness or material of the steel band, a pressure conversion valve 13 and a pressure gauge 14 are provided for the hydraulic circuit. When a crack due to press is detected visually or by means of a camera or photoelectric device, the steel bands can be welded immediately under clamped state thus minimizing the line stop time.

Title: Image forming device
Inventor: INUKAI KOREMASA
IPC: G03G15/08
Filed: 1983-06-06
Abstract: PURPOSE:To guide accurately an image forming process unit while keeping a specific interval to a photosensitive body even when foreign matter such as toner sticks to the surface of the photosensitive body and becomes firm, by forming a groove in the surface of a guide roller on which the photosensitive body abuts, and reducing the abutting area, and forming a space between the guide roller and photosensitive body. CONSTITUTION:The outer circumferential surface of the guide roller 1 where endless grooves 1a are formed in parallel to one another abuts on image nonformation areas (both end parts) of the photosensitive body 2, and the gap G is formed between a developing roller 3 and the photosensitive body 2. If toner scatters to stick the image nonformation areas and becomes firm, the guide roller 1 passes over the foreign matter in rotating, but the foreign matter escapes into the space formed between the photosensitive body 2 and grooves 1a and the guide roller never presses tha entire surface of the foreign matter. Therefore, the guide roller 1 rotates abutting on the photosensitive body 2 without exerting any influence upon the foregin matter, and the developing roller 3 is guided invariably at an accurate specific interval G to the photosensitive body 2.
