Title: Power source for welding
Inventor: TODA TAKETOSHI
IPC: B23K9/073
Filed: 1983-09-16
Abstract: PURPOSE:To provide a titled power source which reduces the size of a semiconductor inverter circuit of a power source for welding and operates effectively and uniformly said circuit by using a capacitor transformer output method for said inverter circuit and prohibiting semiconductor elements from restarting until the capacitor discharges thoroughly. CONSTITUTION:An AC power source 1 is rectified by a rectifier circuit 2 to DC which enters an inverter circuit 3. The current of which the frequency is increased by semiconductor switching elements 31-34 is converted to prescribed AC by a transformer 36 for taking out output. The AC is again rectified to DC by a rectifier circuit 4 and the DC is fed via a DC reactor 5 to an output terminal 6. When an inverter start-stop circuit 7 is turned on, an inverter control circuit is actuated by a time limiting circuit 9 to prohibit operation of the elements 31-34 for specified time. The discharge circuit 12 of a capacitor 35 is switched S on so that the capacitor discharges thoroughly during this time. The failure of the elements 31-34 is prevented by the through discharge of the capacitor 35. The iron core for the transformer 36 is thus minimized and the circuit 3 is effectively and uniformly actuated.

The height of the guide posts 10 and 12 is set so that the post 10 can control the lower part of a tape and the other post 12 can control the upper part of the tape. By giving such a small angle to the guide post for controlling tape at the time of reverse running in the direction of length of the tape, the tape control force is intensified and stable tape running can be obtained even when a tape is run in the reverse direction.

Title: Information recording device
Inventor: SETO KAORU
IPC: G06K15/00
Filed: 1992-06-30
Abstract: PURPOSE:To enable the profile of a character or a figure to be printed smoothly and at the same time, a color intermediate tone image to be highly improved quality-wise. CONSTITUTION:A controller 102 converts R, G, B color images to Y, M, C, K signal in accordance with a command issued by a host computer and output the signal to a dither smoothing circuit 104. The dither smoothing circuit 104 detects whether entered image information matches one of previously determined information groups. If the circuit 104 detects that the information matches one of the previously determined information groups, the circuit 104 converts the cord information of a specified highlighted pixel. After that, the circuit 104 sends the converted information to a printer engine 103, modulates a light beam based on a conversion signal, and scans the light beam to the surface of a photosensitive drum to record data. This conversion allows an intermediate tone image to be recorded by extracting a color dither image part for each color and improving the quality of the image highly, and further, modulating the image part to a pixel signal for a lower density than a scan line density.
