IPC: G03G21/00
Filed: 1995-06-28
Abstract: PURPOSE: To prevent a careless mistake, that is, one-side copying caused by forgetting to specify both-side copying by actuating a reverse lever, so as to feed an original to a carrying belt for rear copying, when a both-side copying button is depressed. CONSTITUTION: An optical scanner 4 scans the rear of the original and detects the fact that a character and a pattern exist or not, to inform a first control part 8. In a copying part 6, the front side of the original is copied at a position 13 and then, the first control part, 8 stops the ejecting of the original and lights a rear-side lamp for warning that the rear side is copied or not in a display part 9, when the rear is expected to copy and the one-side copying is specified, from the results of the detection.  When the both-side copying button 12 is depressed, a second control part, 10 lays the lever 7 fallen to a both-side copying side and carries the original at the position 13 to a position 15 and then, to a position 16 by a paper carrying roller 3, so that the original is turned over by the paper carrying roller 3 and returned to the copying part 6 at the position 13, to copy the rear.

Title: Preparation of hollow synthetic resin molding
Inventor: YAMAZAKI TEI
IPC: B29L22/00
Filed: 1985-07-25
Abstract: PURPOSE:To make it possible to form a molding of a complicated shape in high accuracy and with less irregularity of the thickness, by adhering a small amount of synthetic resin, which is placed in the space of a mold being kept under vacuum condition, on the surface of the mold by rotating the mold during the curing period, while the closely sealed vessel is also kept under vacuum condition during the molding period. CONSTITUTION:The inside of a closely sealed vessel 1 and the space for molding 6 in a mold 2 are kept under reduced pressure of a specified vacuum condition. A synthetic resin liquid A of volume smaller than the volume of the mold space 6 is poured in the mold space 6 and the mold 2 is then rotated by means of a motor. The rotation of the mold 2 continues until the curing of the resin is completed. As the curing uniformly goes on and the resin liquid adheres over the whole surface, the thickness of the resin becomes uniform over the direction of the circumference. The synthetic resin liquid A therefore reaches all the corners even if the surface of the mold 5 has a complicated shape and it is made possible to mold in high accuracy.

Title: Erasion system for magnetic recording
Inventor: SOGA TAKASHI
IPC: G11B5/024
Filed: 1986-07-14
Abstract: PURPOSE:To attain a satisfactory erasion system for magnetic recording by using an erasion signal within a frequency band of a video signal to erase the signal written to a magnetic recording medium and then using an erasion signal out of the frequency band of the video signal to erase the erasion signal written previously to the magnetic recording medium. CONSTITUTION:The gradually decreasing erasion signals S6 and S7 which are amplified via a recording amplifier 3 are written to a track 5a of a floppy disk 5 by a magnetic head 4. In this case, the amplifier 3 is actuated by a recording signal S8 of a control circuit 7. The signal S6 of 6MHz is written to the track 5a where a signal is already written via the head 4. Thus the signals within the frequency band of a video signal are erased. In this case, the frequency component of the signal S6 remains on the track 5a at a comparatively high level. Then the signal S6 of 14MHz is superposed on the track 5a via the head 4. Thus the signal S6 is completely erased.
