Title: Floppy disk device system
Inventor: OZAKI HISAMI
IPC: G11B19/00
Filed: 1983-02-28
Abstract: PURPOSE:To prolong the lifetime of a floppy disk and to prevent the useless consumption of an electric power source by performing the individual control of operation of a driving spindle motor to plural floppy disk devices. CONSTITUTION:Signal cables 21a-21d transmit the driving control signals of a spindle motor delivered from a controller 20 to floppy disk devices 10a-10d respectively. The controller 20 delivers OFF signals to the floppy disk devices 10b-10d through signal cables 21b-21d. Thus the devices 10b-10d stop the reading/writing actions of data until each selection signal is delivered from the controller 20. In such a way, the revolution can be assuredly discontinued for the spindle motor of the floppy disk device which needs no operation. As a result, the overall lifetime can be prolonged for a floppy disk device.

Title: Method for forming fine regist pattern
Inventor: KUBOZONO KENICHI
IPC: G02F1/1368
Filed: 1991-02-01
Abstract: PURPOSE:To form a fine and adequately thick pattern accurately, clearly, efficiently and inexpensively by a method wherein, after an ink filled in the incised design parts of an intaglio has been hardened, another ink is refilled therein and the image carried therein is transferred on the material to be printed by the adhesive strength of the second ink. CONSTITUTION:After the ink 3 filled in the incised design parts 2 of an intaglio 1 has been hardened, an ink 6 is refilled therein and the image carried therein is transferred on a base plate. Therefore, the hardened ink 3 in the incised design parts 2 is adhesively impressed with its figure retained as such on the base plate by the adhesive strength of the unhardened ink 6. Moreover, even if the first ink 3 is shrunk and reduced in volume during its hardening process, the reduced volume is made up for by the second ink 6 and, therefore, the inks 3 and 6 are firmly attached to the base plate to make a smooth image transfer possible. Accordingly, a fine regist pattern consisting of such inks 3 and 6 is formed matching exactly with the design on the plate. Since the ink 3 received in the incised design parts 2 of the intaglio is not squashed upon image transfer, the pattern having an adequate thickness can be formed.

Title: Electrophotographic copying machine
Inventor: YOSHIKAWA SHINICHI
IPC: G03G21/00
Filed: 1982-03-01
Abstract: PURPOSE:To improve efficiency of copying operation, by storing operation state when a start switch is operated before a fixation device does not reach a temp. capable of fixation after closing a power supply switch is conducted, and starting copying action automatically at the moment the fixation device reaches the fixing temp. CONSTITUTION:A temp. sensor is arranged in contact with a heating roll 16. When a start switch is operated after a power supply switch is conducted, if the temp. of the roll 16 detected reaches a fixation temp., a start lamp is lightened to inform an operator of start of copying action and instantaneously to start actual action. If the roll 16 is not yet reached the fixation temp., logical decision is returned, and such judgement is repeated. Therefore, the operation state of the start switch is stored. While such judgement is repeated, the roll 16 reaches the fixation temp., at that time, the start lamp is lightened and copying action is commenced. Accordingly, the operator need not wait near the copying machine until the temp. reaches the fixation temp.
