Inventor: HIRAOKA SABURO
IPC: B41M5/50
Filed: 1984-07-20
Abstract: PURPOSE:To enhance dry transfer color-forming property using cation dye by applying cation dye-colorable acrylonitryl polymer containing a specific dose of alkyline carbonate on one side of a transparent film at a melting point of 150 deg.C or more. CONSTITUTION:A solvent solution consisting of resolved cation dye-colorable acrylonitryl polymer containing 20-50wt% of alkyline carbonate is prepared. Next, the solvent solution consisting of the afore-mentioned polymer resolved is coated on at least one side of a transparent film at a melting point of 150 deg.C or more. After this process, the coat is dried and the solvent is removed, thus obtaining a transparent film having dry transfer color-forming property using cation dye for color hard copy.

Title: Compound semiconductor static memory
Inventor: KADOYA YUTAKA
IPC: H01L27/10
Filed: 1987-06-17
Abstract: PURPOSE:To decrease erroneous operation in reading or writing data, by providing a switching MESFET of a depression type and applying an output from a Y decoder to the FET after shifting the level of the output. CONSTITUTION:An output from a Y decoder 5 is supplied to a gate of an MESFET 21 constituting a level shifting circuit 20. When a gate input to the FET 21 is 'high', the FET 21 is turned ON and a gate input to an MESFET 11 becomes 'high'. When a gate input to the FET 21 is 'low', the FFT 21 is turned OFF and an input to the FET becomes 'low'. Since a diode D serves as a level shifter, it is possible to keep the FET 11 completely ON when the gate level of the FET 11 is high, as well as to keep the FET 11 completely OFF under its pinch-off voltage when the gate level thereof is low, Consequently, signals on a data line can be amplified sufficiently by a sensing amplifier 2.

Title: Ink jet recorder
Inventor: OKAMOTO TORU
IPC: B41J2/06
Filed: 1988-06-21
Abstract: PURPOSE:To reduce energy for flying ink droplets and to decrease the capacity of a power source by composing the surface of the ink discharge end of an ink injection board to be coated with liquid repellent. CONSTITUTION:The ink discharge end E of an ink injection board 21 is coated with fluororesin to form the part to exhibit liquid repellency. Ink I from an ink supply plate 22 runs over styluslike electrodes 24, and the ink I is repelled at the part by means of its liquid repellency at the end E, while the surfaces of the electrodes 24 become easy to flow with metal. Accordingly, the end shape of the ink I spreading on the board 21 become uneven protruding at the electrodes 24. Thus, since it is held in raised shapes over the electrodes 24, it is easily released from the raised part thereby flying the ink I even with the application of relatively low energy thereto.
