Title: Semiconductor memory device
Inventor: NAKAHARA MASAKIMI
IPC: H01L29/792
Filed: 1988-04-28
Abstract: PURPOSE:To eliminate deviation of operating characteristics of each memory cell by setting the dielectric of electrostatic capacity of erasure circuit of EEPROM to the same layer as the gate insulation film of a floating gate PET constituting ROM. CONSTITUTION:A dielectric of electrostatic capacity C of erasure circuit is formed at the same process as the same layer as a FET gate insulation film GI of each memory cell with a floating gate FG of EEPROM and a thin tunnel window T at the gate FG and capacity C is made to be the same thickness. Thus, even if the strength of electric field applied to the tunnel window T of FET becomes higher, the time constant CR of circuit becomes larger, and actual writing and erasure time become shorter and the shift amount of threshold voltage automatically becomes constant. As a result, deviation of characteristics of each memory cell can be solved.

IPC: G03G9/113
Filed: 1987-04-27
Abstract: PURPOSE:To improve the electrostatic chargeability, wear resistance, water repellency and electrostatic charge stability of a carrier by coating the surface of the carrier with a hydrocarbon-based plasma-polymerized film contg. fluorine and a metal. CONSTITUTION:The surface of a carrier is coated with a hydrocarbon-based plasma-polymerized film contg. fluorine and a metal. For example, parallel flat electrodes 12 are arranged in a bell jar 11, a plastic vessel 14 contg. carrier powder 13 is put on the lower electrode 12 and brought into contact with a vibrating bar 15 and vibration is applied to the entire vessel 14 with a vibrator 16. High frequency power is supplied to the electrodes 12 to generate plasma and a monomer introduced into the bell jar 11 is plasma-polymerized. Since the carrier powder 13 is always under convection, the surface can be uniformly coated with the plasma-polymerized film. Thus, the electrostatic chargeability, electric resistance, wear resistance and water repellency of the carrier can be improved.

Filed: 1988-04-28
Abstract: PURPOSE:To prevent the generation of bubbles and cracks by passing a gas at a specified flow rate at the time of heating and vitrifying the porous glass preform for optical fibers under reduced pressure while passing the gas. CONSTITUTION:An aggregate 3 of fine glass particles is set in a pressure vessel 1 provided with a gas inlet 2, heated by a heater 5, and vitrified under reduced pressure in an inert gas or halogenous gas atmosphere.

Title: Control voltage generating circuit of luminance adjustment
Inventor: ISHIKAWA KATSUMI
IPC: H04N5/63
Filed: 1982-06-19
Abstract: PURPOSE:To prevent a fault picture from being displayed, by connecting a resistor in series with a diode which is turned on with a power supply switched off and a discharge current of a capacitor flows therethrough, for relinquishing almost instantly a picture with the power supply switched off. CONSTITUTION:When a main power supply +B1 is applied, a capacitor C1 is charged to slow down the leading of a control voltage for luminance adjustment. Further, when a power supply +B2 is changed from the transient state to the steady-state, the charging voltage of the capacitor C1 is equal to a voltage lower by about 0.4V than the control voltage for luminance adjustment, allowing to turn off diodes D1, D2. When the power supply +B1 is interrupted, the voltage of the power supply +B1 is decreased, the control voltage for luminance adjustment is decreased, and the charging voltage of the capacitor C1 is decreased, the diode D1 is turned on. Since the discharge current is limited with a resistor R9 although the capacitor C1 starts discharging, the positive feedback operation progressing the voltage decrease of the power supply +B2 is limited.
