Patent JP-H0846204-A (JP)
Title: Display device
Inventor: ONO EIZO
IPC: G02F1/1368
Filed: 1994-07-28
Abstract: PURPOSE:To bring field concentration generated in the drain-side P-N junction section of a transistor immediately after the completion of charging to zero, reduce the leakage current and prevent the deterioration of an image signal by connecting a thin-film transistor in series and mounting a capacitor on the connecting section of the thin-film transistor. CONSTITUTION:A capacitor 20 is connected previously to the connecting section 21 of transistors 18 and 19. When gate voltage 18V is applied to a wiring 17, voltage is applied to the gate electrodes of the transistors 18, 19, the transistors are brought to an on state, and an image signal is charged to capacitors 20 and 15 with a delay of 20 milliseconds. Gate voltage in pulse width of 200 milliseconds is changed into -15V, the transistors 18 and 19 are brought to an off state, and the image signal is also altered to 0V with a delay of 20 milliseconds. Voltage between the source and drain of the transistor 18 is 0V because the voltage of the capacitors 15 and 20 is equalized approximately. Accordingly, there is no field concentration in the drain-side P-N junction section of the transistor 18, thus extremely reducing leakage currents.

IPC: G11B5/85
Filed: 1987-07-16
Abstract: PURPOSE:To obtain a magnetic recording medium which provides excellent S/N in high-density recording and has good still durability under high humidity by introducing gaseous oxygen contg. a slight amt. of ammonia into the vapor deposition vessel at the time of subjecting a ferromagnetic alloy to oblique vapor deposition. CONSTITUTION:The gaseous oxygen contg. the slight amt. of the ammonia is introduced into the vapor deposition vessel at the time of depositing the ferromagnetic alloy obliquely by electron beam evaporation onto a high-polymer film is moving along a rotary base 2.

Title: Integrated circuit for read-write amplifier
Inventor: SOHARA YASUYUKI
IPC: G11B20/10
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To provide an IC capable of correctly operating an AGC amplifier(an automatic gain control amplifier) in a subsequent stage after the lapse of shorter and more appropriate period of time from an R/W(write/read) switching time. SOLUTION: An R/W signal is applied to a masking signal generator 5. The masking signal generator 5 provides a masking signal having a time width which is determined by a resistor R1 and a capacitor C1 included therein for setting a time constant. The masking signal is applied to a latter-stage amplifier 3b in a read amplifier 3 to thereby restrain an amplifying operation of the amplifier 3b. On the other hand, the masking signal is also applied to a one-shot circuit 11 so as to generate, upon the termination of the mask signal, an input- restriction signal having a time width T0 which is determined by a resistor R2 and a capacitor C2 included therein for setting a time constant. The input- restriction signal is applied to an input-shortcircuit switch 10 of the AGC amplifier 8.  Thus, an input to the AGC amplifier 8 is further restricted for a time period of T0 from the time when the restriction on operation of the read amplifier 3 was released, thereby, the amplifying operation of the AGC amplifier 8 is allowed to start at the time when a stable output, signal is provided from the read amplifier 3.

Title: Cementing method for adherend
Inventor: HIBINO SATORU
IPC: B29L17/00
Filed: 1991-06-24
Abstract: PURPOSE:To simplify and make automatic respective processes of cementing adherends by cementing the adherends in two stages consisting of temporary fixing by means of an adhesive layer and proper fixing by means of heat curing of the adhesive layer. CONSTITUTION:A curable resin composition containing an active energy ray curable resin component and a thermosetting resin component is applied to one or both of adhesive faces of adherends to be cemented each other. Active energy rays such as ultraviolet rays or electron radiations are emitted to a coated layer to form an adhesive layer. Then adherends are stuck together through the adhesive layer, and the adhesive layer is heated and cured to fix the adherends each other. As the adhesive layer is formed simply by emitting the active energy rays such as ultraviolet rays or electron radiations to the coated layer of the curable resin composition, the adherends to be cemented each other can be temporarily fixed instantly and further the adherends can be fixed firmly each other by heating and curing the adhesive layer. The improvement of productivity, shortening of line tact and cost reduction can be realized by said arrangement.
