Title: Gaas fet
Inventor: SAITOU AKIRA
IPC: H01L29/872
Filed: 1984-01-09
Abstract: PURPOSE:To improve the high frequency characteristic as a whole by a method wherein the drain side eaves of a gate electrode are formed longer than the source side ones. CONSTITUTION:A nitride film 3 is formed as an insulation film on the active layer 2 of a GaAs high-resistant substrate 1, and an aperture for gate electrode formation is provided. Then, a metal film 4 forming a Schottky contact with the active layer 2 is evaporated. A photo resist film 5 convering the gate region with a smaller width (a) on the source side and a larger width (b) on the drain side is formed. A gate electrode 4' and a patterned nitride film 3' are formed by etching. N<+> layers 6 and 7, high concentration carrier layers of an ohmic contact region, are formed by ion implantation, and then a source electrode 8 and a drain electrode 9 are formed. The distance between the gate and the source is short, and that between the gate and the drain is long; thus, the reduction in source resistance and the increase in mutual conduction can be made, and the increase in frequency can be attained.

Title: Receiver
Inventor: INAO KIYOHARU
IPC: H04J1/00
Filed: 1992-01-08
Abstract: PURPOSE:To separate a high frequency signal component from a low frequency component by comparing output signals of a decimation low pass filter and an A/D converter and outputting the resulting signal as the high frequency component. CONSTITUTION:A decimation low pass filter LPF 13 receives a digital code signal N times and outputs a low frequency signal of the digital signals received N times. Moreover, an A/D converter 11 samples an instantaneous value of a hybrid communication-signal and converts it into the digital code signal. Then an output signal Davg of the LPF 13 and a digital code signal Dj outputted from the converter 11 are inputted to a comparator 15, in which two digital signals are compared, Then the high frequency component of the resulting signal is outputted from the comparator 15. Since the circuit scale and the arithmetic operation capability are small, the introduced hybrid communication signal is separated into a low frequency component and a high frequency component by having only to use one LPF 13.

Title: Electrifying device and image forming device provided therewith
Inventor: OTSUKA KEIZO
IPC: G03G15/02
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent the resistance of an electrifying roller from rising with the increase of the number of image forming times and to prolong the life of the electrifying roller in an electrifying device uniformly electrifying the surface of a photoreceptor drum by applying DC voltage on the electrifying roller coming in contact with the surface of the photoreceptor drum. SOLUTION: The electrifying roller 2 is constituted of a core bar 2c, an elastic layer 2a on the periphery of the core bar 2c, and a resistance layer 2a2 on the periphery of the layer 2a, and arranged in contact with the surface of the photoreceptor drum 1. A leveling roller (leveling member) 11 is arranged in contact with the roller 2 and is connected to a power source 3. By applying the DC voltage on the core bar 2c from the power source 3, the surface of the drum 1 is electrified to specified potential. At such a time, the DC voltage whose absolute value is larger than that of the DC voltage applied on the core bar 2c is applied on the member 11 by the power source 3 simultaneously, so that a current flows in the roller 2 from the member 11.  Thus, the offset of the conductive ion of the resistance layer 2a2 in the roller 2 is eliminated so as to prevent the resistance value from rising.

Title: Dope composition for release layer
Inventor: YAMAZAKI KAZUHIRO
IPC: C08L1/00
Filed: 1987-01-09
Abstract: PURPOSE:To improve the adhesion and soft flexibility of a release layer at the time of storage and the plastic cutting and releasability of the same layer at the time of hotstamping by formulating a specific resin composition of cellulose acetate and a plasticizer, a low boiling- point organic solvent and intermediate, high boiling-point organic solvents at a specific ratio. CONSTITUTION:A comparatively large amount of low-boiling point organic solvent and a comparatively small amount of intermediate, high boiling-point organic solvents are formulated with a resin composition of 5-30 weight parts of plasticizer based on 100 weight parts of cellulose diacetate having a degree of substitution of 2.2-2.6 to obtain a dope for formation of a release layer. The low boiling-point solvent includes a solvent whose boiling point is below the temperature level of 70 deg.C or lower, and acetone, acetone/methanol, etc., are used. On the other hand, the intermediate/high boiling-point solvents represent solvents whose boiling point is above the temperature level of 70 deg.C or higher, and methylethylketone, cellosolve, etc., are used. If the low boiling-point solvent is used as a main solvent (65-80 weight parts based on the weight of dope), and then the intermediate/high boiling-point solvents are formulated to the former at a ratio of 5-30 weight % based on the weight of dope, then brushing does not occur easily on a running film. If the concentration of the resin composition in the dope is set to 5-15 weight %, the viscosity decreases advantageously.
