IPC: H01L29/786
Filed: 1983-12-22
Abstract: PURPOSE:To prepare an MOSFET capable of operating at high speed by forming the MOSFET consisting of a polycrystalline InP semiconductor film on a glass or quartz substrate. CONSTITUTION:A Cr gate electrode 2 and an Si3N4 film 3 are formed on the surface of a glass substrate 1, and an InP film 4 is shaped on the film 3 under an amorphous state. The film 4 is brought to a polycrystalline state through laser annealing, etc., and formed to a partially insular shape through photoetching. An Si3N4 film 5 is formed, and contact holes for leading out electrodes from sections as source-drain regions are shaped. Electrode wirings 6, 7 by Si are formed. The film 4 can also be used as a resistor on an IC. Accordingly, an MOSFET having high carrier mobility can be formed, and particularly a driving circuit for an active-panel for a TV display board can be unified.

Title: Orifice plate and production thereof
Inventor: KISHIMOTO MITSURU
IPC: B41J2/135
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To shorten the machining time while enhancing the machining accuracy. SOLUTION: The orifice plate comprises a preliminary shaped hole 25 made in the surface S2 on the ink pressurizing chamber 24 side and an orifice formed by laser machining to conduct the ink pressurizing chamber 24 side with the ink drop ejecting side at the part of the preliminary shaped hole 25. Since the part of the preliminary shaped hole 25 is subjected to laser machining and an orifice is formed by conducting the ink pressurizing chamber 24 side with the ink drop ejecting side, no mask is required. Since alignment of mask and an original die 21 is not required, machining accuracy of an orifice plate can be enhanced. Since the machining thickness is decreased by an amount corresponding to the preliminary shaped hole 25, number of machining shots can be decreased resulting in shortening of machining time.

Title: Light refracting device
Inventor: SHINGU MASATAKA
IPC: G02F1/29
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To refract the incident light at a desired angle and to arbitrarily control the focus position by changing the electron state of a substance having conjugate electrons to change the refractive index of the substance and scanning the light emitting from a first light-transmitting device or second light- transmitting device. SOLUTION: Since the entrance face and exit face of a first light transmitting device 31 are tilted in the yz-plane, the exiting light from the first light- transmitting device 31 is refracted and diffused in the z direction. Since the entrance face and exit face of a second light-transmitting device 32 are tilted in the xy-plane, the exiting light from the second light-transmitting device 32 is refracted and diffused in the x direction. By arranging the light-transmitting devices 31, 32 with the entrance faces and exit faces for light tilted in one of the xy plane, yz plane and xy plane, the exiting light from each light- transmitting device can be refracted and diffused in a desired direction. Further, by controlling the intensity and direction of the electric field applied, the light can be arbitrarily scanned.

Title: Bidirectional amplifier circuit
Inventor: MATSUDA MITSUHIRO
IPC: H03F3/62
Filed: 1987-09-30
Abstract: PURPOSE:To prevent an echo, etc., and to simplify circuit constitution by respectively composing the gain control circuit of a high gain side amplifier of one transistor and the gain control circuit of a low gain side amplifier of a transistor to be Darlington-connected. CONSTITUTION:When the characteristics of transistors TR1 and TR2 and a control signal is inputted to a terminal IN, an impedance between the collector and emitter of the TR1 and TR2 is equally changed (reduced). In a low gain side amplifier A2, the TR2 and TR3 are Darlington-connected and since the TR2 further controls the base of the TR3, the impedance between the collector and emitter of the TR3 goes to be 1/hfe (the hfe is a small signal current amplification factor) of the impedance of the TR1 and TR2 in an active area. Thus, the lowering of the gain of the amplifier A2 proceeds and the gain of an amplifier A1 goes to be high with following this. Accordingly, the total gain of the amplifiers A1 and A2 at a transient time goes to be lower than a normal time and the echo, etc., is prevented from being generated.

Abstract: PURPOSE:To provide thermal bonding property and higher bonding strength at a high temperature and at the same time excellent property of a sheet itself by integrally combining uncrosslinked rubber layers of ethylene-alpha olefin rubber having different crosslinking rates to form a crosslinked layer and a semi- crosslinked layer by thermal crosslinking treatment. CONSTITUTION:An ethylene-alpha olefin uncrosslinked rubber layer (layer A) having high crosslinking rate and an ethylene-a olefin uncrosslinked layer (layer B) having low crosslinking rate are formed separately by means of extruders so as to be integrally combined with each other or are integrally formed simultaneously by means of two-layer extruders. Adjustment of crosslinking rates is effected mainly by the selection of ethylene-alpha olefin rubber itself and by the selection of crosslinking agents, accelerators and auxiliary agents. As crosslinking agents to be used, sulfur, peroxide, quinoid etc., are used, wherein sulfur is most preferable, In order to adjust the crosslinking rates of phase A and phase B in the case of sulfur, the kinds and amounts of the accelerators are utilized. Heating and crosslinking treatments are carried out by setting heating temperature and time in such a manner that the layer A becomes a crosslinked layer 1 and the layer'' becomes a semi-crosslinked layer 2.
