Abstract: PURPOSE:To relax concentration of an electric field near a barrier which is generated when an inverse voltage is applied to the barrier and enhance high breakdown strength effect by specifying the thickness of a tunnel barrier layer, the height of a potential barrier, and a sheet resistance constituting a semiconductor device, respectively. CONSTITUTION:A high-resistance N-type region 3 is accumulated on an N<+> type region 2 consisting of GaAs when creating a Schottky barrier diode by the epitaxial growth method for forming a semiconductor substrate 1. Then, a Ta thin layer is vacuum- deposited on the entire surface of the region 3 and is heat-treated for forming a tunnel barrier film consisting of a Ta oxide film thin layer 4 which functions as an insulating material thin layer. At this time, the thickness is set to 10-200Angstrom , potential barrier between itself and a semiconductor region is set to 0.3eV or more, and this sheet resistance is prescribed to be 10kOMEGA/square or more. After that, the central part of element is eliminated by etching to enable an opening 5 to be provided, to enable it to be embedded by an Al barrier electrode 6 contacting the region 3 for creating a rectification barrier, and to cause a Schottky barrier 7 to be produce on the interface. Then, an ohmic electrode 8 and an electrode 12 are mounted on the rear surface of the substrate 1 and on the electrode 6, respectively.

Abstract: PROBLEM TO BE SOLVED: To prevent burning of a liquid crystal near an upper part of barrier ribs by forming an electrically conductive layer between a dielectric sheet and barrier ribs. SOLUTION: This device has a flat panel structure formed by laminating a liquid crystal cell 1, a plasma cell 2 and a dielectric sheet 3 between the cells. The liquid crystal cell 1 has a plurality of data electrodes and a liquid crystal layer 4 which fills the space between the dielectric sheet 3 and data electrodes. The plasma cell 2 has a glass substrate 5, plasma chambers 6, cathodes 7, anodes 8 and barrier ribs 9. The cathode electrodes 7 and anode electrodes 8 in a stripe pattern are formed on the glass substrate 5, and barrier ribs 9 in the stripe pattern are formed under the dielectric sheet 3. Electrically conductive layers 10 are formed between the dielectric sheet 3 and tops of the barrier ribs 9.  Since the conductive layers 10 have a part exposed to the inside of the plasma chambers 6, the potential in the plasma chambers 6 can be made equal to the potential of the conductive layers 10 on the barrier ribs.

Title: Hand-free circuit
Inventor: TAMATE YASUMASA
IPC: H04M1/60
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To avoid a sense of incongruity as if muting were caused even when attenuation is adjusted, for example, maximized or minimized in each attenuator. SOLUTION: A Tx attenuator 3 attenuates a voice signal of a talker by a preset amount and outputs the resulting signal to a receiver. An Rx attenuator 13 attenuates a voice signal of the receiver by a preset amount and outputs the resulting signal to the talker. A resistor R1 connects in parallel with the Tx attenuator 3 as a transmission leak circuit. A resistor R2 connects in parallel with the Rx attenuator 13 as a reception leak circuit. Since each leak circuit leaks an amount of the signal corresponding to the resistance of each resistor, even when the attenuation of each of the attenuators 3, 13 is maximized, it does not exceed the attenuation by the resistance of a single resistor R1.

Filed: 1992-04-11
Abstract: PURPOSE:To improve the sharpness of an image in a wet type image forming device. CONSTITUTION:A sharpness improvement device 33 which consists of a corona electrifying device similar in structure to a transfer device 13 is provided between a reverse roller 11 and a transfer device 13 and on the opposite side to a photosensitive drum concerning a transfer-sheet carrying path between them. Positive charges, opposite to the polarity of toner, are applied to the back of a transfer sheet 12 by corona electrification with the polarity opposite to that of toner charges applied by the sharpness improvement device 33. Consequently, toner whose bond with an electostatic latent image is weak is suspended in developer by the force of static electricity occurring by the positive charges on the back of the transfer sheet. In a toner image on the photosensitive drum which has passed the sharpness improvement device 33, the toner at the place when the bond is weak moves toward the place where the bond is strong by this suspension state, so that in the case of a character image, a character becomes thin. Because of this, the transfer image can be clearly shown. Namely, the sharpness of the image is improved.

Title: Cleaning of substrate
Inventor: SHITAYA KAZUHIRO
IPC: G11B7/26
Filed: 1988-05-18
Abstract: PURPOSE:To enable a stable supply of a substrate high in quality preventing the occurrence of stains by a method wherein the substrate is placed in an evaporation vessel as it is held sloping making its working surface face upward and pulled up from the vessel as it is also sloping. CONSTITUTION:A substrate 1 is placed in an evaporation vessel 5 making its surface face upward as it is held sloping for a final finishing process and pulled up from the vessel 5 as it is held in this state, which is dried up. The slope of the substrate 1 is so set as to make an angle of 15 deg.-50 deg. with a perpendicular line. Therefore, a cleaning fluid 2 containing a pollutant which stands in a hole is removed as the substrate is slanted, consequently a solvent film 4 formed in the evaporation vessel 5 contains no pollutant and moreover a condensate which flows inside the hole in the evaporation vessel is prevented from flowing outside to the working surface of the substrate 1 and standing in the hole. By these processes, stains caused by cleansing are prevented so as to supply a high quality substrate high in yield.
