Patent JP-2000091565-A (JP)
Title: Manufacture of semiconductor device
Inventor: KUBO HIROTOSHI
IPC: H01L21/336
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To save labor in a manufacturing process and greatly reduce the manufacturing cost by omitting a photomask process which was necessary for forming a thick oxide film and a source region. SOLUTION: In this method, after a gate electrode 13 is formed selectively, a channel region 16 and an impurity diffused region 17A are formed and an NSG film 15A is further formed over the entire surface, and a source region is formed by dividing the impurity diffused region 17A into parts at the same time as with formation of a gate contact 0P. Therefore, the photomask process which was necessary for forming a source region can be eliminated. Therefore, a photomask is required in only three processes of formation of a patterning mask for forming a gate electrode, formation for forming an opening 0P for making contact with a gate electrode (formation of a recessed part 0B1 for forming a source region) and the mask formation for patterning a wiring layer. Since only three photomasks need to be used in all in this way, a mask process and a process involved therein can be eliminated.

Title: Method and device for font data management and storage medium
Inventor: AMAMIYA CHIE
IPC: G06F17/24
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To provide the font data managing method in which character information, that is only effective for a certain specified user, is outputted. SOLUTION: A specified user is designated, a disired font is selected and it is discriminated whether the selected font is corrected in accordance with a specific product or not (steps S1 to S3). If it is not a specific product corrected font, it is moved to an output process, since any users are able to output it. If it is the specific product corrected font, it is discriminated whether it is the corrected font for a designated user or not (step S4). If it is not a corrected font for a designated user, the designated user is not able to output and the process stops. On the other hand, if it is the corrected font for a designated user, an output process is conducted (step S5). After the output process is completed, the file, in which all character patterns are generated, is outputted (step S6).

Title: Method and device for image pickup/reproduction
Inventor: HIEDA TERUO
IPC: H04N9/79
Filed: 1984-12-03
Abstract: PURPOSE:To reproduce the natural color by reproducing the color temperature of a light source at photographing as the illumination light. CONSTITUTION:A TV camera 1 detects the color temperature of the illumination light that illuminates an object to be photographed, and outputs is as a color temperature signal in addition to a TV signal. A photographing signal processing circuit does not process the white balance as is obtained in a conventional way, and R, G, B components are expressed in the TV signal in the original ratio. VTR12 records the TV signal from the TV camera 1 as in a conventional way, but at the same time it records the color temperature signal sent from the TV camera 1. VTR23 reproduces the TV signal and color temperature signal recorded on the tape, and displays the TV signal on a TV monitor 4 and sends the color temperature signal to a light source drive device 5. The light source drive device 5 converts the color temperature signal basing on the ratio of R, G, B and amplifies the power to obtain the necessary light source. A light source 6 is turned on by the output of the light source drive device 5, and reproduce the light which has the same color temperature used at photographing.

Title: Parallel connection body of gate-turn-off thyristor
Inventor: SENDA KATSUNORI
IPC: H03K17/73
Filed: 1987-10-08
Abstract: PURPOSE:To prevent turn-off switching near the safe operation region by connecting a capacitor in place of a short-circuiting jumper or between the short-circuiting jumpers to lower the unbalanced current of the gate-turn-off thyeistor(GTO) in a transient and normal operation. CONSTITUTION:A capacitor 8 is connected in place of the short-circuiting jumpers or between the short-circuiting jumpers. Two GTOs 7, 7' are connected in parallel between terminals A, K, for example, respectively in the same direction, and the gates of the GTOs 7, 7' are connected together via the capacitor 8, respectively. Even when there is a difference in the gate potential voltage, the gate current is received/supplied only in the transient state of the GTO via the capacitor 8 and the reception/supply of the gate current in the steady- state when the GTO is turned on is not enabled. Thus, the current unbalance at transient and steady-state operation of the GTO is suppressed lower, and the turn-off switching near the safe operation region is prevented.

Title: Liquefaction of cellulosic biomass
Inventor: MURAKI EINOSUKE
IPC: C10G1/00
Filed: 1988-10-07
Abstract: PURPOSE:To liquefy a cellulosic biomass without using a high-pressure reducing gas or inert gas by thermal decomposition of a cellulosic biomass in a pressure vessel in the presence of an organic solvent at temperature and pressure respectively higher than the critical temperature and critical pressure of this solvent. CONSTITUTION:A cellulosic biomass (e. g., pulp or wood flour) is thermally decomposed in a pressure vessel in the presence of an organic solvent (e. g., acetone or methanol) at temperature and pressure respectively higher than the critical temperature and critical pressure of this solvent. It is desirable to incorporate a small amount of a carbonaceous substance (e. g., activated charcoal) into this reaction system since the thermal decomposition temperature can be lowered thereby. By this technique, a cellulosic biomass can be liquefied without using a high-pressure reducing gas or inert gas. The raw material cellulosic biomass does not generate gas, such as CO2, in thermal decomposition, and the cellulose component can be liquefied completely. Further, since the decomposition product is a solution in an organic solvent, it can be used directly as a low-viscosity liquid fuel, etc., after the removal of the insoluble matter comprising, e. g., a carbonaceous substance and lignin.
