Inventor: DEBITSUDO KEI HOFUAATO
IPC: G06F17/22
Filed: 1993-04-13
Abstract: PURPOSE: To produce a text of a language which has more than 256 characters such 'as the Chinese and Japanese languages, etc., by collecting input stream of characters showing a prescribed language, dividing these streams into plural word groups and mapping these word groups to a unique string of single-byte characters which can be supplied to a selected text processing system. CONSTITUTION: An additional 'translation filter' 52, is added between a foreign language document text 50 and an indexing engine filter' 42. The filter 52 uses a special 'large-width character' function in order to process each character in two bytes regardless of presence or absence of English. Then the filter 52 decides the boundaries of words, decomposes a compound word if exists and inserts a special English equivalent word into a Japanese character stream before finally mapping a hex (hexadecimal) stream to an ASCII (single byte) stream. Thereafter, the ASCII stream is supplied to a 'normal' filter 42.

Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To suppress formation of a silicide on sidewalls which occurs, when ion implantation is performed for making silicon into amorphous form for suppressing thin wire effect. SOLUTION: After the formation of a gate electrode 14 and oxide film sidewalls 15, amorphous silicon layers 19a and 19b are respectively formed on the surfaces of the gate electrode 14 and a source drain region by implanting arsenic ions into the entire surface for making silicon into amorphous form at an energy of 40 keV and a dose of 3×1014 atoms/cm2. By conduction ion implantation, layers 20 having disturbed state oxide film structures are formed on the tops of the sidewalls 15 due to the ion implantation, but the layers 20 are removed through anisotropic etching, which is performed on the oxide film.  When a titanium film 17 is deposited over the whole surface, and after the film 17 is heat-treated for silicification and unreacted titanium is removed thereafter, a state results in which titanium silicide layers 18 are formed only on the gate electrode 14 and diffusion regions.

IPC: F24D3/16
Filed: 1988-05-02
Abstract: PURPOSE:To achieve a mild heating effect to the entire space of a room and reduce the heating cost by laying floor panels over heat insulating panels with floor beams inbetween, and disposing a heat generator in the space between the floor panels and heat insulating panels. CONSTITUTION:A pipe 14 is laid in serpentine to penetrate the end of respective floor beams through spaces G which are defined by neighboring floor beams 12, and the ends of the pipe 14 are connected to a heating device and an electric pump which automatically start and stop upon detecting the temperature of hot water flowing through the pipe 14.

Abstract: PURPOSE:To restrain discharge amounts of HC and CO in discharge gas in highland by reducing a control switch temperature to changeover control from open loop to feedback by a certain temperature when the running area of a car is decided to be higher than a fixed level. CONSTITUTION:When the temperature of cooling water detected by a water temperature sensor 59 is under a fixed control switch temperature (for instance 40 deg.C, air-fuel ratio is open loop controlled by a CPU51, and when over the control switch temperature, the air-fuel ratio is feedback controlled. In this device, the portion of height correction is obtained on the basis of the rate of difference between a theoretical air-fuel ratio and an actual one, and the height is known from the extent of this height correction. Then, whether the height is over a fixed value or not is decided. When the decision is YES, a control switch temperature at highland is set at a value lower than the above-said control switch temperature by a certain temperature (for instance at 20 deg.-30 deg.) for switching over control ratio between open loop and feedback to control air-fuel ratio.
