Title: Method for etching of polycrystal silicon
Inventor: AKASAKA YOUICHI
IPC: H01L21/306
Filed: 1978-10-30
Abstract: PURPOSE: To control precisely etching angle for a poly Si film by injecting ions enoughly and thinly on a surface of the poly Si film and then etching after the poly Si film was formed.  
     CONSTITUTION: After a poly silicon 31 was grown, a layer 31a of As, Sb, Ar etc. for ion injection is formed at close place before a picture plate is made. By so doing, the etching rate in the layer 31a becomes fast and the etching advances along an angle θ. The angle θ is determined by difference of the etching rate between the layers 31 and 31a, and if the injected amount of ions is selected appropreately to be more than 3×10 13 /cm 2 , it is possible to control precisely the etching angle of poly silicon and also to prevent disconnection. Further, it enables to reduce a sheet resistance of the poly silicon by driving the injected ions into the layer.

Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To provide such a data distributing system for an on-vehicle audio device as being capabel of realizing a proper sound field space for every type of vehicle without increasing the types of products. SOLUTION: Coefficient data for a vehicle 3 on which an on-vehicle audio device 1 can be mounted is previously found by using a coefficient data measuring system 9 and input to a host computer 5 to be accumulated on a filter coefficient data base 4.

Title: Method for correcting white dot defect of photomask and device therefor
Inventor: MORISHIGE YUKIO
IPC: G03F1/72
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of erroneous recognition of a defect correcting part by a defect inspecting device in a method for correcting the white dot defect of a photomask. SOLUTION: The white dot defect of the photomask is corrected by a laser CVD by using this method and by irradiating the desired position on a photomask substrate 7 in a gaseous raw material atmosphere with a laser beam. In a first step, a metallic first light shielding film 33 (Cr film) is deposited in the desired correction position by using a first gaseous raw material 32 (Cr(CO)6 ) for a gaseous raw material atmosphere. In a second step, the gaseous raw material atmosphere is switched with a second gaseous raw material 34 (TDMAT(tetrakisdimethylaminotitan)) and a second film 35 (TiN film) having an antireflection effect is deposited on the first light shielding film 33.  An another method, after the metallic light shielding films are formed by the laser CVD, an oxidative gas is adopted for the atmosphere and the film is irradiated with a laser beam, by which the surface of the light shielding film is denatured to an oxidized layer having the antireflection effect.

IPC: B65H5/06
Filed: 1989-05-26
Abstract: PURPOSE:To shorten a span of original conveying time by stopping an original at the specified position of an image exposing part, and driving a first driving system within at least partial time of exposure time for scan exposure, then making it perform at least a part of feeding operation of the next original. CONSTITUTION:In an original resting state at an image exposing part, scan exposure by an optical system at the side of a copying machine body is started. At this time, a next original is delivered by way of a feed roller 3 and an intermediate conveyor roller 5, and when an original tip run past an original passage detecting sensor 7, a detecting signal is outputted out of this sensor 7, and this original is stopped at the specified position by time counting of a timer, making it be stand-by. During the while, a feeding magnetic clutch K2 is on but a conveying magnetic clutch K1 is off. Consequently, the next original is fed by a low-speed conveying mode, and the tip is reached to the vicinity of the image exposing part and it is on standby. Consequently, original changing time is reduced.

Title: Tree search type vector quantizer
Inventor: KAMIMURA NAOHISA
IPC: H03M7/30
Filed: 1988-06-02
Abstract: PURPOSE:To decrease the number of distance calculation by providing a distance computing means to decide the presence and absence of a code book vector, for which it is not necessary to calculate a distance with an input vector. CONSTITUTION:A distance computing means 4 to input an input vector x' and to output a quantizing output (a) generates a distance dij=(y'i, y'j) between vectors concerning respective code book vectors y'l (l=1, 2,..., n) which are generated in respective nodes. Then, the generated distance dij between vectors is stored in a distance table storing means 3 between code book vectors. Next, with using the distance between code book vectors which is prepared when the code book is generated, it is decided whether the calculation of a distance between the input vector x' and each code book vector y'j is needed or not. Thus, since the necessity and unnecessity of the distance calculation between the input vector and code book vector can be decided, the number of the distance calculation can be reduced only by the unnecessary part and a quantizing speed can be improved.

Filed: 1986-06-12
Abstract: PURPOSE:To improve the working efficiency of a connection switch device by switching the connection among a programmable logic controller PLC, a numerical controller and a programming controller after switching a switch circuit via a changeover switch. CONSTITUTION:When a changeover switch 11 of a control panel 5 set at a remote place from a composite controller 3 is operated, the operating states of the switch 11 are transmitted to the control input terminals of switching elements 16 and 17 via inverters 18 and 19. Therefore, it is possible to set one of two elements 16 and 17 set in a switch device 10 at a low impedance with the other element set at a high impedance respectively with operation of the switch 11. For instance, the input terminal of an inverter 18 is grounded in case the element 16 set between a PLC 1 and a programming device 4 is set at a low impedance. Then the device 4 is connected to the PLC 1 after the element is set at a low impedance and signals are transmitted and received. While the element 17 is set at a low impedance when the switch 11 is switched adversely. Then the device 4 can be connected with a numerical controller 2.

Title: Process for treating hydrogen-chloride-containing waste gas
Inventor: SASAKI NORIHARU
IPC: B01D53/34
Filed: 1979-10-22
Abstract: PURPOSE: To efficently treat waste gas without the problems of posttreatment of waste water or fume by a method wherein a high-temperature, hydrogen-chloride- containing waste gas is brought into contact with slaked lime powder, then with sprayed slaked lime slurry so that the hydrogen-chloride gas is adsorbed.  
     CONSTITUTION: Hydrogen-chloride-containing waste gas discharged from an incinerator 1 is cooled to about 350°C by the cooling tower 2 and is guided into the reaction tower 3. In the tower 3, the waste gas is brought into contact with slaked lime powder supplied from the apray nozzle 7, whereby the hydrogen-chloride gas reacts with the slaked lime and produces calcium chloride powder. The treated gas  further contacts slaked lime slurry fed from the tank 8 and sprayed from the nozzle  10 in the tower 3. This causes the hydrogen chloride gas in the gas to be adsorbed  and formed into solid powder. The treated gas exits from the tower 3 and enters  the dust collector 11 where the reaction products are removed. The treated gas is  then discharged from the stack 13, via fan 12, to the air.
