Title: Transfer method of pattern
Inventor: GOTOU MINEO
IPC: G03F7/20
Filed: 1983-03-29
Abstract: PURPOSE:To improve pattern-forming efficiency, by using a pattern, which is formed so as to compensate the transfer distortion yielded on a wafer. CONSTITUTION:Cross marks for measuring are arranged on a mask at a constant interval. A pattern is transferred on a wafer 7, and the measuring mask is formed in this way. Then, the positions of the marks formed on the wafer 7 are measured by using an optical-wavelength measuring device utilizing laser light. Based on the measured transfer distortion, a transfer pattern is formed on a transfer mask 3. At this time, the data of the measured transfer distortion is interpolated. The amount of correction for every minute region, which is obtained by dividing the pattern in a mesh state, is computed by a computer. The position of the graphic data in the minute region is corrected by the amount of correction in every region. By using the corrected data formed in this way, a transfer pattern 3a is formed on the mask 3.

Title: Preparation of wooden tile
Inventor: YOSHIKAWA HIDEO
IPC: B44D5/00
Filed: 1988-03-07
Abstract: PURPOSE:To obtain the same texture as the surface of a tile made of pottery by developing a stain pattern, by polishing the substrate film of the chamfering part of a surface side peripheral edge part to a degree partially leaving the same to expose the ground surface and subsequently applying finish paint to the substrate film before drying speckles of pitch paint to forcibly spread the speckles. CONSTITUTION:The outer peripheral edge of a square wooden plate is polished to form a chamfering part 2 to the peripheral edge thereof on the surface side and substrate paint is subsequently applied to the square wooden plate 1. The substrate film 3 is polished to be removed so as to be partially left and the ground of the square wooden plate 1 is exposed. Succeedingly, coal tar pitch being pitch paint is uniformly sprayed to the whole of the surface of the plate 1 to scatter small granular speckles 4. Immediately, lacquer type clear paint being finish paint is applied to the whole of the surface by spraying. The speckles 4 are pressed to a certain degree by said finish film 5 to spread uniformly and becomes a light-colored stain pattern to be fixed. By adjusting the color of the substrate paint, the density of the pitch paint and the gloss of the finish paint, the atmosphere of a pottery tile can be expressed.

Title: Variable filter circuit
Inventor: YOKOYAMA KENJI
IPC: H03H11/12
Filed: 1982-03-30
Abstract: PURPOSE:To vary equivalently the capacitance of a capacitor with control of an attenuator and to vary the cut-off frequency, by combining the principle of an impedance scaler and the attenuator. CONSTITUTION:An input signal is applied through a terminal of a resistance R and applied to an attenuator 3 via a buffer amplifier 2. The output of the attenuator 3 is connected to the output side of the resistance R from a buffer amplifier 4 via a capacitor C. Then an output is extracted out of the amplifier 2. The cut-off frequency (fc) is lowered less as A is reduced (as the attenuation quantity of the attenuator 3 approximates to -infinity ) and set at the minimum value fc=1/2piCR when A=0 is satisfied. While the frequency (fc) becomes higher as the A increases (as the attenuation quantity of the attenuator 3 gets close to 0), and fc=infinity  is satisfied in the case of A=0.

Title: Fixing device
Inventor: TAKAHASHI MASARU
IPC: G03G15/20
Filed: 1989-03-08
Abstract: PURPOSE:To prevent a serious scratch from remaining in a fixing part by detecting the abnormality near the fixing part before the temperature of the fixing part becomes abnormally high. CONSTITUTION:The fixing device is provided with a power supply interrupting means 13 which interrupts power supply to a heater 6 when the temperature of the fixing part is detected as rising to first temperature and an auxiliary temperature fuse 16 which fuses when the detected temperature rises to second temperature that is lower than the first temperature. When the auxiliary temperature fuse 16 is fused, a thermister 12 judges whether it is normal or abnormal based on information from a sequence control part 11. If it is normal, a printer maintains to work normally. When it is judged that the abnormality occurs, an indication that abnormality occurs, an indication that the abnormality occurs is displayed, and simultaneously, the action of the printer stops and the heater 6 is turned to off. Therefore, the fixing part is prevented from being damaged when the temperature of the fixing part rises to a high level.

Title: Flexible tube for feeding consumable electrode in arc welding
Inventor: KOTANI TAMOTSU
IPC: B23K9/12
Filed: 1980-04-25
Abstract: PURPOSE: To feed a wire smoothly for a long time by making the inner diameter of outlet end of a flexible tube that feeds the wire greater than the inner diameter of inlet end.  
     CONSTITUTION: In arc welding, inner diameter of the inlet end 2 of a flexible guide tube 1 made of nylon or fluororesin etc. that feeds the wire of a consumable electrode to a welding torch is made smallest and inner diameter of an outlet end 3 is made largest. Taper is given to the inner diameter so as to make the inner diameter successively greater from the inlet end 2 to the outlet end 3. Accordingly, a damage done by the wire to the inner wall of said tube 1 is reduced, and even when dust or chips of wire and plastics are accumulated in said tube 1, the inner wall of the tube 1 is not narrowed easily. Since the nearer to the outlet end 3 where the sending out force is weak, the larger the inner diameter, smooth feed of the wire is ensured without giving resistance to the wire.

Abstract: PURPOSE:To speed up search processing on an array table by providing the information to each table data for calculation of the area range of the table data having the same value as the corresponding data. CONSTITUTION:A searcher contains the search engines SE10 connected in series and each engine SE10 is connected to a search table buffer. The information on the minimum and maximum addresses of the search table supplied through search range output lines NXTMIN40 and NXTMAX41 of the SE10 set higher by a rank are received by a MIN 30 and MAX 31 respectively.

An arithmetic circuit 21 calculates mins (k, T) and maxs (k, T) when the coincidence is obtained from comparison of a comparator 22 and delivers them through OUTPUT 45. If no coincidence is obtained through the comparator 22, both minimum and maximum addresses of the search range are calculated and transferred to the MIN 30 and MAX 31 of the SE 10 set lower by a rank through the NXTMIN40 and NXTMAX41.
