IPC: F41G3/26
Filed: 1990-11-27
Abstract: PURPOSE:To reduce a load on a calculator and to enable a real time simulation to be carried out to judge if a bullet accurately hits by a method wherein the hit is judged if a target is placed within a column with a line axis connecting a position of an initial bullet with a position of a final bullet continuously launched, and with an allowable tolerance as a radius. CONSTITUTION:A position B1(tk) at a time tk after a trigger for the bullets continuously launched and a position Bf(tk) of the final bullet are calculated, a linear line connecting the position B1(tk) of the initial bullet and the position B1(tk) of the final bullet is applied as an axis and a radius is an allowable tolerance R to form a column and it is judged hit if the target item is within the column. The aforesaid calculation is repeated from a time when a trigger is pulled to an appropriate time in which a position of a self plane, a position of an enemy plane and a speed of bullet are judged, thereby a presence or non-presence of the hit bullet when the trigger is once pulled can be judged. With such an arrangement, a calculation of a trajectory for about 100 bullets is carried out by the calculation for two bullets, resulting in that a load for a computer can be reduced and then a real time simulation regarding a presence or a non-presence of hit can be carried out.

IPC: G03B42/04
Filed: 1988-12-20
Abstract: PURPOSE:To prevent intensifying screens from interrupting the movement of a film by stretching out projecting parts which do not overlap with each other at the end parts of two pressing plates, stretching out similar projecting parts at the same position of the intensifying screens which come into contact with the pressing plates, providing lever means at positions corresponding to these projecting parts, and selecting a contacting condition between the intensifying screens and the pressing plates through the operation of these lever means. CONSTITUTION:The rear side pressing plate 13 is moved downward, and the levers 27 and 28 are moved or turned upward. Conversely the levers 21 and 25 are moved or turned downward, and a stopper 29 is moved or turned upward. Then the intensifying screens 16 and 17 are overlapped and inserted from the levers 22 and 23. Next, the levers 22 and 23 are moved toward an ejecting part while the lever 22 and the lever 23 are turned downward and upward, respectively, and the intensifying screens 16 and 17 are moved toward a fixed position to be photographed. Moreover, the levers 23, 27, and 28 are turned or moved downward and the projecting part 17a of the intensifying screen 17 is held by energizing it with respect to the projecting part of the rear side pressing plate 13. As a result, the intensifying screens 16 and 17 adhere to the pressing plates 12 and 13, respectively. Thus, the intensifying papers do not prevent the movement of a film.

IPC: H01L21/338
Filed: 1992-12-01
Abstract: PURPOSE:To obtain stable element characteristics when a substrate is thinned, by forming a silicide film of high-melting-point metal having tensile stress on the rear of a semiconductor substrate. CONSTITUTION:An active layer 2 is formed by implanting Si in a semi-insulating substrate 1 and heat-treating it. After a source electrode 3, a drain electrode 4, and a gate electrode 5 are formed on the active layer 2, the rear of the substrate 1 is mechanically polished by lapping. A WSi film 6 being a silicide film of high-melting-point metal and an Au film 7 are formed in order on the polished rear of the substrate 1 by sputtering or the like. The WSi film 6 is a thin film having suitable tensile stress for improving thermal conductivity. This kind of film may be a sllicide film of high-melting-point metal like Ti, Ta, Mo and Zr. Since the WSi film 6 is formed on the rear of the GaAs substrate 1, the warp of the GaAs substrate 1 can be sufficiently corrected in virtue of the film stress of the WSi film 6.

Title: Narrow gap arc welding method
Inventor: SUGITANI YUJI
IPC: B23K9/173
Filed: 1987-12-21
Abstract: PURPOSE:To form a bead with prescribed height even if gap width is changed by controlling the welding torch height position and the welding speed so as to maintain a preset welding current. CONSTITUTION:The actual torch height Y detected by a height position detector 131 such as a magnetic sensor is given to one end of a differential amplifier 132. On the other hand, the torch height Y0 preset properly by a torch height setter 133 is given to the other end of the differential amplifier 132. The differential amplifier 132 outputs the difference between such a reference value and a detected value, namely, the change of the torch height, Y-Y0=DELTAY and gives this differential output DELTAY to a comparator 134. On the other hand, a desired detection lower limit value of the torch height change set by a blind sector setter 135 is given to the comparator 134 and compared with the differential output DELTAY thereby. When the differential output DELTAY becomes higher than the lower limit value, a signal is sent to a microcomputer 136 which gives a control command to a driving driver 137 so that a detected signal of the torch height change DELTAY attains zero and based on said control command, the welding speed is controlled variably via a driving motor 136 of a feeder 6.

Title: Preparation of liquid crystal electro-optical device
Inventor: KONUMA TOSHIMITSU
IPC: G02F1/1337
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To obtain a liq. crystal electro-optical device enabling to easily controlling liq. crystal alignment and having a response rate, especially a high falling rate by forming a nematic liq. crystal having positive dielectric anisotropy between substrates by rubbing alignment film in an anti-parallel direction and specifying a pre-tilt angle of liq. crystal. SOLUTION: With alignment film rubbing in an anti-parallel direction, nematic liq. crystal having positive dielectric anisotropy is formed between a pair of substrate 51, 52 and, in this case, the liq. crystal molecule has a pre-tilt angle of <=40 deg.. Cholesteric (chiral nematic) liq. crystal can be used as the liq. crystal, however nematic liq crystal is pref. Further, [anti-parallel direction] means that rubbing directions to substrates form nearly 180 deg. as expressing in a fig. Accordingly a display using rotary power as convention can not be carried out, because the liq. crystal does not cause twisted alignment having an angle of 90 deg. as conventional. Therefore, a display is carried out by applying refractive index anisotropy of the liq. crystal.
