Title: Manufacture of semiconductor integrated circuit device
Inventor: FUKUNAGA SHINOBU
IPC: H01L21/301
Filed: 1987-09-14
Abstract: PURPOSE:To realize a face-down mounting in a high yield by anisotropically wet etching a scribing region of a silicon wafer, selectively oxidizing the etched region, and dividing it by the scribing region. CONSTITUTION:A legion except a scribing region 2 and a region 3 for forming a field oxide film is covered with an Si3N4 film on a single-crystal silicon substrate 1 exposed in a plane (100) on the surface. Then, the substrate 1 is anisotropically wet etched with an alkaline etchant. When it is sufficiently anisotropically etched, an etching pattern 6 having a V-shaped groove of a section having a plane (111) on its side is obtained. Since the positional accuracy of a self-stopping point (a) is determined by the silicon crystal, it is extremely accurate. Then, when the substrate is oxidized, SiO2 films 7, 8 are formed, the film 7 formed on a scribing region is operated later as an insulating film upon contacting at the time of face-down mounting.

Title: Shutter device
Inventor: WASHISU KOICHI
IPC: G03B7/097
Filed: 1991-09-10
Abstract: PURPOSE:To restrain cost from increasing and to detect the moving direction of a shutter blade by making the width or the length of the slit of the slit plate of an incremental encoder different at every position of the slit. CONSTITUTION:Only one of the slits 311 penetrating a position display board 310 is made larger in size (length) to be constructed as the slit 11. Then, the slit 11 corresponds to a state where an aperture by the shutter blade becomes small (it is stopped down). By changing the pulse output of the incremental encoder in accordance with the aperture amount of the shutter blade and counting the pulse of the incremental encoder, the aperture amount is detected. By comparing the magnitude of each pulse output, the driving direction of the shutter blade is detected. Therefore, the shutter blade is held in a state where the shutter blade is stopped. Thus, a picture where not only an object but also a background are brought into focus is taken.

Filed: 1982-12-24
Abstract: PURPOSE:To prevent an engine stall even when numbers stored in a nonvolatile memory are abnormal by controlling the engine with standard numbers within a predetermined range when some numbers are outside the predetermined value at the time of engine restarting. CONSTITUTION:An electronic control circuit 25 of an engine consists of RAM 28, ROM 27 and MPU 26 etc. ROM 27 memorizes a control program etc. At the time of an engine restart, a judgment is made as to whether numbers representing engine operating conditions which are stored in the non-volatile ROM 28 are within a predetermined range. If some numbers are outside the predetermined value, standard numbers within the predetermined range are used to control. Thus, an engine stall can be prevented even when numbers stored in the non- volatile memory are abnormal.

Title: Gas-sealed shock absorbing member
Inventor: BUORUFUGANGU KATSUTSU
IPC: F16F9/02
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To start return process perfectly independently on return process of a press ram. SOLUTION: A concerted valve is an operable two-way changeover valve which is opened while a piston 20 descends (feeding process) for flowing oil from an oil tank to a circular space 45. The valve is closed when the piston 20 reaches a bottom dead center, preventing the contraflow of the oil from the circular space to the oil tank. The piston 20 is thus held at the bottom dead center. When the valve is opened again, contraflow of the oil occurs from the circular space 45 to the oil tank. The piston 20 returns to a top dead center as the result of shock absorbing function of gas.

Title: Laser amplifier
Inventor: KITA HIDEKI
IPC: H01S3/081
Filed: 1990-08-30
Abstract: PURPOSE:To fully utilize the energy of an excited laser medium and to obtain the output of a laser beam whose beam intensity distribution is uniform by a method wherein passage paths of the laser beam are not overlapped inside an excitation region and a prescribed reversion optical system is installed additionally in a halfway part of the light path of the laser beam. CONSTITUTION:A first concave lens and a second concave lens 8, 9 as reversion optical systems are installed additionally in the light path of a laser beam reaching the lower-part mirror of a plane mirror 7 from the lower-part mirror of a plane mirror 6. In this case, the laser beam which has been once passed from the right to the left inside an excitation region 2 is condensed by using the first concave lens 8 and is again dispersed. During this process, the intensity distribution inside the beam is reversed. The laser beam whose intensity distribution has been reversed is returned to a parallel beam by using the second concave lens 9; it is reflected by the plane mirror 7; this time, it is passed from the left to the right inside the excitation region 2; it is reflected additionally by the upper-part mirror of the plane mirror 6; it is taken out as a radiant laser beam 5. Out of beams of the laser beam which is passed backward and forward inside the excitation region 2, a part which has been passed through the position of a high gain at the going route is passed through the position of a low gain at the returning route. As a result, the distribution of an energy from the laser medium out of the beams is made uniform, and the lack of uniformity of the beam intensity distribution of the radiant laser beam 5 is relaxed.

The tip side of the air bag 24 is folded back plural times, and is formed as a lump-shaped layered part 24e, and the rear surface side of this layered part 24e is covered with base cloth 24h. Therefore, when the inflator 28 is actuated and gas is generated, this gas pressure advances the layered part 24e still in a lump shape through the base cloth 24h, and opens the lid 26 by this advancing pressure. Since the layered part 24e advances in a lump shape, this advancing speed is small, so that opening speed of the lid 26 becomes proper speed.
