Title: Exposing and diaphragm control device for camera
Inventor: OE HARUKI
IPC: G03B9/07
Filed: 1984-12-18
Abstract: PURPOSE:To make possible the compactification of a camera and to improve the accuracy of diaphragm control such as FM by providing an electromagnetic driving device and opening detention lever and releasing the detention by following up to the return operation of a plunger owing to the annihilation of the final pulse to return the open member to the home position. CONSTITUTION:A driving pulse P1 is outputted when a pulse generating circuit 70 starts operating in accordance with a shutter release. An electromagnet 9 is therefore intermittently operated by the driving pulse P1 to repeat the attraction operation of short intervals of a plunger 9b by which a ratchet claw 12 is moved back and forth. A shut detention lever 4 is turned gradually toward the right by such movement and the effect of the shut detention lever 14 while an open/shut spring 5 is charged. The open detention lever 6 is going to be turned to the right by a connecting lever 16 at every attraction of the plunger 9b but cannot follow up the same as said lever receives the effect of a delay governor 8 and the pulse interval is short. The detention of the open/shut lever 2 is therefore not released. The ratchet claw 12 is held while pulling the lever 4 when the zero pulses are gradually attained. The lever 2 opens the shutter vanes by the effect of the spring 5.

Title: Magnetic recording tape
Inventor: SHINOHARA KOICHI
IPC: G11B5/738
Filed: 1988-10-24
Abstract: PURPOSE:To obtain a good touch with a magnetic head, i.e. value preferable in both the size and shape of an envelope by disposing thin films on both surfaces and forming the thin film disposed on the side opposite to a thin ferromagnetic metallic film in such a manner as have plural cracks in the direction orthogonal with the sliding direction of the magnetic head. CONSTITUTION:The thin film 6 having the plural cracks in the direction orthogonal with the sliding direction of the magnetic head facing the thin ferromagnetic metallic film 3 in contact therewith is disposed to the side opposite to the thin ferromagnetic metallic film 3. The magnetic tape is, therefore, easily deformable along the curved surface of the magnetic head and the good touch is obtd.; in addition, the cracks are not orthogonal with the longitudinal direction of the tape and, therefore, the effect of intensifying the mechanical strength is not so much degraded. The effect of relieving a change of the shape is eventually substantially maintained. The good envelope output state by the good head touch and the repetitive use is assured with the thin-gaged tape of the both-face thin film type in this way.

Filed: 1985-11-28
Abstract: PURPOSE:To obtain the titled single crystal with less generation of defects in high yield by using a seed crystal having a specified facial azimuth to pull a single crystal, and cutting out a (001) face wafer in the direction inclined to the lifting shaft to an angle determined by the facial azimuth of the single crystal. CONSTITUTION:The III-V compd. semiconductor single crystal (e.g., GaAs, GaP, InAs, InP, etc.) is grown by a pull method to produce a single crystal for forming a (001) facial azimuth wafer. In the production, a seed crystal having (11l) (where l=1.5-4) facial azimuth by Miller indices is pulled up, and a (001) face wafer is cut out in the direction inclined to the lifting shaft to an angle determined by the facial azimuth of the single crystal. Since the twinning and formation of polycrystals are reduced, a single crystal is easily grown, the material loss is reduced, and the yield of (001) face wafers can be improved. Furthermore, the improvement of yield due to the decrease in defects caused by the local deposition of high-concn. impurities when the high-concn. impurities are added can be realized.

Filed: 1990-10-09
Abstract: PURPOSE: To uniformly etch a W metal layer on an Si substrate with a minimum micro loading operation by executing three etching processes through the use of prescribed gas chemicals. CONSTITUTION: The W layer 23 of a heat resistant metal is opened to an insulating film 13 on the Si substrate 10 and it is overlapped through the adhesive layer 22 of Ti. For etching the W layer 23 on the insulating film 13, about 70% of the W film 23 is considerably uniformly etching-removed in the flow of the mix gas of SF6 +O2 +He with 600-800miliTorr of total pressure, the excessive etching time of the shallow opening is set to be minimum and a micro loading operation is reduced in a first process. In a second process, an etching end point is precisely detected by measuring and integrating radiation with 772nm and 775nm of Cl2 by using the gas of SF6 +Cl2 +He with 600-800miliTorr of whole pressure so as to prevent excessive etching. In a third process, Ti22 is etching-removed faster than W by using Cl2 +He.  Thus, the W layer is removed from the whole surface of the Si substrate and the connection opening which is uniformly filled with the layer remains.
