Title: Gas-phase growth device
Inventor: BAN YUUZABUROU
IPC: C30B25/10
Filed: 1983-11-21
Abstract: PURPOSE:To obtain a titled device capable of growing a crystal having a composition almost identical with the supply ratio of each feed gas by providing a substrate heating device as a sufficient heat source for generating thermal convection in a crystal growth chamber. CONSTITUTION:A gold furnace 12 having sufficient length to generate a feed gas flow and thermal convection in a crystal growth chamber is provided. A gaseous hydride of III- or IV-group elements is introduced from an introducing pipe 5 and a gaseous organic compd. of II- or III-group elements from an introducing pipe 6, and both gases flow vertically downward in the crystal growth chamber. Thermal convection is formed from the vicinity of the site of a substrate 8 or below the substrate toward the feed gas introducing ports due to the installation of the gold furnace 12. Accordingly, each feed gas is gradually heated while flowing down from the vicinity of the introducing ports to the substrate 8, and even the feed gas having a low thermal decomposition efficiency is thermally decomposed with high efficiency at the surface of the substrate. The crystal having a composition almost identical with the supply ratio of each gas can be grown in this way. An infrared lamp and a high-frequency coil can be used as the heating device.

IPC: H04N7/08
Filed: 1986-09-19
Abstract: PURPOSE:To normally remove the posture of reception of the following reserved program even if a facsimile signal is interrupted during printing, by detecting the end of a picture signal during printing by not an end signal in the facsimile signal but an incorporated timer. CONSTITUTION:When a desired program number is detected, a flip flop 30 is set and a switch 21 is closed to wait for arrival of the picture signal. When the picture signal is detected by a picture signal detecting circuit 21, flip flops 31 and 32 are set and switches 28 and 22 are closed, and printing of the picture signal by a printer 16 is started. A timer 26 generates a pulse when a time obtained by adding a picture signal period t3 and an end period t4 elapses after the start of clock supply from an oscillator 24. When this pulse is generated, flip flops 30-32 are reset and switches 21-23 are opened, and printing of the picture signal by the printer 16 is stopped.

Title: Manufacture of semiconductor device
Inventor: FUJIEDA SHINJI
IPC: H01L29/78
Filed: 1988-08-31
Abstract: PURPOSE:To make it possible to improve the reproducibility of the manufacturing process of a MIS type semiconductor device by forming the surface of InP as the stabilized surface of P, and thereafter forming an insulator film. CONSTITUTION:The surface of InP at the initial state is made to be the stabilized surface of 2X1 or 2X4 of P. Thereafter, non-oxide based insulating film is formed. Of course, the step for removing a natural oxide film is performed by an epitaxial growing method of InP or heat treatment of an InP substrate in a phosphorus atmosphere so that the natural oxide film is not incorporated in the surface of the InP. In either case, an non-oxide based insulator comprising nitride, fluoride and the like is deposited as the insulator film at 350 deg.C or less. Thus the disappearance of the P from the surface of the InP is avoided. The oxide is removed because the deposition of the oxide causes the formation of the oxide film on the surface of the InP.

Sn and Al increase the strength and elongation, but in the case of less than the lower limit, the effect is insufficient, and in the case of more than the upper limit, the hot workability is deteriorated for Sn, and the castability is deteriorated for Al. Mg fixes S to be incorporated as stabilized MgS in a mother phase and improves the hot rollability, but in the case of less than the lower limit, the effect is insufficient, and in the case of more than the upper limit, the fluidity of the molten metal is deteriorated. Cr strengthens the grain boundaries in the ingot and improves the hot workability, but in the case of less than the lower limit, the effect is insufficient, and in the case of more than the upper limit, the castability is deteriorated.

Title: Workpiece feed device
Inventor: HAMAMOTO MUTSUO
IPC: B65H5/14
Filed: 1986-09-19
Abstract: PURPOSE:To make it possible to feed a supply material having a less rigidity without making into close contact with the contact surface of a feeder, by forming the workpiece contact surface of a gripper or a roller in a star-like shape, a concave and convex shape or a sand paper-like shape, so that the contact area between the workpiece contact surface and the workpiece is decreased. CONSTITUTION:In such a case that the workpiece feed device is a gripper, a workpiece 5 passing on the contact surface 2 of a cylinder body 1 is clamped by a movable piece 7, and is fed by a predetermined distance in association with the return motion of the cylinder rod. In this stage if the workpiece 5 has a less rigidity, although it cannot be fed being in close contact with the movable piece 7, it can be fed by the contact surface 2 having a star-like shape, a concave and convex shape or a sand paper-like shape. Further, even in a roll feed, if the contact surfaces 12, 14 are roughened in order to decrease the contact area between the contact surface of the clamp section and the workpiece, the workpiece 5 even having a less rigidity may be fed. Thus, it is possible to reduce the frictional resistance between the workpiece and the contact surface of the clamp section, thereby it is advantageous in the feed of a thin rubber or plastic sheet into a working station.
