Title: Vertical elongator in pipe forming plant
Inventor: MANFUREETO HIIN
IPC: B21B31/12
Filed: 1979-08-13
Abstract: PURPOSE: To simplify the removing work for the upper roll out of the machine at interchanging the roll, by installing the cradle to be integrated into one body with the roll chock for holding the upper roll in the lower cavity, with the device for 90° rotating the inverse T-type bolt in the topmost surface.  
     CONSTITUTION: When the roll is to be interchanged, the screw shaft 104 is pulled up to the specified position by the worm mechanism of the screw down device 103 installed on the freely detachable upper cover 102. Next, by retreating the rods of a pair of roll balancing cylinders 105, the roll chock 5 goes up while pushing up the vertical shaft 7, and stops when the shaft 7 strikes the shaft 104. Hereby, the bottom end of the inverse T-type bolt 1 installed on the cradle 4 enters the long hole 5a of the chock 5. Then, the bolt 1 is 90° rotated by the rotation device 2 in order to fasten the bolt 1 to the chock 5. Next, the rod of the cylinder 105 is jutted out, and the chock 5 becomes independent of the upper cover, so that the upper cover is removed away and the chock 5 including the upper roll 6 together with the cradle 4 in one body is taken out of the machine. On the other hand, the mounting work for the new upper roll is carried out in the reverse order to said procedures.

Abstract: PURPOSE:To determine freely corresponding relation between the movement of a hand and the movement of a marker, to make easy an input operation and to extend a menu area by setting optionally corresponding relation between an input area on a coordinate inputting device and a displaying area on a display screen. CONSTITUTION:When the coordinates of a point P1 in an area R1 are inputted from the coordinate inputting device, the coordinate position inputted from the corresponding relation with areas R1 and r1 is converted to a coordinate value P1, the marker is displayed at the position and the pattern processing instruction is executed. In the same way, when a point P2 in an area R2 is inputted, the coordinate position of the point P1 is converted to the point P2 of a display screen 12, the marker display is executed and the pattern processing instruction of the area R2 is executed. Consequently, when the coordinate information with high accuracy is to be inputted, for the area on the display screen, the coordinate input area is corresponded wider, many areas are to be established, and then, the area is made small up to the size of the extent in which the visible characteristic is not damaged.

Filed: 1993-04-28
Abstract: PURPOSE:To prevent a signal loss, deteriorated NF and deteriorated S/N by a resistance attenuator for impedance matching in the intermediate frequency amplifier circuit amplifying an output of a crystal filter with a transistor(TR) amplifier. CONSTITUTION:An output of a crystal filter 1 is inputted to a TR amplifier 3 via a tuning circuit 2 comprising a coil 21 and a capacitor 22. A current feedback resistor 31 and a voltage feedback resistor 32 are connected to a TR 7 and the resistance component of the impedance with respect to the crystal filter 1 is matched by selecting properly the resistance of the resistors 31,32. Moreover, the reactance component is matched by properly selecting an inductance of the coil 21 and a capacitance of the capacitor 22.

Title: Production of compound semiconductor single crystal and apparatus therefor
Inventor: OZAWA SHOICHI
IPC: C30B29/40
Filed: 1987-04-28
Abstract: PURPOSE:To contrive prevention of impurities from mixing in, by carrying out synthesis, seeding and single crystal growth of a compound semiconductor in the same apparatus using vertical coaxial arrangement of a cylindrical crucible having a slender tubular part at the bottom in an integrated process in a growth vessel by a vertical solidifying method. CONSTITUTION:A liquid stopping plug 51 and a seed crystal 53 are inserted into a tubular part (15a) at the bottom of a crucible so as to place the former in the upper part. A group III element 55 is simultaneously placed in a crucible 15 and a group V element 57 is placed in the lower vessel 25. The residual oxygen in a pressure vessel 11 is removed and replaced with an inert gas to adjust the interior of the pressure vessel 11 to a given pressure. Heating heaters 35 and 41 are then heated to advance synthetic reaction of a compound semiconductor of the group element 55 and group V element 57. The upper axis part 23 is then slowly lowered and the liquid stopping plug 51 is pulled from the tubular part (15a) and released into a melt 59. Since the liquid stopping plug has a lower specific gravity than that of the melt 59, it floats on the liquid surface to provide contact of the melt 59 with the seed crystal 53. The temperature of the contact part is then increased to remelt and make part of the seed crystal 53 compatible with the melt 59. Thereby a single crystal is grown by a vertical solidifying method.

Since P-N-P-N junctions are shaped toward the other surfaces from one surfaces in one part of each semiconductor board 3 and P-N-P-N junctions are formed in the direction opposite to said direction in other sections at that time, a section between the electrodes 1, 2 is brought to the conductive state even when any electrode is plus and any electrode is minus regarding voltage applied between a pair of the electrodes 1, 2. Accordingly, high withstanding voltage can be acquired, and trigger operation can easily be conducted.
