Title: Apparatus for production of silicon single crystal
Inventor: IWASAKI TOSHIO
IPC: C30B15/14
Filed: 1993-03-22
Abstract: PURPOSE:To obtain high quality by providing a cooling cylinder arranged around a single crystal of the prescribed apparatus with a moving mechanism for operating opening and closing angles and blowing an inert gas between this cooling cylinder and the single crystal, thereby adjusting cooling. CONSTITUTION:A seed crystal 12 mounted at the front end of a pulling up wire 14 is immersed into a melt 9 obtd. by loading a raw material, such as polycrystalline Si, into a quartz crucible 4 and melting this material with a heater 5 and is pulled up while the crucible 4 and the seed crystal 12 are kept rotated, by which a single crystal ingot 10 is grown at the bottom end of the seed crystal 12. Ar or the like is admitted from an inert gas introducing port 15 on the wall surface of a pulling up chamber 2b to form gaseous flow in the spacing between the inner peripheral surface, etc., of the cooling cylinder 21 and the ingot 10 from the chamber 2b. This gaseous flow is then regulated by operating the moving mechanism for the opening and closing angles of a hoisting type consisting of the cooling cylinders 21a to c, by which the silicon single crystal is produced while the heat history of the single crystal is controlled.

Title: Method and device for controlling driving shaft of industrial robot
Inventor: HOSOI HAJIME
IPC: B25J19/06
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To restrain a load to be applied to a collided arm and a driving system by generating the reverse torque in a driving shaft motor at the time when a command position is changed to an avoiding position extracted among a position data group. SOLUTION: When a position memory buffer 18 receives the collision generating signal 19 from a collision detecting device 7, the buffer 18 computes the speed of a servo motor 1 immediately before the collision on the basis of the stored position data group. Continuously, on the basis of the computed speed immediately before the collision of the servo motor 1, a decision whether or not a position data several seconds before the collision is selected as an avoiding position is performed. A command position generating device 10 outputs the avoiding position input from a command position changing device 9 to a position control device 6 as a command position when a collision is detected. With this structure, the reverse torque is generated in the servo motor 1 so as to stop the arm after instantaneously moving the arm to the avoiding position.

Title: Manufacture of lead frame with less working strain and metal mold used therefor
Inventor: NAKAGAWA KUNIO
IPC: H01L23/50
Filed: 1987-03-17
Abstract: PURPOSE:To prevent leads from shifting and tabs from shifting by applying in advance a working strain to at least part of a material to be punched off, and then pressing it in a predetermined pattern. CONSTITUTION:A metal mold has at a stopper 3 a protrusion 4 on a flat surface opposed to a material 5, and the protrusion 4 is disposed corresponding to at least part of a material 5 to be punched off. A working strain is applied in advance to at least part of the lead frame material 5 to be punched off to be pressed. The working strain at the time of pressing can be reduced by the remaining stress of the working strain applied in advance, and even if it is heated in an actual step, it can press it with less leads and tabs shifting.

Title: Apparatus for production of silicon single crystal
Inventor: AKASHI YOSHIHIRO
IPC: C30B15/02
Filed: 1993-03-22
Abstract: PURPOSE:To provide an apparatus for production of a single crystal which eliminates the contact of a solid layer and the single crystal and can prevent the degradation in quality. CONSTITUTION:The upper wall of a chamber 1 is pendently provided with a cylinder 14 of the diameter approximately equal to the diameter of a pull chamber 2 toward a crucible 3. Further, the upper part of the side wall of the chamber 1 is disposed with a discharge port 15 in a position higher than the top end of a heater 4. The gases in the chamber 1 are is charged by a pump, not shown in Fig., from the discharge port 15. An inert gas, such as Ar, supplied from the upper part of the apparatus descends down to the surface of a melt liquid layer 22 by passing the inside of the cylinder 14 and contains evaporating gaseous SiO. These gases are discharged from the discharge port 15 by passing the part above the heater 4. As a result, the evaporated gaseous SiO from the melt liquid layer 22 hardly passes near the heater 4 any more and, therefore, the phenomenon that the heater 4 is eroded by the reaction with the evaporated gaseous SiO is drastically lessened.

Title: Solenoid valve
Inventor: KANAMORI HIROYASU
IPC: F02M51/00
Filed: 1990-03-13
Abstract: PURPOSE:To check natural shutoff of a needle valve so as to force-feed high pressure fluid without hindrance by forming the first passage, which is hut off by the needle valve which is seated by the current application to a solenoid, and the second passage, which communicates a needle back pressure chamber with a pump return passage and is provided with a throttle. CONSTITUTION:When a plunger 26 rises by the rotation of a cam and fuel is force-fed during nonapplication of a current to a solenoid 9, the fuel inside a pump chamber 27 flows in the order of a passage 8 a valve chamber 5   the first passage 14  a needle back pressure chamber 10   the second passage 15   the small diameter passage 16a of a one-way orifice   a pump return passage 28. At this time, pressure is generated by the throttle effect at the time of fuel flowing in the space between a needle valve 4 and a valve seat 6 inside a pump chamber 27, and this becomes the valve closing force, and pushes the valve 4. But, by the throttle action of one-way orifice 16 shutting off the passage 15 and circulating the fuel from the passage, the fuel pressure inside the back pressure chamber 10 rises, and acts on the valve 4 as valve opening force. Accordingly, by selecting the diameter of the passage 16a so that it may cause proper throttling action, the valve closing force can be weakened.

Title: Video signal processor
Inventor: NISHIKAWA YASUSHI
IPC: H04N5/21
Filed: 1983-04-07
Abstract: PURPOSE:To obtain a noise-free luminance signal by mixing the output of a low- frequency passing type filter which allows only the low-frequency component of a luminance signal to pass with the output of a high-frequency passing type filter which allows only the high-frequency component to pass. CONSTITUTION:For example, the luminance signal A which has a noise at a horizontal blanking period part is inputted to a luminance signal input terminal 1. A switch circuit 3 allows only the horizontal scanning period part of the luminance signal A to pass and supplies it to the high-pass filter 4. Therefore, the output B of the high-pass filter 4 consists of only the information signal in the horizontal scanning period part of the luminance signal A. The luminance signal A, on the other hand, is supplied to the low-pass filter 5 to obtain a pulse signal synchronizing with a horizontal scanning period. The output C of the low-pass filter 5 and the output B of the high-pass filter 4 are summed up by an adder 6 to obtain the original luminance signal, which excludes the noise present at the horizontal blanking period part.

Abstract: PURPOSE:To improve the watertight quality of a terminal box, by using an elastic macromolecular sealing material for the lead-wire lead part of a hollow structure (the terminal box), and by filling a filler into the terminal box in order to supporting the elastic macromolecular sealing material. CONSTITUTION:A terminal wiring 901 is exposed to the outside, and thereto, a lead wire 907 passed through an NBR elastic macromolecular sealing material 902 is soldered. From the opposite side to the terminal wiring 901, a terminal box 903 formed out of polycarbonate is fitted in a slid way on the lead wire 907. Then, the terminal box 903 is crimped sufficiently, and is stuck on a steel sheet.
