Title: Device for pulling up single crystal
Inventor: TAKANO KIYOTAKA
IPC: H01L21/208
Filed: 1992-02-04
Abstract: PURPOSE:To obtain a high-grade single crystal with good productivity and to provide a device for pulling up a single crystal capable of producing the product in high yield. CONSTITUTION:Polysilicon is continuously supplied to a melt 14 in a quartz crucible 3, and a single crystal 17 is grown by a device 1 for pulling up a single crystal. In this case, an upper ring 7 is set above the crucible 3 in a chamber 2, and a carbon cylinder 10 is extended from the upper to lower parts in the chamber 2, allowed to pierce the upper ring 7 and made freely movable in the vertical direction. The heat radiated from the surface of the melt 4 is reflected toward the crucible 3 again by the upper ring 7, the heat is not transmitted above the upper ring 7 due to its heat insulating effect, hence the space below the upper ring 7 in the chamber 2 is kept heated, the melt 14 is not solidified in the vicinity of a quartz partition wall 12 or in a raw material feed part, and the growth rate SE of the single crystal 17 is increased.

Title: Lead frame and semiconductor device using the same
Inventor: IWASA KENJI
IPC: H01L23/50
Filed: 1993-03-09
Abstract: PURPOSE:To reduce the thickness of a semiconductor device and ensure the strength of a lead frame, by thickening the outer part of the lead frame and thinning the inner part of the lead frame. CONSTITUTION:Lateral frames 1 which are formed in a continuous length type at the end portions in the longitudinal direction, and longitudinal frames 2 which are formed at constant intervals so as to be vertically connected with the lateral frames 1 are formed to be thick as compared with tabs 5 and inner leads 13 to which a semiconductor element are fixed. Hence a lead frame can sufficiently endure the handling in the process for manufacturing a semiconductor device in the state of lead frame, so that generation of defects like the bend of a lead frame which occurs during the manufacturing of a semiconductor device can be prevented. Since the inner lead part of a lead frame is thinnly formed, the total thickness of a semiconductor device can be reduced, and thin type packaging is enabled.

Title: Apparatus for producing single crystal
Inventor: KOGURE YASUHIRO
IPC: C30B15/20
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To increase the flow speed of the gas without increasing the flowing quantity and avoid a harmful effect attributable to the increase of a flow speed by surrounding a single crystal, which is pulled up from a fused liquid of a raw material according to the CZ-method, and allowing an inert gas to pass downward and swirl inside the surrounding body. SOLUTION: For pulling up a single crystal, the inside of a main chamber 1 is evacuated to vacuum, a heater 4 is controlled and a fused liquid 10 of silicon is formed in a crucible 3. A seed crystal attached at the lower end of a wire 8 hung down into the main chamber 1 from the inside of a pull chamber 2 is dipped in the fused liquid 10 in the crucible 3, and the wire 8 is lifted to pull up a single crystal 11. At this time, an inert gas Ar is introduced from the inside of the pull chamber 2 into the inside of the main chamber 1. The pulled-up single crystal 11 passes inside a heat- insulating cylindrical body 6 and is drawn into the pull chamber 2. The heat-insulating cylindrical body 6 blocks the transmission of radiant heat to control heat history of the single crystal 11.  Owing to spiral protrusions 7, 7,... formed on the inner surface of the heat insulating cylindrical body 6, the inert gas becomes a spiral flow, the flow speed is increased without increasing a flowing quantity, and accordingly pollutants in the fused liquid 10 is removed with the gas.

Title: Liquid supply controller for tank truck
Inventor: NAITOU KANEAKI
IPC: B60P3/22
Filed: 1980-04-11
Abstract: PURPOSE: To accomplish an efficient supply of liquid with a pump discharge pressure kept at a set level by controlling the revolutions of the engine related to a pump discharge pressure.  
     CONSTITUTION: A pump 2 is driven with an engine 1 to feed a liquid in a tank 3 to a feed hose 6 by way of a discharge tube 4. When the liquid is high in the viscosity and long in the supply distance, a part of the liquid is recirculated to a pump suction section through a relief valve 20 as the pump discharge pressure exceeds the set pressure. Under such a supply condition, a pump discharge pressure works on the rear surface of a piston of the second cylinder 17 by way a piping 19 so that a piston rod changes a change-over valve 14 to the right position against the force of a spring 18, allowing a liquid discharged from a pump 2 to flow into a tip chamber of the first cylinder through a branch pipe 15 thereby reducing the first cylinde 12. A control lever 7 is pulled back to lower the revolutions of the engine resulting in lowering in the discharge pressure.

Abstract: PROBLEM TO BE SOLVED: To obtain pottery in which colored potter's clay and argil are firmly adhered. SOLUTION: Commercial colored potter's clay is blended with a thermal property adjusting agent, that is one having coefficient of thermal expansion or heat shrinkage factor near to that of the argil, for example silica discharged as impurities when the argil is subjected to purification, water is added thereto and the mixture is kneaded to improve the colored potter's clay to one having coefficient of thermal expansion or heat shrinkage factor near to that of the argil. The improved colored potter's clay and the argil are bonded and calcined to produce a product. Since an adhesive consisting essentially of the argil and the colored potter's clay and mixed with glass powder, lime glaze, etc., is used, the pottery in which the improved colored potter's clay and the argil are firmly bonded can be obtained.  Further gorgeous pottery with beautiful patterns can be obtained by preparing the colored potter's clay with patterns in which one improved colored potter's clay or a plurality of improved colored potter's clay is blended with the argil and bonding the improved colored potter's clay to the argil.
