Filed: 1994-12-27
Abstract: PURPOSE: To prevent the decomposition of a seed crystal and to execute seeding and crystal growing at a good yield by covering a seed crystal with a refractory bar and immersing the entire part of this seed crystal into a liquid sealant layer. CONSTITUTION: The raw material melt in a crucible arranged in a high-pressure vessel is covered with the liquid sealant layer 6 and a high-pressure inert gaseous atmosphere is maintained in this high-pressure vessel. The growth of the single crystal is executed by immersing the seed crystal 14 attached with the refractory cover 11 into the liquid sealant layer 6 and immersing the whole or a part of the refractory cover 11 thereinto at the time of immersing the seed crystal 14 into the raw material melt. The growth of the single crystal is executed by immersing not only the seed crystal 14 but the seed chuck 13 itself into the liquid sealant layer 6.

Patent JP-H03196630-A (JP)
Title: Manufacture of semiconductor device
Inventor: HARADA HIDEKI
IPC: H01L21/316
Filed: 1989-12-26
Abstract: PURPOSE:To optimize the difference in levels at the opening for contact formed at the interlayer insulating film on wiring by forming a wetting preventive film to solution, which includes a flattening material, on the film formed on a substrate, and patterning these with the same pattern so as to prevent the survival of the flattening material on the wiring. CONSTITUTION:As a wetting preventive film to solution, which includes a flattening material, remains on the film formed by patterning, even in case of applying solution to fill up the recess in the trace of removal of this film, the solution is repelled by the wetting preventive film 9. For this reason, the flattening film does not survive on the film 8b formed by patterning. Accordingly, in case of forming an interlayer insulating film 11 and forming an opening 11 for contact in this after filling the flattening material 10 in the recess at the surface of a board having wiring consisting of, for example, conductor film as the film 8b formed by patterning, only the interlayer insulating film 11 exists on the wiring. Hereby, the difference in level at the opening can be put in proper value only by adjusting the thickness of the interlayer insulating film whether the width of the winding is narrow or wide.

Abstract: PROBLEM TO BE SOLVED: To prevent a depositing material from staying and accumulating in the liquid compartment of a pump even if transfer liquid containing a depositing material such as slurry is used. SOLUTION: A barrier 7 such as an axially reciprocating bellows, diaphragm or the like is provided inside the pump body 1 so as to form a liquid compartment 9 between it and the inner wall 4a of the pump body 1. A suction opening 18 and a discharge opening 19 are provided on the inner wall 4a.

Title: Cylinder fuel injection type two-cycle engine
Inventor: FUJIMOTO HIROAKI
IPC: F02B23/10
Filed: 1991-11-27
Abstract: PURPOSE:To prevent exhaust gas from being deteriorated especially at the time of high load and high engine speed. CONSTITUTION:In a cylinder fuel injection type two-cycle engine which is provided with an exhaust valve 10 in a combustion chamber 5 and a fuel injection valve 9, the fuel injection valve 9 is arranged adjacent to the exhaust valve 10. Therefore, fuel which is injected inside the combustion chamber 5 at the time of high load and high engine speed is atomized or vaporized, so it is possible to prevent the exhaust gas from being degraded. Besides, because heat of/around the exhaust valve 10 is taken away, it is possible to prevent the exhaust valve 10 from being stuck.

Abstract: PROBLEM TO BE SOLVED: To obtain a high quality thin film of low resistance and low stress at a low cost by using gaseous neon as sputtering gas and jointly providing a cryopump and a turbo-molecular pump as exhausting apparatuses. SOLUTION: On the inside of a vacuum vessel 20, a target 10 and a substrate 12 are oppositely arranged, and the vacuum vessel 20 is fitted with two kinds of exhausting apparatuses of a cryopump 25 having a stop valve 26 and a turbo-molecular pump 23 having a stop valve 21. Moreover, neon as plasma discharge gas is fed from a bomb 22, its flow rate is controlled by a mass controller 24, and it is introduced into the vacuum vessel 20. Gaseous neon is exhaused mainly by the turbo-molecular pump 23, the pressure in the vacuum vessel 20 is held to a certain one by the balance of the exhausting performance between the mass flow controller 24 and the turbo-molecular pump 23, and the cryopump 25 exhausts oxygen, nitrogen, water vapor or the like and hardly exhausts gaseous neon. In this way, the flow rate of gaseous neon is made small, and the cost can be reduced.

On the other hand, a switch 54 is changed over to the 'H' side. The image data of the odd field which is the output of an ODD memory 14 is, therefore, outputted eventually to a post output terminal 60 of averaging processing by an averaging circuit 62. The image data of the odd field and the interpolation data based on the image data of the odd field by the averaging circuit 62 are outputted to a video printer when there is the motion in the images in such a manner. The field printing which is substantially free from the blurring of the moving parts is executed.

Abstract: PURPOSE:To constitute a distribution type thermosensible element so that a room temperature is caught uniformly on an average, the construction work is simple, the sensitivity is scarcely varied by the construction work method and material of the ceiling, and a fault scarcely occurs by forming the element by a thermosensible wire formed by twisting two pieces of metallic wires, and a substrate formed by a heat insulating material to which the thermosensible wire is fixed. CONSTITUTION:A metallic wire 2 whose regular filling is uniform is used instead of a hollow pipe so as to be manufactured easily, and in order to reduce a radio wave fault, two pieces of insulating wires are twisted and used. In order to eliminate the influence caused by a difference of materials of the ceiling and the wall and a difference of the adherence degrees, the thermosensible wire 2 is placed on a substrate 3 having a good heat insulating property, and an adhesive material 5 is applied to the reverse side of the substrate 3 so that the construc tion work is executed simply. In such a way, since the element itself is inexpensive, and also, the construction work is executed easily, the cost of construction work is low, and a temperature of the room is caught on an average, therefore, this element is suitable for air-conditioning, as well, and as for a fire sensor, unevenness of sensitivity caused by a difference of places in which a fire is generated is smaller than that of a spot type, and the element which is scarcely influenced by a difference of materials of the ceiling, and scarcely generates a fault is obtained.
