Title: Molding method of kneaded matter containing foamed glass particle
Inventor: MATSUMOTO HARUO
IPC: B29C45/47
Filed: 1996-10-10
Abstract: PROBLEM TO BE SOLVED: To realize a molding without damaging foamed glass particles by a method wherein a fusion kneaded matter is charged in the cylinder of a kneader and, under the state that its internal pressure is lowered by discharging an internally generated gas, foamed glass particles are fed in the kneader and kneaded uniformly so as to transfer the resultant kneaded matter in a mold for molding. SOLUTION: A predetermined amount of synthetic resin powdered or granular materials 11 is charged from a hopper 10 in the cylinder of a screw type kneader 12 and transferred successively along the groove of a screw to an outlet side. In this case, the synthetic resin powdered or granular materials 11 are melted through the heating of the cylinder and fusion frictional heat into a kneaded matter having the desired viscosity and density. By discharging moisture, gas and the like generating at that time through a deaerating port 13, the pressure within the cylinder is lowered, resulting in making the density of the kneaded matter smaller.  Next, a predetermined amount of the foamed glass particles in a hopper 14 is charged in the kneaded matter and uniformly dispersed by kneading so as to transfer the kneaded matter, which is brought under a desired kneaded state, in a mold 16 in order to obtain a desired molded body.

Title: Photo-cvd apparatus
Inventor: IHARA HISANORI
IPC: C23C16/48
Filed: 1988-12-06
Abstract: PURPOSE:To form a good-quality film on a substrate by providing a heating means of an alloy contg. mercury in the position opposite to the substrate in a reaction chamber. CONSTITUTION:The gaseous raw material introduced into the reaction chamber 8 forms a gaseous mixture with mercury vapor 10 from the alloy 6 contg. the mercury heated by a heater 7. This gaseous mixture is transported to the substrate 5 existing in the intermediate part where the gas is discharged from a discharge port 9 to the outside of the reaction chamber 8. The above-mentioned gaseous mixture causes a mercury-sensitized photochemical reaction by the incident light through window glass 2 from a light source 1 and generates a large amt. of the precursor of the deposits. The window glass 2 is disposed in the region where only the gaseous raw materials exist, exclusive of the region where the gaseous mixture flows and, therefore, the mercury-sensitized photochemical reaction does not take place and the deposits are not formed on the window glass 2 and in the region where the window glass 2 and the reaction chamber 8 come into contact with each other. The quantity of the light with which the gaseous mixture is irradiated is this maintained constant and, therefore, the deposition rate of the deposits to be deposited on the substrate 5 is stabilized and the good-quality film is formed.

IPC: E21B47/18
Filed: 1991-10-28
Abstract: PURPOSE: To prevent the separation of a motor housing and a drill bit. CONSTITUTION: The down-hole motor is rotated by drilling fluid pumped from the surface, through a passage formed within the drill string 10, and into the down-hole motor. A valve 36 is positioned in the passage in the drill string and has a first operating position adapted for passing the drilling fluid to the down-hole motor, and a second operating position adapted to substantially blocking the drilling fluid from being delivered through the down-hole motor. The valve is of a two piece construction, having a first body 44 connected to an upper tubular section 14 and a second body 46 connected to the down-hole motor. Longitudinal movement between the upper tubular section 14 and the down-hole motor is a result of rotation of the lower tubular section by the motor.  Corresponding longitudinal movement of the first and second bodies between the first and second operating position is generated by the longitudinal movement.
