Filed: 1993-02-15
Abstract: PURPOSE:To always accurately obtain a pellet having a predetermined shape by providing a control means increasing and decreasing the granulation speed of a pelletizer corresponding to the increase and decrease of the supply amt. of a supply mechanism. CONSTITUTION:When the amt. of the molten resin A supplied to a hopper 6 changes and the level in the hopper 6 changes, this change is detected by a sensor 17 and a control signal is sent to a supply mechanism 3 and a pelletizer 2 from a control box 18. That is, when the level in the hopper 6 lowers, the rotational speed of the motor 15 of a supply mechanism 3 is lowered to reduce the supply amt. of the resin to return the resin level in the hopper 6 to a predetermined amt. At the same time, the rotational speed of the motor 16 of the pelletizer 2 is lowered to alter a granulation speed in proportion to the reduction of the supply amt. When the resin level is raised, the reverse operation is performed.

Title: Fixing of gas-inlet pipe for vapor-phase growth apparatus
Inventor: TERAO HIROSHI
IPC: C30B25/14
Filed: 1985-02-13
Abstract: PURPOSE:To enable the fixing of a number of gas-introducing tubes in an extremely closed state, with simple operation, in one step, by fixing a plurality of O-rings and gas-introducing tubes simultaneously with an integrated O-ring- pressing member. CONSTITUTION:For example, five gas-introducing tubes 1 and five O-rings 2 are fixed to a fixing base 5 in one step with an integrated O-ring-pressing member 3. The pressing of the O-rings is carried out to enable the fixing of all the O-rings under equal forces with e.g. a large cap nut 4. Since a number of gas-introducing tubes are fixed at the same time with simple operation, the structure of a vapor-phase growth apparatus can be simplified. The performance of the apparatus can be improved by the reduction of useless space in the reaction vessel because a number of gas-introducing tubes are fixed in an extremely closed state.

IPC: B29D30/68
Filed: 1989-02-03
Abstract: PURPOSE:To improve the efficiency as well as the saving of power in the grinding work of a tire tread by a method wherein grinding is effected once or twice in accordance with the amount of remaining tread. CONSTITUTION:When the result of measurement (radius R of a tire 2) is sent from a measuring means 38, a control means 41 obtains a difference between the result of measurement and a predetermined finishing value and, thereafter, compares the difference with a set value. When the difference is lower than the set value, prestored one-time grinding program is called out and an one-time grinding signal is sent to servomotors 19, 20 through cables 42, 43. As a result, a rasp 28, rotated by the driving of another motor 29, is moved along the locus of one-time grinding. On the other hand, when the difference has exceeded the set value, a prestored two-time grinding program is called out and a two- time grinding signal is sent to the servomotors 19, 22. As a result, the rotating rasp 28 is reciprocated axially along the locus of two-time grinding whereby a tread 3 may be ground by two times reciprocally.

Filed: 1992-01-17
Abstract: PURPOSE:To improve sealing performance by providing a collar part of a seal material of a disc shape and elastically deformable in the periphery of a valve body and forming a collar part contact surface which this collar part makes contact with in the periphery of a valve seat at the time when a valve is closed. CONSTITUTION:Leakage is doubly prevented as a main seal part 3a seals a main valve seat 5a by way of making contact with it with pressure and forming a seal line as a circular projection 3c of a collar part 3b makes contact with a collar part contact surface 5b. When leakage is caused between the main seal part 3a and the main valve seat 5a, fluid pressure in a space between the collar part 3b and the collar part contact surface 5b becomes lower, fluid differential pressure is applied on the collar part 3b from left to right, the collar part 3b is pressurized on the collar part contact surface 5b, the circular projection 3c in an outer peripheral part makes strongly contact with the collar contact surface 5b and the strong seal line is formed. This sealing capacity becomes stronger as the fluid differential pressure becomes high. Consequently, sealing performance is improved.
