Title: Flattening treatment method
Inventor: TAWARA TAKASHI
IPC: H01L21/316
Filed: 1991-01-30
Abstract: PURPOSE:To prevent irregularity in an etching-back amount from becoming large even when a semiconductor wafer is left in the air after an SOG(spin-on- glass) film has been formed at a flattening treatment in which, after the SOG film has been formed on the surface of the semiconductor wafer so as to cover the stepped part and the like of an interconnection, the SOG film is etched back. CONSTITUTION:An SOG film 18 is formed in a silicon oxide film 18 with which interconnection layers 14A, 14B are covered. After that, before the SOG film 18 is etched back, it is baked at a comparatively low temperature (about 200 deg.C). Since the moisture in the SOG film 18 is removed by this baking treatment, a stable etching characteristic can be obtained at an etching-back operation after the baking treatment.

Title: Conduit for transferring abrasive in blasting device
Inventor: MASE KEIJI
IPC: B24C9/00
Filed: 1995-02-17
Abstract: PURPOSE: To enhance the ability to collect an abrasive into a collecting tank by allowing the abrasive injected inside a cabinet by a blasting device to be efficiently transferred inside a conduit by means of a current of air. CONSTITUTION: A main flow passage 15 is formed between an upper wall surface 11 and a straightening vane 14, and an auxiliary flow passage 16 is formed between a bottom wall surface 13 and the straightening vane 14. An inlet 17 leading from the main flow passage 15 to the auxiliary flow passage 16 is provided. Even if an abrasive flowing through the main flow passage 15 is raised along the surface of the straightening vane by a centrifugal force while under friction against the straightening vane, it leaves the upper end of the straightening vane 14, is thereby released from the friction against the straightening vane, and is transferred upward on a current of air from the auxiliary flow passage 16.  Since the amount of abrasive flowing to the auxiliary flow passage 16 via the inlet 17 is small as a whole and the action of the centrifugal force is weak, the abrasive does not remain on the bottom wall surface 13 but is efficiently transferred upward on the upward current of air inside the auxiliary flow passage.

Title: Method and device for drainage of guide vane leakage in a reversible hydraulic machine
Inventor: INAGAKI TAIZOU
IPC: F03B11/00
Filed: 1982-02-26
Abstract: PURPOSE:To cool a runner and prevent the depressing air in runner from leaking to the casing side by retaining proper the thickness of water film produced by the leak from guide vanes whether the runner rotates in the generating direction or the lifting. CONSTITUTION:The effect for drainage is set full by opening fully drainage valves 17, 18 installed at the drainage pipes 14, 15 simultaneously so as not to allow the leak water to intrude into the runner 2 during phase adjusting operation. During standby operation for lifting of water, on the contrary, either of the valves 17, 18 is opened fully, the other being held full closed, so as to prevent excessive drainage of guide vane leakage. Thus a proper water film required to prevent gas leakage can be retained at the interanl circumference of guide vanes as well as risk of unsufficient cooling for the runner eliminated.

Abstract: PURPOSE:To perform an operation for each of specified times strictly in accordance with set time by a method wherein a geared motor having a specified number of revolution is applied as a driving motor, any stopping time for every specified operating time is set to control a rotary hammering spacing time. CONSTITUTION:In case that eight geared motors are arranged in one waste heat boiler, operation of the eight geared motor is performed in series (I), the operation is performed in two independent series sets (II), the operation is performed such that a pair of two units are simultaneously energized to make an entire operation in series (III), a geared motor is applied as one in which 6 seconds are required for one rotation, its stopping time is made variable ranging from 0-999 seconds so as to make a proper setting through a timer, thereby the operation can be performed at any arbitrary time. With this arrangement, the incapability of operation due to a difference in inertia of hammer or energizing torque is not found and so operation for any time can always be carried out strictly in accordance with set time.

Title: Manufacture of resin molded form
Inventor: KOBAYASHI YUKIO
IPC: G02B3/08
Filed: 1992-02-18
Abstract: PURPOSE:To efficiently produce a resin molded form having a large uneven shape on a surface by using active energy beam curable composition. CONSTITUTION:A nickel stamper of a Fresnel lens shape is used as a mold, and active energy beam curable composition having a viscosity of 3-300mPa.s is spread. As a transparent filmlike base material, an easily adherent polyester film is used. It is reacted to be cured by irradiating with an ultraviolet ray by using a high-pressure mercury lamp. These mixtures do not particularly generate bubble when it is spread in a mold. The base material is superposed on the composition, and fretted with brushlike material formed of polyester single fiber from thereabove. When a thickness spot of the lens after it is cured with the ultraviolet ray is measured, it falls within a range of about + or -10mu from a designed value. Thus, a molded form having no entanglement of bubbles and excellent thickness accuracy is obtained.

Abstract: PURPOSE:To accomplish non-contact detection of the breakage of wire strands produced by a wire twister. CONSTITUTION:The number of wire strands during N-turns of the wire strand- rotating section R of a wire twister is detected in a non-contact manner for wire strands B by an optical system, and when such number gets smaller than a specified number, the wire twister is put to operational shutdown based on the determination that the wire strands have broken. Because of non-contact detection, wire strands are not damaged. On wire strands' breakage, the wire twister is put to immediate shutdown; both wire strands and wire twister will not be damaged, also leading to handling facilitation.
