Title: Method and apparatus for ultrasonic flaw detection
Inventor: AIKAWA YASUHIRO
IPC: G01N29/07
Filed: 1982-02-01
Abstract: PURPOSE:To improve the detecting accuracy of an echo outputted from a defective end part, by using two pairs of ultrasonic scew angle probes to receive and discriminate the echo of the defective end part from both sides of the defect. CONSTITUTION:Two pairs of synchronously controlled ultrasonic scew angle probes 1, 1' opposed through a surface defect 4 are put on the same surface of an specimen and a transmission pulse is simultaneously sent to them to receive echoes from the upper part of the defect 4 by the probes 1, 1'. The probes 1, 1' are moved so that the echoes from the end parts are located on the same position on the time axis of a cathode-ray tube and adjusted so that the beam ways W, W by the probes 1, 1' coincide with each other. Although the echoes are not clearly detected only by one probe, the echoes from the end parts are cleared by a composite effect obtained by overlapping and adding them. The depth (d) of the end part is determined from the distance (d) between the probes 1, 1' and the beam way length W under said status. The same manner is applied to the lower end part, so that the detecting accuracy of echo from the defective end part is improved.

Title: Method and tank for storing highly concentrated coal-water slurry
Inventor: ODA HIROSHI
IPC: C10L1/32
Filed: 1988-01-27
Abstract: PURPOSE:To prevent the compaction of a cargo due to the accumulation of dust coal for a long time, by providing a plurality of V-shaped grooves having the sides so inclined as to allow slurry sediment to flow down of itself in contact with one another in the sloping direction of the bottom of a tank. CONSTITUTION:Upon injection of highly concentrated coal-water mixture(CWM) by an injection nozzle 13, the dust coal accumulated in the root of a V-shaped groove 7 provided at the bottom of a storage tank is agitated and mixed with the CWM in the groove 7 and such mixture flows therethrough, drops into pits 8 and is pumped out of the tank. The CWM thus discharged is sent to a discharge pipe and the other substances are sent back into the storage tank. In this device, even a small amount of the sediment becomes greater in the height of its accumulation and the cross-sectional area of the groove is mush smaller than that of space on the same plane as the accumulated sediment. For this reason, the flow rate on the CWM and other sediment in the groove becomes greater and the characteristics of the agitation and removal of the sediment is improved.

Title: Rotary drier
Inventor: TAKIZAWA YOSHIHARU
IPC: H01L21/304
Filed: 1992-01-30
Abstract: PURPOSE:To not readhere a treatment fluid adhered to an inner wall to an object to be washed under influences of a rotary force of an air current by a method wherein the inner wall of a dry tub has such a structure that the treatment fluid does not form fluid drops. CONSTITUTION:A rotary table 3 and an object 1 to be washed are rotated, whereby air currents 11a, 11b, 11c generate within a dry tub 2. Here, a water- supplying material 10 is fitted into an inner wall of a drier 2, or a scattered treatment fluid forms a water film 8 by using a material having high wetness for the treatment fluid for the inner wall. Also, for instance, a netlike material is fitted into the inside of the inner wall to pass the treatment fluid through between the inner wall and the netlike material and to pass the air current 11c on the inside of the netlike material. Thus, a wind force from the air current is avoided, thereby preventing the water film from moving along the inner wall in the dry tub and preventing the treatment fluid from readhering to the object to be washed.

Filed: 1985-01-28
Abstract: PURPOSE:To improve the output characteristic with in the wide range of an engine by shifting the operation revolution speed range for an opening and closing valve for sub exhaust hole of a 2-cycle engine and an opening and closing valve for resonator chamber for exhaust pulsation. CONSTITUTION:A resonator chamber 18 is arranged contiguously in the vicinity of the port of the exhaust hole 6 of a 2-cycle engine, and an opening and closing valve 19 is installed into the connection part. A sub exhaust hole 15 is formed onto the both sides of the exhaust hole 6, and each opening and closing valve 16 is installed into the passages. The opening and closing valve 19 is closed at the first set revolution speed for the lower engine revolution speed, and the opening and closing valve 16 is opened at the second set revolution speed higher than the first set revolution speed. Since the opening and closing valve 16 is closed when the revolution speed is below the first set revolution speed, exhaust flows only from the opening 6, and blowing-bye is prevented, and the opening and closing valve 19 is opened to correspond to the exhaust pulsation at low speed. Over the first set revolution speed, the opening and closing valve 19 is closed, and over the second set revolution speed, the opening and closing valve 16 is opened to increase the exhaust at high speed.

Abstract: PROBLEM TO BE SOLVED: To enable a compact detector by utilizing a sliding part as a switch part as well i.e., combining a mass part with a movable contact together and arranging it to slide and come into contact with a fixed contact set on the inner side of a case. SOLUTION: While a car is travelling at a steady speed, a mass body 1 is pressed to the side of a second stopper 10 by the elasticity of a coil spring 6. At this time as fixed contacts 7 and 8 are not electrically connected with a movable contact 3, electric signals do not pass between terminals. When a car is collided, the freely-slidable mass body 1 is decelerated by a larger force than the elasticity of the coil spring 6 and moves to the side of a first stopper 9c. At this time when the mass body 1 moves, the contact lug 3a of the movable contact 3 is bent by the contact with the fixed contacts 7 and 8 and linearly slides remaining in the state of being in contact and bent. At this time as the fixed contacts 7 and 8 are continuously and electrically connected with the movable contact 3, the colligeon of the car is detected.
