Abstract: PURPOSE:To permit to detect the level of hot-water accurately and highly reliably by a method wherein a plurality of thermistors are conducted so as to maintain a reference temperature, higher than the temperature of hot-water in a bathtub under a condition that they are not submerged into the hot-water of the bath, at all times. CONSTITUTION:A horizontal communicating pipe 15 is taken out of the bottom section of the bathtub 7 and a side tube 17 is established from the tip end thereof upwardly. The thermistors S1, S2, S3 for detecting hot-water level, provided in the side tube 17 with proper intervals, are for detecting the levels of high-temperature hot-water, a middle temperature hot-water and low- temperature hot-water sequentially from the upper thermistor.

When respective thermistors are submerged in the hot-water of the bath of about 40 deg.C, they detect temperatures lower than the temperature under non-sumberged conditions of them and detect that the level of the hot-water of bath has arrived at the positions of respective thermistors S1, S2, S3, S0. Accordingly, the highly reliable hot-water level detection may be effected.

Filed: 1989-01-31
Abstract: PURPOSE:To facilitate tightening of a cap part by chamfering a part where a locking projection provided in a position in which the cap part corresponds to a bottle main body begins to mesh with a ratchet gear part. CONSTITUTION:The locking projection 4 is provided in the position in which the cap part 5 corresponds to the bottle main body 1. The part where the locking projection 4 begins to mesh with the ratchet gear part 8 is chamfered. When the cap part 5 is tightened to the opening of the bottle main body 1, the locking projection 4 begins to mesh with the ratchet gear part 8. However, the meshing weakens in tightening because the part where the locking projection 4 begins to mesh wit the ratchet gear part 8 is chamfered. Consequently, tightening of the cap is facilitated.

Title: Flaw detection of wire material
Inventor: MIYAZAWA ICHIRO
IPC: G01N29/04
Filed: 1987-02-03
Abstract: PURPOSE:To eliminate not only the generation of noise due to the adhesion of foreign matter to a wire material but also the seizure due to the adhesion of moisture to the wire material, by arranging a wire drawing roller die and a correction roll on one straight line and providing an eddy current flaw detection probe and an ultrasonic flaw detection probe between them. CONSTITUTION:A send-in apparatus 200, a correction apparatus 300, a roller die 400, and eddy current flaw detection apparatus 500, an ultrasonic flaw detection apparatus 600, a correction roll 700 and a marker 800 are provided on a machine stand 100 so as to be arranged on one straight line. A wire material 1 is fed by the send-in apparatus 200 and reduced in is diameter by the roller die 400. After the surface flaw and internal flaw of the wire material 1 are detected by the eddy current flaw detection apparatus 500 and the ultrasonic flaw detection apparatus 600, the wire material 1 is passed through the correction roll 700. By this constitution, since it becomes unnecessary to adhere a lubricating powder to the surface of the wire material 1, the generation of noise in eddy current flaw detection can be prevented and, even when moisture is adhered to the wire material 1 in ultrasonic flaw detection, no seizure trouble is generated.
