Title: Method and device for freezing
Inventor: ICHIKAWA MICHINORI
IPC: G01N1/28
Filed: 1989-12-30
Abstract: PURPOSE:To easily expand the freezing area of amorphous ice greatly by cooling a sample body which is made of liquid or a solid body, etc., containing liquid abruptly right after irradiating the sample body with an electromagnetic wave. CONSTITUTION:A cooling part for cooling the sample body 7 abruptly is arranged below a plunger 1 and a dewer 2 which is filled with a refrigerant 21 and a copper block 3 which has a flat top surface cooled with the refrigerant 21 are provided. When the plunger 1 falls, the sample 7 on the tip of the plunger collides against the copper block 3, but its shock is relaxed by dampers 5 and 6. Further, the sample body 7 is irradiated with the electromagnetic wave emitted by the electromagnetic wave emission part 13 of an electromagnetic wave generator 9 before the sample body 7 reaches the copper block 3 by the falling of the plunger 1. Then the sample body is irradiated only while present between through holes 14a and 14b of a waveguide 4. Consequently, when the liquid that the sample contains is frozen, the area of amorphous solidification can be expanded greatly.

Inventor: ASANO YOJI
IPC: H02K37/22
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To miniaturize a selector valve and make it inexpensive. SOLUTION: As the flow in of the return oil in a spool chamber 46 through passage 85 to the inside space 84 of a stepping motor 69 is allowed, in order to obstruct the flow in of the oil to the inside space of a electric motor, an oil seal interposed between the output shaft and seal up ring is not required and consequently, the loss (consumption) of the generation torque of the electric motor by the friction resistance between the output shaft and oil seal is eliminated. Thus, the stepping motor 69 with a small capacity is sufficient.

Title: Detection method for uncut long material
Inventor: IITAKA TOSHIHIKO
IPC: B23Q17/20
Filed: 1989-12-27
Abstract: PURPOSE:To enable automatic detection of the uncut state of a long material by providing the detectors at the inlet and outlet sides of a cutting machine for detecting existence of the aforesaid long material at starting a cutting process. CONSTITUTION:When the leading end crop 1a and intermediate part of a steel pipe 1 are properly cut, the existence thereof is no longer detected with a detector 7. Also, when the trailing end crop 1b is properly cut, the steel pipe 1 is no longer detected with another detector 6. Consequently, if either of the detectors 6 and 7 senses the existence of the steel pipe 1 after a cutting process, the occurrence of an uncut condition can be identified. Upon recognition of the performance of a cutting operation on the basis of a signal from a cutting machine 2, a judgement part 8 monitors output signals from the detectors 6 and 7 for the predetermined time from the time of the recognition, and judges that an uncut condition occurs, if both the detectors 6 and 7 sense the existence of the steel pipe 1.
