Title: Chattering detection method in cold rolling
Inventor: SAIDA SEISHIRO
IPC: B21B33/00
Filed: 1994-07-13
Abstract: PURPOSE:To detect even a light chattering in cold rolling of a thin-plate strip on-line and with a high sensitivity by providing a two-stage roll for holding a rolled material closer to a mill cutting tool and measuring the vibration of the two-stage roll. CONSTITUTION:A two-stage roll 5 is provided close to a mill cutting tool 4 of a rolling machine and the vibration is measured for detecting chattering. A pressure is applied to the roll 5 to the extent so that a rolled material S and a roll do not slip and the rolled material S does not deform. When chattering occurs when performing cold rolling to a rolling machine 1, an abnormal vibration is propagated to the roll 5 via the rolled material S and chattering can be detected by measuring the vibration of the roll 5. It is desirable that the vibration of the roll 5 should be measured by providing a vibration sensor 6 at a roll check 8. When performing measurement, a signal from the sensor 6 is inputted to a vibration analyzer 7 for analyzing for example vibration speed or vibration acceleration by the order ratio analysis method.

Title: System for recording/reproducing signal in magnetic tape in cassette
Inventor: NORUBERUTO KURISUCHIYAN FUORUM
IPC: G11B15/675
Filed: 1990-06-19
Abstract: PURPOSE: To always position the magnetic tape at the same level even in a deviated device by possessing one deviated positioning pin capable of engaging itself with a deviated positioning hole with a gap in some measure. CONSTITUTION: The new positioning pin 21 has a conical part 53 extending from a free end surface 51, and four recessed parts 55 are extended along a circumferential surface of this conical part 53. This new cassette 3 has two star-shaped positioning holes 35A and 35B to be engaged with the two new positioning pins, and the new positioning hole 35B has a large gap than the positioning hole 35A to some extent in order to allow an error of a distance between these holes. In other words, the new positioning holes 35A and 35B have both the same dimension (x), but a dimension y1 in a lateral cutting direction of the positioning hole 35A is smaller than a dimension y2 of the positioning hole 35B. Consequently, even when an initial position of an end part 51 of the new positioning pin 21 is slightly incorrect, the pin is easily engaged with the star-shaped new positioning hole 35A.  Thus, it is guranteed that the magnetic tape is correctly positioned in the deviated device.

Title: Airflow equalizing unit in air conditioning
Inventor: FUKUSHI YUTAKA
IPC: F24F13/02
Filed: 1980-11-15
Abstract: PURPOSE: To dispense with a special type spring as well as to simplify the constitution of an air conditioning unit by installing more than one screens among each of which springs are inserted.  
     CONSTITUTION: Since in a low pressure range the deformation of a spring 7 is larger than that of a spring 9, amounts of movement of screens 6 and 8 to a shaft  2 are different, which varies the opening area of a ventilation flue 11. As the air pressure increases, the difference in the deformation of springs 7 and 9 increases, and a screen 8 for the low pressure contacts a screen 6 for the medium and high pressure, completely closing the ventilation flue 11. At this time, ventilation is allowed through a ventilation flue 12 located between a scrren 6 and a partition member 10. As the air pressure is increased further, both screens 6 and 8 move as one body, pressing the spring 7 only. Accordingly, only the ventilation flue 12 varies its opening area depending upon the air pressure.
