Title: Leveling control method for thick plate rolling
Inventor: ISHIHARA YOSHIAKI
IPC: B21B37/00
Filed: 1986-09-18
Abstract: PURPOSE:To surely prevent meandering and cambers of a rolled stock by controlling a profile difference between the driving side and the operating side ends in a rolled stock contact range of the succeeding pass calculated based on a profile value sequentially corrected between passes. CONSTITUTION:A thickness distribution in the thickness direction is calculated based on a roll profile value, etc. in the range in which a rolled stock 3 comes in contact with upper and lower rolls 1 and 2; on the other hand, a thickness detector 8 finds an actual plate profile. Then, a roll profile value is corrected by a roll profile learning device 9 based on a calculated plate profile and the actual plate profile. The learning device 9 calculates the sum of upper and lower profiles of the driving side end and of the operating side end of the upper and lower rolls 1, 2 at the succeeding pass based on the corrected roll profile value and sends the sum to a profile difference arithmetic unit 10 to calculate a difference between both end profile differences. The difference is sent to a leveling controller 11 to control the thickness profile difference of both ends to be zero by performing one or more of a roll gap adjustment, adjustment of a bender force of the operating and the driving side, and adjustment of a shift position complying with a plate profile difference.

Filed: 1987-08-31
Abstract: PURPOSE:To revise the response speed of an inverse amplifier even after the circuit layout is finished by providing a speed control MOS transistor(TR) of the same polarity as that of a P-channel MOS TR or an N-channel MOS TR so as to vary the gate potential. CONSTITUTION:The drain of a speed control MOS TR 1 is connected to the source of a P-channel MOS TR 2, the source is connected to a power potential VDD and the gate is connected to receive a control signal CONT respectively. In bringing the control signal CONT to the potential V1, the leading time of the output depends on the channel resistor of the speed control MOS TR 1 and the P-channel MOS TR 2. The potential of the control signal CONT is varied in this way to change the channel resistor of the speed control MOS TR 1 thereby varying the speed between the input and output.

Title: Method of sealing package
Inventor: SHIOZAWA KOJI
IPC: B23K26/00
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To facilitate sealing with a laser beam which is of intensity proper for safety operation by precoating the surface of a plate-shaped material requiring a seal thereon with a resin coating, and thereafter putting the seal using a laser beam, and to improve the visibility of sealed characters by making the characters indelible. SOLUTION: A surface of a mirror-polished plate-shaped material 1 requiring a seal thereon is precoated with a resin coating 5. Then, the seal is put by a laser beam. As a result, the coating 5 can be carved easily, and since its color changes greatly, the operability is improved, making sealed characters easy to read. Furthermore, the characters for indication sealed by the laser beam become indelible by a solvent, etc., and, due to the presence of the coating 5, the laser beam used may need not necessarily be so intense, thus putting a relatively weak laser beam to use for full sealing operation. At the same time, hazards associated with the operation is almost eliminated.
