Title: Apparatus for calibrating timing of test signal of semiconductor-testing apparatus
Inventor: NAGAI HIROYUKI
IPC: G01R31/30
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent a skew error of pins due to a temperature change inside an apparatus by obtaining a predetermined temperature correction coefficient and providing a memory means for storing the predetermined temperature correction coefficient and a control means for calibrating the timing of each pin. SOLUTION: The temperature inside a semiconductor test device is made to change. At this time, a minute change Δfsys of a frequency of a system loop and a minute change Δfdut of a frequency of a timing calibration loop for each pin are measured. Temperature correction coefficient K of each pin is obtained according to K=Δfdut /Δfsys , and obtained coefficient values are stores in a memory 40. The frequency of the system loop of the pin 1 as a reference pin and the frequency of the timing calibration loop are measured and set as references. The calibration value of each pin and the amount of a temperature difference correction when each pin is calibrated are obtained according to respective specific formulae. The changing amount of environmental temperature when each pin is calibrated can be corrected at the point of time for reference pin measurement with the temperature difference correction amount. Accordingly, a timing is adjusted with a factor of a skew error of pins being offset.

Title: Control system for stepping motor
Inventor: SAWADA KENJI
IPC: H02P8/24
Filed: 1982-12-24
Abstract: PURPOSE:To eliminate a control error caused due to a quick brake by forcibly coupling an acceleration table and a deceleration table at a jump control mode time. CONSTITUTION:A switching point data table 12 stores time information T6 instead of time information t6 of A step of an acceleration table 9 when advancing from the A step of the table 9 to the deceleration table 11. When becoming a jump control mode, the content of the table 9 is indexed up to (A-1) step, the content T6 of the table 12 is indexed at the A step, and is then entered to the index of the table 11. That is, a control error is eliminated by inserting buffer as time information T6 operating as a time information t5 buffer for providing the acceleration or time information 66' for providing deceleration instead of the form of applying a quick brake.

Title: Production of aliphatic triamine
Inventor: MIURA RYUICHI
IPC: C07C211/14
Filed: 1991-09-13
Abstract: PURPOSE:To provide an excellent process for producing an aliphatic triamine by the ammonia-elimination reaction of aliphatic diamine. CONSTITUTION:An aliphatic diamine expressed by general formula H2N-R-NH2 (R is 7-14C aliphatic group) is heated in the presence of a palladium oxide catalyst to effect the ammonia-elimination reaction. The formation of by-product can be suppressed and, accordingly, the selectivity of triamine can be increased by the use of palladium oxide catalyst. The complicate process and operation of conventional process become unnecessary. Since palladium oxide catalyst can repeatedly used, the production of aliphatic triamine can easily be performed by continuous reaction process.

Title: Speed controller of motor
Inventor: OGINO TADAAKI
IPC: H02P7/295
Filed: 1983-12-13
Abstract: PURPOSE:To smoothly rotate a DC motor at a low speed operation time by dropping a voltage applied to the motor when the motor is operated at a low speed operation time to lengthen the conduction time of a thyristor. CONSTITUTION:If a speed control signal applied to a control unit 14 is the prescribed speed V or higher, a switch 22 is closed, switches 21, 23 are opened to control the rotating speed. If the signal is less than the prescribed speed V, the unit 14 opens the switch 22 and closes the switches 21, 23 to control the rotating speed. Then, the peak value of the AC current applied to a thyristor 12 decreases, and the conducting phase is advanced. Accordingly, a pulsating current of long conduction time is generated. Thus, the rotating irregularity of a motor 1 can be prevented to improve the positioning accuracy of a tool.

Title: Disc cartridge
Inventor: MASUI HIROYUKI
IPC: G11B23/033
Filed: 1984-11-10
Abstract: PURPOSE:To obtain a secure adhesion of the liner and external case, by making peripheral part of the unwoven fabric liner and adhesive pat of the external case radial and same size and adhering them by ultrasonic wave welding. CONSTITUTION:The welding pattern Q of a liner 3 and an external case 4 is so designed that welding is done almost radially towards the peripheral parts and many joining parts of same axis length form a joining part (b), and the density of joining part (b) of outside angle A of a notch 3b is higher than joining parts (b). When fusion welding or ultrasonic wave welding is applied, the deposition density of the outside corner A of the notch 3b is increased and becomes stronger than other joining parts (b), and further the deposition strength is also increased. Therefore the occurrence of peeling off of the liner 3 caused by the rotation of a disc 1 can be prevented. Since the axis length of each joining part is designed to be the same length, there is no protrusion of the liner 3 when the disc 1 rotates, failures such as deformation of the liner 3 due to the concentration of stress at and peeling off at the protrusive part are solved, and the causes to give an adverse effects to recording/reproducing the disc 1 are reduced.
