Title: Method for cutting tube stock for cold working
Inventor: TAKIMOTO GIICHI
IPC: B21B21/00
Filed: 1993-03-30
Abstract: PURPOSE:To improve the yield by restraining the generation of surplus part and to improve working efficiency by reducing the number of divisions. CONSTITUTION:The longest stock is extracted from tube stocks of raw materials. The length of the longest stock is equivatent to an integral multiple of the length of product tube and is the nearest length to the max. length of the tube stock which is placeable on the inlet table of a working machine. When a short stock shorter than the longest stock is produced and its length is larger than the length of the min. tube stock which is placeable on the inlet table, the short stock is extracted as it is. When the length of the short stock is smaller than the length of the min. tube stock, any short stock is made so as to be larger than the length of the min. tube stock by increasing the number of the short stock.

Title: Tilt signal generating circuit
Inventor: KUSANO SATOSHI
IPC: H04N5/95
Filed: 1981-06-25
Abstract: PURPOSE:To realize the reliability as well as a simple and compact structure for a tilt signal generating circuit, by controlling the charge/discharge of a constant current to a capacitor only through a logical circuit. CONSTITUTION:When the sample holding pulse S/H is set at a low level, a switch SW1 is turned on via an AND gate 3. At the same time, a switch SW2 is also turned on with a low level output of an NAND gate 8 via an inverter 7, etc. to which the RS type FF reference signals produced from the NAND gates 5 and 6 which work in response to a high level output of a level comparator 4 is applied. Then the switch SW2 is turned off by the comparator 4 and the RS type FF when a capacitor C discharges a constant current to reach a prescribed level of voltage. Thus the capacitor C receives the charge of a constant current to produce a tilt signal, and the level is clamped via a transistor Q1 when the capacitor C reaches a prescribed level of voltage. In such way, the charge/discharge of the constant current is controlled only by a logical circuit with no use of a monostable multivibrator which is unstable to the temperature, etc. Thus the reliability and a simple and compact structure are attained for a tilt signal generating circuit.

Abstract: PROBLEM TO BE SOLVED: To control rotation of an attitude angle by reading from a memory a correction amount at the time immediately before an attitude angle beyond a limit range is corrected to a limit angle to obtain a braking amount, and braking the speed of an object at a brake timing according to the braking amount. SOLUTION: An attitude angle of an artificial satellite is detected with an attitude angle sensor 101. The detected attitude angle is inputted to a notification section 21 of a determination section 24. The notification section 21 compares the attitude angle with a target angle and, when they are in agreement, notifies a braking timing to a braking section 23. When the attitude angle detected with the determination section 24 is beyond a limit range, a start of correction is directed to a correction section 25. A correction amount immediately before performing the correction with the correction section 25 is stored in a memory from which the correction amount is read to obtain a braking amount. According to the braking amount and at a braking timing of the braking section 23, speed of an object is braked. Thus, rotation of the attitude angle may be braked.
