Title: Needle stoppage controller in sewing machine
Inventor: MATSUZAWA KIYOSHI
IPC: G05D3/12
Filed: 1992-05-22
Abstract: PURPOSE:To always stop a sewing machine in a prescribed short time so as to locate a needle at a lower position after a stopping signal is outputted by a push-button switch, etc. CONSTITUTION:This sewing machine is the one to perform braking needle stoppage by the stopping signal S3 from the push-button switch, etc., setting a pulse control type motor 1 as a driving source. Needle stoppage control driving is performed by always inputting a main spindle signal S1 and a motor pulse signal S2 to a microcomputer 3, and inputting the stopping signal S3. The number of motor pulse signals S2 until the next main spindle signal S1 is outputted after the machine is operated at prescribed slow speed and is computed by the microcomputer, and after the motor is driven by the number of pulses when the stopping signal S3 is inputted, the slowdown of the motor 1 is started.

Title: Pendulum balancer mechanism for spherical polisher
Inventor: OGUE ICHIROU
IPC: B24B13/00
Filed: 1983-07-20
Abstract: PURPOSE:To reduce load due to a tilt angle of a pendulum as well as to make tilting drive attainable in an optional manner, by constituting an auxiliary thrust in a pushing cylinder fitted with a brake mechanism in the optional tilt angle of the pendulum so as to be optionally settable. CONSTITUTION:In case of a pendulum balancer mechanism for a spherical polisher suitable to an auxiliary pushing thrust mechanism for auxiliary use of a pendulum subjecting a heavy load, the pendulum 1 is required to be titled to a specified polishing position where a work 2 being locked onto a rotary table 6 is mounted thereon. Next, when a tilt angle of the pendulum 1 is small, a thrust is as well small whereby the pendulum is tilted with a driving motor 7. When the tilt angle is larger enough, a pushing cylinder 9 detects a limit switch 10 through a dog 11 at the other end of the pendulum 1 and feeds the pushing thrust by means of setting pressure in an air regulator and a solenoid valve. Thus, load due to the tilt angle of the pendulum is reduced and tilting drive is smoothly carried out.

Title: Reverse drawing die device
Inventor: KOBAYASHI HIDEKAZU
IPC: B21D22/24
Filed: 1979-10-11
Abstract: PURPOSE: To press the work of a convex curved surface to a die and reverse drawing the same in one process by means of a punch, by providing a punch ring to the circumference on the punch side at the time of reverse drawing said work.  
     CONSTITUTION: First, a punch holder 17 is moved upward to detach an insert pad 28 and a punch ring 29 from a die 4. Next, the work W is placed on knock-out pins 13, 14 in such a way that its convex curved face side opposes to a punch 20. Thence, when the punch holder 17 is lowered, the insert pad 28 and punch ring 29 contact the convex curved face side of the work W and position the same. When it is lowered further, a spank rod 22 presses the rod 7 which in turn lowers a cushion pad 6, causing the knock-out pins 13, 14 to descend from the surface of the die 4. Following to which, a spring 26 springs a pad base 25 downward and the insert pad 28 grasps the work W between the same and the die 4. Thence, the punch ring 29 deforms the work W to the surface shape of the die 4 by the elastic force of a spring 33; at the same time, the work W is pulled downward by the descending of a punch 20, whereby drawing is accomplished.

IPC: G11B5/31
Filed: 1983-07-19
Abstract: PURPOSE:To improve the accuracy of processing size and to attain the simultaneous processing for plural magnetic heads by forming a conductor pattern on a substrate containing plural magnetic heads to be processed. CONSTITUTION:When magnetic heads 5a-5n are processed, the connection is measured between terminals 7a and 7b as well as 7c and 7d of conductor patterns 6a and 6b provided at both ends of a substrate 4.

In such a way, the accurate throat height is obtained for plural magnetic heads. Thus it is possible to process simultaneously and accurately plural magnetic heads compared with the processing using the optical measurement. This also reduces the working time.
