Title: Reproducing circuit for magnetic storage device
Inventor: SUGINO SO
IPC: G11B5/09
Filed: 1985-12-18
Abstract: PURPOSE:To remarkably improve the stability with no adjustment by employing a digital circuit for at least either a peak detection circuit or a demodulation circuit. CONSTITUTION:The digital peak detection circuit uses an A/D converter provided at the pre-stage, which converts an analog signal into a digital signal to receive a read signal, and a zero cross detection circuit uses a code memory 65 and a code comparator 66 so as to receive a digital read signal DRS' at the same time and to compare the code of the received signal with the code of the received signal before one sample period sequentially thereby outputting a read data pulse RDP. The read data pulse RDP is fed to a digital demodulation circuit 70, from which a pulse interval measuring data is fed to a quantized circuit. Then the signal is quentized based on a prescribed threshold value corresponding to a predetermined section as to the said pulse interval.

Title: Power converter
Inventor: GEKITO MASAKAZU
IPC: H02M7/48
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a power converter which hardly causes a switching loss and, accordingly, does not generate much heat. SOLUTION: The electric current flowing to a semiconductor switching element 21 suppresses the voltage rising rates of semiconductor switching elements 21 and 22, because the current shifts to a snubber capacitor 51 to gradually charge the capacitor 51 and discharge another snubber capacitor 52. No turning-on loss occurs in the switching element 21, because a diode 22a is conducted by the energy stored in a smoothing reactor 31 during a period, after the voltage at the switching element 22 becomes zero, and, while the diode 22a is conducted, the switching element 22 is turned on.

IPC: B21J13/03
Filed: 1986-11-28
Abstract: PURPOSE: To make it possible to prepare for mounting dies on the outside of the machine and to shorten the downtime of the machine necessary for die change by arranging male dies and female dies at a change magazine of die blocks. CONSTITUTION: At the time of changing the die blocks, a centering element 11a by a pressure medium remains in addition to clamping elements 6a, 6b in the clamping portion on a machine body 25 side or pressurizing slip part 22 side. This centering element 11a is driven from a central control panel. The clamping and fixing of the die blocks 5a, 5b by the clamping elements 6a, 6b is effected by fitting of the piston head 32b of the centering element into a centering groove 26b meeting the same. In addition, this clamping and fixing are so controlled with a controller by the pressure medium that the overall correct position setting of the die blocks may be automatically achieved during the clamping work of the die blocks at each time thereof.  Then, the exactness of the centering and the adjustment is capable of eliminating the work for separately adjusting the male die 1 and the female die 13 in horizontal and perpendicular directions.

Abstract: PURPOSE: To improve the directivity for the dropping point of a golf ball by making the centerline of the horizontal bulge of a club head parallel to the centerline of the club shaft, and making the centerline of a vertical roll perpendicular to the centerline of the club shaft. CONSTITUTION: Rotation of a club head 1 due to the position of each striking point on a face, as measured with a three-axis distortion gauge attached to a club shaft 4, is caused about the sweet spot 0 of the face 2 and either perpendicular or parallel to the shaft axis P-P of the club shaft 4. The face 2 of the club head 1 is therefore molded into a horizontal bulge having a fixed radius of curvature and into a vertical roll, so that when a golf ball is struck at a position off the sweet spot 0 of the face 2, a force (gear effect) that tends to rotate the golf ball in the direction opposite to that of rotation of the club head 1 works, improving the directivity for the dropping point of the ball.
