IPC: B21K1/76
Filed: 1981-03-31
Abstract: PURPOSE:To obtain a forging device which is capable of finishing stably in a short time, by separating a mandrel from a horse form swage and rotating it at a high speed by energizing it upward when a press goes up, and setting the mandrel stably onto the horse form swage in case of pressing-down. CONSTITUTION:When a ring 23 is fitted into a mandrel 4 by a manipulator which is not shown in the figure, horse form swages 2, 3 approach each other along the guide formed on a table, and stop at the lower position of a press. Subsequently, when the mandrel 4 is rotated by operation of an oil pressure motor 5, the ring 23 is also rotated following said rotation. At the same time, said press operates, hits the upper part of the ring 23, and the hole is expanded. In this case, since the mandrel 4 is energized upward by a flat spring 19 through its supporting member 17, a gap is generated between the horse form swages 2, 3 when the press goes up, and it is smoothly rotated at a high speed.

Title: Thyristor
Inventor: OOHASHI HIROMICHI
IPC: H01L29/74
Filed: 1983-03-23
Abstract: PURPOSE:To obtain the titled device with built-in over voltage protecting ufnction which can trigger the voltage at a high di/dt dielectric strength against over voltage impression by a method wherein the minimum gate trigger current of a pilot trigger apart is set at 1/2 or less of the allowable breakdown current of a voltage breakdown region. CONSTITUTION:A P type base layer 20 having a curved part 19 is arranged in the inner periphery of the pilot thyristor PT. When an over current is impressed between the anode and cathode electrodes, an electric field concentrates on the curved part 19. At the time, the pilot thyristor PT and a main thyristor MT successively turn on by means of the breakdown current generated in the neighborhood of the curved part 19. In this case, the munimum trigger current IGT of said device PT is set at 1/2 or less of the maximum non destruction value IR (max) of a forward directional breakdown current by sufficiently increasing the gate sensitivity of said device PT first turning on. Thereby, the di/dt dielecric strength in voltage trigger can be largely improved.

Individual signals of the same phase are synthesized in the adder 22 and are sent to the discriminator. Thus, a signal having an amplitude three times as long as that of each detection signal is used for discrimination, and the S/N is improved, and this signal is desirable with respect to resolution. Phase matching is simplified by arranging coil sides in parallel.

Title: Detecting method for peripheral velocity
Inventor: OKADA YASUHIKO
IPC: G09F1/02
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which a precise peripheral velocity can be found by pasting a seal formed in such a way that it has a shape in which two quadrangles to be cut into pieces by removing a parallelogram from a rectangle are arranged in original positions in the rectangle and that inside parts of the two quadrangles have a color which is different from a ground color. SOLUTION: A parallelogram EFGH is removed from a rectangle ABCD. Inside parts of two quadrangles are formed in a color which is different from a ground color. A seal which is formed in this manner is pasted in such a way that its side AD and its side BC are directed to a direction at right angles to the circumferential direction of a roll. When the seal is pasted precisely, i.e., when a sensor is crossed with the seal in the position of a line L1, the ratio of the total time in which the sensor crosses two quadrangles to the time in which the sensor crosses the parallelogram sandwiched between the two quadrangles is equal to (the length of a segment MN + a segment PQ)/(the length of a segment NP)=R0 (a known value).  On the other hand, when the sensor is crossed with the seal in the route of a line L2, the ratio becomes (the length of a segment RS + a segment TU)/(the length of a segment ST) so as to become smaller than the known value R0 . When the time in which the sensor is passed through the segment ST is designated as T', a peripheral velocity can be corrected by an expression of T'×R1 (a measured time ratio)/R0 .

Title: Digital modulator
Inventor: NAGANO SATOSHI
IPC: H04L27/00
Filed: 1988-03-04
Abstract: PURPOSE:To reduce distortion due to the sampling noise of a modulating wave output in a digital modulator without using an analog filter by providing a means to cause the sample and hold time of a D/A converter output to be small to a sampling period. CONSTITUTION:A read only memory 2 stores the sample value of a modulating wave to correspond to an input data pattern which is an address in advance. However, for this sample value, the sample value is stored only at a sample point, where 1/natural number of 4 of a sampling frequency of a sine wave- shaped carrier goes to be maximum and minimum. Then, at the other sample point, '0' is stored. Accordingly, the contents of the memory 2 are read with a signal, which selects the input data pattern and sample point, as address information and successively converting the contents to an analog signal with a D/A converter 3, a signal to be shown with a real line in a figure (b) can be obtained. Further, since a ratio between the apparent sampling period and a sample and hold time goes to be small, the distortion due to a sampling noise 1 is reduced.
