Title: Method of changing over pwm pulse
Inventor: HASHII MAKOTO
IPC: H02M7/48
Filed: 1990-05-21
Abstract: PURPOSE:To decrease the change of a current and prevent the shock in change over by shifting it from asynchronous modulation to synchronous modulation when any point of 0 deg., 120 deg., 240 deg. of a signal wave has entered the region of 270 - 360 deg. of the carrier in asynchronous modulation. CONSTITUTION:The output of a circuit 15 is input into a latch circuit 16 so as to add itself to one of shifting conditions. Hereby, when any of the timing signals, which show 0 deg., 120 deg., and 240 deg., of a signal wave has entered the region of 270 - 360 deg. of an asynchronous carrier after a shifting command is issued from a frequency judging circuit 7, the switch 6 changes over from the output of a comparator 5 to the output of a comparator 4 by the output of a latch circuit 16.

Filed: 1983-07-18
Abstract: PURPOSE:To provide the proper forward protecting number of stages to each of many lines having different error rate by changing the forward protecting number of stages by the information from an error rate detecting circuit. CONSTITUTION:A synchronism pattern coincidence/dissidence detecting circuit 1 detects the coincidence between a frame synchronizing pattern in a reception signal and a frame synchronizing pattern formed at a reception side and a coincidence pulse 8 is counted by a backward protecting and counting circuit 5 by the number of backward protecting stages to attain the synchronism state.

Title: Stress measuring device by x-rays
Inventor: SAKAI TOSHIHIKO
IPC: G01L1/00
Filed: 1982-07-27
Abstract: PURPOSE:To measure easily stress with high accuracy, by including a means for making X-rays to parallel ray fluxes disposed in front of an irradiation means, and a slit disposed in the optical path of the diffracted X-rays in front of a detection means and detecting simultaneously the photodetection position of the diffracted X-rays and photodetection intensity. CONSTITUTION:The X-rays come out of an X-ray radiator 1 are made into parallel luminous fluxes with a solar unit 6, are diffracted and reflected by a material 3 to be measured and is detected with a PSD51 through a slit. The figure shows the photodetection position at the axis of abscissa and the photodetection intensity at the axis of ordinate, and the diffraction angle is determined from the central point A of the intensity distribution. A peak of the intensity is generated in the position 7 on the PSD51 if the position of the material surface is 31. Even if the surface position deviates to 32, the peak of the intensity is generated in the diffracted beam in the same position 7 as incident beams 61 and 62 are parallel. In other words, even if the surface position changes, the position of the intensity peak on the PSD remains without changed. There is thus no need for moving the detector PSD on the photodetection side. The error in controlling the position of the surface to be measured is not a factor for stress measurement.

Title: Dehydrating method for freeze-thawed sludge
Inventor: YOSHIDA MASATAKA
IPC: C02F11/20
Filed: 1979-10-11
Abstract: PURPOSE: To make efficient dehydration possible, by using a variable speed pump for charging freeze-thawed sludge, and by controlling the operation of the motor in accordance with the pressure in a charging pipe which depends upon the accumulated sludge in a sludge chamber.  
     CONSTITUTION: Freeze sludge is charged from a reservoir 62 to a sludge chamber 32 by the operation of a pump 66 for charging sludge. At the start of sludge charge, no sludge is in the sludge chamber 32, the discharging pressure (P 0 ) of the pump 66 is in the low state, hence the number of revolution of the pump 66 is kept at constant, so that a large quantity of sludge is discharged and deposited solid matter is separated from liquid smoothly. When the sludge is accumulated slowly in the sludge chamber 32, the discharge pressure of the pump is increased to the filtration finish pressure P 1 . The discharge pressure is detected by a pressure detector 72, and the signal is fed through a transducer 74 to a variable speed motor 70. The number of revolution of the pump 66 is reduced so as to keep the discharge pressure to the compression pressure, hereby the sludge is dehydrated by compression. When the sludge is formed into cake, the discharge pressure exceeds the compression finish pressure P 2  arriving at a pressure at which the cycle is to be stopped. At that time, the charge of the sludge is stopped to be removed from the sludge chamber 32.
