Patent JP-S6078316-A (JP)
Title: Position detector
Inventor: OKUYA NORIO
IPC: G01D5/36
Filed: 1983-10-05
Abstract: PURPOSE:To detect a position with a high resolution in a small-sized constitution by generating moire stripes on a slit plate of a detector and detecting the position of moire stripes in a photoelectric incremental position detecting device. CONSTITUTION:Moire stripes generated by a fixed slit plate 6 and a rotary slit disc 7 are projected onto light receiving faces of position detectors 8 and 9 by a light source 5 and a cylindrical lens 10. Positions of bright parts of moire stripes projected to light receiving faces are outputted as electrical signals to a selecting circuit 11. The selecting circuit 11 selects the output of the detector 8 or 9 and outputs it as a position signal. The position of moire stripes on light receiving faces is detected in this manner to detect the position of the rotary slit disc 7. Thus, the position is detected with a high resolution without enlarging the rotary slit disc by the small-sized constitution.

Inventor: KANG SANG-UG
IPC: G06F9/32
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To provide an execution control circuit for a repetitive syntax in a digital signal processing chip. SOLUTION: This circuit includes the least significant bit state detecting part 70 which detects a state of each bit of a counter register to which the execution count of a repetitive syntax is loaded and outputs a valid signal on a prescribed level in accordance with the state of the least significant bit and each state of 1st and 2nd signals when all of bits except the least significant bit become zero, a conditional clock outputting part 72 which inputs a clock signal and the 1st and 2nd signals and outputs the clock signal only when the 1st and 2nd signals are valid and an end condition signal outputting part 60 which outputs an output signal of the least significant bit state detecting part when a signal outputted from the conditional clock outputting part is valid.  Thus, it is possible to prevent an error when the execution count of the repetitive syntax is zero, to reduce execution time and also to suppress wasteful usage of program memory at the time of embodying the entire algorithms.

Title: Operating method for sintering furnace
Inventor: HASEGAWA YUTAKA
IPC: F27B17/00
Filed: 1986-08-08
Abstract: PURPOSE:To uniformize the temp. distribution in an inner case by disposing heating sources to the upper and lower parts of the inner case, heating the inner case uniformly from the upper and lower parts at the time of a vacuum state and increasing the output of the lower heating source at the time of a high pressure state. CONSTITUTION:The upper and lower heating sources 5A, 5B are disposed in the space between the inner case 4 and heat insulating material 2 provided in a furnace vessel 1 and are separately controlled by a control circuit 6. The two heating sources 5A, 5B are operated with approximately the same outputs to radiate the radiation heat uniformly from the wall surface and to heat the entire part uniformly in the inner case 4 in the case of evacuating the inside of the inner case 4 to a vacuum. The output of the upper heating source 5A is dropped and the output of the lower heating source 5B is increased to heat the lower part of the inner case 4 concentrically when the high pressure state is attained. The convection of the gaseous pressure in the inside and the large radiation heat from the lower part are thereby balanced and the temp. distribution as a whole is uniformized.

Abstract: PURPOSE:To make it possible to evaluate the low-temperature flowability of heavy oil in a short time by adjusting a cooling rate so as to obtain a result that the temperature of filtration limit by deposition wax in a testing apparatus corresponds virtually to the temperature of working limit in a practical installation. CONSTITUTION:A sample is made to flow out from the lower sides of vessels 1 to 4 to a suction bottle 27 kept at a reduced pressure lower than the atmospheric pressure, through fuel strainers 11 to 14, and a flow rate is measured from the time required from the start of suction to the passing of the oil level of the sample in a prescribed quantity through level sensors 23 to 26. At this time, cooling of the heavy oil in the vessels 1 to 4, the strainers 11 to 14 and a piping is started from a temperature being higher than a cloud point by at least 3 deg.C or above or by 5 deg.C or above preferably, at a cooling rate of 2 to 20 deg.C per hour. At a time point when the temperature higher by l to 2 deg.C than the one for practical use is reached, the lowest temperature of those at which the flow rate of the heavy oil made to flow out through the strainers 11 to 14 is substantially the same as that at normal temperatures is made a criterion for determination of low-temperature flowability.

Title: Information signal reproducer
Inventor: TAKAMO HIDEKATSU
IPC: G11B21/10
Filed: 1984-09-06
Abstract: PURPOSE:To stabilize the tracking performance by changing the gain of a tracking control loop in a drop-out detection mode and therefore preventing a tracking error which is caused by the drop-out, etc. CONSTITUTION:The record of a disk 1 is read out by a fly lead 13 and a signal detecting circuit 15. When a drop-out is detected by a drop-out detecting circuit 23, an analog switch 17 of a tracking control loop is switched by the detection output of the circuit 23. Then the gain of the tracking control loop is changed or this control loop is cut. Thus the tracking control loop has no reply to the shrinkage-shaped noise signal obtained when the drop-out is produced. This prevent the generation of a tracking error and stabilizes the tracking performance.

Title: Varying device of output pulse number
Inventor: HARA KENJI
IPC: H02P29/00
Filed: 1983-10-05
Abstract: PURPOSE:To improve the flexibility of a device by varying optionally the number of two-phase pulses (PPR), which are outputted from a pulse oscillator (PG), per one rotation in a range smaller than the number of slits of the PG. CONSTITUTION:A pulse processing circuit part 1 converts the two-phase pulse outputs Ai and Bi of the PG to binary data SIGMA1 and SIGMA0, to obtain (0, 1) for the forward rotation of the PG and (1, 1) for backward rotation and (0, 0) for stop. A PPR setting part 4 can set freely a number <=1,023. An integrating circuit part 2 adds or subtracts a value, which is set by the setting part 4, to or from the preceding value held in a DFF2-d in accordance with the timing of the output of the processing circuit part 1. An overflow generated in B1-B10 by addition or subtraction appears in BX-1 and BX. A two-phase converting circuit part 3 converts the binary data BX-1 and BX to two-phase outputs. Thus, the number of the two-phase pulses is varied to an optional number to improve the flexibility of the device.
