Title: Multirotary absolute encoder
Inventor: MORITA TORU
IPC: G01D5/16
Filed: 1994-07-18
Abstract: PURPOSE:To detect an absolute position of a code plate by outputting a rotating speed signal corresponding to a rotating speed of the code plate, selecting a first or a second rotation data in accordance with the signal, thereby eliminating an internal latch time lag between data of a multirotating amount and data of an absolute address in one rotation. CONSTITUTION:A data signal (c) of an absolute value in one rotation which is output from an optical encoder part 5 is loaded at a lower digit of an up- down counter circuit 6, and a data F of a multirotating amount from a multirotating amount-series circuit block 1 is loaded at an upper digit of the circuit 6. Counting is executed up or down from the lowest bit when incremental two phase signals (d) and (e) in one rotation output, from the encoder part 5 are received. A data H of an absolute address in one rotation and a data G of a multirotating amount are transmitted from a lower output of the counter circuit 6 and an upper output of the counter circuit 6, respectively. The data G is updated by the two phase signal of the encoder part 5. Therefore, no lag is generated between the address data H and the rotating amount data G irrespective of a change of a rotating speed.

IPC: B22D41/02
Filed: 1982-10-26
Abstract: PURPOSE:To prevent the intrusion of Zr into molten steel for a non-directional electrical steel plate and to reduce the iron loss of the electrical steel plate of product by coating a specific refractory material on the surface of the ZrO2 brick used in the slag zone in a ladle to be used for treating the molten steel. CONSTITUTION:A zirconia brick having high refractoriness is used in the zone of the molten slag in a ladle for treating molten steel for a non-directional electrical steel plate contg. <4% Si. The brick is further coated thereon with a magnesium-chromium (MgO-Cr2O3) refractory material or MgO refractories. The entry of Zr into the molten steel from the zirconia brick is prevented and the formation and deposition of ZrN in the molten steel is prevented. The increase in iron loss as an electrical steel sheet on account of a retardation in the grain growth of a recrystal by ZrN in the stage of finish annealing is prevented when the molten steel is cold-rolled to the electrical steel sheet.

Title: Apparatus for detecting defective pattern
Inventor: SUDA TADASHI
IPC: G01N21/956
Filed: 1984-09-10
Abstract: PURPOSE:To assure the correct selection of defectively processed patterns, by providing an abnormal direction detecting means comprising a photodetecting system having a large light-receiving surface and a defect judging means for judging if an abnormal direction signal indicates a real defect or not based on a signal from a normal pattern detection means. CONSTITUTION:IF the sum of four signals of abnormal directions is larger than a threshold value equivalent to the signal level relating to the rounding of corners, such pattern is always determined as defective. If the sum is equivalent to the threshold value the second signal eab from the top is selected from the four abnormal direction signals by a first signal selection circuit 47. Among four normal signals, the second signal e' from the bottom is selected by a second signal selection circuit 49. This signal e' is multiplied by (1+alpha) to obtain eno. The signals eab and eno are compared by a value comparing circuit 50. If eab> eno, the pattern is determined as defective. A pulse detected by a pulse detection circuit 46 is allowed to pass through the logic judging circuit 51 and to become a defect signal only when it is judged defective by the adding circuit 48 or the value comparing circuit 50.

Abstract: PURPOSE:To improve energy efficiency by positioning a hydraulic turbine in an expansion process of reverse Rankine cycle, positioning a booster pump in a pressure-rise process of Rankine cycle, and driving the booster pump by the output of the hydraulic turbine. CONSTITUTION:As for devices arranged in reverse Rankine cycle, a hydraulic turbine 4' connected to a booster pump 6' is positioned instead of an expansion valve in an expansion process 3'-4', hereby, an isoenthalpic expansion process between the expansion process 3'-4' is converted to an isoentropic expansion process. Consequently, the hydraulic turbine 4' can give mechanical energy to the outside, and pressure-up work of the booster pump 6 provided in a pressure-up process B-C of Rankine cycle is compensated in fact. In this case, input mechanical energy from the outside is only an input mechanical energy E to a gas compressor 3' in a compression process of the reverse Rankine cycle. Thus, energy efficiency is remarkably improved, compared with the customary one.

Synchronizing-radiowave transmitting antennas 1 and 2, which are provided at a master station that is one of the fixed stations, transmit position measuring radiowaves to slave stations (1) and (2) as synchronizing radiowaves. Synchronizing means 4a, 4b, 6a and 6b, which are provided at the slave stations (1) and (2) receive the synchronizing signals and transmit the position measuring signals having the same phase. Thus, mobile stations (b) receive the transmitted radiowaves and measure the difference in arriving times of the radiowaves. The position of each mobile station can be obtained based on the intersection of hyperbolic lines, whose foci are the two fixed stations.

Title: Television receiver
Inventor: HIRASAWA KAZUO
IPC: H04N5/45
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To naturally display character signals and video signals on the same screen by dividing the screen of an aspect ratio 16:9 into two areas, displaying the character signals in one of the areas and displaying the prescribed video signals in the other. SOLUTION: The video signals whose aspect ratio is 16:9 are converted to the video signals whose aspect ratio is about 10:9 by non-uniform compression and aspect conversion. Thereafter, by performing changeover with the character signals in a horizontal scanning cycle in a switching circuit, prescribed screen constitution is attained. In this case, since the compression ratio of the video signals is made small in the center part of the screen and made large in the left and right peripheral parts of the screen in a non-uniform compression and aspect conversion circuit, video images for which expansion in a vertical direction at the center part of the screen is reduced are realized.  At the time, when the screen of the aspect ratio 16:9 is divided into the two areas, the character signals are displayed in one of the areas and the non-uniformly compressed and aspect converted video signals are displayed in the other area, the distortion of the video images becomes inconspicuous and quality is improved.

Abstract: PURPOSE:To make it possible to control accurately a tube current to the arithmetically obtained tube current from the actual measured values of a current flowing through a smoothing condenser, a current flowing through a tube voltage detector resistance and the output current of a rectifier circuit. CONSTITUTION:When energized, a current I1 flows through a resistance 7, a current I2 through a resistance 31, and a current I3 through a resistance 18; therefore, a voltage obtained by multiplying each resistance value by each current value appears across the resistance 7, 31, and 18 respectively.

After adjusting the signals a to c with variable resistances 57, 59, 61 so that a tube current Ix will be similar to the output d of an arithmetic amplifier 54, the output d of the arithmetic amplifier 45 is inputted to a filament heating circuit 9. In the filament heating circuit 9, the preset tube current signal and the output d of the arithmetic amplifier 54 are compared, and the heating power for the X-ray tube 5 is adjusted so that the difference between them will be zero.
