Patent JP-S60164965-A (JP)
Title: Information reproducing device
Inventor: TANAKA SHINICHI
IPC: G11B20/10
Filed: 1984-02-07
Abstract: PURPOSE:To read accurately and stably information even from a reproduction signal being changed in duty ratio by making digitally control of duty ratio. CONSTITUTION:Deviation of duty ratio can be detected by generating a clock sufficiently shorter than the element waveform of a recorded digital signal in period by a clock generator 11 and counting the clock by the first counting device 12. When the first counting device 12 generates an output pulse, the second counting device 13 makes regular counting or backward counting and counted value changes. A closed loop is constituted to apply D/A conversion to the counted value by a D/A converting device 14 to feedback to threshold value of a waveform shaping device 10. When the maximum value is attained, the second counting device 13 stops regular counting, and when the minimum value is attained, stops backward counting. Thus, stable control is made even when the duty ratio of a reproduction signal deviates remarkably.

Title: Variable wavelength optical filter and sensor system
Inventor: KENTO DEI BUINSENTO
IPC: G01J3/12
Filed: 1991-02-14
Abstract: PURPOSE: To read out respective wavelength components by optical sensors by receiving an optical beam consisting of plural wavelength components, decomposing the received beams into respective components and individually projecting the components. CONSTITUTION: One plane of a Fabry-Perot etalon is deviated from a parallel state so as to be slightly inclined and an one-dimensional optical sensor array is arranged along the inclination. An etalon array obtained by combining the parallel Fabry-Perot etalon and an optical wedge or step-wisely increasing or reducing a face interval may be used instead of the inclined Fabry-Perot etalon. When an optical beam 25 is made incident upon the inclined Fabry-Perot etalon, the wavelength of transmitted light or reflected light is changed along the inclination because the face interval is changed in accordance with an incident position, and the wavelength of an outgoing optical beam is also increased to the increasing direction of the face interval.  Since incident light is projected from a different position along the inclined direction of the etalon in each wavelength component, each wavelength can be read out by the one-dimensional optical sensor array. Other constitution is also the same in principle.

Title: Multi-bit subtractor with limiter
Inventor: HASHIMOTO MASAHIRO
IPC: G06F7/38
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a multi-bit subtractor with a limiter, which is constituted by a small scale to shorten a processing time without requiring the subtractor with bit width being the same as that for calculation. SOLUTION: In the multi-bit subtractor with the limiter, the high-order bits of a number to be subtracted (A) and a subtracting number (B) being two input values for executing subtraction are compared by a comparator 105, selecter signals ENB MAX or ENB MIN for adopting the fixing values of the upper limit value MAX and a lower limit value MIN of the limiter as a subtaction result when the difference is more than two are outputted to a selecter 9 and the selecter signals SEL1 and SEL2 for adding '0' or '1' to the high order of the low-order bit of the larger number within the number to be subtracted (A) and the subtracting number (B) when the difference is one are outputted to bit adding selecters 106 and 107.  The subtractor 108 executes the subtraction of the low-order bit and the selecter 109 selects which one of the subtraction results of the fixing value or the subtractor 108 is used so as to output it.

Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide an input torque inference device which can carry out an accurate and stable inference of the input torque of an automatic transmission for a long period in every vehicle. SOLUTION: A first input torque inference means 101 finds an inference value TTTC of the input torque from a parameter relating to an automatic transmission, while a second input torque inference means 102 finds an inference value TTENX of the input torque from a parameter as to the operating condition of an engine. A learning correcting means 103 finds an inference value TTEN by correcting the inference value TTENX depending on a correcting map, and renews the correcting map depending on the difference between the inference values TTTC and TTENX. An input torque calculation means 105 calculates the final inference value TT of the input torque from the inference value TTTC and the inference value TTEN after the correction. A learning correction prohibiting means 104 prohibits the renewal of the correcting map when the engine or the automatic transmission is in a specific condition.

IPC: H02B13/02
Filed: 1994-02-18
Abstract: PURPOSE:To provide a GIS having a cable head connecting the GIS and a power cable, in which a cable bending chamber or a culvert is eliminated. CONSTITUTION:A cable head 9 to be connected with a disconnecting switch DS is within the GIS 1, and a power cable 10 to be led out vertical downward from the cable head 9 is deflected vertically by bending.

Title: Flight vehicle equipped with speed detection device
Inventor: SUZUKI HIROTO
IPC: B64C27/04
Filed: 1994-01-21
Abstract: PURPOSE:To lessen errors in speed detection in the right and left directions, and concurrently let the detecting device hardly interfere with an obstacle by providing a speed detecting wave emitting section and a reflecting wave receiving section at the longitudinal center for a landing gear which is either one of a right or a left landing gear for a flight vehicle, and concurrently directing the emitting direction of detecting waves and the receiving direction of reflecting waves to the obliquely down outward side and the obliquely down inward side respectively. CONSTITUTION:The speed detection device 18 is disposed roughly just above at the landing section 14 at the left side, it is rolled, yawed and pitched around the center of gravity G during flight, and in this place, no speed in the side-to-side direction is produced. Even if a flying craft 1 is rolled to the right side, since the emitting direction of detecting waves from a horn 28 is identical, to the receiving direction of detecting waves, reflecting waves are not changed in wave length, and its speed is not thereby detected. When the emitting direction of detecting waves from a horn 29 is different from the receiving direction of detecting waves, reflecting waves are changed in wave length, so that speed is thereby detected. Its difference measured is appropriately converted, the horn 29 is set in a place close to the center of gravity G, and detected errors are thereby small.

     CONSTITUTION: The air compressor 2 is operated at a constant speed by a driving force of an electromotor 1 to supply air required in a regeneration tower 5. When the fluidized contact decomposition apparatus reaches constant-speed operation, a flow control valve 9 is gradually opened to increase a rotation speed of the expansion turbine 3 and, when the rotation number thereof is almost synchronized with that of the air compressor 2, the fluid joint 4 is gradually connected. During this time, the rotation number of the air compressor 2 is controlled by the electro- motor 1. As described above, the operation of the power recovery apparatus can be carried out at an optional time after the fluidized contact decomposition apparatus becomes stable completely and a phenomenon of stability loss suc has afterburning or the like does not occur.
