Title: Mechanical supercharging device for engine
Inventor: TADOKORO ASAO
IPC: F02B27/02
Filed: 1987-03-24
Abstract: PURPOSE:To obtain an output characteristic without a torque shock by changing an intake characteristic when engine speed reached a switchover engine speed, while changing the speed of a speed change mechanism which transmits power to mechanical supercharger to a high speed stage when the engine speed reached a speed-change engine speed which is lower than said switchover engine speed. CONSTITUTION:An intake characteristic variable means 51 which can vary the length of an intake passage through the opening/closing of a selector valve, is controlled so as to change an intake characteristic when engine speed becomes a defined switchover engine speed, by an intake characteristic control means 52 which receives the output of an engine speed detecting means 22. Also, a speed change mechanism 10 having stages which changes the rotating speed of a supercharger 9 in plural stages is provided in between the engine-driven supercharger 9 and an engine 1, and is controlled so as to change speed from a low speed stage to a high speed stage when the engine speed becomes a defined speed-change engine speed, by a speed change control means 53. In this case, the speed-change engine speed for the speed change control means 53 is set on a lower speed side than the switchover engine speed for the intake characteristic control means 52.

Title: A/d conversion circuit and a/d conversion method
Inventor: OHASHI TAICHI
IPC: H03M1/08
Filed: 1992-02-20
Abstract: PURPOSE:To eliminate random noise by applying arithmetic mean to analog signals sampled at a high frequency or digital signals converted corresponding to the sampling so as to obtain a digital output signal. CONSTITUTION:Sampling is applied at a higher frequency than an A/D conversion frequency. Plural input signals corresponding to noise are latched through the operation above. That is, plural sampling values obtained by the oversampling are random combinations of larger and smaller values with respect to an ideal value. The sampling values are subjected to arithmetic mean processing, a noise component included in a larger sampling value with respect to the ideal value and a noise component included in a smaller sampling value with respect to the ideal value are cancelled together to obtain a sampling signal close to the ideal value. The arithmetic mean signal formed in this way is fed to the A/D converter, from which a digital signal is obtained.

Title: Zinc oxide single crystal having variation of electric conductivity in crystal axis direction
Inventor: ASAI YUJI
IPC: H01L41/18
Filed: 1993-03-29
Abstract: PURPOSE:To obtain a ZnO single crystal having electric conductivity in one single crystal which can deal with a wide frequency range used for ultrasonic inspection of various materials to be measured by forming such a ZnO single crystal that shows variation of electric conductivity in the a-axis or c-axis direction. CONSTITUTION:The ZnO single crystal shows variation of electric conductivity in the a-axis or c-axis direction. Even when ultrasonic inspection is performed by using frequency in the frequency range (10kHz-50MHz) usually used for ultrasonic inspection, the ultrasonic wave of this frequency passes through the ZnO single crystal area showing proper acoustoelectric exchange characteristics for this frequency when the ultrasonic wave of this frequency passes through the ZnO single crystal. By this method, sufficient detection sensitivity can be obtd. for a wide frequency range.

The spectrum f(v) measured in the position P2 is subjected to frequency transfer, inversion and scale conversion etc. in a signal analysis part 5 and is subtracted from the actually measured spectrum h(v) in the position P2, by which the spectrum having no folding is calculated. The wave number spectrum g(v) eliminated of the influence of the folding from the wave number spectrum h(v) in which the folding arises is obtd. by this computation. The wave number resolution is thus improved.

Abstract: PURPOSE:To prevent an accident of burning a stabilizer when a luminous tube is lighted in case Xe leaks out into an outer tube due to leakage of a luminous tube by dividing a coil filament so as to impress opposed potential between the parts neighboring each other of the divided filaments. CONSTITUTION:When voltage is impressed on a lamp in a state in which Xe or the like, which is an enclosure, is leaked out into an outer tube 1 due to leakage of a luminous tube 3, coil filaments 10 and 11 are conducted and heated at a lamp starting time and both filaments emit thermal electrons alike while ionizing Xe existing around and both filaments function as thermal cathode alike. Further the end parts 10a and 11a of both filaments are close-facedly arranged so that the highest potential in the circuit is impressed between said end parts 10a and 11a thus generating easily discharge even in a state of low Xe pressure while leading to burn-out of filaments. The burn-out stops operation of a heat- acting switch 9 so as not to light the luminous tube 3 having a leakage thus to prevent the stabilizer from burning.

Filed: 1995-03-29
Abstract: PURPOSE: To provide a display device capable of easily displaying massive information with simple constitution. CONSTITUTION: A rotational speed ratio of a feeding side reel to a take-up side reel of a tape is obtained. When tape running is started in the state that all tape is wound up around the feeding side reel, since the rotational speed of the feeding side reel is later than the rotational speed of the take-up side reel, the ratio between the rotational speeds becomes, for example, 0.35 or below. Here, seven pieces among light emitting diodes 11-18 are made to be lighted, and the lighting light emitting diodes are switched successively related to the tape running. When the tape is wound up around the take-up side reel, the rotational speed ratio becomes large. The number of lighting light emitting diodes are reduced according to the rotational speed ratio.  When nearly all tape is wound up around the take-up reel, and the rotational speed ratio is 2.75 or above, the number of lighting light emitting diodes are made one. The tape running state is recognized by the order of the lighting and a switching speed, and the remaining tape is obtained by the number of lighting light emitting diodes.
