Inventor: HINAKO HIDENORI
IPC: C07C253/24
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently produce nitrile without allowing a promoter to be present by preparing a catalyst used adequately for the case the nitrile is produced by subjecting alkane to gaseous phase contact oxidation by molecular oxygen and ammonia from metallic oxide of an Mo-Bi-Ce-Co-X system.

Title: Astable multivibrator using cmos-nand circuit
Inventor: SASAKI HIROBUMI
IPC: H03K3/03
Filed: 1982-09-30
Abstract: PURPOSE:To prevent destruction of elements with a simple constitution by using a diode and suppressing an input voltage of a CMOS-NAND circuit within the maximum ratings. CONSTITUTION:When a CMOS-NAND element N2 is turned off, a potential at a terminal O2 is increased to a power supply voltage VDD, and a capacitor C2 is charged via a variable resistor R2 and a diode D2. Thus, a voltage at an input terminal g2 is increased as shown in figure A, the 2nd CMOS-NAND element N1 is activated at a point of time t2 where the voltage is restored to a cutoff threshold voltage VTH with time constant C2(R2+rd2) decided by the circuit constant, and when the loop gain exceeds 1, the on/off state is inverted and the element N1 is turned on. Although the voltage at the input terminal g2 is increased rapidly as shown in figure A, it is clamped instantly to the power supply voltage VDD with the presence of the diode D2, and the CMOS-NAND element is protected from the voltage destruction.

When a voltage is applied with the electrode 5 as a positive side, carrier is injected to a GaInN light emitting layer, thereby emitting a blue color of approx. 4800nm. Carrier flows also to an AlGaInN current injection 2, but band gap difference is approx. 0.4eV, reactive current is reduced by the effect of band discontinuity, thin to 0.5mum, and a light is emitted in high efficiency of 1% of external quantum efficiency even with the low resistance light emitting layer as compared with a conventional one.

Title: Method for displaying outdoor air temperature
Inventor: SUZUKI TOYOMITSU
IPC: B60H1/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To highly accurately display a temperature outside a vehicle in a simple constitution by displaying an outside air temperature immediately before a predetermined engine stop period passes if an outside air temperature when the vehicle starts before the predetermined engine stop period passes is higher than the outside air temperature immediately before the stop period, and displaying an outside air temperature when the vehicle starts after a stop period not shorter than the predetermined time. SOLUTION: When a vehicle is stopped and an ignition switch 23 is turned off to stop the rotation of an engine, a control part 21 stores an outside air temperature TOFF immediately before the ignition switch is turned off which is detected by an outside air temperature sensor 22. When the switch 23 is turned on within a predetermined time after the switch is turned off, e.g. in one hour, and if a detected outside air temperature Tn is higher than the outdoor air temperature TOFF immediately before the switch is turned off, the outdoor air temperature TOFF is displayed at a display part 17 of a liquid crystal display 16. When the switch 23 is turned on after the predetermined time has passed, the outdoor air temperature Tn detected at the time is displayed. Therefore, the outdoor air temperature can be displayed highly accurately without being influenced by the engine.

Title: Control method of dc servo motor
Inventor: YAMAGISHI MASARU
IPC: H02P3/08
Filed: 1991-07-15
Abstract: PURPOSE:To improve control characteristic by increasing or decreasing duty of a control pulse signal for a deviation compensating value against a reverse electromotive force induced on a motor by each target speed at the start-up time of motor. CONSTITUTION:A speed detector 2 detects an actual rotating speed Vr of a motor 1 and a comparator 3 obtains a deviation (e) by comparing the target speed VTG with the actual speed Vr. The target speed setting circuit 4 obtains the target speed VTg for each unit time for control of the motor 1 and sets this target speed to the comparator 3 and a duty decision circuit 5. The duty decision circuit 5 increases or decreases a duty value for compensating deviation output from the comparator 3 depending on the type of control such as the accelerating operation or braking operation based on reverse electromotive voltage value of the preset target speed VTG and polarity of deviation. Thereby, control characteristic can be improved.

Filed: 1992-06-08
Abstract: PURPOSE:To achieve a prevention of erroneous detection of an address mark or the like by making a second synchronous signal contain none of the shortest inversion pattern continuing from the first synchronous signal containing the shortest inversion pattern in a digital modulation rule. CONSTITUTION:An input data DTi is inputted sequentially into a shift register SR synchronizing a clock CKr and data to be applied to one input terminal of AND circuits AN1-AN16 changes every time each CKr is outputted.

Then, the number of the AN circuits where the outputs of the AN1-AN16 are at an logical H level is counted with a coincidence number counter CT. When the number of coincidences is 16, an AM detection signal DTam is outputted from a comparator CM thereby reducing probability of erroneous detection of the AM.

IPC: F01C1/02
Filed: 1982-10-05
Abstract: PURPOSE:To improve output efficiency by substantially reducing to zero the volume of a central cell formed between engaging points of spiral bodies at the stationary and turning sides in the relative turning of both spiral bodies. CONSTITUTION:When the stationary side spiral body 501 and the turning side one 502 revolve relatively, the volume of a small cell 553 formed between engaging points 552, 552' is reduced and finally the points 552, 552' coincide with each other to reduce the volume of said cell 553 to zero. Thus, since top clearance volume becomes zero, compressed fluid is wholly discharged from a discharge port to the outside so that work given the fluid by a compressor is wholly given to the fluid.

Filed: 1994-07-26
Abstract: PURPOSE:To select/demodulate an HH signal and a multiplex signal in one demodulation part by guiding the multiplex signal frequency-multiplexed by a non-picture part to the demodulation part, generating the carrier signal of the frequency fsc from a carrier generation circuit and switching a filter circuit so that an LPF characteristic for multiplex signal is given. CONSTITUTION:A video signal inputted by a timing generation circuit 81 is discriminated to be the main picture part of a letter box system or a top/bottom non-picture part. When it is the main picture part, the HH signal which is frequency-multiplexed in the main picture part is guided to the demodulation part 83, the carrier signal of the frequency 16/7fsc is generated from the carrier generation circuit 87 and the filter circuit 88 is switched so that a BPF characteristic for HH signal is given. When the video signal is judged to be the top/ bottom non-picture part, the circuit 88 is switched so that the LPF characteristic for multiplex signal is given. Thus, one demodulation part 83 selectively demodulates the HH signal and the multiplex signal and the scale of the circuit required for the demodulation processing of the frequency multiplex signal is reduced so as to realize miniaturization.
