Title: Basic pulse operating system of hot-wire type flowmeter
Inventor: FUKUSHIMA MASASHI
IPC: G01F1/72
Filed: 1979-04-23
Abstract: PURPOSE: To make possible fuel injection controlling which is unaffected by the pulsation of suction air amount by sampling the output voltage of the hot-wire type flowmeter and deriving fuel pulses from the mean suction air amount added and averaged at every period for one revolution of the engine.  
     CONSTITUTION: The output voltage of the hot-wire type flowmeter 1 which measures the instantaneous velocity of flow of the suction air to the engine is sampled at every periodic pulse of a timing pulse generator 6 by an A/D converter 2 and is digitally converted. It is then input to a computer 7 which in turn calculates suction air amount Q in . The period τ for one revolution of the engine is detected by a revolution sensor 4 and the added value QAD and addition times NAD of the suction air amount Q in  over the period τ are counted by the computer 7 and the mean suction air Q'=QAD/NAD is computed. The mean suction air amount Q' is divided by the number of revolutions N of the engine to obtain the pulse width TP of the fuel injection pulses, i.e., basic pulses and if a fuel injection solenoid valve 9 is controlled by this, the stable fuel injection controlling may be accomplished even if the output of the hot-wire type flowmeter pulsates.

Abstract: PURPOSE: To miniaturize and simplify a bill checker, and enhance the reliability and maintenance, by judging the length of banknote by means of detecting means to measure the quantity of transmission of a set of light and pulse generator.  
     CONSTITUTION: When sensors H1, H3 detect a banknote and signal h is outputted from a waveform shaping circuit 21, reading of banknote pattern by sensors H1 to H4 is started. A counter 16 is stepped by output pulses of a pulse generator 17. When the counter 16 specifies H1, a light emitting part 200a is driven, and when H3 is specified, a light emitting part 205a is driven, so that an amplifier 9 may be used commonly for H1 and H3. A counter 25, while H1 and H3 are detecting a banknote, counts the pulses inputted into the counter 16, and the count value thereof corresponds to the length of the banknote being transferred. A control circuit 1, when H1 and H3 come to detect no banknote, judges the approval or disapproval of the length of the banknote and processes accordingly.

IPC: H01L29/76
Filed: 1987-03-09
Abstract: PURPOSE:To contrive the improvement of a current amplification factor by a method wherein the electron affinities and thicknesses of a layer structure consisting of a semiconductor, an insulator and a metal or a superconductor are made properly. CONSTITUTION:As the electron affinities of second and fourth Al0.3Ga0.7As layers 2 and 4 are small compared to those of first and third GaAs layers 1 and 3, a potential barrier of about 0.3 eV to that in the layers 1 and 3 is formed in the layers 2 and 4. The thickness of the layer 3 is set in the degree of a de Broglie wavelength or less in the GaAs layer. In such a constitution, when a forward voltage VEB is applied between an emitter 7 and a base 8, the electrons of a first InSb semiconductor layer 6 are injected in a layer 5. These electrons are hot electrons 0.2 eV higher in energy than the electrons of the layer 5 and as the quantum energy level coincides with the quantum energy level produced in the layer 3, the hot electrons are tunneled in the layer 1 by a resonance tunneling phenomenon and are turned into a collector current IC. Accordingly, a base current IB does not flow and the current amplification factor of the grounded base is improved.

Abstract: PURPOSE:To obtain a coating composition excellent in moisture permeability and carbon dioxide impermeability, by using a water-dispersible coating resin and diatomaceous earth and specifying the pigment volume concentration and the diatomaceous earth content. CONSTITUTION:This coating composition comprises a water-dispersible coating resin and diatomaceous earth and has a pigment volume concentration of 30-50% and a diatomaceous earth content of 50-150pts.wt. per 100pts.wt. resin solid. Examples of said water-dispersible coating resin include acrylic, acrylic/styrene, vinyl acetate and vinyl chloride resins and natural and synthetic rubbers. This composition is applied to an inorganic building material or the like by spraying, roller coating or brush coating. When the coating weight is small, the coating film is insufficiently effective in preventing carbonation through it is effective in preventing dew condensation. When the coating weight is large, a risk of forming dews arises through the coating film is sufficiently effective in preventing carbonation. Therefore, a suitable coating weight is desirably in the range of 300-1,000g/m<2>.

Title: Method for removing commercial frequency in cable fault point detection
Inventor: WATANABE NARUTOSHI
IPC: G01R31/08
Filed: 1980-04-21
Abstract: PURPOSE:To make highly accurate detection of fault points possible without receiving the influence of commercial frequencies by sampling a multiplicity of measuring signals in the common multiple time of the period of the commercial frequency thereby negating the superposed commercial frequency components. CONSTITUTION:Measuring voltages are sampled in multiplicity in the common multiple time of the period of a commercial frequency 50 or 60Hz, whereby the commercial frequency components are negated. For example, if the maximum input signals of an analog/digital converter 4 are assumed to be -5V-+5V, and the absolute value of the signal entering the converter 4 is assumed to be 7V, the superposed components of the commercial frequency are permitted up to 3Vp-p. If this signal is measured 300 times during, for example, 100ms, only the commercial frequency components are negated. Then, the fault point detection of high accuracy is made possible without receiving the influence of the commercial frequencies.
