Title: Gas detector
Inventor: KUMAGAI NOBORU
IPC: G01N27/12
Filed: 1987-02-26
Abstract: PURPOSE:To obtain a stable and proper detection output, by absorbing scattering of a resistance value of a gas detection element with a variable resistor to compensate dependence on temperature of the gas detector with the correction of an amplification factor based on changes in the resistance value of a thermosensitive resistance elements. CONSTITUTION:A resistor R of a gas detector 1 is connected to terminals P and N through a variable resistor 21. Moreover, an amplification circuit 30 comprising resistor 31, 32 and 33, a thermistor (negative characteristic) 34 and an operational amplifier 35 is connected to the terminals P and N to amplify a voltage Vg generated in the variable resistor 21. An output voltage Vs of the amplification circuit 30 as obtained when a DC voltage Vd is applied between the terminals P and N while a heater voltage Vh to a heater H is made as detection output of a gas detector. Thus, scattering of an absolute value of the resistor R can be absorbed by adjusting the variable resistor 21. In addition, the amplification factor of the amplification circuit 30 varies with changes in the ambient temperature, thereby providing a constant detection output regardless of changes in the ambient temperature.

Filed: 1988-02-26
Abstract: PURPOSE:To enable non-destructive measurement of a content ratio and an interface of an isometric part and a prismatic part on line, by irradiating a metal specimen with an ultrasonic wave to analyze a thickness-wise frequency component of the ultrasonic wave reflected. CONSTITUTION:An ultrasonic probe 2 for transmission of longitudinal waves is brought into contact with the surface of a metal specimen, for example, a slab 1 to generate a longitudinal ultrasonic wave WL by an electric signal from an ultrasonic oscillation amplifier 3. The ultrasonic wave LR reflected back on the undersurface of the slab 1 passing through an isometric part 13 and a prismatic part 14 of the slab 1 is detected with an ultrasonic probe 4 for reception. A signal is inputted into a signal processing part 7 through an amplifier 6 and an operation is performed to convert a received wave from on a time base into a waveform on a frequency base by computation several times varying a center frequency thereof by stages to obtain received waveforms on several time bases respectively confined to a plurality of frequency components. Since a frequency component of the ultrasonic wave transmitted through the slab 1 is very different between the isometric part 13 and the prismatic part 14, the isometric part and the prismatic part 14 can be judged.

IPC: F23D11/24
Filed: 1986-02-28
Abstract: PURPOSE:To prevent white smoke from being generated and tar from accumulating after the stoppage of combustion even when the temperature of a combustion chamber is not sufficiently raised by disposing a guide plate for precisely guiding a fuel oil condensed on the inner wall surface of a combustion chamber to the bottom plate of the combustion chamber. CONSTITUTION:A fuel atomized by a fuel injection nozzle 3 is ignited and combustion is started. However, a part of the atomized fuel is condensed on the inner wall surface 1 of a water can and liquefied. The liquefied fuel oil flows down along the inner wall surface 1 of the water can, and is precisely guided to the surface of a bottom plate 4 by guide plate 5 and revaporized by the bottom plate 4 whose temperature has been increased. Since the condensed fuel oil is not absorbed to fire chamber bricks, it is possible to prevent white smoke and malodor from being generated after the stoppage of combustion.

Title: Nonslip device for vehicles
Inventor: WAKATA HIDEO
IPC: B60W10/10
Filed: 1984-03-07
Abstract: PURPOSE:To prevent a driving wheel from its excessive speed drop or the like as well as to keep off any drop in running accelerability and drivability, by estimatingly compensating a lever after a slip judgment is over, from a speed variation in the driving wheel or the like in time of driving torque controlling. CONSTITUTION:Each speed signal out of a driving wheel speed detecting device (a) and a driven wheel speed detecting device (b) is inputted into a controlling device (c) which judges a state of slippage in a driving wheel from the variation state of these signals and outputs a torque reduction signal. With this signal, a torque controlling device (d) reduces the driving torque of a driving system (f) and transmits this reduction to a driving wheel (g). On the other hand, a level changing device (e) estimates the effect of responsive lag time from a speed variation in the driving wheel or the like in time of driving torque controlling and thereby compensates the level after a slip judgment is over. With this constitution, any drop in speed of the driving wheel and control chattering and the like are prevented from occurring and, what is more, keeping off any drop in running accelerability and drivability.

Title: Haar converter
Inventor: TACHIBANA YASUO
IPC: G06T9/00
Filed: 1979-04-12
Abstract: PURPOSE: To make it possible for a simple circuit to perform Haar conversion at a high speed by using two integral A/D converters alternatively.  
     CONSTITUTION: Gate waveform generating circuit 1 generates gate waveform P 1  and pulse P 2  from a signal showing timing pulse S and integral period T. Waveform P 1  becomes logic "1" synchronizing with the rise point of pulse S and alternates logic "1" with "0" at period T. Gate circuits 2, 3, while waveform P 1  is logic "1" or "0", allow signal X(v) to pass through and it is input to integral A/D converter 5 or 6. Converter 5 integrates signal X(v) for period T and when waveform becomes logic "0", the integral value is A/D converted before being output to AND gate 7. Converter 6, on the other hand, integrates signal X(v) for period T and when waveform P 1  becomes logic "1", the integral value is output to AND gate 8 being A/D-converted. The outputs of gates 7 and 8 are input in parallel to register 10 via OR gate 9 at the point in time of pulse P 2  and register 10 outputs sequentially output X 11  varying at every period T.

Abstract: PURPOSE:To suppress the pulsation of a rotor bar at the rotating time by forming the bar in a wavy shape, forming a linear slot on one end of the bar in the state that a spring action is provided in a slot, thereby uniformly providing a holding force in the slot. CONSTITUTION:A rotor bar 9 is formed in a wavy shape, and inserted into a slot 2. A gap 10 between the bar 9 and the slot 2 varies according to the position of the lengthwide direction of the bar 9.

In this case, the gap 10 varies in the lengthwise direction of the bar 9, but uniform state is always maintained in the gap 10 between the inner wall of the slot 2 and the bar 9. Then, when linear slots 7 are arranged by a chisel 8, one end of the bar 9 uniformly contacts the inner wall of the slot 2, and stable holding and securing force is obtained from the inner wall of the slot 2 to the pulsating force due to the centrifugal force and external force acting on the bar 9.
