Inventor: ENMANJI KIMIE
IPC: G01N27/416
Filed: 1992-05-06
Abstract: PURPOSE:To measure a bad smell in a gas, e.g. in the air, by a method wherein a bad-smell sensor is constituted of a field-effect transistor whose semiconductor is a conductive polymer whose potential is changed by adsorbing a bad-smell substance. CONSTITUTION:A bad-smell sensor is constituted of the following: a gate electrode 1 used also as a substrate; an ohmic electrode 2; an insulating film 3; a conductive polymer film 4 as a semiconductor; a source electrode 5; and a drain electrode 6. For example, polythiophene, polypyrrole, polyacetylene or the like can be used for the conductive polymer film. When a bad-smell substance is adsorbed to the sensor, a potential is generated on the conductive polymer film 4, and the potential is measured by means of a field-effect transistor. When at least one kind out of cyclodextrin and metal polyolefin is added to the conductive polymer film 4, the cyclodextrin or the metal polyolefin is bonded strongly to the bad-smell substance, and the sensor becomes sensitive to even a low bad-smell concentration.

Title: Separation circuit for carrier chrominance signal
Inventor: TANAKA YUTAKA
IPC: H04N9/78
Filed: 1980-08-19
Abstract: PURPOSE:To eliminate cross color at vertical noncorrelation section, by applying a pair of color video signals being inverse relation to an amplitude correlator, outputting a signal having smaller amplitude only when the polarity of both the signals and picking up the carrier chrominance signals component only. CONSTITUTION:A color video signal Si is separated into a high band component Yh in a liminance signal and a signal Sa including a carrier chrominance signal Sc at an HPF2. Among the signal Sa applied to a separation circuit 10, one is directly applied to an amplitude correlator 20 and another is a signal -Sa of inverse phase delayed by one horizontal period with a delay circuit 11 and an inverter 12 to be applied to a correlator 20. It discriminate the correlation of amplitudes between the signals Sa and -Sb and only when the apmlitude of both the signals is of the same polarity, a signal having smaller amplitude is outputted. Thus, only the signal Sc component not including the signal Yh is outputted from the correlator 20. Then, since the cross color produced at a vertical noncorrelation section can be eliminated with a simple constitution, the improvement of the video quality can be made.

Title: Power feeding system
Inventor: KOJIMA TAKUTO
IPC: H04M19/00
Filed: 1980-08-19
Abstract: PURPOSE:To make circuit integration feasible in a power feeding circuit and to reduce unbalanced grounding, by constituting electronic components only without using electromagnetic components such as chockes and transformers, for a power feeding circuit. CONSTITUTION:A voltage between terminals 1, 2 of a power feeding circuit SP is divided at a voltage division circuit VD, and the output voltage is charged to a voltage-current conversion circuit V-I via an LPF. Since resistors R2, R3 of the circuit VD are set to a sufficiently large value, the voltage dividing voltage by an AC voltage superimposed on the terminal 1 is made small and further smoothed at the LPF. Thus, even if the voltage at the terminal 1 is changed by an audio current, the change in the current flowing to the voltage-current conversion circuit V-I is almost zero, the AC impedance between the terminals 1, 2 of the circuit SP comes to the sum of the resistors R2 and R3, allowing to obtain sufficiently greater value, and requirements as the call current supply circuit can be satisfied.

Title: Analog/digital converter
Inventor: MURAKI KENJI
IPC: H03M3/02
Filed: 1988-05-11
Abstract: PURPOSE:To obtain a digital signal whose dynamic range is wide by using delta modulators(DM) with different quantization step widths, and outputting the outputs of those as switching them. CONSTITUTION:The first DM of the quantization step width of DELTA is constituted of a first subtracter 102, a first quantizer 103 and a first local modulator 104, and the second DM of the quantization step width of a DELTA is constituted of a second subtracter 106, a second quantizer 107 and a second local demodulator 108. By comparing a level at which overload occurs and the output of an amplifier 110 by the first DM, it can be decided whether the overload is being caused in the first DM or not. Then, a switch 112 is controlled so as to output the output of a first DLPF(digital low pass filter) 105 when the overload is not being caused, and so as to output the output of the amplifier 110 when the overload is being caused. Thus, the dynamic range can be expanded.

IPC: A01C11/02
Filed: 1994-04-28
Abstract: PURPOSE:To reduce the weight of a transplanting member by shortening the length of a spring for holding the transplanting member in a horizontal state. CONSTITUTION:A spring 37 is spread between a neighbor of the supporting point of a lower link of a lower link-supporting shaft 30 of a linking mechanism 3 for vertically driving a transplanting member 5 and a drive case 35 for transmitting a power to a transmission placed in a planter case 46. Through this mechanism, horizontal balance of the transplanting member 5 is held even in the case where the mobile machine body 2 tilts. Further, even in the case where a the lower link-supporting shaft 30 is rotated by the rolling motion of the transplanting member 5 or by the vertical motion of the linking mechanism 3, a spring supporting member 30a is rotated so that the spring 37 is spread in the shortest length and a forced stress on a hook part 37a of the spring 37 is avoided, thus the transplanting member 5 is held in a horizontal state.

Abstract: PURPOSE:To realize the amplification of good power efficiency without deteriorating an out-band spectrum by dissolving a signal with envelope variation into the constant envelop modulated waves of two systems, and synthesizing these constant envelope modulated waves of two systems after amplifying them respectively. CONSTITUTION:A waveform generating arithmetic means 12 inputs orthogonal- modulated signals I(t), Q(t), and outputs first orthogonal-modulated signals I1(t), Q1(t), and second orthogonal-modulated signals I2(t), Q2(t) respectively consisting of two orthogonal-modulated signal components. Here, the first orthogonal- modulated signals I1(t), Q1(t) and the second orthogonal-modulated signals I2(t), Q2(t) are generated so that an input signal is regenerated by synthesizing them. Two orthogonal-modulated means 13, 14 modulate carrier waves by orthogonal- modulated signals to which they correspond respectively, and output the constant envelope modulated waves S1(t), S$2(t) of two systems, and after being amplified by amplifying means 15, 16 to operate in the saturation area of the high power efficiency, they are summed by a synthesizing means 17, and an output signal is obtained. Thus, a signal wave with the envelope variation can be amplified as holding its linearity and keeping the high power efficiency.

Title: Production of silicon steel sheet having silicon concentration distribution using siliconizing method
Inventor: KASAI KATSUJI
IPC: C22C38/02
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To form a prescribed Si concn. distribution, to suppress the generation of pushing flaws on a steel sheet surface in a furnace and to improve a surface shape by penetrating Si into the steel sheet from its surface by using a vertical type furnace, then executing a diffusing treatment and stopping the diffusing treatment while there is an Si concn. gradient in the thickness direction of the steel sheet. SOLUTION: The steel sheet S is continuously treated by using the vertical type furnace arranged with a heating furnace 1, a siliconizing treatment furnace 2, a diffusing treatment furnace 3 and a cooling furnace 4 successively from below in a perpendicular direction. The steel sheet S is heated at about 1200 deg.C in the heating furnace 1 and thereafter, gaseous SiCl4 is introduced into the siliconizing treatment furnace 2 and the Si is penetrated into the steel sheet S surface in a non-oxidizing gaseous atmosphere contg. the gaseous SiCl4 . The steel sheet is then subjected to the diffusing treatment in the non-oxidizing gaseous atmosphere in the diffusing treatment furnace 3. While the Si concn. gradient exists in this diffusing treatment, the diffusing treatment is stopped and the diffusing rate is so controlled that the desired Si concn. distribution is formed.  The in-furnace residence time of the steel sheet is, therefore, shortened and the probability of the deformation by high-temp. creep and the breakage in the furnace may be lowered.
