Filed: 1992-03-27
Abstract: PURPOSE:To prevent supply of charging power in a state that a charging cable is removed by starting charging after an AC current flowing to an AC circuit formed by connecting a capacitor between terminals of connectors of a charger side and a side to be charged is detected. CONSTITUTION:When a relay 17 is operated by a relay controller 9-2 to close a contact 14, an AC voltage of a secondary winding of a transformer 12 is applied to external connection terminals A, B.

Title: Line exchange system
Inventor: MIYAMOTO NAOYUKI
IPC: H04L12/58
Filed: 1990-03-19
Abstract: PURPOSE:To prevent redialing from a calling terminal equipment and to avoid the extension of a relay line by providing a means calling a terminal equipment and a means sending a data to a deputy receiver. CONSTITUTION:When a terminal equipment 12-2 is called from a terminal equipment 12-1 and the called terminal equipment 12-2 is busy or the called terminal equipment 12-2 is a G3 facsimile equipment, since a data sent from the caller terminal equipment 12-1 is received and stored by a deputy receiver 16 in place of the called terminal equipment 12-2, redialing resulting from the called terminal equipment 12-2 called repetitively by the caller terminal equipment 12-1 is prevented. Thus, the increase in incomplete calls due to redialing of the caller terminal equipment 12-1 is effectively suppressed, resulting that it is not required to extend an expensive relay line 60. Moreover, since the deputy receiver 16 is automatically called in place of the called terminal equipment 12-2, it is not required to store a telephone number of other called terminal equipments by the caller or to memorize the procedure operation of mail transmission, resulting that the transmission is very easily implemented.

Title: Semiconductor relay circuit
Inventor: INOUE KIYOKAZU
IPC: H05B39/02
Filed: 1980-05-23
Abstract: PURPOSE: To reduce the electric power loss to be applied to a transistor even in case when the load impedance is small, by increasing furthermore the base current only when the voltage is higher than a prescribed level at the point of connection between a load and the transistor.  
     CONSTITUTION: When a switch 4 is closed, the current IBS is supplied to the base of an output stage transistor (TR) 2 from a DC power source 5 through a base resistance 1. On the other hand, the voltage higher than several Vs is applied between C and E of the TR2 immediately after a closure of the switch. As a result, the current IB 6  flows to the base of a driving TR6 through a resistance 7, and the emitter current of the hFE-times value is applied to the current IBS to be flowed to the base of the TR2. Thus a load current having a sufficiently large value is supplied to a ramp load 3. The C-E voltage of the TR2 is lowered down as the time passes. Thus the TR6 is cut off and only the current IBS exists as the base current of the TR2. Then the steady current is supplied to the load 3.

Filed: 1980-05-27
Abstract: PURPOSE:To detect leakage with a high sensitivity at a lower cost in a simple handling manner by detecting an unbalanced output voltage of a bridge circuit into which a leak detecting sensor containing a resistance wire is incorporated.

Abstract: PURPOSE:To provide the noncontact IC card which enables internal data to be read out of its memory even if a noncontact type transmission and reception part for transmitting and receiving the data of the noncontact IC card to and from the outside gets out of order. CONSTITUTION:A CPU 3 makes a memory management part 2 to read data out of the memory 1 and outputs the data to the noncontact transmission and reception part 4, which outputs the data to the outside. When the transmission and reception part 4 receives data, the data are stored in the memory 1 through the memory management part 2. When no data are inputted to or outputted from the noncontact transmission and reception part 4, the CPU 3 judges that the transmission and reception part 4 gets out of order, and switches the transmission and reception of the data to a stand-by noncontact transmission and reception part 5. Data are transmitted and received through the stand-by transmission and reception part 5 thereafter.

Title: Recovering method for sulfur from gas containing hydrogen sulfied and sulfur dioxide as well as dust
Inventor: KATSURAHARA KAZUTAKA
IPC: B01J23/745
Filed: 1980-05-28
Abstract: PURPOSE:To recover sulfur without causing catalyst deterioration and clogging due to dust by passing a gas contg. H2S and SO2 in a specified molar ratio as well as dust through a Claus reactor packed with a catalyst of metallic oxide deposited on a TiO2 carrier. CONSTITUTION:A Claus reactor 2 is packed with a honeycomb catalyst of metallic oxide deposited on a TiO2 carrier or a plurality of catalyst pipes, and a gas contg. H2S and SO2 in 2:1 molar ratio as well as dust is passed through the reactor 2 downward from a raw gas line 1 in the longitudinal direction of the catalyst. By inhibiting the dust-contg. gas from flowing across the honeycomb side wall or the tubular wall, the clogging of the porous side wall due to dust is prevented. This catalyst is not deteriorated in the catalytic performance owing to HCl and NH4SO4 in the gas. Sulfur formed by the Claus reaction is condensed with a condenser 3 and recovered from a line 4. The uncondensed gas is exhaused from a line 5.

Title: Stereophonic sound-image display system

Filed: 1979-06-08
Abstract: PURPOSE:To make the sense of hearing coincide with a wave-form by finding the sum signal and difference signal of the L signal and R signal of a stereophonic signal and by displaying them on CRT. CONSTITUTION:The L signal and R signal of a stereophonic signal to be observed are supplied to sum/difference circuit 1 to obtain sum signal L+R and difference signal L-R. Then, the L+R signal is added to the Y-axis of CRT2 and the L-R signal is also added to the X-axis to display the sound image waveform of the stereophonic signal. As a result, the display comes into effect so that while an L-directional sound, R-directional sound and center-positioned sound are in the L direction, in the R direction and in the center, the spread of a composite signal will be horizontal. Therefore, the spread of the horizontal component of a real musical sound, etc., can be felt from the entire waveform drawn on CTR2. Thus, the sense of hearing can be made to coincide with the waveform.
