Title: Backup system
Inventor: MIZUI KENJI
IPC: H04L12/423
Filed: 1982-07-29
Abstract: PURPOSE:To perform effective backup operation by performing automatic switching to a receivable route for communication if one route is cut off or in case of such abnormality that either slave station loses its repeating function. CONSTITUTION:When slave stations 2 and 3 are unable to receive call signals even after the elapsed time of polling through an A route 6, a time monitoring circuit 28 sends a signal to inverts the contents of a route selection memory 29, and a selector 25 receives the call signal from a B route 7. A master station 1, on the other hand, is able to receive answer signals from the slave stations 2 and 3 from the A route 6 and an answer station from a slave station 5 from the B route 7, so the time monitoring circuit does not receive the signal even the specific elapsed time later so far as the other route is selected. In this case, the contents of the selection memory are rewritten into the A route 6 for the slave stations 2 and 3 and the B route 7 for the slave station 5 to perform automatic recovery, so that there is no hindrance to communication.

A comparator 107 compares a conversion video data 20 with a triangle wave of 400 lines and outputs '1' when the conversion video data 20 is larger as the result of comparison. The output is inverted by an exclusive OR circuit 108 when the inverting signal is logical 1 and outputted as a pulse width modulation signal 25.

Title: Pressure-sensor driving circuit
Inventor: MIYAZAKI HIROSHI
IPC: G01L9/00
Filed: 1989-05-29
Abstract: PURPOSE:To improve the sensitivity of a pressure sensor even if a power source voltage is low by providing a current setting means which supplies a current that is equal to a current flowing through one strain gage resistor through another strain gage resistor. CONSTITUTION:A current which is supplied to a pressure sensor through a constant current circuit 12 from a power source 11 passes through one strain gage resistor 13. A current which has the same value as that of said current flows through another strain gage resistor 14 by the action of a current setting means 15. Therefore, even if the power source voltage is low, a large current can be made to flow through the resistors 13 and 14 in comparison with a bridge constitution. It is possible to increase the sensitivity of the pressure sensor. Therefore, it is not necessary to connect a high-gain DC amplifier circuit to a rear stage, and the peripheral circuits of the sensor can be simplified.

Title: Ic card
Inventor: KODAMA JUN
IPC: B42D15/10
Filed: 1986-06-09
Abstract: PURPOSE:To prevent the breakdown of a card due to static electricity by performing the power supply to the IC card and exchange of data signals by non-contacting means to improve the reliability for connection between a power source and the external terminal of a data input/output signal. CONSTITUTION:The projected light from the terminal is received by the second photovoltaic power source like an amorphous Si solar battery 2 mounted on the surface of the IC card to supply power to the inside of the IC card. With respect to data transmission and reception, information from the IC card is transmitted to the terminal by an LED and a driver 7, and transmission data from the terminal is received by a photo diode and an amplifying circuit 8. Thus, data are exchanged between the internal storage device of the IC card and the external without contacting. Further, the malfunction due to incidence of the light, which is projected to a solar battery light receiving part 15, to a light receiving part 13 is prevented at the time of connecting the IC card to the terminal.

Title: Channel selecting device for tuner
Inventor: NAGASHIMA YASUHISA
IPC: H04B1/06
Filed: 1987-05-28
Abstract: PURPOSE:To eliminate the need for a surface/back face switching-only key by holding a station No. received at present, comparing it with the station No. of the depressed key and using an address indicator such as a flip-flop so as to discriminate the result of comparison. CONSTITUTION:In depressing a key designating the channel 2 at a key matrix section 11, a key input circuit 12 decodes the key and a station number circuit 14 generates the data of the channel 2. Since the data of a reception station No. section 13 is the data of a 2nd channel, when the data is compared with the data of the station No. section 14 by a comparator 15, the same, e.g., data 0 is outputted. An address indicator 16 gives the instruction that it is the back face of the data 0. Then an address counter 17 outputs the address of the 5th channel being the back face of the 2nd channel by the data of the 2nd channel of the station No. circuit 14 and the discrimination signal representing the back face of the address indicator to a memory 18. Thus, the surface/back face switching-only key is not required.

IPC: G05D7/06
Filed: 1983-07-20
Abstract: PURPOSE:To improve the accuracy of flow rate control, by selecting an electric- output signal subject to a driving device for a proportional control valve from a pulse control signal to a linear control one according to the output of a flow sensor, in case of a hydraulic control device using the proportional control valve. CONSTITUTION:When the setting signal is supplied, since a signal out of a detection circuit 24 detecting a signal of a magnetic resistance element 23 in a flow sensor is zero, each of switches 30 and 31 is selected to the side of a pulse control circuit 26 by means of a level discrimination circuit 25. With this selection, a pulse signal corresponding to a deviation in the detection signal to the setting signal is outputted from the pulse control circuit 26 and fed to a coil 5 of a proportional control valve 11a. Therefore, a valve body 12 repeats on-off operation whereby a hydraulic fluid flows out by way of a flow rate sensor 13. Afterward, when a flow rate signal to be detected by the detection circuit 24 comes into a large flow level, each of these switches 30 and 31 is selected to the side of a linear control circuit 27 by the discrimination circuit 25 and thereby a linear control signal is fed to the coil 5.

Abstract: PURPOSE:To improve the operability by protecting the surface of a digitizer at the time of using cover for covering the digitizer, and switching a mode to a digitizer input receiving mode, when the cover is opened. CONSTITUTION:First of all, whether a cover 223 for covering the whole surface of a digitizer part 300 has been opened or not is checked by an output of a cover opening/closing detecting sensor 224. That is to say, a copying device switches a mode so as to receive an input first by opening the cover 223, when a user desired to set a digitizer. Unless the cover 223 is opened, a usual copy processing is executed, and when the cover 223 is opened, a digitizer setting processing is executed. When the processing is ended, ON of a copy key is awaited, and when it becomes ON, a copy processing for designating an area is executed. By this processing, a copy sheet carrying processing, a process processing, development, transfer and fixation processings, etc. are executed.

Then an up line is monitored by a reception part 13 and each time a free channel of the up line, the channel is assigned to a slave station according to order set in an address table 111. Further, an unnecessary data communication is detected with status information of the reception part and the channel allocated to the slave station is released and assigned to another slave station.
