Abstract: PURPOSE:To improve the operating efficiency of a network, by transmitting a signal from a terminal device to a star repeater by the light in another wavelength during the use of a network, storing the signal once and transmitting the signal to each terminal device when the network is idle. CONSTITUTION:When a transmission request comes from a terminal device 10, a transceiver 20 detects whether or not the network is busy at a collision detector 36, and when empty, signals are transmitted after being converted into a light in a wavelength lambda1 via a control circuit 22, converted into electric signals at a photo detector 56A of a star repeater 50, inverted into the light in wavelength lambda1 at a converter 78 via a multiplexer 62, and transmitted to the transceiver 20. When the network is busy, the output of the device 10 is converted into a light in wavelength lambda2 via the circuit 22, and transmitted after being synthesized with the light in the wavelength lambda1 at a filter 52. Further, the signal is stored in a memory 66 in the repeater 50 after being separated into the signal in the wavelength lambda1 at a filter 52. When the network is idle, the signal is transmitted to the device 20 via a control circuit 64.

Title: Ignition device for internal combustion engine
Inventor: YUGAWA HIDEKI
IPC: F02P5/155
Filed: 1986-03-28
Abstract: PURPOSE:To make it possible to smoothly spark-retard the ignition timing in a range of rotational speed at which spark-retardation is initiated, by delaying charge to an ignition timing control capacitor for a predetermined time period in a range of rotational speed exceeding the spark-retardation initiating speed. CONSTITUTION:A switch means control circuit 6 detects the rotational speed of an engine and performs such control that a switch means 5a in a partially dividing ratio control circuit 4 is closed for a predetermined period when the rotational speed exceeds a spark-advance initiating speed. Therefore, a resistor R6 is connected in parallel to a resistor R5 in a trigger signal supply circuit 4 to lower the output voltage of a partial divider circuit to delay electrical charge for an ignition timing control capacitor C1 to delay a phase with which the terminal voltage of the capacitor reaches the trigger level of a transistor Tr2 in a shut-off control switch circuit 3, resulting in spark-retardation of the ignition timing. Meanwhile, when the switch means 5a is opened, the charging time constant of the capacitor C1 is returned to its original value. Thus, it is possible to smoothly spark-retard the ignition timing in association with an increase in the rotational speed in the spark-retardation initiating speed range.

Filed: 1982-04-27
Abstract: PURPOSE:To obtain a valve that can be readily adjusted and has a simple construction, by arranging a pilot chamber over a secondary pressure chamber, providing a planar temperature-sensitive element of a configuration memory alloy in the pilot chamber, and moving a piston by the action of the element to open or close a main valve port. CONSTITUTION:When a refrigerant of a low temperature enters the pilot chamber 35 from an opening 41, the temperature-sensitive element 37 is deformed by the resiliency of a spring 39 to cause a pilot valve body 40 to close a pilot hole 34 of a partition 33 of a cylinder 24. Then the refrigerant in the secondary pressure chamber P is drawn by the operation of a compressor connected to a case 21 so that the chamber P is negatively pressurized and the piston 27 is raised by a spring 28 to throttle the opening of the main valve port 26. When the temperature of the evaporator connected to the case 21 becomes a prescribed value or above, the temperature-sensitive element 37 returns to the position as shown in the figure, the pilot valve body 40 is raised to open the pilot hole 34, the refrigerant passed through the pilot hole 34 lowers the piston 27 against the spring 28 via the partition 31 of the piston 27, and a control valve port (a) of the piston is aligned with the main valve port 26 to widen the opening of the main valve port 26.

Title: Method for driving optical sub-carrier modulator and driving circuit
Inventor: DOI YOSHIYUKI
IPC: H04B10/564
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To suppress an unnecessary side robe superposed on an output light sub-carrier and to suppress a noise owing to the interference of a light area by compressing the pulse time width with an input data signal and driving a light sub-carrier modulator through the use of a driving signal where a higher harmonic component is suppressed. SOLUTION: The pulse time widths of input data and inverted input data are compressed by pulse compressors 5a and 5b. The higher harmonic component of a pulse is suppressed in LPE 6a and 6b and a prescribed bias voltage (V1+V2)/2 is superposed. The driving voltage of an MZ modulator 13a and the driving voltage of an MZ modulator 13b are obtained. In light sub-carries outputted form the MZ modulators 13a and 13c, overlap does not occur in a complementary switch operation by the compression of the pulse time widths of respective driving voltages. Intensity strength by interference in a light area is suppressed. Also, an unnecessary side robe which is superposed on the output light sub-carrier is suppressed by the suppression of the higher harmonic component of the pulse.

Title: Water level detector for washing machine
Inventor: YAMAMOTO TOSHIYOSHI
IPC: G01F23/14
Filed: 1979-06-05
Abstract: PURPOSE: To ensure the continuous and high-accuracy detection for the water level of the washing machine and via a compact device, by extracting electrically the displacement of the water amount and in the form of the electrostatic capacity.  
     CONSTITUTION: Plate 4 of one side of the plate pair in electrostatic capacity detector 2 is formed with the foil of the print substrate, and then detecting circuit 5 is incorporated onto plate 4. When the water level of the washing machine rises up due to the supply of water, the pressure within diaphragm 1 increases. As a result, mobile part 1a of diaphragm 1 has the malformation, and then plate 3 attached to diaphragm 1 functions. Accordingly, the relative position to plate 4 changes, and thus the electrostatic capacity has a change. This change of the electrostatic capacity is extracted in the form of the change of the frequency by detecting circuit 5 provided on the same print substrate, and then compared with reference value at comparator 6. In this way, the water level of the washing machine can be detected electrically and continuously in a high accuracy.

Filed: 1981-05-12
Abstract: PURPOSE:To detect malfunction due to a specific combination efficiently by testing operation by varying the electric specification, address, input and output data constitution, or physical condition of an element to be tested asynchronously and respectively. CONSTITUTION:The constant-output signal L of a noise generator 15 contains frequency components from 0-infinity  and its contents vary partially at random, so comparators 16 and 16a compare the signal L with voltages with optional threshold levels VM and VN, thereby obtaining irregular outputs M0 and N0.

Filed: 1979-06-07
Abstract: PURPOSE:To make an output current variable by providing the method of generating a bias voltage for an output transistor at the drain of IGFET and the method of switching the gate of the output transistor between the bias voltage and the earth potential. CONSTITUTION:When the input terminal of I1 is held at a high level and the input terminals of I2 and I3 are both at a low level, insulating-gate fieled effect transistor IGFETE15 conducts and IGFETE16 becomes unconductive to hold the gate of IGFETE12 at the same potential as that at node 12, allowing IGFETE12 to conduct. At this time, IGFETE13 and E14 are unconductive being grounded at the gates, so that a reference current to flow FETE12 will flow to output terminal 6. Next, when I1 and I3 are at the low level and I2 is at the high level, FETE13 conducts and FETE12 and E14 become unconductive, so that a current twice the reference current will flow to terminal 6. Similarly, changing combinations of input levels of I1, I2 and I3 obtains combinations of output currents as many as 2<3> including when the output current is zero, so that the three-bit current output type D/A converter can be obtained.
