Title: Preferential transmission method for high-traffic circuit
Inventor: SATO YASUHARU
IPC: H04L29/06
Filed: 1988-04-01
Abstract: PURPOSE:To early transmit a specific message by sending a transmission inhibiting request to a transmitting circuit driver to inhibit the transmission of other ordinary messages in the case a receiving circuit driver receives a specific message. CONSTITUTION:When a specific message is received from a circuit LA, a receiving circuit driver 5 sends first a transmission inhibiting request to a transmitting circuit driver 9. Thus the driver 9 inhibits the transmission of the ordinary messages. Then the driver 5 sends the end information for reception of the specific message to a specific message processing task 8. The task 8 edits the received specific message into a transmission specifying message and requests the driver 9 to transmit the specific message. When a transmission request is received from the task 8, the specific message is immediately transmitted if no time-out state is kept. Thus the transmission of the specific message is accelerated.

Title: Turbidity measuring instrument
Inventor: YOSHIKAWA TAKASHI
IPC: G01N21/49
Filed: 1979-06-26
Abstract: PURPOSE:To provide a turbidity measuring instrument of reduced dimensions and weight, by utilizing the refractive index of a solution to be measured, providing spherical glass at an exit of a light emitting section and an entrance of a light receiving section of the instrument, and using as a lens a vessel containing the mentioned solution to save a lens. CONSTITUTION:Rays of light from a light source 4 in a light emitting section 1 are concentrated at a pinhole 6 via a condenser 5. The rays of light coming out of the pinhole 6 are rendered parallel to one another by a collimator lens 7. These parallel rays advance through an exit glass 8 to enter a solution 2 to be measured. Since the glass 8 is made spherical, the parallel rays are condensed at an intermediate point A in the solution 2. When the solution is not turbid, the rays condensed at the point A diverge again to advance through an entrance glass 8 in a light receiving section to be rendered parallel to one another again. These parallel rays enter a light receiving element 10 via a lens 9. When the solution 2 is turbid, scattered rays of light at the point A advance through the glass 8 to be rendered parallel. The parallel rays enter a light receiving element 11 provided in a focus F o f the lens 9. The turbidity of the solution can be determined with reference to a ratio of outputs from the light receiving elements.

An overvoltage detecting circuit 2 detects the output voltage of the full-wave rectifying circuit 1 and compares the output voltage with a permissible reference value and, when the output voltage exceeds the reference value, outputs a signal to a thyristor gate. A thyristor 4 is switched by means of an output signal from the detecting circuit 2 and the output voltage of the rectifying circuit 1 is made to be consumed by a resistance. By means of this circuit, the thyristor 4 is ignited by means of the voltage rise of a regenerative current absorbing circuit A and the resistance 3 is made to consume a regenerative energy and, as a result, impression of an overvoltage upon a GTO is prevented, when bad contact occurs in main contactors CTTU, CTTV, and CTTW at the time of regenerative braking of a motor.

Title: Ripple eliminating circuit
Inventor: AOKI MINORU
IPC: H03D1/06
Filed: 1979-06-28
Abstract: PURPOSE:To realize the elimination for only the ripple component caused by the carrier without impairing the effective alternating current in the input signal, by utilizing the forward voltage drop of the diode. CONSTITUTION:The serial circuit of capacitor C and resistance R3 plus diodes D1 and D2 are provided between input terminal 1 of the signal and the inverse input terminal of operational amplifier OPA. At the same time, resistance R1 plus diodes D1 and D2 are provided to the noninverse input terminal. In case the amplitude of the ripple component of the input signal is less than the forward voltage drops of diodes D1-D4, no ripple component occurs in the output signal. And in case the alternating current component which is more than the diode's forward voltage drop is contained in the input signal, diodes D1-D4 are turned on with the ripple component emerging directly at the output. Here the control is given to the gain of the amplifier of the preceding step so that the amplitude of the input signal may be less than the forward voltage drops D1-D4. Thus the ripple can be eliminated.

Filed: 1982-05-17
Abstract: PURPOSE:To prevent malfunction by connecting a lateral TR to a power supply terminal at its emitter and to the base of a TR provided nearby at its collector, and opening the base of said lateral TR. CONSTITUTION:If a (plus) input terminal 5 is held below (-VCC-VBE) while muting is made effective by turning off a switch S, parasitic NPNTRs 12 between TRs Q1, Q3, and Q4, and a TRQ5 turn on respectively, and a parasitic PNPTR is formed between the TRs12 and Q5 and this also turns on similarly.
