Abstract: PURPOSE: To independently discharge two ignition plugs by a single ignition coil by preventing the loss of ignition energy and the deterioration of the energy accumulating effect of the ignition coil, and also to achieve unification of discharge polarities. CONSTITUTION: When an ignition signal (a) is turned on, transistors TR5, TR1, TR4 are turned on, and primary current is allowed to flow to a primary coil of an ignition coil 3 in the direction shown by the solid line, on the other hand, when the ignition signal (a) is turned off, the transistors TR5, TR1, R4 are turned off, and high-pressure counter electromotive force is generated on a secondary coil. At this time, electric discharge of the minus polarity is generated on an ignition plug 4b, discharged secondary current is returned to the ground contact side through a high-pressure diode D1, and an ignition coil 4a is not discharged. The ignition plug 4a is discharged in the minus polarity by an ignition signal (b) contrary to the case of the ignition signal (a), and the ignition plug 4b is not discharged. Therefore, energy is effectively accumulated on the whole primary coil, respective ignition plugs 4a, 4b are independently discharged, and the loss of ignition energy is prevented.

IPC: G01N3/12
Filed: 1987-04-02
Abstract: PURPOSE:To take an accurate pressure-resistance test by using a guide chip so as to align the centers of a seal chip and the center of the hole surface of a hose joint with each other and also using a pressure application system exclusive for sealing so as to adjust the pushing pressure of each seal chip to proper and uniform pressure. CONSTITUTION:The surface of the guide cap 10 is moved by a cylinder 13 to the hose joint 2 set on a joint supporting base 11 to cover the guide surface 22 of the joint 2. Here, when their centers are not aligned with each other, the cap 10 abuts on the joint 2 and the cylinder 13 stops operating, so that an alarm is generated. Then when the cap surface 10 covers the guide surface 22, the seal chip 9 fitted to a piston 14 is pushed out with high-pressure water for sealing from a high-pressure water supply hole 17 for sealing, so the hole surface 21 of the joint 2 is sealed with the hole surface 31 of the chip 9. This piston 14 is fitted independently to each chip 9, so it advances until prescribed pressure is reached, so that no irregular pushing pressure is obtained. Then the high-pressure water is supplied from a water-proof water supply hole 18 to conduct the pressure-resistance test. Thus, the pressure- resistance test is accurately conducted.

Title: Light communicating system
Inventor: YUGAWA JUNICHI
IPC: H04B10/27
Filed: 1986-04-08
Abstract: PURPOSE:To decrease the number of the terminal of a star coupler and the number of an optical fiber and to simplify a circuit by connecting respective directional couplers to other edge of plural optical fiber transmission lines connected to a reflective type star coupler and connecting a light transmitting circuit and a light receiving circuit to respective directional couplers. CONSTITUTION:A light communicating circuit 1 converts an electrical signal to a light signal and a light receiving circuit 4 converts the light signal to the electric signal. A directional coupler 6 mounts the light output signal of a light transmitting circuit 1 to an optical fiber transmission line and reversely, separates a receiving light signal from the transmission line 5 and sends it to the light receiving circuit 4. When a reflective type star coupler 12 is a light element having plural terminals for the optical fiber and the light signal is inputted from one optical fiber transmission line, the light signal is branched equal to a self-and other optical fiber transmission lines by the internal reflection. Consequently, the light signal sent from one light transmitting circuit 1 is simultaneously received in the light receiving circuit 4 connected to a near- end and other plural optical fiber transmission lines. Consequently, only by assigning one fiber per terminal, the bidirectional transmission can be executed.

Abstract: PURPOSE:To prevent metallic sodium from entering the gap between a cylindrical plug and a small hole plug by forming an annular groove in the inner periphery of the lower end of the cylindrical plug inserted into a small hole for fuel exchange or the outer periphery of the lower end of the small hole plug. CONSTITUTION:Sodium 2 which sticks on the periphery of the lower end of the small hole plug 31 and the annular lock part 32a at the lower end of the cylindrical plug 32 enters the gap 33 between the plugs 31 and 32 during operation from a contact surface 32b for the small hole plug bottom surface part 31a of the lock part 32a by capillarity, but the capillarity is cut by the annular groove 35 formed at the lower end of the plug 32 to prevent the sodium 2 from entering its upper part, thereby reducing the amount of sodium sticking on the gap 33. Further, when fuel is replaced, the plug 31 is pulled out while the temperature is lowered so that the sodium 2 does not vaporize, and then when a fuel charging and discharging machine is installed, the sodium 2 is prevented from sticking on the internal surface of the plug 32; when the plug 31 is inserted again, the sodium 2 and sodium oxide on the internal surface of the plug 32 need not be removed. Then same effect is obtained even when the annular groove 34 is formed in the outer peripheral wall of the plug 31.

Title: Measuring circuit for characteristic of solar battery
Inventor: HIGAKI YUKIO
IPC: G01R31/26
Filed: 1980-06-17
Abstract: PURPOSE:To enable the voltage-current characteristics of a solar battery to be measured efficiently and highly accurately, by employing as a load an active element having a voltage-current characteristic curve which crosses that of the solar battery over an approximately whole region, and having no constant-current region. CONSTITUTION:Between the electrodes of a solar battery S, an ammeter A and a static induction type transistor SIT are connected in series. The voltage value of a power source EG for bias is changed to vary the bias between the source and gate of the SIT, in order to control the drain current, that is, the load current IL with respect to the solar battery. Thus, while the bias is being varied, the load current IL are valued of the load current IL and voltage VL are measured and recorded. In this case, the voltage-current characteristic curve of the SIT crosses that of the solar battery at a sufficiently large angle over an approximately whole region, but has no constant-current region which is parallel to the characteristic curve of the solar battery. Accordingly, employing said SIT as a load permits the voltage-current characteristics of a large-sized solar battery to be measured efficiently and accurately.
