Title: Accelerating device for carburettor
Inventor: SUZUKI KENICHI
IPC: F02M7/08
Filed: 1981-03-23
Abstract: PURPOSE:To prevent the blow out of fuel of a fuel passage which occurs upon temperature rise as well as the fluctuation of air to fuel ratio of the carburettor by a method wherein a pressure regulating means, operated in accordance with a pressure, is provided at the fuel passage part of the accelarating device of the carburettor driven by a pumping action. CONSTITUTION:Under the normal operation of an engine, the opening degree of a throttle valve 6 is small and the pressure in a port 7 is low, therefore, a diaphragm 12 is displaced to the right, the volume of a pump chamber 11 is increased to open a non-return valve 17 and the fuel in a float chamber 4 is sucked through a suction side fuel passage 15. Next, when the throttle valve 6 is opened to accelerate the engine, the pressure in the port 7 approaches the atmospheric pressure, the diaphragm 12 is displaced to the left and the volume of the pump chamber 11 is decreased. According to this operation, the fuel in the pump chamber 11 is pressurized and a delivery side non-return valve 18 is opened. In this case, the opening and closing valve 24 of the pressure regulating means 21 is opened once, however, the passage 26 is closed and therefore a fuel discharging passage is closed instantly. When the fuel temperature in the fuel passage is risen up and the pressure thereof is increased during closing of the non-return valves 17, 18, the opening and closing valve 24 of the pressure regulating means 21 opens the passage 25, 26 to decrease the pressure of the fuel.

Filed: 1981-03-23
Abstract: PURPOSE:To float air containers expanded in liquid upward continuously, by  providing a plurality of enclosed and expansible air containers and a pipe communicating the air containers to each other between non-parallel rails erected in the liquid. CONSTITUTION:Rails 3 are not parallel to each other, and each of air containers 1 is made of a cylindrical, fabric-reinforced rubber, helical spring, circular metal, etc. When an expanded air container 1 is contracted, superfluous air in the container 1 is transferred to other air container 1 being expanded through a pipe 5 which is extended through the air containers 1 in the manner of communicating them to each other. When water is charged fully into a water container 2, the differential volume of an expanded air container and a contracted air container is converted into buoyancy, so that energy is produced in the direction of buoyancy. Here, air container 1 having lost buoyancy is contracted, immersed deep into the water, and then returns to its original position. In the drawing, the water container is shown in its cross section. However, as viewed from the side of a cover 6, the rails 3 are observed in the form of ?-shape.

Title: Motional feedback system
Inventor: IKEDA MASATO
IPC: H04R3/04
Filed: 1981-03-26
Abstract: PURPOSE:To enable to apply motional feedback optimum to a many kinds of speakers, by automatically selecting a dynamic impedance to be used and controlling a variable impedance of a bridge. CONSTITUTION:When a switch S1 turns off and S2 and S3 turn on, an oscillation circuit O outputs a signal with the same frequency as a low frequency resonance frequency f0 of a speaker. The phase difference between an oscillation output of the oscillation circuit O and a terminal voltage of a variable impedance element VT is detected at a phase comparison circuit PH to change  the impedance of the variable impedance element VT until the phase difference  becomes zero. Thereafter, the value of the VT is stored in a digital memory DM via switch S4. Thus, when the switch S1 turns on, and the S2 and S3 turn  off, since an MFB signal is supplied via an MFB amplifier OP according to the  set value of the VT, the MFB circuit suited to the impedance characteristics of  a speaker to be used can be obtained.

Title: Inverter
Inventor: NAKAMURA SHIGEO
IPC: H02M7/48
Filed: 1989-02-23
Abstract: PURPOSE:To prevent an excess rush current and to early establish the output of an inverter by conducting a shortcircuiting operation of a rush current preventive resistor between a rectifier and a transformer only when a potential difference between both ends of the resistor becomes a predetermined value or below. CONSTITUTION:A rush current flowing when a power source is turned ON is suppressed by a current limiting resistor R1. When an inverter starts operating, a voltage generated in an auxiliary winding 3 is rectified by a rectifier D1 to tend to turn ON a thyristor S, but a large potential difference at both ends of the resistor R1 is divided by resistors R2 and R3 to turn ON a transistor TrQ1, the gate of the thyristor S is grounded to eliminate the operation of the thyristor S. When the operation of the inverter is advanced and the voltage of a capacitor C is raised to a predetermined value, the TrQ1 is turned OFF, the thyristor S is turned ON, and the resistor R1 is short-circuited. Thus, an excess rush current can be prevented by a simple circuit, and the output of the inverter can be early established.
