Title: Harmful exhaust gas restraining device for two-cycle engine
Inventor: MATSUZAKA AKIRA
IPC: F02B75/02
Filed: 1989-04-04
Abstract: PURPOSE:To restrain the blowby of mixture, and also to enable the recombustion of unburned gas and incomplete combustion gas by providing both a throttle valve mechanism for narrowing the flow passage at the time of engine low speed and an exhaust gas combustion device, to the exhaust gas passage. CONSTITUTION:The combustion exhaust gas exhausted from a two-cycle engine in the exhaust or intake strokes passes through an exhaust pipe 3, and is discharged into the atmosphere via an exhaust pressure reducing device 4, a harmful exhaust gas retaining device 5 (not shown) and a muffler. And the harmful exhaust gas restraining device 5 is made up of a throttle valve mechanism 7 and an exhaust gas combustion device 8. When the engine speed is low, the valve 11 of the throttle valve mechanism 7 throttles the flow passage (A) so as to have a fairly smaller area than the cross-sectional area of the exhaust pipe 3, so that the exhaust pressure is raised to prevent new mixture from staightly flowing out through the exhaust pipe 3. And the greater part of the exhaust gas concentratedly flowed in the narrow flow passage (A) is brought into contact with the heater 18 of the exhaust gas combustion device 8 to accelerate oxidative combustion.

Abstract: PURPOSE:To prevent rising of temperature at 4 part of a hollow pipe by a method wherein the hollow pipe is formed in a spiral whose curvature radius is changed continuously and the spiral pipe is interposed in a way that its center, line may coincide substantially with that passage. CONSTITUTION:A heat exchanging chamber 2 and a fan 21 are arranged in a body 1. In the heat exchanging chamber 2, a hollow pipe 3 formed in a spiral whose curvature radius is reduced continuously from the downward to the upward is provided in a way that a center line of the spiral pipe 3 coincides substantially with that of the heat exchanging chamber 2, and the both ends of the hollow pipe 2 protrude outside the heat exchanging chamber 2.

By this, the heat transmission rate of the hollow pipe 3 does not increase or decrease depending on parts, whereby the hollow pipe 3 can be heated even. In addition, the hollow pipe 3 does not pile part on part with respect to an airstream, and therefore, can be heated or cooled uniformly. Thus the hollow pipe 3 can be prevented from being heated too high at a particular part.

Title: Steering device for vehicle
Inventor: TSUBOTA YASUMASA
IPC: B62D1/04
Filed: 1994-04-25
Abstract: PURPOSE:To suppress and prevent a one side drift, which is caused by a cant arranged on a road face in straight travel, of a vehicle. CONSTITUTION:For canceling rotational torque of a steering wheel appearing in normal straight travel due to a road face cant, weights 2a, 2b are installed in the steering wheel 1 so that the center point G of gravity of the whole of the steering wheel 1 system is deviated from the center O of rotation by the predetermined quantity. As a result, the moment of rotation is generated by gravity acceleration working on the center point G of gravity against the moment of inertia around the center O of rotation of the steering wheel 1, and the moment of rotation is directed in the reverse direction as well as the rotational torque due to the road face cant, and consequently, a one side drift of a vehicle is suppressed and prevented.

Abstract: PURPOSE:To distinguish the disconnection of the shielded portion of a shielded line from ground by a simple and economical circuit by connecting photocouplers to both the ends of the shielded portion of the shielded line via resistors and making a monitor current flow. CONSTITUTION:DC power supplies 20 and 21 are connected to each other in series, the DC power supply 20 is grounded at one end and one end of the DC power supply 21 is connected to one end of the shielded portion of a shielded line 11 via a resistor 21, a photocoupler 23 and a resistor 25. On the other hand, the other end of the DC power supply 20 is connected to the other end of the shielded portion via a resistor 26, a photocoupler 27 and a resistor 29. The phototransistors (PTr) 33 and 37 of the photocouplers 23 and 27 are con nected to a power supply of +V via resistors 34 and 38, respectively. When the shielded line is normal, the output voltages (e) and (f) of the PTr's 33 and 37 are '0' and '1', respectively, however, when the shielded portion is broken down, the current of the photocoupler 23 is reduced to zero and its output (e) is changed from '0' to '1'. Since current flows in the photocoupler 27 when the shielded portion is grounded, the output (e) of the PTr 37 is changed from '1' to '0' and failure contents can be discriminated.

Title: Video signal processing method and apparatus
Inventor: JIYON ORIBAA RAIAN
IPC: H04N5/91
Filed: 1986-04-17
Abstract: A video signal is modified so that a television receiver will still provide a normal color picture from the modified video signal while a videotape recording of the modified video signal produces generally unacceptable pictures. This invention relies on the fact that typical videocassette recorder automatic gain control systems cannot distinguish between the normal sync pulses (including equalizing or broad pulses) of a conventional video signal and added pseudo-sync pulses. Pseudo-sync pulses are defined here as any other pulses which extend down to a normal sync tip level and which have a duration of at least 0.5 microseconds. A plurality of such pseudo-sync pulses is added to the conventional video signal during the vertical blanking interval, and each of such pseudo-sync pulses is followed by a positive pulse of suitable amplitude and duration. As a result, the automatic gain control system in a videotape recorder will make a false measurement of video level which causes an improper recording of the video signal. The result is unacceptable picture quality during playback. This approach utilizes positive-going pulses which occur at a time not ordinarily used for black-level restoration in typical television receivers, and therefore does not give rise to black level depression in such typical television sets.

Title: Method and apparatus for washing of ion exchange resin
Inventor: HAGIWARA MASAHIRO
IPC: G21F9/12
Filed: 1979-07-10
Abstract: PURPOSE: To effectively wash the resins while decreasing the amount of the waste liquid after the  treatment by supplying ion exchange resins together with water flow into regenerating towers  which have beforehand been supplied with water up to near the free board drain pipe and discharging the clad-contg. waste liquid from the drain pipe.   
     CONSTITUTION: The contaminated ion exchange resins are admitted together with water flow  through a pipe 4 into the 1st regenerating tower 1 which has beforehand been supplied with water  up to slightly above a free board drain pipe 2 to be formed with the water layer shown by a water  level 15 and the waste liquid containing clad portions is discharged from a drain pipe 2. Thence,  when the amount of the resins sedimented on the tower bottom reaches the level of about 30W 35cm below the drain pipe 2, the supplying of the resins is suspended. Air is then press-fed from a  pipe 8 into the tower 1 to perform scrubbing, thereby allowing the clad portions deposited on the  resins to desorb into the water. Thence, a resin discharge pipe 5 and a lead-in pipe 4' are communicated and the clad-portion-contg. waste liquid and the resins in the 1st regenerating tower 1  are transferred into the 2nd regenerating tower 1' which has beforehand been supplied with water  in the same manner as for the tower 1. The same operations having been made in the tower 1 are  then continued.
