IPC: B60K25/00
Filed: 1983-07-29
Abstract: PURPOSE:To suppress noise and vibration of an engine and improve its fuel consumption, by decreasing a control distance smaller than the control distance of a throttle lever by a predetermined amount through a rod movably contained in a solenoid so as to reduce an output of the engine when a speed change gear is shifted to its high speed side under the no-work condition of a machine. CONSTITUTION:One end of a rod 12 is pivotally mounted to a throttle adjusting arm 11 of a carburetor, and the other end of the rod is connected to a solenoid operating structure 13. The operating structure 13 is a predetermined distance movably contained in a solenoid 14, and a protruding length of the structure 13 is changed decreasing when the solenoid 14 is excited or increasing when it is not excited. A switch 17 in the three-speed position of a speed change shift 9 is turned off only when a speed change lever 7 is shifted to the three-speed position, releasing excitation of the solenoid 14, and the operating structure 13 protrudes from the solenoid 14 returning a position of the arm 11 in its operating range to the position B from the position A to which the arm 11 has been moved when the solenoid is excited. In this way, a running speed is also controlled to within the specified limit by decreasing an engine output.

Title: Radio-wave lens element
Inventor: SATOU SHINICHI
IPC: H01Q15/02
Filed: 1977-11-22
Abstract: PURPOSE:To make it possible to form a radio-wave lens element with phase variation from 180 deg. to 360 deg. of a phase shifter of 0 deg. to 180 deg., by feeding a reception antenna and radiation antenna from mutually-opposite directions in regard to a straight line connecting both feeding points. CONSTITUTION:In regard to straight line 10 connecting feeding points 9, reception antenna 5 and radiation antenna 6 are fed from mutually-opposite directions. Radio waves with linear polarized waves arriving at the radio-wave lens element in this constitution are supplied to macrostripe line 1 via horn 4, slot line 3 and feeding points 9 and reach antenna 6 through phase shifter 7, so that they will be radiated from horn 4 in the air. Since the direction of polarized waves of radio waves radiated from this antenna 6 is different from the conventional ones, the radio-wave lens element 180 deg. out of phase with the conventional ones can be obtained. This results in that the radio-wave lens element with phase variation from 180 deg. to 360 deg. can be formed of phase shifter 7 of 0 deg. to 180 deg., so that the loss at phase shifter 7 can be reduced to half in comparison with the conventional ones.

     CONSTITUTION: A first and second O 2  sensor 5, 6 are installed to an exhaust passage from an internal combustion engine 1 to a ternary catalyzer 4, and a temperature of the ternary catalyzer 4 is detected by a temperature sensor 8. On the basis of the above sensors' outputs, an air bleed actuator 3 and air pump 7 are controlled through an electronic controller 9. In this way, during at low temperature detected by the temperature sensor 8, a fuel supply quantity is increased through an air quantity reduction of the air bleed actuator 3, simultaneously with an air quantity increased of the air pump 7, and with the detected temperature getting high, an air quantity of the air bleed actuater 3 is controlled so that a fuel-air ratio detected by the first O 2  sensor 5 may be at a level near the theoretical fuel-air ratio. Further regardless of a level of the detected temperature, an air quantity of the air bleed actuator 3 and the air pump 7 are controlled so that a fuel-air ratio detected by the second O 2  sensor 6 may approximate to the theoretical fuel-air ratio.

Filed: 1989-06-05
Abstract: PURPOSE:To prevent production of color blurring at a color border by detecting a luminance signal level and controlling noise reduction circuit operation of a color difference signal with an AGC signal outputting a high/low level. CONSTITUTION:The GAIN of a luminance signal 13 is varied depending on a level of an AGC signal 15 resulting from a luminance signal 14 passing through the AGC circuit 6 detected by a detection circuit 4. Then the luminance signal 14 is fed to an encoder circuit 3. A switching circuit 2 uses a level of the AGC signal 15 from the detection circuit 4 to switch a color difference signal 8 not through a noise reduction circuit 1 and a color difference signal 9 through the noise reduction circuit 1 and the result is supplied to the encoder circuit 8 as a color difference signal 10. The encoder circuit 3 uses the color difference signal 10 and the luminance signal 14 to output the video signal 12. when the AGC signal 16 is reset, since the color difference signal 8 not passing through the noise reduction 1 is outputted, no vertical false signal is generated. When the AGC signal 15 is set, since the color difference signal 9 passing through the noise reduction circuit 1 is outputted, the color S/N is improved.

Title: Method for measuring liquid chemical
Inventor: TAKIGAWA MASAO
IPC: G01F11/12
Filed: 1985-06-29
Abstract: PURPOSE:To eliminate the error by an operator and to always uniformly and precisely introduce a liquid chemical into a measuring tank by controlling the opening degree of a valve provided to an introducing route to meet the increase in the amt. of the liquid chemical to be introduced thereby regulating the inflow rate into the measuring tank. CONSTITUTION:The height of a liquid level in the measuring tank 4 is kept detected at all times by an ultrasonic oscillator 5 provided to the upper part of the tank. A control part 17 calculates the volume of the liquid chemical introduced into the tank 4 from the height of the liquid level in accordance with the signal from the oscillator 5 when a factor to determine the required amt. of the liquid chemical is inputted thereto. The control part 17 changes the opening degree of a supply valve 10 at all times to meet the amt. of the liquid chemical which is actually supplied with respect to the required amt. of the liquid chemical. For example, the opening degree of the valve 10 provided to a piping 11 from a stock tank 1 is automatically adjusted to 20% when the supply rate of the liquid chemical attains 80%. The opening degree is adjusted to 0% at 100% supply rate. The measurement error is minimized by controlling the introducing rate of the liquid chemical in the above-mentioned manner.

Abstract: PURPOSE:To decide on the improvement state of a ground improved part in the ground by a ground improving method by taking measurement by utilizing a boring hole digged in an unimproved ground of the ground improved part by an acoustic reflecting method. CONSTITUTION:A rod 4 is inserted into the digged hole of the unimproved ground E outside and near the ground improved part E1. An acoustic wave transmitter 5 and a receiver 6 are inserted into the rod 4 rotatably; and the transmitter 5 transmits a wave P1 toward the improved part E1 and its reflected wave P2 from the boundary surface between the external edge of the improved part E1 and ground E is received by the receiver 6, thereby measuring the distance (d) from the rod 4 to the external edge of the improved part E1 from the time difference between the transmission time of the transmitted wave P1 and the reception time of the reflected wave P2. In this case, noise pulses are received, but only pulses larger then a constant threshold value are detected as the reflected wave P2 to eliminate malfunction due to noise pulses. Further, the intensity of the reflected wave P2 is used to decide on the hardness of the improved part E1, i.e. improvement state of the improved part E1. The transmitter 5 and receiver 6, on the otherhand, are measured at the position of the rod 4 to decide on the shape of the improved part E1.
