Title: Constant-speed traveling apparatus for car
Inventor: TANIGAWA MITSUARI
IPC: B60W30/14
Filed: 1981-12-26
Abstract: PURPOSE:To prevent abnormal rise of the number of revolution of an engine by installing a release prohibitting circuit which prohibits release of overdive when the car speed becomes high and continues said prohibition unitil the car-speed lowers to a prescribed value. CONSTITUTION:The differential voltage between a set-speed voltage 3 and a car- speed voltage 1 is output from a subtraction circuit 2. An autodrive control- circuit 4 controls the opening of a throttle etc. and controls traveling at a set speed. As the output of a flip-flop 15 is ''0'', when a car travels at a high speed, an overdrive cutting solenoid 9 is not excited, and release of overdrive is prohibited. As the reset output of the flip-flop 15 becomes ''1'' when the car-speed reduces below a prescribed value, the overdrive cutting solenoid 9 is excited and switching from the fourth-speed to the third-speed is performed, when a flip- flop 7 is set. Thus, abnormal high-speed revolution can be prevented.

Filed: 1990-08-15
Abstract: PURPOSE:To improve the operating rate of a DC arc furnace remarkably, eliminate the danger of leaking of molten steel to the outside of the main body of the arc furnace and improve safety upon operation remarkably by a method wherein an anode, mounted on the hearth of the main body of the arc furnace and having fear to cause damage by melting, is eliminated and the anode is inserted into the main body of the arc furnace from the upper part thereof together with a cathode. CONSTITUTION:Scrap 35 is charged into the main body 1 of an arc furnace at first and an arc 36 is produced between the scrap 35 and the lower end of a cathode 7 whereby the scrap 35 is molten and molten steel 37 is obtained. When the molten steel 37 begins to be reserved on the hearth of the main body 1 of the arc furnace, an anode 12 is operated through elevation so that the lower end of the anode 12 is dipped into the molten steel 37, then, the cathode 7 is operated through elevation so as to retain the arc 35 by following the upper side position of the scrap 35 lowered as the advance of the melting of the scrap 35. When the scrap 35 is molten perfectly substantially, the cathode 7 is operated through elevation so that a distance to the level of the molten steel 37 is regulated. In this case, an electromagnetic force is effected in the arc toward the outer peripheral direction of the same by a current conducted from the lower end of a cathode 7 toward the lower end of the anode 12 and the arc is bent into the outer peripheral direction whereby uniform arc is generated in the circumference of the lower end of the cathode 7.

IPC: G02B6/293
Filed: 1987-08-28
Abstract: PURPOSE:To reduce a variation of a loss when a small parallel movement is generated in an optical filter and a parallelogrammatic prism, by using the parallelogrammatic prism in which an optical filter for allowing a light beam of a specific wavelength area to transmit through or reflecting it is formed or fixed closely on at least one surface. CONSTITUTION:A light beam of a specific wavelength area lambda1 transmits through an optical filter 15, transmits through a lass block 17, and thereafter, converged by a lens 14a and made incident on an optical fiber 12a. On the other hand, a light beam of the other wavelength lambda2 is reflected by the optical filter 15, and also, reflected by the surface of a parallelogrammatic prism 16, and thereafter, converged by a lens 14b and made incident on an optical fiber 12b. That is, when a small parallel movement has been generated in the optical filter 15, the parallelogrammatic prism 16 and the glass block 17, a shift of an optical axis in the parallelogrammatic prism 16 is generated, but at the outside of the parallelogrammatic prism 16, the shift of the optical axis is not generated.

Furthermore, since the exhaust gases emitted from the rear cylinders flow from the left and right inner pipes 70 and 90 through respective small holes 75, 76... and 95, 96... into the collector chamber 50, the torque in high engine speed range can be made the same as a front cylinder. Consequently, the smooth increase in torque in the engine speed range ranging from low speed range to medium speed range can be realized and at the same time the torque in engine high speed range can be ensured.
