Title: Drawing apparatus for optical fiber
Inventor: SAKAGUCHI SHIGEKI
IPC: C03B37/027
Filed: 1981-05-29
Abstract: PURPOSE:To continuously measure the tension of a drawn optical fiber all over by attaching a tension detector detecting the tension by a photoelastic effect in a noncontact state to an apparatus for softening glass for an optical fiber in the heating furnace and for drawing it. CONSTITUTION:A base material 1 is gradually fed into a drawing furnace 3 with a base material feeder 2 and softened by heating. The diameter of the material 1 is made smaller, and the material 1 is continuously drawn into an optical fiber 4 with a capstan 7. At this time, the outside diameter of the fiber 4 is measured with an outside diameter measuring device 5, and the tension is detected with a tension detector 6 between the furnace 3 and the capstan 7 or a drum 8. For example, light from a light source 9 using He-Ne laser is converted into circularly polarized light by a polarizer 10, passed through a quarter- wave plate 11, converged by a lens 12, and passed through the center of the fiber 4. Since the passed light undergoes double refraction according to tension applied to the fiber 4, the tension of the fiber 4 is detected with an analyzer 13 and a photodetector 14. Thus, an optical fiber of high strength can be manufactured.

Title: Water quantity control device
Inventor: KIMURA YOICHI
IPC: F24H1/10
Filed: 1988-04-01
Abstract: PURPOSE:To reduce the whole size of a water quantity control device including a tank, by providing an electric control means which drives a motor-operated valve so that a water level in the tank may be set at a specified water level which is detectable by a water level detecting device. CONSTITUTION:When a motor-operated valve 10 is opened by an electric control means 12, water flows into a tank 8 in proportion to the opening of the valve 10 and the water pressure. The opening of the motor-operated valve 10 is opened by specified degree until the water level reaches a specified water level A, monitoring the water level with a water level detecting means 9. When the water level reaches another specified water level B, the water level detecting means 9 detects the level B. The water level in the tank 8 is stabilized between the water level A and the water level B by closing the opening of the motor-operated valve 10 by a specified quantity so that the quantity of the water flowing into the tank may be equal to that of the water transferred out by a pump 11. In this manner, the water level in the tank can be detected, thereby controlling the quantity of water flowing into the tank with the motor-operated valve so that the quantity of the water transferred out by the pump may be equal to that of the water flowing into the tank. It is, therefore, possible to eliminate the application of a float and minimize the size of the whole device including the tank.

Filed: 1989-03-31
Abstract: PURPOSE:To shorten shift lag and enhance the accelerating characteristic by engaging an engine brake friction element for generation of engine brake at the time of stamping down-shift associate with increase in the degree of throttle opening. CONSTITUTION:At the time of stamping down-shift with the throttle opening increased by an automatic transmission of car, wherein an engine brake friction (c) for generation of engine brake is arranged in parallel with an one-way clutch (b), this is sensed by a stamping down-shift sensing means (d), and the engine brake friction element (c) is engaged through an engine brake engaging means (e). This causes direct coupling of the input side with output side to permit the revolution on the drive wheels to be fed to the power motive (a), so that its rise of revolutions is accelerated by revolutions on the drive wheel side to allow quick attainment of the revolutions on the drive wheel side, and thus down-shaft is completed quickly. Thus shift 18 lag is shortened greatly to accomplish enhancement of accelerating characteristic.
