Abstract: PURPOSE:To improve a rate of fuel consumption as well as to reduce an engine noise, by taking in each detected pressure of a rotation sensor and a load sensor and installing a controller which adjusts the opening of a damping delivery valve, in case of a fuel injection device provided with the damping delivery valve. CONSTITUTION:Damping delivery valve 23 is installed in a delivery valve holder 19 of a fuel injection pump 18. A rotation sensor 28 detects an engine speed, while a load sensor 29 detects engine load. Taking in each detected output of each of sensors 28 and 29, there is provided with a controller 25 adjusting the opening of the damping delivery valve 23 according to engine speed and load. The opening of the damping delivery valve 23 is made to be larger at low and medium speed ranges and at a low injection quantity range. Thus, a rate of fuel consumption is improvable over the whole speed range of an engine and, what is more, an engine noise is reducible.

IPC: G05D9/12
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To continuously measure a liquid level in a measurement container without being affected by the property of an object to be measured by continuously measuring temperature distribution in the measurement container using an optical fiber thermometer where the Raman scattering effect is applied. SOLUTION: An optical fiber thermometer 1 where the Raman effect of an optical fiber has been applied applies a high-speed light pulse to an optical fiber 8 and separates scattering light being reflected from each point of the optical fiber 8 into low-frequency and high-frequency components by a frequency separation circuit 2. One of them is related to the physical properties of the optical fiber 8, while the other is related to the physical properties and a reflection surface temperature. Therefore, the temperature of the reflection surface can be measured according to the ratio of the strength of the two frequency components by a frequency component strength ratio operation circuit 3.  A temperature operation circuit 4 calculates the temperature of each point in a measurement container 7 according to a temperature signal that is outputted by the frequency component strength ratio operation circuit 3. Then, a liquid level measurement circuit 5 converts the temperature of each point being outputted by the temperature operation circuit 4 to calculate a liquid level.

Title: S-z twisting method for optical fiber cable and s-z twisting jig for optical fiber cable
Inventor: OSHIMA MUNEAKI
IPC: G02B6/44
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent the dislodgment of coated optical fibers and the degradation in the transmission loss of the coated fibers after twisting by inserting coated optical fiber ribbons into slots so as to come into contact with the rear surfaces of the slots with respect to the progressing direction of the slots. SOLUTION: A slot inversion detecting section 9 is formed to a cylindrical shape and an S-Z slot rod 1 travels therein. A jig body 4 successively disposed in the slot inversion detecting section 9 inverts simultaneously as well when the slot inversion detecting section 9 inverts. The front end of the guide pipe 5 moves along the inside wall of the slots 2 in the slots 2 and the twisted coated optical fiber ribbons are also successively twisted along the inside walls of the slots 2. Namely, the coated optical fiber ribbons are inserted into the slots 2 so as to come into contact with the rear surfaces of the slots in the progressing direction of the slots 2. As a result, the supply tension of the coated optical fiber ribbons is not only received at the peak parts alone of the slot inversion but is received in a large range as well and, therefore, the burden acting on the coated fibers is made smaller.

Title: Automatic paper selecting method for copying machine
Inventor: SAKATA SEIJI
IPC: G03G21/00
Filed: 1988-11-09
Abstract: PURPOSE:To automatically control the copying machine according to the set condition of a document by inhibiting a copying action when a prescribed-sized feeding cassette is not set and a copying action is finished because papers run short. CONSTITUTION:OR is found between a hard reset signal and the ready signal of a CPU, and the copying machine is controlled to reset by this OR output (a soft reset signal). Besides, even when there is no paper in the feeding cassette selected at the time of automatic paper selecting (APS), a print switch is controlled to print. Meanwhile, when a document size detection detects that any prescribed papers are not set at an automatic document feeding device (ADF), the print switch is inhibited to print. Besides, when the copying action is finished during copying because papers run short, copying action is also controlled to inhibite. Thus, in which CPU an error arises at the time of resetting can be easily found, and the action of the ADF can be controlled according to the set number of documents.

Abstract: PROBLEM TO BE SOLVED: To prevent reduction in quality of woven fabric by lessening response delay of detection of warp end breakage and suppressing advance of weaving in a state of warp end breakage as it is in detecting the warp end breakage by taking advantage of grasp of warp end breakage by a brush roller. SOLUTION: A brush roller 1 is rotatably installed with facing to a warp line and the brush roller 1 is positively rotated and driven in the direction of the warp line so as to bring the tip of brushes 16 into contact with the warp line.
