Filed: 1981-10-02
Abstract: PURPOSE:To improve the capacity of an engine for a marine screw by setting an exhaust pipe at the optimum length in accordance with the number of revolutions of the engine. CONSTITUTION:At the low-speed revolution of an engine, a heat-sensing wax 28 is soaked in th water entering and filling a housing 27 from a main opening 19 of an expansion chamber 18. The wax 28 is contracted to keep a valve 24 at a closing position of the second exhaust port 22B, and consequently, the first exhaust port 22A of an exhaust pipe 21 is opened to operate the engine at the prolonged state of the exhaust pipe 21. At the high-speed revolution, the heat- sensing wax 28 is exposed to the exhaust gas of high temperature, and extended to push up a rod 29. Then, the valve 24 is kept to open the second exhaust port 22B and close the first exhaust port 22A, and the exhaust gas is exhausted from the second exhaust port 22B. Thereby, the engine is operated at the shortened state of the exhaust pipe 21.

Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To correctly take up error information and to normally obtain an output result even concerning a divided image by changing the arrangement of plotting instructions in the order of execution in accordance with discrimination with respect to the existence of division, following the rearranged execution order and executing the plotting processing of a corresponding plotting area, in accordance with shared plotting processing information. SOLUTION: When an output request is given (S101), it is converted into a signal of prescribed color information and it is discriminated whether a plotting object is an image object (S102). When it is discriminated to be an image object (S102-Yes), image area information is preserved (S103). When plotting information is discriminated as not being the image object (S102-No), the plotting instruction is preserved as is (S104). The plotting processing is executed through the use of the preserved plotting instruction and image rectangular area information (S106). Therefor, error distribution information required for a binaring processing is shared between the corresponding areas, even when the image object is divided.

While they do not detect signals, a signal corresponding to the difference between the detected rotational speed and a target speed 26 of the drum is supplied to the drum driving means 15. When an unrecorded part of a tape 16 comes, the rotational speed of the drum or the feed speed of the tape 16 controlled in accordance with the detected value of the relative speed is so switched by a switching means 32 that the prescribed drum target speed 26 or a tape target speed 28 is attained. Thus, all information are quickly performed program searching even at the time of reproducing the tape partially including unrecorded parts.

Filed: 1989-06-21
Abstract: PURPOSE:To make execution of work easy by thrust a hollow cylindrical mandrel into weak subsoil with its openable end closed, and by discharging hardenable liquid substance into the subsoil as the mandrel is pulled out with the end opened. CONSTITUTION:A hollow cylindrical mandrel 10 is thrust into weak subsoil E roughly at perpendicular with its openable end closed. While the mandrel 10 is pulled out, a cone 12 attached to the end is detached allowing the end to open, and hardenable liquid substance 14 is injected into the inside. Then the liquid substance is allowed to discharge from the end of the mandrel 10 into the subsoil and a pilelike hardened body 16 is formed after hardening of the liquid substance 14. Injection pressure of the hardening liquid substance 14 is made changeable so that the pressure can be set to become lower in stages in proportion to the decrease of the depth. Thereby proof stress of the ground can be increased.

IPC: B66C13/48
Filed: 1985-07-15
Abstract: PURPOSE:To aim at reduction in the number of warehousemen, by detecting a crane traveling position automatically, while displaying an operation command with a terminal machine and judging it automatically with three-dimensional coordinates through a computer for determination. CONSTITUTION:A computer 1 depicts depository information as every column and stage from an external memory 2 and displays a baling image on a picture while discriminating fullness, space in reserve, room, and the presence of shipping and receiving booking. With this image on the screen, a warehouseman finds an optimum space, while a computer 1 secures as a receiving reservation depository in order of a required space on the basis of the inputted layer- stacking restrictive condition, and stores the reservation and schedule order. At the time of product arrival, information of a crane unit is made out, while on the basis of the storage order made out, a receiving command display is given to a crane mounted station 4. When a crane man makes his crane travel toward a column of the display position, a position detector in the traveling direction operates, making sure of a congruity with the displays between the command column and the existing column, thus operation-end is inputted.

IPC: G02B6/12
Filed: 1984-07-26
Abstract: PURPOSE:To realize the function of an optical comparator by making the phase constant equal by impressing voltage when the width of two potical waveguide parts is different. CONSTITUTION:When input optical signals of both IinA and IinB are 1, voltage is generated at both photovoltaic elements 21, 22 by the lights propagate through optical waveguides 11, 12, and is impressed on both electrodes 31, 32. Therefore, a reference input optical signal IinR propagates through an optical waveguide 13, an output optical signal Iout becomes 1. In case when the input optical signal of IinA is 0 and that of the IinB is 1, the voltage is generated at only the photovoltaic element 22, and this voltage is impressed on the electrodes 32. The reference light IinR is outputted from an optical waveguide 14 by a directional coupler. Therefore, the output optical signal Iout becomes 0. In this way, the function of comparator is realized.
