Title: Running speed change control device of running machine for work
Inventor: NAGATA FUMIHIKO
IPC: F16H59/70
Filed: 1988-09-12
Abstract: PURPOSE:To carry out a rapid running speed change responding to the gear shift operation by detecting the gear shift operation speed of a gear shift device, and providing a gear shift step control device to output a gear shift control instruction to jump over intermediate steps largely as it is at the higher gear shift side, in a high speed gear shift operation. CONSTITUTION:When the operation of a gear shift lever 3 is detected by the operational condition of a controller 5 from the variation of the detecting value of a lever angle detecting sensor 4, the lever variation amount is computed together with deciding whether the variation is at the increasing speed side or at the decreasing speed side. It is detected whether the variation amount is smaller or larger than a preset variation value, and when it is decided smaller, the following gear shift step is computed by converting one step to the higher speed side or to the lower speed side to the preset gear shift step, and the speed change is controlled into the responding gear shift speed depending on the resultant gear shift step. And it is judged whether the increased or the decreased speed is equal to the lever set value or not, and when it is not equal, the variation value is controlled one step more in the higher or lower side. The speed change is controlled step by step in such a way to make the running speed equal to the running speed at the gear shift step set by the shift lever.

Then, when the voltage of the main battery 13a is lowered to be near a reset voltage, changeover is automatically performed to the auxiliary battery 13b. Also, when the main battery 13a is exchanged to a new battery, and the voltage of the main battery 13a is restored to the normal value, the changeover from the auxiliary battery 13b to the main battery 13a is automatically performed. An electrolytic capacitor 15 performs the role of an auxiliary power source when the main battery 13a or the auxiliary batter 13b is instantaneously cut off from the power source line of a circuit when the electronic switch 17 is switched.

Abstract: PURPOSE:To facilitate the working between the magnetic poles of a quadrupole electromagnet by forming the good magnetic field regions of the quadrupole electromagnet in such a manner that said regions are nearly proportional to the max. outside shape of the moving range of a charged particle beam. CONSTITUTION:Working accuracy is partly reoughened in such a manner that the magnetic field accuracy of the regions which are entirely unnecessary for experiment of the charged particle beam is lowered. Namely, the working accuracy of one region RNG1 of the magnetic pole face 11A facing the minor axis side of the beam moving range 22 is roughened to roughen said face and the working accuracy is made higher in the part of the other region RNG2 adjacent to the region RNG1 than the section of the region RNG1. The good magnetic field region 21A of the quadrupole electromagnet is worked by such working to the circular shape nearly proportional to the sectional shape of the beam moving range 22 as shown in the figure (b) and the part of the magnetic pole surface to be worked with the high accuracy in conformity with the sectional shape of the beam is minimized.

Filed: 1994-08-29
Abstract: PURPOSE: To make manufacturing and recycling easy, to eliminate electrifying noise, interference fringes and soiling on a body to be electrified and also to form an image of high quality for a long time with reduced environmental fluctuation. CONSTITUTION: A non-contact electrifying member 2 is constituted by attaching a second resistant layer 22 to an aluminum substrate 20 through an insulating material 23, and a first resistant layer 21 below the material 23. The electrifying surface 21a of the layer 21 is opposed to the surface 1a to be electrified on the photoreceptive drum 1. A superposed voltage is impressed on the layer 21, and an AC voltage or a DC voltage is impressed on the layer 22. Thus, the layer 22 is heated, so that the temperature of the layer 21 rises. Relative humidity in the atmospheric gas falls, so that moisture absorbing of the layer 21 and that of fine toner and paper powder sticking to the surface of the layer 21 are prevented. The resistant irregularity on the surface of the layer 21 is eliminated, so that the uniform electrification can be always performed under any environment.

Abstract: PURPOSE:To changeover a feeding path without feeding a feeding path causing a host switching with respect to the feeding system for the submarine transmission system in which three land stations or over are interconnected through one submarine branching device or over and they are communicated together. CONSTITUTION:On the occurrence of a fault, a sound wave signal generating means 2 sends a sound wave control signal to a submarine branching device 1 with information from a land station (not shown in figure). The sound wave control signal propagates under sea and then the sound wave signal generating means 2 is installed under sea or on sea in the vicinity of the submarine branching device 1. Thus, the sound wave control signal propagated through sea from the sound wave signal generating means 2 in this way is received by a receiver 3 of the submarine branching device 1 and the receiver extracts the sound wave control signal and gives it to a control circuit 4. Then the control circuit 4 controls a relay device 5 based on the control signal to apply changeover control the feeding path to the land station or the submarine branching device 1. However, the feeding from the land station to each submarine branching device 1 is interrupted at the changeover control.
