Title: Phosphor supply device
Inventor: TAKAHASHI SHIGERU
IPC: H01J9/227
Filed: 1985-07-31
Abstract: PURPOSE:To forma phosphor film of stable quality while always supplying a constant amount of phosphor by weighing phosphor to be supplied from the nozzle of an accumulator by means of an electron scale while supplying said weighed phosphor to a panel. CONSTITUTION:Phosphor is supplied from the nozzle 5 of an accumulator 3 to an electron scale 6. When the weighed value of the electron scale 6 reaches the preset value, the electron scale 6 outputs a signal for stopping a driving motor of the accumulator 3 by said signal while stopping supply of the phosphor from the nozzle 5. Subsequently, an air cylinder 9 operates to move the electron scale 6 above a panel 10 followed by operating a high rotor 7 to oscillate the electron scale 6. The phosphor weighed by the electron scale 6 is transferred to the panel 10 and when transfer of the phosphor to the panel 10 is finished, the electron scale 6 restores its former position by an operation opposite to the former. Thereby, a constant amount of the phosphor is always supplied to the panel 10 for forming a phosphor film of stable quality.

Title: Production of optical fiber cable
Inventor: OKI HIROYASU
IPC: G02B6/44
Filed: 1993-07-08
Abstract: PURPOSE:To provide a process for production for stably securing the surplus lengths of optical fibers and for integrally molding the cable having such structure. CONSTITUTION:A take-up surface 14 of a rear stage capstan 12 is inclined to a capstan shaft 13 and, therefore, the position of a tension member 4 of the optical fiber cable is nearer a rear stage capstan shaft 13 than the position of the optical fibers 1. The delivery speed of the optical fibers is, therefore, made higher than the delivery speed of the tension member by a difference in the diameters when the cable moves on the circumference of the rear stage capstan. The surplus length is imparted to the optical fibers when the optical fibers are integrated to the optical fiber cable in this state. A tube forming mouthpiece 15 of an extruder head, in which the optical fibers 1 and jelly 2 are passed, is formed into a pipe shape and is elongated long to reach the point just before the rear stage capstan as shown in (B). As a result, the optical fibers 1 are not fixed to the jelly before the rear stage capstan.

Abstract: PURPOSE:To obtain the compensation value of a fuel injection timing sensor in a device in which the timing of fuel injection is adjusted by a microcomputer, by comparing an actual fuel injection timing detected by the fuel injection timing sensor with a reference fuel injection timing set by a digital switch to obtain the difference therebetween, and by displaying and printing out the difference. CONSTITUTION:A reference fuel injection timing is set by manipulating a digital switch 14, and a compensation code conversion table is read out from an ROM 15 by manipulating a key board 17. The outputs of a fuel injection timing sensor 1 and a rotation sensor 2 are connected to input terminals 6, 7. A CPU11 compares a cam phase angle received from a reference angle setting circuit 13 with the cam phase angle of the fuel injection timing sensor 1 and computes the difference therebetween so that the difference is displayed on a display circuit 20 with the use of a binary code conversion table stored in the ROM 15. By setting the displayed code to the digital switch, a microcomputer 3 computes such that the timing of signal transmission from the fuel injection timing sensor 1 is automatically shifted to operate an actuator, thereby the fuel injection timing is automatically coincided with the reference fuel injection timing of a fuel injection pump.

Title: Damper device of magnetic bearing
Inventor: SUGISHITA TAKAHARU
IPC: G02B26/12
Filed: 1985-07-31
Abstract: PURPOSE:To prevent resonance phenomenon by adjusting size of a clearance in the radial direction made by a stationary shaft and a rotating body and absorbing vibration of bearing members caused by resonance phenomenon. CONSTITUTION:Resonance phenomenon occurs by mutual repulsion force between magnets 30, 32 and mass of a rotating body 21, and vibration is going to be larger more and more. But when the rotational speed of the rotating body is increased and entire absorption of resonance energy becomes impossible, fluid existing outside the rotating body 21 goes into and comes out of the second clearance 26 formed by the rotating body 21 and a stationary shaft 23 through a through hole 28. Then, damper effect is given and vibration energy is absorbed, and vibration of related members due to resonance phenomenon can be prevented.
