Abstract: PURPOSE: To obtain an output flow rate substantially in proportion to the level of an electric current applied to a coil, by providing a valve member which is rotationally displaced in proportion to the level of an electric current being applied, whereby the linear operational range can be reduced to the greatest possible extent.  
     CONSTITUTION: A valve member 31 serves to shut off an inlet port 11 from an outlet port 12 and thereby communicate the inlet port 11 with a relief port 13. When an electromagnetic coil 18 is turned on, a magnetic path consisting of a yoke 17 and a core 19 is formed so that the core 19 is drawn in the downward direction. As a result, a flange portion 20 is urged in the direction in which the core 19 is drawn as mentioned above. At this time, the flange portion 20 or the core 19 is oscillated owing to a ball 32 inserted between an projection 21 and a recess 22. Namely, the core 19 and valve member 31 are oscillated clockwise in proportion to the level of an electric current applied to the coil 18. As a result, the relief port is gradually restricted, while the outlet port 12 is gradually opened, so that a fluid flows to the outlet port 12 at an output flow rate in proportion to the level of an electric current applied to the electromagnetic coil 18.

Title: Self-positioning system for unbalanced point
Inventor: MATSUMOTO SHIGERU
IPC: G01M1/08
Filed: 1982-02-02
Abstract: PURPOSE:To enable an unbalanced point of an object to be measured to be brought to a stop at a given position, by a method wherein, when the number of counts of an angle signal from a preset counter coincides with the number of presets through acceleration of a speed of an object to be measured, a drive motor is brought to stop running. CONSTITUTION:By means of signals from a tachometer 3 and a voltage feed circuit 7, rotation of a motor 2 for driving an object 1 to be measured is controlled, in order, to start, accelerate, run at a constant speed and accelerate it. After starting of a deceleration control, an angle signal of a rotary encoder 11, which outputs a unit angle by means of a signal from a rotation angle generating means including a pickup 12, is inputted to a preset counter 20, and when the number of counts coincides with a preset number, the motor 2 is brought to stop running through the working of a control circuit 9. This permits the unbalanced point of the object 1 to be measured to stop at a given position with neither marking nor sensor, and permits the improvement of precision and rapidity.

Filed: 1992-01-31
Abstract: PURPOSE:To contrive the small space of a large-sized shield room of a linear acclarator and the like of a high energy X-ray exceeding 10 MV and build labyrinth structure of low scattering leakage for the entrance of the shield room. CONSTITUTION:The medical radiation shield room comprises labyrinth structure projected so as to Z-shapedly have access to an irradiation room in accordance with an irradiation partition wall 5 and a projection labyrinth protection wall 3 at an end of an irradiation room protection wall 4 and a pair of projection walls 6, 7 built so that a temporary scaring face may get an obstructed view a protection door 1 as shown on a plotting line 31 in the righthand figure at each corner of the labyrinth structure. Because the temporary scattering face is not seen through the protection door 1, a scattering ray incident on the door can be reduced in the order of figures in the case of an X-ray and one figure in the other case of a neutron, compared with the conventional. In addition, since a range surrounded by another line 32 in the righthand figure becomes spacesaving, with the conventional shield this can contribute to the construction of room arrangement environment.

Inventor: NAKAMOTO HIROYUKI
IPC: H01S5/026
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To stably obtain a driving signal for driving a laser diode. SOLUTION: An oscillation output signal from an oscillator 1 is applied to a laser diode LD after being amplified by an output amplifier 2. The laser diode LD is turned 'on' at every high frequency. Since a laser beam is emitted by multi-mode at rise of a laser diode, the laser beam is continuously emitted by multi-mode. Furthermore, since frequency characteristic of the output amplifier 2 is set to make cut-off frequency lower than doubled oscillation frequency of the oscillator 1, harmonic is cut off by the output amplifier 2.

Title: Fuel injection time changing apparatus for diesel engine
Inventor: SUMA TOSHIAKI
IPC: F02D1/16
Filed: 1980-02-12
Abstract: PURPOSE: To delay the fuel injection time in a fuel injection by nullifying the volume of the plunger stroke which results from the movement of the plunger in order to increase the pressure by shifting the piston in other device.  
     CONSTITUTION: In the compression cycle of a fuel injection pump 1, a plunger 2 begins elevation, and the fuel between the head 3 of the plunger and a fuel passage 4 is compressed and the pressure increases. When the pressure of the fuel surpasses the force of the spring 7 in an adjusting device 5, the piston 6 begins to move rightward, and shifts by the volume of the stroke of the plunger 2 of the pump 1, and the compression of fuel is not developed during this time. When the piston 2 shifts untill it contacts with a stopper 8, and stops, the compression of fuel starts again, when the pressure reaches the valve opening pressure of a fuel valve 9, fuel injection starts. Thus, the time of fuel injection can be delayed by the time during which the piston 6 is moving.

Abstract: PURPOSE:To effectively start a motor by coupling to a load through a load moderator at the time of starting a permanent magnet rotor type synchronous motor, thereby preventing the motor from becoming impossible to start. CONSTITUTION:A drive boss 30 is secured to a rotational shaft 3 of a permanent magnet rotor type synchronous motor 1. A rotational shaft 29 of a load (e.g. a fan 27) is rotatably supported via a bearing 28, and further extended to be secured to a driven boss 32. The shafts 3 and 29 have the same diameter and are disposed on the same axis, the bosses 30, 32 are contacted at the end faces with each other to be slidable. A spring 33 having an inner diameter larger than the outer diameter of the boss is secured at one end 33a to the boss 30, and at the other end 33b to the boss 32. When the motor 1 is started, torque is transmitted lightly through the spring 33, a load is gradually increased until the spring is wound on the both bosses. When the spring is completely wound, it is shifted to a full load state. In this manner, the starting mistake of the motor can be prevented, thereby effectively starting the motor.
