Title: Installing method for vertical shaft pump
Inventor: TAMURA IKUJI
IPC: F04D29/60
Filed: 1988-02-26
Abstract: PURPOSE:To reduce cost for installing work of a vertical shaft pump by dividing the pump into two portions at a predetermined position below the entrance of an impeller and fixing a lower half including a bell mouth to the bottom of a pit for the pump in advance. CONSTITUTION:At the lower end of an air intake communication pipe 15, a vertical shaft pump is divided into two portions, and a lower half is fixed to the bottom of a pit P for the pump in advance. The dividing line is set below the entrance level IL of an impeller 4. An air intake path 16 is joined, on the wall side, to the air intake communication pipe 15, and the junction is above the lowest water level of the pump. In the above-mentioned structure, when a water level of submergence of the pump is in regions A and B, there is no problem in water discharging function, whereas, when the water level drops to enter into region C for causing an air intake valve 17 to open to introduce the air to the neighborhood of the entrance of the impeller and for causing the water inside an air intake pipe 3 to drop, the pump becomes disabled from lifting water and, as a result, such inconvenience as development of a vortex with air entrainment does not occur. In addition, cost for installing work of the pump is reduced, because a crane only needs to hoist the upper half of the pump and because the height of a building and a crane for the pump can be lowered.

Title: Circuit breaker
Inventor: IMAMURA TAKESHI
IPC: H01H73/04
Filed: 1988-02-26
Abstract: PURPOSE:To stabilize a performance characteristic by making the inner surface of a long groove to the surface in which the frictional force of the contact part between a pin and the long groove is lower than that of the contact part between the pin and the inner surface of a guide groove when the pin moves within the long groove and the guide groove. CONSTITUTION:When large current in the case such as a short circuit flows, the rotational force in the clockwise direction is given to a movable piece 7. At that time, a contact arm 10a is standing still, and only a contact arm 10b rotates with a pin 16 made to push up along a guide groove 14 since an automatic trip 4 is unoperative. The arm 10b stops at its position when the pin 16 reaches the upper end 14b of the groove 14. The pin 16 is energized with a pull spring 17, but moves within the groove 14 against for the force of the spring 17 at the time of this action. The pin 16 slidingly moves within a long groove 15, and rollingly moves within the groove 14 since the friction factor between the pin 16 and the groove 15 is smaller than that between the pin 16 and the groove 14. Consequently the variation of the frictional force in every action when the pin moves within the guide groove is eliminated, and a stable action characteristic is obtained.

Title: Speed detector for elevator drive motor
Inventor: IYODA HIROMI
IPC: H02K11/00
Filed: 1992-03-03
Abstract: PURPOSE:To produce cooling function by constituting a speed detector such that the entirety of the speed detector is separated from the end of a motor on the casing side through the shaft of an independent body located at the end of the motor thereby eliminating stagnation of high temperature atmosphere between the casing side end and a speed detection end. CONSTITUTION:Heat generated in a motor and transmitted on a motor shaft 4 is dissipated not through the motor shaft 4 but through the rotary shaft 11 of an independent body and the heat generated in the motor and transmitted on the casing 3a is also dissipated through a bracket 12. Furthermore, since the entire speed detector 5 is separated by at least the end length of motor shaft from the side end of the casing 3a, conventional stagnation of high temperature atmosphere is suppressed. Consequently, transmission of heat into the speed detector 5 is suppressed and an electronic circuit section 5c is kept at a normal temperature and does not function erroneously. In other words, heat is not transmitted to an electronic circuit having allowable temperature lower than that of the motor and normal controllability can be sustained for the motor.

CONSTITUTION:A slant detecting switch 8 is connected betwee a meter unit 1 and a gage unit 2 in series. When an accelerating or decelerating speed or inclination exceeding specified values is yielded in a vehicle, a ball 15 in the slant detecting switch 8 is moved on a conical surface 9a of a container 9. The ball 15 is deviated from an groove 10 and contact points 11 and 12 are opened. Therefore current conduction between the meter unit 1 and the gate unti 2 is cut OFF. Even though the liquid level in a fuel tank 6 is fluctuated and a float 7 is moved up and down, a pointer 1b stays at the indicating position before the liquid level is fluctuated. Therefore, the state of the vehicle can be accurately detected.

Title: Underwater granulation of finely powdered coal
Inventor: KITA SHIYUUICHI
IPC: C10L5/14
Filed: 1980-04-07
Abstract: PURPOSE: When finely powdered coal is granulated in water, the oil sticking to the granules is removed by pouring water under stirring to prevent the increase in the water held between granules that is caused by agglomeration of granules and permit the separation of slimes, thus saving the consumption of oil.  
     CONSTITUTION: Finely powdered coal and an oil as a binder are charged into the pregranulating tank 2 and made to pass through three granulating tanks 3 under stirring with turbin blades, resulting in almost sphere particles. Then, these particles are sent together with a dispersion medium to the rinsing tank 4 where the particles are stirred by both air-blowing from the pipe 6 and blades 7 under feeding clean water from pipes 5 and 5' to remove the excess oil and slimes sticking to the particles and to float them to the upper part of the tank 4. The rinsed particles are excluded out of the bottom of the tank, drained on the sieve 8 and transferred with conveyor 9. In the meantime, the excess oil on the upper part of the tank 4 (together with slimes) is sent to the separator 10 and to the decanting tank 12 together with the water passing through the sieve 8. The overflowing fraction from the tanks 11 and 12 is returned back through pump 13 to the tank 3.

Title: Method for detecting position of light pen
Inventor: FUJINAGA TAKASHI
IPC: G06F3/037
Filed: 1983-03-18
Abstract: PURPOSE:To compensate a light pen position detecting error due to the characteristic change of the light pen or its signal system by allowing the light pen to touch upon the specific position of a display screen only once. CONSTITUTION:If the light pen is allowed to touch upon the display position of a specific pattern PAT, a light pen output pulse signal WP is generated when scanning light passes through the light pen position. Consequently, a vertical positional signal LA and a horizontal positional signal CA are latched by latch circuits 1, 2 respectively. Since the positional signal LA latched by the latch circuit 1 corresponds to the vertical position of the specific pattern PAT, a detecting signal Ly is outputted from a detecting circuit 5. An arithmetic circuit 7 calculates the difference between signals CA and CAX at the timing generating the detecting signal Ly and the difference value is stored in an internal register. The difference value (x) is inputted to an arithmetic circuit 8, the horizontal positional signal CA obtained when the light pen is allowed to touch upon an optional position is inputted to the other terminal of the arithmetic circuit 8 and the difference signal is outputted to be compensated.

Filed: 1994-03-16
Abstract: PURPOSE:To prevent the performance of an analog circuit from being deteriorated when a digital circuit is operated by separating a power source for the digital circuit and the analog circuit by means of a regulator. CONSTITUTION:Before starting exposure actuation, the regulator 22 is turned off and a range-finding circuit 23 and a photometry circuit 24 are not operated. When both circuits 23 and 24 shift from an off-state to an on-state, the regulator 22 is turned on. Thereafter, a boosting clock is stopped and a microcomputer 21 is operated only by charges accumulated in a capacitor 14 in order to reduce the influence of noise. Then, an IRED 26 is pulsatively driven by the microcomputer 21. At such a time, the charge of the capacitor 14 is used for light emission by the IRED 26 and a load current for the circuit 23, so that voltage drops. However, stable voltage is supplied to the circuits 23 and 24 owing to the control by the regulator 22, and the influence of the noise is reduced.
