Title: Drinking water storage device
Inventor: TAKANO KEIJI
IPC: E03B11/02
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To store the tap water by providing a stop valve in which a flow passage is opened with the pressure of the tap water at a suction port of a water storage tank to allow the tap water to flow into the tank, the flow passage is closed by the pressure drop to store the tap water in the tank. SOLUTION: When an opening/closing valve 6 provided on a lower connection pipe 5 is opened, and a faucet 18 is turned to release an upper tap water piping 19 into the atmosphere, the water pressure in a tap water piping 16 is moves a valve body 10 of a stop valve 9 against a spring 13. The tap water is fed into a tank body 2 of a water storage tank 1, the pressure in the tank body 2 becomes equal to the pressure of the tap water, and the tap water is discharged from the faucet 18. When the tap water is inevitably cut off in a disaster such as an earthquake, an unexpected accident of the tap water piping, or the tap water saving, a valve body 11 of the stop valve 9 is seated on a valve seat 12 to stop the tap water by the urging force of the spring 13 due to the pressure drop of the tap water in the tap water piping 16, and the tap water is stored in the tank body 2.

Title: Rotary electric machine
Inventor: EJIMA TAIZOU
IPC: H02K11/00
Filed: 1983-02-08
Abstract: PURPOSE:To prevent the damage of a power transmission unit and to improve the reliability of a rotary electric machine by disposing a detecting coil for detecting the amount of variation in the magnetic flux through a gap on an output shaft, and interrupting the energization of a motor by the detected output. CONSTITUTION:A ring-shaped exciting coil 8 for generating an eddy current is disposed via a gap on a transmission shaft on the outer periphery of a trasmission shaft 6. AC power sources 9a-9d for flowing AC currents to the coil 8 are formed by disposing a plurality of detecting coils 9 arranged through a gap on the outer periphery of the shaft 6 at an equal interval of quadrants. When magnetic fluxes are generated from the shaft 6 by the eddy current of the shaft 6, the output is generated on the basis of the variation in the magnetic flux. The power source of a motor is deenergized and interrupted on the basis of the outputs of the coils 9a-9d. In this manner, the damage of the gear and the shaft of the power transmission unit can be effectively prevented, and a rotary electric machine having high reliability can be obtaind.

Title: Calendar watch
Inventor: KAMIJIYOU NORIYUKI
IPC: G04B19/24
Filed: 1978-02-22
Abstract: PURPOSE: To reduce wasteful load and prolong battery life by coupling a data feed Geneva gear and transmission member with a slight backlash at the non- transmission time.  
     CONSTITUTION: When it becomes 0:00 AM upon lapse of 24 hours, the first transmission member 7 which is formed with a Geneva gear and makes backlash coupling with a drive wheel 6 and the protrusion 6a of the drive wheel 6 couple, causing the member 7 to turn. This causes the second transmission member 8 to be turned by the postioning member 9 provided to the member 7, then a display wheel 2 is fed for 1 day. This minute backlash coupling of the drive wheel 6 and member 7 obviates application of wasteful load on the drive system at the times other than the time when the display wheel is fed, prevents the consumption of unnecessary power and prolongs battery life. When the member 8 is manually turned, the member 8 turns by jumping over the member 9, thus the month end correction or other may be accomplished while checking with tactile sensation.

Abstract: PURPOSE: To increase the space efficiency of the electromagnetic device by constituting the electromagnetic mechanism with a magnetic flux generating stationary member of rectangular parallelopiped form and a moving member of rectangular parallelopiped form including the driving shaft of camera shutter blades.  
     CONSTITUTION: While no current is supplied to the coil 33' of an electromagnetic device A, a lever 46 is turned and energized clockwise by the clockwise turning energizing force of a spring 48 and therefore shutter blades 51 and 52 are respectively energized in the directions of right and left, thereby maintaining the shutter close state. Next, when current is supplied to the coil 33' through shutter releasing, a bobbin 31 jumps out in the right direction while being guided by shafts 37, 38 and therefore the lever 43 is turned counterclockwise about the shaft 42 and at the same time the lever 46 is turned counterclockwise about the shaft 47 against the turning energizing force of the spring 48. This causes the shutters 51 and 52 to rapidly move in the directions of right and left respectively to overlap shutter openings 53 and 54, thus starting exposure to the film surface. Thereby, the space efficiency in the camera of the electromagnetic device may be increased.
