Title: Reduction gear unit
Inventor: MIDORIKAWA KATSUAKI
IPC: H02K7/116
Filed: 1990-08-30
Abstract: PURPOSE:To obtain a highly efficient reduction gear unit, which causes no friction loss even when a worm wheel is subjected to thrust, by employing a rotary output shaft penetrating through the center of the worm wheel freely rotatably thereby transmitting rotary force through a spring and a spring guide. CONSTITUTION:A gap is provided between a rotary output shaft 4 and a worm wheel 3. In other words, the rotary output shaft 4 penetrates through the center of the worm wheel rotatably. When a motor 9 rotates, the worm wheel 3 is subjected to thrust in the direction X. A first spring guide 11 coupled with a first spring 10 rotates as the worm wheel 3 rotates. Since the first spring guide 11 is pressed strongly in the direction of the first rotary body 14, the rotary force is transmitted through the frictional force thus causing rotation of the rotary output shaft 4. Consequently, thrust causes no frictional loss because the worm wheel does not slide on the housing or the like.

IPC: E03B11/06
Filed: 1987-09-16
Abstract: PURPOSE:To obtain a simple and effective method to store water by supplying water, at the normal time, by means of closed storage, while replacing the water with new one by the water pressure of city water and at the time of suspension of water supply, making a valve at the top of the water tank open so that air flows in to prevent a back current of water to the main pipe of city water, and thus stopping water supply to the water tap. CONSTITUTION:Water at the normal time goes through a primary side water supply pipe 2, and is poured out in the water tank from a discharge port 2-a, and is supplied from a water intake port 3-a on a secondary side general purpose water supply pipe 3 and a water intake port 4-a on a secondary side drinking water supply pipe 4, while circulating in the water tank. When a suspension of water supply occurs, and the pressure in the water tank decreases, an air intake valve 6 at the top of the water tank 1 is opened, and air flows into the water tank. At the same time, the water in the water tank is sucked in from the discharge port 2-a on the primary side water supply pipe 2, gives a back current, and stops at the water level at the discharge port 2-a. In order to keep the water amount of the back current minimum, the height of the discharge port 2-a is made as high as possible. Since the water intake port on the secondary side drinking water supply pipe 4 is located at a low position in the water tank, water supply is continued.

Abstract: PURPOSE:To detect the absolute position of a moving body, by generating two phases of sine wave signals 90 deg. in the phase difference spatially according to the movement of the moving body to detect each voltage value thereof. CONSTITUTION:A microprocessor 2 in a computer outputs a hold command (e) to each of sample holding circuits 31 and 32 to sample and hold values of respective sine wave signals Va and Vb based on the timing signal inputted at each fixed cycle from a timer 1. Meanwhile, analog values of the sine wave signals Va and Vb are converted into digital values with a specified accuracy with respective A/D converters 41 and 42 to be inputted into the processor 2 passing a bus (f) at each specified cycle. Then, with these digital inputs used as values of Va and Vb, the value of alpha is computed with the value of V as 0 by the processor 2 at each cycle. Then, among the values thus obtained, the value alpha is determined to ensure than the codes of the sinalpha and cosalpha coincide with codes of the Va and Vb respectively. The value alpha thus determined gives the position information indicating the absolute position within one cycle of two phases of signals.

Filed: 1982-12-24
Abstract: PURPOSE:To achieve an optimal O2 concentration control by performing an intermittent integrating operation only when the shortage of O2 continues while the adjusting function is basically locked against a load variation. CONSTITUTION:As a main steam flow rate signal SF varies exceeding a preset load variation factor, a monitor 23 turns ON. Upon the turning ON of the monitor 23, a signal thereof enters a transfer contact 20 through a delay 24 and with the switching of the contact from (b) to (a), a target value SV of O2 concentration is inputted into a low selector 4'. In the normal case, the SV value is selected from the low selector 4' to enter an adjustor 5 and therefore, deviation of the adjustor 5 turns to 0 and a locking is done without integrating operation. On the other hand, when O2 concentration (d) or (e) lowers below the target value SV, a signal either A or B is outputted from the low selector 4' to has the adjustor 5 performing an intermittent integrating operation and a control is done to elevate the O2 concentration.
