Title: Single-phase autotransformer
Inventor: TOYOSHIMA YOSHIMASA
IPC: H01F29/02
Filed: 1981-03-06
Abstract: PURPOSE:To prevent and change of tertiary voltage according to the position of a tap by winding one side of two exciting winding, to which constant voltage is applied and which is connected in series, and tertiary winding on the same core. CONSTITUTION:The tertiary winding 30 and the exciting winding 50 are wound on a main leg 72, and the exciting winding 52 connected in parallel with the winding 30, tap winding 4 and the exciting winding 51 connected in series with the winding 50 are wound on a side leg 70. The excitation of the core leg on which the winding 50 is wound does not change according to the position of the tap because voltage between both terminals u, v of the winding 50 is constant. Accordingly, the voltage of the winding 30 is also constatnt regardless of the position of the tap. Since the induced voltage of the tap winding is constant, stepping voltage is also constant, the width of the voltage changes at the plus side and the minus side is also equalized, and the transformer is easily controlled.

Title: Vacuum monitoring device for vacuum switch apparatus
Inventor: TORIIE HIDEAKI
IPC: H01H33/66
Filed: 1992-02-19
Abstract: PURPOSE:To make sensing free from influence of an eventual switching surge, etc., and at a low degree of vacuum by coupling a light emission part with a light reception part and a vacuum part of a vacuum switch apparatus through a photo-transmission path of optical fiber, and using the output of the light reception part as a vacuum monitor signal. CONSTITUTION:A light emission part 16 emits for example a CO2 laser beam, among which the beam with a wavelength 10.6mum is selected by a wavelength selecting element 20, passed between insulative cylinders 2 of a vacuum valve 1, passed through an optical fiber 15 to be fed to a light reception part 17. When the internal pressure is heightened by intrusion of the insulative gas such as SF6 gas above the level in the case the vacuum in the valve 1 is held at a normal level, the incident photo-quantity to the light reception part 17 decreases proportionally. A vacuum judging part 18 senses deterioration of the vacuum from the electrical signal given in accordance with this photo- quantity and issues an output for alarming or displaying. This enables monitoring of the vacuum with variation of the optical signals in direct compliance with the change in the vacuum of the vacuum part without resorting to change in the electric field.

Title: Crossover balance type relief valve
Inventor: HIRATA YUTAKA
IPC: F16K17/10
Filed: 1979-03-19
Abstract: PURPOSE: To prevent the phenomenon of relief pressure fall at the time when the upper stream side relief valve starts blowing by making the rod as a separate body from the pilot valve seat.  
     CONSTITUTION: When the liquid pressure of port 36 rises, the liquid pressure of spring chamber 33, which is connected to port 36 through throttle path 35, rises also, and it pushes rod 22 to the left and opens poppet 27' via rod 22'. By this, spring chamber 33' links to the tank side through spring chamber 39'. When the liquid pressure of port 36 exceeds the preset value, poppet 27 opens, spring chamber 33 links to the tank through spring chamber 39, and plunger 21 moves back, but rod 22 receives back pressure from throttle path 37 and maintains poppet 27 in open state. Relief oil which has flowed into cylindrical seat 30 pushes cylindrical seat 30' but oil in spring chamber 33' is discharged from throttle paths 35', 37'. As a result, the damping force is small, and plunger 21' and cylindrical seat 30' move quickly to the left.

Abstract: PURPOSE:To easily detect the sleep by non-contact by detecting a body motion pattern of the human body at the time of sleep by non-contact with the human body. CONSTITUTION:By a piezoelectric element 4 provided in bedding, a minute body motion (hereafter, referred to as a 'fine body motion') of the body propagated by activity of the heart and breathing activity of the human body, or a large body motion (hereafter, referred to as a 'coarse body motion') of the body such as going-to-bed, getting-up and turning-over in bed is detected. A detecting signal is filtered, amplified, rectified and integrated through a filter 6, a rectifier 8, an integrator 9, etc., and thereafter, in accordance with a level of an integral signal, absence, being in bed, and a body motion are decided by a deciding means. When the signal is zero, when there is a fine body motion, and when there is a coarse motion, they are decided to be absent, be in bed, and be a body motion, respectively. When it is decided to be in bed, a time counting operation is started by a timer 13, and when the time counting time exceeds a set time determined in advance, it is decided that the human body is sleeping on bedding.

Abstract: PURPOSE:To make a filter changer ever so easy, by installing a space keeping device in the pressure chamber installed separately from a body case, and when a filter is attached, making the pressure chamber adhere closely to this filter, while forming a clearance there at the time of filter detachment. CONSTITUTION:A clean air supply opening 2 is installed in an upper part of the working space 4 formed in a body case 16, on top of which a filter 1 is placed.

In addition, a seat 7 is locked with a screw to an under-head apart more than plate thickness of the seat plate 40 from a screw head of the screw 6. Therefore, when the filter 1 is changed, a front cover is removed and the screw 6 is loosened to some extent whereby the pressure chamber 3 goes up, thus a clearance is formed between the chamber and the filter 1 so that a filter change is easily performable.

Title: Sanitary cleaning device
Inventor: MATSUI HIROYUKI
IPC: E03D9/08
Filed: 1988-02-16
Abstract: PURPOSE:To have accurate sensing of the rate of flow by allowing fluid to flow in from above a convolution chamber downward to exhaust in horizontal direction along the axis, and sensing the revolving speed of a sphere rotating proportional to the rate of flow of the fluid. CONSTITUTION:Water passing through a cleaning main water line flows into a convolution chamber 29 from the inlet 30 of a rate-of-flow sensor and comes into a warm water tank from an outlet 34 while rotating. The torque of this water causes revolutions of a sphere 35 in proportion to the rate of flow. The revolutions hinder the light emitted from a light emission part 37 for a light receiving part 38 once per turn so as to allow it to generate signals with frequency equal to the number of revolutions. On the basis of these signals, the rate of flow is automatically adjusted to a value set as desired by operator, and the warm water stored in a warm water tank is pushed out to jet out of a cleaning nozzle. Thus, local cleaning is conducted. This enables accurate sensing of the rate of flow and keeping of the rate of flow to any desired value by the user.
