Title: Electrical contact
Inventor: SASAMOTO TAKESHI
IPC: H01H1/02
Filed: 1980-03-19
Abstract: PURPOSE: To inhibit the occurrence of contact inseparable trouble due to melt- sticking at the time of sending a current and shutting off it and prevent an increase in the contact resistance when switching action is repeated many times by adding at least one of Ru and Re to W.  
     CONSTITUTION: Electrical contacts are obtd. by adding 40W60wt% at least one of  Ru and Re to W. Since the surfaces of the contacts are protected with Ru or Re  oxide films with high electric conductivity, an increase in the electric resistance due  to the oxidation and nitriding of W can be prevented. Ru and Re are superior to  Ag in arc resistance, so contact inseparable trouble due to melt-sticking is not  caused. The contacts are fit for sending a relatively large current and shutting off it  with relatively small contact force in an electromagnetic relay, etc.

Title: Vacuum cleaner
Inventor: ONO TAKASHI
IPC: A47L9/18
Filed: 1994-02-08
Abstract: PURPOSE:To keep dust-collecting water rotational and stabilize dust collection efficiency by providing a valve that opens when atmospheric pressure in a water pan goes below a predetermined value in comparison with atmospheric pressure outside the water pan and making the dust-collecting water flow in response to air sucked from an air inlet. CONSTITUTION:A water pan 3 has a suction 6 to introduce air containing dust, a valve 13 is provided on the peripheral wall, an air inlet covered by the valve 13 communicates with a filter 14 and an air duct 15, open to outside air. If the amount of suction decreases extremely due to an accidental suction of a curtain during cleaning, atmospheric pressure in the water pan drops abnormally below the atmospheric pressure outside the water pan 3. When the difference in the atmospheric pressures exceeds a certain value, the valve 13 opens and introduces outside air directly, making the dust collecting water 13 continue to rotate in the same direction as sucked air containing dust and preventing an electric motor rotate at an abnormally high rate.

Title: Torque limiter
Inventor: OSEKO HISAAKI
IPC: F16D7/02
Filed: 1989-02-15
Abstract: PURPOSE:To stabilize torque for a long period and also make it possible to obtain desired torque by putting relative moveable portions in a non-contact state to each other via a gap when torque is generated by means of hysteresis caused by rotation. CONSTITUTION:When an inner tube 22 made of magnet and an outer tube 26 having magnet particles 27 enclosed therein are put in turning movement relative to each other, each of the magnet particles 27 follows movement of an outside magnet and is rotated independently. Torque is generated between the inner tube 22 and outer tube 26 by means of magnetic hysteresis caused by the rotation. Then, when a magnet 33 and an enclosing body 34 having magnet particles 35 enclosed therein are put in turning movement relative to each other, each of the magnet particles 35 follows movement of the outside magnetic pole and is rotated independently. Torque is generated between the magnet 33 and the enclosing body 34 by means of hysteresis caused by the rotation; since then the inner tube 22 and outer tube 26, and the magnet 33 and the enclosing body 34 are in non-contact state via respective gaps, torque is stabilized over a long period of time and also, since during manufacture the process of varying magnetic properties is not carried out, desired torque can be obtained.
