Abstract: PURPOSE:To reduce the occurrence of abrasive powder, by forming a dynamic pressure generating groove in either of the opposed surfaces between a valve seat and a valve body, and making the valve body rotatable in one direction along at the optional position. CONSTITUTION:A valve body 23 being set up in a position to be opposed to a valve seat 24 is one that the whole outercircumference of a permanent magnet 30 is convered with a back plate 31 and a surface plate 32 of ceramics, and a dynamic pressure generating groove 41 is formed in each surface of the back plate 31 and the surface plate 32. The permanent magnet 30 is magnetized to sextupoles, and it is rotated synchronously with a rotating magnetic field to be formed by a laminate seat coil 26b. When a flow rate is made smaller, the valve body 23 is made to come close to the valve seat 24 as being rotated, so that solid contact between the valve body 23, where dynamic pressure is produced, and the valve seat 24 will not occur.

IPC: H04N5/335
Filed: 1992-06-30
Abstract: PURPOSE:To reduce the effect of a white flaw by employing a memory means in a form that a picture signal written at first is read out at last. CONSTITUTION:Picture information on a line arranged above is read out of a CCD chip 3 and is written in a first-in last-out FILO memory 4 in a form that information written at first is read at last. The information written in the FILO memory is considered to be information of an inverted real image as shown in a pattern 4a. Since the picture is read in the opposite sequence to that at write is read, the information is read out of the lower side of the pattern 4a toward the upper side (from the lower side of the picture toward upper side. Then the picture information read out of the FILO memory 4 is fed to a conventional monitor 5 and displayed sequentially from the upper part of the screen. Thus, a normal picture 5a is displayed on the screen of the monitor.

Title: Water-proof acoustic electronic watch
Inventor: WATANABE MINORU
IPC: H04R1/00
Filed: 1983-09-20
Abstract: PURPOSE:To make it possible to usually hold water-proofness but to perform the control of atmospheric pressure in a watch if necessary, by such constitution that the vent orifice provided to a part of an air-tight case is opened and closed by an atmospheric pressure adjusting button. CONSTITUTION:When an atmospheric pressure adjusting button 8 is pressed to release force applied to an O-ring, the interior and exterior of a watch case are brought to an air flowing state and the internal and external pressures of the case are brought to a equilibrium state. The watch has an air-tight case structure and usually has water-proofness and sweat-proofness but, when imbalance in the atmospheric pressure in the interior and exterior of the watch is generated for some reason, the cone of a speaker 3 receives the repetition of pressure variation to lose flexibility and the variation is brought in the frequency characteristics of the speaker. On the other hand, the inner and outer atmospheric pressures of the watch are brought to an equilibrium state by pressing the button 8 and the cone is returned to a normal position and inherent speaker property can be developed.

Title: Hot scarfing method for steel slab
Inventor: IWANAGA TAKEO
IPC: B23K7/06
Filed: 1979-12-27
Abstract: PURPOSE: To improve productivity by eliminating surface flaws of a steel slab at a high temperature, by scarfing a flaw part by a partial hot scarfer which is transverse in the width direction.  
     CONSTITUTION: Partial hot scarfer 4 eliminates flaw 5 by scarfing. The dotted-line arrows show the scarfing trace of the hot scarfer. Next, entire-surface hot scarfer 3 scarfs the entire surface layer of a steel slab. The solid-line arrow shows the trace of the entire-surface hot scarfer. The scarfing of the partial hot scarfer should be doen more  deeply than the entiresurface hot scarfer to eliminate flow 5, and consequently although the scarfed part 6 remains in a transverse-groove shape on the surface of the steel slab after the entire-surface scarfing, this disappears by the next- stage rolling, so that there is no problem.

Title: Solar heat-water heater
Inventor: KITA SHIGEHIRO
IPC: F24S10/95

Abstract: PURPOSE:To permit to heat water in a heat accumulating tank, whose volume is proportional to the receiving amount of solar enerby, to a constant temperatue automatically by locating the heat dissipating section of a heat pipe in the heat accumulating tank. CONSTITUTION:The heat dissipating sections 1a of a plularity of heat pipes, whose heat collecting sections 1 are located at a heat collector, are located in the heat accumulating tank 2 through packings 7. An opening and closing valve 3 is connected to the tip end 1b of one heat pipe among a plurality of them. Water-tightness of the heat accumulating tank 2 and the tip end 1b is kept by a packing 8. Feed water, passing through the opening and closing valve 3 connected to a feed water pipe 4, is discharged into the heat accumulating tank 2 through the opening 5 of the feed water pipe and is supplied to the bottom of the tank 2 through the feed water pipe 6. The heat collecting section 1 of the heat pipe receives the solar beams and the temperature of refrigerant therein is risen. When the temperature of the refrigerant arrives at a value, the opening and closing valve 3 is opened by a pressure rise, water feeding is begun, and the heat dissipating section 1a is cooled by the feed water. When the temperature of the heat dissipating section 1a arrives at a value by the cooling of the feed water, the valve 3 is closed, the heat of the heat collecting section 1 moves sequentially to the heat dissipatong section 1a to heat the feed water. When the temperature of the feed water arrives at 60 deg.C, water feeding is restarted and heated water is pushed up by the feed water, therefore, the heat dissipating section 1a is cooled again and water feeding is stopped when the temperature of the section 1a has arrived at 30 deg.C. Heated water having a temperature near the set temperature 60 deg.C is reserved in the tank 2 by repeating above-described cycles.
