Title: Ultrasonic flowmeter
Inventor: OZAKI SADAHIKO
IPC: G01H3/00
Filed: 1979-05-10
Abstract: PURPOSE: To assure good accuracy over a long period of time by adding the voltage output part and change-over circuit part for providing an ultrasonic cleaning function to the ultrasonic transmitter-receiver.  
     CONSTITUTION: The flowmeter is constituted by a voltage output part which applies a fixed pulse voltage to ultrasonic transmitter-receivers 2a, 2b and a change- over circuit which changes over the system from a flowmeter circuit part 3 to the voltage output part 4 at every fixed period. At a fixed period of every period when the deposition of scale, etc. is anticipated, the ultrasonic transmitter-receivers 2a, 2b and flowmenter circuit part 3 are disconnected by the change-over circuit part 5 and in place, the voltage output part 4 is connected thereto, thence in the voltage output part 4 the excitation voltage is generated by the excitation trigger signal from the change-over circuit 5. The excitation voltage goes through the change-over circuit part 5 and excites the vibrators of the ultrasonic transmitter-receivers 2a, 2b. The deposits such as scale on the inside wall surface in the piping are removed by the sound pressure energy thus generated. Hence, the good accuracy may be assured stably over a long period of time.

Title: Light modulator
Inventor: FUJITA AKIRA
IPC: G02B6/00
Filed: 1979-05-11
Abstract: PURPOSE:To obtain a quick response in a simple constitution, by opposedly and adjacently providing an optical fiber which is so set that the exit side of light may vibrate responding to the incident sound wave and a fixed fiber. CONSTITUTION:The light radiated from a light emitting device 5 is caused to enter both ends of one side of an optical fiber 6, and it is so set that this light may leave an exit plane 63 and enter an optical fiber 7. When sound is emitted in this state, the sound is transmitted to the fibers 6, 7. Of the fiber 6, the part 62 mechanically fixed by a clamp 10 does not vibrate, but since the end part 61 is not fixed, the end vibrates responding to the sound wave. As a result, the exit plane 63 and fiber 7 may be deviated in axis due to vibration, so that the intensity of light entering the fiber 7 may be modulated in response to the sound.

Title: Water soluble photosensitive composition
Inventor: SATO TOSHIAKI
IPC: G03F7/033
Filed: 1985-03-22
Abstract: PURPOSE:To obtain a water soluble photosensitive composition from which a polyvinyl alcohol (PVA) polymer in a cured part is not removed during development by blending a PVA polymer having SH groups in the molecule with a radical polymerizable unsatd. compound and a photopolymn. initiator. CONSTITUTION:Vinyl acetate is reacted with a very small amount of thiolacetic acid under heating, a polymn. catalyst is added, and polymn. is carried out. The resulting polymer is reacted with a prescribed amount of thiolacetic acid to obtain a polymer having SH groups at the terminals of the polymer. Vinyl acetate may be copolymerized with allyl thiolacetate to obtain a polymer having SH groups in the molecule. The polymer having SH groups is saponified to produce a PVA polymer having SH groups at the terminals of the molecule or in the molecule. A water soluble photosensitive composition is obtd. by blending the PVA polymer with a radical polymerizable unsatd. compound having an ethylenic double bond and a photopolymn. initiator. When the composition is exposed and developed, the water solubility of the PVA polymer is reduced because the polymer has SH groups, so the PVA polymer in the cured part is hardly leached out to give a superior resin relief.

Title: Cooling cylinder for rolling table
Inventor: PLOCIENNIK UWE
IPC: F25D9/00
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To enable the adjustment of cooling characteristics of a cooling cylinder in a roller table by forming the cooling cylinder for cooling the roller table in a shape in which the cross section of a flowing passage is smaller at a shifting part to the vertical directional portion than a flow-out opening part and the vertical directional portion is curved to the outside. SOLUTION: Air for cooling a flowing passage 3 flows through a narrow shifting part 4 and flows out in the tangential direction along the surface of a curved vertical directional portion 5. The air flowing out near rollers 1 is turned therefrom and lastly separated at a fixed angle. In the case of a turbulent flow, a jetted flow is accompanied with a stationary medium and the width of the jetting flow become wider and the air speed is reduced. Together with the reduction of air speed, a material to be cooled on a roller table is vigorously cooled by increasing a retention time in the air. Many cooling cylinders 2 are side by side combined through an insulating member to form an assembly. The assembly is slid to the roller table and the flow opening part 6 is obstructed by an insulating member to adjust the cooling air quantity.

Title: Method and apparatus for tightly plugging drum with pressure applied
Inventor: UTAMURA MASARU
IPC: B65B31/06
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To eliminate deformation after cooling, buffer a filling temperature, reduce filling time and facilitate inspection for fine leakage with applied pressure held by coating a cap with a cylindrical body while a plug is slightly screwed into the cap, applying pressure to inside a drum with gas led and further tightening the plug for sealing. SOLUTION: Since airtightness of a plug (c) to be used for applying pressure and sealing a drum depends on a degree of tightening of the plug (c), if a cap- like cylinder 1 is put over with the plug (c) slightly screwed initially and pressurized gas is blown in from an intake port 1, air is fed through a slit between the plug (c) and a cap screw (b) to increase a pressure inside the drum. Subsequently, after the plug (c) is further tightened by a plug rotating means such as a spindle 2 in a pressurized state, this apparatus is removed. Thus inefficient operation at the time of filling can be eliminated, shrink deformation of the drum at the time of cooling after high-temperature filling can be prevented, and leakage inspection on a fine region in leakage inspection can be easily performed.
