Title: Finder device
Inventor: OMIYA AKIO
IPC: G03B13/12
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a finder device capable of surely obtaining a regular visual field range through an aperture frame formed on a visual field switching plate even when the visual field switching plate is not positioned with high precision at the middle position. SOLUTION: Since an L-size visual field aperture frame 31 is formed so that its two sides parallel with the moving direction of the visual field switching plate 27 may be longer than the corresponding two sides of a visual field frame 26, the visual field of the finder device 5 is kept L-size visual field as regulated even when the plate 27 is somewhat deviated back and forth in the middle position where the plate 27 is not precisely positioned. Thus, even though a semicylindrical spring part 28a formed at one end of an interlocking plate 28 is somewhat wobbled after it is engaged in the groove of a regulation plate 36, the visual field of the device 5 is still maintained as the L-size visual field, so that the original Lsize visual field range is prevented from being partially lacked or extended on the contrary.

Inventor: YOSHIOKA AKIFUMI
IPC: F22B1/18
Filed: 1984-01-26
Abstract: PURPOSE:To peel off the adhered matters on the heat transfer surface of the titled boiler to effectively remove the same by bringing a cement clinker burnt in the cement plant into collishion with the heat transfer surface of the recovery boiler in a waste heat recovery boiler of a suspension preheater in the cement plant. CONSTITUTION:Small particles of the cement clinker for blowing in are collected by an electric dust collector 9 at the outlet of a clinker cooler 8, and are blown into the intermediate part of an upstream gas dust 6 of an SP (suspension heater) boiler 1 by clinker blow-in blower 2 through a transport pipe 3. The small particles of the clinker have a large specific gravity as compared with particles of cement raw material, and have no adhesive property. Hence, when small clinker particles are blown from the suspension heater (SP) into dust (mainly, cement raw material power) spraying through the dust 6, dusts fixed to the surface of a boiler water pipe group is collected as if they were ground off. By blowing small clinker particles into the dusts, the heat transfer surface of the SP boiler can be cleaned, and the surface of the boiler water pipe group is smoothened. Thus, the heat transfer surface of the boiler can be constantly cleaned.

Title: Magnetic fluid seal structure
Inventor: IMAMURA TAKAHIRO
IPC: F16J15/40
Filed: 1987-01-20
Abstract: PURPOSE:To improve sealing efficiency by providing an annular magnet, two annular pole pieces disposed on opposite sides of the magnet and having inner diameters different from each other, and a stepped shaft having an outer diameter corresponding to the inner diameters, the shaft being formed in the lowered surface thereof adjacent to the unclean environment with a groove for temporarily receiving magnetic fluid therein. CONSTITUTION:A groove 7 formed in a stepped shaft 10 is preliminarily filled with a predetermined amount of magnetic fluid 4, and then the shaft 10 is inserted in the direction shown by an arrow. When the magnetic fluid 4 received in the groove 7 passes through a pole piece 9 which is apart therefrom, it will not be attracted by the pole piece 9. Thereafter, when it comes near the pole piece 8, the magnetic fluid 4 moves out of the groove 7 to be attracted by the pole piece 8, so that the whole amound of the magnetic fluid 4 is injected only into the pole piece 8, thus completing a magnetic fluid sealing. As the magnetic circuit is closed at this time, the space between the pole piece 9 and the portion opposite thereto must be small, and for this purpose, the shaft 10 is stepped. Therefore, scattering of the magnetic fluid 4 can be prevented.

Title: Method for estimating position of heat cracking
Inventor: KAMIMURA TADASHI
IPC: G01N27/82
Filed: 1995-01-30
Abstract: PURPOSE: To estimate the position of heat cracking in a base material by causing cracks in a coating layer having a magnetic characteristic by utilizing the thermal expansion and contraction of the base material after forming the coating layer on the surface of the base material. CONSTITUTION: An oxide film having a magnetic characteristic is formed as a coating layer 4 on the surface of the thermal cracking generating dangerous area 2 of an exhaust manifold 1. When the manifold 1 is fitted to an actual engine and a prescribed heat load is given to the manifold 1 for about 1 to 5 hours, fine cracks 5 are generated in a strain figure in the coating layer 4. Since the layer 4 (oxide film) in which the cracks occur is far fragile than the manifold 1 itself and the heat resistance of the layer 4 is weaker than that of the manifold 1, the cracks 5 occur in an extremely short time as compared with the crack occurring time in the manifold 1 itself. Therefore, the position of the thermal cracking of the manifold 1 itself can be estimated by detecting the cracks 5 by performing magnetic inspections.

Title: Filter circuit
Inventor: YAMASHITA NORIYUKI
IPC: H03H11/04
Filed: 1984-01-26
Abstract: PURPOSE:To change instantaneously the center frequency with an active filter whose center frequency is controlled according to the phase difference between an input and an output, by providing plural memory circuits which store the phase difference detection output and then switching those memory circuits. CONSTITUTION:The center frequency f0 of an active filter 14 is controlled so that the phase difference between the input and the output is set at 90 deg. by detecting said phase difference by a differential amplifier 21 and feeding the detection output back to an f0 control terminal through a memory circuit 26. Up/ down counters 22 and 23 of the circuit 26 count up or down the clocks CK in response to the increase or decrease of the output of the amplifier 21. A track jump signal JUMP stops the counting action of either one of both counters, and the count value is held in the counter. Therefore the signal JUMP is inverted when a rotary head crosses a track in a variable speed reproduction mode. Then the counter is switched to change the center frequency of the filter 14.
