Title: Operation change-over device
Inventor: HANAJIMA MITSURU
IPC: G11B15/02
Filed: 1977-09-14
Abstract: PURPOSE: To selectively move a pinch roller by keeping two gears from meshing with each other when a motor is stopped.  
     CONSTITUTION: When a stop switch 14 is turned on, a motor starts its rotations at a high speed. under this condition, if a main switch 10 is turned off, the motor 1 is rotating at a high speed so that without any power supply to the motor 1 gears 3 and 4 continue their rotations due to the inertia unti the gear 4 is stopped by the pawl of a stopper 15 at its tooth-removed portion. Even if the main switch 10 is turned off but a reproduction switch 13 is turned on, an electromagnetic coil 7 is left denergized. As a result, the gear 4 is kept retained by the action of the stopper 15 so that the motor 1 can be prevented from being stopped while having the gears 3 and 4 meshing with each other.

IPC: E04B1/64
Filed: 1992-04-28
Abstract: PURPOSE:To raise the efficiency of operation by a method in which the area between the upper outer wall and the lower outer wall which are set vertically is objected to a waterproofing treatment using a water drain sheet having a plastically deformable core material. CONSTITUTION:A wafer drain sheet 30 with a metal wire 40 as a core material is attached to the area between an upper outer wall 10 and a lower outer wall 50 which are set vertically. The sheet 30 is formed of a flexible material such as vinyl chloride sheet, and the upper end of the surface side of the sheet 30 is attached horizontally to the lower end of the back side of the upper outer wall 10. The temporary fixing operation of the water drain sheet can thus be simplified.

Abstract: PURPOSE:To prevent deviation in the adjustment state of an optical path and to accurately read the picture of a writing medium even if distortion occurs in a case by means of an external force by fixing a frame holding a light source, a reflecting plate, a converging part and an image sensor inside the case. CONSTITUTION:If a motor 12 is driven, rollers 14 and 15 are rotated and the writing medium 13 is rotated when the picture on the writing medium 13 is printed, the picture illuminated by a fluorescent lamp 25 is reflected by a mirror 29, is converged by a wide angle lens 35 and read by the image sensor 36, whereby the read data is printed by a printer 18. The case 1 has a flat shape and its rigidity is insufficient. On the other hand, the fluorescent lamp 25, the mirror 29, the convergence part 32 and the image sensor 36 are held by the frame of high regidity. Thus, deviation in the precision of picture reading can effectively be prevented.

IPC: G03B7/097
Filed: 1984-05-30
Abstract: PURPOSE:To obtain proper exposure by reversing a stepping motor when the time corresponding to the quantity of interpolation accumulates after a final step driving pulse is outputted during shutter release operation. CONSTITUTION:When a shutter release button is depressed, a switch 24 turns on to put a subject brightness detecting circuit 23 in operation, and an exposure data storage circuit 27 outputs the number of steps of the motor and the quantity of interpolation to a rotation mode changeover counter circuit 29 and presets them. If the shutter release button is pressed in to the 2nd position after the exposure is set, a switch 32 turns on to put a driving pulse generating circuit 28 in operation, and the stepping motor 12 begins to open a sector. When the 1st counter 29a counts down to zero, a clock for interpolation is inputted from a gate G3 to the 2nd down counter 29b. When clocks as many as the preset number of the 2nd counter 29b are inputted, a forward/backward switching circuit 30 is inverted to set a motor driving circuit 31 to the reverse driving side, and the stepping motor reverses to close the sector.

IPC: F28F19/06
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To enhance corrosion resistance of an aluminum brazing sheet member by adding a specified quantity of Cu to an aluminum alloy fin material being combined with the brazing sheet member employing an aluminum alloy containing specified quantity of Cu as a core material. SOLUTION: Core material of a brazing sheet made of an aluminum alloy containing 0.1-1.0 wt.% of Cu inevitably. Cu is added in order to provide a sacrifice anti-corrosion layer on the brazing material side by rendering the potential of the core material noble while enhancing the strength. The effect is low when the content is lower than a lower limit and corrosion resistance is lowered when an upper limit is exceeded. An aluminum alloy fin material being brazed in combination with the brazing sheet contains 0.3-1.0 wt.% of, Cu in order to suppress reduction of Cu by diffusing Cu to the core material side at the time of brazing. Diffusion of Cu is insufficient when the content is lower than a lower limit and when an upper limit is exceeded, not only the diffusion effect of Cu is invariant but also the sell corrosion resistance of the fin material is damaged significantly.

Title: Inhibitor of corrosion or the like in metal surface and method for inhibiting corrosion or the like
Inventor: FUKUSHIMA TOSHIRO
IPC: C23F11/00
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit corrosion or corrosion cracking in the surface of a metal from occurring by using a blend of an organic or inorganic coating film forming material and grainy titanium dioxide as a corrosion inhibitor. SOLUTION: In the method using this inhibitor 1, grainy titanium dioxide is adopted on account of its good corrosion resistance and corrosion cracking resistance and the surface of a base material K made of a metal or the like is coated with the inhibitor 1 to form a coating layer of the inhibitor 1 on the surface of the base material K. At this time, a film forming material 3 is interposed between every adjacent two of grains 2 of the titanium dioxide so that every adjacent two of the grains 2 are not joined to each other and each of the grains 2 is disposed at a position independent from the other to form the coating layer of the inhibitor 1.  Therefore, when a change in temp. is caused, each of the grains 2 is expanded or contracted independently from the change in volume of the base material K to prevent any swelling or cracking of the coating layer of the inhibitor 1 due to the difference in thermal expansion coefficient between the base material K and each of the grains 2 from occurring. If there is any recessed part K1 in the surface of the base material K, the recessed part K1 can be filled with the inhibitor 1 by a coating or injection method. The coating of the surface of the base material K with the inhibitor 1 can more easily be performed in a shorter time as compared with a conventional thermal spraying process or the like.  Thus, any recessed part in a state subjected to pitting corrosion such as sulfide corrosion can easily and surely be filled with the inhibitor 1, and accordingly, an equipment in a state subjected to pitting corrosion can be repaired with the inhibitor 1.
