Title: Manufacture of metal plate covered with resin film for welded can
Inventor: ZEN KANMOKU
IPC: B29C63/02
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the waste of a metal at an unnecessary part, and suppress the discharging of a harmful substance which is produced in coating and printing processes by a method wherein a band-shaped resin film is coated on parts excepting welding parts at the time of manufacture of a welded can, on one surface or both surfaces of a stock roll for plating or a cold drawn steel plate. SOLUTION: Instead of coating a resin film after performing a plating in order to improve the weldability and corrosion resistance on the whole surface of a metal plate, a resin film 2 is coated on remaining parts excepting welded parts at the time of manufacture of a welded can. For the metal plate 1, a stock roll for tin plating or a cold drawn steel plate is used as is without a pre-treatment, or in order to improve the joining force, a degreasing and a washing with acid are performed. However, when the bonding condition is change depending on the kind of the resin film and the presence of the application of an adhesive, before the resin film is coated, a chemical conversion treatment film 4 such as a chromate film or a phosphate film is formed by an electrical or chemical method, and then, the resin film 2 is coated.

Title: Laser range finder
Inventor: HOSOKAWA TETSUO
IPC: G01S17/02
Filed: 1991-12-06
Abstract: PURPOSE:To prevent the saturation of a detector and keep reflected light from getting out of a visual field at the time of measuring short distance by reflecting a very small part of light emitted from a laser oscillator, and bringing this reflected light in line with a receiving optical axis. CONSTITUTION:The light from a laser oscillator 1 is made parallel by a collimator lens 21 and then emitted outside through a semi-transparent mirror 23 (transmitted light P). At this time, only a small part of light is reflected and proceeds for a semi-transparent mirror 24 placed on a light receiving axis. At the semi- transparent mirror 24, a part is reflected again and proceeds in the direction coinciding with a light receiving axis (reflected light Q). The transmitted light P generally goes not parallel with the optical axis of a lens 22 and enters a receiving angle of visibility only after going in a certain distance. On the other hand, the reflected light Q proceeds in the direction coinciding completely with the light receiving axis. Accordingly, however even if there is an object at any close point, the light reflected from the object can be detected (3) to be in the receiving angle of visibility theta.

Filed: 1989-12-15
Abstract: PURPOSE:To perform switching depending upon external force by generating pulse signals in such a manner that a pulse generating element is relatively displaced between the first and the second magnetic field generating means. CONSTITUTION:A Wiegand element 10 is firmly mounted on the tip of a supporting piece 25 which is fixed on the side wall of a case 1. A magnetic unit 13 has two permanent magnets 11, 12 connected with a connection portion 15 in parallel. When a push button 20 is depressed to move the magnetic unit 13 downward, magnetic force applied to the Wiegand element 10 is changed from that derived from the permanent magnet 12 into that derived from the permanent magnet 11. When there is no depression of the push button 20 which is then released from external force, the magnetic unit 13 is set back to an original position to reverse magnetic field applied to the Wiegand element 10. It is thus possible to displace a magnetic distortion pulse generating element relatively depending upon external force, output pulse signals and switch an electric circuit.

Title: Detecting device of water level
Inventor: NAKAMURA SHOJI
IPC: G01F23/16
Filed: 1988-12-22
Abstract: PURPOSE:To reduce the cost by a method wherein a ceramic thin plate having a deflection characteristic of hysteresis approximate to zero is used as an elastic diaphragm. CONSTITUTION:An elastic diaphragm 8 of a thin plate made of ceramic is fixed to a housing 7 by a bonding agent 9. In the upper part of the housing 7, the upper end of a columnar tube 10 opens to the air and silicon oil is filled up as an incompressible fluid 13 in a space 12 and up to the middle of the columnar tube 10. When the diaphragm 8 is displaced from a connection port 16 by the water level of a bathtub, the pressure becomes positive or negative according to the relationship in a set position between the bathtub and a water level detecting device. When the pressure is positive, the capacity of the space 12 lessens and the liquid level of the fluid 13 rises, while the liquid level of the fluid 13 lowers when the pressure is negative. This displacement of the water level is detected as a liquid level change signal by a detecting means 14 and an output of the means 14 is converted into an electric signal by a controller 15. By this constitution, the cost can be reduced.
