Title: Corrosion-proof device for hot water tank
Inventor: FUJISHIMA MICHIYUKI
IPC: F24H1/20
Filed: 1985-02-19
Abstract: PURPOSE:To enable a prevention of accident of making holes by a method wherein an upper part of a tank is provided with a corrosion detecting electrode and when water is flowed into the inside part of the electrode, an alarm is produced. CONSTITUTION:When an enamelled part of a tank 1 of steel plate has a minute volume of melting as the time is elapsed and the pin holes are increased in their sized, a current density in the steel protective pipe 9 for the corrosion detecting electrode 5 arranged at the upper part is initially decreased and reduced below the desired corrosion current density and then the corrosion is started to occur. If a wall thickness of the steel protective pie 9 is made thinner than that of the steel plate tank 1, the steel protective pie 9 shows at first a pin hole and water is flowed into the pipe at first. As a result, electric current is flowed between the water sensor lie 8 and the steel tank 1, a contact point of a relay 7 is operated to drive an alarm device 6 and so the accident of water leakage can be prevented.

IPC: B23Q11/10
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To sufficiently cool a cutter and discharge chips in a cut hole or cut groove by providing a cutter cooling cold air discharge port for blowing the cold air from a cutter cooling cold air intake part obliquely down toward the tangent direction of the circumference of the edge part of a cutter. SOLUTION: The cutter cooling cold air flowing into a cutter cooling cold air intake part is blown out substantially obliquely 30 deg.-60 deg. downward from the cutter cooling cold air discharge ports 18a, 18b of a cutter cooling cold air discharge ring 18. The cutter cooling cold air 26 is partially collided with the shaft part 4a of a cutter 4 to cool it, and also cools the conducted heat transmitted from a cutter driving part to the edge part 4b of the cutter 4 to prevent the heating of the cutter 4 resulted from the conducted heat from the cutter driving part. The residue of the cutter cooling cold air 26 collides with the edge part 4b of the cutter 4 to cool it, and also removes the burr of a cut hole or cut groove 29.

Title: Attraction magnet
Inventor: KUSAKA YOSHIHIKO
IPC: H01F7/02
Filed: 1994-02-02
Abstract: PURPOSE:To suppress the damage of a magnetic record even though a magnetic recording medium contacts an attraction surface by restricting a lateral slip and making easier to grasp and take said medium by covering outer peripheral edge portions of a flat plate-shaped permanent magnet piece magnetized in a thickness direction covered with rubber or a synthetic resin having a large coefficient of friction. CONSTITUTION:An attraction magnet is obtained by inserting an anisotropic ferrite magnet 1 to a colored rubber 2 formed to an inner recess. Or an elastic non-magnetic material such as a soft urethane resin or the like that can be formed by injection molding is formed to one united body with a ferrite magnet by using injection molding machine. By doing this, an attraction magnet can be obtained, which has a simple construction, does not cause lateral slip during use, can be easily grasped by fingers for removing, and does not damage a magnetic recording function when a magnetic recording medium contacts an attraction surface.

Title: Original point resetting method
Inventor: OKANO AKIHIKO
IPC: G05B19/18
Filed: 1990-02-09
Abstract: PURPOSE:To reset a machine movable axis to an original point in an unmanned environment by judging the coincidence or discordance between the original point resetting direction and the direction moving to an intermediate point from a stored coordinate position and performing the shift control of the machine movable axis so as to make this axis pass through the intermediate point. CONSTITUTION:A coordinate position which is moved to the upstream side of the original point resetting direction 2 from a coordinate position of an original deceleration dog switch 7 by a distance larger than the moved distance of a machine movable axis set in a period covering the cut-off of the power supply of a numerical controller through the next application of the power supply is set as an intermediate point 3. The coordinate position of the machine movable axis set at cut-off of the power supply of the numerical controller is stored and the coincidence or discordance is judged between the direction 2 and the direction moving to the point 3 from the coordinate position stored in response to the application of the power supply of the numerical controller. If the coincidence is secured between both directions, the machine movable axis is directly moved to the direction 2. If not, the movable axis is moved to the point 3 and then to the direction 2. Thus the machine movable axis can be automatically reset to its original point after application of the power supply with no operation required for an operator.

Title: Solid state image device
Inventor: IKEDA SHIGEO
IPC: H04N5/335
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To enable simply ensuring position accuracy in the direction of optical axis and minimize the work in a clean room, by cutting off a solid state image device from the outside by mounting a lens thereon. SOLUTION: First, in a clean room, a CCD chip 7 and a lens 8 of a solid state image device 1 are mounted on positioning portions 4 and 5 of a supporting member 2, respectively. Next, in a normal environment outside the clean room, an infrared filter 15 is adhered to a diaphragm plate 9, which is then mounted on a diaphragm plate positioning portion 6 of the supporting member 2. Therefore, simply by mounting the solid state image sensing device 7, the lens 8, the filter 15 and the diaphragm plate 9 on the single supporting member 2, the positional relation of these elements may be accurately regulated. Thus, no error is generated in the mounting position by the quantity or type of an adhesive, and a solid state image device having uniform quality with no irregularity may be produced.  Also, since the device 1 is cut off from the outside after the lens is mounted, there is no risk of intrusion of dusts.
