Title: Drilling method and device therefor
Inventor: TERABAYASHI TAKAO
IPC: B23B47/24
Filed: 1986-01-13
Abstract: PURPOSE:To make it possible to foresee breakage of a small diameter drill caused by an abrupt increase in cutting torque during drilling a small diameter hole, by detecting a rotational phase difference between a chuck and a spindle which is generated during the drilling. CONSTITUTION:A drilling device has a magnetic coupling 4 coupling between a collect chuck 2 and a spindle 5. Accordingly, if chips are jammed during drilling and therefore cutting torque is increased, the rotational phase difference between the chuck 2 and the spindle 5 is increased associated with a slip in the magnetic coupling 4. Further at the moment of the rotational phase difference exceeding a preset threshold, an evaluating device 16 delivers a drill 1 breakage warning signal to a drilling depth control device 17, and therefore, a motor 12 provided with an electromagnetic brake is stopped to stop the drilling. Further, the motor is reversed to retract the drill 1 from a workpiece so that the chips are discharged. Thereafter, the motor 12 is normally rotated to drill the workpiece again.

Title: Device for conveying refuse
Inventor: MARUO SHIYOUZOU
IPC: B65G25/10
Filed: 1978-01-17
Abstract: PURPOSE: To convey and collect refuse under dust chute in a building to one plate  by reciprocatingly moving refuse urging member in a trough disposed with a plurality of scrapers for preventing the refuse from reversely returning.  
     CONSTITUTION: Refuse thrown through an inlet 4 into a dust chute 3 is dropped to be supplied into a trough 2. When hydraulic cylinders 12, 14 are telescoped back and forth, a refuse pushing member 6 is moved forwardly to urge the refuse. Upper and lower scrapers 16, 17 are urged forwardly upon movement of the refuse in this case to be thus rotated. When the member 6 starts forwarding at 2 pitches, it will then retard. Both the scrapers 16, 17 are lowered vertically at that time to cause the forwarded refuse to stop at the front of the scrapers 16, 17. As the member 6 is retarded, the lower scraper 7 slidably makes contact sequentiall with the  oblique surface 6c and horizontal surface 6b to prevent the refuse from reversely returning. When the above operations are repeated, the refuse is forwarded at every 2 pitches to be thus conveyed so as to discharge the refuse from an outlet 5.

Title: Method for positioning leg of washing-space waterproofing pan
Inventor: ARAI KAZUMA
IPC: E03C1/20
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a positioning method for the legs of a washing-space waterproofing pan, not requiring a jig for positioning, and making it easier to detect positional deviation of the legs before fixing. SOLUTION: A reinforcing plate 12 is provided on the back of a washing- space waterproofing pan 1 and locking pieces 622 provided at leg fixing parts 621 are made to abut the corners of the reinforcing plate 12 so as to position legs 6. A jig for positioning the legs 6 is thus unnecessary. Further, positional deviation of the legs 6 before fixing leads to formation of a gap between the corners of the reinforcing plate 12 and the locking pieces 622, and therefore the positional deviation of the legs 6 is easy to detect.

Title: Production of niti shape memory alloy coil spring
Inventor: SAWADA KAZUO
IPC: F16F1/04
Filed: 1985-01-14
Abstract: PURPOSE:To obtain a coil spring having an excellent electrical insulating characteristic, chemical resistance and corrosion resistance by coating a fluororesin on a wire consisting of an NiTi shape memory alloy then forming the wire to a coil shape. CONSTITUTION:The wire 1 which consists of the NiTi shape memory alloy and is cut to a prescribed length passes through the inside of a cylindrical die 2 at the central axis thereof. The heated and softened fluororesin 3 is packed in the die 3 and is extruded under the pressure, by which the coating layer for the wire 1 is formed. The coated wire passes between a guide roller 4 and a press roller 5 and is wound on a mandrel 6, by which the wire is formed to the coil shape. The coil is thereafter treated to memorize the shape to the prescribed shape. Such coil spring has much wider use environment than for the coil spring without the coating layer and the electric resistance value does not decrease even if the winding parts of the coil contact tightly with each other and therefore the coil is immediately heated when conducted with electricity. The coil has the sharp responsiveness.

Filed: 1994-01-24
Abstract: PURPOSE:To lessen the influence of eddy current and to improve the frequency characteristics by electrically conducting magnetic cores disposed to face each other via nonmagnetic gap films through a resistance film having a prescribed resistance value. CONSTITUTION:This ring type magnetic head is constructed by clamping the magnetic cores 1 laminated with magnetic metallic films 6 and insulating films 7 with nonmagnetic substrates 2 from both ides. The magnetic cores 1 disposed to face each other via the nonmagnetic gap films are electrically conducted through the resistance film 5 of 50 to 10<9>OMEGA/square. The noise by the discharge between the magnetic head core 1 is prevented as by suppressing accumulation of charges up to a discharge potential by connection of both cores 1 and 1 with the resistance of <=10<9>OMEGA. On the other hand, the flowing eddy currents are made slighter than in the case of use of ordinary metallic films having a high electrical conductivity by setting the sheet resistance of the films connecting both cores 1 at >=50OMEGA. The generation of the significant influence on the magnetic characteristics is averted and the good head characteristics are obtd.
