Title: Anchor for member fixture
Inventor: OSADA YOSHIMASA
IPC: F16B15/00
Filed: 1993-05-23
Abstract: PURPOSE:To prevent destruction of a driving layer by bending outward each end of a wire in inverted U form. CONSTITUTION:A rod-shaped anchor member 4 is interposed between the bottom of a shaft 2 and over a crest part 1d, wherein the bottom of the anchor member 4 confronts a hole 1c provided in an outer cylinder 1. The anchor member 4 is made from a round metal wire of steel and bent in inverted U form, and the ends 4a of the metal wire are laid down and bent as confronting the inside of the hole 1c. When the head 2b of the shaft 2 is driven by hammer, the outer cylinder 1 and shaft 2 are consolidated by a spacer 6, and the outer cylinder 1 is driven till a flange 1b to stop there. With another strike, the outer cylinder 1 is stopped moving by the flange 1b and compressed by the head of the shaft 2, and the spacer cylinder 6 is split and segregated. With a subsequent strike, attachment of adhesive 3 is released, and the shaft head 2b is driven to the surface of the flange 1b. At this time, the anchor member 4 emerges out of the hole 1c and intrudes into the underlay layer B without destruction of the layer, and thus anchor is achieved.

Title: Heat exchanger tube and its manufacture
Inventor: KASE HIROAKI
IPC: B23K1/00
Filed: 1988-06-10
Abstract: PURPOSE:To improve the heat transfer rate of a fluid of the inside of a tube by thinning a temperature boundary layer by constituting plural passages of a flat tube provided with plural projections on the inside surface of the tube. CONSTITUTION:In a heat exchanger tube 11, a flat tube 15 having a short side 15a and a long side 15b is further flattened by bringing the long side 15b to press-contacting by a roll machine. Also, projections extended from the inside surface of one long side 15b of the flat tube 15 to the other long side 15b side are constituted as one body. Also, a brazing filler metal 16 adheres to the inside surface of the flat tube 15. By bringing the flat tube 15 to press-contacting by the roll machine, the tip of the projection 13 abuts on the inner wall of the long side 15b of the opposite side. Subsequently, by putting the flat tube 15 into a heating furnace and melting the brazing filler metal 16 adhering to the inner wall surface of the flat tube 15, the projection 13 and the inner wall surface are joined. As a result, as for the heat exchanger tube 11, length (a) in the short side direction is comparatively small, and also, many passages 12 of a fluid which passes through the inside of the tube are formed.

IPC: H03H9/10
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric device for surface mount which is mounted in a stable state without enlarging the element. SOLUTION: A lead terminal 16 extended onto a base 14 is passed through a hole 22 on an insulator 21. Without folding this lead terminal 16, a terminal 24 for surface mount composed of a metal piece in the shape of thin plate is connected. Thus, any mechanical strength is not required for the insulator 21 on the bottom face of the base 14 at the time of production. Further, this insulator 21 is composed of a resin film or a thin layer resin plate suitable for thinning a product. Therefore, the heightwise direction of the element is suppressed low. Additionally, the bottom face of the terminal 24 for surface mount is almost flat and at the time of mounting onto a printed circuit board, etc., stability is made satisfactory as well.

Title: Magnetic head
Inventor: SANO SHINYA
IPC: G11B5/17
Filed: 1984-07-13
Abstract: PURPOSE:To obtain the optimum gap width in both recording and reproducing modes by adhering a magnetic material having lower density than the saturated magnetic flux density of a core to the gap counter surface of the core. CONSTITUTION:A magnetic material 9 having the saturated magnetic flux density lower than that of a core 7 is adhered to the counter surface of a gap 4 of the core 7. When a comparatively large current is flowed in a recording mode, the area near the gap 4 is saturated first. The permeability of the material 9 is reduced with a current larger than said level. This increases the effective gap width, and the lines of magnetic force are concentrated on a gap edge part. Then a tape magnetic body 5b is magnetized to ensure the satisfactory recording up to a short wavelength area. In a reproducing mode a magnetic field reaching a head from the body 5b is extremely weak and therefore a magnetic material 6 is not saturated. This prevents the increase of the gap width and furthermore secures the reproduction up to a short wavelength area. Thus the optimum effective gap width is secured in both the recording and reproducing modes. This ensures the effective recording/reproducing up to a short wavelength area.
