Title: Magnetic recording medium
Inventor: YAMAURA MICHIO
IPC: G11B5/66
Filed: 1985-05-02
Abstract: PURPOSE:To obtain the titled thin film-type magnetic recording medium having a recording layer formed with the thin film of metal consisting essentially of ferromagnetic metal having excellent durability by providing a protective layer composed of cobalt oxide consisting essentially of Co3O4 having a visible prismatic structure. CONSTITUTION:A cobalt oxide consisting essentially of Co3O4 and having a visible pillar-shaped structure is used. When a magnetic recording medium is cut to form an extremely thin piece which is observed by a transmission electron microscope, the oxide can be observed as vertical stripes vertical to the layer surface on the side cross section of the oxide layer. The protective layer of cobalt oxide is formed in an oxidizing gas atmosphere by vacuum deposition, sputtering, etc., with metallic cobalt as the vaporization source of a target or by RF sputtering using powdery target by cobalt oxide such as Co3O4. For example, a metallic thin film 2 of a high-permeability nickel alloy and a vertical magnetic recording layer 3 of a cobalt-chromium alloy thin film are successively laminated on both surfaces of a substrate 1 of polyethylene terephthalate film and a protective layer 4 is further laminated thereon in an oxidizing atmosphere with metallic cobalt as the target.

Title: Gutter package
Inventor: MAKIDO TATSUO
IPC: B65D75/52
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the kinds of packaging papers by attaching to the surface of a package a sheet of paper which has a ground of almost the same color as that of a gutter with the letters indicating the gutter color marked thereon in the color different from the gutter color. CONSTITUTION:Packaging papers 3 are wrapped around gutters 1 bound in a bundle and a color indicating tape 5 is wound around the packaging papers 3 lengthwise in its center. The color indicating tape 5 has a ground 52 almost the same in color as the gutter with the letters 51 indicating the gutter color marked thereon in the color different from the gutter color, or vice versa. This permits sharing of the packing papers between the gutters 1 of different colors and hence a reduction in the kinds of the packing papers 3, thereby permitting the packaging to be simplified from the aspects of preservation and shipping control.

Title: Support structure of annular vibrator
Inventor: KURODA TATSUYA
IPC: G01C19/56
Filed: 1995-03-28
Abstract: PURPOSE: To provide the support structure of an annular vibrator, which can support the vibrator satisfactorily in such a way that its exciting motion is not disturbed and is suitable for the detection of an angular velocity. CONSTITUTION: When a piezoelectric vibrator 10 is expanded to the direction of an arrow FC, arms 49, 51 at a support 50 in the horizontal direction are displaced so as to increase their angle as indicated by a dotted line. Inversely, when the piezoelectric vibrator 10 is contracted in the direction of the arrow FC, the arms 49, 51 at the support 50 are displaced so as to decrease their angle as indicated by a one-dotted chain line. As a result, positions which are not displaced or positions in which only a very small displacement is generated in any case of expansion or contraction exist in the arms 49, 51, and supports 56, 58 in the vertical direction are coupled to the positions. Consequently, the piezoelectric vibrator 10 can be supported in such a way that its expansion and contraction and exciting motion is not disturbed, and an angular velocity can be detected satisfactorily.

Title: Train-operation control-command transmitter
Inventor: HONMA EIJU
IPC: B60L15/20
Filed: 1990-04-10
Abstract: PURPOSE:To monitor the generation of trouble at all times regardless of the presence of the starting of each motorman's seat by inputting the starting commands of the motorman's seats, turning an output from a modulation circuit ON-OFF and outputting the contact of a transmission effective relay as the trouble of a train-operation control-command transmitter. CONSTITUTION:A frequency-modulated signal and the ON/OFF commands of a modulation circuit corresponding to a motorman's-seat starting command input from a terminal B are input to a switch circuit (35). On the other hand, an excitation-signal output circuit 4 conducts the AND logic output of the excitation signal of a first system circuit 1 and the excitation signal of a second system circuit 2. That is, the output is generated only when both signals are generated. The excitation signals are amplified or rectified after amplification by an AC amplifier 5, and a transmission effective relay coil 6 is excited. When the excitation of an input signal is stopped, output power is lost because only an AC section is amplified, and the transmission effective relay coil 6 is demagnetized. The stoppage of the excitation signals is output to the outside by a relay contact 28 driven by the transmission effective relay coil 6 at the same time.
