Title: Mesh fence
Inventor: KIKUZAWA TETSUJI
IPC: E04H17/16
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To improve a function by providing a wire material before and behind and horizontally on the upper end of a mesh panel spanned between supports, and bending both ends thereof upward to make a part to mount a flowerpot. SOLUTION: A pair of mesh panels 2 are attached through a panel attaching fitting 3 to front and rear face of a support 1 erected at a prescribed interval. Next, the panel 2 is formed by vertically and horizontally intersecting steel wires to be arranged in the form of a lattice, and the intersection point of the steel wires is fixed by resistance welding or the like into a lattice. Next, the upper end of the panel 2 is folded substantially at a right angle to provide a horizontal part 23, and furthermore the horizontal part 23 is folded in substantially parallel with the panel 2 to form a locking part 24. A flowerpot, a planter 4 or the like is mounted on a gutter mounting part 25 formed of the horizontal part 23 and the locking part 24, and falling of the flowerpot, the planter 4 or the like is prevented. Thereby a couple of forces does not act on a mesh panel, even when a large-sized planter is mounted thereon, deflection of the mesh panel can be reduced, and a planting can be locked at from the surface and rear of the mesh fence.

Abstract: PURPOSE:To produce a copper product forming a homogeneous patina film on the whole surface in an early stage by allowing a potentially noble substance nobler than copper or copper alloy to adhere to the surface of a copper product consisting of copper or copper alloy by means of displacement plating, electroplating, etc. CONSTITUTION:A potentially noble substance nobler than copper or copper alloy is allowed to adhere to the surface of a copper product in which at least the surface is composed of copper or copper alloy. As the above potentially noble substance, one or more elements among Ag, Au, C, and platinum group elements are preferred. Further, it is preferable to regulate coating weight to 1-1000mg/m<2>.

Title: Peak amplitude detector
Inventor: TOOMASU EMU UOORII
IPC: G01R19/04
Filed: 1994-01-27
Abstract: PURPOSE: To reduce necessary power and control the step down of charge by providing a peak memory capacitor to be integrated into the chip of a detector. CONSTITUTION: The voltage from a memory capacitor 150 is returned to the negative input 106 of a comparator 120 in order to compare it with an input signal 102. When the input signal 102 exceeds a voltage stored in 150, a transfer gate 130 is ON by the comparator 120 to store a new amplitude in the capacitor 150, and when the signal 102 is less than the newly stored amplitude, the gate 130 is OFF. The capacitor 150 is integrated into a chip, whereby not only all elements of a peak detector can be integrated into one chip, but also the power necessary for the operation of the circuit is minimized because CMOS technology is utilized, and a power source of 5V suffices for it. Further, an active filter having a gain of 1 is provided as a delay buffer 110, whereby the detection precision to the extremely high speed input signal 102 is enhanced.
