Title: Inspection of penetration depth of chromized steel pipe
Inventor: IKEDA MASAMI
IPC: G01B7/00
Filed: 1984-03-30
Abstract: PURPOSE:To enable non-destructive and quick measurement of the pipe bodies to be inspected for the total number over the entire length by applying an eddy current testing method to detect the potential difference from a reference pipe body of which the penetration depth of a chromized steel pipe is known. CONSTITUTION:A bridge circuit BRG is constituted of coils L1, L2 wound on a bakelite bobbin 1 and elements B1, B2 for balance adjustment and AC is supplied thereto from an oscillator OSC. A coil L1 is first inserted onto a reference pipe body PS1 which is the same in outside diameter and wall thickness as the pipe body to be inspected and is not subjected to a chromizing treatment (penetration depth 0) and a coil L2 is inserted onto another reference pipe body PS2. The oscillator OSC is started and the circuit BRG is balanced by the elements B1, B2. The coil L2 is then removed from the body PS2 and is inserted onto the pipe body PT to be inspected while the coil L1 is held intact. Unbalanced potential is induced in the circuit BRG when AC is conducted to the coils L1, L2 in order to induce eddy current on the surfaces of both pipe bodies. The penetration depth of the chromized layer on the surface of the pipe body to be inspected is then discriminated from the detected unbalance potential.

IPC: H01M8/04
Filed: 1987-03-17
Abstract: PURPOSE:To make a load temperature rise from low temperature performable as well as to aim at the shortening of starting time for a cell, by housing each adsorbent of moisture and carbon monoxide stratifyingly in a feed manifold of the fuel gas made up of reforming methanol into hydrogen rich gas with a reformer.

Abstract: PURPOSE:To reduce the size and the weight of the whole by connecting an oscillator, a switching element having a parallel resonance circuit, a rectifying and smoothing circuit, a switching regulator, and a rectifying and smoothing circuit in series in this order. CONSTITUTION:The output of an oscillator 11 is connected to the base of a transistor TR forming a switching element 12 through a coupling capacitor Cc, and the collector of the transistor TR is connected to a DC power source DV through a parallel resonance circuit consisting of a capacitor C and a coil L. And high-voltage oscillating voltage is generated between both terminals of the capacitor C and the coil L in accordance with the Q value of the parallel resonance circuit, since it becomes possible to perform the on-off control of the transistor TR in accordance with the output of the oscillator 11 when the oscillator 11 is operated. Incidentally, it is possible for a rectifying and smoothing circuit 13 to rectify the oscillating voltage and supply it to a switching regulator 14, since the frequency of the oscillating voltage coincides with the oscillation frequency of the oscillator 11. Accordingly, it becomes possible to reduce the size and the weight of the whole since no transformer is used at all.
