Title: Hand rail support bracket
Inventor: MINAMIURA YOSHIYUKI
IPC: E04F11/18
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To facilitate execution of a hand rail and contrive stability support by supporting a cylindrical hand rail support ring by integrally fixing it with the screw seat of a wall face and fitting the hand rail in a fitting hole, and making a stopper for preventing penetration of the hand rail to the fitting hole. SOLUTION: The fitting hole 41 of a hand rail support ring 4 is made by reducing diameter size from each opening to the center part and making it slender toward the interior, and a stopper 42 is disposed in the inner periphery of the fitting hole 41. At the time, a diameter minimum part 43 is formed in the center part of the axial direction of the fitting hole 41. The diameter size of the interior narrowness of the hand rail support ring 4 is matched to the diameter size of a hand rail T, which does not penetrate the fitting hole 41, and each diameter size of the diameter minimum part 43 and a hole opening part are set. At the time of execution of the hand rail T, penetration for the fitting hole of the hand rail T is prevented, a mounting state is stabilized, and hand rail execution is facilitated at a site.  Even if unevenness occurs on the diameter size of the hand rail T, unevenness is absorbed by the stopper 42. Thereby the support state of the hand rail T by a support bracket 1 can be stabilized.

Title: Heating of electrochemical cell
Inventor: MASE SHUNZO
IPC: G01N27/419
Filed: 1989-12-04
Abstract: PURPOSE:To enable a higher reliability by allowing a heater leak current to flow into an electrode exposed to a gas containing air or oxygen to prevent breaking of ceramics adjacent to a negative pole. CONSTITUTION:A gas to be measured reaches the surface of an electrode 2 passing through an opening 14 of a housing 13 and an opening 16 of a heat insulating cylinder 5. Air as reference gas reaches the surface of an electrode 5 as reference electrode passing through a vent hole 18 of a cap 17 and a hole 20 of an insulating body 19. When a DC power source 26 is connected through a terminal section 11, a heater 10 generates heat to heat up solid electrolyte layers 1, 3 and 4 and ceramic layers 8, 9 and 12. The layers 8 and 9 come to present an electroconductivity with a rise in temperature. Under such a condition, a part of a DC current applied to the heater 10 flows very slightly through the layers 8 and 9 as leakage current. But the electrode 2 exposed to the gas to be measured is connected to a negative pole of the DC power source 26 to make potentials of the both equal. Thus, the leakage current can be escaped to the electrode 2, not to the negative pole of the heater thereby eliminating effect thereof on an electrochemical cell.
