Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To restrain internal pressure increase at charging and discharging capacity reduction at high rate discharging by covering carbon fiber for constituting an electrode with a nickel metal layer together with hydrogen storage alloy particles and a binding agent. SOLUTION: A hydrogen storage alloy electrode for an alkaline storage battery is composed of carbon fibers covered with hydrogen storage alloy particles, a binding agent and a nickel metal layer. In the carbon fiber covered with the nickel metal layer, an added quantity is desirably 0.05 to 10.0 pts.wt. to 100 pts.wt. the hydrogen storage alloy particle, the thickness of the nickel metal layer is 0.05 to 1.0 μm, the end part is not covered with the nickel metal layer, and the surface of the carbon fiber is exposed. Electric resistance of an alloy electrode can be reduced by reducing contact resistance of the alloy particles and the carbon fiber to enhance discharging capacity at high rate discharging.  Since nickel metal on the surface of the carbon fiber is low in hydrogen overvoltage, hydrogen dissociation is restrained by the surface of the alloy particles to restrain the internal pressure increase.

Title: Tip saw
Inventor: BABA KOICHI
IPC: B27B33/08
Filed: 1994-10-03
Abstract: PURPOSE: To obtain a tip saw which has an undetachable cemented carbide tip and a hardly fissuring blade plate by forming an engagement recessed part for the cemented carbide tip provided on the outer peripheral part of a blade in a nonrectangleshape having an expanded innermost corner, and mounting the cemented carbide tip with a base which can engage with the recessed part tightly, in the recessed part. CONSTITUTION: A blade plate is of a circular metal plate with recessed parts 13 formed intermittently at a constant interval on the outer peripheral part. The recessed part 13 has the larger width (b) of an innermost part than the width (a) of an entrance part. In addition, the recessed part has a warped shape which is symmetrical at right and at left and is nonrectangular like an ellipsoid. Further, a cemented carbide tip with a blade part, the front and rear of which have mutually different physical properties, is forced into the recessed part 13 through the front side of the blade plate to achieve their tight engagement. After the engagement, the cemented carbide tip 2 is brazed to the blade plate.  In this case, a fused brazing metal finds its way into a gap between the recessed part 13 and the base part 21 of the cemented carbide tip 2 by capillarity and becomes hardened to increase the brazing strength because of the narrow gap. The recessed part 13 is of such a shape that its innermost part is expanded and no angular part is present. Therefore, the cemented carbide tip 2 does not become detached, if it is given an impact to some extent. Besides, no fissure hardly generates on the blade plate.

Filed: 1984-12-18
Abstract: PURPOSE:To simplify the circuit constitution of the input stage by discriminating a high-order bit through the generation of a reference potential and a low-order bit through a voltage subject to level shift for an input analog signal. CONSTITUTION:The analog signal inputted to a terminal 1 is subject to level shift by the 1st series resistor group 3. Each terminal voltage subject to level shift is inputted to emitter followers 4, 5, 6, 7. On the other hand, a high-order 2-bit reference voltage is generated by the 2nd series resistor group and outputted via emitter followers 10, 11, 12, 13. The high-order 2-bit is obtained by comparing voltages of each emitter follower output of the high-order bits and the low-order bits obtained in this way, that is, outputs of comparators 18d, 18h, 18. Further, an output obtained as the result of discrimination of the further 1/4 division of the lowest level of the input dynamic range subject to 1/4 division is obtained from comparators 18a-18c.
