Title: Difference-in-level recognizing member
Inventor: FUKUI YASUKI
IPC: E04F11/16
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To prevent the tumbling or falling accident by the slippage in a stairway of an aged person by arranging, on the front end part of a tread, a difference-in-level recognizing member having irregularities on the surface so that the brightness difference between the recessed part and the tread is set within the range of a prescribed value. SOLUTION: A recognizing part 2 having a brightness difference with the color of a tread 5 of 2.0-4.0 and a width of 4mm or more is arranged within the recessed part 4 of a vinyl chloride resin-made difference in level recognizing member 1 having a protruding part 3. The recognizing part 2 may be divided into a plurality of pieces so as to have the total width of 4mm or more. The difference-in-level recognizing member 1 is arranged on the front end part of the tread 5 formed of a plywood core material, a protruding plate stuck to its surface, and urethane applied thereto to prevent slippage. Thus, the recognizing part 2 can be recognized when seen obliquely from the upper part in the same manner as going upstairs and downstairs, but not observed near substantially the horizontal state, so that a sense of incompatibility can be reduced.  Thus, an aged person can easily recognize a difference in level, and the tumbling and falling accident by slippage can be prevented.

Title: Constant current control circuit
Inventor: SATO MASASHI
IPC: G05F1/10
Filed: 1985-08-12
Abstract: PURPOSE:To attain the constant current control with an alternating current by providing a load current detector, an effective value converting circuit and a comparator. CONSTITUTION:An output current IOUT is detected out of a current detector 8 and then converted into the DC voltage Vitheta by an effective value converting circuit 9 with integration held. The voltage Vitheta is compared with the constant current reference voltage Vii supplied to a comparator 10 from outside. Then the phase control voltage VIN applied to a phase control circuit 4 is corrected for execution of the constant current control. In such a condition, the circuit 9 can use an effective value detecting IC and at the same time the integration can be held. Thus, the phase control is possible with an AC constant current circuit. The number of component parts can be reduced compared with other types of power supplies with reduction attained with the weight, the capacity, etc.
