Title: Guidance broadcaster for elevator car
Inventor: YAMAGUCHI YOSHIHIRO
IPC: B66B3/00
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a guidance broadcaster for an elevator car, which reliably notifies occupants in an elevator car that the car has been switched from its normal operation to its controlled operation. SOLUTION: A determination means 7 ascertains that a car has stopped at a predetermined floor and the door has opened, and repeatedly ascertains whether all occupants in the car has got off or not at predetermined intervals. If any occupant is found not having got off the car, a guidance output means 8 outputs its guidance broadcast urging the occupant to get off the car at every determination. The guidance broadcast is repeated until all occupants get off the car.

Title: Solid electrolytic capacitor
Inventor: SEKIYA KAZUO
IPC: H01G9/12
Filed: 1987-10-21
Abstract: PURPOSE:To prevent a sole capacitor from generating heat at the time of causing a malfunction by connecting the anode, cathode leads of a solid electrolytic capacitor element to a terminal strip composed of a printed circuit substrate, and further forming a header at the end of the strip of the leads extended through a fuse provided on the strip to an exterior. CONSTITUTION:A cathode lead 1-b extended from a wire-wound capacitor element 1 is connected by soldering to the land of a terminal strip 2 composed of printed wirings, and a straight type terminal strip cathode lead 4 is extended from the strip 2 in a direction of the exterior of the element through a fuse member 3 soldered with a land. An anode lead 1-a is extended through a hole opened at the strip 2 directly to the exterior of the element. Further, a sheath 5 is formed of a metal case or resin on a whole element including the strip 2. Thus, a solid electrolytic capacitor employing a wire-wound type element can contain a fuse mechanism. Since the fuse is melted at the time of a malfunction and the element is electrically opened, it can prevent the capacitor from generating heat.
