Title: Resistance spot welding method of laminated metallic plate having electrical insulating film
Inventor: KABASAWA MAKOTO
IPC: B23K11/16
Filed: 1983-07-18
Abstract: PURPOSE:To prevent the expulsion and surface flash in the intermediate layer of laminated metallic plates by providing a cooling period when current conduction is stopped upon ending of preheating time and executing the main current conduction in succession thereto. CONSTITUTION:Laminated metallic plates having an electrical insulating layer are preheated by current conduction and after the cooling time by >=0.02sec non- current conduction upon ending of the preheating time, the laminated metallic plates are subjected to main current conduction and are joined by welding. A relay R1 stops the welding current upon ending of the preheating time and a relay R2 resumes the conduction of the welding current upon ending of the cooling time. A relay R3 stops the welding current upon ending of the main weld time. The respective time are determined by a voltage comparator circuit 11, a timer T2 and a timer T3.

Abstract: PURPOSE:To inform it to an external device that a counter charge prevention diode of a primary battery is destroyed or short-circuited by connecting a series connection comprising a counter charge prevention diode, a current limit resistor and a backup primary battery in parallel with a semiconductor memory element and providing a light emitting element and a resistor in parallel with the current limit resistor. CONSTITUTION:When counter charge prevention diode 4 is destroyed or short- circuited, a power supply from a terminal equipment is fed to a primary battery 2 via current limit resistors 3, 6 and a light emitting diode 7 to counter-charge the battery 2. That is, the primary battery 2 is counter-charged by a current being the sum of a current Ia flowing to the current limit resistor 3 and a current Ib flowing to the current limit resistor 6 and the light emitting diode 7. Since the current Ib is enough to light up the light emitting diode 7, the light emitting diode 7 is lighted. The current flowing thereat is limited by the resistor 6. Thus, the user recognizes it that the counter charge prevention diode 4 is destroyed resulting in short-circuit.

Title: Elevator device
Inventor: OKADA KOJI
IPC: B66B11/04
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To minimize noise inside a car during operation of the car and give silence to the inside of the car easily with a simple structure in an elevator whose car is disposed in proximity to a hoist. SOLUTION: A main wire 10 is wound around a hoist 3 installed inside a hoistway 1 to be tensed inside the hoistway 1. A noise insulation body 12 is fitted, which is of box type, covers the hoist 3 and is protrudingly-formed with a noise absorbing duct 13 through which the main wire 10 passes. The noise generated by the operation of the hoist 3 is absorbed in the noise insulation body 12 and the noise absorbing duct 13. Therefore, the quantity of the noise which is generated at the hoist 3 and transmitted to a car 11 is small even if the car 11 is disposed in proximity to the hoist 10. It is thus possible to give silentness easily to the inside of the car 11 as well as a neighboring place at which an elevator hall is installed.
