Abstract: PURPOSE:To install a circuit breaker on a connector for blade fuse, and to obtain an operational mechanism that has a clicking sense for freely switching a circuit by providing a recessed part of almost the same curvature as of a moving contact, on a lever comprising insulator, which is provided between a contact part and a moving contact, in such a way that the lever can freely be placed between them. CONSTITUTION:When an overcurrent is flown, a bimetal plate 14 is self-heated, and when it reaches a temperature not lower than a preset level, it is reversed by a snapping operation. A lever 19 is rotated in the right around a supporting hole 19c as a center by the energizing power of a spring 20, and even when the lever is placed on the gap between a contact part 12b and a moving contact 15, and when the bimetal plate 14 is restored thereby, the tongue part of the lever 19 is above the contact part 12b, and a circuit remains cut. When a projection part 19e for ON of the lever 19 is pushed, the circuit is restored. When the lever is formed out of ceramic of the surface roughness of almost not more than Ra 1.25, at the time of restoring the circuit, the moving contact 15 and the lever 19 are slid, and the contact surface is thereby cleaned.

Abstract: PURPOSE:To install a circuit breaker on a connector for blade fuse, and to forcibly switch a circuit by providing a lever which is placed between a moving contact and a contact terminal plate at the time of reverse rotation of a bimetal plate through spring force, and a spring by which the spring force is given to the lever. CONSTITUTION:When an overcurrent is flown in a bimetal plate 14 through contact terminal plates 12, 13, and when the bimetal plate 14 is self-heated until it reaches a preset temperature, it is reversed by a snapping operation. At the same time, moving contacts 15, 16 welded to the bimetal 14 are disconnected from contacts 12a, 13a of contact terminal plates 12, 13. At the time, a lever 19 is moved by the spring force of a spring 20, while an insulating plate 19c is placed between the moving contact 15 and a contact part 12b of the contact terminal plate 12. When the temperature of the bimetal plate 14 is reduced, the bimetal 14 is restored, while, since an insulating plate 19c of the lever 19 is between the moving contact 15 and the contact part 12b of the contact terminal plate 12, the circuit remains opened. To re-close the circuit, an operational part 19b of the lever 19 is pressed, and moved, so as to make the moving contact 15 and the contact part 12b of the contact terminal plate 12 into contact with each other.

Abstract: PROBLEM TO BE SOLVED: To provide a selector valve for a water-supply path having a structure, in which water does not remain in the inside after water is supplied, in relation to the valve for supplying water to a plurality of water-making trays for an automatic icemaker of a refrigerator. SOLUTION: A cylindrical water inlet 1b and discharge ports 1c, 1d are provided on a side face 1a of a main body 1. A channel 2a is formed peripherally in the valve 2, so the valve can be removed slidably rotating on the side face 1a of the body 1. When the channel 2a is positioned between the port 1b and the port 1c (as shown), water coming from the port 1b is discharged through the channel 2a from the port 1d. When the channel 2a is positioned between the port 1b and the port 1d (hot shown), water is discharged from the port 1d. The sectional area D of the water-flow path surrounded by the channel 2a and the side face 1a is constituted to be equal to the sectional area d of the ports 1c, 1d. The velocity of the flowing water hardly changes, and a stable discharge is carried out scarcely having turbulence in the flow, and waterdrops hardly adhere on the flow path.

Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator in which clear ice blocks having reduced cloudiness can be produced through a simple arrangement. SOLUTION: The refrigerator comprises an ice making pan 14 disposed in an ice making chamber 2, a driver 15 having an output shaft 17 for turning the ice making pan 14 by a specified angle to discharge ice blocks therefrom, and a controller 26 for controlling rotation of the drive source of the driver 15, i.e. a stepping motor 16. While sustaining the temperature in the ice making chamber 2 in the range of -7 deg.C through -3 deg.C, the ice making pan 14 is shaken by the driver 15 until water supplied to the ice making pan 14 is changed to ice. When the ice blocks are separated from the ice making pan 14, the ice making pan 14 is twisted for 10 sec or longer at a twisting angle in the range of 10 deg.-30 deg..
