Title: Switch
Inventor: KII MASAMI
IPC: H01H33/18
Filed: 1990-07-31
Abstract: PURPOSE:To uniformly cool the center are of an arc by means of a gas blown and shorten the time during which the arc exists and enhance the performance of a switch by guiding the center of the arc to the center position of an arc space, and then binding the same. CONSTITUTION:When a piston rod 18 starts to fall down, a fixed contact 11 and a movable contact 15 are separated from each other and an arc is generated between the contacts 11, 15. The rod 18 further falls down and the interval between the movable contact 15 which operates in conjunction with the rod 18 and the fixed contact 11 is increased and also the arc is extended and finally brought to its initial to break a circuit. Also a buffer device 23 is actuated in conjunction with the rod 18 so that gas in a cylinder 21 reaches pressure appropiate for breaking the circuit. During the process in which an arc current decreases and comes close to a zero value, an opening 12 is opened and high pressure gas in the cylinder 21 is allowed to flow into an arc space through a passage 24 and discharged from the opening 12. Then the arc has already been turned to the right and also the high pressure gas is allowed to flow in through a deflecting vane 20 while being revolved to the left at high speed, so that the arc is strongly diffused in the perpendicular direction. Next the arc current becomes zero and the arc is extinguished.

Abstract: PURPOSE:To obtain an individual package free from scattering of contents at the time of unpacking by making a constitution wherein a deformable part of a container bottom takes a protrusion shape with a rib part as a border when a lid material part is pressed. CONSTITUTION:Into a container 6 obtained by vacuum-molding a polypropylene sheet with a part 3 deformable into either a recess or a protrusion into a protrusion via a rib part 2 having a hinge effect along an inner periphery of a bottom 1, concentrated coffee of 80 deg.C is put with the deformable part 3 in a protrusion, and after the container is heat-sealed with a lid material 5 of an aluminum foil to be completely sealed, the deformable part 3 is deformed into a recess to have an individual package completed. When the lid material 5 is pressed by a finger at the time of use, the deformable part 3 is in a protrusion to reduce a pressure inside the container 6 so that a liquid level of the concentrated coffee 4 further lowers. When the content 4 is to be put in at a room temperature, the deformable part 3 is deformed into a recess and the contents is put, and then the lid material is heat-sealed, while by pressing the lid material 5 with a finger at the time of use, the deformable part 3 is deformed in a protrusion to reduce a pressure inside the container. Therefore the content may not scatter when the lid material is removed from the container.

Title: Reference temperature generating device
Inventor: TAKADA MASASUKE
IPC: G01K15/00
Filed: 1994-08-30
Abstract: PURPOSE: To provide a reference temperature generating device whose structure is extremely simple and by which manufacturing cost is remarkably reduced by arranging a wire rod composed of a prescribed oxide high temperature superconducting ceramic material and an electric power supply circuit to impress prescribed voltage on both ends of the wire. CONSTITUTION: When prescribed voltage is impressed on a wire 1 composed of oxide high temperature superconducting ceramic from electric power supply E, a local Joule red heat point 2 appears on the wire 1. Due to fine structural nonuniformity of the ceramics, when a single point 2 (a maximum resistance value part) of a sample wire is made red hot to 400 deg.C or more by generation of Joule heat by impression of voltage not less than a prescribed value, resistance of this part increases by the occurrence of an oxygen deficiency. Voltage to be impressed on this red hot point 2 increases by an increase in the resistance.  Therefore, though the red hot point 2 rises in the temperature according to an increase in a heating value while moving in the electric current direction, since the resistance of the red heat point reduces with 900 deg.C as a boundary, a temperature of the red hot point 2 is stabilized at 900 deg.C. Yttrium based, bismuth based and thallium based ceramics are used as the wire.
