Patent JP-S60165042-A (JP)
Title: Manufacture of flat type battery
Inventor: HORIIE HIROSHI
IPC: H01M50/186
Filed: 1984-02-07
Abstract: PURPOSE:To always obtain good continuity between an electrode and a sealing plate by containing a battery under the heating atmosphere heated at a temperature at which solder can be melted under atmospheric pressure. CONSTITUTION:A spacer 3 in which metalizing processing is applied to a joining surface beforehand is loaded on a sealing plate 1 that is presoldered to a peripheral section and a power generating element 4 is arranged placing the positive electrode 5 side upside down. A sealing plate 2 that is presoldered to the peripheral section is loaded on it and the entire is contained in an infrared imagefurnace. After the entire is heated up to 150 deg.C while it is being pressurized and then heat-insulated for one minute at 150 deg.C, the entire is cooled up to the room temperature for 30min in the furnace. Since the gas confined in a battery is reduced in volume after joining due to the temperature fall, the central part of the sealing plate 2 is recessed and makes contact to a negative electrode 7. As a result, the continuity between the negative electrode 7 and the sealing plate 2 is kept good at all times. For example, solder is made of tin-zinc-bismuth alloys and the melting point reaches approximately 100 deg.C.

Abstract: PURPOSE:To establish dry vacuum formation by feeding a sample from a frist sample chamber to a second sample chamber, achieving advance or retreat of a feed mechanism in a condition releasing it from engagement with a sample holder and introducing the sample from the second sample chamber to the first sample chamber. CONSTITUTION:A sample holder 4 provided in a sample chamber 1 is transferred to a sample exchangeable position. The sample chamber 1 is communicated by opening a gate valve 3 with the a sample replacing chamber 2 and a chuck/unchuck mechanism 13 is introduced, by switching the lever 13 (9) of the chuck mechanism 13, to the sample chamber 1. In this case, a roller 13 (8) at the top end of the chuck/unchuck lever 13 (2) meets with the slot of the sample holder 4 within the sample chamber 1, subsequently the sample holder 4 is drawn out to the sample replacing chamber 2 by reversely rotating a feed screw. The gate valve 3 is closed, the sample chamber 1 is separated in vacuum from the sample replacing chamber 2, subsequently the atmosphere introduced into the sample replacing chamber 2 is made equivalent to the atmospheric pressure, a lid 16 is opened by revolving it around a fulcrum 15 and a silicon wafer 5 is replaced. Thereby, dust generated in replacing the sample can be prevented and dry vacuum formation can be established.
