The present invention relates to an explosion-proof seal plate for a sealed cell and a production method thereof and aims at providing an explosion-proof seal plate and production method thereof, wherein problems of a risk of explosion of a cell due to an excessive pressure inside the cell caused by abnormal generation of a gas through a chemical reaction accompanying over charge or erroneous use of the cell or damaging of electronic equipment using the cell as the power source are solved, ignition and other accidents can be prevented with a high accuracy by reliably cutting off an electric current when the cell internal pressure increases, and the increase in the resistance due to permeation of an electrolyte can be limited. In order to accomplish this aim, the present invention provides a thin portion 7a having a breaking strength of 18-24 kg/cm2 in the central portion of an upper metallic foil 7 made of aluminum and a thin portion 8a having a breaking strength of 10-13 kg/cm2 in the central portion of a lower metallic foil 8 made of aluminum, wherein the diameter A of the thin portion 7a of the upper metallic foil and the diameter B of the thin portion 8a of the lower metallic foil 8 satisfy the relation AB. The two metallic foils are welded at the central portions with an insulating gasket interposed, and encased in a metallic case 4 made of aluminum having 4 vent holes, on top of which a temperature dependent resistor 5 and a metallic cap 6 having 4 vent holes are then placed. A seal plate is obtained by sealing the periphery of the metallic case 4, with which it is possible to prevent accidents such as ignition and explosion of a cell by reliably allowing internal gas to exhaust in the event of generation of a large volume of gas under an abnormal condition of a sealed cell.

摘要:
When information held in an information holding section is distributed from an information distribution section to another information intervention system, a distribution sensing section senses the information distribution and records a distribution history thereof in a distribution history holding section. When an instruction for tracing information is given,a history collection section reads out the distribution history related to the information to be traced from the distribution history holding section, detects the distribution destination of the information, and instructs the information intervention system of the distribution destination to trace the information. History information is collected from the instructed information intervention system and is stored in a collected history holding section. The collected history information is analyzed by a tracing analysis section. For example, distribution routes, etc., are displayed on a tracing result display section.
摘要:
A dummy wafer for use in a process for thin film formation on a wafer, which is made of a silicon carbide obtained by reacting a glassy carbon with silicon or with a silicon-containing gas, or comprises (1) a silicon carbide obtained by reacting a glassy carbon with silicon or with a silicon-containing gas and (2) a silicon carbide layer formed thereon by CVD. This dummy wafer alleviates the problems of the prior art; shows no warpage and contains no metal to become a contamination source for a semiconductor; has corrosion resistance to hydrofluoric acid, hydrochloric acid, etc., heat resistance and resistance to repeated heat cycles; and is inexpensive.
摘要:
When an information distribution section receives information sent from another information intervention apparatus, a distribution sensing section senses it and records a distribution history in a distribution history holding section. Each information intervention apparatus transmits distribution histories to a tracing center via a history sending section. In the tracing center, a distribution history collection section collects the distribution histories transmitted from the information intervention apparatuses, and stores those into a distribution history holding section. A tracing analysis section 23 analyzes an information distribution route etc. based on the distribution histories stored in the distribution history holding section 22. An analysis result display section 24 displays an analysis result.

摘要:
A window glass holder comprises a pair of axially spaced plate members having coaxial through-bores defined therein. A first one of the plate members has a protrusion which comprises a shoulder portion and an inclined ramp portion. The second one of the plate members has a metal nut member embedded therein. When a window glass is to be inserted into the window glass holder, the bottom edge portion of the window glass is inserted into the space defined between the pair of plate members such that the bottom edge portion of the window glass encounters the inclined ramp portion of the first plate member causing the first plate member to move away from the second plate member. When a through-bore defined within the window glass is coaxial with the through-bore and protrusion of the first plate member, the protrusion will be snap-fittingly engaged within the through-bore of the window glass whereby the window glass will be fixedly retained within the window glass holder. A threaded bolt fastener can be inserted through through-bores of the rail member, the plate members of the window glass holder, and the window glass so as to threadedly engage the nut member of the second plate member whereby the window glass holder and the window glass are fixedly secured to the rail member.
摘要:
An information processing method and an information processing system for recording information concerning a distribution route of one information, thereby enabling the information distribution route to be traced later. Information held in an information holding section 11 has distribution history information held in an information label section. When information is sent from one information intervention system to another information intervention system, a distribution history write section 15 reads a system identifier from a system label section 14 and adds a sending history to the distribution history information of the information. When information is received from another information intervention system, likewise a reception history is added to the distribution history information of the information. A tracing result display section 16 fetches the distribution history information of specified information, carries out an analysis on it, and displays the analysis result in a predetermined display format. Seeing the display, the use can easily know the information distribution route, etc., later.
