摘要:
In a soldering method for soldering an electronic component including a palladium or palladium alloy layer formed on a surface of the electronic component and also including a soldering lead terminal onto a printed wiring board including a soldering land and plated through hole, a solder layer containing tin and zinc as main components is formed on the surfaces of the land through hole by a HAL treatment. The lead terminal is inserted and mounted in the through hole. The printed wiring board is brought into contact with jet flows of a solder containing tin and zinc as the main components to thereby supply a solder to the land and through hole.

摘要:
A packet analysis system captures packets propagating through a network, and analyzes the captured packets. The packet analysis has a plurality of terminal node type sensors and a server. Each of the terminal node type sensors captures packets propagating through the network, and classifies the captured packets. A server acquires classification information from at least one of the terminal node type sensors through the network, and generates a whole report of the packet analysis system based the acquired classification information.

A refrigerator unit is configured for a container in which it is possible to know the quantity of air that is ventilated. The refrigerator unit is equipped with a ventilation mechanism, an opening degree detecting mechanism, and a recording unit. The ventilation mechanism ventilates the air inside the container. The opening degree detecting mechanism acquires ventilation data related to the quantity of air ventilated by the ventilation mechanism. The recording unit records the ventilation data acquired by the opening degree detecting mechanism.

A carcass (14) includes two carcass plies (16) and (17). A carcass cord is provided at an angle of 65 to 88 degrees with respect to the circumferential direction of a tire (10). The carcass ply (16) is wound upon a bead (13) from an inside toward an outside in a radial direction. The carcass ply (16) overlaps symmetrically in a crown portion (18). The carcass plies (16) and (17) are fastened and reinforced in the radial direction by means of a band (15). An overlapping dimension (Wo) of the carcass ply (16) is set to be 30% to 90% of a tread width (W). The carcass ply (17) is extended to have a height (h) along a sidewall (12). The height (h) is set to be 20% of a height (H) of the sidewall (12) or more.
摘要:
A heat treatment apparatus for applying a predetermined heat treatment to a substrate includes: for example, a dielectric low oxygen controlled cure unit (DLC unit) for forming an interlayer insulating film on a semiconductor wafer W; a hot plate for supporting the wafer W a predetermined distance apart from the surface thereof; a chamber for housing the wafer W; a gas collecting port formed in that portion of the hot plate which corresponds to the lower side of the wafer W when the wafer W is disposed on the hot plate; and an oxygen sensor for measuring the oxygen concentration in the gas collected from the gas collecting port. Since the oxygen concentration can be measured during the heat treatment to the wafer W, the characteristics of the interlayer insulating film formed can be maintained constant.
