    摘要: An apparatus for analyzing oxygen, nitrogen and hydrogen which are contained in metals. The apparatus includes a graphite crucible which has a sample therein and which is heated to generate a gaseous mixture of CO, N.sub.2 and H.sub.2. An oxidizer is used to oxidize the CO and H.sub.2 into CO.sub.2 and H.sub.2 O, respectively. The apparatus further includes a thermal conductivity detecting means for detecting CO.sub.2, N.sub.2 and H.sub.2 O, coming from a first gas-chromatographic column which is used for separating H.sub.2 O from the CO.sub.2 and N.sub.2. A second gas-chromatographic column is used for separating CO.sub.2 from N.sub.2. A passage change valve is used for back-flushing the first column. Helium is preferably used as the carrier gas. The apparatus is simple and operates quickly because the three components, O, N and H, can be measured by using a single carrier gas He and a single sample and thus, only a single measurement operation is required.

    摘要: A liquid vaporizer-feeder has a unitary housing structure for both a control valve for controlling the amount of a liquid passing therethrough and a vaporization valve for causing the liquid from the control valve to be vaporized and transported out by a carrier gas. The housing structure has a throughhole through which the two valves are connected. The throughhole is short and narrow, and has a portion made even narrower such that the pressure in the liquid passing therethrough is increased, preventing bubbles from forming in the throughhole. As a result, vaporized liquid can be supplied at a steadier rate, for example, to a reaction chamber.

    摘要: A mass flow controller having a bypass portion provided in a body through which a large amount of gas is passed and a sensor portion, laid between a primary chamber which is an inlet of the bypass portion and a secondary chamber which is an outlet of the bypass portion, through which gas flows at a small flow rate proportional to the flow rate of the gas passed through the bypass portion and capable of measuring the total flow rate of gas by measuring the flow rate in the sensor portion. The body is partitioned by a bulkhead into a primary chamber and a secondary chamber. The primary chamber is provided with an inlet for gas inflow and the secondary chamber is provided with an outlet for gas outflow. The bulkhead is provided with a plurality of through holes for connecting the primary chamber to the secondary chamber, and bypass elements selected depending on the flow rate in the bypass portion are fitted in the through holes in the bulkhead. Expansion plugs are fitted in the through holes in which no bypass elements are fitted not to cause gas to flow.

    摘要: Since the IC card does not have a power source in an ordinary case, the power is supplied thereto from the IC card reader/writer via the contact electrode. According to the present invention, a current detect unit is disposed between the power source of the IC card reader/writer and the contact electrode for the power supply to detect the presence/absence of the current supply. A data signal can be delivered from the IC card reader/writer to the IC card only when the current supply is detected by the current detect unit so as to prevent the latch-up phenomenon due to an insufficient contact between the electrodes of the IC card particularly including a complementary MOS and the electrodes of the IC card reader/writer, thereby preventing the destruction of the IC card.

    摘要: Fixed amounts of a liquid source for a chemical vapor deposition process is supplied continuously from a source tank and through a liquid mass flow controller to a three-way valve. Inside the three-way valve, the liquid source is evaporated to generate a source gas by contacting a high-temperature carrier gas which flows therethrough and becomes mixed with the source gas. The gas mixture thus generated is supplied into a process chamber for a chemical vapor deposition process. The carrier gas may be heated by a gas heater before entering the three-way valve. Alternatively, the three-way valve may be enclosed inside a thermostatic container, the carrier gas being heated inside the container.
