Title: Etching apparatus
Inventor: TOKURA TSUNEMASA
IPC: H01L21/3065
Filed: 1990-11-30
Abstract: PURPOSE:To detect the end point of etching of a film formed on the surface of an Si wafer easily by locating a detector which detects infrared rays of the specified wave length at the rear surface side of the Si wafer for detecting the end point of etching of the wafer. CONSTITUTION:A detector 7 which detects infrared rays having the wave length of 1000nm or above at the rear surface side of an Si wafer 2 to detect the end point of etching of the said wafer. Before an aluminum film 13 of the wafer 2 is etched, light in a plasma is reflected on the aluminum film 13 and so the light is not detected by the detector 7. After the etching of the aluminum film 13 is finished, however, the light in a plasma passes the wafer 2 through an opening 14a of a mask 14 to be detected by the detector 7. The infrared detector 7 being connected to the rear surface of the Si wafer 2 through an optical fiber 6, the light in a plasma is cut off by the wafer before etching but it passes through the wafer after etching. Therefore, the end point of etching of the aluminum film 13 of the wafer 2 can be found accurately and easily.

Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To obtain a method in which the non-sealing of a package can be detected surely when the sealing of the package is spoiled even a little by a method wherein a gas having a prescribed viscosity is sealed inside a hollow chamber and a change in the viscosity due to the creep of a gas having another viscosity into the hollow chamber from the outside is detected. SOLUTION: A bottom part 2 and a lid 3 are coupled to each other so as to form a hollow chamber 4. A constituent element 10 which can be vibrated is introduced into the hollow chamber 4. The role of a package 1 is to airtightly seal up the hollow chamber 4 from a surrounding environment. In order to inspect the quality of the sealing performance of the package 1, the constituent element 10 which can be vibrated is used. In order to inspect the package 1, the package 1 is loaded with a second gas at an increased temperature and under an increased pressure. In this case, it is desirable that the second gas has a viscosity which is different as fas as possible from that of a gas sealed inside the hollow chamber 4.

IPC: G03G15/08
Filed: 1990-11-30
Abstract: PURPOSE:To carry out toner replenishment quickly and properly by stopping the carry of toner in the case of detecting the arrival of toner in set-up. CONSTITUTION:When toner is supplied to each hopper 2 of an unused color- image forming device and a power source is turned on, the driving of a driving motor 5 is initiated as a set-up operation.

Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To simplify an entire system without switching a filter characteristic, etc., of radio equipment for a control channel by switching so that control channel data may be sent to radio equipment for a conversation channel when a radio frequency of a control channel receives interference. SOLUTION: In an MCA system, when an interference is detected in a radio frequency of the radio equipment for a control channel, a main CPU 8 controls Do 7 and switches Cch Data to an approach I/F2-3 of S1ch. When an interference is still detected even with this, it further switches to an approach I/F2-4 of S2ch. With this, control channel data are transmitted through radio frequencies of the S1ch and S2ch and approach lines. A radio frequency of the control channels is continuously supervised after switching, and when interference is not detected any more and it is decided that it is recovered, the frequency of an original control channel(Cch) is automatically returned.
