Patent JP-H04171928-A (JP)
Title: Etching method
Inventor: OKUNI MITSUHIRO
IPC: H01L21/3065
Filed: 1990-11-06
Abstract: PURPOSE:To prevent an object to be worked from taking in fluorine during etching, by AL alumite-treating the inner wall of an etching reaction chamber, and etching the object to be worked arranged in the etching reaction chamber, so as to be brought into contact with plasma of gas which contains bromine or hydrogen bromide. CONSTITUTION:The inner wall of a reaction chamber is subjected to AL alumite treatment under the following conditions; pressure is 80mTorr, RF power is 250W, electrode temperature is 35 deg.C, and the gap between an upper electrode 13 and a lower electrode 14 is 85mm. By using bromine or hydrogen bromide gas, the Si-Si bond can be cut without cutting the Si-O bond in the reaction process of etching. When the inner wall of the reaction chamber is subjected to aluminum alumite treatment and constituted of material which does not contain fluorine, e.g. Teflon-coated material, adverse influence of the strong bond of Si-F is not exerted, so that high selection ratio (polycrystalline silicon to SiO2) can be obtained.

Title: Screw cap to ensure not being opened
Inventor: ETO MAKOTO
IPC: B65D41/34
Filed: 1993-10-27
Abstract: PURPOSE:To ensure that a cap has never been opened though it is easy to open by a method wherein a shear cutting torque at a cutting line at a connection part of a band part and a cap is set at a middle value between a torque at an interface on a container side of a fixing part and a shear tearing torque at an interface on the band part side. CONSTITUTION:A fixing part 4 is arranged between a band part 2 and a container body 3 to connect fixedly the band part 2 and the container body 3 together. The band part 2 is connected to a lower end of a screw cap 1 at a connection point 6 and a cutting line 7 is provided at the connection part, so that one end of a weak part 5 is raised and pulled up to tear the band part 2 from the container body 3 and further cut it at the connection part of the cap end. At this time, a shear tearing torque at an interface between the band part 2 and the container body 3 is set to be not enough for opening easily by hand, and the cap cannot be opened unless the band part 2 is cut off. Therefore, once the cap is opened, the fact that the cap has been opened once can be known apparently, and thereby it can also be ensured without fail that the cap has never been opened yet.

Title: Optical disk reader
Inventor: HACHI YASUO
IPC: G11B7/09
Filed: 1988-11-30
Abstract: PURPOSE:To stably read a control track by performing fine alteration of a tracking position by using the error of read data as a trigger and performing re-read. CONSTITUTION:When an optical pickup is shifted with respect to the control track, a shift direction calculation means obtains to which direction in the radius of the optical disk the optical pickup shifts. Namely, a detection modulation signal (a) which a two-dividing sensor 38 has read can be obtained from an adder 40, and is supplied to a top level detector 44 and a bottom level detector 46. When a check means outputs the error, a control signal output means adds a control signal corresponding to the direction of shifting to a transfer means and the optical pickup is finely adjusted. This is repeated until the error is eliminated. Thus, the information reading of the optical track can securely be performed.

Title: Wet etching
Inventor: UCHIYAMA MAKOTO
IPC: H01L21/306
Filed: 1987-12-02
Abstract: PURPOSE:To uniformly, accurately and selectively etch a conductive film by holding the nonetching side of a conductive substrate in a noncontact state from etchant, and advancing a selective etching. CONSTITUTION:The rear face of an Si substrate 4 is held in a noncontact state from etchant 20 during wet etching. Accordingly, even if a conductive film is electrically connected to the substrate 4, the rear face of the substrate 4 is prevented from becoming a cathode electrode, no etching occurs due to dissimilar metal contact with an anode of the conductive film and a cathode of the rear face of the substrate. Thus, with a progress of the selective etching, the conductive film is isolated to a region to become wirings or the like and a wiring pattern electrically connected to the substrate 4 and an insulated wiring pattern are formed. Then, both are similarly etched on the basis of local battery forming action, the uniform etching makes progress, a phenomenon in which special wiring or pad is abnormally thinned is prevented, thereby performing an accurate etching.

Filed: 1994-11-11
Abstract: PURPOSE: To obtain a spectrum analyzer whose high measuring accuracy is enhanced with reference to only a specific frequency band by a method wherein a high-accuracy frequency-characteristic correction means is installed with reference to the specific frequency band as an object. CONSTITUTION: On the basis of a central-frequency setting operation from a setting panel 96 and on the basis of a frequency-span-setting input condition, it is judged whether a specific frequency band to which a precision frequency correction is to be executed is in a measuring state or not. When the specific frequency band is in the measuring state, the correction and arithmetic- processing operation of a frequency characteristic is performed with good accuracy and fine by means of precision-correction offset data 22a in a precision- frequency characteristic correction memory 22 so as to be output. On the other hand, when the specific frequency band is not in the measuring state, a precision-frequency correction part 20 which outputs the frequency characteristic as it is without performing the correction and arithmetic-processing operation is installed.
