Abstract: PROBLEM TO BE SOLVED: To make vibration-proofing and sound-proofing process unnecessary, and comparatively simply remove high frequency noise, by setting the minimum detection sensitivity of a rotation angular velocity sensor which detects the rotation angular velocity of the earth, as a threshold-value, and eliminating noise components in a high frequency region, form detected angular velocity. SOLUTION: This azimuth detection equipment consists of a rotation angular velocity sensor 1 which detects the rotation angular velocity of the earth, and an operating part 4 constituted of an ROM 2 which stores the minimum detection sensitivity and a CPU 3 calculating the azimuth of a sensor main axis from the detected angular velocity. The CPU 3 samples several points of the angular velocity from the rotation angular velocity sensor 1, obtains an average angular velocity from the sampling angular velocity in order to remove one shot noise, and extracts only the data which exceed the region of the minimum detection sensitivity (threshold value), from the average angular velocity.  In order to remove discrete noise which is superposed on the rotation angular velocity and outputted, the left angular velocity is processed with an LPF, and the azimuth is calculated from the angular velocity after filtering. Thereby, azimuth detection of high precision is enabled.

IPC: F25B9/02
Filed: 1990-07-26
Abstract: PURPOSE:To manufacture pressurized HeII within a short period of time by a method wherein an inside part of a container is reduced in its pressure, liquid helium is cooled to change it into saturated ultra-flowing helium, helium is thermally insulated at an intermediate part of liquid layer, a cold state keeping region is formed below it, the inside part of the container is pressurized and then pressurized region flowing helium is produced within the cold state keeping region. CONSTITUTION:A safety valve 16 is opened, HeI is inputted into a container, and a liquid surface level 28 of HeI is set higher than that of a separator 12. A vacuum pump is operated to discharge evaporated He in a container 10, an inside part of the container 10 is reduced in its pressure to generate saturated HeII and then the safety valve 16 is closed. Although an upper part and a lower part of the saturated HeII are thermally insulated with a separator 12 being applied therebetween, a slight clearance is present between the safety valve 16 and the separator 12, so that pressure above the separator 12 and pressure below the separator 12 are kept uniformly to each other. A compressor is operated to supply helium gas into the container 10 and an inside part of the container 10 is pressurized substantially up to atmospheric pressure. Saturated HeII present in the pressurized HeII tank 14 acting as a cold state keeping region is pressurized substantially up to atmospheric pressure while being kept at a low temperature state and then the pressurized HeII is produced.

Title: Dry etching of resist film
Inventor: TANNO MASUO
IPC: H01L21/3065
Filed: 1985-09-10
Abstract: PURPOSE:To enable a resist film to be dry-etched by means of using mixed gas of oxygen and nitrogen as reaction gas. CONSTITUTION:When a resist film is etched using an SiO2 film formed by coating-backing process as an etching mask, a mixed gas of O2 and N2 or another mixed gas of O2, N2 and fluoride is used as reaction gas. Due to the utilization of mixed gas of O2 and N2 as reaction gas, the plasma component of N2 restrains the plasma reaction to plasma component of SiO2 film and O2 so that the etching speed of SiO2 film may be decelerated while keeping the etching speed of resist film as it is. Besides, due to the utilization of mixed gas of N2, O2 and fluoride as reaction gas, the etching speed of resist film can be further accelerated while keeping the etching resistance of SiO2 film as it is.
