Abstract: PURPOSE:To improve washing effect and permit water supply suitable for making washing automatic, by providing a water discharge chamber and an air bubble generating pipe in a tank body, and arranging detectors at given portions of washing chambers, the water discharge chamber and a pipetting tray. CONSTITUTION:A pipetting device washing chamber 5 and a coating tool washing chamber 6 are supplied with water from a feed water pipe 7. When the water level rises so that detectors a and b conduct to each other, a pipetting device nozzle 1 and a coating tool pen point 2 are moved downward into the respective washing chambers. Then, air bubbles are generated from the peipetting device nozzle 1 itself and an air bubble generating pipe 8 to perform washing. In said washing, the water overflowing the washing chambers 5 and 6 flows in a water discharge chamber 4 through the partition part and an overflow hole 17. When detectors c and d thereby conduct to each other, a solenoid valve 23 is opened, so that the water is discharged into a purifying tank 11. After the washing process, a sample is pipetted to a pipetting tray 12 by means of the pipetting device nozzle 1 and applied to a carrier by means of the coating tool pen point 2. Thereby, an effective washing can be performed with a smaller amount of water at all times.

IPC: H01L21/3065
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce the dimensional conversion difference in the patterning by setting the angle between the surface of a material layer to be etched and side wall of a resist mask to a value exceeding the retrogressing angle of a resist mask by etching and less than the deposition angle of a fluorocarbon type polymer on the side wall of the mask.

This provides a correlation of the angle between the material layer surface and inside wall of the resist mask with the amt. of the side wall deposited polymer and dimensional conversion difference. If the mask 6 is designed for the angle in this range, the dimensional conversion difference can be reduced and stably controlled.

Abstract: PURPOSE:To attain the satisfactory recording and erasion even with small intensity of a magnetic field by using a member which transmits a laser luminous flux to form a magnetic gap part and supplying the laser light to said gap part in a recording or erasing mode to heat a magnetic film. CONSTITUTION:A magnetic gap part is formed at the tip of a core 1 of a magnetic head with a member 3 that transmits a laser luminous flux. Then the laser luminous flux given form a laser light source 4 is supplied to the magnetic gap part through an optical path 5 in a recording or erasing mode of the information signal. Thus the magnetic film of a magnetic recording medium is heated up to a temperature approximate to a Curie point. This ensures the satisfactory recording of the information signal to the magnetic film of the recording medium despite small intensity of a magnetic field produced at the magnetic gap part. At the same time, the signals recorded on the magnetic film can be erased satisfactorily.

Abstract: PURPOSE: To improve the combustion efficiency of an ultrasonic vaporization combustion system by applying ultrasonic vibration to combustible liquid fuel and auxiliary fuel such as water, alcohol or the like to thereby alter them to fine foggy particles and intaking them by an air pump or the like to then pressurize them and to burn them.   
     CONSTITUTION: When an ultrasonic vibrator 6 mounted on the bottom of a vaporization tank 3 is driven to radiate ultrasonic beam toward liquid surface and to focus the beam in the vicinity of the liquid surface, fuel is instantaneously atomized to become vaporized gas 12. A solenoid valve 2 is controlled to open or close by a liquid surface level detector 4 at this time to thereby retain the liquid surface in the tank 3 at constant level. Then, an air pump 7 is driven to intake and pressurize the gas 12 and to open a solenoid valve 10 via a check valve 9 to thereby inject the gas 12 from an injection port 11 and to then ignite and burn it. When fuel containing combustible liquid and auxiliary fuel such as water, alcohol or the like is vaporized thus and is then burnt, it can improve the combustion efficiency of this ultrasonic vaporization combustion system.
