IPC: G01F23/28
Filed: 1994-05-27
Abstract: PURPOSE:To measure a liquid level independent of temperature change of liquid by calculating ultrasonic wave propagation speed on the basis of a signal from an ultrasonic wave measurer connected to an ultrasonic wave transciever mounted on the bottom wall face of a liquid housing part, finding temperature of the bottom wall, and calculating a liquid level from the temperature and a measured signal. CONSTITUTION:An ultrasonic wave transceiver 3 is mounted on the bottom wall face of piping 1, and an ultrasonic wave measurer 5 is connected thereto. An ultrasonic wave is propagated and transmitted in the bottom wall of the piping 1 and in liquid on the basis of a signal from the transceiver 3, the measurer 5 measured a time t1 up to receiving of an echo wave reflected on a liquid surface 2, and time t2 up to receiving of the cho wave in the bottom wall from transmission of the ultrasonic wave. A liquid level is found from a time interval of the echo wave and an ultrasonic wave propagation speed in the liquid found by the measurer 5, at that time, the propagation speed is calculated by a temperature operation device 8 on the basis of the time t2 and bottom wall thickness, and the bottom wall temperature, namely, temperature of the liquid is found. In response to the temperature signal a correction of the propagation speed in accordance with the time t1 is performed by an operation processor 6 and the liquid level is obtained.

Title: Removing process of resist film
Inventor: YAMAO TATSUHIKO
IPC: B05D3/06
Filed: 1984-07-03
Abstract: PURPOSE:To remove a resist after exposure easily at room temperature without utilizing a plasma ashing device by a method wherein, after irradiating a negative resist pattern on a substrate by rays with specific wavelength, the substrate is immersed in an acid or organic solvent. CONSTITUTION:A masking substrate 1 is coated with a chrome film 2 and negative resist 3 while the negative resist 3 is exposed to electric beams and developed to form a resist pattern 5. Then a chrome pattern 6 is formed utilizing the pattern 5 as a mask. Next the resist pattern 5 is removed by means of irradiating it with far ultraviolet rays 7 with central wavelength not exceeding 300nm for 10min and then immersing it in concentrated sulfuric acid at room temperature for 3min. The irradiation time with far ultraviolet rays required for removing resist may be shortened by means of raising the substrate temperature in case of irradiating the substrate with far ultraviolet rays. In other words, the irradiation time with far ultraviolet rays takes 10min when the substrate temperature is at room temperature but if it is raised up to 200 deg.C, 1min will suffice for the irradiation.

The heavy ions are elements 10 or over in number of mass, and at the time of ion implantation, the intensity of implantation is adjusted so that the peak of the ion density may come to the roughly central part of the crystal layer. Then, the climb motion is accelerated by heating it at a temperature higher than the growth temperature of the crystal, and the dislocation absorbs extinguish the voids. The temperature of heating will do so long as it is enough for dislocation to absorb and extinguish the voids and that within the range of time which does not affect the properties of a semiconductor element.

For example, a lead wire 3 is fixed to one end of an inner electrode 1. The film agent is applied on the other end of the inner electrode 1. Thus, a sensitive film 3 is formed. A part of the inner electrode 1 on which the film agent is not applied is coated with a body 4. A cap 5 covers one end. When the coated electrode is submerged into aqueous solution containing anions or hydroxide ions, the ligan of the central metal of the cobalt-5,10,15,20-tetra(2-nitrophenyl)-porphyrin cloride complex is changed. Thus, the iodine ions or the hydroxide ions can be selectively measured in a short time.
