IPC: B23K13/06
Filed: 1988-12-27
Abstract: PURPOSE:To always perform gas shielded welding of a seam welded tube under optimum conditions by sampling atmosphere gas of a weld zone by a suction pipe in a shielding gas injection nozzle on the upper part of a V joining point and measuring continuously oxygen concentration of the sampled gas. CONSTITUTION:While a steel strip being formed continuously, both edges of an open pipe 1 are heated to manufacture the seam welded tube. The shielding gas injection nozzle 3 is arranged on the upper part of the V joining point 2 which is shielded by shielding gas to inject from the nozzle 3 and welding is performed thereon. At that time, the suction pipe 4 for gas sampling is inserted into the shielding gas injection nozzle 3. The atmosphere gas of the weld zone is then sampled by the suction pipe 4 and the oxygen concentration of the gas is measured continuously by an oxygen concentration meter 5. The tip of the suction pipe 4 for sampling is located at the upstream side 15-30mm from the V joining point and at 5-8mm from the edge upper surface.

Abstract: PURPOSE:To perform stable tracking servo. CONSTITUTION:The reflected light from an optical disk is received by a photodetector 1, and the phase difference between diagonal sums of light receiving faces 1a to 1d of the photodetector is denoted as a time difference error signal, and the difference signal between two areas divided by a boundary line along the track of the optical disk is denoted as a push-pull error, and these signals are mixed. At the time of opening the tracking servo, the amplitude value of the push-pull error signal is detected by a level detector 13, and the extent of attenuation of an attenuator 11 or 26 is controlled in accordance with this detection output to vary the mixture ratio of respective signals. Since the mixture ratio of the push-pull error signal and the time difference error signal is properly controlled in accordance with the level of the push-pull error signal at the time of opening the tracking servo, the variance of the gain of the push- pull error signal dependent upon the pit depth is controlled to perform the stable tracking servo.

Title: Eye drop, installation auxiliary and eye drop holding vessel
Inventor: SHIMODA SETSUO
IPC: A61J1/05
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain a new eye drop enabling the thorough therapy of hypolacrimation, by activating the lacrimal source/transport system of a portion from the lacrimal gland tissue or lacrimal gland to the lacrimal duct. SOLUTION: The plot lines F-J in the figure indicate that, as oxidation- reduction potential decreases, and as initial head difference increases, the rate of change with time of osmotic pressure (i.e., rate of osmosis) in the initial stage of osmosis (through about 5h) increases sharply; in particular, the lower the oxidation-reduction potential, the shorter the time necessary for rising up to the maximum rate of osmosis. Therefore, to obtain an eye drop with rapid- acting infiltrativity, it is effective to use water with lower oxidation-reduction potential; water <=200mV in oxidation-reduction potential has marked immediate effect on the infiltrativity on the lacrimal transport system. When this eye drop is used, restoration of the lacrimal secretion of patients affected with hypolacrimation can be recognized significantly.
