Filed: 1991-02-08
Abstract: PURPOSE:To bond phenolic resin foam, adhesive and arbitrary material together by a method wherein adhesive is applied to some part on the arbitrary material and, further, mixture of phenolic resin, foaming agent, metallic compound and hardener is applied to said part on the arbitrary material. CONSTITUTION:In order to bond phenolic resin foams with arbitrary material 1 through adhesives 2-6, adhesives are applied at least onto some parts of the arbitrary material. Further, mixture of phenolic resin, foaming agent, metallic compound and hardener is applied at least onto said parts of the arbitrary material.

Title: Method for measuring molten pig level in ladle
Inventor: MAKI YUUNOSUKE
IPC: G01B15/00
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To estimate molten pig level substantially accurately by predicting the level based on the variation rate of weight thereof when foaming takes place in the ladle and correcting the predicted level. SOLUTION: A microwave level gauge measures the pig level in the form of a continuous analog quantity which is then sampled at a constant time interval (t sec) and converted into a discrete time series data. It is smoothed through moving average processing in order to remove noise and a current pig level Lm(t) is determined at a time (t) after smoothing. Measurement of the weight of a received pig is also processed and a current weight Wm(t) is determined after the pig is smoothed at the time (t). The predicted value Lp(t+1) of pig level at a time (t+1) following to the time(t) is then determined based on the weight variation rate of Wm(5). It the current level Lm(t+1) of pig level measured by the microwave level gauge deviates significantly therefrom, a decision is made that foaming is generated and the Lp(t+1) is employed as the pig level in place of the Lm(t+1).

Title: Gas laser apparatus
Inventor: YASUI KIMIHARU
IPC: H01S3/097
Filed: 1988-02-01
Abstract: PURPOSE:To obtain a laser beam whose cross-sectional area is large and whose output is large by a method wherein a magnetic field generated in the direction parallel to the laser beam curves an electric discharge to be generated between electrodes in a circular arc shape and forms a discharge space close to a circle. CONSTITUTION:A coil 11 constitutes an electromagnet by an electric current supplied from a direct-current power supply 12, and generates a magnetic field in the direction parallel to the optical axis of a laser beam 6. When a voltage is impressed between electrodes 1, 1a from an alternating-current power supply 2, an electric discharge is curved in an arc shape like, e.g., 10a or 10b as the voltage of the alternating-current power supply 2 is changed to (-) or (+). A gas excited by the electric discharges 10a, 10b curved in different directions at each cycle forms a laser medium; however, because a response to a change in the electric discharge of the laser medium is slow at ten-odd musec in a gas composition of a CO2 laser apparatus, it is possible to obtain the laser medium which is almost steady in terms of the time and nearly circular with respect to a generated beam. By this setup, it is possible to efficiently take out a circular laser beam to the outside of a gas laser apparatus from a nearly circular discharge space B.
