Title: Method for swelling soybean
Inventor: HARA TORU
IPC: A23L11/00
Filed: 1988-12-15
Abstract: PURPOSE:To efficiently swell soybeans in a short time without being affected by a fluctuation in outside air temperature and obtain a product, such as bean curd, having stable quality by dipping the soybean in water and irradiating the soybeans with ultrasonic waves. CONSTITUTION:Soybeans are dipped in water in a dipping tank, irradiated with ultrasonic waves and swelled. Furthermore, the ultrasonic waves can be readily generated by using combined equipment and materials, e.g. ultrasonic generating vibrator and a high-frequency oscillator for driving the vibrator. A frequency within the range of about 20-500kHz is normally preferred as the frequency for the ultrasonic waves. Although the swollen soybeans are used for producing bean curd, etc., impurities, such as epidermises of soybeans, and soil bacteria, such as sporophytes, deteriorating quality of bean curd products can be separated with vibration of the ultrasonic waves during swelling to remarkably reduce the impurities by washing.

Title: Preparation of ruthenium catalyst and device therefor
Inventor: AYABE TSUNEO
IPC: C07C5/02
Filed: 1991-11-29
Abstract: PURPOSE:To obtain highly active and high-quality ruthenium catalyst by adsorbing RuO4 on the surface of a carrier through the content of the carrier with a gas containing RuO4 and ozone at a specified temperature or lower, and further disposing Ru on the surface of the carrier with the heating process of RuO4 in a reduction gas atmosphere. CONSTITUTION:RuO4 is prepared by oxidizing metal ruthenium or ruthenium dioxide in the presence of ozone using an RuO4 synthesis device 1. Then, a carrier 5 of intended shape is stored in a chamber 5 and the RuO4 gas and ozone gas are supplied from the RuO4 synthesis device 1 with a carrier gas. In this case, it is recommended that the interior of the chamber 5 be in a decompressed state and the temperature be lower than 120 deg.C. Consequently, RuO4 is sufficiently adsorbed by the surface of the carrier 4. After that, the carrier 4 in the chamber 5 is heated using a heater 6 with the concurrent feed of a reduction gas into the chamber 5. As a result, the RuO4 on the surface of the carrier is reduced to allow the deposition of ruthenium. Thus a catalyst on which a highly active ruthenium is uniformly carried is obtained.
