Title: Method for preventing dried noodle from cracking
Inventor: SUGISAWA AKIRA
IPC: A23L7/109
Filed: 1982-05-27
Abstract: PURPOSE:After drying, raw noodles or steamed noodles are subjected to tempering treatment under an appropriately adjusted humidity at a certain high temperature so that the water uniformly distributes in the noodle lines rapidly, thus preventing noodle lines from cracking. CONSTITUTION:Raw noodles or steamed noodles are subjected to high-temperature drying treatment to give dried noodles of such a lowered water content as they can be stored for a long period of time. Immediately after drying, the resultant noodles are subjected to tempering treatment at 50-100 deg.C. Since the present process is effected at high temperature, noodles are kept flexible without hardening caused by temperature drop and the water is activated to move swiftly in the lines to cause uniform distribution. Thus, no partial shrinkage happens inside the noodle lines to prevent the lines from cracking on their surfaces.

Title: Band variable type timing reproducing circuit
Inventor: UCHIDA YOSHINORI
IPC: H03L7/06
Filed: 1979-07-13
Abstract: PURPOSE:To secure a continuous change for the equivalent noise band width of the PLL, by adding the AGC in front of the PLL circuit and then setting the band of the AGC substantially equal to the lead-in frequency range of the PLL. CONSTITUTION:AGC12 is added in front of PLL circuit 11. And now if no synchronism is secured for the PLL loop, the output of mixer 7 for synchronous component becomes 0. At the same time, the output of adder 9 turns to output voltage -Vref of reference voltage generator 10, and amplifier 2 has the gain close to the maximum gain. If the synchronism of PLL11 is secured under these conditions, mixer 7 produces the output equal to the amplitude of the arrival signal. And the output of mixer 7 becomes equal to voltage Vref, and the gain of amplifier 2 is set so that the AGC control voltage may be 0. Then the band of AGC12 is set equal substantially to the lead-in frequency range of PLL11, and the AGC is actuated after lead-in of the PLL. Then the input signal to the PLL is reduced to secure the synchronous lead-in in a high speed and in a wide frequency range. Thus the equivalent noise band width can be changed continuously.

Title: Etching method of copper or copper alloy
Inventor: MIYAZAKI HIROSHI
IPC: H01L21/3065
Filed: 1993-04-16
Abstract: PURPOSE:To prevent the generation of a side-etching, by feeding O2 and N2 respectively in the ratios of their flow rates to that of SiCl4 which are present respectively in specified ranges, and by heating copper or copper alloy at a temperature preset in a specified range, and further, by performing the dry- etching of a copper film or copper alloy film while generating a plasma. CONSTITUTION:In an etching method of copper or copper alloy, air in an etching chamber is exhausted, and a reactive gas is made to flow therein. In this case, the ratio of the flow rate of O2 to that of SiCl4 is made to be 0.1-0.4. Also, the ratio of the flow rate of N2 to that of SiCl4 is made to be 0.3-0.6, and in these ratios the reactive gas is fed for a copper film to be etched. The pressure of the reactive gas is so adjusted by its exhausting quantity as to be kept at 0.5Pa. The discharge power of the plasma generated in the reactive gas is 400W (the power per unit area of an electrode is 1.3W/cm<2>), and the temperature of a substrate is 240-300 deg.C. As a result, it is understood that by the addition of N2 to the reactive gas a side-etching is reduced. The vertical processed shapes of a Cu pattern can be obtained in the flow rates of about 12sccm for O2 and about 22sccm for N2 respectively.

Title: Method of controlling concentration of concentrated liquid and apparatus for controlling concentration of concentrated liquid
Inventor: KOMATSUBARA YASUYUKI
IPC: B01D1/00
Filed: 1993-04-16
Abstract: PURPOSE:To control the concentration of a concentrated liquid without using a solvent densitometer and to prevent a large amount of a solute from being dissolved in solvent vapor due to excessive concentration by monitoring the temperature of heated vapor after heat exchange and controlling the operation based on the previously set temperature as a standard. CONSTITUTION:A steam concentrating apparatus has a heater 10, generates heated steam by heating clean water in a steam generating apparatus 9, and circulates the heated steam in a heat exchanger tube 11 in a concentration can 4 to concentrate the solution in the concentration can 4. Regarding this concentration controlling method for a concentrated solution, the temperature T2 of the heated steam is monitored by a thermometer 12. If, for example, a motor valve 8 is opened at the time, as concentrated solution discharge timing, when the heated steam temperature becomes 76 deg.C, the concentrated solution with 20% of water content can be discharged. Since the liquid surface level lowers when the concentrated solution is discharged, a liquid surface level sensor detectes that and opens the motor valve 14 and thus raw liquid with a high water content is supplemented. As a result, excessive concentration of the concentrated solution is prevented and liquid to be discharged at a constant temperature is taken out.
