Title: Data checking circuit
Inventor: KISHIMOTO KAZUO
IPC: G06F11/00
Filed: 1980-07-22
Abstract: PURPOSE:To exactly detect an error of a data, by comparing the contents of a data on a bus line with those of the previous data which has been outputted to this bus line. CONSTITUTION:A logical operation circuit 2 sends out a data onto a bus line 1 through a controlling circuit 3, and also supplies this data to a dissidence detecting circuit 4. When the circuit 3 has sent out a data onto the bus 1 by a control signal 3a, other data channel 6 also sends out a data onto the bus 1, and as a result, the data on the bus 1 interfere with each other and become other data. The circuit 4 compares the data of the circuit 2 and the data on the bus 1, corresponding to a bit, therefore, when dissidence of both the data has been detected, a signal 4a is outputted. By the signal 4a, an outputting circuit 5 outputs a signal 5a informing that an error has been generated in the data, in accordance with a control signal 5b.

Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To obtain a processed gostrodiae tuber food with improved flavor of gostrodiae tuber, and to provide a method for producing the same. SOLUTION: This processed gostrodiae tuber food is obtained by several different methods. For example, the carbohydrate, e.g. starch, present in the gostrodiae tuber extract is saccharified by the aid of enzyme or microorganism into a sweetener. The saccharified liquid may be fermented into alcohol in the presence of mold into an alcoholic solution. The alcoholic solution may be further fermented in the presence of acetic bacteria into an acidifier with gostrodiae tuber components and improved gostrodiae tuber flavor. Thus, various characteristic processed gostrodiae tuber foods, e.g. sweetener, alcoholic solution and acidifier, are obtained at different stages of the enzyme- or microorganism- aided process. The processed gostrodiae tuber foods are expected to exhibit the effects inherent to natural gostrodiae tuber, and useful for various foods, e.g. health beverages and seasonings.
