Abstract: PURPOSE:To prevent the deterioration of quality of analog signals caused by the digital signals for an equipment where the signal systems are mixed together. CONSTITUTION:The N-bit digital signals to be transmitted for each word are successively latched by an N-bit data latch 6 for each word at the transmitter side.

Abstract: PROBLEM TO BE SOLVED: To allow even an inexperienced person or a weak-sighted person to easily measure the proportion of rice and water by using one measuring cup alone in the preparation for cooking rice during which rice is washed and a proper mount of water is applied to a rice cooker. SOLUTION: A measuring cup 1 comprises a freely expansible bellows 2C which enables a container 2 to switch the amount of rice and the amount of water as single unit. With the bellows 2C reduced to the minimum, the total capacity is made enough to weigh 1 go (0.18039 l) of rice and with the bellows 2C expanded to the maximum, the maximum capacity allows the weighing of the proper amount of water for this capacity of the rice. These two applications are possible by the container 2 as single unit. In this container, a filter having numerous pores bored there through is positioned and engaged at an intermediate point of an opening part of the container 2 as single unit and the bottom part thereof. The capacity of 0.18039 l of the rice is determined by the capacity of the opening part and the filter.  In the weighing of water, a switched capacity can be produced for the amount of rice by arranging an area from the opening to the bottom part of the container through the pores of the filter.
