    摘要： A power line communication system which enables high quality communication utilizing a pair of power lines connected to a vehicle mounted battery, has a pair of communication lines connected to a pair of power lines, respectively, to communicate a high frequency signal of 1 MHz or more. This system has a balance filter which is interposed between each of the communication lines and a vehicle mounted communication apparatus, the filter, a circuit configuration of which is formed in balance type. The communication system also has a pair of electrically balanced lines which are connected between the balance filter and each of the communication apparatuses and are power-fed from the battery, for performing communication between the communication apparatuses.

    摘要： In a decoding system having a cache memory, for decoding a variable length code such as a MH code, the decoding is carried out by accessing the cache memory by using a variable length code as an address. Whether the cache memory is hit or mishit is judged by discriminating whether or not the code bits of the 7 bits succeeding to the firstly appeared “1” in the actual code is coincident with the tag stored in the cache memory. This comparison is carried out by masking bits other than an effective bit length of the actual code, by utilizing the three-bit information indicating the number of remaining bits in the actual code, succeeding to the firstly appeared “1”, outputted from the cache memory. Thus, the decoding system is capable of elevating the hit rate of the cache memory.

    摘要： Disclosed is a piezoelectric resonator device. This piezoelectric resonator device comprises a piezoelectric substrate having an almost rectangular plane shape. The piezoelectric substrate is provided with a slit extending to the inside from one edge of the piezoelectric substrate, for forming a tuning fork portion, and a pair of slits for separating the tuning fork portion, spaced apart from the slit forming the tuning fork portion by a predetermined distance on both sides of the slit forming the tuning fork portion, and approximately parallel with the slit forming the tuning fork portion. Vibrating electrodes are formed on both major surfaces of the piezoelectric substrate at a piezoelectric vibrating portion, between the slits separating the tuning fork portion from non-vibrating portions of the substrate.
