Filed: 1989-08-22
Abstract: PURPOSE:To suppress error rate below a definite value independently of a communication state by constituting a normal mode and a fall back mode so as to be capable of being switched, and changing the length of picture data by a prescribed means according to these modes. CONSTITUTION:The output of a variable length encoding circuit 6 is inputted to an error correction encoding circuit 7, and the error correction encoding circuit 7 adds an error correction code to the variable length encoded picture data. Error correction code length is changed by a normal/fall back mode selection signal, and it is constituted so as to be short at the time of the normal mode and to be long at the time of the fall back mode. Then, when the communication state is aggravated, the mode is changed into the fall back mode. In the fall back mode, the picture data is shorter compared with the normal mode, and the error correction code can be made longer by this portion. Thus, the error rate can be suppressed low.

Filed: 1984-10-17
Abstract: In a measuring instrument for measuring the relative position of two objects, the graduation of a scale as well as a number of identical reference marks absolutely positioned with respect to this graduation and associated code marks are scanned by a scanning unit. The periodic scanning signals obtained in the scanning of this graduation are transferred via first signal lines, and the reference signals obtained in the scanning of the reference marks are transferred over a second signal line to an evaluating arrangement. Code signals obtained in the scanning of the associated code marks by the scanning unit are also transmitted over the second signal line to the evaluating arrangement. The reference signals and the code signals on the second signal line are distinguished from one another by means of AND gates which ensure that the reference signals and the code signals are present on the second signal line only during respective predetermined signal states of the periodic scanning signals.

Abstract: PURPOSE:To attain a uniform temperature distribution over a work piece by providing a device that feeds waves into a cavity resonator which is formed of an oval mirror and a circular screening plate located in the end portion inside the oval mirror enclosing the first focus. CONSTITUTION:A plasma lamp 6 is placed at the first focus of an oval mirror 1 and a circular screening plate 8 of wire mesh that screens waves is placed in the end portion of the oval mirror.
