Title: Error correction encoding frequency hopping spread spectrum communication system
Inventor: FUKUMASA HIDENOBU
IPC: H04W84/12
Filed: 1993-12-10
Abstract: PURPOSE:To provide an error correction encoding frequency hopping spread spectrum communication system which can transmit a large amt. of information with high reliability with limited transmission power and in limited frequency bands. CONSTITUTION:An encoding means 40 branches input data D40 into first to N-th data D401-D40N. Redundancy for correcting errors is given to branched data D401-D40N and first to N-th diffusion means 411-41N execute frequency hopping in respectively different N-pieces of hopping patterns HP1-HPN. The data D411-D41N are modulated and synthesized in terms of a carrier by a synthesis means 42 and they are radiated as radio waves R10. The radio waves 10 are inversely diffusively modulated by the similar hopping patterns HP1-HPN in first to N-th inverse diffusion means 431-43N. A decoding means 44 obtains original data by correcting the error by using redundancy included in inverse diffusion data D421-D42N.

Title: Ptc plate heater
Inventor: TOYAMA MASAHITO
IPC: H05B3/14
Filed: 1988-12-07
Abstract: PURPOSE:To obtain a PTC plate, in which only one side thereof is heated, suitable for such as a print press-heater by making heat conduction coefficient of an insulation layer located on one side of a heating device with a positive temperature coefficient smaller than that of an insulation layer located on the other side thereof. CONSTITUTION:A voltage is applied across electrode plates 15 and 16 constituting a pair to energize a heating device 13 with a positive temperature coefficient. The device 13 then generates heat. The heat is transferred to radiation plates 19 and 20 through the electrode plates 15 and 16 and insulation layers 17 and 18. Thus, an object to be heated such as clothes is heated by the heated radiation plates 19 and 20. In this case, the heat conduction coefficient of the insulation layer 17 located one side of the heating device 13 with a positive temperature coefficient is made large to transfer heat easily. While, that of the insulation layer 18 located on the other side is made small to transfer heat hard so as to shut off heat radiation there. Accordingly, heat is transferred almost in one direction and the one side mainly generates heat. Therefore, a PTC plate heater suitable for such as a print press heater is obtained.
