Title: Humidity sensor
Inventor: SUZUKI TATSUYA
IPC: G01N27/12
Filed: 1990-11-27
Abstract: PURPOSE:To detect steam in a wide temp. region with high sensitivity by mutually negating the sensitivity of a humidity non-sensitive resistor element and that of a humidity sensitive resistor element to org. gas. CONSTITUTION:A humidity sensitive resistor element 1 sensing both of steam and org. gas and a humidity non-sensitive resistor element 2 sensing the org. gas but not reacting with steam are provided to a humidity sensor A. These elements 1, 2 are combined with resistors R3, R4 to constitute a Wheatstone bridge and AC voltage 5 is applied across both terminals P, Q and the potential difference between the intermediate point M of the elements 1, 2 and the intermediate point N of the resistors R3, R4 is detected by the ammeter 4 provided between the intermediate points M, N and steam is sensed. The values of the resistors R3, R4 are adjusted so that the sensitivities of the elements 1, 2 to the org. gas are well-balanced. Therefore, the sensor A generates no potential difference between the intermediate points M, N in an org. gas atmosphere and only the element 1 senses steam in a steam atmosphere and potential difference is generated between the intermediate points M, N to be detected by the ammeter 4.

Abstract: PROBLEM TO BE SOLVED: To increase the out-of-band roll-off and to reduce the inter-symbol interference(ISI) by applying a shaping function to every extension block when a block is generated for the orthogonal frequency division multiplex(OFDM) data. SOLUTION: An S/P converter 502 converts a serial input data stream into N pieces of parallel streams of a composite symbol X(n) as X(n)=Xr(n)+jXi(n): n=0,... N-1. Then the fast inverse Fourier transform 504 is applied to N pieces of symbol streams. A periodical prefix adder 506 adds the extension parts to both sides of an acquired data block. A block shaping part 507 applies a shaping function (e.g. a raised cosine shaping function) to every extended block in place of a conventional rectangular window. A guard interval adder 508 adds a guard interval between extended blocks. Then a P/S converter 510 converts a parallel data stream into a serial data stream, and a D/A converter 512 converts the serial data stream into the analog signals.
