Title: Data transmission device
Inventor: UESUGI MITSURU
IPC: H04L27/32
Filed: 1989-02-01
Abstract: PURPOSE:To raise an improvement factor of an error rate from hard decision Viterbi decoding and an improvement factor from Viterbi decoding by executing soft decision Viterbi decoding by utilizing a fact that it is possible to have a soft decision value as decoding data, when differential coding is performed before a GMSK (or MSK) modulation. CONSTITUTION:When data from a voice CODEC, etc., of a transmitting side is received, a data interface 1 sends it to a convolution encoder 2 and performs convolutional encoding. This data is brought into differential encoding by a differential encoder 3, and a signal modulated by a GMSK modulator is radiated as a radio wave from a transmitting antenna 5. A detecting signal which passes through a receiving antenna 6 and an orthogonal detector 7 outputs a same phase component 8 and an orthogonal component 9. A DFE 10 outputs a soft decision value 11 from the detecting signal. A bit clock reproducing device 17 reproduces a clock from a receiving signal, and outputs it to a bit coefficient generator 12. The generator 12 outputs a bit coefficient 13, based on information from the reproducing device 17. By multiplying the coefficient 13 and the decision value 11, soft decision decoding data 14 is obtained.

Abstract: PURPOSE: To keep desired height unchanged by pressing an operation member for vertically moving and positioning an armrest member at the desired height, and then releasing the operation member from a pressed state. CONSTITUTION: A front plate 42 and the front side 42a thereof are kept in a pressed state, so as to be approximately flush with the external surface of a cylindrical body 22 against the resilient force of a spring 45 laid between the reverse side of a rear plate 43 and the counter sunk section 25a of the body 22. Then, in this pressed state, the cylindrical body 22 of an armrest member 2 is coupled to an armrest support member 1 from a lower position, and moved down along a gap between the engagement notches 12 of the member 1, so as to keep the coupling piece 44 of an indirect plate 41 free from contact with the notches 12. For the adjustment of the height of an armrest 21, the front plate 42 of an operation member 4 is pressed to disengage the piece 44 from the notches 12. In this state, the armrest member 2 is moved up or down, relative to the support member 1.  When the armrest 21 comes to desired height, the front plate 42 is released from a pressing force. As a result, the piece 44 comes to gear with the notches 12 at a level suitable for the desired height, due to the resilient force of the spring 45. Also, when the piece 44 does not come to gear with the notches 12, the member 2 is moved slightly up or down to keep the piece 44 and the notches 12 in an engaged state. As a result, the armrest 21 is fixed at height corresponding to the engaged state.
