Title: Spread spectrum polyphase modulation/demodulation method
Inventor: ANDOU NORIHIRO
IPC: H04B1/707
Filed: 1993-11-16
Abstract: PURPOSE:To solve a problem of making information hard to discriminate due to an exponential increase of code points to decrease distance between each other of code points by increasing the number of information bits in polyphase modulation. CONSTITUTION:Serial transmission data SD (...101...) is converted to parallel data by a serial-parallel converter 1, and three ((n) in general) parallel bits 1, 0 and 1 are inputted to information spreader 2, 3 and 4, respectively, and the information (spectrum) is spread by using spread codes A, B and C. Spread data (a), (b) and (c) are added by an adder 5 at each bit, ad each bit is changed to multi-valued data (s) with four values. The information diffusers 2, 3 and 4 output the spread codes as they are when input data is 1, while outputs then by inverting 0, 1 of each bit when it is 0. The multi-valued data (s) is inputted to a modulator 6, each bit converted into parallel data, and the phase shift quantity of a carrier are set at 0, pi/2, pi, -theta/2 corresponding to the values 0, 1, 2 and 3 of each bit of the data (s). On the demodulation side, multi-valued data s' is obtained through plane detection, the correlation of the data s' with each spread code is detected, and transmission data 1, 0 and 1 are restored.

Title: Wire stretching device
Inventor: TAKEDA AKIKAZU
IPC: H01T19/00
Filed: 1986-12-03
Abstract: PURPOSE:To stretch a wire linearly by providing a rotary gear, a rack gear which engages it, and a compression spring which presses the rack gear with constant force integrally to a reel to which one terminal of the wire is fitted. CONSTITUTION:The compression spring 6 presses down the rack gear 4 with the force F2, so two forces F1 and F2 in mutually opposite upper and lower directions operate on the rack gear 4 at the same time. In this case, the F1 which draws the rack gear to the wire is larger than the force of F2 of the compression spring 6 and the rack gear 4 is elevated as shown by an arrow. The rack gear 4 moves against the force of the compression spring 6, which receives and stores a compressive force as a restoring force. Here, the wire 7 is unwound from the reel 2 and then the rack gear 4 can not be elevated even if the rotary gear 3 more at the end of the elevation of the rack gear 4 by the rotation of the rotary gear 3 united with the reel 2; and only the teeth 4a at the lowermost part contacts the rotary gear 3, which draws the wire 7 out while idling.

Abstract: PURPOSE:To make it possible to respond promptly to an uncontrollable state of a gas proportional valve by arranging a block solenoid valve to close immediately regardlessly of a drive signal when said gas proportional valve turns uncontrollable even if said solenoid valve is opened by the drive signal. CONSTITUTION:When a terminal section of a transistor Q1 of a gas proportional valve coil DVL turns uncontrollable due to grounding or the like, comparation voltage is made lower than reference voltage due to the dimensions between the comparative voltage in a comparative voltage inlet section (+) and the reference voltage in a reference voltage inlet section (-) of an operational amplifier ICI in a voltage detection circuit 2 and a low level of detection signal is given to a block solenoid drive circuit 3 from a voltage detection circuit 2. Then, a transistor Q1 in a block solenoid drive circuit 3 is turned off by the detected signal even when the transistor's base receives a drive signal to open the block solenoid valve by way of an inversion circuit IV, which forces the block solenoid valve to be closed and stops the supply of gas to a gas supply pipeline.
