Title: Signal identification system
IPC: H04B10/2507
Filed: 1992-03-19
Abstract: PURPOSE:To suppress the error of identification and to improve reliability by detecting the peaks of the levels '1' and '0' of an equalization wave-form inputted to an identification circuit and superimposing their average value to a constant identification level. CONSTITUTION:Peak detection circuits 12 and 13 respectively detect the peak levels in the signal levels '0b and '1', a first adding circuit 14 adds the peak levels in the signal levels '1' and '0', and a dividing circuit 15 divides the output value of the circuit 14 into two. Both of the circuits 14 and 15 obtains the average level of the peak level in the signal levels '0' and '1'. A second adding circuit 16 adds the constant identification level and the average value of the peak levels to control the identification level of the identification circuit 9. As the output of the circuit 15 is the instant value of the average value of the levels '1' and '0', the identification level is always the intermediate value between '0' and '1' even in the case of the code of which mark rate in not 1/2. Thus, data output generating few errors even to the signal with an optional mark rate is obtained.

Abstract: PURPOSE:To reduce parking space by dividing a crank arm into a crankshaft fixing section and a pedal arm fixing section for a screw joint, and twisting the pedal arm section by 90 degrees. CONSTITUTION:The torsional turn of a pedal arm 4 is prevented by the pressed engagement of the pyramid end 10 of a crank arm turning section 18 and a compression spring 9. When a bicycle is parked, the spring 9 is compressed by operating a stopper 8 using fingers, a control knob or the like, until the pyramid end 10 is released. Thereafter, the spring 9 is coupled to a foot stopper 8, thereby ending a pedal shrinkage operation. Before travel, a foot pedal 1 in parking state is twisted by 90 degrees and turned. The pedal 1 can be thereby restored to a normal travel condition.

Title: Ofdm system and ofdm equipment
Inventor: HIRONO JIRO
IPC: H04N5/00
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent a permanent reception disable area due to multipath distortion in a service area in the orthogonal frequency division multiplex(OFDM) broadcast network system employing a distributed transmission system. SOLUTION: Transmission frequency of other transmission stations is deviated by Δf1, Δf2 with respect to a transmission frequency (reference frequency) of a reference transmission station. In this case, even when frequency characteristics of a received electric field at an optional point in a service area are cancelled together for a moment, since vectors of other two arrived signals are rotated by 2πΔAf1t, 2πΔf2t with respect to the vector of the incoming signal, the cancelling relation does not continue permanently. Thus, there is not permanently reception disable area due to multi-path distortion in the service area.
