Abstract: A received pulse signal based on an on-off keying modulation scheme is alternately sampled by AD conversion sections operated by a clock signal whose frequency is one-half of a transmission rate. In the synchronization, amounts of delay in sampling timing adjustment sections are made different from each other, whereby phases of two different points in a symbol pulse are sampled. An amount of delay in a variable delay section is adjusted in accordance with a result of comparison of the sampled values, thereby achieving synchronization. At the time of demodulation, the amount of delay in the variable delay section is held, and the amounts of delay in the sampling timing adjustment sections are switched to the same value, and the symbol pulse is alternately sampled. The sampled values are subjected to threshold value determination, and the determination result is subjected to parallel-to-serial conversion, whereby a demodulation output is acquired.

Abstract: The present invention has an object to provide a wireless apparatus which is capable of correctly sampling a waveform of a pulse even when a shape of the pulse is varied. A synchronizing apparatus for causing an input signal to be synchronized with a clock signal is equipped with sampling unit 102, 103, and delay control unit 112. The sampling unit 102 and 103 sample the input signal at first sampling timing and second sampling timing, which are separated from each other in a predetermined time interval. The delay control unit 112 shifts both the first and second sampling timing during synchronous pull-in operation, and also, narrows the interval between said first and second sampling timing during synchronous follow-up operation. A synchronous status judging unit 105 judges whether or not the input signal is synchronized with the clock signal based upon a phase error amount outputted from a phase error calculating unit 104, and outputs the synchronous status to a delay amount control unit 106.

Abstract: A pulse signal reception device of a comparatively simple configuration detects a signal sampled at an optimal clock timing for a pulse modulation signal having a signal width shorter than a symbol frequency. In this device, a time division unit (103) samples a data signal at a clock signal rise edge and outputs the sampled data signals to counters (104-1 to 104-3), respectively. The counters (104-1 to 104-3) count the number of High levels when the data signal becomes High level within a predetermined period, and a maximum value detection unit (105) outputs maximum data string information on a data string counted by a counter in which the maximum number of High levels has been detected among the counters (104-1 to 104-3) to a selection data judgment unit (106). The selection data judgment unit (106) judges which data string sampled at a particular timing is to be selected as a demodulation data string.

Abstract: A pulse transmitter having a relatively simple structure and generating a pulse modulating signal even at a high transmission rate. In the pulse transmitter, a symbol pulse generating part (103) generates a symbol pulse of amplitude level ? when data S1 is “0,” and that of amplitude level &ggr; when data S1 is “1” in the first pulse slot section, the data pulse generating part (104) generates a data pulse of amplitude level 0 when data S2 to Sn is “0,” and that of amplitude level ? when data S2 to Sn is “1” in a later pulse slot section. The relationship of the amplitude levels keep the relation ?<?<&ggr. An adder (105) adds the symbol pulse and the data pulse and outputs the sum as a pulse modulating signal.

Abstract: A bookbinding apparatus includes a collecting device, a bookbinding path, a bundle conveying device for transferring the sheet bundle to a paste applying position and then to a cover binding position, a paste applying device for applying an adhesive to a spine part of the sheet bundle, and a cover feeding path. A cover binding device binds the sheet bundle with the adhesive to the cover sheet, and a cover binding control device controls the cover binding device.

The cover sheet is sandwiched between the back abutting plate member and the spine part of the sheet bundle with a small gap between the back abutting plate member and the spine part. The cover binding control device adjusts a size of the gap depending on a thickness of the cover sheet when folded back.

Abstract: It is an object of the invention to provide a variable delay apparatus in which, even immediately after the delay amount of the variable delay apparatus is changed, a signal of a timing that is different from a set delay amount is not output. The variable delay apparatus of the invention includes: a variable delay block 108 having N (N is a natural number) delay elements 101a to 101n, and N selectors 102a to 102n; a variable delay block 109 having N delay elements 103a to 103n, and N selectors 104a to 104n; and a selector 107. After selection signals 105a to 105n and 106a to 106n are changed, and after an output timing of a delay amount set by the variable delay blocks 108, 109 is attained, the signal to be output is switched by the selector 107, thereby avoiding a situation where, immediately after the delay amount is changed, a signal of a timing that is different from the set delay amount is output as an output signal.

Abstract: A pulse transmitting device is provided to avoid interference between pulses due to multipath influence even in a high speed pulse transmission that is typical of a UWB by making use of a relatively simple method and to improve receiving quality. In the device, a pulse adjusting unit (110) generates pulses in response to transmitting data, a non-use interval setting unit (120) sets up a non-use interval where the pulses generated by the pulse adjusting unit (110) are not transmitted on the basis of a delay time that a delayed pulse caused by the multipath delays from a main pulse and takes until arriving at a communication partner. A pulse position adjusting unit (130) adjusts a pulse position not to transmit the pulses during the non-use pulse interval. An RF transmitting unit (140) converts the pulse, the position of which is adjusted by the pulse position adjusting unit, to a wireless frequency band and transmits a pulse wireless signal after the conversion to the communication partner.
