Title: Broadcast wave receiver for ofdm system
Inventor: YAMAUCHI KEIICHI
IPC: H04J11/00
Filed: 1995-02-20
Abstract: PURPOSE: To automatically discriminate the band width of received signals and to perform appropriate reception by transmitting broadcast waves provided with a null part for which the carrier wave signals of a prescribed level are inserted for the respective frames of data signals. CONSTITUTION: A null detection part 21 detects the null part in the received data signals from the envelope of the signals and generates null detection signals. When the generation of the null detection signals is discriminated, a control part 19 commands the start of a band judgement operation to a band judgement part 20. When the operation is started, the band judgement part 20 discriminates whether or not the carrier wave signals are present in a prescribed frequency among the output signals of a fast Fourier transform device (FFT) 12. Then, narrow band detection signals are outputted to the control part 19 when the carrier wave signals are present and wide band detection signals are outputted to the control part 19 when they are not present.  The control part 19 controls the demodulation operation of the FFT 12 corresponding to the discriminated result of the band judgement part 20. Thus, whether the received signals are the signals of a wide band or a narrow band is automatically discriminated and the appropriate reception is performed.

IPC: F16B15/08
Filed: 1988-02-15
Abstract: PURPOSE:To prevent a fastener from blocking by forming a projecting piece which projects sideward for locking a base at one, at least, of side edges of the base in the holding band of the fastener. CONSTITUTION:In addition to the usual holding band 1 of a fastener, projecting pieces 16 projecting sideward for locking a base are formed at the side edge of the base. The projecting piece 16 for locking the base has a function in which the piece is locked with the guide 17 of a tool to keep the base in a constant position. As a result, even if a blade 7 is driven in a fastener 2 in the driving room 6 of a nose 5 as an object, the base is kept by the guide 17 of the nose 5 not to incline. Accordingly, it is eliminated for the fastener 2 to incline its position in the driving room 6 of the noise or its passage so that the fastener can be prevented from blocking.

Abstract: PURPOSE:To obtain an always stable air-conditioning state avoiding the nonuniformity of the temperature in a structure, by setting a pressure adjusting blower on an open air supplying duct on the air inlet side of an air conditioner. CONSTITUTION:The air inlet side of the fan 3a of the air conditioner is equipped with an air-conditioning coil 3b. The supplying duct 2 on the air inlet side of the air conditioner 3 is equipped with a pressure adjusting blower 4, and the internal pressure in a diaphragm structure 1 is changed and kept by controlling the rotational frequency of the blower adequately. Open air transmitted from the left end of the open air supplying duct 2 is conducted to the blower 4 through a damper 5 and is air-conditioned by a coil 3B and blows into the diaphragm structure 1 with the fan 3a. The air in the diaphragm structure is conducted to the supplying duct 2 through a return duct 2a and is conducted again to the diaphragm structure 1 and circulates in the structure and ducts. When the air quantity in the diaphragm structure 1 is increased and the internal pressure is reduced, then the rotational frequency of the blower 4 is increased. When the internal pressure exceeds a set value, the rotational frequency of the blower 4 is reduced and the open air supplying quantity is reduced.
