摘要： PROBLEM TO BE SOLVED: To improve efficiency of forced air-cooling for a printed circuit board of a printed circuit board assembling component built in an outdoor communication device. SOLUTION: A space 47 in a casing 40 is divided into a space 57 and a space 150 by a motor fan component 60, and the space 57 and the space 150 are communicated through an air channel 72. A printed circuit board assembling component 101 is disposed under the motor fan component 60. When motor fans 61, 62 are driven, the motor fans draw in air from below, send the air to the space 57 and then blow the air to the lower portion of the printed circuit board assembling component 101 through the air channel 72. The blown air is raised inside the printed circuit board assembling component 101 and forcibly cools printed circuit boards 102, 103, 104.

CONSTITUTION:A presser 1c is provided to press a cable 2, which is inserted into a cable holder 1a as pressed by a set screw 1a-1 screwed into the top of cable holder 1a, against a cable support piece 3. Therefore, the cable 2 is clamped through such a manner that the presser 1c can be set adjustable in position along a pressing direction by driving the set screw 1a-1 in or out in the direction shown by a narrow C, so that the cable 2 which is different in outer diameter but can be inserted into the cable holder 1a can be freely pressed against the cable support piece 3 and held. A mounting leg 1b of the cable holder 1a is provided with a hook 1b-1. Therefore, the hook 1b-1 is mounted on the cable support piece 3 at an optional spot, to clamp the cable 2, and the cable clamper 1 is fixed at the spot concerned.

摘要： PURPOSE:To mount a prescribed number of printed boards in parallel inside the basket body by bendably fixing corner stacks holding both corners of the lower part of a printed board between to a basket body in a state of being sequentially piled in multistages and combining a desired number of corner stacks. CONSTITUTION:A shaft pin 31 of a hinge 30 is leveled, a plane of one side swing plate 33 is stuck to a base of a corner stack for being fixed to the corner stack 10 using a machine screw 35. Then, a plane of the other side swing plate 32 is stuck to a side wall surface of a basket body 1 to be fixed to the basket body 1 using the other machine screw 35. Almost one side of a fixing plate 40 is close to the upper of the side of the corner stack 10 and the other side is surely fixed to the corner stack 10 in a state of being aligned with the corner stuck 10 so that the other side may project outside the corner stack by using a machine screw.

摘要： PURPOSE:To prevent the malfunction of a signal receiver due to impulsive oscillation or the like by combining each reception signal frequency with the detected and delayed signal logically to stop the start output of a local station selecting signal detecting circuit. CONSTITUTION:Frequency signals different from one another received in serial successively are processed by a read filter 1 or 11, a detecting circuit 2 or 12, and a delay circuit 3 or 13, and detected and delayed group and individual signals are supplied to pulse generating circuits 4 and 14. Pulses generated from circuits 4 and 14 in accordance with these signals which do not overlap with respect to time are applied to a local station selecting signal detecting circuit 5, and a local station selecting signal is outputted from the circuit 5. Detected and delayed group and individual signals are subjected to AND processing by a pulse generating circuit 6, and a pulse corresponding to AND from the circuit 6 becomes the signal which stops the start of the circuit 5, and the occurrence of the malfunction of the signal receiver using read filters is prevented even if microphonic noise due to impulsive oscillation occurs.

摘要： PURPOSE:To attain normal reception and decision of a fault by utilizing a leakage component of a transmission output sent from a transmission section so as to decide a fault of 1st and 2nd receivers simultaneously and sending the result of decision. CONSTITUTION:A reception signal is fed to the 1st receiver 31 or the 2nd receiver 32 via a reception changeover switch R-SW to improve the input signal level of the receiver by 3dB than a conventional transmitter-receiver and the signal is inputted to the receiver while keeping nearly the level received by the antenna. Since the simultaneous reception by the 1st and 2nd receivers 31, 32 is disabled, the decision of a fault of the receiver by the comparison of the squelch voltage is not attained. Then power is applied to the 1st and 2nd receivers at all times and when a transmission section 2 is started by a transmission instruction, the leakage component of the transmission output sent from the transmission section is received by the two receivers to compare the squelch voltages for fault decision. Thus, normal reception and fault decision are attained up to a predetermined minimum reception level.

摘要： PURPOSE:To prevent abnormal picture transmission during turning of a camera by receiving a mobile signal representing the turning or stop of the camera and inhibiting the write to a memory during the turning. CONSTITUTION:A signal for one patterns's share of a picture from a TV camera 1 is A/D-converted in high speed by an A/D converter 2 and written in a buffer memory 3. Then the signal is read at a low speed under the control of a control circuit 8 from the memory 3, a difference is calculated at a DPCM modulation circuit 5, the band is compressed, an obtained parallel signal is converted into a serial signal train by a P/S converting circuit 6, a carrier is modulated by a modulator-demodulator circuit 7 and transmitted to a line 4. In order to control the write to the memory 3, a mobile signal representing the turning or stop of the camera 1 is inputted to the control circuit 8, the write command from the control circuit 8 is inhibited during the turning of the camera so as to stop the write during the turning.

摘要： PURPOSE:To achieve smooth observtion or control without interference during the obseravtion or control, by providing a function which gives a response signal unless the station itself is busy, with a processor of a monitor controller of a master station. CONSTITUTION:In a radio remote monitor control system consisting of two master stations and a plurality of slave stations in which the transmission frequency and the reception frequency are the same, when one master station makes monitor or control of a slave station, the tansmission of another master station is inhibited. In this case, when one master station makes monitor or control of the slave station by a monitor controller 1, a lock signal is transmitted for a short time by using the clock of a clock section 2 in advance and it is confirmed that another master station is not during transmission with the presence of the response signal from another master station and the transmission is inhibited to another master station.
