摘要： PURPOSE:To provide a magnetic recording and reproducing device capable of performing an excellent reproduction of a part for which an insert recording was performed even when an unrecorded part exists on a magnetic tape in the insert recording in which a recorded part on the magnetic tape is replaced with a new video signal. CONSTITUTION:At the time of an insert recording, the presence or absence of a control signal to be reproduced from a magnetic tape 11 is discriminated in a control signal discrimination circuit 6 by a control head for reproduction 1. When the control signal is judged as the absence, the information is supplied to a control circuit 5 and an alarm output circuit 7. In a control circuit 5, the control signal synchronizing with a video signal to be recorded is generated, the signal is recorded on a magnetic tape 11 via a control head for recording 3 and at the same time, the magnetic tape 11 and a video head 10 are controlled via a drive circuit 8.

摘要： PURPOSE:To improve the throughput of an information processing system having an error detecting and correcting circuit by adding an inhibiting circuit for the error detection and correction to every area of a storage device so that the error detection and correction can be inhibited in an area in which the error detection and correction are unnecessary. CONSTITUTION:A register 61 in an error detecting and correcting circuit 60 corresponds to each divided area of an area of a storage device 50, and in a register corresponding to an area for inhibiting the error detection and correction by a register contents setting instruction from a CPU 10, an H level is stored. Also, a decoder 62 inputs an address signal 70 from the CPU 10, decides to which area of the device 50 the transfer is executed, and sets a flag corresponding to the area to which the transfer is executed to an H level. Subsequently, in accordance with an L level or an H level of an output of the register 61 corresponding to the flag of an H level of the decoder 62, an error detection/correction inhibiting signal 66 becomes an L level or an H level, and data outputted from the CPU 10 is inputted to the device 50 through an error detection inhibiting circuit 30 or without passing through its circuit. In such a way, the throughput of the information processing system having the circuit 30 can be improved.

CONSTITUTION:An inside and outside air selector case 1 respectively opens an outside air introducing port 2 to a top wall 1a, inside air introducing port 3 to a side wall 1b and a bellmouth 5, serving as the suction port communicating with a scroll casing 4, to a bottom wall 1c while provides an inside-outside switching damper 6 in the inside. While the scroll casing 4 provides in its inside a centrifugal fan 8 being mounted to a blower motor 7 on its rotary shaft 7a. In this constitution, an air outflow side end part 5a sets its bore diameter D5 in the bellmouth 5 equivalent to or not less than the outside diameter D9 of the centrifugal fan 8. Thus increasing a flow path area of the bellmouth 5 decreasing a resistance loss of ventilating air, the air amount-air pressure characteristic of a blower device is improved.
