Title: Rotator unit equipped with multiple-stage fan
Inventor: KUBOYAMA NOBUYOSHI
IPC: F24J3/00
Filed: 1984-03-21
Abstract: PURPOSE:To contrive to improve the heat generating effect by a structure wherein two or more rotary bodies are provided in a cylindrical casing equipped with a gas suction port and a gas exhaust port and one or more rotary bodies are rotated in the direction of rotation different from the direction of rotation of the remaining rotary bodies and at the same time frictional heat generating parts are formed through minute gap in the rotational zone of each rotary body. CONSTITUTION:The fans 1b of respective rotators 1 are respectively driven by electric motors 1a in the directions different from each other (in the direction indicated by the arrows). Because the two fans 1b, the direction of inclination of which are the same, rotate in opposite directions, the air locating between the two fans 1b turns to be sucked by both the fans 1b, resulting in allowing for the amount of both the fans 1b to suck through the gas suction port 4 and deliver through the gas exhaust port 5 of a cylindrical casing 2. Because the frictional action of gas by the both rotary bodies is caused by the rotation of fans 1b in opposite directions, the frictional heat generating effect at frictional heat generating parts becomes extremely large. Accordingly, the thermomotive action is remarkably quick and effective. Because the air stagnant between the both fans 1b is also subject to frictional action in the state under reduced pressure, said air similarly initiates to produce heat.

Abstract: PURPOSE:To realize a linear time counter while making fast feeding and fast rewinding operations by winding a magnetic tape around a cylinder to make possible reading out of line signals by a magnetic head and providing the device with a means capable of measuring the traveling length of this tape. CONSTITUTION:A tension post 11 is constituted so as to be movable in a direction A and to avoid sliding contact with the magnetic tape 35, a stationary guide 10, an impedance roller 9 and a capstan shaft 3a.

Taking up of the tape 35 at the time of fast feeding and fast rewinding is executed by taking up the tape 35 by using the torque directly generated in a capstan motor 3 without the aid of the torque limiters of reel turntables 4, 5. The taking-up speed of the tape 35 is increased in such a manner, by which the fast feeding and fast rewinding at a higher speed are made possible. Further, linear time counter capable of measuring the traveling length of the tape 35 is realized if recording and reproducing of the prescribed signals by a rotary head are possible at the time of FF/REW.

Abstract: PURPOSE:To automatically eliminate a commercial, etc., by outputting a command signal based on a specified mode discriminating signal corresponding to a sound mode and stopping a recording operation of a receiving signal upon noncoincidence between an output level of this command signal and an output level of the sound signal mode. CONSTITUTION:When a TV signal is turned into other broadcasting mode than the stereo broadcasting, 'L' signal is led to a terminal (a) of a changeover circuit 6, and the command signal S3 of 'L' is outputted from an output terminal (o). Then, when this command signal S3 is given to a gate circuit 5, it is inverted by an inverter 5a, and the command signal of 'H' S3 is given to the other input of an OR gate 5b. By this method, since an output of the gate circuit 5 is turned into a control signal of 'H', a control signal for instructing a magnetic recording signal processing circuit and mechanical servo control circuit to make a pause in the recording is outputted by a control circuit 4 upon receipt of this 'H' signal. By this method, the recording is made to pause, and hence the recording to a video tape is put under pause accordingly.

Filed: 1983-03-29
Abstract: PURPOSE:To achieve the shortest-time synchronization of a Loran C signal with a synchronous pulse by detecting another Loran C signal based on time lag data previously memorized using the Loran C signal initially detected as reference. CONSTITUTION:2A represents a Loran C signal, M host station signal and S1 and S2 first and second slave station signals respectively. When the synchronous operation of the master station synchronous pulse PM is ended initially, a microprocessor takes in and memorizes time lags TD1 and TD2 to the slave station synchronous pulses PS1 and PS2 measured with a time lag measuring circuit using the master station synchronous pulse PM and subtracts the time TD1 and TD2 to calculate the time difference TA and TB. The synchronous deviation data TA and TB are sent out to a synchronous pulse generation circuit to shift the phases in the slave station synchronous pulses PS1 and PS2 in the direction of eliminating the synchronous deviation while the first and second slave station synchronous pulses PS1 and PS2 synchronize with specified positions of slave station Loran C signal respectively.
