IPC: F24H1/00
Filed: 1982-06-23
Abstract: PURPOSE:To generate frictional heat and other heat under a pressure-reduced equilibrium state in the so-called ventilated condition, by reducing the air rate sucked from the outside of a hollow chamber, in comparison with the air rate discharged from the hollow chamber by a rotator. CONSTITUTION:The air sucked into a hollow chamber 2 from an open-air suction part 6 is forcibly sucked by a rotating rotator 4 provided in the hollow chamber 2, and is discharged from the chamber 2 through an inner air discharger part 5, after circulating through the chamber 2. At the same time, the difference in pressure inside and outside of the chamber 2 is kept in about a constant equilibrium state. With the equilibrium state being kept, the frictional action with the air is promoted by the rotator 4 continuously rotating to generate the frictional heat 3. The hollow chamber 2 is heated by the frictional heat, and the heating energy in the air discharged from the chamber 2 is heat- exchanged with the sucked air by a heat exchanging mechanism 7 consisting of the inner air discharger part 5 in which the open-air suction part 6 is unitarily incorporated.

Title: D-a converter
Inventor: IDA SHIZUO
IPC: H03M1/74
Filed: 1986-05-09
Abstract: PURPOSE:To attain the normal operation regardless of the quantity of an input voltage by connecting a resistor and a diode to an input terminal of a D-A converter. CONSTITUTION:The clamp voltage is adjusted by number of diodes 24-29 so that transistors (TRs) 2-6 are not saturated by the combination between voltages at terminals 21-23 and clamp voltages of diodes 24-29.

Title: Dubbing device for video signal
Inventor: KOBAYASHI TOSHIHARU
IPC: G11B5/86
Filed: 1981-07-09
Abstract: PURPOSE:To prevent malfunction which is not detected as a dropout during the reproduction of a slave tape by detecting a dropout during video signal dubbing and then recording the dropout even on the slave VTR. CONSTITUTION:If a modulated luminance signal YFM outputted from an HPF10 contains a dropout, a dropout detecting circuit 14 generates a detection pluse Pd. A limit switch 13, on the other hand, outputs a modulated luminance signal (YFM)' which is muted during the dropout period as shown in Fig. D to a terminal 1a because a switch circuit 15 grounds the signal line in terms of high frequency by the detection signal Pd which becomes a noise during the dropout period, and the generated signal is stored in a buffer circuit 16. Through this circuit 16, record is dubbled from a master VTR to a slave VTR and the dropout is also recorded accurately on a slave tape, thereby preventing malfunction which is not detected as a dropout during the reproduction of the slave tape.
