Title: Rotary head type magnetic video recording and reproducing device
Inventor: TANIGUCHI HIROSHI
IPC: G11B15/467
Filed: 1982-03-08
Abstract: PURPOSE:To discriminate stably a recording mode, by recording a pilot signal for discrimination of the recording mode. CONSTITUTION:The video signal supplied from an input terminal 1 is separated into a luminance signal and a modulated color signal by an LPF2 and a BPF4. The luminance signal undergoes the FM modulation through an FM modulating circuit 3; while the modulated color signal is added through an adder 6 after conversion of the low band through a circuit 5. On the other hand, the signal of a pilot signal generator 8 is gated by a gate circuit 9 for a certain period of a vertical blanking time and then added with the modulated video signal by an adder 7. The output of the adder 7 is recorded on a magnetic tape by rotary heads 13 and 13' and via a recording amplifier 10, a record/reproduction changeover switch 11 and a slip ring 12. In a reproduction mode the presence or absence of the pilot signal is detected by a detecting circuit 27, and the recording mode is automatically detected.

Title: Combustion apparatus
Inventor: ITO TERUAKI
IPC: F24H3/06
Filed: 1990-02-16
Abstract: PURPOSE:To eliminate disadvantages such as odor and indoor air pollution by providing an exhaust top or a suction and exhaust top with an exhaust fan for sucking in an exhaust gas generated by combustion in a combustion chamber and exhausting the exhaust gas outdoors. CONSTITUTION:The air for combustion is taken in from a suction and exhaust top 3 by the suction of an exhaust fan 9. A fuel separately supplied to a combustion section 2 via an intake hose 4 is burnt in a combustion chamber 6. A generated exhaust gas radiates heat in a heat exchanger 7 and exhausted outdoors from the suction and exhaust top 3 via an exhaust pipe 8 by the exhaust fan 9. When a very slight airtightness failure is generated in an exhaust gas path in a combustion state, the exhaust gas is exhausted from a suction and exhaust top 3 together with the indoor air while being sucked a little through a part wherein the airtightness failure is generated. Thus, even when there is any insufficiently airtight part, there is no fear of the leakage of the exhaust gas in a room and a combustion apparatus can be safely used.
