Title: Evaporator for liquid fuel
Inventor: OOHASHI YOSHIAKI
IPC: F23D5/06
Filed: 1982-09-27
Abstract: PURPOSE:To momentarily stop evaporation of the fuel and to prevent production of malodor and tar content, by widening a gap between an evaporating body and a film-forming body during fire extinguishing. CONSTITUTION:During fire extinguishing, when turning of a forming body 5, the supply of fuel 3 and energization of a heater are brought to a stop, electromagnets 12, 12..., simultaneously, are energized to attract an evaporating body 2 to the electromagnet 12 side to form a gap H. This causes momentary disappearance of a film and prevents production of evaporated gas, resulting in momentary fire extinguishing. Although slight kerosene remains in a groove in the forming body 5, since the forming body 5 has a low thermal capacity and is separated away from the evaporating body 2, evaporation due to thermal inertia is prevented from continuance. Unlike a previous device, this prevents production of backfire due to evaporated gas generated by the thermal inertia of the evaporating body 2, and production of malodor and tar content.

Title: Optical disk device
Inventor: GOMI AKIHIRO
IPC: G11B21/10
Filed: 1987-07-07
Abstract: PURPOSE:To surely execute pull-in operation by suitably receiving a track address from a track address demodulation part, comparing it with a track address received last time and detecting the moving direction of an optical head. CONSTITUTION:An RF signal including an information signal is also received simultaneously with a track error signal by the optical head 2. The RF signal is outputted to an address demodulation circuit 11 and a PLL circuit 12 after being processed by an RF signal reproduction circuit 10 and synchronized with a clock signal. Then a clock used for the demodulation of the track address, a sector address and recording data is generated. By the address demodulation circuit 11, an address signal is fetched and demodulated. A CPU receives the track address (a) of the last time and track address (b) of this time and immediately obtains (b-a). When the speed of a VCM is slowed down and inverted soon after, the positive and the negative code of the (b-a) is inverted but before and after it, the speed is nearly zero. Therefore when positional control pull-in is executed at the inverting time of the speed or immediately after the inversion, the correct pull-in can be easily executed.
