Title: Electric foot warmer sunk below floor
Inventor: MATSUDA ISAO
IPC: F24C15/22
Filed: 1986-10-13
Abstract: PURPOSE:To emit radiation heat almost uniformly onto the whole circumference efficiently with a simple construction by enclosing the circumference of a heat generating body installed laterally at the central section of an electric foot warmer sunk below floor with a heat reflector which consists of the honeycomb body of semicircular metal foil. CONSTITUTION:When an electric current passes through a heat generating body 3, the radiation heat emitted from the heat generating body 3 is spreaded on the upper side section of the whole circumference of a main body. Here the reflection of the radiation heat has the property of collecting and the radiation heat is spreaded uniformly in the electric foot warmer sunk below floor smoothly, because hexagonal pillars covered by aluminum foil as a high reflection material are gathered in a honeycomb work to form a reflection body 2 around the hole of the main body of the electric foot warmer sunk below the floor around the heat generating body 3. Further, the reflection light that is reflected and refracted on the wall face is reflected on the whole face of the reflection body 2 to increase pleasant visual effects. As a result it is possible to emit radiation heat efficiently and uniformly in the electric foot warmer sunk below the floor with the simple construction of a heat generating body 3 and a reflection body 2.

Then, heat annealing is carried out on the amorphous silicon film, thus dehydrogenating the film. Thus, a native oxide 4 is formed on a polycrystal silicon film surface 31. Then, the natural oxide film 4 on the surface is removed by etching in a dry etching chamber, and the substrate on which etching is completed in a vacuum is transported into a laser annealing chamber, via a transfer chamber maintained in a vacuum. The amorphous silicon surface 31 is irradiated with a laser beam, thus forming a polycrystal silicon film 32 on the entire surface of the substrate.

Abstract: PURPOSE:To completely perform the pulse removal generated for the vertical synchronizing signal period by providing a means to output a signal to enlarge the width of the low level of a horizontal synchronizing signal. CONSTITUTION:The composite synchronizing signal of a waveform IN inputted from an IN terminal is directly inputted to a terminal A1 of an AND gate 5, and to a terminal A2, the waveform in which the composite synchronizing signal is integrated by a resistance l and a capacitor 2 is inputted. For this reason, for the waveform inputted to the terminal A2, during the vertical synchronizing signal period, the voltage is low, the voltage of the terminal A2 is low, the AND gate 5 is closed, and to a terminal A3, most of the cutting pulse of the vertical synchronizing signal period is erased and the waveform is outputted. By passing the waveform through a one-shot-multivibrator 6, as shown by a waveform OUT, the pulse in which a constant period TD decided by a resistance 3 and a capacitor 4 becomes a low level is obtained. At this time, when the period TD is set longer than a period TS Of the waveform IN, the cutting pulse of the vertical synchronizing signal period is removed.

The head is then heated up to the temp. at which the paste melts in a non-oxidative atmosphere of gaseous H2, gaseous mixture composed of N2-N2 or the like or in a vacuum. The magnetic head is held for several minutes at said temp. to bring the Al2O3 and the alloy into reaction with each other and to form an intermediate layer 6 consisting of TiO3, ZrO2, etc. The upper layer is thus formed of the alloy layer 5'. The head is then cooled down to a room temp. and a laser beam 7 is irradiated to the metallic flexure 2 consisting of SUS, etc. to melt the alloy 5', thereby forming a united alloy phase 8. The magnetic head is thus assembled in the short period with the good accuracy.
