Title: Heat treatment for compound semiconductor substrate
Inventor: MURAI SHIGEO
IPC: H01L21/324
Filed: 1984-07-26
Abstract: PURPOSE:To prevent dispersion of the electrical characteristics of a compound semiconductor substrate from generating by a method wherein a dielectric protective film is provided on the surface of the compound semiconductor substrate, the substrate is held between two sheets of substrates of the same kind and a heat treatment is performed in a temperature range ranging from a temperature, at which impurity atoms constituting the substrate and vacant lattices thereof begin to diffuse, to the melting point of the crystal of the substrate. CONSTITUTION:A dielectric protective film 2 is formed on the surface of a GaAs substrate 1 and a heat treatment is performed in a state that the GaAs substrate 1 is being held between two sheets of GaAs substrates 3 and 4 different from the GaAs substrate 1 in its upper and lower sides. This heat treatment is aimed at homogenizing the crystal interior of the GaAs substrate 1 and is performed at 700-1,200 deg.C ranging from a temperature, at which impurity atoms constituting the crystal and vacant lattices thereof begin to diffuse, to the melting point of the crystal. By this way, strain due to a temperature difference, which is applied to the dielectric protective film 2 at the times of temperature rise and temperature drop, becomes less, because the dielectric protective film 2, which coats the front side face and the back side face of the GaAs substrate 1 and is one for suppressing the evaporation of high-vapor pressure parts of the constituent elements of the substrate 1 is tightly adhered with the GaAs substrates 3 and 4 different from the GaAs substrate 1. Accordingly, such a fear as a break of the dielectric protective film is decreased.

Abstract: PURPOSE:To prevent malfunctioning of an oil-level detecting apparatus for an engine, by employing such an arrangement that the polarity of magnets buried in a ring-shaped float of an oil-level detector disposed in an oil sump is made equal to that of an igniting magnet buried in a flywheel at a portion of its outer circumference. CONSTITUTION:In a crankcase which supports a crankshaft 4 having a flywheel 9 fixed to one end thereof in a freely rotatable manner, a detector 14 consisting of a reed switch 13 and a ring-shaped float 11 having magnets 12 buried therein is disposed in an oil sump downwardly of the crankshaft 4. In the above arrangement, the polarity of the magnets 12 at the lower side is made equal to the polarity of a magnet 15 at its outside, which magnet 15 is used for an igniting unit and buried in the flywheel 9 at a portion of its circumference. Since, by employing such an arrangement, the magnetic force of the magnets 12 can be augmented by the magnetic force of the magnet 15 when the magnet 15 is moved to a lower position along with rotation of the flywheel 9, it is enabled to ensure operation of the reed switch 13 by the float 11 that is moved in response to the oil surface.

Title: Character pattern reduction conversion system
Inventor: TANDAI SHINJI
IPC: G09G5/26
Filed: 1990-06-15
Abstract: PURPOSE:To eliminate an error accompanied with the reduction of the character pattern of a full dot by performing the reduction prcessing of the contour line of the character pattern after it is vectorized. CONSTITUTION:Even when lines AB and AC expressing the contour of the character pattern which is developed to the full dot are taken as straight lines and vector-approximation is performed by setting the lines AB and AC as the contour line, the forms of the lines are not changed. When the character pattern which is formed to a vector font is 1/3 reduced next, lines (ab) and (ac) respectively correspond to the lines AB and AC. Namely, since the lines are treated as vector in reduction processing, the contour of the character pattern is not changed even after being reduced. Thus, th character pattern having little deterioration of quality is generated.

Title: Heat exchanging pile and heater
Inventor: UMEMIYA HIROMICHI
IPC: E01C11/26
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To absorb geothermal energy as much as possible by piles having a limited volume by embedding spiral heat-exchanging pipes on which outgoing and incoming pipes in which a heat medium flows are wound alternately, in a concrete hollow pile body. SOLUTION: When a heat medium such as antifreeze liquid is poured from one side of a water passage way 4 into heat-exchanging pipes 2 of a heat exchanging pile A embedded in the ground, the heat medium is heated as it absorbs the geothermal energy while passing through outgoing and incoming pipes 5b, 5c in a spiral part 3. The heated medium circulates the inside of meandering radiation pipes of a radiation block through flow rate adjusting valves and flow rate meters by a circulation pump for instance. After the medium has heated the radiation block, it returns back to the circulation pump through the respective flow rate adjusting valves and flow rate meters.  In this way, extremely long heat-exchanging pipes compared with the length of the pile can be provided and hence, the heat-absorbing area can be increased and the heat-absorbing efficiency of the geothermal energy can be improved.
