Title: Information processing unit employing expensive power supply
Inventor: KITAGUCHI TERUYUKI
IPC: G06F1/04
Filed: 1995-06-05
Abstract: PURPOSE: To extend the battery service life by selecting a frequency of a clock signal depending whether an input coordinate is resident in a pen entry operation area requiring high speed processing or in an entry operation area without any hindrance even at low speed processing. CONSTITUTION: Plural frequency clock generating means 1, 2 generate a clock signal with plural frequencies as a clock signal synchronously with or acting like a reference signal of a central processing unit 6 or the like. An entry means 3 accepts entry including hand-writing entry. An input coordinate position detection means 4 detects an input coordinate in the XY coordinate system to the entry means 3. An input coordinate discrimination means 8 references the input coordinate detection means 4 to discriminate whether or not the input coordinate is within a prescribed area preset by the entry means 3. A clock frequency changeover means 7 switches higher frequency of the clock signal generated by the plural frequency clock generating means 1, 2 by a prescribed procedure when the input coordinate discrimination means 8 discriminates that the input coordinate is resident in an area determined to be a hand-writing entry area requiring high speed processing.

Abstract: PURPOSE:To attain focus control with high accuracy by providing a focus detection system and an automatic zero amplifier and a detection system changeover switch. CONSTITUTION:The focus detection system 28, the automatic zero amplifier 29 and a detection system changeover switch 30 are provided. The focus detection system 28 detects a focus error of a light beam of an Ar laser 1 by the astigmatism method. That is, the light the Ar laser 1 separated from a polarized beam splitter 15 is received by a four division photodiode 31 and its output signal is converted into a voltage by a photoelectric conversion circuit and the focus error of the Ar laser light is detected from the output signal of the photoelectric conversion circuit 32. Further, the automatic zero amplifier 29 amplifies an output signal of the focus detection system 17 so that the output signal is zero when the output signal of the focus detection system 28 is zero nearly the same as the output signal of a focus detection system 28. The switch 30 is thrown to the position of the focus detection system 28 at focus servo pull-in and the focus error signal from the focus detection system 28 is inputted to a control system 22 via the switch 30.

Title: Liquid fuel combustion apparatus
Inventor: KAMIYA SHIGERU
IPC: F01N3/025
Filed: 1980-10-03
Abstract: PURPOSE: To reduce the amount of discharge of unburned hydrocarbon at the time of ignition and extinction of fire through a comparatively small-sized device by a method wherein a fuel is vaporized after it is mixed with heated combustion air.  
     CONSTITUTION: Air supplied from a combustion air supply device comprising a pump or the like flows into the liquid fuel combustion apparatus from an air inlet of the latter. Then, the air passes through an electrical heater block 2 to be heated up to a temperature between about 200 and 300°C and flows into a mixing chamber 4 via a communication hole 3. On the other hand the fuel supplied from a liquid fuel supply device flows into the combustion apparatus through a pipe 5 and is injected into the mixing chamber 4 through a nozzle 5a. As a result, the fuel is subjected to a high speed stream of the heated combustion air so that the amount of discharge of the unburned hydrocarbon at the time of ignition and extinction of fire can be reduced.

Title: Printing method employing electrically conductive rubber platen
Inventor: NAKANO ICHIZOU
IPC: B41J11/02
Filed: 1978-11-10
Abstract: PURPOSE: To make possible a clear printing with a limited impact through elevation of the temperature of a color developing substance in the pressure-sensitive copying paper by means of a electrically conductive rubber used on the circumference of a rubber platen in the impact printer while lowering the ink viscosity by the current applied.  
     CONSTITUTION: The circumferential rubber section 10 of a rubber platen 1 in the impact printer is made up of an electrically conductive rubber. Current flows through the electrically conductive platen 1 to generate heat whereby the printing paper 2 wound on the platen 1 is heated up to the required temperature. Then, a given type element 4 is selected with a type selection drive motor 6 and is made to impact on the electrically conductive rubber platen 1 by means of a hammer through the printing paper 2 and an ink ribbon 3. Thus, a printing is performed. If the printing paper is a carbon paper, a solid ink is melted thereon. In addition, since a printing is made under the lower ink viscosity with the ink ribbon pressed against the heated rubber platen 1 or the printing paper, sufficient printing density can be obtained even with less impact energy of the hammer 5.

Abstract: PROBLEM TO BE SOLVED: To produce activated alumina of high quality catalyst by recrystalizing a double salt from a solution of potassium aluminum sulfate under a heated and pressurized condition, precipitating out a purified basic double salt, drying, and sintering it to form alumina containing potassium sulfate, and removing the potassium sulfate by washing with water. SOLUTION: A potassium aluminum sulfate as a feeding raw material is dissolved into a pure water to form a solution and heated to about 85 deg.C. Then the solution is vaporized at about 65 deg.C for recrystalizing a double salt to obtain a purified basic double salt and impurities are removed by precipitating from the solution. The crystal of the double salt is kept at about 95 deg.C and, after adding a hot water, a basic double salt is precipitated at about 200 deg.C and 250 psi. After this precipitated double salt is dried, the sulfate is removed by sintering at about 850-950 deg.C and potassium sulfate is removed by washing. Then the residual alumina is dehydrated and an activated alumina is obtained.
