IPC: F24F6/12
Filed: 1984-07-31
Abstract: PURPOSE:To provide a ultra-sonic humidifier that is capable of detecting the humidity with a greater accuracy and displaying the temperature by correcting the fluctuation of the output due to the temperature change of a humidity sensor by a temperature sensor. CONSTITUTION:When a humidity/temperature display circuit 39 is selected to the humidity display, a selector switch 31 is connected to (b) contact point, and is connected to the output terminal of an amplifier 25. That is, the output of a humidity sensor 21, after being amplified, is corrected in regard to the temperature by being divided by a resistor 25 and a temperature sensor 33 that has a variable resistance level depending on the temperature, and the corrected voltage is inputted to the plus side input terminal of an amplifier 51 of the display circuit 39. LED's 9a,9b... are illuminated by the emitter voltage of a transistor 56 that changes in accordance with the output of the amplifier 51. When the temperature display is selected, the selector switch 31 is connected to the (c) contact point to cause the resistor 32 and resistor 37 to be connected, and the divided component voltage is inputted to the amplifier 51. Then, the output determined by the detected temperature by the temperature sensor 33 cause the LED's 9a,9b... to be illuminated.

Title: Bearing device of internal combustion engine
Inventor: NARA TAMOTSU
IPC: F16C33/12
Filed: 1981-10-12
Abstract: PURPOSE: To obtain a bearing device of an internal combustion engine with superior fatigue, wear and seizing resistances by using spheroidal graphite cast iron as a shaft material and a Cr rich Al-Sn alloy as a bearing material.  
     CONSTITUTION: An alloy consisting of, by wt., 3.5W35% Sn, >1.0W7.0% Cr and the balance essentially Al is used as a bearing material. In order to manufacture bearings using this alloy, the alloy is press-welded to a backing steel strip and annealed several times to increase the bonding strength. At this time, precipitated Al-Cr intermetallic compound prevents the migration of Al grain boundaries and inhibits the growth of Al grains, so Sn grains are not made coarse by the annealing. Since this fact is applicable to the case where the alloy is set at a high temp. comparable to that of the annealing, the fatigue strength is enhanced by preventing softening. The resulting bearing device has high seizing surface pressure, superior fittability and seizing resistance, and it brings a smooth friction torque change.

Abstract: PURPOSE:To form an isorated region in such a form determined by the shape of recessed part, accurately form the recessed part of miniaturized area without generating a bird beak and realize high integration density by electrically depositing a glass substance on the recessed part with a suspension including glass substance powder and conductive additive. CONSTITUTION:The suspension, which is obtained by mixing low melting point glass powder to methyl alcohol, for instance and also adding a small amount of aqueous solution of AlCl3 in order to give conductivity for electrical deposition, is put into a vessel 17. After disposing in parallel an electrode 19 holding a semiconductor substrate 11 as a cathode and a platinum plate 20 as an anode, these electrode plates are connected to an external DC power supply 21. After the semiconductor substrate 11 and the anode plate 20 are perfectly immersed in the suspension 18, a voltage is applied thereto. Thereby, the glass powder is adhered to only the area on the semiconductor substrate 11 where an oxide film is not formed. Since the oxide film is not formed only at the recessed part 14, the glass is adhered only to the recessed part 14. Thereafter, the substrate is subjected to heat treatment at a temperature determined by the property of low melting point glass. Thereby, the glass powder becomes perfect insulating film, filling the recessed part 14.

IPC: H01L23/06
Filed: 1982-09-17
Abstract: PURPOSE:To measure a temperature rise of the encasing vessel on inspection or after mounting easily by setting up a heat-electricity converting element approximately just under a region on which a semiconductor element is placed. CONSTITUTION:The heat-electricity converting element is set up approximately just under the semiconductor-element placing section of the encasing vessel. For example, structure in which a thermocouple is incorporated in a ceramic-package 1 is formed, the thermocouple is formed by a metal A7 and a metal B8 at that time, and a temperature change of potential difference due to the contact of the metals of a different kind of A and B can be detected through leads 4, 4'. The metals 7, 8 are printed and formed previously before the package is manufactured. Accordingly, since the thermocouple for measuring the temperature rise or a resistor is unified with the encasing vessel, a temperature can be measured easily on inspection, and heat can be controlled easily.

Title: Method of separating pigment from pigment phosphor
Inventor: FURUKAWA YASUNORI
IPC: C09K11/01
Filed: 1985-07-23
Abstract: PURPOSE:To completely remove a pigment from the surface of the matrix of a phosphor, by placing a pigment phosphor in an alkaline soln., heating and stirring the soln. to allow the pigment to peel from the phosphor, quenching the soln. and removing the supernatant on which the separated pigment is suspended. CONSTITUTION:A pigment phosphor prepd. by bonding a pigment to the surface of the matrix of a phosphor is placed in an alkaline soln. The soln. is heated and stirred to allow the pigment to peel from the phosphor and quenched. The supernatant on which the separated pigment is suspended is removed, thereby separating the matrix of the phosphor. The adoption of the quenching step in the present method brings about the solidification or semi-solidification of the binder which is in a dissolved or softened state in an alkaline soln., which deteriorates or loses the function of the binder. This prevent the pigment from rebonding. The complete removal of the pigment enables efficient reuse of the matrix of the phosphor.
