Patent JP-S5654228-A (JP)
Title: Production of low-na2o sintered-alumina
Inventor: SUMI MOCHIYUKI
IPC: C01F7/46
Filed: 1979-10-09
Abstract: PURPOSE: To reduce the content of NaO 2  in sintered alumina by a method wherein a part of the furnace gas is extracted from the area at which the temperature is at the maximum in the shaft kiln, to the outside of the shaft kiln, so that the gas would not contact the charged alumina and thereby preventing Na 2 O from circulating in the furnace.  
     CONSTITUTION: Formed grains 3 of Bayer alumina are dropped from the top of the cylindrical, vertical type furnace of a shaft kiln, and are sintered by high-temperature combustion gas which is blown through the gas-blow hole 2a at the center area. At this time, a part of the gas is discharged to the outside of the kiln, by means of the peripheral-degasing mechanism 5 having plural vertical holes 5a which extend along the inner wall of the furnace 2. The amount of discharged gas is controlled by the gas-extraction regulator 6 installed at the top of the vertical hole 5a. This prevents the circulation of Na 2 O in the furnace 2 and provides a sintered alumina whose Na 2 O content is less than about 0.25%.

With such resist film 6 used as the mask, the periphery of layer 2 is removed with the width of 2um by the etching. Thereafter, elements such as transistor are formed within the remaining layer 2. Here, the periphery is removed by the etching but it may be removed after it is changed in nature by oxidation by the selective oxidation method. As described above, the periphery wherein fine crystal particles are still remaining is perfectly removed.

Title: Ink particle forming device
Inventor: YAMADA TAKEHIRO
IPC: B41J2/02
Filed: 1981-08-21
Abstract: PURPOSE:To make it possible to carry out stable and good recording by stabilizing the formed conditions of ink particles even if the temperature or density of ink varies by partially narrowing down the internal crosssection of a nozzle pipe on the midway. CONSTITUTION:To the top end of a nozzle pipe 11 which is substantially phi1 in internal diameter, but of which intermediate portion is narrowed down to phi2 in internal diameter, an orifice plate 13 having a nozzle hole 12 is installed and a piezo-electric vibrator 14 is installed around the pipe. A voltage from a high frequency power source 15 is impressed to the piezo-electric vibrator 14. As the excitation frequency F of an ink particle forming device is set in the vicinity of 3/4.C/L, the variation of impedance in the vicinity of this frequency or a frequency 2F is gentle and less. Because of this mechanism, even if the temperature or density of ink varies and the supersonic speed of ink is resultantly changed, acoustic impedance in the vicinity of the exciting frequency F or 2F does not show remarkable change.

Filed: 1980-09-18
Abstract: PURPOSE:To manufacture a non-liquid leakage cell arranging a positive electrode holding gel electrolyte in a cell case together with a negative electrode, then supplying electrolyte containing polymer and gelling the electrolyte before or after sealing the cell. CONSTITUTION:A positive electrode is impregnated with organic electrolyte, for example, gamma-butyrolactone dissolving 1mol/l of lithium borofluoride containing polymethacrylic alkyl ester, namely a sort of polymer gelling agent, which shall be then heated in order to gel the impregnated electrolyte for making the positive electrode 5. Then a cell is formed with the positive electrode 5 together with a separator 7 and a negative electrode 4, then the electrolyte containing said gelling agent is supplied into the cell and the cell is heated before or after sealing it in order to gel the supplied electrolyte. In this case it is suitable to have the positive electrode impregnated with the solvent of the electrolyte of low viscosity. Thereby, it is possible to manufacture the organic electrolyte cell which is handy, non-water absorptive and has superior discharge character and creep resistance since gelling is conducted by having positive electrode thoroughly permeated by the electrolyte.

Abstract: PURPOSE: To make an optical reader convenient to be used for read of information encoded with wide-range densities to improve the efficiency by making the diameter of diffused light at the point, where diffused light is brought into contact with optical encoded information, different between two different distances. CONSTITUTION: When a spacer 21 is attached relatively far ahead of the front end part of a housing 11 and the front end part of the spacer 21 is brought into contact with a surface S, the distance between a focus P and the surface S is relatively long, and the spot of light is large.

Meanwhile, when the spacer 21 is shortened in the opposite direction on the housing and the front end part or the spacer 21 is brought into contact with the surface S, the distance between the focus P and the surface S is relatively short, and the spot of light is small. This case is suitable for read of information encoded with a high density like a small-sized bar code.

Abstract: PROBLEM TO BE SOLVED: To stabilize an oscillation frequency, by fixing equivalent reflactivities of a front and a rear distribution reflector region to the same value and laser oscillation wavelengths to one wavelength, so that Bragg wavelengths of the front and the rear distribution reflectors may coincide. SOLUTION: Bias current sources 18-21 are connected to a front side distribution reflector region(DBR) 2, a rear side DBR 3, a phase adjusting region 4, and a gain region of an SSG-DBR laser (laser) 1, respectively. The DBRs 2 and 3 are added with sine wave signals from signal sources 16, 17. The output light from the laser 1 is branched by means of fiber couplers 7, 8 and part of the light is guided to a synchronous detector 23 through an optical detector 9. The synchronous detector 23 makes a phase synchronous detection using the signal sources 16, 17, and detects an error A between a reflection peak wavelength and a longitudinal mode wavelength of the front side DBR and an error B between a reflection peak wavelength and a longitudinal mode wavelength of the rear side DBR.  The detected errors A and B are fed back to the DBRs 2 and 3 through an amplifier 14 and a low pass filter 15 to stabilize the laser oscillation frequency.

Abstract: PROBLEM TO BE SOLVED: To avoid a wrong recording efficiency of input information by recording other information that has been received and reached a recording available state earlier in the case that information is on the way of entry and cannot be recorded. SOLUTION: In the case that, e.g. a communication means 4 is on the way of reception of facsimile data and a recording means 8 is not in operation and that print data have already been in an image memory 6, the print data are printed out by a recording means 8 in precedence over the facsimile data on the way of reception.
