Title: Manufacture of thin-film solar battery
Inventor: URABE KYOICHI
IPC: H01L31/04
Filed: 1992-07-07
Abstract: PURPOSE:To improve a conversion efficiency by decreasing a recombination center through removing an impurity such as CuSe2 existing in the vicinity of a CuInSe2 surface and also by removing the uncombined hand of Cu and In. CONSTITUTION:After Mo electrode layer 2 is formed, Cu thin-film layer and In thin-film layer are formed continuously and a CuInSe2 thin-film layer 3 is formed by selenide formation method. Subsequently, an impurity such as CuSe2 in the vicinity of the surface of the CuInSe2 thin-film layer is removed by etching through the immersion in ammonium polysulfide solution or ammonium sulfide solution so that a film mainly composed of S is formed on the surface of the thin-film layer. Thus, a recombination center decreases and the conversion efficiency of a solar battery improves. Also, this method has the effect of simplifying a manufacturing process and reducing a cost.

Title: Automatic resolution selection facsimile equipment
Inventor: YOKOYAMA TAKASHI
IPC: G06T7/00
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent small characters from becoming illegible by calculating the number of pixels and the ratio of black pixels, with which a white section between black sections of an original image disappears, and automatically selecting suitable resolution corresponding to the result. SOLUTION: An original is inputted from an input part 10, read and reduced by a reduction part 18. A white/black pixel counting part 20 calculates the number of pixels and the ratio of black pixels with which a white section between black sections of a reduced original image disappears. Corresponding to this calculated result, a resolution setting part 22 determines the most appropriate resolution for reading characters and transmits it through a transmission part 16. Namely, it is determined whether the count/black pixel of the count part 20 is larger than a constant (a) or not and when the count/black pixel is larger than the constant (a), facsimile transmission is performed while keeping high resolution. When the count/black pixel is smaller than the constant (a), on the other hand, facsimile transmission is performed after reduction.  Thus, even when there is an area printed out in black, it can be transmitted with a suitable resolution.

Abstract: PURPOSE:To control the inclination of a Bragg surface over the entire surface of a hologram when the hologram is duplicated as to a method and device for hologram duplication which expose a copy dry plate by irradiating a master hologram with laser light. CONSTITUTION:A rotary mirror part 10 rotates under the command of a rotary mirror control part 20 and a mirror 12 rotates and moves to, for example, positions 12A and 12B. Consequently, the laser light 5 is reflected by mirrors 12, 12A, and 12B to scan the master hologram with copy light beams 50, 50A, and 50B. The interference fringes of the master hologram are copied onto the copy dry plate by exposure to the scanning copy light 50. At this time, a scanning fulcrum 13 on the mirror 12 also shifts in position. Namely, when the mirror 12 rotates and moves toward the 12B, the position of the scanning fulcrum 13 also moves to 13B.

Patent JP-S5881326-A (JP)
Title: Frequency to voltage converter
Inventor: BANDOU AKINORI
IPC: H03K9/06
Filed: 1981-11-10
Abstract: PURPOSE:To eliminate the influence of fluctuation of a power supply voltage, by integrating the output of a phase comparator which inputs an input signal at its negative input terminal, resetting an RS.F-F and discharging the integrating circuit when the output of the comparator rises to a high potential while setting the F-F and feeding the frequency division result of the output of the RS.F-F back to the other input of the phase comparator. CONSTITUTION:When an input fi rises to a level H while the output f0 of a frequency divider 17 is at a level L, the output of a comparator 18 goes up to the level H to charge a capacitor 12. Once the charging potential reaches V2, an F-F16 is reset and while the output of the frequency divider 17 is held at the level H, the output of the comparator 18 is held at the level L to discharge the capacitor 12. As the potential of the capacitor 12 drops to V1, the F-F is set again until the input fi goes down to the level L, and then restarts operating once the input fi goes down to the level L. An input of frequency twice as high as the input frequency is supplied to a smoothing circuit, so ripples are less and when variation of a power source occurs, the output pulse width of the comparator 18 varies to compensate the fluctuation of power supply voltage.

Title: Automatic level control circuit
Inventor: MAEHARA YOSHIHIRO
IPC: H04B1/04
Filed: 1990-07-06
Abstract: PURPOSE:To facilitate an adjustment control by controlling an upper limit limiting the voltage level of a transmission signal and a gain with respect to the transmission signal interlockingly with each other. CONSTITUTION:Since the absolute level of a gain control voltage Vout is changed by varying a reference voltage Vref, the upper limit of a transmission signal to obtain the operating point of a limiter circuit 18 is changed as L1 L2 L3. Simultaneously, since the voltage level of the operating point when the diode D1 of the limiter circuit 18 is turned on/off attended with the change in the reference voltage Vref is also changed, the gain of an ALC amplifier 10 is changed as G1 G2  G3. Thus, when the reference voltage Vref is adjusted, since the upper limits L1-L3 of the voltage level with respect to the transmission signal and the gains G1-G3 are controlled interlockingly with each other, the adjustment of them is facilitated.
