摘要： A precursor film having a required gallium component proportion is formed easily at low cost. A precursor film for use in forming the light absorption layer of a CIS type thin-film solar cell, etc., or a method for forming the film are provided. A Cu—Ga layer having a high gallium component proportion (Ga/(Ga+Cu)) of X % by weight Ga is formed as a first layer by sputtering using a precursor film comprising a Cu—Ga alloy layer having the gallium component proportion of X % by weight Ga as a target (deposition step A). Thereafter, a copper layer is formed as a second layer on the first layer by sputtering using a copper layer as a target (deposition step B) to thereby form a precursor film having the required gallium component proportion of Y % (X>Y) by weight Ga as the sum of the first layer and second layer. A method of film formation by simultaneous vapor deposition is also possible.

摘要： This invention provides a CIS-based thin film solar battery and a process for producing the same in which the formation of an alkali barrier layer and a metal backside electrode layer is carried out at a low cost in a short time to prevent such an unfavorable phenomenon that a light absorbing layer is separated from the interface of the light absorbing layer and the metal backside electrode layer. The CIS-based thin film solar battery (1) comprises a glass substrate (2), an alkali-free layer (7) such as silica, a metal backside electrode layer (3) having a laminate structure, a p-type CIS-based light absorbing layer (4), a high-resistance buffer layer (5), and an n-type window layer (6) stacked in that order. The layer (7), either alone or together with a first layer (3a) in the layer (3), can function as an alkali barrier layer (8) that can prevent and control the thermal diffusion of an alkali component into the light absorbing layer during the formation of the layer (4) from the substrate (2). In the layer (3a), crystal grains are fine and has high density. After the formation of the layer (7) on the substrate by RF or DC sputtering, the layer (3) is continuously formed on the layer (7) by DC sputtering.

摘要： In an output-controlled power amplifier of a closed loop type, an input signal is inputted to a main path in which the input signal is power-attenuated by a variable attenuator and power-amplified by a power amplifier. A power divider distributes the amplified input signal between the main path and a feedback path diverging from the main path so that the signal distributed to the main path is outputted from the main path to the exterior while the input signal is controlled on the basis of the signal distributed to the feedback path. The feedback path includes a hold circuit for extracting the signal distributed to the feedback path and holding the value of the power of the extracted signal when the power reaches a predetermined value. A control signal for attenuating the power of the input signal inputted to the main path is generated by the hold circuit and is applied through the feedback path to the variable attenuator on the main path to control the power of the input signal. A transfer function of the closed loop has a Gaussian characteristic.

The waveform converter converts the voltage waveform on a time axis of a rectangular wave output by the charge-pump circuit into a waveform which: is symmetrical with respect to a predetermined point of time; oscillates so as to have no direct-current component; and has a maximum value of the absolute values of maximums of wave heights thereof located at the center wherein the absolute value decreases uniformly as the wave height is separated farther away from the center. As a result, the amplitudes of a limited number of emission line spectra forming a spurious signal superposed on a signal propagating around the PLL can be made uniform and a maximum thereof can be held at a low value, allowing the direct-current component to be eliminated from the signal propagating around the PLL.
