In a solar cell, at least one of reinforcing material and buffering material is provided at least partially on at least one of a back surface, a front surface and a side surface of the solar cell. With these reinforcing material and/or buffering material, occurrence of cell fracture due to load imposed by external force can be decreased.

The present invention provides a PLL circuit containing a loop gain circuit capable of suppressing loop gain variation. This PLL circuit includes a counter that is driven by a voltage controlled oscillator within the PLL circuit, an accumulator (ACL) that accumulates the output of the counter, and a comparison operation circuit block that compares the count value of the ACL and the design value pre-stored in a register, and the loop gain of the PLL circuit is detected taking advantage of the fact that the ACL count value is inversely proportional to the loop gain. Based on the detection result, the loop gain is calibrated by correcting the loop gain with a charge pump current, etc. This allows the PLL circuit to maintain stable loop characteristics that will not affect the characteristics variation of each element constituting the PLL.

Into an internal circuit to operate in a high-frequency band, there is incorporated a protective circuit of a multistage connection which is constructed to include a plurality of diode-connected transistors having a low parasitic capacity and free from a malfunction even when an input signal higher than the power supply voltage is applied. Into an internal circuit to operate in a low-frequency band, there is incorporated a protective circuit which is constructed to include one diode-connected transistor. The protective circuits include two lines of protective circuit, in which the directions of electric currents are so reversed as to protect the internal circuits against positive/negative static electricities.

A plasma processing method performs a desired plasma process on substrates by using a plasma generated in a processing space. A first and a second electrode are disposed in parallel in a processing vessel that is grounded, the substrate is supported on the second electrode to face the first electrode, the processing vessel is vacuum evacuated, a desired processing gas is supplied into the processing space formed between the first electrode, the second electrode and a sidewall of the processing vessel, and a first radio frequency power is supplied to the second electrode. The first electrode is connected to the processing vessel via an insulator or a space, and is electrically coupled to a ground potential via a capacitance varying unit whose electrostatic capacitance is varied based on a process condition of the plasma process performed on the substrate.

A wireless communication receiver that is able to lessen the effect of noise that accompanies gain change by programmable gain amplifiers. The receiver includes an AGC controller which controls the timing at which the programmable gain amplifiers make gain change, using a terminal counter and a sequencer. The receiver prevents gain change noise signals during the reception of control signals and other signals that are susceptible to noise. By the timing control feature, the programmable gain amplifiers make gain change while reducing noise impact.

[OBJECTS] To provide an elastic strip material that has a cross-sectional shape suited to intended uses such as seals or cushions, as well as a method of and an apparatus for mass-producing the strip material efficiently and inexpensively. [MEANS FOR ACHIEVING THE OBJECTS] A heat setting composition is used whose main ingredients are a polyurethane prepolymer and a latent solidifier obtained by deactivating a solid polyamine. A compressed gas is dispersed throughout the composition to give a fluid mixture ‘a’, that is then foamed and heated to or above a critical temperature to solidify as the strip material. The fluid mixture ‘a’ is extruded from an extruder (1), guided into a liquid or gaseous heating zone (2), caused to solidify during travel within the zone, and shaped at the same time into a desired configuration before discharged from the zone (2).

An image signal processing apparatus includes two JPEG codecs. A plurality of frames of image signals periodically input from a multiplexer are individually compressed by the two JPEG codecs, and the compressed image signals are recorded on a hard disk by an HDD. Furthermore, the plurality of frames of the compressed image signals reproduced from the hard disk are individually expanded by the two JPEG codecs, and the expanded image signals are output to a monitor. Herein, each of the JPEG codecs selectively executes individual compression of the plurality of frames of the image signals and individual expansion of the plurality of frames of the compressed image signals. A CPU makes the JPEG codecs perform the compression process prior to the expansion process.
