To provide a signal generator, a signal generating system, and a signal generating method capable of repeatedly generating an arbitrary waveform and making the phases of the head and tail of the generated waveform continuous with each other, without changing the frequency of the waveform. A signal generator (10, 11, 12) includes phase shift means (30) that receives waveform data which is repeatedly output n times, shifts the phase of each sample data item in an n-th waveform data item by a phase shift amount φn corresponding to the number of times n the waveform data is repeatedly output, and outputs the waveform data to D/A conversion means.

The system is a self-oxidation internal heating steam reforming system for conducting self-oxidation of a raw material gas under the presence of oxygen and conducting steam reforming to generate a hydrogen-rich reformed gas. The system includes a steam generator including a combustion section for combusting an air-fuel mixture obtained by mixing a combustion air with a fuel, thereby heating water using a combustion gas generated in the combustion section to generate hydrogen; a first sucking-mixer for sucking the raw material gas into a steam stream coming from the steam generator to obtain a raw material-steam mixture; and a reformer for oxidizing the raw material gas in the raw material-steam mixture by an oxygen-containing gas supplied from outside, thereby conducting steam reforming of the raw material gas using the reaction heat of the oxidation to generate a hydrogen-rich reformed gas.

A light receiving apparatus includes a holder made of metal and a light receiving element that is attached to the holder, receives laser light reflected by an information medium, and outputs an electric signal. The light receiving element is constructed of a bare chip, is attached to the holder, and parts of the light receiving element aside from a part on which the laser light is incident are sealed using resin.

There are provided a light-receiving element for receiving light reflected from an optical recording medium, an optical head using the element, and an optical recording/reproducing apparatus using the element. In particular, the light-receiving element can be manufactured at low cost and in a simple manner and is configured to receive light from a short-wavelength laser source (having a wavelength of 402 nm to 413 nm). The light-receiving element includes a silicon substrate in which a light-receiving portion is formed; a circuit board for mounting the silicon substrate; at least one or more wires for electrically connecting the silicon substrate and the circuit board; a cover layer for covering the wires; and an exposed portion for exposing the light-receiving portion outside.

A sun-roof apparatus for a vehicle which comprises a sun-roof frame forming a gutter having at least two side portions and at least one raised rear portion at a higher height than the side portions, and interposed between the side portions. The gutter is provided under a roof outer plate having an opening opened and closed by a sun-roof panel. The gutter extends along at least three peripheral edges of the opening. An interior plate is arranged under the raised rear portion of the gutter. The interior plate is raised higher than the two side portions of the gutter and capable of moving between a closed position opposed to the opening and unopened position moved backward to a rear of the opening. A drain conduit is connected to each of the two side portions of the gutter. A connecting passage is arranged under the interior plate, wherein ends of the two side portions of the gutter which are close to one of the raised side portions are connected by a recessed groove. The recessed groove is provided in the sun-roof frame in the manner continuous with the gutter side portions and at a position below one of the raised rear portions of the gutter. The recessed groove contains a rear box of an opening and closing unit for controlling opening and closing of the sun-roof panel, and a pair of bank plates are provided between the groove and the side portions of the gutter formed in the sun-roof frame. Each bank plate has an opening therein and a connecting passage which is connected to each bank plate at the opening and arranged beneath the interior plate and within the groove.

An audio signal encoding device includes: a window determination unit for determining the type of window of each channel; a correction unit for correcting the number of available bits; and a quantization unit for quantizing the audio signal of each channel sequentially so that the number of bits is equal to or less than the corrected number of available bits while adding the number of bits left unused, and the correction unit includes: a use rate history calculation unit for calculating a bit use rate in quantization of each type of window; and a corrected bit number calculation unit for correcting the number of available bits so that the rate of used bits to the number of available bits of each channel on the assumption that quantization is performed with the calculated bit use rate in quantization approaches the same.

In a PTC heater unit configured to heat gas flowing through an inside of a heating gas passage with a PTC element, a gap passage (60) forming at least part of the heating gas passage (59) is formed between an inner peripheral surface of a base tube portion (42a) having the PTC element (43) disposed on an outer peripheral surface thereof and an outer peripheral surface of an insertion tube (61) inserted in the base tube portion (42a). Accordingly, it is possible to provide a pressure reduction valve for LPG fuel attached with a PTC heater unit capable of improving efficiency of heating using a PTC element.

The invention relates to a light-receiving element for receiving light reflected at an optical recording medium, an optical head using the element, and an optical recording/reproduction apparatus using the element. The invention provides a light-receiving element capable of preventing deterioration of an electrical signal obtained through photoelectric conversion of received light, an optical head using the element, and an optical recording/reproduction apparatus using the element. The light-receiving element includes a light-receiving portion formed on a silicon substrate and a cover layer formed with a thickness that is greater in a non-light-entrance region around the light-receiving portion than in a light entrance region above the light-receiving portion when viewed in a normal direction of a substrate surface of the silicon substrate. Two outer surfaces on a light entering side of the non-light-entrance region are inclined such that their height decreases toward the light entrance region.
