Abstract: A quartz glass crucible which has a non-transparent outer layer formed through melting a natural silica powder and a transparent layer formed in the inside of the outer layer, wherein the transparent layer comprises a natural quartz layer having a thickness of 0.4 to 5.0 mm transparent layer comprising a synthetic quarts glass is formed thereon in the inside of the crucible in the range of 0.15 to 0.55 L relative to L, which is the distance from the center of the bottom of the inner surface of the quartz glass crucible to the upper end thereof along the inner surface thereof. The quartz glass crucible can be suitably used for suppressing the occurrence of vibration and reducing the generation of roughened face in the surface of a crucible, and thus for pulling up a silicon single crystal with enhanced stability.

Abstract: An electronic circuit, for which a coil 22 is disposed being overlapped with a region of a memory array 11, carries out communications by inductive coupling between stacked and mounted chips by means of the coil 22. Because each side of the coil 22 is disposed so as not to be parallel to a word line and a bit line 15, crosstalk between ‘the coil 22’ and ‘the word line 14 and bit line 15’ can minimized. This allows efficiently arranging a coil to carry out communications by inductive coupling between chips to be stacked and mounted.

Abstract: An oil pan assembly is disclosed that includes an oil filter, and an oil pan receiving the filter. The oil pan includes a reservoir defining a drain aperture for selectively draining fluid out of the oil pan, and a wall defining a filter cavity in fluid communication with a receiving passage and a sending passage of the oil pan. The oil pan further includes a filter cover assembly, including a cover securing the oil filter within the filter cavity, a filter drain tube extending from the cover through the filter cavity and into a drain passage, and a plug disposed on the filter drain tube, the plug selectively sealing the drain passage. The drain passage allows fluid communication between the filter cavity and the reservoir. The filter drain tube is configured to receive filtered oil from the oil filter.

Abstract: The present invention relates to a high pressure discharge lamp that includes a pair of electrodes, which face each other in an electric discharge space. Further, an electrode axis of one of the electrodes is joined to a metallic foil in a sealing portion, and two or more grooves are formed in an axis direction on a portion corresponding to the sealing portion on the electrode axis. Furthermore, a remaining portion that lacks grooves is left on the electrode axis in a metallic foil side thereof, and the metallic foil side ends of the grooves are not aligned with each other in the axis direction thereof.

Abstract: Disclosed herein is an electro luminescence display panel having a pixel structure corresponding to an active matrix drive system, including: a reverse bias potential generating portion configured to generate a reverse bias potential in which corresponding one of gradation values of pixels is reflected; and a voltage applying portion configured to apply the reverse bias potential to a gate electrode of a drive transistor composing a pixel circuit adapted to operate for a non-emission time period.

Abstract: A DA converter includes: an analog signal output section that generates an output current and a non-output current according to a value of a digital input signal in response to a gain control signal supplied to adjust gain, and that outputs an analog signal produced by current-voltage conversion of the output current and causes the non-output current to flow to a reference potential; a gain control signal generating section that generates a gain current and a non-select current according to a value of a digital gain control signal, and that generates the gain control signal by current-voltage conversion of the gain current and supplies the gain control signal to the analog signal output section; and a correction current generating section that generates, based on the non-select current of the gain control signal generating section, a correction current that complements an amount of current fluctuation due to changes in gain settings in the gain control signal generating section, and that causes the correction
