Title: Fluoride glass optical waveguide
Inventor: FURUGUCHI MAKOTO
IPC: H01S3/17
Filed: 1992-07-03
Abstract: PURPOSE:To obtain a fluoride glass optical waveguide capable of optical amplification of high gain by pumping with a general-purpose semiconductor laser of low output, by containing Nd and further Yb in addition to Pr in core glass of a fluoride glass optical waveguide composed of ZBLAN based glass. CONSTITUTION:In a fluoride glass optical waveguide wherein core glass or clad glass is mainly composed of ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) based fluoride glass, and Pr is contained in at least the core glass, Nd also is contained in at least the core glass. When the core glass is further doped with Yb, energy is effectively transmitted from Nd to Pr, because electron structure of Yb is intermediate between Pr and Nd. Hence a fluoride glass optical waveguide capable of high gain optical amplification of 1.3mum by pumping with a general-purpose low output semiconductor laser having an output wavelength except 1.02mum can be obtained.

Inventor: STROMSKY ROLAND
IPC: F01M9/10
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To suck oil collected together in an inner chamber of a cylinder head at the time of strong acceleration and deceleration or curve traveling so as to return the oil into an oil reservoir container by connecting a second aggregating pipe passage to the innerchamber for the cylinder head only in a rear region or a front region opposed to the cylinder head.

However, oil is sucked through a horizontal direction passage 16 arranged within the chain box 22, and oil is discharged from the cylinder head. It is guaranteed that respective horizontal direction connecting parts are positioned downward the height of an oil surface by arranging the aggregating pipe passage in such an above constitution.

Abstract: PURPOSE:To prevent a conductive wiring layer and a semiconductor substrate from being short-circuited if a contact between polycrystalline silicon layer and a conductive wiring layer is formed by providing a second conductivity type impurity diffused layer on a lower region of a contact hole. CONSTITUTION:An impurity diffused layer 18 is formed on a semiconductor substrate l under a contact hole 8. In the layer 18, an opposite conductivity type impurity to that to the substrate l is doped, and a p-n junction is formed in a boundary to the substrate 1. For example, when the substrate 1 is mounted and a positive bias voltage is applied to a conductive wiring layer 9, a reverse bias is applied to the p-n junction. Accordingly, even if the layer 9 is connected to the substrate 1 through a polycrystalline silicon layer 3 and an oxide film 2 at the bottom of the hole 8, an insulation between the layer 9 and the substrate l is obtained, no current leakage occurs through the substrate l. Thus, a desired bias voltage is effectively applied to the layer 3 as a field shielding electrode, and shielding characteristic is held excellently to provide satisfactory shielding characteristic.
