Abstract: PURPOSE:To prevent unlighting due to cutting of sealing metal foil by forming a thin section at the base of a large electrode to be sealed at the sealing section of an air-tight container made of silicon glass while tapering such that the tip side will be thicker. CONSTITUTION:The base end section 8a of an anode 8 is sealed to the other sealed section 3A where an approximately flat thin section 9 is formed at the base end section 8a while being tapered such that the point (a) will be thick at the point (b) at the tip section 9a side when viewed from the direction of the thickness to form a wedge. 6A and 6B are quite thin sealing metal foils made of molybdenum holding a silicon member 5 of separator glass similarly with the cathode 4 side where one end is connected through platinum to the anode 8 while the other end is connected to an external lead-in member 7A. Since the thick section 9 of the anode base end side is formed into wedge-shape having thicker section at the tip section 9a side, the thick section 9 is wedged by the silicon glass at the sealing section 3A even upon expansion/contraction of the anode 8 due to lighting/unlighting of lamp, resulting in relaxation of expansion/contraction.

Then, the whole periphery of the device mounting region of the light element assembly 2 wherefrom external connective terminal regions are excluded is so sealed by a transparent resin 14' that a recessed hole 14b having a convex semi-spherical lens 14a in its central part whose size is the same as an optical- fiber inserting part is formed in the opposite position to a light receiving element 12. Thereby, a rectangular block-form transparent resin body 14 is formed. Thereafter, a shielding piece 21-5 of a lead frame 21 is so bent that the surface of the transparent resin body 14 is contacted therewith and is covered therewith. In this manner, the light element assembly 2 is configured. Thereby, even when a part of the incident light signal of the light receiving element 12 is projected on the IC chip 13 provided in close proximity to it, the light signal is cut off by the opaque resin 24, and any noise is suppressed.

Abstract: PROBLEM TO BE SOLVED: To suppress the faceting of a far-ultraviolet ray resist pattern by dry-etching a conductive layer after removing an antireflection film by having the film irradiated with the plasma of a mixed gas and forming a mask by hardening the resist pattern. SOLUTION: A hardened layer is formed on the surface of a resist pattern 45 by exposing the pattern 45 to Ar plasma, the plasma of a mixed gas of Ar and CF4, or N2 plasma. In the plasma of a mixed gas of Cl2 and BCl3, an antireflection film 44 is patterned by using the resist pattern 45 as a mask. In addition, a wiring pattern is formed by patterning a wiring layer 43 by using the resist pattern 45 as a mask. While the wiring pattern is formed, no faceting occurs in the resist pattern 45. In addition, the resist pattern 45 is removed by ashing in an ashing chamber. Therefore, the pattern density dependence of the etching shift and pattern width can be avoided.

Title: Epoxy resin composition
Inventor: FUJITA HIROSHI
IPC: C08G59/20
Filed: 1992-09-25
Abstract: PURPOSE:To improve the solder stress resistance of a semiconductor package at mounting on a board by using specified epoxy resin and a specified naphthol resin hardener for lowering the elastic modulus of a molded item, the quantity of water absorption, and the thermal expansion coefficient. CONSTITUTION:This epoxy resin composition consists of epoxy resin, which contains 30-100wt.% epoxy resin expressed by formula I (R1-R8 are the same or different atoms or groups being selected from among hydrogen, halogen, and an alkyl group) to a total quantity of epoxy resin, a naphthol resin hardener being expressed by formula II (R is a group or an alkyl group which has aromatic rings) to a total quantity of hardener, an inorganic filler, and a hardening accelerator. Since the biphenyl-type epoxy resin expressed by the formula 1 is low in viscosity in fused condition and is excellent in fluidity at transfer molding, fused silica powder of compositions can be mixed much, so thermal expansion and water absorption are reduced, and the solder stress resistance can be improved.

Title: Detection method for tunnel excavation position
Inventor: HOSAKA HIROSHI
IPC: E21D9/06
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To measure tunnel excavation position highly accurately without any influence of excavation vibration and any increase in error due to measurements over a long time by measuring azimuth with a gyro compass during the intermittent stoppage of an excavator and processing the azimuth so obtained for analysis. SOLUTION: An excavator 1 is stopped immediately after the tilt of a cutter 5, and the bearing is measured with a gyro compass 2 during the rest of the excavator 1. Bearings not measured are obtained via linear interpolation. Also, the cutter 5 is tilted at bearing conversion tilt points A, B and C, and the bearing is measured with a gyro compass 1 at measurement points (b), (d) and (f), and (c), (e) and (g), respectively immediately before and after the points A, B and C. Measurements are also performed about points (a) and (h) at excavation start and end points O and D. During the operation of the excavator 1, the gyro compass 2 does not output a correct azimuth, due to the occurrence of a heavy vibration, but correct measurements can be performed by stopping the excavator 1 only during the measurements.  The azimuth changes discontinuously at the tilt points, but measurement values can be correctly interpolated, when an azimuth is measured immediately before and after the tilt points.
