Title: Preparation of multi-layer sheet
Inventor: EGASHIRA AKIHIKO
IPC: B29C48/305
Filed: 1985-09-04
Abstract: PURPOSE:To improve the yield of the product and prevent any limintation on the type of the resin to be used, by using a specified T-die having a specified value of the ratio of the width of the resin flowing-out hole to the maximum width of the resin flowing path. CONSTITUTION:A T-die D, whose rato R of the width W1 of the resin flowing- out hole to the maximum width W2 of the resin flowing path is R=W1/W2<1, is used. As the T-die, in the structure of which the resin flowing path is made narrower toward the resin flowing-out hole, is used as above described, the thickness of each layer of the laminated sheet becomes very close to the set value both at the center of the width and in the nearby of both edges. The cut amounts of both edges of the laminated sheet thereby may become less and the yield of the product becomes better.

Inventor: OGAWA TAKESHI
IPC: G02B6/122
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To decrease the crosstalks between optical waveguides formed in congestion. SOLUTION: The portions exclusive of the light incident ends and light exit ends of the individual optical waveguides consisting of cores 4p composed of a high-polymer material and clads 6 composed of the high-polymer material enclosing the same are enclosed with light absorption layers 8. Even if scattered light is radiated from the certain optical waveguide, this light is absorbed by the light absorption layers 8 and is, therefore, not coupled to the other optical waveguides. The clads 6 are formed by integrally patterning lower clad layers 3p and upper clad layers 5p holding the tops and bottoms of the cores. The light absorption layers 8 comprise a lower light absorption layer 2 and an upper light absorption layer 7 holding the tops and bottoms of the clads 6.  When a semiconductor laser beam of a near IF region is assumed as propagation light, the cores 4p and the clads 6 may be respectively composed of the chain org. high polymer and the light absorption layers 8 of the material mainly composed of a cyclic org. high polymer.

Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To map packet scheduling functions in a packet processor on a task scheduling function in an operating system by executing lateral task scheduling based upon task priority. SOLUTION: A task allocating task (dispatcher task) 1G to a receiving packet, a protocol processing task 1H for a packet 1, a protocol processing task 1I for a packet 2 and a protocol processing task 1J for a packet 3 are prepared as tasks. An operating system 1F has a lateral task scheduling function and executes a task with the highest priority out of the tasks 1G to 1J in processing waiting states.

Title: Manufacture of semiconductor device
Inventor: HIRAKI MITSUMASA
IPC: H01L21/306
Filed: 1992-07-23
Abstract: PURPOSE:To obtain an layer insulating film having a constant thickness in the chemical-mechanical polishing method. CONSTITUTION:An oxide film 25 is grown under normal temperature on a semiconductor substrate 21 on which a wiring pattern is already formed, a plasma nitride film 24 is then grown and a plasma oxide film 26 is moreover grown thereon. Next, when the entire part is etched back by a chemical- mechanical polishing method, a nitride film on the wiring acts as a stopper of etching, the oxide film on the non-wiring area is no more etched and the stepped portion between the wiring part and non-wiring part can be eliminated, providing a flat layer insulating film. Thereby, the thickness of the layer insulating film is uniformed by using a nitride film as the etching stopper. Moreover, since a thick insulating film can be formed on the wiring during the polishing process, any stress is not applied to the wiring and reliability can also be improved.

This lens 3 is provided on the optical path extending from the light source 1 to the observation surface 7 through a reference optical element 5 and the optical path extending from the light source 1 to the observation surface 7 through a body 6 to be measured. Then, parallel luminous flux which is generated through the lens 3 is used as the reference luminous flux of a trailing-stage optical system 4 for measurement and luminous flux to be inspected. Reflected luminous flux from the element 5 as to the reference luminous flux and luminous flux which is reflected by the body 6 to be measured and transmitted through the element 5 as to the luminous flux to be inspected are both pieces of luminous flux which have uniform energy intensity distributions in their wave fronts and the image which has excellent contrast over the entire measurement visual field is obtained.
