Title: Nozzle head for extruder
Inventor: BECKMANN HANS-UDO
IPC: B29C48/30
Filed: 2001-01-15
Abstract: PROBLEM TO BE SOLVED: To eliminate a bank, a deposit and an embrittlement of a molten plastic in a gap between a mandrel of a nozzle head of an extruder and a casing.

Title: Led print head and its manufacturing method
Inventor: AKIYAMA SHOICHI
IPC: B41J2/455
Filed: 2001-01-17
Abstract: PROBLEM TO BE SOLVED: To provide an LED print head in which light enters only from an emission region and a light emitting spot is prevented from enlarging to cause deterioration of image quality. SOLUTION: A micromirror array 3 arranged with a large number of spheroidal micromirrors 4 is disposed in proximity to respective light emitting parts 2 of an LED array chip 1. Each micromirror 4 has such a shape as the opposite end parts in the long axis direction of a hollow spheroid are cut off by planes including focuses Fa and Fb or the vicinity thereof. Since the focus Fa of the micromirror 4 substantially matches the light emitting part 2, diameter of a light emitting spot from the LED array chip 1 does not increase and since unnecessary emission from a part other than the emission region of the LED array chip 1 or unnecessary reflection light are blocked, image quality does not deteriorates.

Title: Selvedge-fixed glass cloth
Inventor: KIMURA YASUYUKI
IPC: D06M23/18
Filed: 2001-01-17
Abstract: PROBLEM TO BE SOLVED: To obtain a selvedge-fixed glass cloth useful for producing high-quality prepregs with high frayproofness and heat resistance, and environmentally favorable. SOLUTION: This selvedge-fixed glass cloth is obtained by coating a given width of each of both the selvedges of a glass cloth with an antioxidant- incorporated polyamide resin for preventing the selvedges from fraying at normal temperatures and even under heating conditions. By the way, since the main solvent of the resin liquid to be used for fixing the selvedges of the glass cloth is water, there occurs no workplace environmental pollution over the total process ranging from its preparation, coating to drying, therefore being also effective from the viewpoint of environmental protection.

Title: Semiconductor device and manufacturing method thereof
Inventor: YAMADA MASAKI
IPC: H01L23/522
Filed: 2001-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce an inter-wiring capacity for improving the performance of a single LSI in a large scale integrated circuit (LSI). SOLUTION: A first inter-layer insulating film 3 for expressing a first wiring layer pattern is laminated on a semiconductor substrate 1, and a second wiring layer pattern is expressed on the first inter-layer insulating film 3. Further, a second inter-layer insulating film 8 of an etching rate different from the first inter-layer insulating film is laminated. Thus, no first inter-layer insulating film 3 is over-etched even if a photomask displaces when etching the second inter-layer insulating film 8. Thus, an etching stopper film of a high specific inductive capacity is not required to suppress an effective wiring capacity. Since a manufacturing process in which an etching stopper film is deposited is not required, the manufacturing process is simplified.

Filed: 2001-01-22
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device and an image forming method, by which the density of a toner images is easily and surely stabilized over a wide range of density. SOLUTION: By forming solid patch images on various patch forming conditions (Va, E and Vb) and then measuring the optical density of the respective solid patch images using a paths sensor, the patch-forming condition matching with high density side target density (OD=1.2) is extracted as 'high density correlation data'. Then, by forming line patch images on the various patch forming conditions (Va, E and Vb) and measuring the optical density of the respective line patch images by the patch sensor, the patch forming condition coincident with low-density side target density (OD=0.2) is extracted as 'low density side correlation data'.  Thus, optimum electrification bias, optimum exposure energy and optimum developing bias are set, based on one correlative data (Va (2), E2 and Vb (2)) belonging to the product set of the high- density side correlative data and the low-density side correlative data.

Title: Apparatus and method for laser ultrasonic inspection
Inventor: NAGATA YASUAKI
IPC: G01N29/00
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To improve the sensitivity for detecting defects in a laser ultrasonic inspection apparatus and a laser ultrasonic inspection method of a type in which laser beams for generating ultrasonic waves and for detecting ultrasonic waves are scanned on the surface of an inspection object. SOLUTION: The radiation timing is controlled so that a laser for generating ultrasonic waves having a narrow pulse width (indicated by a curve (a)) radiates in the vicinity of a peak value of a laser for detecting ultrasonic waves. With the use of a rotary chopper, an inspection object is irradiated with laser beams for detecting the ultrasonic waves (indicated by a curve b) for only a time width T corresponding to a required flaw detection depth and shielded from the laser beams for the other time not to be irradiated. Accordingly, a temperature rise of an irradiation position of the inspection object before irradiation with the laser beams for generating ultrasonic waves is prevented. Ultrasonic waves can be generated efficiently and the detection sensitivity for ultrasonic echoes resulting from defects is improved.
