Abstract: PURPOSE:To reduce to the minimum both the defocusing in a mark detection optical system and the decrease of alignment accuracy due to a leveling operation by a method wherein an auto-focus or a auto-leveling mechanism is additionally provided to an off-axis type mark detector. CONSTITUTION:A wafer alignment system WGA is arranged at the position separated by maintaining the prescribed interval from the optical axis AX1 of a projection lens PL. Then, the wafer to be subjected to a superposition exposure is shifted to the point located under the alignment system WGA, and a mark detecting operation is conducted. When the mark is detected, the main control system 42 is switched so that the signals Fsg2 and Lsg2 will be selected by a selector circuit 40. Accordingly, the main control system 42 responds the selected signal Fsg2 and servo-controls a motor 14, and the height of a Z-stage ZS is adjusted so that the surface of the local region containing the wafer W mark will be optically coincided with the best image formed plane of an objective lens 28. At the same time, driving sources 10a and 10b are servo-controlled in response to the selected signal Lsg2, and the inclination of a stage LS is adjusted in such a manner that the best image formed plane of the equivalent projection lens PL and the surface of the local region containing the wafer mark are optically paralleled.

Title: Manufacture of molded object
Inventor: AOYANAGI SHIGERU
IPC: B28B3/02
Filed: 1987-12-18
Abstract: PURPOSE:To enable the object with a groove pattern to be easily molded in uniform strength by a method in which non-flowable material is almost uniformly developed on the whole molding surface of the template provided with recessed and projected parts, and it is precompressed, and then after whole outer layer has been scraped and smoothed, new material is developed on said non-flowable material almost uniformly and is compressed. CONSTITUTION:Material 3 is developed on the whole molding surface of a template 1 in almost uniform developed density, and then the material is precompressed by a press. Next, the outer peripheral layer of the pressurized surface side of the material after its precompression is scraped and smoothed by a brush roll 30. Next, new material is developed on the whole outer layer of the material after smoothing in almost uniform developed density, and then said material is compression-molded by a press. The process after precompression is repeated until the material on the template is brought in almost uniform developed density. Consequently, the increasing tendency of compression ratio in press molding process in the projected parts 1B, 1C of the template 1 is mitigated, and the compressed density, i.e. the strength of the molded object 2 becomes uniform in each part. The material 3 is made by mixing the cement composition as curable material with the wood chip flake as reinforcing material and water, etc.

Abstract: PROBLEM TO BE SOLVED: To judge the recording specification of a reproducing disc, and realize initialization process by holding content of the read-in area read from a CD with a read-in information temporary holding means, holding content of the read-in area with a read-in information holding means and collating these contents to determine whether these pieces of information are matched or not to individually recognize a CD. SOLUTION: A control means 5 reads content of read-in area of a compact disc into a read-in information temporary holding means 2. Regarding the practical process to read data in a compact disc, the content of it depends on the operating system or BIOS employed by the system. The read-in information read subsequently is compared with all pieces of read-in information being held in the memory area in the read-in information holding means 4. In this case, when there is no information being matched, the inserted compact disc is determined as a compact disc not yet registered and it is registered to the read-in information.

Title: Fixing device
Inventor: TANABE TAKESHI
IPC: G03G15/20
Filed: 1988-12-20
Abstract: PURPOSE:To prevent picture soiling caused by the attaching of offset developer to a transfer material by providing a reciprocating mechanism which relatively reciprocates a fixing roll and a cleaning mechanism in nearly the bus direction of a fixing rotor. CONSTITUTION:Gears 22 and 23 rotate by means of the drive source of a main body; an eccentric cam 21 rotates by the rotation of the gear 22 to convert rotational to reciprocating motion; thereby a web unit is reciprocated, and a web 5 is reciprocated in the bus direction of the fixing roll. Consequently, developer can be wholly collected in the space of ruggedness on a web surface. This improves the capacity of the web 5 to collect developer without improveing the web 5, and prevents picture soiling caused by the attaching of offset developer to a transfer material.

Abstract: PROBLEM TO BE SOLVED: To provide a pressure contact terminal having a pressure blade which can be conducted to wires with reduced electrical resistance. SOLUTION: A pressure terminal 1 of this invention has a pressure contact 4 in which pressure blades 9 are disposed opposite to each other. The pressure blades 9 are downwardly extended in a vertical direction from a guide surface 9a inclined downwardly toward a centerline of the wire 7.

Title: Illuminator and projection type display device using the same
Inventor: SUGAWARA SABURO
IPC: H04N5/74
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To improve illumination efficiency in the case of using plural light sources by providing an optical system whose action for compressing incident light in the arraying direction of plural light sources is larger than the action for compressing it in a direction perpendicular to the arraying direction between the light source and a lens array system. SOLUTION: Cylindrical lenses 21 and 22 whose action for compressing luminous flux in the arraying direction of plural light sources is larger than the action for compressing it in the direction perpendicular to the arraying direction are arranged between the light sources 1U and 1L and a 3rd optical device 3. Then, two light sources 1U and 1L and parabolic mirrors 2U and 2L are eccentrically arranged to be nearer to the optical axis AA of an illumination optical system, and the luminous flux is guided to a 1st lens array 3 by compressing the diameter of the luminous flux in the arraying direction by a pair of cylindrical lenses 21 and 22.  Thus, high-illuminance parts on the emitting surface of a lens array 4 are distributed to the vicinity of the optical axis AA of the illumination optical system though two light sources are used, and the illumination efficiency in the case of using two light sources is improved.

Title: Method and device for connecting capacitor
Inventor: BENTANI HIROYUKI
IPC: H01G2/02
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To extremely easily and surely connect a large-sized capacitor to a substrate. SOLUTION: When a method and device for connecting capacitor are used, the need of manual soldering work can be eliminated and the labor and time required for the soldering work can be saved, because a capacitor 1 can be connected to a substrate 3 by simply inserting the capacitor 1 into the substrate 3 and a socket housing 3. When the capacitor 1 is inserted, in addition, no improper contact occurs between the contacting piece 42 of the housing 4 and the electrode 2 of the capacitor 1, because the electrode 2 is surely brought into contact with the piece 42. Moreover, when the soldering work becomes unnecessary, no such a trouble as the stripping of the circuit pattern of the substrate 3 occurs, because the heat of a soldering iron is not transmitted to the substrate 3.
