Title: Device and method for detecting abnormality in spot welding equipment
Inventor: SHIRAKAWA YUSAKU
IPC: B23K11/24
Filed: 1993-12-10
Abstract: PURPOSE:To examine in a short time where is the cause of abnormality in a spot welding gun unit side or in a welding timer side without disassembling the spot welding equipment into each composing part and performing visual investigation of the cause. CONSTITUTION:The equipment is constituted by connecting a welding gun unit having a welding transformer to a welding timer 2 connected to a controller 1 through a cable 5. At a time of detecting the abnormality of the spot welding equipment, instead of the welding gun unit having the welding transformer, a dummy electric part 10 having the same electric characteristics with the above is connected to the welding timer 2, and the constitution is made so that the judgement can be done by whether the cause of abnormality is in the welding gun unit side having the welding transformer or in the welding timer 2 side with whether the welding timer 2 is normally energized or not.
Patent JP-H09130188-A (JP)
Title: Thin electronic component
Inventor: OOFUJI TAKEMICHI
IPC: H03H9/02
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness and to shorten the welding time for an electronic parts by specifying the thickness of a terminal in the direction rectangular to the forming direction of a terminal inserting hole. SOLUTION: A base 26 uses a flat plate having a rectangular plane shape, and the terminal inserting holes 32 are formed at the positions near the corner parts of the base 26. Each of these holes 32 has a round shape of inner diameter A3 of about 1.1mm. Every terminal 27 has a short column shape and a diameter B3 of about 0.6mm and is placed at the center of the hole 32 in parallel to the forming direction of the hole 32. Then B3 /A3 ≈55% is satisfied between the diameter A3 of the hole 32 and the diameter B3 of the terminal 27. Thus the diameter of the terminal 27 is set at 50% or more compared with the inner diameter of the hole 32. As a result, the contact area is increased between every terminal 27 and an insulator 28 and the insulator 28 can receive the external force, if applied to the terminal 27, in a comparatively wide area.  Thus an electronic component of such a constitution is not easily damaged.

Title: Heat treatment of fluorite single crystal and processing method for fluorite single crystal
Inventor: SAKUMA SHIGERU
IPC: B24B1/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To diminish operation time without damaging fluorite single crystal by specifying heating rate up to a preferred temperature in a specific range. SOLUTION: When heat-treating fluorite single crystal, heating rate up to a preferred temperature lower than that of its melting point is set so as to become >=20 deg.C/h. and <150 deg.C/h. When the heating rate is 100 deg.C/h., the yield of fluorite single crystal is excellent as much as that when the heating rate is <=20 deg.C/h. When the heating rate is >=50 deg.C/h., the heating operation time becomes <=1/2 and is extraordinarily shortened. The preferred temperature is preferably the highest one in the total excursion of heat treatment. The heat treatment of fluorite single crystal is usually conducted at about 1,000 deg.C and the above heating rate for heating the single crystal up to the set temperature is adopted without any problem even when such high temperature is set, which leads to the improvement in efficiency because one-step heating rate up to the highest temperature is adopted.

Title: Projection aligner
Inventor: NISHIKAWA HITOSHI
IPC: H01L21/027
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To hold an optical element of a projection aligner which uses exposure light of 300 nm or below of wavelength to an object without using an adhesive. SOLUTION: Optical elements L1, L2 of a projection optical system 23 are held without using an adhesive by being pressed against a holding tube 51 by flat springs 61. Optical elements L3-L5 of the projection optical system 23 are held without using an adhesive by being pressed against a holding tube 52 with screw rings 53. ArF excimer laser is cast on a reticle 16 to transfer a pattern on the reticle 16 onto a wafer 25 through the projection optical system 23. Even if ultraviolet rays are cast on the reticle, the optical elements are not contaminated since no adhesive is used and therefore there is no gasification of an organic solvent.

IPC: G02B13/18
Filed: 1989-12-01
Abstract: PURPOSE:To provide the zoom lens which is compact, good in performance and low in cost by constituting the 2nd group of a piece of negative lens having an aspherical face to constitute the zoom lens which executes variable powers by changing the spacing between the positive 1st group and negative 2nd group successively constituted from an object side. CONSTITUTION:The 2nd group of the zoom lens, which is constituted, successively from the object side, of the 1st group having a positive refracting power and the 2nd group having a negative refracting power and executes the variable powers by changing the spacing between the 1st group and the 2nd group, is constituted of one element of the negative lens having the aspherical face. While the aspherical face of the 2nd lens may be formed only on the image side face or may be used on both faces without any optical problems, the aspherical face is provided on the object side face of a large curvature by taking the ease of production into consideration. The generation of astigmatism on the telephoto side from an intermediate focal length is suppressed in this way. In addition, the generation of chromatic aberrations is suppressed by constituting the positive 1st group of >=2 elements of positive lenses and >=1 elements of negative lenses.

IPC: H01S5/068
Filed: 1987-12-10
Abstract: PURPOSE:To stabilize oscillating wave length by dividing stripe electrode to provide an oscillating area and a wave control area. CONSTITUTION:An active area composed of compound semiconductor single crystal layers such as GaAs/AlGaAs is slenderly formed in the direction of reflecting end faces 2 of both ends, and stripe electrodes 3a, 3b are provided right above. Oscillation is performed with constant wave length by supplying current necessary for oscillation on an electrode 3a. When at this time the current of the electrode 3a is increased and surrounding temperature is heightened, oscillating wave length is also enlarged. In order to control this, the oscillating wave length is returned up to former wave length and stable laser light can be obtained if the current of the electrode 3b is set to decrease by a current control circuit 5.

Title: Apparatus and method for printing bit image data
Inventor: ORII SATORU
IPC: H04N1/034
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To shorten a printing operation thereby improving a printing speed and effectively use a memory resource. SOLUTION: An upper end (HPP) and a lower end (LP = HPP + standard data height BDH) of bit image data are controlled by a printing control part. A data-judging part judges whether or not the upper end and lower end of the bit image data are accommodated in a band height range. An upper end of the band height range is a logical set position rYPOS related to a data- selecting process, and a lower end of the band height range is a position of rYPOS + head height HEADHT. When the upper and lower ends are judged to be in the band height range, the bit image data are selected as an object to be developed and printed by the band and, developed to an output buffer. Accordingly, a plurality of lines can be printed at the same time by one band, so that a memory resource can be effectively utilized.
