Title: Method of manufacturing sumiconductor device
IPC: H01L21/321
Filed: 1992-03-16
Abstract: PURPOSE:To form a bump electrode by electrolysis plating having uniform current density and manufacture a thing which can perform wireless bonding having high reliability by a method wherein a P type layer is provided on the reverse side of an N type semiconductor substrate forming the bump electrode by the electrolysis plating and the surface is connected with the cathode. CONSTITUTION:A ground metallic film 6 is spread on one surface of a N type semiconductor substrate 1 and an end part of a P type layer 3 formed on the other surface of the substrate 1 is connected with the ground metallic film 6. The ground metallic film 6 is coated with a mask 8 having an opening part. The ground metallic film 6 exposing in the opening part of the mask 8 is opposed to the anode 11 within an electrolyte 9 and the negative pole is connected with the P type layer 3 to perform electrolysis plating, by which a bump electrode 13 is formed on the exposed ground metallic film 6. Thus, as a plating current is prevented by a PN junction, it does not flow within the substrate and flows to the cathode from the ground metallic film through the P type layer. Accordingly, scattering of the plating current due to uniformity of current density within the substrate is not caused.

Title: Fluorescent lamp
Inventor: SHIYUUBOU MASAKI
IPC: H01J61/54
Filed: 1979-05-07
Abstract: PURPOSE:To obtain a fluorescent lamp free of faults, e.g., blackish brown spots, by suppressing the occurrence of blakish brown spots by covering a transparent conductive film with a fluorescent substance containing a specific amount of manganese as an activator. CONSTITUTION:The inner surface of the glass tube is covered with the transparent conductive film 2 composed of tin oxide, etc., and then with the fluorescent substance 3 containing 0.5wt% or less manganese as an activator. Thus, when the fluorescent substance suffers a current impact, the formation of blackish manganese dioxide from the reaction of trace oxygen present in the tube with manganese is reduced and therefore blackish brown spots are greatly suppressed. Thus, a fluorescent lamp having no trouble, e.g., the occurrence of blackish brown spots, can be obtained.

Title: Focus adjustment system for infrared image pickup device
Inventor: NAKAZATO HIDEAKI
IPC: G02B7/28
Filed: 1986-03-13
Abstract: PURPOSE:To place a focus in the best state by monitoring the differentiated value of the absolute value of a video signal while moving a focus adjusting mechanism, obtaining the negative as a focus matching position, and stopping a focus adjusting mechanism at the point of time. CONSTITUTION:A lens for focus adjustment is moved by the focus adjusting mechanism 10 in a predetermined direction, e. g. forward direction and the output of one detecting element 16 which constitutes a two-dimensional infrared detector 3 is passed through an amplifier 18 to generate an absolute value waveform by a squaring circuit 19. This waveform is differentiated by a differentiation circuit 20 to obtain a positive signal when the moving direction of the focus adjusting mechanism 10 is a focusing direction or a negative signal when a defocusing direction. Consequently, the output of the differentiation circuit 20 is decided by a comparator 21 and the focus adjusting mechanism 10 is controlled in such a direction that the polarity is positive; and the point of time when the polarity changes from positive to negative is obtained to stop the focus adjusting mechanism 10, thereby setting the lens at an in-focus point automatically.

The separated mixture is added to an aqueous solution of a mineral acid to decrease the pH to <=3 and the precipitated isoluble 2,6-naphthalenedicarboxylic acid is separated by filtration. The filtrate is concentrated while keeping the pH at <=3 and cooled to crystallize trimellitic acid, which is separated from the liquid by filtration. The filtrate is added with an alkali metal (bi)carbonate and the heavy metal is recovered as a (basic) carbonate.

Title: Dust collecting and removing method
Inventor: OOE HIROSHI
IPC: B03C3/74
Filed: 1983-03-31
Abstract: PURPOSE:To prevent the entry of dust in a filter medium in the stage of collecting dust and to improve the removability of dust in the stage of removing dust by disposing conductive fibers in the position near the surface of the filter medium and running slight electric current through the fibers. CONSTITUTION:A filter medium 5 is made of, for example, polyester fibers, glass fibers, etc. and carbon fibers 6 having 0.1mm. outside diameter are disposed at 1cm intervals near the surface. Slight current of <=1 milliampere flows in the fibers from a 200V DC voltage source. The filter medium is so connected that the electric charge on the surface of the fibers 6 is positive while the dust 7 in dusty air A is electrified to negative potential by the friction with the air in a dust collecting hood, dust collecting duct and the body of a dust collecting material in the stage of collecting dust and therefore the attracting force is generated between the dust 7 and the fibers 6 and the dust 7 deposits on the fibers 6 by concentrating near the same. On the other hand, if the slight current in an opposite direction is run by changing the connection in the stage of removing dust, the dust 7 is easily stripped off.

Title: Laser transmission system and its operation method
Inventor: FISCHER EDGAR
IPC: H04B10/11
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a compact laser transmission system which excels in its operating efficiency by leading the output of a narrow band non-modulated light laser oscillation part to an optical semiconductor amplifier via a polarization holding optical fiber and modulating the supplied current to modulate both phase and amplitude. SOLUTION: A laser beam part 2 serves as a laser diode where a solid body that oscillates the non-modulated light of a narrow optical band is pumped or as a laser diode which is oscillated in a narrow band area via an external resonator. The oscillation output of the laser diode is directly led to an optical semiconductor amplifier 6 by a polarization holding optical fiber 4. The amplifier 6 causes the modulation of phase when it modulates the supplied current at a comparatively low level. Meanwhile, the amplitude can be modulated when the supplied current is modulated at a high level. As the aperture of the amplifier 6 has a special shape, the astigmatism of an output beam 8 is corrected by an optical lens system 10. Then the beam 8 is converted into parallel beams 12 and outputted to the outside.
