Title: Copper plating method
Inventor: HACHISUGA SHUNJI
IPC: C25D5/26
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain copper plating having good quality while assuring a stable deposition rate by adding cuprous oxide to a copper pyrophosphate soln., adjusting the pH to a specific value, installing a non-dissolved copper and immersing a steel product which is cathode into the soln. SOLUTION: The copper pyrophosphate soln. 12 is put into a tank 11 for plating. This tank 11 is provided with the non-dissolved copper 14. A steel wire 15 as the cathode is supplied and immersed into the soln. An anode 14 and the wire 15 are connected to a current rectifier 16 and a current is passed between both. The copper pyrophosphate soln. 22 is also put into a dissolving tank 21 for replenishment. Metal copper 14 is oxidized in a thermal oxidation furnace 25 and is made into the cuprous oxide 26. The cuprous oxide 26 is added as a supply source for copper via a hopper 27 to the soln. 22 in the tank 21. The amt. of the cuprous oxide 26 to be added is so controlled that the pH of the soln. 22 is maintained at 8 to 9.  Since the non-dissolved copper 14 is usable, the spacing between the anode 14 and a material 15 to be treated is maintained constant and the good copper plating is executed.

Title: Semiconductor device
Inventor: MATSUDA HIDEO
IPC: H01L29/74
Filed: 1983-05-26
Abstract: PURPOSE:To prevent the breakdown of forward directional overvoltage by a method wherein the emitter of a transistor surrounded by an N type emitter is short-circuited with a P type base, so as to make the collector-emitter withstand voltage smaller than a forward directional blocking voltage. CONSTITUTION:Since a region 55 of an auxiliary transistor 62 is formed more deeply than a region 54 of the main thyristor 61, the impurity concentration of a region 52 in the boundary surface between the regions 55 and 52 is smaller than that of the region 52 in said surface between the regions 54 and 52. Therefore, the generation of dv/dt in the forward directional voltage between the anode electrode 57 and the cathode electrode 58 induces id1 and id2, thus generating the potential drop of V1=id1XRPB, when it becomes over the difference of diffused potential, the auxiliary transistor 62 turns on, a current IE is supplied, and accordingly the main thyristor 61 turns on. On the other hand, when a region 56 is so formed as to reach inside a region 51, a current IBD flows at the time of the reach of the anode-cathode voltage to the collector-emitter breakdown voltage, and an emitter current IE is supplied to the main thyristor 61, resulting in turning on. As a result, it becomes possible to equip the titled device with the function of protection against both the dv/dt breakdown and the breakdown of forward directional overvoltage.

Title: Antimicrobial product and composite
Inventor: SOROMON ROOZENBURATSUTO
IPC: A01N59/12
Filed: 1990-04-06
Abstract: PURPOSE: To obtain a complex to form an antibacterial iodine carrier having high body fluid absorptivity, strength, flexibility and hydrophilic property by applying a composition including acetalized polyvinyl alcohol complexed with iodine capable of emitting free iodine in the presence of water. CONSTITUTION: PVA/I forms an insoluble iodine complex to emit iodine either in the presence of significant quantity of water or microorganism. Iodine is emitted in case the PVA/I is put in an arachette consists only of sarains. The iodine would, however, make a balance with the sarains without loosing the iodine from its system. When an organic substance is added to the sarains including this solid complex, 2 or 3PPM-approx. 100PPM of iodine would be emitted. Emitted iodine is next absorbed by the microorganisms and, kills them, causing irreversible reaction. When emitted iodine is absorbed, only in this case, the emission of the iodine wound continue as far as it comes to keep the balance.

Title: Operation of stored type sequence controller
Inventor: NAKADA KAZUE
IPC: G05B19/05
Filed: 1983-05-26
Abstract: PURPOSE:To simplify the operation of a sequencer by storing once the control data into a memory without delivering this data outside until the execution is over with the sequence of a section and then delivering the control data successively through an exclusive AND circuit. CONSTITUTION:A sequencer 8 is provided with a data memory MR which stores temporarily the contents of a register of an ALU (arithmetic logical unit) in addition to an input part I, an output part O, an ALU and a program memory MC. When the sequence control is started, the ALU reads out the information on an SWSa and writes it to the O-th bit of areas Xa-Xc of the memory MR in the form of 1/0. Then the information on a contact Sb is read out to the register of the ALU and then written to said address together with the address information of a relay Xa. Then the contact information Sc is read out and written to the MR together with the information on a relay Xb. When the read/write operations are through with all contacts, the data are delivered successively from the memory MR via an output part O to execute instructions. Thus it is possible to simplify the operation of a sequencer.

Title: Apparatus and method for mounting electronic component
Inventor: TSUBOUCHI YUZO
IPC: H05K13/08
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To eliminate the reduction in the accuracy of mounting position, due to a change of lower end of nozzle accompanying the temperature rise of a transfer head. SOLUTION: A transfer head 22 and a light-emitting part 32 are assembled integrally to the frame of a head part 20. When the transfer head 22 is thermally deformed, a nozzle 24 is inclined, and the light fluxes L and L' emitted from the light-emitting part 32 are inclined at the same angle. The focus of an observation device 40 is focused in the vicinity of the lower end of the nozzle 24 for vacuum-sucking an electronic component. Consequently, the positions of light fluxes L and L' emitted downward from the light-emitting part 32 are observed by the observation device 40, so that the quantity of change is light fluxes L and L' can be considered to be the same as that of the lower end of the nozzle 24. Then the movement stroke of the head part 20 is corrected so as to correct for the shifted quantity, and an electronic component is mounted to a board thereafter.

Abstract: PURPOSE:To form a positive type pattern by mounting the resist layer having the positive type double layer structure on a substrate having a step structure, and by exposing the resist layer with an ionizing radiation. CONSTITUTION:The substrate to be treated is, at first, coated with a resin layer so as to level the step of the substrate. The resin layer is coated with the positive type resist layer contg. a mixture of 30-80pts.wt. cross-linking methacrylate polymer, 10-30pts.wt. partial rudder type silicone resin and 0-40pts.wt. 1,4 bis-(hydroxydimethylsilyl) benzene so as to form the double layer structure. The resist layer is exposed selectively with the ionizing radiation, processed, and open a window to the resist layer. The resin layer located under the resist layer is oxygen plasma-etched using the resist layer as a mask. As the methacrylate resist is heat-crosslinked in a prebake, the silicone resin contd. in the resist composition generates heat fog. In order to prevent the heat fog, the heat-crosslinkable 1,4 bis-(hydroxydimethylsilyl) benzene is added to the composition in the prebake.
