摘要:
The present invention is concerned with improved means for etching circuit structures on printed circuit board or wafer substrates of copper or copper alloys in a manner effectively removing unwanted copper from such circuit structures leaving behind a smooth copper surface applying an etching solution containing an Fe(II)/Fe(III) redox system and sulfur containing organic additives. It is an advantage of the present invention that the solution can also applied for plating of copper prior to etching.

The present invention relates to an information processing apparatus capable of accurately controlling DMA transfer of a plurality of pieces of data present in a memory with a simple hardware configuration, and an information processing method for use therewith. A memory 33 is provided with a descriptor table T0 corresponding to a queue Q0 and a descriptor table T1 corresponding to a queue Q1. In registers R0 and R1 of a descriptor controller 51, the descriptor number constituting the descriptor table T0 and the descriptor number constituting the descriptor table T1 are recorded, respectively. In caches C0 and C1 of a descriptor obtaining section 52, descriptors of the descriptor table T0 and descriptors of the descriptor table T1 are recorded, respectively. A descriptor selector 53 selects one of the caches C0 and C1 in accordance with a predetermined rule. The present invention can be applied to all electronic apparatuses for performing DMA transfer.

Provided is a cleaning device having a compact structure.A recovery unit (17) is configured such that dust collection boxes (76, 77) are disposed with respect to a cleaning brush (6) and a metallic roller (7), respectively. A cleaning blade (9) is fixed to a blade holder (79) via a bolt (78). When the recovery unit (17) is incorporated in a frame unit, the recovery unit (17) is moved in a predetermined direction so as to be brought into contact with a positioning section (14Bbb) of a side plate 14B of the frame unit (11). When the recovery unit (17) is moved, a fixing bolt (85) is loosened so that a straight portion (86a) of a fixed washer (86) is aligned with the vertical direction, and then, the fixing bolt (85) is tightened so that the recovery unit is fixed. On the other hand, when the recovery unit (17) is fixed, the fixing bolt (85) is loosened so that the straight portion of the fixed washer (86) is aligned with the horizontal direction, and then, the fixing bolt is tightened so that the recovery unit is fixed.

An imprint apparatus for transferring a pattern to an imprint material using a mold includes a substrate holding mechanism and a control unit. The substrate holding mechanism is configured to be divided into a plurality of areas, capable of varying an attracting force for attracting the substrate in each of the areas and to hold the substrate. The control unit is configured to, when a plurality of shots is formed on the substrate, control an imprint operation of transferring the pattern to the plurality of shots which are not adjacent to one another, makes the attracting force in the area of the substrate holding mechanism corresponding to the shot to which the pattern is transferred among the plurality of areas smaller than the attracting force at the time of the imprint operation and suck the substrate.

The present invention provides a lock-up clutch mechanism for a torque converter, comprising a lock-up piston and a front cover having an engagement surface capable of being engaged with the lock-up piston and in which a friction material is stuck to wither one of the lock-up piston and the front cover and in which engagement and disengagement are performed in accordance with a hydraulic pressure difference between the front cover and the lock-up piston and wherein the friction material includes a first flat friction surface disposed at an outer diameter side and a second tapered friction surface disposed at an inner diameter side and further wherein, when the lock-up piston and the front cover are slip-controlled, the first friction surface is engaged with uniform face pressure, and, when the lock-up piston and the front cover are substantially integrally joined with a great hydraulic pressure difference under slip control, maximum face pressure is generated at a border between the first friction surface and the second friction surface.
摘要:
A process for continuously producing a thermoplastic copolymer, in which a copolymer (A) containing unsaturated carboxylic acid alkyl ester units and unsaturated carboxylic acid units is produced and in succession heat-treated to perform intramolecular cyclization reaction by dehydration and/or dealcoholization reaction, for producing a thermoplastic copolymer (B) containing glutaric anhydride units and the unsaturated carboxylic acid alkyl ester units. The obtained copolymer is excellent in heat resistance and colorless transparency and very small in foreign matter content.

摘要:
The present invention relates to an information processing apparatus, an information processing method, and a program capable of simplifying an interrupt processing and reducing a time necessary to the interrupt processing. An interrupt generation unit 140 generates an interrupt signal. An interrupt status holding unit 142 stores an interrupt status showing a cause of generation of the interrupt signal. An interrupt status supply unit 141 supplies an interrupt status stored by an interrupt status holding unit to a RAM and causes the RAM to store it. A CPU executes a predetermined processing in response to the interrupt status stored to the RAM. The present invention can be applied to, for example, a network card.
