摘要:
A process for regenerating electroless plating bath comprising the steps of:(i) continuously or intermittently taking out a part or the whole of chelating agent-containing copper electroless plating bath from an electroless plating tank, followed by removing off the copper ion content from said bath;(ii) acidifying the thus obtained solution for precipitating the chelating agent therefrom and recovering the precipitated chelating agent;(iii) supplying said recovered chelating agent to an anodic cell separated by an exchange membrane from a cathodic cell having cathode, said anodic cell having copper anode, wherein in case a neutral or alkaline electrolyte solution is supplied to said cathodic cell said partitioning membrane is an anion exchange membrane or cation exchange membrane, while in case an acidic electrolyte solution is supplied to said cathodic cell said partitioning membrane is a cation exchange membrane, and applying direct current between both electrode; and(iv) then, recycling the solution within said anodic cell to said electroless plating tank, and a regenerating apparatus of electroless plating bath including(a) a copper-precipitating means for decomposing the copper chelate contained in the electroless copper plating bath and for precipitating the copper ion,(b) a chelating agent-recovering means for changing the pH of the solution to precipitate the chelating agent and recover, and(c) an electrolytic means comprising an anodic cell and a cathodic cell separated by means of an ion exchange membrane, said anodic cell having a copper anode therein, said cathodic cell having a cathode therein.

Hydrocarbons are reacted with a tri-halogenoacetate of the formula ##EQU1## wherein X, Y and Z each represents a halogen atom and M represents a mono valent metal of group Ib to form the corresponding complexes, and then the thus formed complexes are decomposed to selectively separate the desired hydrocarbon components. The used tri-halogenoacetate also is recovered by the decomposition of the complexes.

A steering device (1) includes: a steering member (4) that is provided in a vehicle (2) and configured to be rotationally operated; an actuator (8) that generates a torque assisting a steering operation on the steering member (4); a detection device (9) that detects a torque applied to a steering shaft portion (5) that rotates together with the steering member (4); and a steering control device (11) that performs vibration suppression control to suppress vibrations transmitted to the steering member (4) by adjusting a torque generated by the actuator (8), on a basis of a detected torque that is a torque detected by the detection device (9). The steering control device (11) controls the actuator (8) such that a torque of a frequency band in a first predetermined range, which corresponds to the detected torque is not suppressed.
摘要:
When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.
摘要:
To downsize a drying device that blows gas on a sheet to dry the sheet, a printing apparatus that includes a print head of an inkjet type is provided with a drying unit that dries a sheet printed by a print head. The drying unit has a plurality of conveying rollers that support the sheet; a conveying belt that conveys the sheet; and a nozzle that is arranged between the plurality of conveying rollers in a direction of the conveyance of the sheet by the conveying belt and blows gas toward the sheet. The nozzle has a blowout port and the blowout port is tilted with respect to a surface of the sheet, which is supported by the conveying rollers.

In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.
