A plasma processing apparatus which contributes to reducing required time for maintenance and thereby to enhancing the efficiency of processing and that of apparatus operation is to be provided. A vacuum processing apparatus comprises a vacuum vessel in which a substrate-shaped sample is arranged in an internally arranged processing chamber in which the pressure is reduced; a transfer chamber to which the vacuum vessel is linked and through whose inside reduced in pressure the sample is transferred; a passage which establishes communication between the transfer chamber and the vacuum vessel in a state in which the transfer chamber and the processing chamber are linked to each other and through whose inside the sample not yet processed or already processed is transferred; and a covering member which is removably coupled to cover the internal wall face of the passage, wherein the sample is processed within the processing chamber with a plasma formed in the processing chamber.

In a vacuum processing apparatus having a plurality of vacuum processing chambers at least one of which are coupled to each of a plurality of vacuum transfer chambers which are behind an atmospheric transfer chamber and have vacuum transfer robots in their interior to transfer a wafer, taking out a plurality of wafers in a cassette and transferring successively to the plurality of the vacuum processing chambers, and thereafter returning to the cassette, the wafers are controlled to be transferred to all of the vacuum processing chambers coupled to the backmost vacuum transfer chamber and thereafter a next wafer is transferred to a vacuum processing chamber which becomes possible for the next wafer to be transferred in before they are possible to be transferred out from the vacuum processing chambers coupled to the backmost vacuum transfer chamber and arranged backmost.

The invention discloses a device for measuring the concentration of alcohol contained in the dampening water used in printing. Part of the dampening water pumped up from a dampening water tank (1) and delivered to a water fountain (3) is sampled through a bypass passage and the dampening water is returned to the dampening water tank (1) after the measurement of the concentration of the sampled dampening water. A measuring unit (8) for detecting the concentration of alcohol has a shielding plate (13) disposed adjacent to the dampening water inlet so that the disturbance of the surface of the dampening water introduced into the measuring unit is prevented. The dampening water discharge outlet consists of a pipe whose upper end is in coplanar relationship with a predetermined surface level of the aqueous solution in the measuring unit so that the excessive dampening water overflows into the pipe (10) to return to the dampening water tank. The measuring unit (8) includes a temperature sensor (15), a gas sensor (16) and a pH sensor (50) when required and the gas sensor (16) is disposed within a predetermined closed space.

An ink fountain has at least one position display means for displaying the position of each ductor blade piece to be preset before printing and at least one position indicating means for indicating an actual position of the blade piece. A gap between the distal end of the blade piece and the surface of an ink fountain roller is adjusted in such a manner that the actual position of the blade piece is registered with the position, to be preset, of the blade piece by operating an adjusting member.

A method for registering in an offset printing press comprises: mounting a printing plate on a shiftable table of a plate bending machine; detecting datum fine lines on said plate, by means of optical sensors; shifting the shiftable table so that said datum fine lines are placed at specific positions; inscribing, by means of a register mark inscribing device, register marks for carrying out automatic registering while, at the same time, bending the lateral edges of the printing plate; thereafter mounting the printing plate on a corresponding plate cylinder of a printing press; and carrying out automatic registering. The above plate bending machine comprises plate bending mechanisms, a shiftable table for holding the printing plate, optical detection sensors disposed above the shiftable table and operating to detect datum lines on the plate and thereby to generate signals for the movement of the table and register mark inscribing devices for automatic registering on a plate cylinder of the printing press.
摘要:
A method for forming or marking register marks used for the automatic registration between a plurality of printing plates in a printing press. A register mark forming or marking device is mounted on a printing frame of an automatic composer so that a register mark can be formed or marked on a printing plate simultaneously with the printing of a film original over the printing plate. Misalignment between the thus formed or marked register marks and patterns or images can be eliminated.

摘要:
An ink composition for heat transfer printing comprising at least one of carbinol bases of basic dyes or their derivatives, a strong base, a binder and a solvent for dissolving the binder. This ink composition is excellent in storage stability because it contains a carbinol base of a basic dye or its derivative in isolated form as a coloring agent along with a strong base. By using this ink composition, a transfer sheet having high storage stability can be obtained.
