摘要:
A polishing apparatus includes a holder for holding a polished body with a polished surface thereof facing upwardly, and a polishing head for holding a polishing pad having a polishing surface having an area smaller than an area of the polished surface while contacting the polishing pad with the polished surface and for rotating the polishing pad around its rotation axis. The polishing head is provided with a driver for revolving the polishing pad around a revolution axis, and the revolution axis and the rotation axis are positioned so that a distance between the revolution axis and the rotation axis becomes smaller than a radius of the polishing pad.

A polishing apparatus that can effectively and efficiently remove potassium and other alkaline metals comprises integrally a polishing unit for polishing an object by means of a polishing agent and a cleaning unit for cleaning the polished object. The polishing unit and the cleaning unit have means for isolating the internal atmosphere from the external atmosphere and the cleaning unit has a means for cleaning the polished object by bringing hot pure water or steam of pure water into contact with the polished object. With a cleaning method hot pure water is brought into contact with the polished object without drying it after having been polished by such a polishing apparatus.

Provided is a connecting part for a semiconductor device including a semiconductor element, a frame, and a connecting part which connects the semiconductor element and the frame to each other, in which an interface between the connecting part and the semiconductor element and an interface between the connecting part and the frame respectively have the area of Al oxide film which is more than 0% and less than 5% of entire area of the respective interfaces. The connecting part has an Al-based layer and first and second Zn-based layers on main surfaces of the Al-based layer, a thickness ratio of the Al-based layer relative to the Zn-based layers being less than 0.59.
摘要:
An image processing apparatus provided with a display unit for displaying an operation picture, showing control indicia (e.g., icons) corresponding to multiple image processing functions, is operated to display the operation picture on an external display device. The operator selects one of the indicia shown on the external display device by operating an input device, such as touch screen of the apparatus or a remote control, to indicate the position of the desired one of the indicia. The operator can thereby quickly and reliably select an image processing function to be executed, without any need to view an operation picture on the display unit when making the selection.

A cutter machine has a knife holder 13 mounted onto a cutter shaft 6 at the center portion, wherein a material to be cut is cut with knives 15 mounted onto the outer circumference of the knife holder 13 by rotating the knife holder 13 around the cutter shaft 6. The knife holder 13 is separated into a fixing member 17 mounted onto the cutter shaft 6 and a mounting member 18 onto which the knives 15 are mounted. The mounting member 18 is pivotally supported around two axes with respect to the fixing member 17. In the cutter machine, the knives and a die plate come into contact with each other by a small press force of the knives, thereby enabling a satisfactory cutting to be obtained.

A dynamic image recording button and a still image recording button are provided at the main unit of a movie camera. A magneto-optical recording medium is loaded in a slot. If the dynamic image recording button or the still image recording button is operated during a reproduction operation, the reproduction operation is interrupted in a state in which the mechanical drive (rotation) of the magneto-optical recording medium is sustained. At this point, a dynamic image signal or a still image signal obtained through a photographing operation performed at the camera unit is temporarily recorded in a buffer memory, and is written in the magneto-optical recording medium when a write in the magneto-optical recording medium becomes enabled. Instructions to record dynamic images and to record still images can be issued to the movie camera through a touch-panel provided on the screen of a liquid crystal display unit. Even when operation cannot be performed through the touch-panel, the instructions can be issued through the dynamic image recording button or the still image recording button.
