An electron beam apparatus comprises an electron beam source, a unit for irradiating an electron beam on a specimen, a detector for secondary electrons, an electrode for generating an electric field sufficient to draw out secondary electrons in a recess in the specimen from the recess, and a unit for generating a magnetic field for focusing secondary electrons drawn out of the recess. With this construction, the secondary electrons drawn out of the recess by the electric field reach the detector without being attracted by the electrode. By adopting this construction, a contact hole of high aspect ratio formed in a semiconductor device and having a small diameter and a large depth can be observed.

Image processing conditions for scanning and processing an original by an electronic process scanner are set by an external image processing condition setting apparatus wherein a first system of coordinates is prepared in the scanner for processing, and a second system of coordinates is prepared in the image processing condition setting apparatus for position setting. An original cylinder is commonly used by both the scanner and apparatus, and by using a marked line formed on the surface of the cylinder as a reference position, both systems of coordinates are matched. A visual monitoring device which projects an image of a register mark onto the surface of the original cylinder is used in setting the image processing conditions. The visual monitoring device magnifies the image of the mark and a peripheral area of the surface of the cylinder, thereby enabling an operator to accurately locate a given position on the cylinder.

A cooling structure for a multi-cylinder piston-engine cylinder block includes a side coolant gallery distributing coolant into a water jacket surrounding a group of cylinders arranged from upstream to downstream. The flow cross-section of the coolant gallery decreases toward its downstream end. The water jacket has a water jacket wall which constitutes part of the coolant gallery. The water jacket wall includes a group of coolant inlets, each of which directs coolant towards the upper part of each of the cylinders. At least one coolant inlet is offset from the center of the corresponding cylinder toward a clearance between adjoining cylinders. This cooling structure can cool all of the cylinders uniformly and the entire surface of each cylinder evenly.

A display system includes an image forming device and a mobile communication terminal. In the display system, the mobile communication terminal accepts a flick manipulation to move the screen, and transmits flick information on the accepted flick manipulation to the image forming device. The image forming device decides an area, which is a part of the screen of the mobile communication terminal and in which display is changed when the screen is moving, and sequentially transmits to the mobile communication terminal positional information on the decided area and screen data of the screen before the movement is completed since the movement is started, which is decided based on the flick information in the decided area. The mobile communication terminal displays the screen in the area of the transmitted positional information based on the transmitted screen data.

A display system includes an image forming apparatus for storing screen data and a portable information terminal for displaying a screen based on the screen data stored by the image forming apparatus. The display system accepts flick operation for requesting movement of a screen at the portable communication terminal and transmits flick information concerning the flick operation to the image forming apparatus. The display system successively transmits screen data of screens from the start of movement to completion of movement from the image forming apparatus to the portable communication terminal, based on the flick information. The display system displays a screen based on the transmitted screen data on the portable communication terminal.

A job execution system comprises a job execution apparatus, a mode storage portion which stores mode control information that indicates the relationship between a user and a job execution mode of a group to which the user belongs, and a mode identification portion which identifies the job execution mode of the group to which the user belongs in accordance with the user information entered by the user and the mode control information. Furthermore, the job execution apparatus is equipped with a job execution portion which executes the job and a controller which allows the job execution portion to execute the job directed by the user for execution in a job execution mode identified by the mode identification portion.

A cathode ray tube is provided, in which the flatness of a tension mask constituting a color-selection mechanism is maintained by a suitable stretching force, while with the tension mask, the influence of external magnetic fields, such as the terrestrial magnetism is suppressed, and the shifting of the electron beam is reduced. A tension mask made of a magnetostrictive material is used, the tension mask is stretched by a stretching force in a range maintaining the flatness of the tension mask, and the direction and strength of the stretching force are set such that vertical magnetic permeability of the tension mask increases, due to a magnetoelastic effect caused by the stretching force in the magnetostrictive material of the tension mask.
