The present invention provides an electron beam apparatus for irradiating a sample with primary electron beams to detect secondary electron beams generated from a surface of the sample by the irradiation for evaluating the sample surface. In the electron beam apparatus, an electron gun has a cathode for emitting primary electron beams. The cathode includes a plurality of emitters for emitting primary electron beams, arranged apart from one another on a circle centered at an optical axis of a primary electro-optical system. The plurality of emitters are arranged such that when the plurality of emitters are projected onto a straight line parallel with a direction in which the primary electron beams are scanned, resulting points on the straight line are spaced at equal intervals.

In addition to an FM reception antenna element for receiving an FM radio wave and an FM receiver connected to the FM reception antenna element, a mobile object is provided with a first antenna element for receiving a satellite signal, a signal processing unit connected to the first antenna, and a second antenna element connected to the signal processing unit. The signal processing unit processes the satellite signal into an FM signal. The second antenna element emits the FM signal as the FM radio wave that may be received in the FM reception antenna and processed by the FM receiver in the manner known in the art.

A method of machining a cathode used in an electron gun. The method includes steps of placing an object to be machined, which is a material of the cathode, and a machining electrode in an electrically insulating oil; applying a discharge current to the machining electrode; and machining the object to be machined to have a shape corresponding to the shape of the machining electrode by means of electric discharge machining of the machining electrode. The machining electrode includes a disk, recesses formed on a front surface of the disk, a protrusion provided on a back surface of the disk, and a hole for mounting a lead wire for applying discharge current to the machining electrode. Bumps corresponding to the shape of the recesses of the machining electrode are formed on the object to be machined by means of the electric discharge machining.

A personal computer connected to a USB port of a printer through a management table managing writing on an ordinary storage region in FLASH ROM recognizes the ordinary storage region in the FLASH ROM of the printer as a removable drive which is a USB mass storage class device. Accordingly, an execution file of an application program stored in a portion of the ordinary storage region in the FLASH ROM can be read with a usual access from the personal computer, enabling the application program to be executed without being installed. When the application program is executed on the personal computer, periodic accesses are made to the ordinary storage region of the printer, and when an access fails, the application program is terminated.

A hinge portion is formed on the base portion. An antenna portion is attached to the hinge portion so as to be pivotable thereabout. The hinge portion includes a hinge base having a first shaft formed on one end thereof, a second shaft formed on the other end thereof, and a first protrusion formed on an outer periphery of the second shaft, and a hinge bush rotatably mounted on the first shaft and engaged with the antenna portion. The antenna portion is formed with a hole surrounding the outer periphery of the second shaft. A projection is formed on an inner periphery of the hole. The first protrusion is brought into contact with the projection when the antenna portion is pivoted so as to define a predetermined angle with respect to the base portion.
