Title: Radio frequency amplifier
Inventor: SCOTT MUNRO
IPC: H04B1/04
Filed: 2001-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a new improved radio frequency(RF) amplifier especially suitable for a cellular telephone. SOLUTION: This amplifier is provided with a resonance circuit feedback circuit composed of a capacitor 22 and an inductor 24 serially connected between an input terminal 20b and an output terminal 20a of a semiconductor device 20.

Title: Device for focusing and applying electron beam in atmosphere
Inventor: ETO KIICHI
IPC: G21K5/04
Filed: 2001-02-16
Abstract: PROBLEM TO BE SOLVED: To resolve the problem that the probability of irradiation is lessened and a device is larger because an electron beam scatters on an electron beam transmissive bulkhead as an anode if an electron beam generated in a vacuum is extracted from it and is applied in the atmosphere, particularly when a small object to be irradiated or a thin linear material is irradiated with the electron beam of a large volume, and prevent the life of the bulkhead from shortening due to the load on the electron beam transmissive bulkhead when the acceleration dose of the electron beam is increased. SOLUTION: An outside anode 5 is located in a rear position of a sample 1 to be irradiated to focus electrons 1 scattered by the electron beam transmissive bulkhead 4 toward the outside anode 5. The electron beam passes through the sample 1 to be irradiated and flows into an outside electrode by locating the sample 1 to be irradiated between the electron beam transmissive bulkhead 4 and the outside anode 5, so that the efficiency in electron beam irradiation can be improved. If the sample 1 is a thin linear material, it is irradiated with the electron beam from the circumferential direction, and the electron beam is applied efficiently and uniformly by revolving an acicular outside anode on the outer periphery of the linear sample around it.
