Filed: 1994-05-20
Abstract: PURPOSE:To enable signal transmission without any reflection and attenuation even through a transmission line provided with unspecified impedance by constituting a transmission system provided with an emitter grounded circuit on the signal transmission side and a base grounded circuit on the signal reception side, or provided with the circuits vice versa. CONSTITUTION:The circuit is constituted of an emitter grounded type transistor output circuit (TR1) for inputting signals Vi to a base and taking out the signals from a collector, a wired transmission line 1 for transmitting the output signals of the collector in the output circuit and a base grounded type input circuit (TR2) for inputting the signals to the base through the transmission line 1 and taking out the signals from the collector. Thus, when the current amplification factor of the emitter grounded transistor TR1 is defined as beta and a base current is defined as Ib, a constant current source loop by the beta and Ib is constituted between a signal output side circuit and a signal input side circuit. Thus, the signal transmission by a current is made possible even when the impedance of the transmission line 1 changes and an input voltage Vi and an output voltage Vo become unrelated to the impedance of the transmission line 1.

Title: Color fluorescent light emitting tube
Inventor: FUKUDA TATSUO
IPC: H01J63/06
Filed: 1984-05-28
Abstract: PURPOSE:To prevent occurence of electric discharge even if high speed electron beam is used, by placing a shield plate between the negative electrode filament and the side plate. CONSTITUTION:A shield plate 38 is placed between a negative electrode filament 22, a control grid 23, a screen grid 28 and a side plate 17, so as to screen the side walls of the formers from the latter. The high speed electron beam released from the negative electrode filament 22 is controlled by a control grid 23 and uniformly collides with the light emitting cells 12 to make the light emitting cells emit light. During this time, a part of released electrons heads towards the side plate 17 from the filament 22, control grid 23 and side of screen grid 28. However, it is shielded by the shield plate 38, and thus does not collide with the side plate 17. As a result, the generation of electric discharge between the negative electrode filament and the side plate can be prevented. As the shield plate 38 is an electrically conducting material and is maintained at the same potential as the screen grid 28, electric discharge between the shield plate and the negative electrode filament is never generated.

Title: Photographing device for transmission electron microscope
Inventor: WATABE AKIRA
IPC: H01J37/22
Filed: 1994-05-23
Abstract: PURPOSE:To detect the existence of a film at the photographing position, and to securely control the number of film in a vacuum discharged photographing device by forming a cassette for holding a film as a part of a detecting circuit. CONSTITUTION:A cassette 3 for holding a film 2 is made of the conductive material, and an electrical insulating spacer 5 is fixed between two terminals (a base plate 4 and a plate spring 6) positioned at the photographing position. In the case where the cassette is positioned at the photographing position, the electrical resistance between the terminals is formed into a short-circuit, and in the case where the cassette is not positioned at the photographing position, the electrical resistance between the terminals becomes the infinity. This change is detected by CPU 10, which controls the photographing mechanism, through an interface 9, and the condition that the cassette 3 is set at the photographing position or not is displayed in a CRT 11. Consequently, existence of the cassette at the photographing position can be detected without using a detecting element, and an artificial error at the time of inputting the number of film in the CPU can be compensated, and the secure control of the number of film is enabled.
