IPC: H04B10/032
Filed: 1986-10-08
Abstract: PURPOSE:To evade system-down even with a failed node in the titled network or with an opened drop cable by adopting the bus form. CONSTITUTION:An optical fiber between demultiplexers 30, that is, a trunk cable is broken, then the demultiplexer 30 connected to a node 14C has an open wire at a part of caption A.

Title: Variable forming type charged particle beam exposure apparatus
Inventor: SHIMIZU HIROYASU
IPC: H01L21/027
Filed: 1989-09-16
Abstract: PURPOSE:To enhance sensitivity of a deflector by forming a crossover image point through a first contraction lens between the centers of deflection of two deflectors. CONSTITUTION:A first contraction lens 4 forms a crossover image point 9 of a charged particle beam source 1 at a position of an aperture 16 arranged between a first subdeflector 8 and a second subdeflector 10, and contracts a formed image of a charged particle beam passing through the opening of a second forming aperture 12.

The deflection sensitivities of the deflectors 8, 10 are so adjusted that the deflection fulcrum of the deflector 10 becomes the point 9. The deflecting directions of the beam by the deflectors 8, 10 become the same since the point 9 is disposed between the deflectors 8 and 10. Accordingly, the centers of deflection of the deflectors 8, 10 can be matched to the point 9.

Title: Bus interface circuit
Inventor: AZEGAMI TADASHI
IPC: G06F13/40
Filed: 1991-09-20
Abstract: PURPOSE:To reduce burden on a bus and to enable multiple stations to be connected by providing an interface of level reacting type by using a pair transistor, and compressing the fluctuation of inlet current amount from the bus for the amplitude of a bus signal. CONSTITUTION:A series load element (pair transistor) 31 is inserted between each line of the bus 10 consisting of two line elements and an internal circuit 50. A parallel load element (resistor) 40 is connected between the two lines of the internal circuit 50. The interface of level reacting type can be realized by using the pair transistor 31, and the fluctuation of the inlet current amount from the bus 10 for the amplitude of the bus signal can be compressed, thereby, the inlet current can be suppressed. In such a way, the burden on the bus 10 can be reduced. Also, since current suppression capacity can be increased in the process where a signal waveform rises, signal delay can be reduced compared with the case using a resistor large in resistance simply. Also, the fluctuation of a receiving level for input can be suppressed, which stabilizes a load current.
