Title: Two-way optical repeater
Inventor: OOTSUKA TAKESHI
IPC: H04B10/29
Filed: 1983-07-21
Abstract: PURPOSE:To improve the reliablility as a repeater by transmitting signals of two-ways through an identical optical repeater in common. CONSTITUTION:Laser light irradiated from the optical repeater 7 is led to an optical branching filter 6 via an optical fiber line 13. The optical branching filter 6 branches optical signals of wavelengths lambda1 and lambda2, the optical signal having the wavelength lambda1 is outputted to an output terminal 2 via an optical fiber line 11 and the optical signal having the wavelength lambda2 is outputted to the output terminal 2 via an optical fiber line 10 respectively. Since the two-way signals are transmitted through the identical optical repeater in common in this way, no plural repeaters are required and since the multiplexing of the input light and the demultiplexing of the output wave are conducted by using an optical multiplexer and the optical demultiplexer serving as passive circuits, the reliability used as the optical repeater is improved.

Title: Method for evaluating latch-up withstanding capacity
Inventor: YASUOKA SEIJI
IPC: H01L21/66
Filed: 1992-05-26
Abstract: PURPOSE:To make it possible to evaluate latch-up withstanding capacity at an arbitrary point in the internal circuit of an IC chip by irradiating a parasitic bipolar transistor with ionizing radiation thereby turning the bipolar transistor ON. CONSTITUTION:The latch-up withstanding capacity evaluating system comprises an X-ray generating unit 14, a slit 15, an X-ray 16, a stage 17, and a chip 18 to be irradiated at an arbitrary point thereof with X-ray 16 through operation of the stage 17. When the chip 18 is irradiated with X-ray 16, electron-hole pairs are formed in a diffusion layer which absorbed energy during transmission process of X-ray 16. The electron-hole pairs produce potential difference in the diffusion layer and a parasitic bipolar transistor is turned ON to produce latch-up. This method can evaluate latch-up withstanding capacity at an arbitrary point on the chip 18.

Title: Fluid pipe
Inventor: KOSUGI ISAO
IPC: F16L55/04
Filed: 1980-09-27
Abstract: PURPOSE: To improve a freedom of selecting a pressure resisting pulsation damping resonance frequency by fixing a cylinder with its one end closed inside a power transmitting fluid pipe in such a manner that its open end is oriented toward the upper side of a fluid to trap a part of the fluid along with a gas in the cylinder.  
     CONSTITUTION: A gas trap accumulator 1 is formed in the shape of a cylinder 4 whose one end is closed and other end is opened as an inlet opening 3. The accumulator 1 is settled by fixing a flange member 7 with fluid openings 6 therein to the inner wall of a fluid pipe 2. When a pulsated fluid flows through the fluid pipe 2, the most runs from the inlet opening 3 into the cylinder 4 and the reset passes through the fluid openings 6 into the pipe 2. The fluid 4 inside the cylinder 4 compresses the air in a gas space 8. This compression and an inflow of the fluid make up a vibration system, thereby damping a pulsation. Such constitution as mentioned above may reduce a size and improve a pressure resistance and a freedom of selecting a damping resonance frequency on the basis of a choice of a length of the cylinder.
