Title: Active/standby communication equipment
Inventor: HAMADA FUMIO
IPC: H04B1/74
Filed: 1988-09-30
Abstract: PURPOSE:To eliminate invaded noise in a section where signals inverted to each other are sent by sending a signal of either an active or a standby route while its polarity is being inverted, synthesizing signals of both the routes and extracting a noise component. CONSTITUTION:A signal inputted to an input terminal 1 is divided into two by a hybrid 2, the polarity of one signal only is inverted by a polarity inversion circuit 13 and an inverted signal is outputted from a terminal 3. Then signals inputted to terminals 7, 8 are branched respectively and they are inputted to a synthesizer 23. Since the signals inverted to each other are cancelled in the synthesizer 23, the signal level is much decreased and only the invaded noise progressed from cables 5, 6 is outputted. When the length of the cables 5, 6 is nearly the same and arranged in the same direction, since the invaded noise to the cables is of the same degree, the noise at the terminals 13, 14 is considerably decreased.

Title: Detecting apparatus for surface level of fused solder in solder bath
Inventor: KOBAYASHI SHIGEKI
IPC: B23K3/06
Filed: 1989-09-19
Abstract: PURPOSE:To detect the liquid level with high accuracy and to reduce labors for maintenance remarkably by sinking a sealed-type hollow body downwards in a solder bath which body is opened only at the lower end thereof and detecting the pressure within the hollow body by a pressure sensor. CONSTITUTION:A sealed-type hollow body 4 which is opened only at the lower end thereof is so arranged that the opening part of the hollow body 4 sinks within a solder bath 1. A diaphragm or semiconductor pressure sensor 6 is provided with the hollow body 4 to detect the pressure. Since the pressure of the hollow body 4 is changed in accordance with the liquid level of a molten solder 2, the liquid level can be detected from the pressure. When the liquid level is lowered, a motor 9 is rotated via a controller 7 to supply a solder rod 8. Therefore, it becomes unnecessary, in contrast to a conventional manner, to remove the oxide on the surface of the solder which causes deterioration of the detecting accuracy of the level, and labors for maintenance can be remarkably reduced.

Title: Spectroscope and light spectrum analyzer
Inventor: TACHIKAWA YOSHIHIKO
IPC: G01J3/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To obtain a spectroscope easy to realize a good resolution, downsizing and cost reduction by placing a phosphor in the front of an array element, and detecting a fluorescent light excited by long-wavelength light, using the array element. SOLUTION: A wavelength converter 110 composed of a phosphor is disposed in front of a photo detecting array element 15 and irradiated with a light dispersed through a wavelength dispersion element 13. The wavelength converter 110 has a part excited to emit a fluorescent light when this part is irradiated with a light to be measured. The array element 15 behind it detects the fluorescent light to measure the intensity of the light to be measured. If the phosphor of the wavelength converter 110 is formed only at a part corresponding to a photo element, the fluorescent light will not so spread as to be detected by adjacent elements on the array elements 15, thus easily improving the resolution.  If a phosphor film is formed on the surface of the array element 15 by the deposition, etc., the phosphor well adheres to the array element 15 to reduce a stray light due to sneaking of the fluorescent light.
