Title: Test method for optical receiver
Inventor: TAKAI ATSUSHI
IPC: H04B10/07
Filed: 1992-10-08
Abstract: PURPOSE:To measure the waveform deterioration of a quenching level and an error rate characteristic and to apply the information processor of a DC coupling receiver by superimposing DC light on the input signal light of the optical receiver and conducting the test of the characteristic. CONSTITUTION:A DC coupling receiver can plot electric output for input light quantity. When a flip flop is built in, it can be plotted by adjusting a clock input level and providing control input. The emission and quenching of light are made to correspond to data. It is not essential to let quenching be a low level or a high level. It becomes the low level at a smaller quantity than a certain light quantity PIL and becomes the high level at a larger quantity than the light quantity PIL. An identification level exists intermediately. Thus, the quenching level can be set in a non-saturated or linear area (between PIL and PIH) of the input/output characteristic of the receiver by superimposing DC light, and the waveform of the quenching level can be observed. The quenching can be set around the identification level and an error rate can be measured in a short period time.

Abstract: PURPOSE:To improve a hydrophilic characteristic and reduce odor of silica when heat exchanging is carried out by a method wherein a particle diameter of silica particle contained in hydrophilic film is set in a specified range, silica particles more than a specified rate are made into spherical form and independent. CONSTITUTION:In the case that a particle diameter of silica particle is smaller than 0.2mum, silica particles may easily be discharged into surrounding air and silica odor is produced when a heat exchanger starts to be operated. In turn, when a particle diameter of the silica particle exceeds 0.8mum, discharging of silica particles into the surrounding air can be restricted and a total area of the silica particles is reduced. Accordingly, a particle diameter of the silica particle contained in the hydrophilic film is set to be 0.2 to 0.8mum. In addition, more than 50% of the silica particles are sphere in shape and are made independent from each other. With such an arrangement as above, the total area of the silica particles can be made sufficient and a superior hydrophilic characteristic can be attained, and silica odor when the heat exchanger is operated can be reduced.
