Filed: 1987-10-07
Abstract: PURPOSE:To obviate generation of low-temp. air bubbles and to obtain a uniform cell thickness at a high degree by incorporating rigid particulate matter and specific polymer particles as a spacing member in a liquid crystal. CONSTITUTION:The rigid particulate matter 4 and the polymer particles 5 having at least 10-30wt.% epoxy group are incorporated as the spacer into the liquid crystal 2. Namely, the particles 4 having high rigidity limit the min. value of an inter-substrate spacing in a stage for sticking two sheets of substrates 1, 1. The polymer particles 5 are deformed by the pressure and heating in said stage to the thickness (d) determined by the particles 4 having the high rigidity and are thereby adhered to the substrates 1, 1. The polymer particles 5 maintain the thermally deformed flat shape when the substrates are cooled down to ordinary temp. upon ending of the sticking stage. The liquid crystal 2 is sealed into such cell and an injection port is sealed. The uniform cell thickness distribution is thereby shown in the display plane and the generation of the low-temp. an bubbles is substantially obviated.

IPC: G01S15/96
Filed: 1987-10-08
Abstract: PURPOSE:To use the dynamic range of an amplifier which amplifies a received signal from a transmitter receiver effectively to a reflected wave from a school of fish by detecting the saturation level of a fish school amplifier. CONSTITUTION:A saturation detection part 13 detects the saturation of the fish school amplifier 11 when the amplifier 11 is saturated to a signal indicating the reflected wave from the school of fish. Further, saturation is detected to a signal indicating a reflected wave from the bottom of the sea and a saturation detection signal 131 is outputted. A sea bottom amplifier 12 has its amplification factor set low so as not to get saturated to a signal indicating the school of fish. Further, a sea bottom detection part 14 has its detection level set preliminarily so as to output a sea bottom detection signal 141 when the sea bottom amplifier 12 outputs a signal higher in level than the signal indicating the school of fish, namely, when a signal indicating the bottom of the sea is led. Therefore, when the bottom is detected, the signal 131 is outputted and then a signal 141 is outputted with slight time delay. Then a warning signal generation part 9 generates a warning signal 171 unless the signal 141 is detected even after a specific time after the signal 131 is inputted.
