IPC: G02B7/32
Filed: 1982-05-13
Abstract: PURPOSE:To detect securely the low frequency component in the frequencies of modulation components by sampling and holding photoelectrically converted outputs once without detecting directly the modulation components contained therein and detecting the change rate of the signals at every sampling. CONSTITUTION:The distribution in the level of modulation components on the image-forming plane of respective image pickup elements 4, 8, 9 is such that the levels of the modulation components for the elements 8, 9 decrease at an equal rate with respect to the element 4 when the element 4 is in the stage of focusing and that the focus is matched at the element 4 when the values of the levels of the modulation components are equal. The outputs of the elements 8, 9 are supplied to sampling and holding circuits 12, 13, and are sampled and held. Since the photoelectrically converted outputs are once sampled and held, and the change rate of the signals at every sampling is detected, the low frequency component in the frequencies of the modulation components contained in the photoelectrically converted outputs is detected exactly.

Title: Information processing system
IPC: G01R31/00
Filed: 1992-04-02
Abstract: PURPOSE:To detect connection failure of a cable by inserting a resistor in series with the cable for connecting an equipment and transmitting a connection failure detection signal when the potential difference between both edges is within a reference potential range. CONSTITUTION:When a cable has connection failure and is disconnected, no current flows through a resistor 17 which is inserted in series with the cable. Therefore, the potentials at both ends of the resistor 17 are equal. At this time, even if the potential difference between both ends of the resistor 17 is amplified by an OP amplifier 21, only a potential which is lower than a positive reference potential +Vd which is input to a terminal 13 and is higher than a negative reference potential -Vd which is input to a terminal 14 can be obtained. When an output Vx is input to window comparators 22a and 22b, the outputs of the comparators 22a and 22b change to a high impedance state and a resistor 20 of a cable connection failure detection signal output terminal 15 changes to a high impedance state due to a pull-up resistor. On the other hand, when the cable is connected normally, the terminal 15 stays at the low level.

Title: Sewage treating device
Inventor: IZUMI SEIJI
IPC: C02F3/30
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To restrain the generation of nitrate nitrogen in a reaeration tank provided with a membrane separator in a sewage treating device in which sewage such as domestic waste water is introduced into a denitrification tank, a nitrification tank, a second denitrification tank and a reaeration tank in order to denitrify it. SOLUTION: A membrane separator 34 is separately installed inside a nitrification tank. A reaeration tank 24 has tank volume to house a membrane separator 35 for treating the quantity of sewage equivalent to the normal inflow. Since the tank volume of the reaeration tank 24 is smaller than before, the residence time in the reaeration tank 24 is shortened, allowing the generation of nitrate nitrogen due to endogenous respiration of denitrification bacteria or the like to be restrained.
