Abstract: PURPOSE:To make an abnormality detector adaptable on a phase control noncontact contactor wherein the throw-in phase of switching element is controlled by constituting the abnormality detector of a pulse generating circuit, an OR circuit for providing output to a firing circuit, and a circuit for deciding the abnormality in a main switching circuit and outputting a detection signal. CONSTITUTION:A phase control circuit IC produces an output pulse 2 having relatively narrow width To at the position of phase control angle alpha every half period T1 of power supply waveform. On the contrary, a pulse generating circuit 9 produces an output pulse having period T3 and width T2 larger than those of the output pulse from the phase control circuit IC. Preferably, T3 is several to ten or thereabout seconds and T2 is 20 to 50mS. An OR circuit 10 delivers logical sum of output pulses from the phase control circuit and the pulse generating circuit 9, as an operational input, to a firing circuit 1B. A decision circuit 4 then makes a decision of abnormality based on an output voltage from an abnormality detector rectified through a three-phase full-wave rectifying circuit 3 and an output pulse from the OR circuit 10.

Title: Focus detector
Inventor: KUSAKA YOSUKE
IPC: G03B13/36
Filed: 1995-09-11
Abstract: PURPOSE: To detect even the focus of an object incapable of detection by a conventional device by detecting the focus based on added data information obtained by the addition data processing means for adding the data information of a subject plural number of times. CONSTITUTION: The focus of a general object is detectable at the time when a loop counter indicates one (at the first time) since third-order data include many contrast changing components and an addition mode does not occur. The third-order data of a low contrast object have few contrast changing component when the loop counter K indicates one, detection is incapable at the first time and the addition mode occurs again. The third order data are amplified every time the addition mode is repeated and at the Sth times e.g. they are amplified S-times of the data at the first time. When the third-order data are amplified in the addition mode, the detectable level of focusing appears at some numbers of times, as the result of focus detecting arithmetic, the capability of detection is decided and the operation is slipped out of the addition mode.
