Title: Image pickup device
Inventor: KAWADA AKIO
IPC: H04N5/225
Filed: 1988-04-21
Abstract: PURPOSE:To prevent a video picture from being disturbed even when the voltage of a power superimposing signal line drops by substantially stopping the function of a switch lest the voltage of the power superimposing signal line drops even when the switch arranged on the side of a camera is operated after the camera power is superimposed on the power superimposing signal line. CONSTITUTION:When the switch SW is turned ON, the potential of the power superimposing signal line (l) is lowered, the call detection circuit 3 of a master unit (a) is operated, a power superimposing circuit 2 comes to an ON state and the camera power circuit 6 and the camera circuit 7 of a slave unit (b) operate through the power superimposing signal line (l). At that time, the voltage of the power superimposing signal line (l) becomes sufficiently higher than the voltage at the time of standing by. Thus, an impedance conversion circuit 8 makes the impedance between the power superimposing signal line (l) and the switch SW larger. Consequently, the change of the potential in the power superimposing signal line (l) can be considerably reduced even when the switch SW is depressed while the camera circuit 7 is operating, and the picture of a camera signal displayed on a display 7 will not been influenced.

Abstract: PURPOSE:To form an Si film on an SiO2 film, the Si film having satisfactory crystalline properties without being changed in its thickness depending upon an added impurity by effecting ion-implantation of silicon ion prior to ion- implantation of oxygen ion. CONSTITUTION:A silicon substrate 1 is ion-implanted with silicon ion Si<+> to form an Si<+> ion doped layer 6. The silicon ion Si<+> has a concentration peak of about 10<21>/cm<3> with a minimum value of about 10<18>/cm<3>. Then, the substrate is ion-implanted with oxygen ion O<+> over the ion-implanted layer 6 to form an O<+> ion-implanted layer 2c and Si<+> and O<+> ion-implanted layer 6c. Concentration distribution of the oxygen ion O<+> at that time is set such that it is 10<21>/cm<3> or higher. Hereby, the silicon ion implanted layer is made amorphous to permit the oxygen ion concentration distribution to be equal to a theoretical distribution. Further, any void in the silicon substrate at a silicon oxide interface is extinguished by excess silicon to assure a substantially ideal silicon oxide film interface.

Title: Method for testing ic testers in parallel
Inventor: ITOU KIYOSHI
IPC: G01R31/28
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase the number of parallel measurements per unit time by varying the test start waiting time of a test station in which the parallel measurements are set to match the stat of a handler. SOLUTION: When a test start request interrupt signal is sent from full- automatic conveying means (handler), the external equipment controller of an IC tester immediately executes the test of an IC in respective test stations. However, if the sending of the test start request interrupt signal is not from all the handles, the operating state of the handler which does not send the signal is read by the computer of the tester, and whether the interrupt can be sent within the waiting time set by the handler or not, i.e., whether it is effective waiting time or not is judged. If it is not effective, the test is immediately executed, while if it is effective, optimum waiting time is calculated and executes the tests at the time of lapse of the optimum waiting time.
