IPC: H04B10/572
Filed: 1989-12-29
Abstract: PURPOSE:To make it possible to switch and completely set the oscillation frequency of a laser device by injecting all of a plurality of prefixed rays of light into the optical resonant path of the laser device and changing the oscillation frequency in accordance with control signals. CONSTITUTION:The oscillation frequencies of semiconductor lasers (LD) 1a, 1b, 1c, and 1d are set so that the frequencies can coincide with the value at which the oscillation frequency of an LD 6 must be set while the frequency changes with time. An electric current is made to flow to the phase controlling area 6b and Bragg reflection area 6c of the LD 6 by a drive circuit 8 in accordance with a control signal from a controller 9. In this case, the areas 6b and 6c are driven by one power source by utilizing a resistive divider. In addition, the electric current which is made to flow to the activated area 6a of the LD 6 is maintained at a fixed level. Thus rays of light having an oscillation frequency to be prefixed are injected to the LD 6 and the oscillation frequency of the LD 6 can be switched and completely set, because the oscillation frequency is automatically changed to a set value due to an injection synchronizing phenomenon.

Title: Fault analyzing method for semiconductor memory device
Inventor: ITO HIDEKI
IPC: H01L27/108
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To quickly and easily analyze a fault of a semiconductor memory device by detecting the difference in potential change amount of a word line generated when the potential of a cell plate is changed, on the basis of a coupling capacity of the cell plate and word line. SOLUTION: A parasitic capacity Cwp is generally present between a word line WL and a cell plate Cp. When a memory node and the word line WL are shortcircuited at a resistor R, a coupling capacity between the word line WP and cell plate Cp is increased to Cwp+Cs. Therefore, a potential change amount ΔVw1 of the word line when a cell plate potential Vcp is changed is normally equal to ΔVcp*Cwp/(Cw+Cwp). On the other hand, at the shortcircuited line, ΔVw1=ΔVcp*(Cwp+Cs)/(Cs+Cwp) is held. The presence/ absence of a shortcircuit at the word line can be simply detected from the difference of the potential change amounts.
