Title: Synchronous semiconductor storage device
Inventor: KODAMA YUKINORI
IPC: G06F1/04
Filed: 1994-03-07
Abstract: PURPOSE:To allow a data transfer destination to input correct data by supplying a constant voltage having a specified voltage as a power source voltage to a clock input circuit. CONSTITUTION:A clock input circuit 23 takes in a system clock signal CLK supplied from outside and outputs an internal clock INTCLK after performing the waveform-shaping of the signal. Data DQ are outputted by being delayed by an access time from the signal CLK and a constant voltage VII having a voltage suppressing the change of the operating speed of transistors Trs with respect to the change in temperature is supplied to the circuit 23. Further, since the voltage VII is also supplied to a data output circuit 27, the change of the delay time in the circuit 27 due to variations in power source voltage VCC from the outside and the change in temperature can be suppressed. Thus, correct data can be inputted in the data transfer destination because the change of the access time from the signal CLK due to variations in the voltage VCC and the change in temperature can be suppressed.

IPC: H01S5/068
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To enable laser beams outputted from a laser diode to be restrained from being modulated in intensity when the laser diode is subjected to frequency modulation. SOLUTION: An adder 12 is made to add a light frequency modulation signal Sm to a direct-current voltage which enables a laser diode 10 to continuously oscillate laser beams to drive the laser diode 10. Laser beams outputted from the laser diode 10 are inputted into a light intensity controller 14. The light frequency modulation signal Sm is regulated in phase and amplitude by a phase control circuit 16 and an amplitude control circuit 18 and then applied as a control signal to the light intensity controller 14. The light intensity controller 14 serves, for instance, as an electric field absorption light modulator and is varied in transmittivity corresponding to the voltage output of the control circuit 18.  The circuits 16 and 18 are so set in adjustment value as to enable a variation in the transmittivity of the light intensity controller 14 to restrain the light output of the laser diode 10 from being varied in intensity.

Title: Mosfet with input protection circuit
Inventor: YOKOSUKA AKIYASU
IPC: H01L29/08
Filed: 1989-02-15
Abstract: PURPOSE:To keep gate voltage to be constantly lower than gate oxide film breakdown voltage for preventing gate breakdown by forming emitter/collector and diode of a horizontal type transistor at a demarcated region of epitaxial layer as a gate voltage limiting diode. CONSTITUTION:An n<-> type epitaxial layer 10 is set to the demarcated region by a p<+> type isolation 3 and a p<+> type emitter region 11 produced by excluding the base region diffusion process of a horizontal PNP transistor as well as a p<+> type collector region 12 surrounding it are formed within the demarcated region 10. Then, both regions 11 and 12 operate as the cathode and anode regions of each gate voltage limiting diode. Thus, since the base-open horizontal type PNP transistor is formed within the n<-> type epitaxial layer 10 as a voltage limiting diode, the collector/emitter withstand voltage is lower than the gate oxide film breakdown voltage. Thus, it is possible to keep gate voltage to be constantly lower than the breakdown voltage, thus preventing gate breakdown.
