Title: Regulator circuit
Inventor: NAGAI KENTARO
IPC: H01L27/04
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent destruction of external load equipment by suppressing abnormal rise of output voltage even when a power source input terminal to draw power source inside an IC from an output power line is opened. SOLUTION: Since output voltage of a transistor for output to output the voltage by dropping power source voltage is supplied to a feedback control circuit of the transistor Tr1 for output and a start-up circuit to start the transistor Tr1 for output through the power source input terminal VCC and the output voltage is independently supplied to the clamp circuit j through a power source input terminal for clamp, the output voltage is supplied from the power source input terminal for clamp to the clamp circuit j even when an accident that the power source input terminal VCC is opened. Thus, no output voltage of the transistor Tr1 for output rises abnormally by being clamped by the clamp circuit j and no external load is destroyed even when the accident occurs.

Abstract: PURPOSE: To stably perform electric discharge by converging emitted light corresponding to a secondary focal point or its vicinity on a rotary elliptical reflecting mirror and emitting light from a light emission passage selectively penetrating the wall of a cavity type oscillator. CONSTITUTION: A lighting device can be moved forward and backward to the axial direction of a cavity type oscillator 10 and a rotary elliptical reflecting mirror 11 by the operation of a support 14 supporting an eletrodeless discharge lamp 9. An area for an emission passage 12 for light which is emitted from the discharge lamp outside the cavity type oscillator 10 via the rotary elliptical reflecting mirror 11 has a small resistance with no gauzes, where light is easily converged. When a given high frequency electromagnetic field is supplied into the cavity type oscillator 10 for the lighting device via a coaxial cable 13 to excite the discharge lamp 9 for emission, 90% of emitted light is guided outside the cavity type oscillator 10.  The resistance is lowered by the change of the wall and the penetration in the light emission passage 12 area to increase the input of the discharge lamp 9 and the brightness of emitted light.

Abstract: PROBLEM TO BE SOLVED: To provide a microscope which is free of defocusing and can properly offset its focus position even when an observation is made with visible light by using an infrared light as the light source of an automatic focusing optical system. SOLUTION: The infrared light emitted by the light source 13 is made incident on an objective lens 2 and imaged on a body 24 to be detected. Reflected light from its surface to be detected 23 travels reverse along the optical path and passes through the objective lens 2 to impinge on a beam splitter 17. On optical detectors 18 and 19, split light spots 37 and 38 are formed respectively. Thus, the amplification factors of amplifiers 29, 30, 31 and 32 are varied to shift the position of a sample in one optical-axis direction where a focus error signal becomes 0. Namely, even when the infrared light is used as the light source of the automatic focusing optical system, the sample surface can be observed in an in-focus state with visible light.
