Abstract: A vacuum processing chamber for measuring the temperature of a surface of an object comprising a cap is provided. The cap has a non-deformable end wall of thermally conducting material and a side wall connected thereto. An outside surface of the end wall is shaped to conform to a shape of the object surface to be measured. A surface on an inside of the end wall of the cap emits electromagnetic radiation having a detectable optical characteristic that is proportional to the temperature of the cap end wall. The vacuum processing chamber further comprises a light wave guide having one end held within the cap a distance from the radiation emitting element and in optical communication therewith.

Abstract: An error detector circuit compares a value corresponding to a laser power supplied from a monitor diode of an optical pickup with a value representative of a target laser power, and outputs an error from the target value to a change-over switch. The change-over switch selects one of low-pass filters used for CAV recording and CLV recording. The low-pass filter used for CAV recording has a larger time constant than that of the low-pass filter used for CLV recording. The servo gain of a servo loop during the CAV recording is therefore set smaller than that of a servo loop during the CLV recording. A change in the laser power becomes gentle.

Abstract: A temperature sensor that has a thermally conducting contact with a surface that emits electromagnetic radiation in proportion to the temperature of the contact is disclosed. The sensor has a resilient member attached to the contact and configured to extend the contact toward the object to be measured. A first light waveguide is attached to the contact and is configured to transmit the electromagnetic radiation from the contact. The sensor has a guide with a bore formed therein that the first waveguide is insertable into. When the contact is moved, the first waveguide moves within the bore. A second waveguide is attached to the guide such that a variable gap is formed between the ends of the first waveguide and the second waveguide. Electromagnetic energy from the first waveguide traverses the gap and can be transmitted by the second waveguide. The guide allows the first waveguide to move with the contact in order to ensure that the contact is fully engaged with the surface of the object.

Abstract: A temperature sensor utilizing optical temperature measuring techniques is constructed to make firm contact with a surface whose temperature is being measured, an example application being the monitoring of semiconductor wafers or flat panel displays while being processed. A cap is mounted near but spaced apart from an end of a lightwave guide, with a resilient element that applies force of the cap against a surface whose temperature is being measured as the cap is urged toward the optical fiber end. An optical temperature sensing element, such as luminescent material or a surface of known emissivity, is carried within the cap. A bellows with a closed end conveniently serves as both the cap and the resilient element. An alternative temperature measuring device installs an optical temperature sensing material within a test substrate behind an optical window, and then views the sensing material through the window.

Abstract: An image pickup apparatus capable of reducing influence of flicker while suppressing delay of start of photographing. An image pickup device and a photometric sensor pick up images of an object. A CPU obtains images by controlling driving of one of the device and the sensor to perform charge accumulation and charge readout. Further, the CPU detects a flicker frequency and a flicker phase of a flicker light source, and stores them in a memory as first information. When photographing, if the CPU determines that the first information is not valid, an ICPU obtains images by controlling driving of the other of them to perform charge accumulation and charge readout. Further, the ICPU detects the flicker frequency and the flicker phase and stores them in a memory as second information. The CPU controls exposure timing according to the second information to perform photographing.
