The stroke of the slider 3 is regulated by the position of the moving block 12. The advancing position of the moving block 12 is controlled by the drive motor 16 to regulate the pressure and the stroke of the slider 3. The pressure of the slider is reduced by appropriately selecting a reduction spring built in a press rod 2 of the slider 3.
Patent JP-S6394693-A (JP)
Title: Semiconductor device
Inventor: ONO YASUO
IPC: H01L47/02
Filed: 1986-10-08
Abstract: PURPOSE:To obtain simple structure and to enable various logic operations in which a high electric field domain is used by a signal from controlling terminals, by forming terminals to which an electric field is applied so that a product of carrier concentration and region's length measured in the carrier traveling direction is specified for Gunn oscillatory conditions so as to be above critical electric field strength Ec for the first and third regions and be below the Ec for the second region. CONSTITUTION:Carrier concentration and length are made 10<15> cm<3> and 8 mum, respectively, on the first regions 1 to 4 and the third region 5 of a sample made of GaAs. Therefore, a nL product becomes 0.8X10<12>cm<2> and so Gunn oscillation does not occur even if a high electric field is applied. When voltage is applied to both end terminals 20A and 20B of the GaAs sample so that potential difference between each of 2A regions 7, 8 and the third region 9 becomes 10 V, electric field strength in the first regions 3 and 4 becomes above the critical one Ec, but Gunn oscillation does not occur because the nL product is insufficient. When a high electric domain is transferred from the first region 1 to the first region 3 and rushed to the second region 9, a logic operation AND or OR is performed by gate biasing.

Filed: 1988-09-28
Abstract: PURPOSE:To shorten a time for measurement by heating a substrate, by measuring the intensity of an infrared energy radiated from the surface of the resist of the substrate and by converting a measured value into the film thickness of the resist. CONSTITUTION:Infrared rays emitted from the surface of a resist 2 when a substrate 1 is heated by a plate heater 10 are condensed by a condenser lens 13, reflected by a reflector 14 and projected on an infrared detector 15. By rotating the mirror 14 repeatedly in this constitution, the intensity of an infrared energy in the whole area of the surface of the resist 2 can be measured. An information on the intensity of the infrared energy detected by said detector 15 is inputted to an image processing device 16, the two-dimensional distribution of the intensity of the infrared energy is analyzed, and the result of the analysis is displayed in CRT 17. On the occasion, the intensity of the infrared energy radiated from the surface is larger in the part of large film thickness of the resist 2 than in the part of small thickness thereof. By determining the relationship between the intensity of the infrared energy and the film thickness of the resist beforehand, accordingly, the distribution of the film thickness of the resist can be determined.

Title: Optical disc inspecting instrument
Inventor: UEKI KAZUNORI
IPC: G11B7/004
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To enable detection of both of obstacles, one which decreases the quantity of reflected light and the other which increases it over the entire recording area in the diametrical direction of an optical disc. SOLUTION: An optical head 4 is displaced over the entire recording area in the diametrical direction of an optical disc during the inspection of the optical disc. The obstacle of the optical disc is judged by a disc obstacle judging means 22 even when a detection output from a quantity of reflected light detection circuit 9 is deviated, low or high, from a normal level range that enables the judging of the optical disc to be normal. As a result, both obstacles, one which decreases the quantity of reflected light and the other which increases it, are detected over the entire recording area of the optical disc. In this case, the location of the obstacle judged to obstruct is detected using a detection output from a displacement value detection circuit 12, thereby enabling learning of the position of a disc where the obstacle location exists.

Abstract: PURPOSE:To enable a high precision alignment by separating two light beams having slightly different frequencies and planes of polarization perpendicular to each other, and extracting optical beat signals through the same light path without irradiation onto a diffraction grating, thereby separating the diffracted light beams to obtain stable beat signals. CONSTITUTION:By a telecentric lens 10, the + primary diffracted light of the diffracted light beams from a reference grating 12 is intercepted, and only the primary and zero diffracted light beams are transmitted. For this reason, the + primary diffracted light of a zero diffracted light 3 by a diffraction grating 3 is diffracted as a + primary diffracted light 3', and similarly, the -secondary diffracted light of the - primary diffracted light from the reference grating 12 by the diffraction grating 15 is incident upon a detector 25 as a - secondary diffracted light 2' through the same light path. And from a second photodetector 26, an optical beat signal also containing a positional shift  X of a wafer with respect to the reference grating is obtained, and a mask stage 19 or a wafer stage 20 is slightly moved so that the phase difference between these two optical beat signals becomes zero. With this, the relative alignment of the photomask and the wafer can be performed.
