Title: Hot melt adhesive
Inventor: TAKAHASHI YOSHIKO
IPC: C09J167/00
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To achieve adhesion which is highly resistant to dry cleaning, by compounding a polyester-urethane copolymer resin with a styrene-maleic acid copolymer so as for the resultant mixture to have a specific melt viscosity. SOLUTION: This adhesive is prepared by compounding a solution of a polyester-urethane copolymer resin, which has a saturated thermoplastic polyester as its main chain and a urethane as a side chain, in a methyl ethyl ketone/ toluene mixed solvent at a concentration of 20 to 40wt.% with 5 to 15wt.% of a tackifier such as a styrene-maleic acid copolymer. The adhesive has a melt viscosity at 125 deg.C of 400 to 600Pa.s and exhibits a tensile elongation at room temperature of 1,200% or more. The adhesive having such a melt viscosity can seep into textures of a water-repellent base cloth and an uneven surface of a body to be adhered, and by using the adhesive an adhesive thickness of 40 to 80μm which is necessary for effective adhesion can be ensured.  Due to the softness and a large tensile elongation of this adhesive, stress relaxation takes place at the interface between an adhesive and a body to be adhered in peeling, which results in great adhesiveness.

Title: Method and apparatus for inspecting defect
Inventor: SHIGYO YOSHIHARU
IPC: G01N21/956
Filed: 1992-02-04
Abstract: PURPOSE:To keep defect detection sensitivity constant regardless of the lowering of the output of an inspection light irradiation device. CONSTITUTION:In a defect inspecting method wherein a wafer 1 is irradiated with inspection light 21 by an inspection light irradiation device 20 and the scattered light 31 of the inspection light of the wafer is detected by a scattered light detector 34 to inspect a defect, the initial output value of the inspection light 21 applied from the inspection light irradiation device 20 at the beginning is preliminarily measured and the output value of the device 20 is measured periodically and non-periodically. This measured value is compared with the initial output value and, when the measured output value is judged to be deteriorated with respect to the initial output value, correction control is applied to the inspection light irradiation device 20 so that the measured output value becomes equal to the initial output value corresponding to a deteriorated quantity value. Since the detection sensitivity of the scattered light detector 34 is held to the initial detection sensitivity by increasing the output value of the device 20, the detection sensitivity of the detector 34 can be kept constant regardless of the deterioration of the device 20 with the elapse of time.

IPC: H04N5/14
Filed: 1978-05-08
Abstract: PURPOSE: To secure an automatic correction for the resolution change of the video signal which is visible remarkably at a large-size picture receiver when receiving the signals which passed through the transmission systems of different transmission distotion properties or received different transmissiin distortions, and thus to ensure nearly the uniform resolution for the TV picture receiver.  
     CONSTITUTION: The amplitude of the burst signal is extremely small in comparison with the amplitude of the horizontal and vertical synchronous signals in the composite signal in the case of the TV signals which passed through the transmission system of a large transmission distortion, that is, in the case of the picture the resolution of which is deteriorated greatly. While it is noticed that the amplitude of the burst signal increases greatly in the case of the TV signals rceived via the transmission system of a small transmission distortion, that is, in case the picture of a high resoultion can be reproduced. In this respect, amplitude comparator 4 is constituted with the differential amplifier, and the output of horizontal synchronous isolation circuit 11 and burst sampling circuit 12 are applied to each base of a pair of transistors forming circuit 4. Thus, the DC output proportional to the difference of the amplitude of both signals can be obtained to be then applied to frequency property variable circuit 3 as the control signals.
