Title: Fluororesin member, process to make its surface hydrophilic, protection method against contamination and cleaning method
Inventor: WATABE TOSHIYA
IPC: B32B27/30
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain a fluororesin member capable of exhibiting a stable function to maintain hydrophilic properties and a protection against contamination for a long time by containing an optical semiconductor in the surface part, so that the surface of the semiconductor exhibits hydrophilicity and/or protection against contamination, when the surface is irradiated with a light of wavelength shorter than the excitation wavelength of the optical semiconductor. SOLUTION: This fluororesin member contains an optical semiconductor in the surface part, which exhibits a function to maintain hydrophilicity and/or a performance to protect against contamination, when the surface part receives the irradiation of light of wavelength shorter than the excitation wavelength of the optical semiconductor. Alternatively, the fluororesin member contains the optical semiconductor in the surface part, which is modified by irradiation of a light of shorter wavelength than the excitation wavelength of the optical semiconductor, so that the surface part generates the function to maintain hydrophilicity and/or the performance to protect against contamination.  The optical semiconductor is a substance which produces a conductive electron and positive hole pair by irradiation of a light having an energy of a larger width than the width of a band gap, and promotes a reaction directly or indirectly by the produced conducted electron or positive hole, for example, titanium oxide, zinc oxide or tin oxide can be mentioned.

Abstract: PURPOSE:To obtain the particle size of crystals in a nondestructive and contactless manner not only for a hot rolled steel plate, but for a cold rolled steel plate having a different texture from that of the hot rolled steel plate. CONSTITUTION:For each of three or more kinds of steel plates, the actually- measured particle size of crystals, an average of values corresponding to the coercive force detected by a measuring part 40, the size of the magnetic anisotropy detected by a magnetic anisotropy measuring part 50, and the magnetic permeability measured by a permeability measuring device 60 are input to a computer 70.

IPC: E01C5/04
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To improve strength and abrasion resistance and maintain water permeability for a long time of period for a landscape brick by making the sectional area of a through hole slit in the lower surface of a brick in contact with the surface of the earth 1.5 times or more greater than that of the brick at the surface of pavement. SOLUTION: In a landscape brick 1 provided in a street or a park, cross- shaped through hole slits 3 for imparting water permeability to the brick located within a distance of 10mm from the upper surface of the brick are formed into straight shape and other slits located below the straight slits are formed into tapered shape to form a brick of high density 2. And the sectional area of the slit 3 in the underside of the brick in contact with the surface of the earth is made 1.5 times or more greater than that of the brick at the surface of pavement.  As a result, rainwater is absorbed into the ground in a short time through the slits 3 and clogging of the slits 3 can be avoided and hence fine appearance of the brick is not injured and rainwater is allowed to naturally flow into the ground in a short time so that a landscape suitable for natural environment can be provided, strength and abrasion resistance can be improved, and water permeability can be maintained for a long time.

Title: Integrated circuit
Inventor: MUHLEMANN KURT
IPC: H01L27/02
Filed: 1993-03-15
Abstract: PURPOSE: To avoid damages due to a comparatively high load drive voltage, without using additional technology by limiting the drain voltage of a switching transistor through protection transistors. CONSTITUTION: A main part of this circuit is composed of a switching transistor T1 and protection transistors T2, T3, T4. When an input voltage is fed to an input terminal Vin , the transistor T1 turns on. A gate G2 is held at a fixed voltage VEE, the transistor T2 turns on, and transistors T3, T4 feed a drive output to a load terminal 01. An input terminal Vin changes to VDD, the transistor T1 turns on, and the transistor T2 turns off to lower the base of the transistor T3 to VEE. A source S2 of the protection transistor T2 lowers, and its source potential is held near VDD. This protects the drain and drain/gate of the transistor T1 from a breakdown.

Abstract: PURPOSE:To improve the ciphering efficiency by providing plural ciphering sections and selector switches, selecting a ciphering section corresponding to the length of a plain text so as to use the total sum of the ciphering sections as a ciphering output. CONSTITUTION:When a plain text is inputted sequentially to an input buffer 3 and a normal block length (e.g., 8-bit) is obtained in a block counter 2, the result is sent to a normal block length ciphering section 5 by a cipher selection switch 41.

Title: Electrophotographic sensitive body
Inventor: TANIGUCHI KIYOSHI
IPC: G03G5/047
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating higher fatty acid ester into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The higher fatty acid ester is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the higher fatty acid ester is chemically adsorbed in the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre- exposing fatigue are quickly recombined and are thereby annihilated, conceivably by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of the electrical charging and exposure is thereby obtd.
