Title: Ink jet recording paper
Inventor: ITO YOSHIMASA
IPC: B41M5/50
Filed: 1989-04-13
Abstract: PURPOSE:To obtain ink jet recording paper capable of preventing the release of an ink receiving layer, excellent in writing properties or a paper quality feeling and not generating strike through by forming an ink receiving layer to a paper base material so as to divide the same into both parts applied to the front and rear surface thereof. CONSTITUTION:Ink jet recording paper 1 consists of a paper base material and the ink receiving layers 3, 3' formed to the front and rear surfaces of said base material. The ink receiving layers 3, 3' are formed from a composition prepared by adding a fine powder of an inorg. material such as silica, clay, talc, calcium carbonate, a calcium silicate, zinc oxide or magnesium carbonate to a polymer material such as polyvinyl alcohol, polyvinyl pyrrolidone or a vinyl pyrrolidone/vinyl acetate copolymer if necessary as a white filler. The ink receiving layers become thin and are not simply released even when stress such as bending is applied to the ink jet recording paper. Further, the paper quality feeling or writing properties of the paper base material is held by a degree of the reduction in the total thickness of the surface ink receiving layers. The ink receiving layer on the rear absorbs excessive ink without being accompanied by blur to prevent strike through.

Filed: 1990-04-09
Abstract: PURPOSE:To obtain the optimum gain and the optimum parameter of each compensation in order to secure the highly accurate and stable position control of a machine movable part at a high speed by showing the dynamic characteristic of the movable part in the form of a model of a spring mass system. CONSTITUTION:A storage part 5 samples and stores the velocity of a movable part, the acceleration of the movable part, and the motor current feedback value received from a velocity detector 106, an acceleration detecting part 4, and a current detector 104 respectively at the prescribed time. A calculation part 6 reads those velocity, acceleration and feedback value out of the part 5 and calculates the mass, the viscous frictional coefficient, and the Coulomb frictional force of the movable part. Then a storage part 7 stores these results of calculation obtained by the part 6. Thus it is possible to obtain the mass, the viscous frictional coefficient, and the Coulomn frictional force of the movable part which are necessary for attaining the highly accurate correction in a high speed machining state.

Title: Separating method for wafer and mask
Inventor: AIKO KENJI
IPC: H01L21/30
Filed: 1985-05-02
Abstract: PURPOSE:To separate a wafer from a mask without impairing the wafer, which is attached to the mask, by stopping a gas from small holes, communicating the small holes facing the peripheral parts of the wafer to a vacuum source, sucking the peripheral part of said wafer with vacuum, thereafter expanding the vacuum sucking region gradually toward the central part. CONSTITUTION:Opening valves 8e, 8f and 8d are sequentially opened. Then, the small holes, which perform vacuum sucking operation, are increased from the peripheral part to the center, in the sequence of the peripheral small holes 4e, the small holes 4g in the vicinity of the periphery, the small holes 4f in the vicinity of the center and the central small hole 4d. For example, when only the peripheral part of a mask 1 is sucked, atmospheric gas is inputted from the periphery to the part between the mask 1 and a wafer 2 as shown by arrows R. Thus the periphery of the mask 1 is separated from the wafer 2. Then, the periphery and the part in the vicinity of the periphery are sucked with the vacuum as shown by arrows Ve and Vg. Then the periphery and the part in the vicinity of the periphery of the wafer 1 are separated from the mask 2. When the vacuum sucking region is expanded to the vicinity of the center, the wafer 1 is separated from the mask 2 approximately entirely.

Title: Heat-conduction type cooling apparatus
Inventor: NAKANO RIKIZO
IPC: H05K7/20
Filed: 1989-04-12
Abstract: PURPOSE:To safely and easily execute an operation to separate a cooling structure body from a beating element by a method wherein a ventilation groove is provided on a face of the side coming into contact with the heating element of a beat-conduction part. CONSTITUTION:A plurality of ventilation grooves 1 whose one-end parts are situated nearly in the central part of a heating-element contact face 6 and whose other-end parts are set to an open state at their outer peripheral end faces 7a are provided on a face of the side facing a heating element 3 of a heat-conduction part 7, i.e., on the heating-element contact face 6. The ventilation grooves 1 guide the air at the outside to the central position of the heating- element contact face 6 even when a cooling structure body 5 and the heating element 3 are set to a state that they are brought into close contact with each other; accordingly, a vacuum state is hardly formed between the heat-conduction part 7 and the heating element 3. Thereby, when the cooling structure body 5 is separated from the heating element 3, the outside air invades from the ventilation grooves 1 and relaxes a vacuum constitution which is constituted between the cooling structure body 5 and the heating element 3; as a result, both can be separated safely and easily.
