Title: Method for controlling target coercive force of magnetic film
Inventor: SATO MOTOHARU
IPC: H01F41/24
Filed: 1986-11-07
Abstract: PURPOSE:To form Co-Ni-P magnetic films having different coercive forces by a method wherein, while the concentration of each component except metal ions is kept constant, the molar ratio of cobalt ions and nickel ions is changed with the total concentration thereof kept constant. CONSTITUTION:In obtaining a Co-Ni-P magnetic film by an electroless plating using a aqueous solution containing cobalt ions and nickel ions as well as complexing agent of these metal ions and containing diphosphite as a reducing agent, while the concentration of each component except the metal ions is kept constant, the molar ratio of the cobalt ions and nickel ions is changed while the total concentration thereof is made constant, thereby forming the Co-Ni-P magnetic films which are different in coercive force. That is, the target coercive force of a Co-Ni-P magnetic film can be controlled without affecting other magnetic characteristics, and since the residual magnetic flux density is not varied so much, the control becomes accurate, which can fully respond to the demand for a high-density recording.

Filed: 1989-10-13
Abstract: PURPOSE:To eliminate the need for the synchronization of the clock of each controller installed decentralizingly and the clock of a database equipment by informing current time information of the clock possessed by the controller to the database equipment and collecting the information with time pattern information possessed by the database equipment. CONSTITUTION:When a current time of a controller 11a is collated with time pattern information in a database equipment 14, the controller 11a reads its own clock 12a to obtain current time information. The controller 11a informs the current time information read with a collation request to the database equipment 14 via a communication line 13a. Then the database equipment 14 uses the current time information informed from the controller 11a and collates it with time pattern information 16 of the database equipment 14. Moreover, the result of collation is informed to the controller 11a via the communication line 13a. Thus, it is not required to completely synchronize the clock of the controllers installed decentralizingly with the clock of the database equipment.

Title: Surface processed coated paper cloth
Inventor: SUNAMI SHOJIRO
IPC: B29K101/10
Filed: 1990-10-04
Abstract: PURPOSE:To reduce the irregularity of pressure distribution in a heating and pressing state at the time of pressing and to prevent sliding when a resin begins to flow by bringing a base material impregnated with a thermosetting resin to a semicured state by drying and passing the semicured base material through rolls whose surfaces are subjected to embossing processing to obtain uniform roughness on the surface thereof. CONSTITUTION:Coated paper cloth 2 obtained by impregnating a base material with a resin passes through rolls 3 subjected to knurling processing within a drying and curing apparatus 1. If necessary, roughness is further imparted to the surface of the coated paper cloth 2 using a grinding agent. When the surface roughness of the coated paper cloth is uniform, the irregularity of the load applied to the surface of the coated paper cloth at the time of pressing is reduced and, further, the coated paper cloths are not closely bonded each other when they are superposed one upon another and the remaining of air is hard to generate at the time of the degassing due to a vacuum press. The resin is semicured in the drying and curing apparatus 1 and, in this state, notches are applied to the coated paper cloth by the rolls 3.

Title: Hot/cold water mixing device
Inventor: SHIRAI SHIGERU
IPC: F16K31/04
Filed: 1994-10-31
Abstract: PURPOSE: To promote a mixture of hot/cold water so as to quickly detect a mixed temperature with high precision by arranging a mixing part provided with plural bending parts on an outlet side of a hot/cold water mixing valve and arranging a mixed temperature detector detecting a mixed temperature in the downstream of the bending parts. CONSTITUTION: When both hot water inlet port 18 and a cold water inlet port 19 are opened halfway by means of a valve element 12, hot water flows into the inside of the valve element 12 from a hot water flow-in path 15 so as to flow out to an outlet port 20 along a partition wall 21. At the same time, cold water flows into the inside of the valve element 12 from a cold water flow-in path 16 so as to flow out to the outlet port, 20 along the partition wall 21. In this process, hot water and cold water are mixed together while flowing in normal direction parallely to each other by means of the partition wall 21. A mixed temperature detector 33 is arranged on the downstream side of bending parts 35, 36 of a mixing path 34 arranged on the outlet side of a hot/cold water mixing valve 11.  In this way, hot water and cold water flowing out from a mixing flow-out path 17 are mixed together by means of plural bending parts 35, 36, and then, a mixed hot water temperature is detected, so that precise and quick detection can be accomplished.

Title: Thickness measuring apparatus for liquid crystal layer
Inventor: YANO TOMOYA
IPC: G01B11/06
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a thickness measuring apparatus for a liquid crystal layer which permits highly accurate and simple measurement of the thickness of the liquid crystal layer. SOLUTION: A liquid cell 14 is held between polarizers 12 and 13 made rotatable by an equal angle each in the opposite direction to each other around an optical path to derive the thickness of a liquid crystal layer from an angle of rotation of a photodetector 17 as given when an output of the photodetector 17 reaches an extremal value. This enables deriving of the thickness of the liquid crystal layer free from effect of characteristics of a phase difference plate or the like to eliminate the need for a wavelength dispersion data in the anisotropy of refractive index of a liquid crystal material or the like and thus there is no need for due consideration given to the refractive index and the absorption of a color filter, an orientation film or the like.

Patent JP-H03133755-A (JP)
Title: Heat-shrinkable packaging material
Inventor: UMEDA TOZO
IPC: B65D65/38
Filed: 1989-10-13
Abstract: PURPOSE:To pack a number of goods without bent or warp by a method wherein folding rule lines having a depth of a particular ratio to the sheet thickness are made nearly perpendicularly to the direction of larger shrinkage ratio of a heat-shrinkable sheet. CONSTITUTION:A heat-shrinkable sheet 1 with heat-shrinkability is of a mono- or composite-sheet of polypropylene, polyvinyl chloride, polyester, polycarbonate or others, and has a thickness of 0.1 - 1.0mm and a heat-shrinkage ratio of 10 - 80% at 100 deg.C in a minute. Folding rule lines 2 made on the heat-shrinkable sheet 1 have a depth of 5 - 80% of the sheet thickness. If the depth is less than 5% of the thickness, the sheet can not be folded along proper lines due to poor folding ability, and if it is deeper than 80%, the sheet is subject to break due to heat-shrinkage stress as the strength is lowered along the folding rule lines 2. Perforate lines can be substituted for the folding rule lines 2. When the folding rule lines 2 are made at a lower temperature than the heating temperature for heat-shrinking, the folding rule lines 2 restore their original thickness when heat-shrinking takes place, so that a packing material having a high strength can be produced.

IPC: G11B19/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To quickly read out TOC(table of contents) information at the time of loading a disk without using a limit switch. SOLUTION: A recorded EFM (8-14 modulation) signal is read out by an optical pickup head 12 from an optical disk 10 driven by a motor 11 to rotate at a constant linear velocity in a TOC position of the optical disk 10, and is amplified by an amplifier 13 and is then sent to a signal processing circuit 20, where an inverted frequency value is detected. The detected inverted frequency value is sent to a calculating function part 41 of a control circuit 40, where a comparison is made with an inverted frequency value of a reference EFM signal to obtain the present position of the optical pickup head 12 in the radial direction of the disk. A head transfer amt. is obtained from the evaluated head position in the radial direction of the disk and the TOC position, and hence the optical pickup head 12 is transferred in the radial direction of the disk by this amt. to access the TOC.
