Title: Production of calsium phosphate type spherical apatite
Inventor: NISHITSUJI TOSHIHIKO
IPC: C01B25/32
Filed: 1993-09-28
Abstract: PURPOSE:To obtain a calcium phosphate type spherical apatite after dispersing a liquid portion consisting of an acid as a major component into an organic solvent which is hardly soluble with water, and by mixing and dispersing a self hardening calcium phosphate or a mixture of a hardly soluble fluoride compound with the phosphate, with the above mixture. CONSTITUTION:A liquid portion consisting of an acid such as citric acid as a major component is added dropwise as a hardening enhancer and is dispersed into an organic solvent which is hardly dissolved with water. Into the above dispersion under stirring at approximately 10-1000rpm, a powderly self hardening calcium phosphate having a particle diameter of approximately 100mum or less, of which atomic ratio of Ca/P is in a range of 1.3-2.0, such as an alpha type calcium tertiary phosphate, or a mixture of the powderly self hardening calcium phosphate and a hardly soluble fluoride compound of which ratio of Ca/F (g atomic ratio) is approximately in a range of 4.2-60, such as MGF2, is added and mixed, and after mixing for a predetermined period of time the mixture is kept standing for development of the apatite. After washing the benzene solution, the mixture is kept under water to transfer the product into water, and then the calcium phosphate type spherical apatite is obtained by heating and drying the product.

Title: Mach-zehnder interferometer type optical multiplexer/ demultiplexer
Inventor: KAWACHI MASAO
IPC: G02B6/34
Filed: 1985-10-28
Abstract: PURPOSE:To reduce an optical propagation loss at a bending part by coupling two directional couplers formed on a plane base by two single mode optical fibers fixed on the other base to constitute an optical multiplexer/demultiplexer. CONSTITUTION:The bases 31a, 33, 31b are coupled with each other so that the optical axis of the optical waveguide constituting each direction coupler coincides with that of the corresponding single mode optical fiber core part. Optical signals f1, f2 being made incident from one end of the directional coupler 32a are respectively equally divided by the coupler 32 and the equally divided signals are transmitted to the single mode optical fibers 34a, 34b and interfered with each other by the directional coupler 32b. However, the optical signal f1, f2 can be multiplexed and extracted from either one of output terminals of the coupler 32b, and if reverse operation is executed, optical signals can be also demultiplexed. Consequently, the optical propagation loss can be reduced.

Title: Elecrifying device storing electroconductive particle in form of granule and agent for accelerating electrification
Inventor: KONO YASUNORI
IPC: G03G21/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently treat particles capable of accelerating electrification, to uniformly supply the electrification accelerating agent and to improve treatability of the electrification accelerating agent, in the electrifying device using electroconductive particles as the electrification accelerating agent. SOLUTION: Supplying and coating of electroconductive particles m to an electrifying member 2 are made uniform in the longitudinal direction of the electrifying member 2 by storing the electroconductive particles m as electrification accelerating particles in the form of the granule M, and then shaving the granule M to obtain fine particles m. Further, the amount of coating of the electroconductive particles m onto the electrifying member 2 is made appropriate and the multi layer coating of the electroconductive particles m can be avoided, and furthermore, falling off of the electroconductive particles m stuck on the electrifying member 2 to a body to be electrified is inhibited.  As the electroconductive particles m are stored in the form of the granule M, without directly storing the electroconductive particles m which are fine particles having small particle diameters, scattering of the electroconductive particles m is suppressed to be low and treatability of the electrification accelerating agent is also improved.

Then the target value is corrected according to the relative position relation.  A steering control means performs guidance control so that a detected value of the magnetic field detecting means reaches the corrected target value.

Filed: 1993-09-29
Abstract: PURPOSE:To maintain read precision even if external noise is large by stopping the output of a sense line group when a loop-formed noise detection line arranged on a tablet detects the noise of more than a prescribed value. CONSTITUTION:The noise detection line 20 is arranged on the tablet 21 so that it surrounds an exciting line group 2 and the sense line group 3, and it is connected to a noise detection circuit 22. When an electromagnetic signal is generated by a CRT display device for horizontal scanning, an AC signal SN is generated in the noise detection line 20. The noise detection circuit 22 amplifies the inputted AC signal and selects the AC signal of 300-600kHz. When the output voltage is larger than reference voltage, a switch 26 stops the output of a detection signal IS from a sense line 3, and sets a phase detection circuit 7 and an amplification detection circuit 8 to a temporary stop state. When output voltage from the noise detection circuit 22 becomes smaller than reference voltage, the switch 26 outputs the detection signal IS so as to resume an operation.

Title: Calibration method of image deformation for shape measuring apparatus
Inventor: OGAWA GAKUO
IPC: G06T7/00
Filed: 1994-10-06
Abstract: PURPOSE: To provide the calibration method, of an image deformation for a shape measuring apparatus, in which the image deformation can be calibrated precisely in a state that an imaging device has been installed in a shape measuring position. CONSTITUTION: A constitution plate 3 on which a plurality of constitution marks 4 have been formed is arranged and installed in the imaging position of an object to be measured, and it is imaged by an imaging camera 2 which is arranged in a measuring position. When positions of the constitution marks 4 on an image which has been imaged are compared with positions on a known calibration plate, the degree of the image deformation of the imaging camera 2 can be operated. As a result, the image deformation is calibrated by using an operated value as a calibration amount. When a lengthwise and breadthwise unequal magnification lens is used for the imaging camera 2, the image deformation becomes large. However, the image deformation can be calibrated by this calibration method.  The calibration marks 4 in this case are formed to be shapes which are proportional to the ratio of the lengthwise and breadthwise unequal magnification of the lengthwise and breadthwise unequal magnification lens. In addition, the positions of the calibration marks on the image can be detected by finding their center-of-gravity positions.
