Title: X-ray detecting device
Inventor: MORIYA ATSUSHI
IPC: G01N23/00
Filed: 1987-02-13
Abstract: PURPOSE:To realize an X-ray detecting device which has no variance in characteristics and a high S/N by constituting a silicon photodiode for photoelectric conversion and an amplifier which amplifies a converted electric signal on the same IC chip. CONSTITUTION:At least silicon diodes 21 and amplifiers 24 in X-ray detection parts ch1-chn for 1st-(n)th channels are constituted on the same IC substrates.

Title: Work discriminating method and device thereof
Inventor: HARADA KOICHI
IPC: B23P19/00
Filed: 1992-02-17
Abstract: PURPOSE:To reduce processing load for discriminating a work by providing an upper/lower limit threshold value changing means to change upper/lower limit threshold values so as to dissolve overlap of both ranges, under the condi tion in which they are discriminated to be overlapped. CONSTITUTION:Feature values of a plurality of works for teaching are extracted, and the feature value of the highest work discriminating accuracy is selected as the work discriminating feature value from the extracted feature values, under the condition the work discriminating accuracy based on the previously set feature value in the extracted feature values is not high. Upper/ lower limit threshold values are obtained based on the mean value and dispersion of the selected feature value, and it is discriminated by a discriminating part 5 whether the ranges based on the upper/lower limit threshold values obtained from every sort of work are overlapped or not. Under the condition they are judged to be overlapped, the upper/lower limit threshold values are changed by an upper/lower limit threshold value changing means 8a so as to dissolve overlap of both ranges, and the objective work is discriminated based on the selected work discriminating feature value and the finally obtained upper/ lower threshold values.

Title: Contact and connecting jig using the same
Inventor: MONMA YUKIMASA
IPC: G01R1/067
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To secure contact with a conductor pattern or the like and set a specified impedance value so as to perform accurate measuring by constructing a contact in a manner that an outer conductor, an insulator and a center conductor are constructed in a coaxial way and one end side of a metallic pin is protruded from one end of the outer conductor. SOLUTION: A contact 1 has a coaxial structure and its characteristic impedance is uniquely decided by the mechanical dimension of an outer conductor 2 or the like, or the dielectric constant of an insulator 3. One end of the metallic pin 6 of the contact 1 is brought into contact with, for instance a conductor pattern, the outer conductor 2 is grounded and thereby a signal for measuring a high frequency circuit is transferred. Since a center conductor 4 as a route for the signal is shielded by the outer conductor 2, the guiding of external noises or interfering signals to the center conductor 4 is prevented. Further, since the contact l has a coaxial structure, its characteristic impedance is set to a specified value, for instance one to coincide with the I/O impedance of a high frequency circuit, and thus an accurate measured value is secured.

Title: Manufacture of composite ferrite
Inventor: SUGIYAMA SHUNICHI
IPC: H01F1/34
Filed: 1993-02-19
Abstract: PURPOSE:To produce a composite ferrite whose component ratio is substantially identical to a solution component by reducing a liquid drop size of an aqueous solution which contains more than two kinds of metal ions below a specific dimension. CONSTITUTION:An aqueous solution, which contains more than two kinds of metal ions, is atomized where the liquid drop size of liquid drop particles at that time is specified to be 150mum and below. The thermal energy of combustion gas generated at a burner is supplied to this aqueous solution, thereby evaporating the water content of the liquid drops, thereby allowing residual metal salt particles to produce thermal cracking or chemical reaction with the thermal energy. During this time, the water content of the atomized liquid drop particles are evaporated spontaneously, thereby producing quick roasting. This construction makes it possible to obtain a composite ferrite whose component ratio is substantially identical to a solution component.
