Title: Method for automatically recognizing inserted substrate
Inventor: KOIZUMI MINORU
IPC: G06F13/14
Filed: 1992-12-11
Abstract: PURPOSE:To surely prevent the erroneous operation of a controller due to erroneous insertion of an inserted substrate by encoding the classification and the revised number of the inserted substrate to store them in the code specification circuit of the substrate and issuing a command to the control circuit of the inserted substrate by the address coincidence circuit of the inserted substrate to recognize the inserted substrate. CONSTITUTION:A code indicating the classification and the revised number of an inserted substrate 3 is stored in the code specification circuit of the inserted substrate 3. When the inserted substrate 3 is inserted to a substrate circuit 7 and a controller is started, a CPU substrate 1 reads data in a pertinent address of the inserted substrate 3 through a bus 2, and then, an address coincidence circuit 4 issues a command to a control circuit 5 to generate the code to the bus 2 from the code specification circuit 6. This circuit 6 receives this command to output its own code to the bus 2. The CPU substrate 1 reads this code to recognize the classification and the revised number of the inserted substrate 3.

Abstract: PURPOSE:To control the tracking of plural luminous fluxes adequately in both a radial direction and a tangential direction by dividing reflected light from a record carrier into two parts by an optical path separating means and detecting independently the track error signals of two spots, at least, from the luminous flux of the divided one side. CONSTITUTION:The luminous fluxes alpha, beta radiated from a semiconductor laser with two luminous points, i.e., an LD array 10, are converged on the same track Tr on a disk 50 as the spots SA, SB respectively. Then, when the center of the track and the spots SA, SB shift to the radial direction on account of the decentering of the disk, etc., because the balance of the light receiving quantities of light receiving parts H and I, G and J gets worse, the tracking is controlled by a push-pull method as considering the signal (g+h)-(i+j) to be the track error signal in the radial direction. Besides, the spots SA, SB shift against the track Tr in the tangential direction, because the patterns of received light quantities on the respective light receiving parts change, the servo control of the tangential direction is performed as considering the signal (g+i)-(h+j) to be the error signal in the tangential direction.

IPC: G01N21/3563
Filed: 1988-12-27
Abstract: PURPOSE:To make it possible to judge the quality of rice objectively by crushing specimen rice, obtaining the contents of main factors based on the analyzed values obtained by a near infrared-ray spectro-chemical analysis method and predetermined component conversion factor, and obtaining the characteristic values based on predetermined characteristic factors. CONSTITUTION:A container 52 filled with specimen rice 55 is mounted on a mounting box 5. Near infrared-rays having a specified wavelength from a light source 31 are applied on the specimen and on the inner wall of an integrating sphere 3 through a filter 33 and a reflecting mirror 32 by the operation of operating push buttons 7. The amount of the reflected light from a detector 35 and the amount of reference projected light are stored in the memory in a control device 4. The absorbance can be measured based on the difference between both values. When the filter 33 is changed and the wavelength of the projected light is changed, the measured values become the actually measured data for computing the contents of the amylose, protein, fat, water and the like contained in the specimen rice. The component conversion factors and the characteristic factors are determined based on the data of the specimen rice whose components are known are determined. Thus the characteristics can be judged objectively.

Title: Image forming device
Inventor: UIRIAMU JIEI NOWAKU
IPC: G03G21/00
Filed: 1993-12-27
Abstract: PURPOSE: To attenuate the lateral mode vibration of a resonator. CONSTITUTION: A horn 152 is cut through the contact chip 159 and chip part 158 of the horn and is provided with a continuous platform part 156 and a piezoelectric element 150. In the gap 200 of a narrow width formed by the adjacent horn elements, an energy dispersion medium 202 composed of a viscoelastic material such as a Dow-Coning 732 RTV sealant is placed. When the resonator is vibrated in an axial direction, the horn elements are moved mutually in the same phase. When relative movement is not present between the horn elements, energy dispersed in an energy absorbing medium is minimized. When the resonator is vibrated in a horizontal direction, the segments of the horn are operated while making phases different from each other. When the relative movement occurs between the horn elements, energy dispersion into an energy absorbent is maximized.  In such a manner, the component in an undesirable crossing processing direction of the vibration is attenuated by introducing such an energy absorbing medium in the gap between the elements.
