Abstract: PURPOSE:To shorten the time needed for restorage of a broken-down computer by adding an automatic monitor part which loads previously and automatically the image of a computer having a high trouble rate or the computer presumed to have a trouble next into a lower-rank computer for back-up. CONSTITUTION:The image of a programmable controller Pc having the highest trouble rate is loaded previously into a back-up Pc6 via a transmission controller 7 by means of the MTBF (Mean Time Between Failures) of those Pc3-5 which are automatically monitored by a process computer 1. When the image of the Pc whose trouble is estimated is loaded, the estimated time of the trouble is obtained from the MTBF of Pc3-5 and the working duration time. Then the Pc having the minimum estimated time of the trouble is loaded previously and automatically into the Pc6 through the controller 7. As a result, the image loading job probability is reduced in a Pc breakdown mode and the restoring time of a broken-down computer is shortened.

Title: Photoelectric conversion device
Inventor: NISHIKURA TAKAHIRO
IPC: H04N1/19
Filed: 1983-12-22
Abstract: PURPOSE:To improve the optical response characteristics of a complete adhesion type direct reading photoelectric conversion device by simultaneously irradiating a photoelectric conversion element with a bias in the fixed amount of light from the back of the photoelectric conversion element together with reflected beams from a draft. CONSTITUTION:Beams from a light source 7 are projected from the back of a glass substrate 1 through a lighting window 3, and transmitted beams 10 from a light-shielding film 2 are introduced to a photoelectric conversion elememt 5 as bias beams in a fixed amount together with reflected beams 9 from a draft surface 8. Since bias beams are applied in this manner, optical response is reduced, and the speed of operation of a facsimile, etc. can be increased. Since bias beams in the fixed amount of light are projected to the photoelectric conversion element at all times in comparison with reflected beams as a draft signal, on the other hand, an S/N ratio is lowered, but the ratio is negligible when it is brought to 1/10 or less.

Filed: 1992-09-11
Abstract: PURPOSE:To always enable optimum vibration correction corresponding to photographic conditions and states by changing the frequency characteristic of a vibration correcting means corresponding to the frequency band of vibrations at the time of photographing. CONSTITUTION:A phase shift amount to be generated at each frequency is calculated from the frequency characteristic of an angular velocity sensor 1, and the corrected value of the frequency characteristic required for correcting the phase shift generated at that time, concretely, the resistance value of a variable resistor R1 is arithmetically calculated for each vibration frequency. Therefore, the rotation of a variable resistance control motor 16 is controlled corresponding to the frequency detected by a frequency detector 12, and a correction circuit 14 sets corresponding relation between the resistance value of a resistor R2 and an F/V converter 13 so that the resistance value for correcting the phase shift generated at the frequency can be automatically set to the variable resistor R1. Thus, the frequency not to generate the phase shift is always set to an HPF 2' corresponding to the change of the vibration frequency, and high vibration-proof effects can be provided regardless of the vibration frequency.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a highly sensitive and stable analyzing device by constituting a spectral analyzing device cone by use of a special material consisting of an element not to be analyzed. SOLUTION: A cone 10 has an optical passage port 103 bored along the conical axis, which forms a tapered optical path increased in diameter from the plasma side of the cone tip part toward the spectroscope side of the bottom.
