Title: Observation device for multiple optical fiber
Inventor: KAWANISHI NORIYUKI
IPC: G02B6/255
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a driving mechanism which scans an optical path by wavelength variation of a light source and speed up the scanning by using a variable wavelength type light source as a light source and adding a spectral element to an optical system. SOLUTION: The variable wavelength type light source is used as the light source 10 and the spectral element 50 is added to the optical system represented by a lens 30. The variable wavelength type light source 10 can be varied in wavelength continuously or stepwise. The spectral element 50 is an element which shifts in optical path with the wavelength and placed in front of an image pickup element 40. Light 12 with short wavelength travels as shown by the broken line after exiting from the spectral element 50. Consequently, the right part of an array in an enlarged image is observed. Light 12 with long wavelength travels as shown by the dotted line after exiting from the spectral element 50. Consequently, the left part of the array in the enlarged image 22 is observed.  Light 12 with intermediate wavelength travels as shown by the solid line after exiting from the spectral element 50. Consequently, the center part of the array in the enlarged image 22 is observed. Thus, the whole fiber image 22 can be observed.

Title: Step-up and step-down chopper method stop type excitation system for synchronous generator
Inventor: HON-UU RYU
IPC: H02P9/14
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To make a stable operation of a generator by providing an excitation system with a step-down chopper which steps down the terminal voltage of the generator and supplies excitation current and a step-up chopper which steps up the output voltage of the generator when the output voltage of the generator falls and then supplies excitation current. SOLUTION: At normal operation, a switch 170 for a step-up chopper parallelly connected to a three-phase full-wave rectifier diode 120 in a step-up chopper 100 is not driven and a switch 10 for a step-down chopper is driven by controlling a step-down chopper 200 through a magnetic field system 2d of a generator, an input reactor 110, and the three-phase full-wave rectifier diode 120 to supply current to a field magnetic system 2a of the generator 2.  In other words, the teminal voltage of the generator 2 is controlled by the step-down chopper 200 at normal operation and, in the case that the output terminal voltage of the generator 2 falls owing to defect on a transmission line or other troubles and excitation current is insufficient, the switch 170 of the step-up chopper 100 is driven to step up the input voltage and thereby the excitation strengthening capability of the system is secured.

Title: Medium feeding mechanism
Inventor: TSUNOGUCHI KAZUHIRO
IPC: B41J15/04
Filed: 1986-12-17
Abstract: PURPOSE:To ensure that the shocks generated at the time of printing are distrib uted uniformly over the entire surface of a platen and prolong the useful life of the platen, by such a setting that the number of feed pitches corresponding to one rotation of the platen is not an integral number. CONSTITUTION:The rotation of a platen 11 is so set that the number of feed pitches corresponding to one rotation of the platen 11 is not an integral number. This is realized by appropriately setting the number of teeth of a platen gear. The parts (a') receiving the shock of printing during one rotation of the platen 11 and the parts (b') receiving the shock of printing during the next rotation of the platen 11 do not overlap with each other but are shifted from each other. As a result, the shocks generated at the time of printing are distributed over the entire surface of the platen, and therefore, the useful life of the platen can be prolonged without changing the material for the platen or the like.

Filed: 1986-12-16
Abstract: PURPOSE:To improve the creation, compression and integration of information by constituting a holonic loop by a hiper column aggregate, a memory column aggregate, a parallel/serial conversion circuit and a serial/parallel conversion circuit and acting the loop as a positive feedback loop. CONSTITUTION:The holonic loop is constituted by a hiper column aggregate SIGMAH, a memory column aggregate SIGMAM, parallel/serial conversion circuits 101, 103 and serial/parallel conversion circuits 102, 104 and the following conditions are set to act the loop like a positive feedback loop. That is, as the condition 1, a signal outputted from the aggregate SIGMAH is the total sum of holon in the locking state of each hiper plane. As the condition 2, the signal inputted to the aggregate SIGMAM is applied simultaneously to all holons on the hiper planes and only the output signal of the holon in locking state is increased. As the condition 3, the input/output signal of the aggregate SIGMAM is more than the output level of the holon in the locking state and the strength of the locking state is maintained. Thus, the creation, compression and integration of the information are attained more flexibly and quickly.
