Title: Current control system for power converter
Inventor: OBARA MASAKI
IPC: H02P7/292
Filed: 1986-06-27
Abstract: PURPOSE:To always optimally control a power converter by using as a current feedback amount the mean value of a set current value and a momentary current value when the deviation between them is smaller than a predetermined value, and the momentary value when the deviation is larger than the predetermined value. CONSTITUTION:A current mean value detector 5 and a current momentary value detector 6 detect a current flowing to a stationary power converter 2, the former detects the mean value between firing signals, and the latter detects the momentary value when the current amplitude value after outputting a firing signal becomes the mean value of AC waveforms. The output of the detector 5 is selected in the state that the difference between the current set value and the current momentary value is small, and a current regulator 9 selects the optimum proportional constant and an integration constant for the mean current value. When the difference between the current set value and the current momentary value is large, a converter 8 selects the output of the detector 6, and the regulator 9 alters the control constant to regulate the current.

Title: Satin surface forming method of spectacle frame made of metal by using irradiation method with laser
Inventor: MOTOZUKA KAZUNORI
IPC: B23K26/00
Filed: 1990-06-07
Abstract: PURPOSE:To inexpensively form delicade and fine ornamental patterns consisting of a satin surface by irradiating the prescribed positions on the surface of the spectacle frame consisting of a metal as its base material with a laser, thereby forming fine ruggedness on the surface. CONSTITUTION:The spectacle frame is worked by using, for example, pure titanium as its base material and thereafter, the surface of the spectacle frame is irradiated with the laser. The irradiation with the laser is executed by using a laser marking device ('SL475R' produced by NEC) having a laser oscillator ('Nd: Laser SL115R' produced by NEC) which emits an Nd:YAG laser and by setting the processing speed of the laser marking device at 80 mm/sec. The titanium is evaporated by the heat while the evaporation is finely unequaled on the inadiated surface, by which the satin surface is formed thereon. Different kinds of the ornamental patterns are formed simply by changing the marking patterns of the laser marking device which is an automatic control system. The production of diversified kinds in small lots is thus possible.
