Title: Drive device for ac motor
Inventor: TANAKA SHIGERU
IPC: H02P23/16
Filed: 1984-03-26
Abstract: PURPOSE:To eliminate to flow an excess current from a power source at a recovering time by maintaining the DC voltage of a smoothing condenser substantially constant by a regenerative control at an instantaneous power interruption time. CONSTITUTION:If a motor IM is disposed at a crossover track to instantaneously interrupt a power when the motor is operated with power, the output signal Ism of a DC voltage controller AVR increases to exceed the set level of a Schmitt circuit SH. Then, a switch circuit SW which is connected to a side so far is converted to (b) side. Accordingly, the torque command value T'e* of the motor IM becomes negative value and hence a regenerative command. Thus, the rotary energy of the motor IM is regenerated to a smoothing capacitor Cd. Thus, the DC voltage Vd of a smoothing condenser Cd does not extremely decrease, but even if a power source voltage Vs becomes reenergized state, a converter CONV can be always normally operated.

Title: Method for quantifying shape of laser beam and method for adjusting the laser beam
Inventor: MIHASHI HIROSHI
IPC: H01S3/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for quantifying the shape of a pulse laser. SOLUTION: A yellowish surface 31 of amorphous silicon is produced through the irradiation of a laser beam having low energy density, and as the energy density increases, a reddish region 32 appears (A), and when the energy density increases further, a greenish yellow or yellowish green region 33 appears (B). When observing a region irradiated with the laser having a high energy density, the entire region appears greenish yellow (C), and the difference in energy density disappears.  This state can be specified by the energy meter of the laser measured, when the laser beam is applied and can be expressed as the profile of the overall beam by overlaying the region having high energy density on the region having lower energy density by using the energy meter value and so on of each irradiation of the laser as a contour line, whereby the nonuniformity of the plateau region of the laser beam can be quantified. Based upon it, optical parts can be adjusted.
