Title: Nonlinear optical material having polarization inversion structure, and its production
Inventor: KOTOU MASAHIRO
IPC: G02F1/37
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily produce a material having a polarization inversion structure large in a crystal thickness, by forming ruggedness satisfying specific conditions on a surface having polarization inversion regions. SOLUTION: The ruggedness is formed on the surface 2 having the polarization inversion regions of the nonlinear optical material 1 having the polarization inversion structure. The ruggedness is fitted to the ruggedness of the other nonlinear optical material 3 having the ruggedness on the surface having the polarization inversion structure of the same period and having the polarization inversion regions with each other. The shape of the ruggedness is not particularly limited so far as such reggedness. The depth of the ruggedness is not particularly limited if the ruggedness has the restraining force capable of fixing the positional relations of the nonlinear optical materials with each other. For example, the depth is about 0.1 to 100μm, more preferably about 1 to 100μm.  The ruggedness formed on the nonlinear optical materials is eventually formed to meet the polarization inversion periods by using wet process etching when, for example, lithium niobate is used.

Title: Torque calculating device
Inventor: KANEKO KIMIHIKO
IPC: H02P29/00
Filed: 1980-04-30
Abstract: PURPOSE:To calculate accurately a torque by considering the parameter of a load current in addition to the parameter of revolution as a fixed loss and also considering the brush electric loss in addition to the resistance loss as a direct load loss. CONSTITUTION:The sum of a terminal voltage Va, an armature resistance voltage drop IaRa and a brush voltage drop Vb is divided by a revolution N. A limiter L1 produces a coefficient K when the revolution N is lower than the lower limit revolution and a value divided as above when the revolution N is higher than the lower limit revolution. On the other hand, the sum of the value obtained by multiplying the differential loss PI of the total load and no load of the fixes loss by a current Ia and a no load loss PL is divided by the revolution N. A limiter L2 produces a coefficient F when the revolution N approaches zero and a value divided as above when the revolution N is except the vicinity of the zero. Thus, the sum of the value obtained by multiplying the output of the limiter L1 and the current Ia and the output of the limiter L2 is outputted as a calculated torque.
