Title: Positioning device for glass substrate
Inventor: SAKAKAWA HIDEO
IPC: G09F9/00
Filed: 1988-10-26
Abstract: PURPOSE:To shorten the positioning time of a square glass substrate by photodetecting reflected light which is reflected by the glass substrate and corresponds to irradiation area and computing the quantity of a position shift from four detection outputs as to the peak of the small level of the photodetection output in one turn of the glass substrate.

Title: Vacuum evaporation method of cr by electron beam heating system
Inventor: TERADA MAKOTO
IPC: C23C14/30
Filed: 1992-10-08
Abstract: PURPOSE:To greatly improve the erosion resistance of an evaporation chamber essentially consisting of graphite, thereby prolonging the life and to form a high-purity vapor deposited film by electron beam heating a specifically composed Zr-Cr alloy to a specific bath temp. within this evaporation chamber. CONSTITUTION:Cr is vacuum evaporated by the electron beam heating and the plating layer of the vapor deposited film is formed on the surface of a material to be treated. The evaporation essentially consisting of the graphite is used in the above-mentioned vacuum evaporation method of the Cr. Further, the alloy bath of the Cr contg. 50 to 90wt.% Zr is formed within this evaporation chamber and the bath temp. of the Zr-Cr is maintained at <=1700 deg.C. This alloy reacts with the graphite and forms stable ZrC and Zr-CrC on the inside wall surface of the evaporation chamber, by which the erosion is prohibited and the intrusion of impurities into the bath is prevented. Further, only the Cr evaporates stably from this bath and the vapor deposited film which is uniform and does not contain the impurity elements is formed. The life of the evaporation chamber is thereby prolonged and exchange frequencies are decreased. The continuous productivity is thus improved.

A vector control operating section 22 performs vector control operation based on the reference torque tauR and the flux command phi* thus controlling the torque of an induction motor. Since flux current is increased prior to increase of output torqe by delaying the torque command tau* to establish a necessary flux, high efficiency is achieved through field current control with torque and stability can be ensured in the control system at the time of high torque output.
