Title: Detecting and reading method for absolute angle position
Inventor: TAKAMIYA YUTAKA
IPC: G01D5/245
Filed: 1987-07-08
Abstract: PURPOSE:To meet an origin position without adjusting the fitting position for a angle of a resolver by adjusting a reference voltage for the detection of a detection signal and synchronizing reference zero output points of respective resolvers. CONSTITUTION:The reference voltage for one of mutual detection signals 21 and 22 outputted by a bipolar resolver 1 and a multipolar resolver 2 is adjusted to adjust the phase. The detection signals are synchronized with the reference zero output points of those detection signals, and counted and read. In such a case, a comparison reference voltage V1 inputted to the operational amplifier 25 of a waveform processing circuit for the signal 21 is adjusted by a variable resistor VR 26 to move the origin of the resolver 1 to the origin of the resolver 2. Then the signal waves obtained by processing the waveforms of the signals 21 and 22 are read in the form of absolute values at the angle position of the shaft 5a of a machine device 5. Therefore, the fitting positions of the resolvers 1 and 2 need not be adjusted, so the resolvers 1 and 2 are easily fitted to the device 5.

Title: Manufacture of thin film
Inventor: TAMURA MASAO
IPC: H01L21/205
Filed: 1982-10-01
Abstract: PURPOSE:To deposite a material such as semiconductor to form a thin film on only a required domain of a water made of semiconductor or other material by performing heating of the substrate and gas reaction at the same time by one laser source. CONSTITUTION:By one laser source 1 substrate heating and gas reaction are performed at the same time and material is deposited on the surface of a substrate wafer 2. For instance, when the introduced gas 3 is SiH4, this gas has a sharp absorption at the wavelength of 10.55mum and Si is precipitated by vibrating excitation, so only the light of 10.55mum wavelength of a CO2 laser 1 is selected by a spectroscope 4 and introduced into reaction system 5. On the other hand, a laser beam which is bent by a half mirror 6 and has wavelength of 10.6mum is radiated upon the substrate 2 and heats the silicon substrate. The absorption coefficient of the Si substrate by the 10.6mum laser beam is very small and heating does not occur by absorbing effect into the lattice system but the absorbing effect by free electron is large and sufficient temperature rise can be obtained by heating for only several seconds.
