Title: Deposition of optical thin film and deposition apparatus
Inventor: MITAMURA NOBUAKI
IPC: C23C14/34
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To deposit optical thin films which are small in light absorption and have mechanical strength. SOLUTION: A discharge gas is introduced into a vacuum camber and a material contg. at least metal fluoride is used as a target. The plasma of the discharge gas is then generated on the target by the high-frequency electric power controlled by a control means and the thin films are formed on a substrate by sputtering the target by the plasma. At this time, the first light emission intensity derived from the molecules constituting the metal fluoride in the plasma and the second light emission intensity derived from the atoms constituting the metal fluoride or the discharge gas are measured. The high-frequency electric power is so controlled that the result of the computation based on the first and second light emission intensities attains a desired value.  The deposition of the thin films which are less in the light absorption and have the high strength is made possible under good control by the deposition control based on the light emission intensity of the molecules constituting the target.

Filed: 1988-02-29
Abstract: PURPOSE:To measure the oscillating frequency externally by applying the oscillation output to all electric resonance elements connected externally simultaneously and applying negative feedback input to an output of an electric resonance element deciding a desired oscillation frequency or its resonance current detection output. CONSTITUTION:A crystal vibrator x1 is connected between a terminal T1 and a circuit ground and a crystal vibrator x2 is connected between a terminal T2 and a circuit ground, and either of the crystal vibrators X1, X2 is given by a two-input changeover switch element S1 to a negative feedback terminal (-) of an amplifier l as a detection voltage. The impedance of the crystal vibrator X1 receiving the detection voltage and a capacitor C1 is nearly zero at the resonance frequency f1 and only a positive feedback signal is fed to the amplifier 1 through a resistor R3 and oscillated at the frequency f1. In this case, since the terminal T2 not selected as the detection voltage gives a high impedance, the oscillated waveform appears via the resistor R2.

Abstract: PURPOSE:To increase the piezoelectric constant, by laminating plural sheets of piezoelectric element films made of a polymer group piezoelectric material in parallel to each other via a propagating medium and then parforming the coupling of travelling waves. CONSTITUTION:The polyvinylidene fluoride (PVDF) films 101-10n having electrodes 2 and 3 on both surfaces are laminated via a propagating medium 20 suited for propagation of ultrasonic waves, e.g., the water, a medium having the acoustic characteristics substantially equivalent to water, the silicone rubber, etc. The both ends of a single PVDF film are held 31 and 32 to keep good plane properties. An acoustic lens 40 is attached at the aperture end on the surface of the film 10 in order to obtain the desired directivity to the ultrasonic beam which is radiated from or arrives at the aperture end. At the same time, a sound absorbing packing material 50 is attached on the rear side of the film 10 to realize the resistive termination. The space (d) between films 10 is not necessarily set constant, and the electrical delay between the films is controlled to perform the excitation (transmission) or the synthesization (reception).
