Title: Production of diamond thin film or diamond-like thin film
Inventor: FUKUDA TOMIYO
IPC: C23C16/27
Filed: 1987-01-27
Abstract: PURPOSE:To form a high-quality thin film efficiently, by introducing a reaction gas to a vacuum tank, generating microwave plasma and bringing the plasma into contact with a raw material containing carbon activated by a thermoelectron emitting material. CONSTITUTION:When a magnetic field is applied in a vacuum tank 1 by placing an electromagnet 7 to produce about 875 gauss and microwave is introduced from a waveguide 2, Electron Cycloton Resonance is formed in the vacuum tank 1. A reaction gas g0 is fed to the vacuum tank and plasma discharge is generated. Separately, a carbon-containing raw material g1 such as methane is sent from a raw material inlet part 4 in the vacuum tank 1. Methane is decomposed by the use of a thermoelectron emitting material 8 and brought into contact with hydrogen plasma to grow a diamond thin film or a diamond- like thin film on a substrate 5. When a substrate holder 6 can be heated or cooled, the diamond-like thin film is formed at room temperature and the diamond thin film at >=room temperature.

Title: Drive circuit for motor
Inventor: TSUKIHASHI AKIRA
IPC: H02P7/288
Filed: 1983-02-03
Abstract: PURPOSE:To stabilize a tape feeding speed constantly substantially over the entire feed by applying a constant voltage to the armature winding at a light load time, and applying a voltage in response to the counterelectromotive voltage to the armature winding at a heavy load time. CONSTITUTION:A power source voltage VB is supplied to the armature winding 1 of a motor, and also applied to a controller 5 through a compensating resistor 2 and dividing resistors 3, 4. Since the load is small at the starting time of winding a tap, the current IM flowed to the winding 1 is small, and the constant voltage determined by a constant-voltage element 9 is supplied to the winding 1. When the tape is wound and the load applied to the rotor increases, the current IM increases to cut off the element 9. In this manner, the controller 5 controls a branch transistor 7 and a drive transistor 8 in response to the difference between the counterelectromotive force produced at the winding 1 and a reference voltage.
