Inventor: YOSHIDA SHINJI
IPC: H01C17/06
Filed: 1982-09-30
Abstract: PURPOSE:To eliminate the need for an independent process in which a foundation layer is generated by removing the unnecessary section of a tantalum film by an etching liquid and plasma-etching the film by CF4 gas containing several % O2 gas when forming a tantalum electrode in the manufacture of the thin-film hybrid integrated circuit in which a tantalum capacitor element and a tantalum resistance element are formed to the same substrate.

The unnecessary section of a resist film coated on the surface of the tantalum film 20 is etched, and a resist layer 21 coating the surface of the prearranged tantalum electrode 13 is pattern-formed. When CF4 gas containing several % O2 gas is enclosed in a reaction pipe and the tantalum film 20 is etched by a plasma etching means generating high-frequency plasma, the tantalum electrode 13 is left under the resist layer 21 while a Ta2O5 layer (the foundation layer) 14 is formed on the surface of the substrate not coated with the resist layer 12 through the same process.

Title: Variable resistor
Inventor: MAEDA RYOICHI
IPC: H01C10/10
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To improve controllability by permitting the center of a resistor body pattern to protrude to the side of a conductive contact point, permitting the conductive contact point to be deformed so as to vary its contacting area with respect to a resistor body pattern through the pressing control of a support member, and allowing resistance value to be variable. SOLUTION: In a variable resistor, when the upper portion of a support 6a which faces a resistor body pattern 5 is pressed, a leg 6b is imparted with elastic deformation, and further a curved surface 7a of a conductive contact point 7 comes into contact with the protruded center of the resistor body pattern 5. When the support 6a is kept pressed, the curved surface 7a comes into contact with the conically protruded resistor body pattern 5, while being deformed to gradually increase the contacting area and vary the resistance value at both ends of the resistor body pattern 5, thereby being imparted with a function as a variable resistor.  When the support 6a is released from being pressed, the support 6a is restored to the original state by the elasticity of the leg 6b itself, and further, the contacting area of the curved surface 7a with respect to the resistor body pattern 5 is reduced while varying the resistance value to restore the original state.

Filed: 1988-07-11
Abstract: PURPOSE:To widely control the magnetic tape speed from a low speed to a high speed with simple constitution by performing a tape speed control with an output of a prescribed detector for detecting the tape traveling speed. CONSTITUTION:Light from an LED 38a passes along its course 41 to make incident upon a phototransistor (PT) 33a. Rotational displacement of a roller 23 is converted into an electric output of the PT 33a because the light is interrupted by slit plates 35a and 35b. Then, light from an LED 38b passes along its course 42, and since this light is interrupted by a slit pattern 23a of the roller 23, it is converted into an electric output of a PT 33b. Output signals 33c and 33d from the PTs 33a and 33b respectively for the tape speed detector 33 inclusive of the roller 23 are changed over to be inputted to a control circuit 31, and in response to this input, reel base driving devices 26 and 28 are controlled on their driving rotational speed. By this method, the tape speed can be controlled over a wide range.

Title: Jitter processing circuit
Inventor: KAITE OSAMU
IPC: H04N9/89
Filed: 1989-07-04
Abstract: PURPOSE:To attain the correct detection of jitter by continuing the A/D conversion with only a phase modulated clock having no switching for detection of the jitter value and controlling the phase shift value of the phase modulated clock in accordance with the detected jitter value and the jitter value corrected before 1H. CONSTITUTION:The synchronizing separator pulses are inputted to a burst flag generating circuit 10 and a tape H delay circuit 11. These circuits 10 and 11 produce and output the burst flag pulse and the delay pulse in consideration of the delay value produced by a video delay circuit 3. The A/D conversion output which is delayed and outputted from the circuit 3 is inputted to a jitter fluctuation detecting circuit 9'. Then the jitter fluctuation data is detected based on the value of the A/D conversion output set against a specific reference clock of a burst period. The jitter correction value is kept within a prescribed range by an emitter 22 for production of the jitter correction data. Thus the A/D conversion is usually carried out by only a phase modulated clock. As a result, the stable and sure jitter correction is attained.
