Title: Band stop filter
Inventor: NAKAMURA MASAO
IPC: H03H7/07
Filed: 1982-03-19
Abstract: PURPOSE:To set easily the attenuation quantity of an attenuation pole at approximately infinity, by securing the same amplitude and opposite phase between the electric wave transmitted to an output terminal via a primary resonance circuit and that transmitted to the output terminal via a secondary resonance circuit in terms of resonance frequency. CONSTITUTION:The electric waves supplied to an input terminal 11 are divided to those that are transmitted to a primary resonance circuit 14 via a variable coupling capacitor C1 and others that are transmitted to a secondary resonance circuit 15. The electric waves of the circuit 15 are synthesized again with those sent via the circuit 14 by a variable coupling capacitor C2 of the output side and via a coaxial cable l. Therefore the amplitude (degree of attenuation) is controlled by the capacitors C1 and C2, and at the same time the phase shift (electric angle) is controlled by the cable l. As a result, the same amplitude and opposite phase are secured between the electric wave that reaches an output terminal via the attenuation pole (resonance frequency) of the circuit 14 and the electric wave that reaches the terminal 12 via the circuit 15. Thus the electric waves which are synthesized at the terminal 12 are eliminated with each  other, and therefore the attenuation quantity is set approximately at infinity at the  attenuation pole.

Title: Glow discharge emission spectral analyzer
Inventor: FUKUI ISAO
IPC: G01N21/67
Filed: 1987-02-27
Abstract: PURPOSE:To stabilize an analysis by providing a feedback system which detects the internal resistance of a glow discharge tube using a sample as a cathode and maintains the internal resistance of the glow discharge tube at approximately a constant level and maintaining a sputtering rate automatically at a constant value. CONSTITUTION:Gaseous argon is admitted through an inflow port 5 into the glow discharge tube G and is discharged from outflow ports 6 and 7. A flow rate control valve V is otherwise inserted into, for example, a gaseous argon supply pipe and the voltage drop generated across a resistor (r) connected in series to the discharge tube G is detected by a current detector D to control a valve driving device P via a comparator C, thereby opening and closing the valve V. The internal resistance of the discharge tube G increases and the tube current increases when the sputtering rate of the sample is low. The valve V is then opened to increase the gaseous argon pressure, by which the internal resistance is decreased and the sputtering rate is maintained constant. The stable analysis is thereby executed.

Filed: 1987-02-27
Abstract: PURPOSE:To decrease wire breakdown defects due to thermal stress to wirings, by bringing the linear thermal expansion coefficients of an aluminum wiring and a covering insulating film thereof closer. CONSTITUTION:A silicon oxide film 12 is formed on a silicon substrate 11. Thereafter, an aluminum film 13 including, e.g., 0.5% Si, is deposited on the entire surface by a magnetron sputtering method. Then, the aluminum 13 is selectively etched by using a reactive ion etching method. As a covering insulating film 14 for the aluminum film 13, which forms a wiring layer, an insulating film, e.g., CaF2, whose linear thermal expansion coefficient is 9X10<-6>K<-1> or more, is formed on the entire surface by an electron beam evaporating method. Namely, the target of CaF2 is sputtered with an electron beam, and the sputtered CaF2 is deposited on the entire surface. Since thermal stress acting on the aluminum film 13 in manufacturing process or in operation of a semiconductor device becomes remarkably small, wire breakdown defects can be prevented.

Title: Developing method by magnetic brush
Inventor: WATANUKI TSUNEO
IPC: G03G9/113
Filed: 1987-03-02
Abstract: PURPOSE:To widen the tolerance width of a toner concn. by using a two- component type magnetic developer obtd. by mixing a magnetic carrier consisting of fine powder of iron bonded by an amine-modified resin and insulating toner having negative electric chargeability. CONSTITUTION:The fine powder of iron is bonded by the amine-modified resin to form the magnetic carrier having 15-40mum average grain size. The fine powder of iron which has >=80emu/g magnetization to 1kOe magnetic field and 0.2-2mum average grain size is used at this time. The fine powder of iron is incorporated into the carrier in a 50-80wt.% range of the total weight of the carrier. Such magnetic carrier is mixed with the insulating toner having the negative electric chargeability and 5-15mum average grain size to yield the two-component type magnetic developer. An electrostatic latent image is then developed by a developing method by a magnetic brush. Since the magnetic carrier of the small grain size is used, the tolerance width of the toner concn. is widened and the need for a mechanism to control the toner concn. is eliminated. Formation of a sharp image is thus permitted.
