Title: Method of manufacturing semiconductor device
Inventor: SHIBATA KENJI
IPC: H01L21/28
Filed: 1978-09-28
Abstract: PURPOSE: To improve the tight fitting property of films of a metal of high melting point or a silicide thereof to a semiconductor substrate or an insulating film, by separately coating the films at several times and continuously treating these films with heat at each time of coating.  
     CONSTITUTION: An insulating film 2 is provided on the surface of a semiconductor substrate 1 of an electroconductive type. A part of the film 2 is removed so that a thin insulating film 3 is provided and a shaped workpiece is obtained. A metal of high melting point or a silicide thereof is coated at a thickness less than a prescribed value on the substrate 1. The films and the substrate are then continuously treated with heat under an atmosphere of inert gas. Coating and heat treatment are thereafter repeated so that a metal film 4 of the metal or the silicide thereof is produced at a desired thickness. A gate electrode film 5, a source region, a drain region, a source electrode 12, a gate electrode 13 and a drain electrode 14 are then produced by conventional methods. This results in improving the tight fitting property of the metal of high melting point or the silicide thereof to the semiconductor substrate or the insulating film and in enabling high-speed operation and high-degree integration based on self-arrangement.

Title: Constant current circuit
Inventor: KATAYANAGI TAKASHI
IPC: G05F5/00
Filed: 1978-09-30
Abstract: PURPOSE: To make the output current substantially constant irrespective of the pulsation of the input voltage by controlling the series transistor having a parallel resistance by the transistor which is turned ON at more than a predetermined value of the pulsating voltage.  
     CONSTITUTION: When the pulsating voltage impressed between the input terminals 1 and 2 becomes large, the transistor 10 is apt to be OFF and the charging current to the battery 11 is made substantially constant. If the pulsating voltage is larger than the predetermined value, the period of ON of the transistor 3 is lenghthened, causing the dropping time width of the collector current to be lenghthened. If the pulsating voltage exceeds a certain limit and is increased, the dropping of the collector current becomes much larger, however, the dropping time width is not increased, so that the collector current is decreased. In order to correct the present reduction of the collector current, the parallel resistance 12 is provided.

Title: Switching power circuit
Inventor: MAEJIMA YASUSHI
IPC: H02M3/28
Filed: 1995-04-20
Abstract: PURPOSE: To provide a small-sized switching power circuit which can improve power factor easily. CONSTITUTION: An inductance element L1 high frequency-operated by a switching element S1 is connected to an input circuit 2 so as to increase a conducting angle α of input current I1 and restrain voltage of a smoothing capacitor C1 from rising and dropping or ripple voltage ΔV from increasing. Since the conducting angle α of the input current I1 is increased, power factor can be improved and noise resulting from harmonic distortion can be suppressed. Since the voltage of the smoothing capacitor C1 will not rise and drop or ripple voltage ΔV will not increase, it is also possible to prevent output ripple voltage from increasing and facilitate the circuit design.

Title: Idle rotation control device of engine
Inventor: ISHIDA YASUHIKO
IPC: F02D37/02
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To control an idle speed in a target rotating speed with high responsiveness and with high accuracy even under air-fuel ratio control by correcting the ignition timing by calculating an air-fuel ratio correction value of fuel on the basis of the oxygen concentration when idling is under practice and the air-fuel ratio control is also performed. SOLUTION: When an engine 16 is operated, in an ECU 15, whether the present oxygen concentration is rich or lean is judged on the basis of output of an O2 sensor 21, and an air-fuel ratio correction value CFB is calculated according to an oxygen concentration deviation. When output of the O2 sensor 21 is put in a lean condition, since the CFB continues to increase, an injector pulse width is corrected on the basis of this CFB, and fuel is injected from an injector 10. Next, whether or not the engine is put in an idle condition is judged, and in the case of YES, an average value of the CFB per constant time is found, and a difference between values of the respective CBFs in a constant time and the average value, that is, an air-fuel ratio variation difference is found, and an ignition timing correction value is calculated from the ignition correcting air-fuel ratio derived from its value.

Title: Vibration type transducer
Inventor: IKEDA KYOICHI
IPC: G01L9/00
Filed: 1990-05-10
Abstract: PURPOSE:To prevent a vibrating beam from attaching to a shell wall even if disturbance such as impact or buckling is applied and realize a complete transducer for eliminating disturbance by providing a coarse surface on the wall surface on the shell side so that the vibrating beam is not attached to a wall face of a vacuum chamber. CONSTITUTION:A coarse surface 11 is provided on a wall surface on a shell 4 side of a vacuum chamber 5.

Even if the vibrating beam 3 is in contact with the wall surface of the vacuum chamber 5 due to disturbance such as impact or buckling, existence of the coarse surface 11 prevents the vibrating beam 3 from attaching to the wall surface of the vacuum chamber 5 thereby eliminating the disturbance.
