Title: Formatin of metallic coating layer on surface
Inventor: HASHIMOTO KOUJI
IPC: B23K26/34
Filed: 1984-05-12
Abstract: PURPOSE:To form easily a uniform metallic coating layer in optional composition on the surface of a substrative metal by placing a thin metallic plate having specified properties on the surface of a substrative metallic material, and irradiating the plate with a high-energy density beam while controlling the energy density and irradiating time. CONSTITUTION:A thin film of an Fe-Cr-Ni-P-C alloy in 20-30mum thickness is placed on an Ni plate as a substrative metal, and liquid paraffin is interposed in-between. A high-energy density beam such as a laser and an electron beam is irradiated in a vacuum vessel to partially melt the alloy thin film, and a molten thin film of the alloy is formed while forming an alloy of both Ni and alloy between the substrative Ni and the alloy. Or the third metal which can be easily cemented to the surface of the substrative metal is previously plated on the surface of the substrative metal, the alloy thin film is placed thereon, and a beam is irradiated. The energy density and irradiation time are controlled, and an amorphous Fe-Cr-Ni-P-C alloy coating layer having excellent corrosion resistance, toughness, and strength is formed.

Title: Musical sound controller
Inventor: SUZUKI HIDEO
IPC: G10H1/18
Filed: 1989-04-13
Abstract: PURPOSE:To finely control a musical sound according to the fine action of a human body by reflecting a wave body outputted from plural wave body generating means provided at intervals by means of a part of the human body and his hat. CONSTITUTION:When a power source is turned on, and a desired sound quality is selected by the operation of the respective switches of a switch group 8, beams are successively emitted from respective light emitters 2 in units of several msec. Then a human being positions inside a musical sound control part 1, and holds a reflecting object such as his hands, legs or hat over the irradiation range of the specific light emitter 2 corresponding to the name of the musical sound (a pitch), and partially shades the beams from the specific light emitter 2. Thus a CPU 5 calculates musical sound control data to control the pitch or a vibrato, etc., corresponding to the relative position relation between the light emitter 2, which has emitted the beams, and a light receiver 3, which has received the beams. Consequently by suitably moving the reflecting body, the musical sound finely controlled to the desired pitch can be outputted from a sound system 12 through a tone generator 11.

Filed: 1986-04-23
Abstract: PURPOSE:To obtain a separated brightness signal whose signal components of frequencies between the frequencies integer-times of the half of the horizontal frequency within a prescribed band is emphasized by constituting the circuitry in a simple constitution requiring no special delay circuits other than a delay circuit for the signal- separation. CONSTITUTION:An input video signal Vi is supplied to a delay circuit 21 and delayed for two times of horizontal frequency. An output signal from the delay circuit 21 is subtracted from the input video signal Vi, an output signal from an subtraction circuit 22 is supplied to an attenuator circuit 23 where it is attenuated to the half, and an output signal from the attenuator circuit 23 is conducted to an output terminal 20c. Also, the output signal from the attenuator circuit 23 is subtracted from the input video signal Vi, and an output signal from a substraction circuit 24 is conducted to an output terminal 20y. Therefore, assuming the horizontal frequency of the input video signal Vi to be fH and the subc arrier wave frequency of the same to be fsc, the frequency characteristic between a video signal input terminal 10 and the output terminal 20c forms troughs of minimum gain at the frequencies integer-times of the half of the horizontal frequency through entire carrier color signal band and the lower side band.

Filed: 1985-05-01
Abstract: PURPOSE:To improve S/N by repeating an electricity conduction and an interruption in a fixed rate, extracting only a picture of a section for a fixed time which does not reach to a thermal equilibrium after the electricity conduction and integrating. CONSTITUTION:A signal TF is a frame signal of an analog video and added to the analog video.

Title: Recovering method for metallic titanium from titanium-grinding sludge
Inventor: KAWAGUCHI KAZUO
IPC: C22B34/12
Filed: 1980-07-08
Abstract: PURPOSE: To recover metallic Ti from titanium-grinding sludge as ferrotitaium by an effective and inexpensive method by cleaning the sludge followed by compression molding and dissolution in iron in an Ar atmoaphere.  
     CONSTITUTION: Titanium-grinding sludge discharged in a process of manufacturing a titanium plate contains much water and much oil and fat which lower the Ti recovering rate as an exygen generating source and invite the danger of exlosion when the sludge is added to molten iron. In addition, they increase the viscosity of molten ferrotitanium and remarkably hinder the ingot making work. Accordingly, the sludge is well degreased with a detergent or an org. solvent by means of a mixer, an ultrasonic washing machine or the like, dehydrated, and dried with warm air at ≤ about 300°C or by heating with an infrared lamp or in a vacuum so as to avoid the ingnition of chipped or powdered sludge due to intense heating. The sludge is then compression-molded to enchance the work efficiency, and a necessary amount of the sludge compact is added to iron melted in a melting furnace in an Ar atmosphere. After finishing dissolution the resulting molten alloy is cast in a mold quickly.

Title: Switching power unit
Inventor: KAMETANI KAZUO
IPC: H02M3/28
Filed: 1979-07-27
Abstract: PURPOSE:To prevent the generation of a spike voltage by connecting a subtransformer winding in parallel to the secondary winding of a main transformer. CONSTITUTION:A primary side series circuit is composed of DC power source E, a primary winding L1 of a main transformer T1, a collector and the emitter of a transistor TrQ1. The winding L12 of a subtransformer T12 is connected in parallel to a secondary winding L10 of the main transformer T1 and a connection point 8 is connected to a rectifying diode D10 and a smoothing circuit 3. With the transistor TrQ1 ON, current flows through the primary winding L1 to cause an induced voltage in the secondary winding L10 whereby energy is accumulated in the main transformer T1 and the subtransformer T12. With the transistor TrQ1 OFF, the energy is released to obtain an output from the terminal 4. However, because the accumulated energy is divided, the spike voltage generated in the main transformer can be reduced.

Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To increase the total input and output voltage ratio of a multiplex PWM cycloconverter by calculating the instantaneous value of output voltage command for the three-phase/single-phase PWM cycloconverter of a single unit depending on the difference between the maximum and minimum input power supply phase voltages and outputting the calculated instantaneous value. SOLUTION: Phase of the output voltage from three-phase/single-phase PWM cycloconverters 1-12 is controlled. Instantaneous value of output voltage command for the three-phase/single-phase PWM cycloconverters 2-12 of a single unit 17 (18, 19) is calculated to have a large value when the difference Δe between the maximum and minimum input power supply phase voltages is large otherwise to have a small value. Since a total input and output voltage ratio comparable to that of a multiplex PWM cycloconverter, the total input and output voltage ratio of a multiplex PWM cycloconverter can be increased and the size of system can be reduced.
