Title: Electrically conducting rool alloy for electroplating
Inventor: ISHII TOSHIAKI
IPC: C25D7/06
Filed: 1987-02-10
Abstract: PURPOSE:To improve hardness and electro- and mechanical-corrosion and wear resistance, by specifying the component compsn. of a 50Cr-50Ni alloy. CONSTITUTION:This alloy consists of 40-55% Cr, 2-10% Mo, 0.01-0.2% B, <=1% Si, <=1% Mn, <=10% Fe, <=0.1% C, <=0.2% N, and the balance Ni or contains >=1 kinds among 0.5-2% Nb, 0.5-3% Ta, 0.1-1% Ti, 0.1-1% Al, and <=2% V at need further in said alloy and consists of the balance Ni. Mo in said compsn. is extremely effective in improving the corrosion resistance of the 50Cr-50Ni thermal aging alloy and is, therefore, added at >=2% to the alloy, but the alloy is embrittled if said element is added at 10% or over. B strengthens the grain boundary, prevents the grain boundary crack and strengthens the electric corrosion resistance and is, therefore, added at >=0.1%, but toughness, etc., are impaired if added at 0.2% or over. Fe is economically advantageous when added to the alloy so as to co-exist therein but causes the deterioration in the material quality when added to 10% or over. Si drastically decreases the ductility and weldability after thermal aging at 1% or over. Mn degrades the ductility at 1% or over.

Filed: 1995-02-17
Abstract: PURPOSE: To continuously produce a purified long silicon ingot in good productivity by continuously solidifying melted metal silicon in a direction to concentrate impurities in a liquid phase, and subsequently discharging the concentrated liquid phase from a mold. CONSTITUTION: A silicon rod 7 containing impure elements is thermally melted with electron beams 9 from an electron gun 1 at a place above a water-cooling copper mold 2, and the melted product is dropped into the water-cooling mold 2. When the dropped melted silicon 9 is gradually lowered with a lowering device 4, the melted silicon 9 is solidified in a direction from the lowest part to the upper direction to given silicon ingot 3. The impure elements are concentrated in the non-solidified melted silicon 9. When the concentration of the impure elements in the silicon liquid phase or in the solid phase reaches a target value, the melting of the silicon rod 7 and the lowering of the ingot 3 are stopped, and the melted silicon 9 in the upper part of the water-cooling mold 2 is discharged from a discharging opening 5 into a receiver 6.  Subsequently, the silicon rod 7 is again melted, and the lowering of the silicon ingot 3 is again continued.

Title: Howling suppressing and preventing system
Inventor: AIDA YOSHIO
IPC: H04R3/02
Filed: 1983-02-25
Abstract: PURPOSE:To improve speech quality and suppress and prevent howling by making sensitivity of microphone amplifier normal when the sound is decided as speaker's voice by a deciding device, and lowering sensitivity of the microphone amplifier automatically when the sound is judged as sidetone. CONSTITUTION:Speaker's voice to a microphone 1 is outputted through a resistance R1 amplified by an amplifier 32. At this time, output of the amplifier 32 is inputted to an arithmetic amplifier 30 and compared with comparison voltage Vr2. When DC voltage is greater than the comparison voltage Vr2, output of the arithmetic amplifier 30 becomes negative level. When sensing level to the microphone 1 is low level such as indoor noise, DC voltage V0 is smaller than comparison voltage Vr2 and output of the arithmetic amplifier becomes positive level. FET31 is short-circuited, and signal from the microphone 1 is not outputted. A controller 28 decides whether the sound is sidetone due to spreading into the microphone through speakers 13, 14. When it is decided as speaker's voice, loss of automatic loss adjusters 24, 25 is made almost zero, and when it is decided as sidetone, loss of automatic loss adjusters 24, 25 are controlled to become larger automatically.

The illumination light projected onto the surface of the sample SA is set with a high incident angle at an angle adjusting section 5. The high incident angle means an incident angle to the surface of the sample SA exceeding about 45 deg.. Open angle of the illumination beam incident to the surface of the sample SA is adjusted smaller than ±3 deg. by means of a beam shaping optical system 41, a lens system 44, and the like. Regular reflection light from the sample SA is subjected, as a detection light, to photoelectric conversion by a photomultiplier tube 64.

Title: Banknote saturation detecting method in banknote handling device
Inventor: MATSUZAKA KOUJI
IPC: G07G5/00
Filed: 1978-03-15
Abstract: PURPOSE: To detect the saturation of banknotes in a containing box based on the relative position relations of a moving body and a detecting piece.  
     CONSTITUTION: When the banknotes in a containing box approach to their saturation, a contact piece 59 goes closer to a photoelectric detector 60 and when the detecting piece 59 retreats during the forcing operation of the banknotes, it cuts off the projection light of the photoelectric detector 60. As a lever 55 advances owing to forcing operation, the light is cut off by the portion 55b of the lever 55 positioning closer to its rear end than through-hole 57. When the lever 55 returns to its original position, the light is again cut off by the portion 55b. In the end, the projection light of the photoelectric detector 60 is cut off twice by the lever 55 through one forcing operation irrespective of whether the banknotes in the containing box 40 are less or saturated.

IPC: G01R31/02
Filed: 1984-02-21
Abstract: PURPOSE:To correct change of power source voltage and enable stable abnormality detection by giving reference voltage to the first and second transistors (TRs) controlled by voltage that changes according to the state of a line, etc. from a common voltage dividing circuit. CONSTITUTION:When input resistance R is normal, a TR 11 becomes off state and TRs 12, 13 become off, and output is not generated in an output terminal C. When input resistance R becomes short-circuited state, a voltage of point A becomes 12V. The TR 11 becomes on and TRs 12, 13 become on, and output is generated in the output terminal C through a gate IC 14. When input resistance R is infinity  (open state), if R2<<(R1+R3) the TR 11 becomes off and an emitter voltage of the TR 12 becoms about 8V. Because (R1+R2) R3, a base voltage of the TR 12 becomes about 6V. TRs 12, 13 become on and output is generated in the output terminal C. As reference voltage changes in the same rate when power source voltage changes, stable detection can be made.
