Abstract: PROBLEM TO BE SOLVED: To prevent heat from concentrating on the transistors of a power output stage by generating low power voltage when the sound volume of a speaker is small, generating high power voltage when the sound volume of the speaker is large and supplying it to a power output part. SOLUTION: An input signal AS1 which is level-adjusted is voltage-amplified in a preamplifier 11 and is supplied to the bases of the transistors Q11 and Q12 of the power output stage. The input signal which is voltage-amplified is power-amplified in the transistors Q11 and Q12 of the power output stage and is outputted to the speaker SP as output voltage Vo. Power voltage ±Vc is generated in variable power sources 12A and 12B, and it fluctuates in cooperation with the resistance value of a volume VR0. Namely, low power voltage ±Vc is generated when the sound volume of the speaker is small and output voltage Vo is low since the resistance value of the volume is large, and high power voltage ±Vc is generated when the sound volume of the speaker is large and output voltage Vo is high since the resistance value of the volume is small.

Title: Manufacture of nozzle plate for ink jet
Inventor: MIYASAKA YOSHIYUKI
IPC: B41J2/135
Filed: 1990-10-04
Abstract: PURPOSE:To obtain procedures for manufacturing a nozzle plate for ink jet capable of high print quality with superior nozzle hole diameter accuracy by patterning with a metal film for forming nozzle holes and also patterning with a photoresist for controlling the diameter of nozzle holes in the center of the pattern with the metal film. CONSTITUTION:A Cu metal film is formed on a substrate 1 consisting of a non-metal material. Next, a photoresist 3 is applied using a spin coater. After that, the photoresist 3 is patterned in the form of a nozzle plate. Then the metal film 2 is patterned using etching technique. Further, the photoresist 3 is peeled apart to be followed by the application of a photoresist 4. Following these procedures, the photoresist 4 is patterned to the specified nozzle hole diameter in the center of a nozzle hole formed with a metal film 2 using patterning technique. Then, electrolytic nickel plating or electroless nickel plating is performed to build thickness until the tip of a plated film reaches the photoresist 4. Thus a nozzle plating is achieved, after which the nozzle plate 5 is removed from the substrate 1 using mold parting technique. The obtained ink jet nozzle plate allows a high-accuracy nozzle hole to be made and ink droplets of stable particle size to be discharged.
