Patent JP-H07273569-A (JP)
Title: Audio signal power amplifier circuit and audio equipment using the same
Inventor: NISHIOKA KEI
IPC: H03F3/213
Filed: 1994-03-30
Abstract: PURPOSE:To improve the power utilizing efficiency by providing a switching control circuit and a switching circuit between an amplifier and a power supply line or a ground line and setting either of push-pull outputs for each half cycle. CONSTITUTION:A comparator 44 applies an input audio signal B to a noninverting input and a Vcc/2 reference voltage is applied to an inverting input and provides an output of a pulse signal T corresponding to an upper half cycle of the signal B. The signal T is fed to a base of a transistor(TR) Q4 and inverted by an inverter 45 and the inverted signal is fed to a base of the TR Q2. Either of the pull-side TRs Q2, Q4 is set for each half cycle of the signal B and one terminal of a speaker 4 reaches a voltage higher than a ground level by a collector-emitter voltage of the TR when it is conductive. Thus, a current flowing to coils L70, L71 is commutated respectively via diodes D70, D71 when the switching is released respectively. In this case, since the commutated current does not flow the ground, the voltage is made stable and the power consumption is reduced by the commutated current not via the ground line.

Title: Surface modified magnesium alloy
Inventor: NAKANISHI MASAJI
IPC: C25D11/30
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance of a magnesium alloy by coating the surface of a magnesium alloy with a material which reacts with water to have alkalinity. SOLUTION: The surface-modified magnesium alloy 1 having a coating material which reacts with water to have alkalinity on its surface consists of a magnesium alloy 2, an anodized film 3 having pores with openings on its surface on the magnesium alloy 2, and an alkali layer (NaOH layer) 4 on the anodized film 3 having pores. Since the surface-modified magnesium alloy consists of a magnesium alloy coated with the material which reacts with water to have alkalinity, even when an acidic substance such as rain water reaches the surface of the magnesium alloy, the substance which have alkalinity neutralizes the acidic liquid to render the liquid into harmless for the corrosion of magnesium. Further, by forming a ceramic layer containing P on the alkali layer 4, dropping of the alkali layer 4 and diffusion of alkali ions can be also prevented, which further improves the corrosion resistance.

Abstract: PURPOSE:To optimize the dielectric strength and other characteristics of each of the elements formed on the same substrate, by forming separating layers which surround one element as well as have a depth larger than at least that of a layers, at an interval. CONSTITUTION:On an N type silicon substrate 1, an N type epitaxial layer 2 is formed, and a P type lower surface-separating layer 3 to separate a small signal transistor (Tr), and a floating collector 4 are formed therein. Moreover, a low- concentration N type epitaxial layer 5 is formed thereon. When a base 6 of a power transistor and separating layers 7 and 8 of the small signal transistor are to be formed, simultaneously, guard ring layers 17 and 18 are formed so as to surround the periphery of the base 6 as well as reach at least the layer 2, at an interval. Owing to said separating layers 17 and 18, the field strength at this partion becomes weaker than that beneath the base, so that breakdown takes place mainly beneath the bases 6 and 12.
