Title: Acoustic device
Inventor: NAKAO YOSHIKAZU
IPC: H03F3/181
Filed: 1983-12-06
Abstract: PURPOSE:To simplify a mixing circuit and to reduce the cost by inputting an acoustic signal to the plus input terminal of a differential amplifier which has a negative feedback signal at the minus input terminal and a microphone output signal to the negative input terminal and mixing them with each other. CONSTITUTION:The acoustic signal from a radio reception part 2 which is selected by a changeover switch 21 or from acoustic signal of a record or tape from a terminal 4 is supplied to the plus input terminal 8 of the differential amplifier 6 of an amplifier circuit part 5. When a microphone plug is inserted into a microphone signal input terminal 15, the output of a microphone signal amplifier 17 is floated from the earth side by a switch 20 associatively and the microphone signal from the amplifier 17 is supplied to the minus input terminal 9 of the amplifier 6 through a buffer resistance 18. The output signal of the circuit part 5 is fed back to the terminal 9 through the negative feedback circuit 11 to flatten the frequency characteristics of the acoustic signal. The acoustic signal and microphone signal are mixed by the circuit part 5 and outputted from a terminal 19. When the microphone plug is not inserted into the terminal 15, the switch 20 grounds the output of the amplifier 17 to prevent the mixing with the acoustic signal.

Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To provide a telephone device and a hooked state detecting method for detecting the hooked states of telephone sets connected in parallel even when the telephone device is in on-hook state or off-hook state without increasing costs. SOLUTION: The line voltage is converted into the dynamic range of an OP amplifier, and a signal is inputted to a comparator circuit 3 with a triangular wave. The output waveform of the comparator circuit 3 is turned into a pulse waveform, and when the voltage of the line is changed, the width of the pulse waveform outputted from the comparator circuit 3 is changed. Thus, the hooked states of the telephone sets connected in parallel can be recognized even with an inexpensive control part (CPU) 4 without an A/D converter.

IPC: H01S5/00
Filed: 1987-09-14
Abstract: PURPOSE:To enhance light-emitting efficiency by a method wherein a non- diffusion region whose interface facing a resonator direction functions as an internal reflector is formed at least in one part of a diffusion region of an impurity of a second conductivity type constituting a refractive-index guide mechanism diffused to be a stripe shape along the resonator direction inside an active layer.

Then, a mask 10 having an opening and composed of, e.g., Si3N4 is formed; then, Zn is diffused from the opening; a P-type diffusion region is formed. During this process, a non-diffusion region 9 is formed under a central part 11 between openings of the mask 10. By this setup, a transverse mode is stabilized by a refractive-index guide mechanism. In addition, a difference in a refractive index at a p-n junction of an interface facing a resonator direction of the P-type diffusion region 7 and the non-diffusion region 9 inside the active layer 3 functions as an internal reflector; accordingly, mode hopping is not caused due to an effect of internal reflection interference and an axis mode is stabilized.
