Patent JP-H01109908-A (JP)
Title: Frequency shift compensation circuit
Inventor: MASUDA ICHIRO
IPC: H03F3/00
Filed: 1987-10-23
Abstract: PURPOSE:To control the frequency deviation within the deviation standard over a wide range of frequencies by having only to set a maximum frequency deviation variable resistor at once only through the attenuation of a prescribed amount of an audio signal corresponding to the selected channel. CONSTITUTION:When the operating frequency channel is selected by a channel select section 5, a setting section 6 sets the frequency of a carrier to generate the carrier from a carrier generating section 4. Simultaneously, the setting section 6 sets variably the attenuation of an audio signal corresponding to the carrier frequency and an attenuation section 7 attenuates the signal by a prescribed quantity. ln setting the level by the attenuation section 7 so as to decrease a low frequency output level with respect to, e.g., the carrier frequency, the frequency deviation  f is nearly constant in any channel and the maximum frequency deviation of one channel is preset within the standard of the maximum frequency to eliminate the need for the succeeding adjustment.

Title: Method of controlling level of audio signal
Inventor: ROBAATO BII PURADETSUKU
IPC: H04N7/04
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To control an audio signal through an intended and desired effect by summing an audio signal and a stabilizing signal that has a level which prevents a signal level from arbitrarily increasing and forming a composite signal. SOLUTION: A sine wave generator 30 that is provided with a volume controller 31 generates a stabilizing signal 32 that has a level which prevents a signal level from arbitrarily increasing. An audio device 15 sums an audio signal 8 that is outputted by an audio recording and reproducing device 5 and the signal 32 and forms a composite audio signal. A recorder 25 records the composite audio signal on a recording medium 26. When a television broadcast facility broadcasts information recorded on the medium 26, the signal 32 is eliminated by limiting the frequency range of an audio signal to be outputted and the audio signal completely match the original signal 8. Because of this, the signal 32 stabilizes an audio signal in television broadcasting.

After connecting a line, the control part 13 outputs a read-out start signal S2 to a message memory 23 in accordance with the contents of the signal outputted from the sensor 15. Then a current position signal S4 is allowed to be outputted from an electronic map 12 and outputted to a voice synthesizing part 14 as a signal S3. The voice synthesizing part 14 converts the inputted signal S3 into a sound signal and outputs the sound signal to a voice/signal conversion part 24 in the telephone set 11.

Title: Image recorder
Inventor: NAKADA YASUHIRO
IPC: G03G15/20
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To effectively suppress a malfunction caused when serge noise applied to a commercial AC power source arrives at a processor because a heating element and a thermistor is coupled through a capacitor not by directly connecting the GND of the thermistor side to the GND of the processor but by connecting it to the GND of the commercial AC power source and a nearer metallic housing in terms of potential. SOLUTION: The commercial AC power source is supplied from a power source connector INLET. Then, the FG (metallic housing) is connected to the halfway point of a line (circuit) preceding to the lower SG of a processor CPU from the upper terminal of the thermistor TH. The serge noise inputted from the commercial AC power source and inputted to the thermistor TH from the heating element H by the coupling through the capacitor escapes toward the GND of the FG (metallic housing) to which the GND line of the commercial AC power source is connected without through the SG being the GND of the processor CPU. As the result, the malfunction of the processor CPU caused by the serge noise is prevented from occurring.

Abstract: PURPOSE:To surely melt-bond a strap and a lug and to prevent circular narrowing in the root of the lug by forging the lug of a plate so that the lug becomes gradually thin toward the tip, and by immersing the narrowed part of the lug into molten lead to form the strap. CONSTITUTION:A lug 2a of a plate 2 is formed so that the lug 2a becomes gradually thin toward the tip. Since the melting point of the forged lug is decreased compared with that of a nonforged part, temperature condition in production is widened, and a strap 6 and the lug 2a are surely melt-bonded. The plate 2 is lowered down and the lug 2a is immersed into molten lead 3 until the lower part 2b of the lug 2a is embedded to melt-bond the lug 2a with the molten lead 3. The strap and the lug are surely melt-bonded and circular narrowing in the root of the lug is prevented.

Abstract: PURPOSE:To easily update the content of a ROM by shifting the content of the ROM and updating the content of the RAM on the basis of ROM space content updating information stored in a backup RAM. CONSTITUTION:A ROM space access switching mechanism 2 brings a memory protective mechanism 4 into a write enable state to a RAM 5 under the control of a CPU 1 and the content of a ROM 3 is copied to the RAM 5.
