Title: Dial device
Inventor: YOSHINO MOTOAKI
IPC: H04M1/27
Filed: 1992-01-28
Abstract: PURPOSE:To realize an optimum automatic redial control in accordance with each operation mode by changing the number of times of redial at the time of the transmission by a one easy step dial, etc., and at the time of the transmission by a ten keys dial. CONSTITUTION:A main control part 1 makes the number of times of redial be different when a dialling is performed by calling the telephone number stored preliminarily in a RAM 7 and when the dialling is performed by inputting the telephone number by the ten keys of an operation part 5 without using the telephone number stored preliminarily in the RAM 7. Thus, by setting various kinds of parameters regarding an automatic redial separately at the time of the transmission of a one easy step dial or an abbreviated dial and at the time of the transmission of the ten keys dial, an optimum automatic redial control in accordance with each operation mode can be realized. Therefore, when there is no possibility of the communication by the mistake of the input of telephone numbers, etc., the unnecessary repeating of redialling can be prevented.

Title: Receptacle
Inventor: MATSUSHITA TOKUO
IPC: H01R13/64
Filed: 1988-01-22
Abstract: PURPOSE:To confirm the excitation state by performing the visible display based on the display control signal from the detection circuit of the excitation state. CONSTITUTION:An excitation state detection circuit 3 detects the voltage fed from a commercial power source 1 and output the display signal 5. A display unit 4 activated by the signal 5 performs the visible display. When the circuit 3 detects no voltage, no signal 5 is outputted, thus the display unit 4 performs no visible display. The excitation state can be easily confirmed accordingly.

Filed: 1983-01-28
Abstract: PURPOSE:To keep a locked frequency normally even if an input signal is distorted by a noise by using an AND circuit, a thyristor and a chattering preventing circuit. CONSTITUTION:Suppose that a frequency of a PLL circuit is locked by an input signal without noise and then the input signal is distorted due to any cause, the locked signal 5 and the input signal 4 having the noise are applied to the AND circuit 9.

Abstract: PROBLEM TO BE SOLVED: To control fuel pressure on the injection valve side so as to improve the reliability by relieving fuel discharged from a fuel pump on the suction side using a normally closed solenoid valve. SOLUTION: Fuel in a fuel tank 1 is discharged into a low pressure pipe 3 from a low pressure pump 2.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To sufficiently eliminate a noise signal and to reduce signal distortion that is caused by mixture of a desired signal to a reference microphone. SOLUTION: This device has a signal-to-noise power ratio estimating circuit 10 which receives a main signal and a reference signal, estimates mean power of a desired signal in the main signal and a signal-to-noise power ratio of the main signal from mean power of a noise signal and also estimates mean power of a desired signal in the reference signal and a signal-to-noise power ratio of the reference signal from the mean power of the noise signal. Here, the step size of coefficient renewal of an adaptive filter 3 that estimates the noise signal in the main signal is controlled by the estimated signal-to-noise power ratio of the main signal. The step size of coefficient renewal of an adaptive filter 6 that estimates a desired signal in the reference signal is controlled by estimated signal-to-noise power ratio in the reference signal.  Delay circuits 8 and 9 compensate time delay that is caused by a power equalizing operation when the circuit 10 calculates an estimated value of the signal-to-noise power ratio.

CONSTITUTION:A heat-exchanger 13 which is arranged in an indoor unit 1 consists of a longitudinal part which extends in the approx. longitudinal direction, diagonal part 13B which diagonally tilts to the back surface side of a main body from the upper part of the longitudinal part, and a back surface part 13C which extends to the lower side of the back surface from the upper part of the diagonal part 13B. Respective heat-exchanger parts are constituted of a plurality of heat-transfer fins 13D and heat-transfer pipes 13E which pass through the fins. In this case, a gap dimension between a cross flow fan 20 which is arranged on the back surface side of a heat-exchanger of the longitudinal part 13A, and a drain pan 14 is formed to be larger at the end side than at the central side. By this method, a pressure at the end side is suppressed, and made closer to a pressure at the central side, and a pressure difference between the end side and central side of the cross flow fan 20 is made smaller, and thus, noise are reduced.

Abstract: PURPOSE: To prepare α-oxyisobutyric acid useful as a raw material of methacrylic acid, in high yield, by reacting acetone cyanhydrin with specific amounts of sulfuric acid and water, and hydrolyzing the reaction product.  
     CONSTITUTION: 1mol of acetone cyanhydrin is made to react with 0.5W2.0mol, pref. 0.9W1.2mol of sulfuric acid and 0.2W1.0mol, pref. 0.4W0.6mol of water.

Filed: 1987-01-23
Abstract: PURPOSE:To prevent adverse effect on a device due to the increase of the amplification degree of a call signal reception circuit from being given, by connecting the input terminal of a call signal reception means to one end of the secondary winding of an interface transformer, and connecting the input terminal of a transmission/reception circuit including an antisidetone circuit to the other end. CONSTITUTION:The ratio of impedance when a speech path is observed from the secondary side of the interface transformer 22 to the impedance of an impedance circuit network 27 is set so as almost to be equal to the ratio of the resistance value of a resistor 29 to that of a resistor 28. Therefore, most of transmission signals are negated with each other at the input terminal of a receiving amplifier 31, and are damped, then, a sidetone is suppressed. Therefore, even by decreasing the value of the resistor 29 being connected to the emitter of a transistor 25 to increase the amplification degree of a transmission system and according to that, decreasing the value of the resistor 28, a problem to increase noise affected on the device can be prevented from occurring. It is because that the input terminal of the call signal reception means 23 is connected to a power source terminal since the contact of a hook switch 35 is connected to a (b) side in an off-hook state.
