Inventor: KANAMORI TAKEO
IPC: H04R3/00
Filed: 1995-01-09
Abstract: PURPOSE: To improve the sound quality by reducing wind noise or vibration noise of a close-talking microphone. CONSTITUTION: First and second ominidirectional microphones 11, 12 and a voice/non-voice detection means 30 receiving an output signal from the ominidirectional microphones and detecting the voice signal or the non-voice signal are provided. When the signal is a non-voice signal, a noise level is estimated from an output of the 2nd microphone 12 and the output is amplified depending on the noise level. Then an output of a variable signal amplifier means 50 is subtracted from an output of the 1st ominidirectional microphone 11. Thus, the directivity is changes as double directivity in the case of high noise level and ominidirectional directivity at a low noise level. Thus, stable sound quality is obtained with immunity to wind noise and vibration noise at the low noise level.  Furthermore, fluctuation in the sound pressure frequency characteristic due to the magnitude of the wind noise and the vibration noise and the distance up to a sound source being a defect of the close-talking microphone is improved.

SOLUTION: In the case that transmission fails, a main control part 3 informs a judgement part 2 of an error code. The judgement part 2 compares the error code registered in a re-calling inhibition table 1 with the error code informed from the main control part 3 by communication result informing (b), informs the main control part 3 of the operation instruction (d) of not requiring a re- calling processing in the case that both match and informs the main control part 3 of the operation instruction (d) of requiring the re-calling processing in the case that they do not match. Only when the operation instruction (d) indicates that the re-calling processing is required, the main control part 3 executes the re-calling processing. For the re-calling inhibition table 1 for deciding the propriety of re-calling, corresponding to the operation of a system, the error code of not requiring re-calling is arbitrarily added or eliminated from an editing part 4.

Title: Rotation brake device for reel for feeding electrode for wire electric discharge machine
Inventor: AZUMA IZUMI
IPC: B23H7/10
Filed: 1991-01-21
Abstract: PURPOSE:To hold the tension of an electrode at a constant value during electric discharge or to perform useless brake operation during disconnection of the electrode by regulating the rotation brake force of a reel according to an unwound amount of an electrode under winding around the reel. CONSTITUTION:When an electrode P is consumed owing to electric discharge and an amount of an electrode remaining at a reel 1 is reduced, a remaining amount detecting rod 42 is inclined toward the reel 1 side, and a slider 45 is rotated through a transmission device 47. In which case, a voltage dropped by an amount, equivalent to the position of the slider 45 of a variable resistor 44, from a voltage V1 is inputted to an amplifier 48. As a result, an input to a rotation brake BL is decreased, a rotation brake force on the reel is reduced, and a tension exerted on the electrode P is held at a constant value. Since, during disconnection of the electrode, brake is carried out by means of a reduced rotation brake force, useless brake is prevented from application.

Title: Storage document erasure system for successive transfer facsimile equipment
Inventor: KARIBE MUTSUHIRO
IPC: H04N1/32
Filed: 1990-01-31
Abstract: PURPOSE:To erase picture information stored in a picture memory in a proper timing without causing waste of communication charge and time by providing means for erasing picture information stored in a picture memory of its own station to a request source through the reception of a transfer end notice. CONSTITUTION:A remaining transfer destination discrimination section 14 detects it that its own station is a final transfer destination based on the discrimination as to whether a transfer destination dial remains in a destination information storage section 12 or as to whether reception finished information is added to all of transfer destination dials and informs the end of transfer to the request source. Upon the detection of a transfer end notice sent from the final transfer destination, a dial erasure section 15 outputs a picture information erasure command to a picture memory 2. Thus, when a request station keeps the picture information, the picture information is kept for a required minimum holding time till the picture information is transferred to all the transfer destinations and waste of holding the picture information longer than the required time is avoided.

IPC: F02D41/14
Filed: 1988-02-01
Abstract: PURPOSE:To avoid reduction in fuel consumption ratio and improve the stability of idling operation by setting the cramping point of an compensatory air-fuel ratio feedback value at the time of the idling time according to the temperature of an engine. CONSTITUTION:When a control unit 14 decides that the condition where the air-fuel ratio feedback compensatory coefficient is to be cramped is satisfied, said unit 14 retrieves and finds the cramping value corresponding to the temperature of cooling water detected by a water temperature sensor 18 on the basis of a map in advance stored according to the temperature of cooling water. The cramping value is stored that it is increased over the reference value when the temperature of cooling water is lower. Thus the temperature of cooling water is able to be controlled suitably according to each temperature of cooling water so that the reduction in fuel consumption ratio may be avoided and the idling operation at each temperature of cooling water be stabilized.
