Title: A sound reverberator device for detachable connection to the strings of a string musical instrument
Inventor: ASPRI ROBERTO
IPC: G10D3/02
Filed: 1988-05-28
Granted: 1997-06-13
Abstract: A sound reverberator device (10) for detachable connection to the strings (12) of a string musical instrument (11) which has strings (12) tensioned over a bridge piece (13) connected to the top wall of the sound box (15) or the instrument (11). The reverberator (10) comprises three spaced apart metal coil springs (17) secured side-by-side at a common end to a spring support (19). A metallic string attachment member (21) is secured to a free end of each of the springs. The attachment member (21) has string engaging fingers for engaging a respective one of a pair of adjacent strings (12) of the musical instrument (11). The attachment member (21) further has a bridge abutment portion (29) for contact with the bridge piece (35). When the reverberator (10) is connected to the musical instrument (11), the springs (12) are tensioned with the attachment member (21) connected to the strings whereby vibrations imparted to the strings will be transmitted to the bridge piece and the associated spring. The spring (17) will then vibrate and transmit its vibrations to the sound box through the bridge piece whereby to modify the tonality sound generated by the sound box.

Abstract: PURPOSE: A dual signal processing circuit is provided to selectively output the output of a local circuit by using a method, which separately includes a signal processing board and a preliminary signal processing unit and selects the other upon the occurrence of a defect in one signal processing unit; and a method, which includes circuits having a part of processing a critical signal or a faulty part and selects the other upon the occurrence of a defect in one local circuit using a multiplexer. CONSTITUTION: A first signal processing unit receives a first and a second input signal and performs a predefined signal processing on the received signals to produce a third output signal. A second signal processing unit receives the first and second input signals and performs the predefined processing on the received signals to produce a second output signal. An output selecting unit selects one of the second and third output signals, and automatically selects the other upon the occurrence of a defect in a selected signal processing unit for the output of the signal.

Abstract: 본 발명은 구내 무선전화 시스템에 관한 것으로서, 특히 휴대 장치가 통화중일 때 휴대 장치가 알 수 있도록 하기 위하여 착신측 휴대장치의 표시부(LCD)에 호출자의 휴대장치 고유번호(ID)를 서브톤(SUBTONE) 주파수를 이용하여 통화중 걸려 온 휴대장치 번호를 표시해 주도록 하는 구내 무선전화 시스템에 관한 것이다. 
     본 발명은 구내 무선전화 시스템 제어장치(3)와 연결된 다수의 고정장치(2a∼2d) 중 어느 하나를 통해 다수의 휴대장치(1a∼1d)간에 구내 무선전화를 하기 위한 구내 무선전화 시스템에 있어서, 상기 각 고정장치(2a∼2d)는 제어부(12)의 지시에 따라 상기 제어장치(3)로부터 수신한 휴대장치의 고유번호에 대응하는 서브톤 주파수를 발생하여 송신부(5)로 출력하는 서브톤 발생기(A)를 더 포함하여 구성되고, 상기 각 휴대장치(1a∼1d)는 수신부(84)를 통해 수신한 상기 서브톤 신호로부터 서브톤에 대응하는 데이터를 검출하여 제어부(81)로 출력하는 서브톤 검출기(B)를 더 포함하여 구성되며, 통화중에 있는 상기 어느 하나의 휴대장치에 상기 다른 어느 하나의 휴대장치가 통화를 시도하는 경우 상기 제어장치(3)는 상기 통화를 시도한 휴대장치의 고유번호에 해당하는 데이터를 통화중인 휴대장치와 연결된 고정 장치로 전송하며, 상기 고유번호를 수신한 고정장치는 상기 서브톤 발생기(A)에 의해 수신한 고유번호를 수신한 고정장치는 상기 서브톤 발생기(A)에 의해 수신한 고유번호에 대응하는 서브톤을 발생하여 상기 송신부(5)를 통해 통화중인 휴대장치로 송신하여, 상기 통화중인 휴대장치는 상기 서브톤 검출기(B)에 의해 검출된 서브톤에 대응하는 데이터 값을 상기 제어부(81)에 의해 전화번호로 바꾸어 표시부(86)를 통해 표시해 준다.

Abstract: Disclosed is an apparatus to improve typing quality of a non-impact type printer.  The apparatus comprises input buffers(100, 110), a data arrangement and movement means(120), a decision-window forming means(130) and a comparing module(140).  The input buffers(100, 110) store parallel image data converted from the serial input image data.  The data arrangement and movement means(120) arranges and moves the parallel data from the input buffers(100, 110) according to the image clock signal VDOCLK, The decision-window forming means(130) forms a decision-window for comparing according to the output data from the data arrangement and movement means(120).  The comparing module(140) compares the decision-window with a reference window, and decides whether a transforming is necessary or not.  Thereby, font control is precisely controlled and the typing quality is improved.
