Patent JP-H0758650-A (JP)
Title: Noise canceller
Inventor: FUJIWARA KOJI
IPC: H04B1/10
Filed: 1993-08-16
Abstract: PURPOSE:To reduce the quantity of remaining noise by inserting an attenuator to the non-inverted input side of a trans-conductance amplifier from the output side of a limiter amplifier to sharpen the fall of the differential waveform outputted from the limiter amplifier. CONSTITUTION:An LPF 15 corrects the phase of an inputted signal VB to make it coincide with the phase of an input signal Vin. A signal VC after phase matching is outputted. At this time, the signal VC has a part where the noise component does not exist, but the time width of this part is shorter than conventional. A subtractor 7 takes the input signal Vin from the + input terminal and takes in the signal VC from the-input terminal and outputs a difference VO(=Vin-VC) between them. Since the signal VC has the part where the noise component does not exist, the part where noise is not eliminated remains in the signal VC. The time width of this part is shorter than conventional. Consequently, the fall of the waveform from the limiter amplifier 14 is sharpened by provision of an attenuator 19.

Title: Image remote observation system
Inventor: NAGATA HIROSHI
IPC: H04N7/18
Filed: 1992-07-29
Abstract: PURPOSE:To enable an efficient, economical remote observation of a microscopic still image. CONSTITUTION:When an image for observation is transferred to observation terminal equipment 101, the CPU 52a of microscopic terminal equipment 100 switches to a transmission buffer 55a a mouse buffer 53a for controlling a menue screen 51a located at the terminal of the CPU. After reception of the still image from the microscopic terminal equipment 100 has been completed, the CPU 52b of the observation terminal equipment 101 transmits the contents of the mouse buffer 53a to a reception buffer 56a via the transmission buffer 55b. Further, when the CPU 52a switches the mouse buffer 53a to the transmission buffer 55a of the microscopic terminal equipment 100, at the observation terminal equipment 101 the CPU 52b transmits the contents of its mouse buffer 53b to the reception buffer 56a and executes on the menue screen 51b of the microscopic terminal equipment 100 the same operations as those on the menue screen 51a of the observation terminal equipment 101.

Title: Transversal filter
Inventor: MINAMI SHIGENOBU
IPC: H03H15/00
Filed: 1983-10-31
Abstract: PURPOSE:To provide many taps without decreasing the system efficiency by providing a shift register for at least one clock delay for the addition between units constituting a transversal filter. CONSTITUTION:Shift registers (SR) 401, 403, a data selector (DS)402 and a chip counter 404 are added newly so as to improve the addition of partial sum. A 1- clock delay 1-bit SR403 is inserted between input and output between units of a partial adder 205. Thus, the clock at partial sum is constant independently of the unit number L. The counter 404 consists of, e.g., a parallel adder 501 and a value more than the input data in a m-bit by 1 is outputted to an output terminal COUT. Thus, (i) is outputted in a binary number in m-bit at a counter output at the i-th chip. The DS402 receives it, the SR401 selects a data shifted by the i- stage among L sets of input data and the result is given to a terminal A of the adder 205. Thus, the data subjected to 1-clock shift is fed to an ADD.A terminal in the unit 1 and synchronized with the input ADD.B from the pre-stage.

Title: Fault information recording system
Inventor: YAMAMOTO YUJI
IPC: H04M3/22
Filed: 1994-08-29
Abstract: PURPOSE: To facilitate analysis of fault information through reading of the fault information by storing connection information and service information as the fault information. CONSTITUTION: For dialling from an extension telephone set 3, dial information is stored in an A area 121 through an extension telephone set interface 15 and a CPU 11 and transmission is performed through a trunk line interface 14 to a trunk line 2. When dial transmission from the telephone set 3 is ended, the telephone set 3 is connected to a callee. When a fault is generated in the middle of a call, a fault command is transmitted from the telephone set 3 which encounters the fault to the CPU 11 by a functional key operation. The CPU 11 reads the connection information and service information of the telephone set 3 from the A area 121 and stores and holds them in a B area 122 as the fault information. Then, by a fault information output operation, the fault information is outputted from the B area 122 to an output device 4.  Thus, even when the information of the other call substitutes for the information stored in the A area 121 and eliminates it, the fault information is stored and held in the B area 122 and utilized without being eliminated.
