Title: Echo elimination circuit
Inventor: KOYAMA TORU
IPC: H04B3/23
Filed: 1989-05-31
Abstract: PURPOSE:To suppress an echo signal and to accelerate convergent speed at the time of suppressing an echo by using a gain control signal in which a tap is multiplied by the optimum correction coefficient at every tap corresponding to the degree affected on a residual echo. CONSTITUTION:A transversal filter 2 is comprised in a circuit in which the correction coefficient is separated to two or more, and the gain control signal in which the taps (x) and (y) are multiplied by the optimum correction coefficient at every tap (x) and (y) corresponding to the degree affected on the residual echo is used. In other words, the transversal filter 2 is comprised so that the tap (x) with the large level of a residual echo signal is multiplied by a large correction coefficient alpha1, and the tap with the small level of the residual echo is multiplied by a small coefficient alpha2, respectively. At such a case, the convergent speed can be increased by increasing the correction coefficient, however, the residual echo signal is increased, therefore, the convergent speed is accelerated by using two correction coefficients alpha1 and alpha2, and also, the level of the residual echo signal can be decreased. Thereby, the echo signal can be suppressed, and also, an echo elimination circuit with fast convergent speed can be obtained.

Abstract: PURPOSE:To manufacture a mask frame precisely and rapidly damp the vibration of a shadow mask by securing it to the cylindrical surface of a curving member in the tensioned condition, and stretching a damper wire on the fluorescent surface side of the shadow mask in such a way as tightly attaching it. CONSTITUTION:By processing with a press, a mask frame 12 is single-piece shaped into the form of a rectangular frame, whose frame surface lies on one plane. The flat portion of each of a pair of crosswise extending. mutually mating frame edges of this mask frame 12 is fitted with a curving member 13, wherein the surface on the side contacting a shadow mask 11 constitutes a cylindrical surface protruding being curved toward the fluorescent surface with a large radius centering on a longitudinal axis while the surface on the opposite side is flat. The mask 11 peripheries in the crosswise direction are secured while a pressure is applied so that the frame edges to which the curving member 13 is secured are approached to each other. Then a tension is given to the mask 11, and a thin wire for damping vibration with a certain pressure applied to the fluorescent surface side of the mask 11 is put in tight attaching to the mask 11 in the crosswise direction and is stretched over the frame 12 with a elastic member interposed.

IPC: G06V30/148
Filed: 1981-09-02
Abstract: PURPOSE:To accurately segment even mutually close characters by extracting pattern components which constitute the characters, and discriminating the position of every pattern component. CONSTITUTION:Leftmost and rightmost point X coordinates found by an outermost point detecting circuit 4 are inputted to a left-right directional component selecting circuit 12, and uppermost and lowermost point Y coordinates are inputted to an upper-lower directional component selecting circuit 22. Then, the left-right end X coordinates and upper-lower end Y coordinates of a one-character area are inputted from a character area circuit 6 to the circuits 12 and 22 respectively. The circuits 12 and 22 discriminate whether each pattern component is one of constituent elements of one character or not respectively by the directions, and when a positive decision is made in both vertical and horizontal directions, a signal ''1'' is sent to the output line 300 of an AND gate 23. This signal ''1'' opens a gate 24 to transfer contour information on the pattern component from a contour tracing circuit 3 to a recognizing circuit 7. The circuit 7 performs one-character recognition.

Title: Prevention of spontaneous ignition of slack coal
Inventor: SASAKI NORIHARU
IPC: B65D90/44
Filed: 1982-08-09
Abstract: PURPOSE:To prevent spontaneous ignition of slack coal under air-borne transport from a feed tank at the bottom of a storage tank, by detecting leak of high- pressure air in the feed tank through valves and introducing an inert gas into the tank whenever the leakage exceeds a predetermined limit. CONSTITUTION:Slack coal is fed from a slack coal tank 2 via valves 4 and 4A into a feed tank 3 for temporary storage. Then valves 4 and 4A are closed and a valve 6 is opened to send slack coal 1 into a transport pipe 7 through a rotary valve 5 so that the coal may be carried by high-pressure air from a compressor 8. The flow rate of the high-pressure air leaking from the valves 4 and 4A and flowing into a storage tank 2 is detected by a flow rate detector 9. When the flow rate exceeds a predetermined limit, the slack coal 1 in the storage tank 2 can generate heat leading to spontaneous ignition and therefore a control valve 12 is opened by a control device 10 and an inert gas is sent into the storage tank 2 through an inert gas supply pipe 11 to prevent the heat generation of the slack coal 1.

Filed: 1981-09-03
Abstract: PURPOSE:To eliminate the mutual interference among mechanical filters, by cascade-connecting a false gyrator to the mechanical filter when a parallel branching connection is given among the mechanical filters. CONSTITUTION:A false gyrator IG is cascade-connected to a filter N3 of one side between input terminals, and a parallel branching connection is given between the filter N3 and a filter N4 of the other side with the input terminals used in common. The input and output impedances of the filters N3 and N4 are set RL and RS respectively; an impedance formation ratio is set 1:N; and the input impedance of a circuit in which a parallel branching connection is given between the filters N3 and N4 is set RS respectively. Therefore (n) and transmission impedance R are set at 1/(RLRS)<1/2> and at (RLRS)<1/2> respectively by the impedance matching conditions. The impedance obtained when the left side is viewed from terminals 105 and 106 is displayed as a square of the impedance RL and gyrator transmission impedance R respectively. When the RL is low, the above-mentioned impedance is proportional to the reciprocal number of the RL. Thus a sufficiently high level of impedance is obtained, and as a result, the filter has no mutual interference.
