Title: Community antenna device
Inventor: UIREMU FUREDERITSUKU MARII FUR
IPC: H04N7/10
Filed: 1982-12-14
Abstract: Community antenna arrangement I-III for a frequency-division multiplex transmission of at least four television signals, comprising a frequency-conversion arrangement (C1-Cj, I1-Ik) connected to a distribution network (II, III) for converting the channel frequency distribution of the television signals from an input channel pattern to an output channel pattern in which output channel pattern the picture carriers of the television signals succeed each other with frequency spacings of which not more than two consecutive frequency spacings are mutually equal. By choosing the picture carrier distances in the second output channel pattern to be equal to an integer of a certain frequency interval, the higher order intermodulation products appear at frequencies which are mutually spaced over fixed distances of the order of this frequency interval which distances equalize an integer of said frequency interval relative to the picture carriers. According to the invention, this frequency interval must be chosen so that the intermodulation products predominantly occur in interference-insensitive positions in the TV-signals spectrum, as a result of which the effect of interferences due to intermodulation is significantly reduced.

Title: Light position detecting element
Inventor: ASANO AKIHIKO
IPC: H01L31/16
Filed: 1987-09-02
Abstract: PURPOSE:To enable the detection of a light incident position with high precision even in the vicinity of surface electrodes, by providing both surfaces with photoelectromotive force layers which are low-resistance surface layers and made of semiconductors, and by mounting a common electrode on one surface layer and dividing the other surface layer into a plurality of parallel band-shaped parts and next mounting respective surface electrodes on both ends of each band-shaped part. CONSTITUTION:P type surface layers 14-16 are formed on a surface side of a single-crystalline silicon plate 1, and an n-type rear common electrode 13 is formed on its rear side, and an intermediate layer is formed as an (i) quality photoelectromotive force layer 12 between them. The surface layers 14-16 are composed in so a way that three of the layers of (a) in width are juxtaposed with a distance (b) in between. Surface electrodes 41-43 and 51-53 are formed on both respective ends of the surface layers, and they are divided into groups and connected to each other by the use of connection lines 61, 62. Since the surface layers are divided into N parts and limited in their widths to be bandshaped, expansion of photocurrents can be suppressed to be equal to or smaller than the widths of the respective divided surface layers when the photocurrents are made to flow from the light incident position to the respective surface electrodes. Therefore a detection error of the light incident position becomes 1/N, so that a light position detecting element with high precision can be manufactured.

Title: Medium feeder
Inventor: YOKOYAMA KAZUO
IPC: B41J15/04
Filed: 1986-09-18
Abstract: PURPOSE:To enable elimination of a necessity to adjust a positional shift by LF when the title device is set OFF anew prior to use through a 'set ON' operation by selecting a transport of continuous media upon a command signal from an external device after they are transported to a reverse direction and restored to an original position by control of a reverse feed control means. CONSTITUTION:If a LF button 4a is operated for movement of the position of paper 1a, a pulse signal a is transmitted to a counter 5a and a motor drive control 7a from a main control 6a, and drives an LF motor M. At the same time, a feed value is counted by the counter 5a. If an ON/OFF selector button 3 is set ON, an ON selection signal b is transmitted to the counter 5a by the main control 6a. The counter 5a transmits a pulse signal c which is equivalent to a counted feed value sequentially to the main control 6a and motor drive control 7a. The main control 6a receives the pulse signal c as an ON feed stop signal to set an interface circuit to 'shut-off' state. The motor drive control 7a reverses the LF motor M upon the pulse signal c, and consequently a paper feed mechanism 11 is driven to return the paper 1a to an original position.

Title: Flocculating state monitoring apparatus
Inventor: MIYAMOTO KENJI
IPC: B01D21/30
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To easily monitor the flocculating state of a liquid to be treated by installing an inspection container having an aperture part in a flocculating tank containing the liquid to be treated which is mixed with a flocculating agent, changing the liquid to be treated through the aperture part, measuring the turbidity of the liquid to be treated, and informing the abnormality if necessary. SOLUTION: An inspection container 31 is installed in a flocculating tank 12 and the supernatant liquid in an upper part of the liquid to be treated in the inspection container 31 is transported to a turbidity meter 51 by a pump 35 through a transportation pipe 33. The turbidity is inspected by the turbidity meter 51 and after that the liquid to be treated is changed by a changing apparatus 41 and this process is repeated. If abnormality is found in the turbidity inspection, an alarm is given by an alarm 62. Control is carried out by a controlling apparatus 61. Since both inorganic and polymer flocculants are added to the flocculating tank 12, the flocculating state can be more precisely observed. As another proposal, there is suggested a method in which a turbidity meter is installed in the inspection container 31 and the turbidity of the liquid to be treated is measured.  By these methods, the flocculating state of the liquid to be treated is monitored in a manless manner and flocculating treatment control can be automatically carried out. Further, the state of flocs can be easily known by a turbidity sensor.

IPC: H02P25/098
Filed: 1993-08-12
Abstract: PURPOSE:To give a system damping with a differential feedback system and prevent or suppress torsional oscillation by feeding back the complete differential value of output torque in place of the approximate differential feedback of output torque. CONSTITUTION:A complete differential block 3 estimates an output torque complete differential value. If a torque controller 4 constituted of a proportional integrator computes the transfer function from torque command T* to output torque Ts, it becomes the following formula. Ts(s)/T*(s)=p.omegaO<2>.(Kp.s+ Ki)/(S<2>+Kd.rhoomegaO<2>.S<2>+Kp.rho.omegaO<2>.S+Ki.rho.omegaO<2>. And differential gain Kp gets in S<2> term, and fulfills the effect of oscillation control. Hereby, a highly reliable output torque controller for a motor drive system, which has completely removed torsional oscillation, can be materialized.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for laser which is relatively expensive and is accurately adjusted and its support circuit at each addition/leading-in node by the use of a part of light from an input optical signal and sending an output optical signal. SOLUTION: A central office CO 184 offers an optical signal, which reaches an addition/leading-in node 188 along an optical fiber path 186 and has plural wavelengths. The node 188 represents one of many nodes which constitute a ring 180. An optical addition/leading-in multiplexer 194 uses a wavelength selecting device such as a wavelength diffraction grating router WGR 196 and divides the optical signal into paths 200a to 200n. An optical transmitter-receiver 208 outputs a output optical signal of specific wavelength from a part of a received optical signal to a path 212 to a WGR 202. The node enables a ring architecture which has continuous or non-completed optical paths of specific wavelength.
