Title: Mos image sensor signal processing circuit
Inventor: SHIDA FUMIO
IPC: H04N5/361
Filed: 1988-05-16
Abstract: PURPOSE:To obtain current voltage conversion with high accuracy without being affected by a DC offset voltage of an amplifier by fixing an output potential when no output signal current in one picture element period exists to a prescribed potential at a constant period. CONSTITUTION:A DC recovery signal is generated for a period when no output signal current exists in one picture element period, that is, for a period of a flat portion of a signal waveform when no transfer clock noise 402 and to signal component 401 exist. That is, the signal potential during the period is fixed to the potential of a reference voltage output terminal 307 to apply DC recovery for each picture element period. Because of DC recovery, a DC offset voltage before the DC recovery device 104 does not entirely give effect on the integration device 105. Naturally, the DC drift depending on the temperature of the circuit voltage converter 102 and the voltage amplifier 103 is not affected. Moreover, since the DC recovery period is short, the occurrence of defective DC recovery such as sag caused by the DC recovery is reduced.

Title: Coated optical fiber
Inventor: HONGO HITOYASU
IPC: G02B6/44
Filed: 1995-04-21
Abstract: PURPOSE: To facilitate the removal of coatings and to make it possible to easily produce simultaneously coated optical fibers or single coated optical fiber of various diameters by removing the coating layer of the outermost layer to expose the coating layer which is heretofore an inner layer, thereby constituting the fresh outermost layer. CONSTITUTION: The coated optical fiber has plural pieces of the coating layers 1 to 4 which are composed of a UV curing resin and are designed to the prescribed diameter. The coating layer of the outermost layer, for example, the coating layer 4, is removed to expose the coating layer 3 which is heretofore the inner layer, by which the outermost layer is freshly formed. The easy arraying of plural pieces of the coated fibers at a prescribed pitch is made possible and the easy production of the simultaneously coated fibers is made possible. Designing the coated fibers in such a manner that the set value of the outside diameter of the coatings to be removed and peeled is approximately plural times 0.25±0.01mm is preferable for the purpose of connection.  Further, the curing shrinkage rate of the coatings of the outer layers which is smaller than that of the inner layers is preferable in terms of removing and peeling the outer layers in the case of subsequent working.

Title: Detection for fault recovery
Inventor: UCHIYAMA TOSHIHIKO
IPC: H04B10/275
Filed: 1987-05-18
Abstract: PURPOSE:To prevent an uncertain part of an transmission line from being fetched into the network by providing a function adding its own station address and sending to both direction of the pre-stage and the next-stage when a transmitter disconnected from the network receives a fault recovery supervising signal, to each transmission station. CONSTITUTION:A terminal station in the turn back state calculates number of bypassed stages between its own inter-network terminal stations, and stations at the outside of the network (relay stations) or other inter-network terminal station from an address in a fault recovery supervising signal received from the outside of the network and a transmission station connection order table stored in advance and when above mentioned number exceeds the maximum allowable bypass stage number stored in advance, since it is possible to cause instability in the transmission line, it is regarded as the fault recovery and the ring network is not constituted again. Thus, unstable network constitution is surely prevented.

Title: Signal transmission method by current transformer
Inventor: HAYAMIZU KAZUO
IPC: H04L25/49
Filed: 1980-08-28
Abstract: PURPOSE:To form a dead time of signal easily and surely at the secondary side of a current transformer, by providing a power supply and switching circuit to flow rectangular pulse currents being opposite with each other, and a switch circuit, and establishing tri-state of positive, negative and zero, at the secondary side with switch operation. CONSTITUTION:A primary conductor P1 of a current transformer CT is connected to a DC power supply E1 via a switch S1 and other primary conductor P2 is connected to a DC power supply E2 via a switch S2 respectively, and the polarity is selected so that opposing current flows to the conductors P1 and P2. When the switch S1 is closed, a current I1 flows to the conductor P1 and when the switch S2 is closed, a rectangular pulse current I2 opposite to the current I1 and equal in the amplitude flows to the conductor P2. When the switches S1, S2 are closed so that the currents I1, I2 flow at the same time, the magnetic flux by both the currents is canceled into zero, and the secondary output of the current transformer goes to zero. When the switches are actuated so that a part of the currents I1, I2 is overlapped at the front and rear edge of the pulse, the secondary output of the current transformer shows positive and negative polarities having a dead time.

Title: Pulse counting circuit
Inventor: TOBE TERUO
IPC: H03K23/66
Filed: 1980-08-29
Abstract: PURPOSE:To eliminate the need for a buffer memory while eliminating an error in count values by supplying pulses from an oscillator to the 2nd and 3rd counters until the count value of the 1st counter counting input pulses coincides with that of the 2nd counter. CONSTITUTION:A pulse (a), when inputted, is counted by a counter COT1, whose count value (b) is compared with the count value (c) of a counter COT2 by a comparator CON, which when the both do not coincide mutually, drives an oscillator OSC to make the counters COT2 and COT3 count pulses (e) until the counters COT1 and COT2 have the same count value. As an output request signal (f) goes up to a high level, the pulse (e) is ceased and in this state, the count value (g) of the counter COT3 is outputted. During this period, the input pulses (a) are counted by the counter COT1 and if the output request signal (f) goes down to a low level, the oscillator OSC outputs pulses (e) until the counters COT1 and COT2 have the same count value, thereby correcting the count values.
