Title: Fault information transmission system and method for optical transmitter having ring network
Inventor: SATO KENJI
IPC: H04B10/032
Filed: 1992-04-15
Abstract: PURPOSE:To improve the reliability and the convenience of use by giving a command of inclusion of fault information to a path layer in which no error is detected as a new path layer and of transmission of the result to an opposite station through an optical transmission line when the error is detected from a path layer of only one system. CONSTITUTION:Pass layer terminators 200w, 200e apply photoelectric conversion to respectively received transmission data. Line layer terminators 100w, 100e respectively fetch data of a line layer, apply a prescribed processing and include data of a new line layer to the transmission data. The terminators 200w, 200e fetch data of a pass layer of the received transmission data and apply multiplexing or the like to the data. Error detection sections 300w, 300e detect an error in the data of the path layer. A path layer selection section 400 selects an optical transmission line in which no error is detected and connects the selected transmission line to a subscriber system equipment group. An error monitor section 600 monitors whether or not the error is detected by only one path layer of the transmission data, and in this case, a fault information transmission command section 700 gives a command of including a new path layer having fault information representing the detection of an error even in the selected path layer with no error detected therefrom into the transmission data and of sending the result to an opposite station through the optical transmission line.

Title: Rotation timing detector for rolling mechanism
Inventor: TAKEMOTO HIDETSUGU
IPC: F02D41/40
Filed: 1987-04-17
Abstract: PURPOSE:To accurately detect a desired timing by calculating the time elapsed from the last pulse using data on the time interval between the same position pulse of the preceding rotation cycle and the next pulse. CONSTITUTION:An electronic control circuit 26 obtains a spill command angle from ROM 26b according to a signal of an accelerator opening sensor 41. Secondly, the spill command angle is separated into an integer quatient (n) obtained by pulse output angle interval and a remainder angle QR. In case of n=5, for example, the remainder angle QR is converted to rotation time TSPON by the time interval between a pulse signal xsi5 and a pulse signal xsi6 of the preceding cycle. Though normally (n) is 3, the width may be made larger. Subsequently, a value of (n) is set on an angle counter of RAM 26c, and TSPON is similarly set on a time counter thereof. Pulse signals are counted starting from a reference pulse signal xsi0, and when it amounts to xsin, the time counter starts counting time. After the lapse of rotation time TSPON, a spill solenoid valve 20 is opened. Accordingly, a desired rotation timing can be obtained.

Title: Ac current detecting circuit
Inventor: TAKADA KENZOU
IPC: H04M3/06
Filed: 1983-05-31
Abstract: PURPOSE:To detect a current value without distortion even for a capacitive or inductive current by inputting a voltage across both terminals of a resistor connected in series to an AC source to four current mirrors, rectifying each output and adding the outputs. CONSTITUTION:When an AC voltage is fed to a terminal VR and a capacitive load is connected to a subscriber terminal device, a current i0 shown in a solid line at a positive half cycle of a current IR and a current i0 shown in a broken line when the IR is at a negative half cycle flow respectively. Then the output of the current mirror P1 flows to a resistor R102 via a diode D1 as a current i1 while the terminal VR is positive with the current i0 at a positive half cycle, an output of the current mirror N2 flows to a P3 via a diode D2 while the terminal VR is negative and the same amount of current flows to the resistor R102 as an output of the current mirror P3. Currents i3, i4 flow similarly when the terminal VR is negative with the current i0 at the negative half cycle. Thus a current value without distortion is obtained by adding the currents i0-i4 after rectification at an output terminal side of the resistor R102.

Title: Fuel increase controller of internal combustion engine
Inventor: NAKAI MASAYOSHI
IPC: F02P5/15
Filed: 1987-04-20
Abstract: PURPOSE:To obtain a fuel increase controller which can execute both the fuel increase, that is, the increase in quantity of injection fuel, for ignition delay and the fuel increase for overheat prevention simultaneously without occurrence of a misfire by mounting a limiting means which limits the total fuel quantity of both the ignition-delaying fuel increase and the overheat- preventing fuel increase to the specified value. CONSTITUTION:A control circuit 45 first counts the reference fuel injection time on the bases of various detected signals of a knocking sensor 36 and so on. Said circuit 45 calculates the delay fuel increase coefficient based on both the compensated delay angle relating to a knocking and the compensated delay angle for an overheat and searches from a map to determine the overheat preventing fuel increase coefficient corresponding to the current engine load. Next, when said overheat preventing fuel increase coefficient is over the specified value, said circuit 45 sets the fuel increase coefficient for the delay ignition to zero because of no possibility of a misfire. And since when said overheat preventing fuel increase coefficient is below the specified value, there is enough possibility of the misfire, said circuit 45 may set the total fuel increase coefficient of the delay fuel increase coefficient plus the overheat preventing fuel increase coefficient. Thereafter using said coefficient and the compensating coefficients of intake temperature, cooling water temperature and so on, said reference fuel injection time is compensated so that the final fuel injection quantity is determined.
