Title: Diagnostic device for crank angle sensor
Inventor: SEKINE MANABU
IPC: F02D45/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To perform diagnosis by only a signal output of a crank angle sensor serving as a diagnostic object. SOLUTION: A pulse signal from a crank angle sensor is input, and a period TREF thereof is measured (S1). This pulse signal period TREF is converted into an engine speed Ne, and processed to be averaged, and an average rotational speed Nem is calculated (S2, S3). From a table with an engine speed as a lattice, a diagnosing data (ideal period) TREFO corresponding to the average rotational speed Nem is retrieved (S4). A difference ΔT between the actual pulse signal period TREF and the diagnosing data TREFO is calculated (S5), and compared with a threshold value SL (S7). When the difference ΔT exceeds the threshold value SL, NG is diagnosed (S9). In the case of diagnosing OK (S8), by learning based on the actual pulse signal period TREF, the diagnosing data TREFO is updated (S10).

Title: Fixing unit
Inventor: KOBORI MASAAKI
IPC: G03G15/20
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent such a state that the detection part of a sensor detecting the temperature of a heating roller cannot abut on the heating roller or it breaks from occurring because it is bent outside in the radial direction of the heating roller by arranging a supporting member abutting on the detection part on an opposite surface side to the slidable contact surface of the detection part with the heating roller. SOLUTION: A projection part 65 is formed in a fixing unit 60. This means, the projection part 65 being the supporting member of the detection part 64a is made to project to the upper surface of a protection cover 69. Besides, the projection part 65 is formed in a rib state. Then, the detection part 64a is supported by making the projection part 65 abut on the opposite side surface to the slidable contact surface of the detection part 64a with the heating roller 61. Thus, even when the force of a reverse direction to a press-contact direction with the roller 61 is imposed on the detection part 64a in the case that a paper jammed because it is wound round the roller 61 is drawn out, such a state that the detection part 64a cannot abut on the roller 61 or it breaks is prevented from occurring because it is bent outside in the radial direction of the roller 61.

Title: I/o bus
Inventor: SEKI YUKIHIRO
IPC: G06F13/36
Filed: 1995-05-10
Abstract: PURPOSE: To provide the bus topology constitution system which doesn't degrade the processor performance by providing an I/O bus bridge circuit between a first I/O bus and a second I/O bus to adopt a bus topology constitution like a loop. CONSTITUTION: An I/O-I/O bridge 6 connecting first and second I/O busses 5A and 5B is inserted between these busses to constitute a topology like a loop. Then, it is unnecessary to pass a processor bus 3 at the time of access between first and second, I/O busses 5A and 5B. Thus, the access performance between I/O busses 5 is improved in the system of plural I/O busses 5 of the parallel topology where distances to a processor 1 and a main memory 2 are equal. Since the band width of the processor bus 3 is not used for the transfer where it is unnecessary to pass the processor bus 3, the performance of instruction fetch operation or the like between the processor 1 and the main memory 2 is not degraded.

Title: Radar signal processor
Inventor: ASANO FUKUYOSHI
IPC: G01S13/87
Filed: 1991-05-16
Abstract: PURPOSE:To always monitor the azimuth direction of a transmission beam by processing the azimuth angle monitoring processing of a transmission beam in an azimuth discrimination circuit using a microcomputer after SR data and SSR data are composed. CONSTITUTION:Data from an SR/SSR composition circuit are input 5 into an azimuth angle discrimination circuit 4. When the discrimination in which the input data is the target data of SR/SSR composition is performed, the target is discriminated on whether it is in the neighborhood of the azimuth center of a beam. If the distance azimuth /SIGMA is smaller than K1 (a parameter for prescribing the range which is regarded as an azimuth center), it is discriminated as the data in the neighborhood of the azimuth center of the beam. Next, the azimuthes of the SR data and the SSR data are extracted therefrom to store 7 them as a pair thereof. If the stored data number is K2 (variable parameter) or more, the difference of each average value of the SR and the SSR data azimuthes is found. If the difference is less than K3 (a variable parameter indicating the error allowable range of the azimuth angle of a transmission beam), the discrimination in which the azimuth angle of the transmission beam is normal is performed.

Filed: 1982-06-29
Abstract: PURPOSE:To perform regular and proper ignition timing control constantly in a system in which a fundamental ignition timing is corrected in response to the output from the knocking sensor by a method wherein the ignition timing correction toward spark delay is set to a higher value when the knocking is sensed at the cylinder with low sensitivity of knocking condition. CONSTITUTION:An igniter 4 for multi-cylinder type internal-combustion engine is controlled such that uniform ignition timing control is performed for a plurality of cylinders with the ignition timing instruction signal which is provided by correcting the fundamental ignition timing calculated by the outputs from an air flow meter 24 and a rotary angle sensor 52 in a digital control circuit 56 in response to the condition whether the knocking occurs or not. In this case, when the knocking is sensed at the cylinder with low sensitivity of knocking, e.g. the sixth cylinder of six-cylinder type internal combustion engine in said control circuit 56, the ignition timing correction value toward spark delay is controlled to show a higher value. In ths way, the excessive spark delay or excessive spark advance is eliminated to improve the output of the engine as well as the fuel consumption.

IPC: G21C3/60
Filed: 1987-05-11
Abstract: PURPOSE:To enhance bleedability and to prolong the period of operation cycles by decreasing the amt. of the additive metals to be added to metallic fuel while preventing generation of an eutectic phenomenon. CONSTITUTION:The content of the additive metals such as zirconium, molybdenum and titanium to be added to the metallic fuel 12 consisting of metallic uranium, uranium-plutonium alloy, etc., is so specified that the content of the zirconium is decreased to 10% in the half part on a coolant outlet side and to 5% in the half part on the coolant inlet side. The content distribution may be the reversal stepped or curved shape. Since the content of the additive metals can be thereby made lower than the fuel assembly having the content of the additive metals uniform over the entire part, the density of fissionable atoms can be increased and the bleedability is improved; in addition, the period of the operation cycles is prolonged. The content is made lower on the coolant inlet side than on the coolant outlet side where the temp. distribution of fuel clad pipes is high and, therefore, the generation of the eutectic phenomenon is prevented as well.
