Title: Surveillance of neutron flux in nuclear reactor and apparatus for neutron measurement
Inventor: GOTO YUKINORI
IPC: G21C17/108
Filed: 1988-06-03
Abstract: PURPOSE:To intend to suppress downgrading of an extent of a thermal melting by transmitting suppression signal against output rise in case that a predetermined value, as a function of a ratio which is a ratio of the maximum neutron flux value of each local region to a signal of a core average neutron flux value, surpasses the signal of a core average neutron flux value. CONSTITUTION:The inside of a core is divided into a plurality of local regions, signals from neutron flux detectors 10a to 10d belonging to each local region are averaged by an averaging circuit 20 and neutron flux signals a of local regions are transmitted. Each neutron flux signal ai of local regions gets its maximum value MAXai determined by a maximum value detector circuit 50. Signals from the detectors 10a to 10d are averaged by an averaging circuit 30 with signals from neutron flux detectors in other local regions, and then a core average neutron flux signal b is transmitted. The maximum value MAXai and the signal b are input to a function generator 60 to generate f(MAXai/b) as a function of these ratios. A predetermined value f(MAXai/b) is compared to the signal b by a comparator 70 and when the signal b surpasses the predetermined value f(MAXai/b), a suppression signal against an output rise is transmitted.

Title: Fuel cell electrode
Inventor: TSURUMI KAZUNORI
IPC: H01M4/86
Filed: 1991-05-10
Abstract: PURPOSE:To provide a fuel cell which can suppress lowering of the output of the entire cell, which has been the disadvantage of the prior art, by joining catalytic layer with a matrix layer or the like to eliminate voids between the two layers which may occur when electrodes are constructed. CONSTITUTION:Coil-like carbon fibers are mixed into a catalytic layer containing polytetrafluoroethylene particulates and carbon catalytic particles. The flexibility of the coil-like carbon fibers added to the catalytic layer causes the flexibility of the entire catalytic layer to be improved, allowing, when the layer is joined with other matrix layers or the like to construct electrodes, the layer to be pressure welded at the interface with a slight pressure to prevent voids which are likely to occur thereat. This constitution can avoid lowering of terminal voltage arising from voids occurring at the said interface and lowering of supportability for electrodes due to reduction of voids in the matrix layer caused by the pressure welding of the catalytic layer and the matrix layer with a strong pressure which is done to minimize the said voids.

Title: Electrode structure for ultra thin plate piezoelectric resonator
Inventor: MORITA TAKAO
IPC: H03H9/13
Filed: 1990-05-25
Abstract: PURPOSE:To avoid disadvantage caused due to increase in a parallel capacitance of a resonator by forming a conductor film being an opposite electrode to a position other than a region corresponding to a lead pattern on an opposite face of a vibration part. CONSTITUTION:A part 16 corresponding to a region of a vibration part 3 of an electrode lead 7 prolonged from an opposite electrode 6 is eliminated from a full face electrode 5 added to a recessed part 2 of an ultra thin piezoelectric block 1. This is because the said vibration part 3 is very thin and a capacitor with a large capacitance is formed when a conductor film exists on the front and rear side of the said vibration part. In contrast with the above fact, an annular surrounding part 4 is thick and even if a conductor film exists on the front and rear face of the part 4, so much capacitance is not caused and no detrimental effect is given on the capacitance ratio of the resonator.

Title: Dc recovery circuit
Inventor: SAKAGUCHI YASUNORI
IPC: H04N5/18
Filed: 1988-06-01
Abstract: PURPOSE:To prevent the production of sag even when a load is driven directly by providing a buffer amplifier between the input and output and applying DC recovery so that a pedestal potential at the output is equal to a reference potential. CONSTITUTION:The electric charge quantity in a coupling capacitor 80 is controlled by using a clamp pulse so that the pedestal potential at an input terminal 30 is equal to a reference voltage source potential. Then an NPN transistor(TR) 8 plays a role of a buffer receiving a potential at the input terminal 30 at a high input impedance, giving a potential to a base of a NPN TR 2 with a low impedance and outputting an input signal to the output terminal 40. Thus, a current driving the load connecting to the output terminal 40 is supplied from a power terminal 60 or supplied from a current source 9. Thus, the electric charge of the coupling capacitor 80 is not discharged by the load and no sag caused in a period of 1H.

Title: Apparatus for controlling ignition timing of internal- combustion engine
Inventor: OOMORI YOSHIAKI
IPC: F02P5/15
Filed: 1983-07-25
Abstract: PURPOSE:To reduce the deviation of ignition timing, by changing automatically, according to whether an engine is in high speed rotation range or in low rotation range, the time that is used as a reference on which the calculation of the timing of the operation of an igniter is based. CONSTITUTION:A rotational angle sensor 1 is composed of a rotor 2 on a crank shaft or in a distributor and a sensor of a photoelectric type, magnetic transducing type, etc. that comprises pickups A, B opposed to one projection P on the circumference of the rotor 2. As the rotor 2 rotates, the sensor 1 detects the time when it is positioned opposite to the pickups A, B every time when the projection P turns 180 deg., and the sensor 1 generates reference positional signals respectively. Based upon the signals, if the rotational frequency is in the high rotational range, the signal generated earlier than the other is used, and if the rotational frequency is in the low rotational range, the signal generated more later than the other is used as a reference signal. Thus, even in the low speed rotation range where fluctuation of rotation is high, the ignition timing is deviated hardly.

Title: Thin-film cold cathode and its manufacture
Inventor: IKEDA JUNJI
IPC: H01J9/02
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To manufacture an insulator for element separation high in insulation withstand voltage without impairing the characteristics of an intrinsic semiconductor in the process of manufacture. SOLUTION: In this thin-film cold cathode, when a voltage is placed between a thin-film electrode 4 and a back electrode 5 so as to positively polarize the thin-film electrode 4, electrons in a conduction band of an n-type Si- semiconductor substrate 1 are injected into a conduction band of an intrinsic semiconductor 3. Because the intrinsic semiconductor 3 is highly resistive, a voltage drop is produced in the intrinsic semiconductor 3 to set up a strong electric field. The electrons injected from the n-type Si-semiconductor substrate 1 are accelerated by the strong electric field, and thus electrons having energy exceeding the work function of the thin-film electrode 4 are emitted into a vacuum.  In manufacturing this thin-film cold cathode, the formation of a field oxide film 2 acting as an insulator for element separation is performed prior to that of the intrinsic semiconductor 3, and therefore the intrinsic semiconductor 3 can be prevented from being damaged while the insulator for element separation is formed.
