Title: Upright mos electric field effect transistor
Inventor: KITAMURA KAZUYOSHI
IPC: H01L29/73
Filed: 1988-05-02
Abstract: PURPOSE:To decrease a drain region in resistance so as to enable an ON- resistance to decrease by a method wherein a conductivity modulation is made to occur inside a high resistive drain region. CONSTITUTION:An n-type emitter region 14 isolated from a source region 13 is made to be of a zero potential, and when a positive voltage is applied on an n-type drain region 11 and a gate oxide film 15, a channel is formed on the surface of a p-type channel forming impurity region 12 and a vertical MOSFET is made electrically conductive. A current is made to flow into the n-type source region 13 from the drain region through the channel and furthermore flow into the channel forming impurity region 12 electrically short-circuited to the source region and the emitter region 14. In this process, a p-n diode composed of the channel forming impurity region 12 and the emitter region 14 is forward biased and an npn bipolar transistor consisting of the drain region 11, the channel forming impurity region 12, and the emitter region 14 starts to operate. By these processes, a conductivity modulation is made to occur inside a low concentrated drain region of high resistance and the drain region is made to decrease remarkably in resistance, consequenly an ON-resistance decreases.

Title: Multifrequency reflector antenna
Inventor: MOSUTAFUA SEIDO AFUIFUI
IPC: H01Q21/30
Filed: 1981-07-15
Abstract: A multifrequency antenna includes a main reflector for signals in a low frequency band. One or more portions of the main reflector are deformed to provide one or more auxiliary reflectors for signals in one or more higher frequency bands. The feed for the low frequency band is located axially of the main reflector, while the feeds for the higher frequency bands are offset to the side of the low frequency feed. The lateral and axial offsets of the vertex of an auxiliary high frequency reflector from the vertex of the main low frequency reflector and the focal length of the auxiliary high frequency reflector are selected to minimize the degradation of the performance in the low frequency band.

Title: Fuel cell characteristic diagnostic method and fuel cell operating method
Inventor: HORIUCHI HIROSHI
IPC: H01M8/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a characteristic diagnostic method of a fuel cell capable of easily avoiding damage of the fuel cell caused by disturbance in a field plant. SOLUTION: An air flow rate supplying to an air electrode is changed in plural levels of air flow rate containing the rated air flow rate, cell voltage and DC current in each level are measured. Each mean oxygen concentration is found from each oxygen concentration in the inlet and outlet of the air electrode obtained from each air flow rate and each DC current. An extrapolated value of the cell voltage in pure oxygen concentration is found by the primary regression of the mean oxygen concentration in each measured point and the cell voltage, and oxygen gain is found from the difference between the cell voltage and the rated cell voltage corresponding to the rated air flow rate. The gas diffusion performance of the air electrode is diagnosed from the oxygen gain.

IPC: H04J3/14
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an error addition circuit with a simple circuit configuration in which an error is added accurately according to an object error rate. SOLUTION: An SDH frame including digital information to be sent and a B2 byte is sequentially fed to an EOR gate 4. An interrupt signal generating circuit 1 receiving an error addition timing control signal synchronously with the arrival of the B2 byte generates an interrupt signal. Every time the interrupt signal generated from the circuit 1 is received, a CPU control circuit 2 calculates an error addition bit number corresponding to an error rate of the SDH frame. The error addition bit number is given to the EOR gate 4 via an AND gate 3 by the error addition timing control signal and the error corresponding to the error addition bit number is added to the B2 byte of the SDH frame.
