Patent JP-H02311134-A (JP)
Title: Fuel-cell generating set
Inventor: MOGI HIROSHI
IPC: H02J9/06
Filed: 1989-05-26
Abstract: PURPOSE:To shorten the time up to the return of the output voltage of an inverter from the restart of the inverter by stopping only the inverter when the abnormality of a system is generated and supplying an auxiliary equipment, a system controller (SC) and a programmable controller (PC) with power by a capacitor for backup. CONSTITUTION:When any abnormality is generated in a system power supply 14, a switch SW1 is turned OFF, and the system power supply 14 and a system are detached. Since a power supply source to an auxiliary equipment 5, a system controller(SC) 7 and a programmable controller(PC) 9 is lost by the detaching, feed from a capacitor 16 for backup is started. When discharge from the capacitor 16 is completed, the system is stopped, thus requiring the restart of an inverter 3. When the system power supply 14 is abnormal, only the inverter 3 is stopped, and a chopper 2 continues to be operated, thus returning the operation of the inverter 3 only for the rise time of the inverter 3. Accordingly, when the system is returned, the time required for restarting the inverter can be shortened.

Inventor: UEKI YOUICHI
IPC: H02M3/10
Filed: 1978-10-26
Abstract: PURPOSE: To simplify a circuit and reduce its cost, by using a general-purpose arithmetic amplifier and integrating an oscillator with a pulse width control circuit.  
     CONSTITUTION: A general-purpose operational amplifier OPA is provided and an oscillator is integrated with a pulse width control circuit so that a switch control section SWC is formed. In the switch control section, a capacitor C 2  is charged through a diode D 3  and discharged through another diode D 4 . The output signal of the switch control section SWC is repeatedly raised and lowered to turn the switch SW on and off. When the output signal is low, the time of closing of the switch SW is equal to the time constant of the capacitor C 2 , the diode D 4  and a resistor r 4  and fixed. When the output signal is high, the time of opening of the switch SW depends on the time constant of a parallel circuit comprising the capacitor C 2 , the diode D 3 , a resistor r 3  and a transistor Tr. The current of the transistor is controlled to regulate the time of opening of the switch SW. A cheap device of a simple circuit is thus obtained.

Title: Nitriding steel
Inventor: LEPPAENEN RAINER R
IPC: C22C38/22
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To improve a nitriding depth, workability and a production property by containing C, Si, Mn, Cr, Mo, Al, Fe in the nitriding steel by a specified quantity. SOLUTION: The nitriding steel contains, by weight, 0.1-0.18% C, 0.2-0.4% Si, 0.75-1% Mn, 2.5-4% Cr, 0.5-0.65% Mo, 0.1-0.35 Al and the balance essentially Fe. Repeatability of a steel property is improved as a width of a Mo content is narrower, as an Al content increase, a hardness is increased but a cutting property is deteriorated. As comparing to a conventional nitriding steel, after subjecting to plasma nitriding at 530 deg.C for 24 hr. the neighborhood of a surface is significantly hardened and a nitriding depth is increased. As comparing the tool life to a carbide turning cutting of ISO3685, the tool life is three times, at a cutting speed of 200 m/sec, that of a 41 CrAlMo 7 steel. It is produced by a conventional method, a worker skilled for nitriding can easily change a property of the nitriding steel by changing a concentration of an alloy content.
