Title: Controlling device for idle rotation speed
Inventor: ATAGO TAKESHI
IPC: F02M23/04
Filed: 1979-12-14
Abstract: PURPOSE: To make not to cause A/F fluctuation in spite of idle rotation control by performing O 2  feedback control in addition to existing carburetor by-pass system.  
     CONSTITUTION: From an O 2  sensor H the signals are put out to be converted into the signals by a comparator I and proportionally integrated by an amplifier J to put out the signals. Said signals are delayed for the time t by a delay circuit K to be put out. Said delay time t is the time, wherein a period T of the control signals made by the amplifier D on the side of an engine rotation detector is counted by a counter N and said counted number is added by the correction of the engine rotation speed at the engine rotation correction circuit. In this way O 2  F/B signals is put out to O 2  F/B actuator M to be given the delay of t/T. Thereby the rotation fluctuation through ISC ΔRPM and maximum value of the A/F fluctuation ΔCO+CO 2  are not overlapped thus enabling to keep stabilized engine running.

Title: Hydraulic turbine member and its welding method
Inventor: USAMI KENICHI
IPC: C21D7/06
Filed: 1995-06-28
Abstract: PURPOSE: To prevent cold cracks of a cladding layer and to improve fatigue strength, in a hydraulic turbine member with a layer of cladding by welding, by affording a specific weld layer to a residual tensile stress of the last weld layer. CONSTITUTION: In a hydraulic turbine member with two base materials welded each other or with a cladding by welding on the surface of a base material, the weld layer is such that the surface residual stress is not more than 10kgf/ cm<2> on the surface of the last weld layer. The surface of the last cladding layer after welding is given a peening treatment at 100-600 deg.C. This peening treatment is carried out either by a cooling process after the cladding or by reheating after cooling to the room temperature. As a result, the residual stress can be reduced which is produced on the surface of the cladding member. In addition, with cold cracks prevented on the cladding layer, a fatigue strength is improved in a welding joints for members of rotary apparatus.

Title: Method for hardening titanium alloy
Inventor: OKAMOTO RYUZO
IPC: C22F1/18
Filed: 1984-08-01
Abstract: PURPOSE:To harden a Ti-Ni alloy having a specified composition up to the interior without changing the metallic color by subjecting the alloy to quench hardening. CONSTITUTION:A Ti-Ni alloy contg. 45-60atom% Ni is subjected to quench hardening by heating to 800-950 deg.C, holding for about several - several 10min and quenching such as water or oil quenching.

Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To specify a failure caused by valve element return delay of a pressure regulator by diagnosing the failure of a pressure control valve in the case the fluctuation width of pressure is detected and exceeds a prescribed value. SOLUTION: An engine fuel feed system comprises a fuel pump 1 for boosting fuel as a fuel feed system for feeding fuel to the fuel injection valve of an internal combustion engine, a fuel piping 3 for supplying high pressure fuel to each injection valve 6, a pressure sensor 2 for measuring fuel pressure in the fuel piping 3, an accumulator 5 for suppressing pressure fluctuation in the fuel piping 3, and a pressure regulating valve 4 for setting pressure in the fuel piping 3 to a prescribed value. The failure of the pressure regulating valve 4 is judged in the case where the detected fluctuation width of pressure in the fuel piping 3 exceeds a prescribed value. It is thus possible to specify a failure caused by valve element return delay of the pressure regulator from the measuring result of fuel pressure.

IPC: H02M3/335
Filed: 1981-10-14
Abstract: PURPOSE:To obtain a small-sized, reliable control circuit device by packaging all circuits on one substrate, and outputting a fault detecting signal when one of reference voltage generating circuits is faulty. CONSTITUTION:Reference voltage generating circuits 41 and 45 are provided. The output voltage of the circuit 41 is used as a reference voltage of the 1st DC input voltage applied to a terminal. Then, the power voltage to a terminal 6 is stabilized by the output voltage VREF2 of the circuit 45, and the power voltage is divided through resistances to obtain reference voltages VREF3 and VREF4 of voltage comparators 52 and 53. Those comparators 52 and 53 detect the 2nd DC input voltage being higher than the voltage VREF3 and lower than the VREF4 respectively. Even if one of the circuits 41 and 45 enters into abnormal operation, a fault detecting signal appears at the output of the comparator 52 or 53, so all circuits are packaged on the same substrate to realize size reduction and high reliability.
