摘要:
A cermet has a hard phase which contains W and nitrogen, and includes at least one selected from a carbide, nitride and carbonitride of a metal having Ti as a main component, and a binder phase having an iron group metal as a main component. A W amount contained in the whole cermet is 5 to 40% by weight, an interfacial phase including a complex carbonitride with a larger W amount than a W amount of the hard phase being present between grains of the hard phase, and when a W amount contained in the interfacial phase based on the whole metal element is represented by Wb (atomic %), and a W amount contained in the hard phase based on the whole metal element is represented by Wh (atomic %), then, an atomic ratio of Wb to Wh (Wb/Wh) is 1.7 or more. The cermet is excellent in fracture resistance and wear resistance.

A cermet has a first hard phase of a complex carbonitride solid solution, a second hard phase of WC, and a binder phase mainly comprising Co and Ni as main component(s). The first hard phase has a core/rim structure. The core is represented by (Ti1-x-yLxMoy)(C1-zNz) and the rim is represented by (Ti1-a-b-dRaMobWd)(C1-eNe), wherein L and R each represent at least one element selected from the group consisting of Zr, Hf, Nb and Ta. If a maximum thickness of the rim of the core/rim structure grains of the first hard phase is given by rmax, and a minimum thickness of the rim of the core/rim structure grains of the first hard phase is given by rmin, a number of the core/rim structure grains of the first hard phase satisfying 0.2

The invention provides a compact multistage furnace of which the installation area in a factory is decreased. A multistage furnace is configured by piling up a plurality of furnace units in the vertical direction. Each of the furnace units includes an upper heater and a lower heater layered in the vertical direction and holding a heat insulator therebetween, a support pipe disposed on one end of the upper heater and extending in the horizontal direction, a support pipe disposed on other end of the upper heater and extending in the horizontal direction, and a plurality of work support bars mounted over the support pipes. The back surface of a work supported by the work support bars is opposed to the upper heater and the front surface of the work is opposed to the lower heater of the adjacent furnace unit disposed above.
摘要:
A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements; and a parking lock mechanism having a parking lock pole preventing rotation of a parking lock gear connected to the output rotary member when a manually operated shifting device selects a parking range. One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components is selectively fixed to a stationary member through a brake. The drive control device sets a drive mode to an engine drive mode in which the brake is placed in a released state while the clutch is placed in an engaged state when a shift change is made into the parking range to achieve a parking lock with the parking lock mechanism.

One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components is selectively fixed to a stationary member through a brake. The hybrid vehicle is selectively placed in one of drive modes including a first hybrid drive mode in which the brake is placed in an engaged state while the clutch is placed in a released state, and a second hybrid drive mode in which the brake is placed in a released state while the clutch is placed in an engaged state. The drive control device comprises: an engine stop control portion configured to switch the hybrid drive mode from the second hybrid drive mode to the first hybrid drive mode, before stopping the engine according to a requirement to stop the engine in the second hybrid drive mode; a resonance restriction control portion configured to initiate positive reduction of an operating speed of the engine with an operation of the first electric motor when the operating speed of the engine has dropped below a predetermined determination value; and a torque offsetting control portion configured to control the second electric motor so as to offset a reaction force which acts on the output rotary member as a result of the positive reduction of the operating speed of the engine by the first electric motor.
