CONSTITUTION:An intake air filling amount is calculated by an intake air filling amount calculating means (B) on the basis of the intake air amount and the rotational speed of an engine (A). High load condition of the engine (A) is judged by a high load judging means (C) on the basis of the output of the intake air filling amount calculating means (B). In such constitution, operation of external engine accessories (D) acting as the load of the engine (A) is detected by an external engine accessories operation detecting means (E). During a period from operation start of the external engine accessories (D), the high load judgement is inhibited by a judgement inhibiting means (F). When the high load is judged, a fuel supply amount to the engine (A) is increased in correction by a high load time fuel increasing means (G). When the engine (A) is in non-idling condition, inhibition by high load judgement is released by an inhibition releasing means (H).

Title: Base plate for concrete slab having deformed steel material as truss bar
Inventor: NAGAI TERUMARO
IPC: E04B5/38
Filed: 1995-06-09
Abstract: PURPOSE: To improve the strength by a method wherein when embedded materials comprising synthetic resin expanded items are arranged at predetermined intervals and a lower chord of truss bar is embedded in concrete, at least a top chord and lower chord of a truss bar is formed from a deformed steel bar. CONSTITUTION: Since a lower chord 22a of a truss bar 20 is formed from a deformed bar steel, the adhesion of the surface of the chord 22a to the concrete of a concrete base board 3 is improved. Therefore, when a hook is hung on a top chord 21a to remove the concrete and transport it, even if concentrated load is exerted on the lower chord 22a, separation can be avoided. In the case that stab upper end bars are mounted using the chord 21a as a spacer and concrete is placed at a site, the chord 21a is a deformed steel bar, and hence adhesion thereof to the concrete is improved. And when a shearing force exceeding a design value acts due to an earthquake or the like, the surface of the truss bar 20 is prevented from being separated from the placed concrete. As a result, separation of truss bar and occurrence of cracks can be avoided.

Title: Ion carburizing furnace and carrying jig
Inventor: KATO TAKEO
IPC: C23C8/36
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an ion carburizing furnace which can maintain stable glow discharge. SOLUTION: At the time of carrying a carrying object 6 constituted with a work 4 and a carrying jig 5 laying the work 4 into an ion carburizing treated chamber 2 while travelling on rollers 11, this object is held up with plural columns 10 and negative voltage is impressed through the columns 10 while heating with a resistant heating heater 8. At this time, the resistant heating heater 8 is used to an anode and the glow discharge is generated to execute the ion carburization. Since a heat insulating plate 14 is not used as the anode, abnormal discharge is not generated between the columns 10 and the heat insulating plate 14. In the case of selecting arbitrary three pieces in plural columns 10 holding up the carrying object 6, the contacting part between the columns 10 and the carrying object 6 is made so as to be <=1.0A/cm<2> current density.  Even in the case of developing the warp and the strain in the carrying jig 5, contact resistance is small and the large current can be flowed while maintaining the stable glow discharge.

Title: Insulated gate type field effect transistor
Inventor: KAN MINKIYUU
IPC: H01L21/28
Filed: 1994-06-24
Abstract: PURPOSE: To provide an insulated gate field effect transistor in which leak current is reduced at the time of turn off and sufficient gate drive capacity is obtained at the time of turn on. CONSTITUTION: A pn junction is formed by a first conductivity type layer 26a and second conductivity type layers 26b, 26c in a gate electrode 26 which is further provided with voltage supply layers 26d, 26e through pn junction with the second conductivity type layers 26b, 26c. The first conductivity type layer 26a is applied with a gate control voltage and the voltage supply layers 26d, 26e are applied with an intermediate voltage between the ON and OFF gate control voltages. Since the transistor is biased forward when an ON voltage is applied, the ON voltage is also applied to the second conductivity type layers 26b, 26c and the gate electrode 26 has an effective length L1. When an OFF voltage is applied, the transistor is biased reversely and the OFF voltage is applied only to the first conductivity type layer 26a and thereby the gate electrode 26 has an effective length L2.  Consequently, sufficient gate drive capacity is ensured at the time of turn on and leak current is reduced at the time of turn off through an offset resistance structure.
