Title: Laser beam machining apparatus and head
Inventor: AKAHA TAKASHI
IPC: B23K26/21
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To simultaneously and properly provide a laser beam and a welding arc toward a part to be welded by using one laser beam machining head without affecting the lens system. SOLUTION: The laser beam from the laser beam machining system is divided into two, with TIG head 17 being arranged between them, and gathered. The laser beam welding and the arc welding are carried out at the same time with both heads always pointing toward the same welded part, regardless of any change in the welded part and the welding position. Both the laser beam and the welding arc are simultaneously and properly supplied through one laser beam machining 13 toward the welded part without affecting the lens system so that the higher machining efficiency is attained by the improvement of other machine workabilities.

Title: Filter control circuit
Inventor: FUNAKOSHI JUNICHI
IPC: H02M1/14
Filed: 1988-10-28
Abstract: PURPOSE:To prevent a rush current when power is applied again just after release of power supply by providing a current detection element to a rush current prevention circuit of a filter. CONSTITUTION:At application of power, a contact of a rush current detection element 4 is operated to short-circuit a relay 5. When the rush current is decreased and the operating contact of the rush current detection element 4 is restored, the short-circuit of the relay 5 is released, the relay is operated by a power voltage, a low pass filter circuit comprising a choke coil 1, a fuse 7, a contact 6 and an electrolytic capacitor 2 is formed to the power supply and an overcurrent during power supply is protected by the fuse 7. At releasing of power next, the relay 5 is immediately restored to prepare for the next rush current. Thus, even if a rush current is generated through the reapplication of power just after release of the power, the filter control circuit prevents the rush current.

Title: Vehicle motion control device
Inventor: MATSUMOTO SHINJI
IPC: B62D113/00
Filed: 1992-10-13
Abstract: PURPOSE:To improve the moving performance of a vehicle at the maximum steering time of rear wheels in four-wheel steering and realize this efficiently and effectively. CONSTITUTION:The controller of a vehicle motion control device computes the target rear wheel steering angle deltar (S) of rear wheel steering angle control, and judges whether the target rear wheel steering angle value has reached the maximum steering angle deltarmax (steps 102, 103). At the time of not having reached the maximum steering angle, in the case of performing the longitudinal distribution of braking force by split point control, for instance, the target split point SP(S) is made the normal value SPo (step 105). In the case of the rear wheels being steered to the maximum steering angle, the target split point is changed over to the smaller value SPmin, for instance, from the value SPo to execute rear wheel steering angle control and braking force longitudinal distribution control (steps 104, 106). Braking force distribution to rear wheels is thereby reduced, and simultaneously the lateral force of the rear wheels is secured so as to prevent the effect of four-wheel steering from being reduced. This also serves to improve the effect of four-wheel steering control without causing the lowering of control efficiency as in lateral braking force difference control.

Title: Fuel injection valve
Inventor: KATO NOBUYUKI
IPC: F02M61/16
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of density of a central part when fuel spray is formed in a shape spreading in a conical shape by spraying with a fuel injected in a swirling state from a fuel injection valve. SOLUTION: An umbrella part 15 is arranged at the tip part of the needle 3 of a fuel injection valve having a swirl groove 14, and a slit-form notch 17 is formed in the direction of a central shaft 9. Fuel forms a swirl flow by a swirl groove 14 and by injecting the fuel through an injection nozzle 6, fuel spray is generated in a state spreading in a conical shape but the fuel spray is collided with the upper surface of the umbrellar part 15 and further widely spread. As a part of fuel spray is guided through the notch 17 to the central part of fuel spray along the direction of a central shaft 9, lowering of density of a central part is prevented from occurring. Further, when an umbrella part 15 is not arranged, the notch part 17 is formed directly in the outer peripheral part of the tip part of the needle 3. The notch 17 is not limited to a slit-form shape.

Title: Creep controller in vehicle
Inventor: NAKAWAKI YASUNORI
IPC: B60W10/18
Filed: 1991-09-26
Abstract: PURPOSE:To prevent those of driving operability, shock reduction at the time of resetting, and any hunting of start and release of control from occurring by installing a hysteresis in a threshold value as to the manipulated variable of a foot brake separately when entering into anticreep control and resetting from it. CONSTITUTION:In a system which is made so as to prevent any creep as a neutral state when a specified condition is materialized, whereas it is a forward running range, threshold value in the manipulated variable of a foot brake when entering into anticreep control is made larger than that of the manipulated variable when resetting from this time forth. In consequence, operation of garaging or the like requiring a travel of less than the creep car speed becomes very easy, and besides, after being once entered into anticreep control, braking force becomes weakened and the car can be reset in the state that the car can go forward, so that a shock is reducible. In addition, any possible hunting of starting and resetting of control on the basis of operation of the foot brake is made preventable.
