  • Publication number: 20020047305
    Abstract: In a vehicle brake apparatus for executing ABS control to prevent a wheel from locking in such a manner that braking force is controlled so as to keep a slip ratio of a wheel at a target slip ratio so that an excessive drop of a wheel speed from a vehicle body speed is adjusted, an output current for driving a braking actuator is set to a current on which oscillating waves are superimposed during ABS control so that the wheel speed changes to show oscillating waves. Even if the wheel speed once drops to an extent that the slip ratio exceeds the target slip ratio, further decrease of the wheel speed is restricted and the wheel speed turns to an increase soon and this cycle is repeated. Accordingly, there occurs no excessive drop of the wheel speed due to the response delay so that sufficient braking force is generated.

  • Patent number: 5946274
    Abstract: When an inclination switch SW3 is turned on by inclining a wristwatch 12 up at 12 o'clock within a predetermined time after an acceleration switch SW2 is turned on in a state where an auto mode on/off subswitch SW1-1 is on, a lighting circuit lights up an electroluminescence panel EL and puts off same automatically after a predetermined time has passed. If the auto mode subswitch SW1-1 is off, there is no possibility that the panel EL will be lighted up even when the user makes a motion to look at the time displayed on the wristwatch. As a result, the panel EL is not recklessly lighted up excluding by the user's intended motion, useless power consumption is suppressed to prolong the life of a battery used.

  • Patent number: 5936914
    Abstract: In an electronic appliance equipped with a light emitting apparatus 30, a transparent sheet member 31 having a character, a pattern or other symbols is arranged on a front surface of a transmission type flat-shaped light emitting apparatus 32. A colored sheet member 33 is arranged behind this light emitting apparatus. Openings 21 are formed in the colored sheet member 31, the light emitting apparatus 32, and the transparent sheet member 33. These openings are communicated therethrough. A pointer shaft 19 and 20 of a gear train mechanism 17 for indicating a present time is penetrated through the openings. Hands 22 and 23 are rotatably driven above the transparent sheet member 31. When the light emitting apparatus 32 is turned OFF, the colored sheet member 33 can be observed through the transparent sheet member 31 and the transparent light emitting apparatus 32. Accordingly, the colored sheet member 33 may provide high-grade quality and decorative feelings.

  • Patent number: 4430545
    Abstract: A method for producing line pipe of high strength and high toughness by the submerged-arc welding process in which a welding wire containing 0.18-0.55% C. is used, Ti or B or both are added to the welding wire or flux or both, and a steel containing 0.005-0.06% C. is welded by the submerged-arc welding process, whereby both Ti and B are caused to be present in the weld metal.

  • Patent number: 4115675
    Abstract: A method for heating steel pipe for induction heating coils, while the pipe is travelling through said coils in the axial direction, which comprises:(a) calculating the limit absorption electric power density Po (W/cm.sup.2) by the followng formula:Po = 1/40 x T x .sqroot.dwhere T = heating temperature (.degree. C) and d = wall thickness (mm);(b) attaching a power supply of low frequency to the induction heating coils;(c) setting said power supply for maximum capacity to be impressed to said induction heating coils, and(d) heating the steel pipe as it is travelling through said induction heating coils heated by said power supply, at such speed as to permit the steel pipe to be heated to the desired temperature, and heating the steel pipe with the set power if the absorption electric power density P by the set power is P .gtoreq. Po, and heating the steel pipe by shortening the effective length of the induction heating coils to obtain P .gtoreq. Po if P .ltoreq.

  • Patent number: 3979231
    Abstract: A method for producing a large diameter steel pipe having excellent shape, toughness and tensile strength by subjecting the pipe to descaling and to heat treatment which involves heating the steel pipe locally successively from one end to the other end of the steel pipe in the axial direction and forcedly cooling the pipe, and then expanding the steel pipe after the heat treatment.
