Abstract: A pants garment has a pair of thigh leg members for covering the thigh area of a wearer. A front thigh elastic band member is provided substantially at a front side of each of the thigh leg members and extends obliquely from an upper front portion to a lower front portion of each thigh leg member. A back thigh elastic band member is provided substantially at a back side of each of the thigh leg members and extends obliquely from an upper back portion to a lower back portion of each thigh leg member. The garment also has a front and back crus elastic band members extending obliquely on crus leg members, which cover the crus areas of the wearer.

Abstract: The invention relates to the hairpiece to be attached to a cap removably. The clothing material of the hairpiece is implanted with hairs in width corresponding to the wearing angle of the different cap. The hairpiece is provided with the attachment for catching the cap and attaching the clothing material to the cap removably.

Abstract: A system for diagnosing evaporation control system failures repeatedly introduces pressure, positive or negative, into the evaporation control system and closes up it hermetically, a plurality of times (for example two times), and detects changes in internal pressure in the evaporation control system. An average value of the internal pressure changes is compared to a threshold value so as to judge whether there is leakage of fuel vapors of the evaporation control system. When a difference between the internal pressure change is greater than a specified value, the evaporation control system failure diagnosis is interrupted.

Abstract: An air-fuel ratio control system for an engine, to which evaporated fuel in a canister is supplied, is used for feedback controlling an air-fuel ratio based on a feedback control value calculated according to the quantity of evaporated fuel supplied to the engine. A calculation is made, in a first range of engine operating conditions, of a difference of a first control value between the first control value determined during supplying of the evaporated fuel to the engine and the first control value determined during not supplying of the evaporated fuel to the engine in the first range. A second control value for a second range of engine operating conditions is established different from the first range based on a feedback control value for controlling an air-fuel ratio of fuel in the first range, a ratio of the quantity of intake air into the engine between the first and second ranges, and a ratio of the supplying quantity of the evaporated fuel into the engine between the first and second ranges.

Abstract: In order to check four-wheel steering characteristics of a four-wheeled vehicle provided with a four-wheel steering system in which both the front wheels and the rear wheels are turned in response to operation of the steering wheel according to preset four-wheel steering characteristics, the steering wheel is turned to turn the front wheels and the rear wheels, and the actual turning angle of the front wheels and the actual turning angle of the rear wheels are measured, thereby detecting the actual relation between the turning angles of the front and rear wheels. Whether the actual four-wheel steering characteristics of the vehicle deviates from the preset four-wheel steering characteristics is determined through comparison of the actual relation between the turning angles of the front and rear wheels with the preset four-wheel steering characteristics.
