摘要： In an electric power steering system, a d.c. motor is drivingly connected to a steering shaft with a steering for generating an assisting power to rotate the steering shaft. Independently of an alternator for charging a battery, a d.c. generator driven by a vehicle engine is dedicated for supplying an electric power to the d.c. motor. A control circuit is responsive to a signal representing a manual torque applied to the steering and reads out one of objective values from a memory. The control circuit is further responsive to a fed-back signal indicative of a load applied to the d.c. motor and controls electric current flowing across a field coil of the d.c. generator in such a manner that the difference between the read-out objective value and the fed-back signal becomes zero.

A flow dividing valve serves to divide the pressure fluid of a constant flow rate in a predetermined ratio into first and second flows which are respectively directed to the servo-valve and reaction device. The predetermined ratio is varied such that the flow rate of the fluid supplied to the reaction device increases as the pressure of the fluid supplied to the fluid motor increases.

The seamless steel pipe may contain a specified amount of one or more element(s) of V and Nb, and/or a specified amount of one or more element(s) of Ca, Mg and REM. The seamless steel pipe can be produced at a low cost by adapting an in-line tube making and heat treatment process having a high production efficiency since a reheating treatment for refinement of grains is not required.

摘要： A tab (51) of a male terminal (50) is inserted into a main portion (11) of a female terminal (10). The tab (51) contacts a contact portion (16) of a resilient contact piece (15) to connect the female and male terminals (10, 50) electrically. A guiding portion (18) is formed on an inner surface of the main portion (11) for guiding the tab (51) inserted into the main portion (11) to a position where the tab (51) contacts the contact portion (16). The guiding portion (18) extends from a position before a contact position of the tab (51) with the contact portion (16) to the contact position while being inclined with respect to an inserting direction of the tab (51).

摘要： An input device, wherein the screen (18a) of a display device (18) is divided into two regions, a region (A1) and a region (A2), and the icon switch displayed in the region including the position of an invisible pointer (P′) is selected. Thus, one of an icon switch (1) and an icon switch (2) that are displayed on the screen (18a) is selected at any time. Consequently, the user will no longer have to watch the screen carefully and perform an operation for moving an instruction marker such as a visible pointer to a desired icon switch, for example as in conventional devices. Accordingly, the user can enter a desired instruction in a short time by selecting a desired icon switch in a short time.
