Title: Four-wheel steering device
Inventor: MATSUSHITA MASAAKI
IPC: B62D103/00
Filed: 1989-10-31
Abstract: PURPOSE:To prevent rear wheels from being abruptly changed in the steering direction at the time of acceleration and/or deceleration by computing the steering angle ratio of front wheels to rear wheels in response to vehicle speed conditions and acceleration/deceleration conditions, determining the target steering angles of rear wheels based on the aforesaid steering angle ratio, and thereby steering to control rear wheels. CONSTITUTION:A vehicle 2 is equipped with a main steering means 8 steering front wheels 10 and a steered means 12 steering rear wheels 14 in or anti-phase with the front wheels 10. The rear wheel side rack pinion mechanism 26 of the started means 12 is driven by an electric motor 32, and the electric motor 32 is concurrently controlled by a control means 34 based on respective detected signals from a vehicle speed sensor 40 and a front and a rear steering angle sensor 36 and 38. In this case, the control means 34 first computes the steering angle ratio of front wheels 10 to rear wheels 14 in response to vehicle speed conditions and acceleration/deceleration conditions, and secondly determines the target steering angles of the rear wheels 14. Following that, the rear wheels 14 are stopped so as to be controlled in such a way as to be of the target steering angle.

Abstract: PURPOSE:To handle plural BG screens without increasing the load on a computer device side by giving priority to each of the BG screens and controlling them, and taking the respective screens out and processing them. CONSTITUTION:Pictures of a balloon, mountains, and sea are assigned to respective backgrounds (BG) 0-2; and the BG 3 is not used and the part of the BG 0 except the balloon is made transparent. Denoting the priority levels of the BGs 0-3 as P0-P3, P0=4, P1=3, P2=0, and P3=0 when the screens are put one over another. In this case, the priority levels of the BG2 and BG3 are 0, so they exert no influence upon the superimposition screen; and the BG0 is higher in priority than the BG1, so the plane of the BG0 is in front of the plane of the BG1. The part of the BG0 except the balloon, however, is transparent, so the picture of the plane BG1 except the balloon is displayed as it is. When the balloon is moved, the balloon is never hidden behind the mountains since the priority of the plane BG0 is higher.

Abstract: PURPOSE:To attain the stabilized control of temperatures by varying the gain of an amplifier circuit which amplifies the difference between the output of a temperature detecting element and the reference value in accordance with the difference of temperature between both ends of a Peltier element. CONSTITUTION:A single end of a Peltier element 1 forming a temperature controller is thermally connected to a controlled system 4 enclosed by a heat insulating part 5 via a heat sink 2. While the other end of the element 1 is thermally connected to heat dissipating part 3. The temperature of the end at one side of the element 1 is detected by the 1st temperature detecting ele ment 6 and the temperature of the other end of the element 1 is detected by the 2nd temperature detecting element 7, respectively. These detected tempera ture detecting parts 8 and 9. Here the outputs of both parts 8 and 9 undergo subtraction through a subtractor circuit 10. Then the gain of a variable gain amplifier 12 is decided in response to said output undergone the subtraction. Thus the gain of the amplifier 12 is increased when the output value of the circuit 10 is positive and increased. As a result, a large amount of current flows to the element 1 for absorption of heat as the temperature of the open air rises up.
