Title: Orientation setting device for on-vehicle equipment
Inventor: KUSANO MASAHIRO
IPC: B62D1/18
Filed: 1991-02-08
Abstract: PURPOSE:To perform high-precise fine adjustment of orientation of on-vehicle equipment without accompanying feeling of tardy action. CONSTITUTION:When a movement indicating signal S1 or S2 is fed to a drive control part 4 from a manual switch means 1, the drive control means 4 decides the position of on-vehicle equipment from a signal Stheta from a position detecting means 3 to detect the position of the on-vehicle equipment. The control means 4 sets a delay time responding to the position of the on-vehicle equipment. After a lapse of a set delay time starting from a time when a movement indicating signal is generated by the switch means 1, a drive means 2 is driven to start movement of orientation of the on-vehicle equipment. Thus, when the switch means 1 is shifted from ON to OFF in a short time, the on-vehicle equipment can be moved by a time shorter than the ON and OFF time, and highly precise fine adjustment is carried out without accompanying feeling of tardy action.

Title: Passage opening/closing device
Inventor: KAWAKUBO MASAAKI
IPC: F24F13/14
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent a door from being moved on the closing side by a fluid flow, and bring the relation between a swing angle and the opening of an opening portion so as to be close to having a linear characteristic, in a device which opens/closes an opening portion to become a fluid passage with a folding type door. SOLUTION: In a state where an opening portion 52 is entirely closed, a first board 61 and a second board 62 have specific angles θ1, θ2 with respect to a line B which is perpendicular to a fluid flow direction A. Therefore, fluid impinges at an angle on the two boards 61, 62 even in a small opening region where the opening portion is almost entirely closed. Therefore, rotating moment on a rotation shaft 64 produced by fluid flow becomes smaller than in the past, whereby it is possible to prevent the two boards 61, 62 from being moved on the closing side.  Further, since the first board 61 swings in a range excluding a region where the change amount of the opening to the swing amount of the first board 61 is small (angle θ1≈0), it is possible to bring the relation between the swing angle of the first board 61 and the opening closer to having a linear characteristic than in the past.
