Title: Vehicular automatic steering gear
Inventor: KAWASHIMA MITSUNORI
IPC: B60W30/00
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from running off a travel track even if driving wheels slip in the course of automatic steering control. SOLUTION: A memory unit 23 has a travel track memorized as a relationship of a standard steering angle θref with respect to a vehicle V travel distance X, which is calculated from the output of a rear wheel rotation angle detecting means S3 for detecting the number of revolutions of rear wheels Wr , which are follower wheels, and a control unit 22 steers front wheels Wf by actuating an actuator 7 on the basis of the standard steering angle θref retrieved from the travel distance X. The travel distance X error can be kept small even if the front wheels Wf , which are the drive wheels, slip during automatic steering control because the rear wheels Wr , to which drive torque is not transmitted, hardly slip.  Thus the travel track set as a relationship of the standard steering angle θref with respect to the vehicular V travel distance X becomes accurate and the vehicle V is prevented from coming off the travel track.

Title: Pipe with spiral fin
Inventor: YANOSU BODASU
IPC: F28F1/36
Filed: 1983-04-05
Abstract: A helicoidally finned tube for use mainly in heat exchangers. The tube comprises a cylindrical tubular member which carries or is integral with a helical member the turns of which form the fins of the tube. The fins are provided with ripples which extend from the outer rim of the fins inwardly and the depth of which diminishes toward the tube center. The ripples serve for diverting a cooling medium inwardly to hotter parts of the tube thereby improving its heat transfer performance. The helicoidal member has rippled sections alternately with level sections, the rippled sections subtending an angle not exceeding about 90 degrees and both types of sections on successive turns registering with one another in the direction of the axis of the tubular member. The spacing of the sections is substantially equal to a quarter of the circumference of the tubular member so that the rippled sections of the helicoidal member occupy diametrically opposed positions on the tubular member, the ripples being disposed generally transverse to the direction of airflow. The ripple-free sections, thus positioned, facilitate removal of impurities precipitated in the fin gaps (FIG. 9).

Filed: 1988-03-11
Abstract: PURPOSE:To reduce time and labor required for control of colors with no waste of forms and the color toner by performing the copying actions for correction of colors on the same form. CONSTITUTION:Various types of color correction are applied to the picture data read out of a picture memory means 201 and these corrected data are copied on the same form at different positions in a single print process. Here an operator can select a picture containing a color closest to an original picture FD or a picture containing the operator's preferable color out of the pictures included in the noted areas EA of different colors and copied on a single sheet of form. Thus the operator can easily control the colors. Then a picture containing a prescribed blank area is produced by a picture selecting circuit 402 which inhibits the production of pictures in a prescribed area of the picture FD. Thus the picture read out of the means 201 is formed in said blank area and the synthesization of pictures is carried out. Thus it is possible to perform the control of colors with no waste of the forms and the color toner.
