Abstract: PURPOSE:To prevent a document conveying failure by driving either a contact glass or a guide member according to the direction of conveyance, thus automatically varying the relation between the position of the contact glass and that of the guide member. CONSTITUTION:Each of guide plates 43 and 44 has an upper plate-shaped portion guiding a document 18 and forming an inclined face that gets higher in the direction for conveying the document 18, and the right end of the guide plate 43 is in a position higher than a contact glass 12A opposite thereto and the left end of the guide plate 44 is in a position lower than the contact glass 12A opposite thereto, so that a difference of height is formed therebetween.

Title: In-tank fuel pump
Inventor: MUKOUYA AKIYOSHI
IPC: F04D13/06
Filed: 1987-05-07
Abstract: PURPOSE:To always obtain the stable action of rotation, by forming the bottom end face of a rotary shaft in the armature of a fuel pump into plane shape and the upper face of a thrust receiving member into protrusion shape. CONSTITUTION:A thrust receiving member 28, driven and fixed to a pump cover 13, forms the upper face protrusion into a spherical shape. On the contrary, a rotary shaft 10 of an armature 19 forms its bottom end face into a plane shape. Since the thrust receiving member 28 continually comes only in its spherical face point end into contact with the rotary shaft 10 even when its center A in the armature 19 is positioned deflecting from the spherical face center of the thrust receiving member 28, it applies no force in a direction at a right angle with the axial direction acting on the plane-shaped end face of the rotary shaft 10, thus it performs always the stable motion of rotation.

When an auto-handler control apparatus 5 receives auto-handler operation starting from the control apparatus 1, an auto- handler 6 is operated to set an object to be tested to the pin electronics 3 in a testable manner and, when setting operation is finished, it informs termination to the system control apparatus 1. When correcting operation starting is received, timing correcting operation is carried out and, when it is finished, the information of termination is carried out with respect to the control apparatus 1. By this method, timing preciseness can be kept extremely high.
