Title: Guide rail for conveyor of magnetic levitation type
Inventor: NODA AKITAKA
IPC: B65G54/02
Filed: 1986-03-25
Abstract: PURPOSE:To keep the stable levitation running of a conveyor, by forming and composing the shapes of joint sections so that either one of guide rails may be positioned within the distance of a specified dimension from a surface confronted with a gap sensor between the joints. CONSTITUTION:By the guide rail 20 of a conveyor of magnetic levitation type, end surfaces 21a, 21b inclined at an angle alpha to the lower surface of a guide rail 20b are respectively formed at end sections confronted with adjacent respective guide rails 20a, 20b. When a gap between the guide rails 21a, 21b is set to be G, then a relation between the angle alpha and a gap g3 on the passing of a sensor 8 through the gap G is shown by g0<g3<g0+Gtanalpha, and the output range of the sensor 8 coping with the gap is selected to be within a firm control range. As a result, the variation of the gap of the conveyor passing between joint sections can be reduced, and the stable levitation running of the conveyor can be kept.

Title: Image forming device
Inventor: TAKEDA MASAMI
IPC: B41J23/02
Filed: 1993-03-02
Abstract: PURPOSE:To provide an image forming device which can prevent the photosensitive layer of the surface of a photosensitive drum from being peeled by frictional force generated between the layer and an abutting roller provided on a developing sleeve. CONSTITUTION:The developing sleeve side is disposed so as to be freely moved with a supporting point 6 as the center. According as driving force transmitted to a driving gear 17 from a driving source 16 is increased and attenuated, a sleeve gear 13 is moved between a position where it is brought into contact with the tip part of the gear top of a drum gear 14 and a position where it is meshed with the gear 14. Thus, the abutting roller fitted to the developing sleeve is moved to be close to and away from the surface of the photosensitive drume.

Title: Delay circuit
Inventor: SATO YUTAKA
IPC: H03K5/13
Filed: 1995-02-28
Abstract: PURPOSE: To eliminate the need for adjustment of timing between a pulse signal and delay data, to attain on the fly at a high speed and a stable delay operation. CONSTITUTION: Before a selector 9 receives inputs 301-304, any of AND gates 1-4 gets through with delay data outputted from a decoder 7 and any of the inputs 301-304 passes through an OR gate 5 and a pulse signal is outputted therefrom resulting from any of outputs 311-344. Delay data 421-424 fed to the AND gates 1-4 are selected at a trailing edge of the input 304 whose arrival time is most delayed. That is, after a delay element 10 for a pulse signal is selected, delay data for a succeeding pulse signal are selected, then same delay data are being fed to the AND gates till the pulse signal passes through the AND gates. Thus, stable operation is warranted.

Filed: 1990-03-15
Abstract: PURPOSE:To maintain a rule even by a user, not knowing rule expression inherent to a system, without correcting an inference method by providing a production schedule planning means to effect inference of a production schedule and plan the schedule by using a pattern rule corrected by a room maintenance means. CONSTITUTION:A specified pattern rule needing addition and variation is read from an acknowledge base by means of rule maintenance means 12 to display it on a CRT 11b of a user interface 11. Thereafter, by adding and varying a necessary variable part as the displayed pattern rule is watched, an acknowledge base is corrected. Meanwhile, a production schedule planning means 16 previously handles a production plan as one rule at each of patterns 1, 2,...n and effects inference on the assumption that the given spot of a pattern rule has a variable part. Therefore, a production schedule can be inferred and planned by using a corrected pattern rule by the rule maintenance means 12 without especially correcting an inference method.

Title: Ic sucking conveyance device
Inventor: KIYOKAWA TOSHIYUKI
IPC: B25J15/06
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To reduce the cost greatly without requiring a buffer device when compared with a ball screw by constituting a vertical driving means by a motor, a pulley, and a winding spring. SOLUTION: By rotating a coil spring 34B in the direction in which it is reeled out from a pulley 34A by a motor 34, an absorption head support member 33 and an IC sucking head 10 descend along a linear guide 31 due to their self-weight. Even of the motor 34 continuous to rotate in a condition in which an IC sucking face 11 of the IC sucking head 10 is in contact with a top face of an IC 1 to be sucked, the coil spring 34B is merely deformed by bucking, and driving force of the motor 34 is not transmitted to the IC 1. Consequently, the IC 1 is not broken, even if a buffer device is not provided between the sucking heat support member 33 and the IC sucking head 10.  Moreover, even of power failure occurs in a condition in which the IC sucking head 10 is at a descent position, the coil spring 34B can wind up the sucking head 10 to an upper position by its own wining force during power failure.
