Filed: 1983-04-13
Abstract: PURPOSE:To prevent an error code, which indicates heavy trouble information, from being deleted by the error code which occurs frequently and indicates light trouble information, by eliminating automatically the display operation of an error log to which deletion is designated. CONSTITUTION:A maintenance service processor 1 is connected to a data processor (CPU) 2. Normally, trouble information from the CP2 is converted in a converting part 13 each time and is stored in an error log table 11c, and the error code which is displayed is replaced with this trouble information, and this trouble information is displayed on a display device 14 through a register 15. When an input part 16 is operated to designate deletion of the displayed error code, a control part 10 registers this error code in a deletion register table 11d and accesses an error log table 11c to set a flag of register deletion. Further, the control part 10 traces back addresses in order to display the error code, for which the flag is not set, on the display device 15. Thus, light troubles whose deletion is designated are eliminated automatically, and high-operability useful error code display is possible.

Title: Driving and aligning mechanism for belt seal
Inventor: YATANI YASUNOBU
IPC: B41K1/10
Filed: 1995-02-27
Abstract: PURPOSE: To perform clearly laterally aligned prints by providing protrusions at a constant pitch at a corresponding position between the prints on the rear surface of an endless print belt provided with character prints at a constant interval. CONSTITUTION: Protrusions 6 are provided at a constant pitch on a corresponding rear surface between character prints 2 on the rear surface of an endless print belt 3 having the prints on a front surface, and a flat part between the protrusions 6 is equalized to the width B of a push plate 5.

Since this is conducted at each belt 3, the prints of each row are conducted according to the positions of the protrusions 6. Since engaging recesses 7 engaged with the protrusions 6 are provided on the front surface of a drive roller 4, the belt 3 can be effectively rotated without slip.

Filed: 1995-02-28
Abstract: PURPOSE: To improve the containing performance of the feeder to an application equipment by adding a polarized wave synthesis circuit comprising a synthesizer and a phase shifter to a circularly polarized wave branching feeder so as to use the resulting feeder as a linearly polarized wave feeder. CONSTITUTION: When a linearly polarized wave transmission signal is given to orthogonal output terminals 131, 132 of a transmission band polarizer 13, the signal is received in the inside of a reception band polarizer 12 and the transmission band polarizer 13 as an orthogonal linearly polarized wave, it is converted into a circularly polarized wave through a 9 deg. polarizer 11 and it is outputted from a common input output terminal 101. Conversely when an orthogonal circularly polarized wave reception signal is given to the common input output terminal 101, the signal is converted through the 90 deg. polarizer 11 into an orthogonal linearly polarized wave, and it is given to the reception band polarizer 12, in which orthogonal polarized wave signals are separated and they are outputted to orthogonal output terminals 121, 122.  Polarized wave synthesis circuits 20, 30 for reception and transmission bands are provided in a circularly polarized wave branching feeder 10 inputting/outputting the circularly polarized wave signal as above. The polarized wave synthesis circuit 20(30) is made up of a phase shifter (δ) 21(31) and a hybrid synthesizer (HYB) 22(23) respectively. Thus, the antenna feeder is used for a linearly polarized wave feeder.

Title: Cam plate type drive mechanism, cam plate type reduction gear and cam plate type axial piston pump device
IPC: F04B9/02
Filed: 1992-03-23
Abstract: PURPOSE:To provide cam plate type drive mechanism highly reliable in uniform speed performance with little vibration and noise while being desirable in assemblage, and provide an axial piston pump device and a reduction gear using this drive mechanism. CONSTITUTION:When an input shaft 4 is rotated, a cam plate 6 is also rotated, so that a driven plate 18 is rotated while oscillating with inclination alpha to an output shaft 11. This torque is transmitted to drive pins 26 and further transmitted through compression springs 25 so as to drive the output shaft 11 in the decelerating state. At this time, the inclination, to the output shaft 11, of a cam plate inner surface ring part 6a with which the protruding part 26b of the drive pin 26 comes in contact is alpha/2, so that power transmission points, that is, the spherical head part centers 26a of two drive pins 26, always exist on a plane bisecting the inclination alpha. Torque transmission between the input shaft 4 and output shaft 11 is thereby performed at uniform speed. Also, since the inclination alpha/2 is determined at the cam plate 6, uniform speed transmission can be performed positively.

Filed: 1980-05-15
Abstract: PURPOSE: To accurately prevent wheels from slipping off in a rubber endless tracked belt for a crawler running device and make the weight of the endless tracked belt lighter by providing the engagement holes of driving wheels in the concave of at the center of the endless tracked belt main body with a concave cross section and setting both the nongrounding surface of a core bar and the endless tracked belt contact surface on the same surface.  
     CONSTITUTION: The central drum 13 of the floating driving wheel 3 and the floating trank roller 4 is positioned at the center of the side drum 14 which performs frictional transmission. The depth of the central concave 7 in the endless belt 1 in which the central drum 15 is inserted becomes deep only for the projected height of the projection 15 provided in the endless belt 1. Besides, the anti-contact area 10' of the core bar bottom wall 10 is positioned almost on the same plane as the main body contact area 1'. This can increase the depth and prevent the wheels from being removed without decreasing the anti-engagement force in the concave 8'. Since each projection 15 is reinforced at the reinforced part 18a of the core bar 8, durability is improved and the oscillation absorption performance is also excellent in its elastic characteristics even if the projection 15 consists of the same elastic material as the endless belt 1.

Abstract: PURPOSE:To correct a shift in convergence position independently by using 1st and 2nd lenses which have the most negative and most positive power surfaces than any other negative and positive power surfaces of other lenses in the subscanning surface of a scanning optical system and moving and adjusting the 1st or 2nd lens in the optical-axis direction. CONSTITUTION:One of lens groups constituting a 2nd optical system includes the 1st lens 6 which has the most negative power lens surface among negative lens surfaces of respective lenses constituting the lens group and the 2nd lens 7 which has the most positive power among lens surfaces with positive negative power of the respective lenses constituting the lens group and is different from the 1st lens. The 1st lens 6 and 2nd lens 7 are provided movably in the optical- axis direction. Either of the 1st lens 6 and 2nd lens 7 is moved independently in the optical-axis direction, and then high sensitivity to a convergence position is obtained and the convergence position can be shifted greatly with an extremely small movement quantity. Consequently, the shift in convergence position can be corrected independently without entailing performance deterioration.
