Abstract: PURPOSE:To prolong the life of an air dynamic pressure bearing type light deflector setting a rotary member containing a rotary polygon mirror at a non-vertical attitude. CONSTITUTION:A dynamic pressure air bearing is provided on the bearing of a drive mechanism of the rotary member 1 having the rotary polygon mirror 11, and when the air dynamic pressure bearing is in a state other than a vertical attitude, a center axis Y-Y in the horizontal direction of a stator core 7 is made eccentric by DELTAd downward in the vertical direction for the center axis X-X in the horizontal direction of the rotary member 1 by an amt. canceling force corresponding to gravity of the rotary member 1 expressed in terms of an axis inclination angle in the vertical direction and magnetic unbalance force generating eccentricity between a rotary magnet 6 and the stator core 7. Thus, contact force and contact time on the bearing are reduced and the wear in the bearing is reduced.

IPC: B41J19/18
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To simplify a mechanism, to reduce power consumption and to surely execute a capping operation of an ink head in terms of an ink jet printer wherein a cap is brought into contact with an ink ejection nozzle by virtue of a driving force of a carrier. SOLUTION: In the case where a movement target position of a carrier is designated by a printing control means (SH), a motor-torque-high-sequence wherein a driving torque of a carrier motor is increased is executed (S14) when the movement target position is in a cap operation region. In the case where the movement target position is out of the cap operation region, the motor- torque-high-sequence is executed (S14) when the present position of the carrier is in the cap operation region, but a motor-torque-normal-sequence wherein the carrier motor is controlled by a normal driving torque is executed when the present position of the carrier is out of the cap operation region (S15).

Title: Magneto-optical disk
Inventor: HASHIMOTO SHUICHI
IPC: H01F10/28
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To improve performance and productivity by forming recording media and protective films after discharging the moisture in substrates to the max. possible extent by heat treating these substrates at and for an adequate temp. and time. SOLUTION: The substrates consisting of a polycarbonate resin are heat treated for 2 to 6 hours at 100 to 120 deg.C. For example, a released gas rate (q) is proportional to t<-1> (t=discharge time) when the substrates are heat treated for two hours at 120 deg.C. The released gas rate (q) is proportional to t<-0.83> in the heat treatment for two hours at 80 deg.C. Then, the moisture remains in the substrates and the drying is insufficient in the case of the latter but the sufficient drying is resulted in the former. The films of the magneto-optical recording media are formed in a vacuum state on the substrates after the removal of the moisture in the substrates.  The film formation is executed by subjecting a vacuum film forming system to a vacuum evacuation for the vacuum evacuation time determined by the heating conditions of the substrates and the number of the substrates to be formed with films, then forming the films of the magneto-optical recording media in the same manner as heretofore and, in succession, forming the protective films. As a result, the disks having the good performance are obtd, with the high productivity.

Title: Printing hammer actuation mechanism
Inventor: SATO REIJI
IPC: B41J9/14
Filed: 1989-08-31
Abstract: PURPOSE:To rotate a printing hammer for printing toward a type by the restoring force of a hammer spring to perform an impact printing by a method wherein an unlock pawl is projected on the peripheral surface of a follower clutch, and an unlock lever which presses the rotating unlock pawl to laterally travel the follower clutch for disengaging ratchets from each other is provided in the rotating range of the unlock pawl. CONSTITUTION:A motor 14 rotates a drive clutch 7 and a follower clutch 6 in conjunction through intermediate gears 9 - 12to windingly rotate a printing hammer 3 up to a standby position against the resiliency of a hammer spring 5. In this standby state, a circular edge 15a of a reverse rotation preventing plate 15 bites a brake drum 11c to prevent the reverse rotation. When a motor switch is turned ON by the insertion of a printing card, the motor 14 again rotates in a winding direction, thereby depressing an unlock pawl 6b of the follower clutch 6 on an unlock lever 17 and separating a ratchet 6a of the follower clutch 6 from a ratchet 7a of the drive clutch 7. Then, the printing hammer 3 which has been windingly rotated powerfully rotates for printing toward a type face together with the follower clutch 6 by the resiliency of the hammer spring 5.

Filed: 1990-08-27
Abstract: PURPOSE: To optimize a pressure change by forming a rotor and a stator into a truncated conical or a hemispheric shape to provide variable control of a gap with the relative axial movement of the rotor relative to the stator during exhausting work. CONSTITUTION: A rotor 21 and a stator 22 are formed into a truncated conical or a hemispheric shape and in a symmetrical shape along an axis 23 of rotation. A gap 24 between the rotor 21 and the stator 22 can be modified by the axial movement and a dotted line shows different relative positions of the rotor to cause a smaller gap 24'. The movement is performed by an electromagnet, a fluid pressure or a mechanical device, for example. The gap can be adjusted as a function of the viscosity of a pure gas or the viscosity of a pumped up mixture.

Title: Ophthalmic measuring instrument
Inventor: NUMAJIRI YASUYUKI
IPC: A61B3/10
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary waiting time and to immediately start measuring again by cancelling processing when an examiner judges the failure of measuring. SOLUTION: The outputs of photo-multipliers 26a and 26b inputted to a system control part 27 are A/D-converted to be temporarily stored in an external storage device 32 one by one. After the lapse of a prescribed data fetching time, tracking and storing operation is finished and the part 27 executes first processing of calling only one channel of the outputs of the stored photo- multipliers 26a and 26b to give FFT processing and waveform-analyzing it by an incorporated arithmetic circuit to obtain a temporary cut-off frequency.  In the case where an examiner clearly judges defective fetching of data from the state of the observation of an eyegrond under measuring e.g. even without locking at the result of the first processing in this first processing, the examiner can cancell the first processing in the middle of it by pressing a cancelling switch 29 to immediately execute measuring again.

Abstract: PURPOSE:To eliminate an influence of unnecessary mechanical vibration on the oscillation frequency to lead out a stable oscillation frequency signal by forming a metallic case covering a dielectric resonator or the like into a block for an oscillator provided with the dielectric resonator. CONSTITUTION:A MIC (microwave integrated circuit) substrate 2 is placed on a discoid conductive substrate 1, and a dielectric resonator 4 attached through a quartz column 3 and an FET are connected by a micro strip line to form an oscillating circuit on the MIC substrate 2.
