Title: Beam shutter for invisible laser
Inventor: IWASAKI TAKASHI
IPC: B23K26/066
Filed: 1984-05-14
Abstract: PURPOSE:To prevent the burn of a reflecting member by providing a shutter in the course of a invisible laser beam and disposing the reflecting member which reflects the visible laser beam from the other light source. CONSTITUTION:A shutter blade 15 is freely oscillatably attached to the oscillating shaft 13 of a rotary solenoid 11 and a beam damper 21 having cooling water pipes 17, 19 is provided to one end thereof. A rectangular prism 25 is mounted to the damper 21. A CO2 laser beam which is invisible light irradiates a work through the circular hole 33 of a frame 9 when the blade 15 is rotated to the left. The positioning of the beam is executed by turning the shutter blade 15 to a horizontal position via a spacer 29 and a shock absorber 31 then the CO2 laser beam is shut off by the damper 21 and the visible light is entered from a direction Y to irradiate the work through the prism 25. The burn of the reflecting member such as the prism 25 is prevented by the above-mentioned method.

Title: Current limiting reactor
Inventor: ARINOBU HIROYUKI
IPC: H02H9/02
Filed: 1982-05-31
Abstract: PURPOSE:To easily make a reactor adaptable to various rated currents such that the impedance is reduced during the feeding of the rated current and increased at the time of occurrence of an excessive current, by a construction wherein a plunger is supported by a return spring, and the plunger is driven to be attracted into a coil by the magnetic force of the coil when the excessive current occurs. CONSTITUTION:A current limiting reactor is connected in series to wiring lines (not shown) through a terminal unit 19, and a coil 8 serves as an electric line element. The illustrated state represents the normal state where the rated current is fed. At this time, since the resilient force of a return coil spring 25 is stronger than the plunger attracting force (magnetic force) caused on the coil 8, the plunger 22 is held in a chamber 24. Thus, the current limiting reactor has an impedance value based on the hollow coil. This make it possible to set the impedance relatively small for feeding of the rated current.

Filed: 1988-04-19
Abstract: PURPOSE:To prevent unnecessary vibration, etc., and to attain high-speed access by so fitting a supporting tool that plural plate springs may be parallel to each other and their width directions may be parallel to the level face of a carriage and supporting rotatably a rotor loaded with an objective lens in the face parallel to the carriage by the supporting tool. CONSTITUTION:Plural plate springs 6a-6d are so fitted on a fixing tool 4 fixed on a carriage 5 that they may be parallel to each other and their width directions may be parallel to the level face of the carriage 5 and may be extended perpendicularly to the transfer direction of the carriage 5 and a single supporting tool 7 is fitted on each end of the plate springs 6a-6d. A rotor 8 loaded with an objective lens 3 to converge light beams on an optical disk is supported rotatably in the face parallel to the face of the carriage 5 by the supporting tool 7. Thus, even when the rotor operates in order to adjust focus, the unnecessary vibration or the change of posture does not occur in the rotor and the high-speed access is attained.

Title: Device for monitoring movement of paper near paper inserting gage in sheet offset printing machine
Inventor: HERUMUUTO EMURITSUHI
IPC: B65H7/08
Filed: 1992-04-15
Abstract: PURPOSE: To ensure a time for a sheet paper to settle on lay marks even at a high printing speed by preparing and setting the timing of a running detecting instant for sheet monitoring, and switching of the device between two running detecting instants according to the working state when the printing cylinder is in operation. CONSTITUTION: In the printing-on state the second sensing time is provided at an angle B for sensing a sheet on the lay mark. The angle B is further delayed, the sheet is to have a longer time (interval X-B) to stay on the lay mark. The sensing on the lay mark or the sampling time is delayed so that sheet movement can stop reliably even at the maximum printing speed. A sheet is sensed at time (angle) A or B according to the state of the printing press.

Title: Image display apparatus
Inventor: MASUDA MITSUYA
IPC: H04N9/12
Filed: 1981-06-18
Abstract: PURPOSE:To enable an interlace display to be easily performed with an apparatus, which can display color TV images on a plate-like displayer by use of electron beams, and obtain a beautiful display by providing an interlace electrode in front of or in back of the vertical deflection electrode of the said apparatus. CONSTITUTION:The output of a judging circuit 40, which judges whether the field is an odd field or an even field from a horizontal synchronizing signal, has inverse polarity which canges for every field. The output of the circuit 40 is applied to conductive plates 42 and 42' of an interlace electrode 41. For example, if the plate 42' is positive and the plate 42 is negative during the time of an odd field, the beam location coincides with a full line. On the other hand, if the plate 42' is negative and the plate 42 is positive during the time of an even field, the beam location coincides with a broken line. Consequently, an interlace can be carried out easily only by adding the interlace electrode 41.

Title: Control method of servomotor
Inventor: NAKAYAMA HIDESUKE
IPC: G05D3/12
Filed: 1979-07-27
Abstract: PURPOSE: To enable accurate positioning at all times, by producing a torque balanced with stationary load with the time integration of deviation and zeroing the deviation.  
     CONSTITUTION: The value set to the objective position set section 4 and the position signal from the position detector 2 attached to the servomotor 1 are compared and the deviation is converted to a voltage at the deviation generator 5. This voltage is given to the integrator 6 for time integration. Although the integrator 6 is operated when the stationary load torque exceeds the motor torque to the deviation, the signal at this time is given from the deviation detector 10. The output of the integrator 6 is greater while the deviation is present and when the deviation is zero, the output of the integrator at that time is held and balanced with the stationary  load. This holding is made at the hold circuit 7 with the timing signal fed from the  deviation detector 10. Accordingly, when the circuit 7 does not hold the output of  the integrator 6, the output is given to the post stage as it is.
