Title: Tilt controller
Inventor: TAKAMINE KOICHI
IPC: G11B7/095
Filed: 1996-02-22
Abstract: PURPOSE: To always control vertically an orthogonal relation between an information surface of an optical disk and an optical axis of a light beam by changing a control target value of a tilt control means based on a pulse width fluctuation signal according to the fluctuation in a pulse width of an information reproducing signal. CONSTITUTION: A pulse width fluctuation detector 5 detects deviation in an edge between an RF pulse signal PRF and a reproduction reference clock, and outputs the pulse width fluctuation signal PD according to the deviation amount. A target value variable circuit 6 outputs a correction signal for changing a target value of a tilt servo to a tilt control circuit 9 according to the values of the signal PD and an orthogonal deviation signal TLE. A tilt sensor 7 outputs the deviation in the orthogonal relation between an optical disk 1 and the optical axis of the light beam 3 to output it to the circuit 9 through an orthogonal deviation detector 8. A slope mechanism 10 is controlled by the signal TLE and the correction signal from the circuit 9, and maintains the orthogonal relation between the disk 1 and the optical axis of the beam 3.

Title: Microfilm copying method
Inventor: NAKAMURA MITSUO
IPC: G03G15/22
Filed: 1980-03-19
Abstract: PURPOSE:To reduce the time required for copying by feeding a film independently from a moving table by means of the feed rollers of a carrier integrated with the moving table. CONSTITUTION:A microfilm M is set by the projected image of the mark (m) of the image A of one frame (f) of the film M in a screen. When a copying command signal is applied, a moving table is fed backward by a backward clutch by way of a moving table driving control circuit 100. When a leading end detector 73a optically detects the leading end of the image A, the moving table stops. Thence, the moving table is moved at the speed synchronized with that of a photosensitive drum by a forward clutch via the circuit 100 whereby the copy of the image A is formed. When a trailing end detector 73c detects the trailing end of the image A, the moving table stops, and further the feed rollers 571, 572 of a carrier 50 by a film feed control circuit 101 is controlled until the mark (m) of the image B is detected with a mark detector 59, by which the film L is moved independently from the moving table so that the next image B comes to the copying initial position, and the multiple images are copied in a short time.

IPC: F02B25/24
Filed: 1983-03-04
Abstract: PURPOSE:To prevent blow-through of new intaken gas by opening an opening/ closing valve, which operates in linkage with revolutions of the crank shaft, in such a timing as after the piston having opened the scavenging port, and thereby retarding the commencement timing of the scavenging stroke without requiring shift of the open position for scavenging or exhaust port from the arrangement according to conventional method.

Then a main 7 and an aux. 8 scavenging port open, when no scavenging stroke will begin because an opening/ closing valve 18 is closed. When the piston 4 reaches a point 140 deg. after the upper dead point, this opening/closing valve 18 opens, and the mixture gas compressed in the crank chamber 11 passages through a scavenging gas passage 14 and flows into the combustion chamber 5 from the main 7 and aux. 8 scavenging ports, to cause pressing-out of the combusted gas having filled the inside from the exhaust port 6.

IPC: G11B7/14
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To provide the optical head device with a high function capable of reproducing plural kinds of optical disks having their different substrates in thickness, although this optical head device is nevertheless miniaturized, simplified and equipped with one objective lens and one or plural optical module(s). SOLUTION: The polarizing optical element 9 consisting of a discoid transmissive area provided in a central part and a diffraction grating area having polarizing anisotropy provided on the outer side of this transmissive area and a 1/4- wavelength plate 10 are disposed in an optical path. At the time of reproducing the CD(compact disk) 11, a beam is restricted in its diameter in order to become a prescribed numerical aperture by virtue of this polarizing optical element 9 and is incident upon an objective lens 5 for the DVD(digital video disk) 6. As a result, a good convergent spot is formed on a recording surface of the CD 11 by using even this objective lens for the DVD 6. On the other hand, return light reflected by the disk is transmitted as it is through the polarizing optical element 9 because its polarizing direction is turned at 90 deg. by the 1/4-wavelength plate 10.  Consequently, the CD can satisfactorily be reproduced without shading of the return light beam attending upon displacement of the objective lens.

Inventor: MORIYA MIKIO
IPC: B41J1/34
Filed: 1986-02-20
Abstract: PURPOSE:To prevent unsteadiness of rotational speed and thereby achieve printing action free from dispersion and with satisfactory printing quality by employing feed load torque effectively as a control torque on a type drum through connection of a feed cam to the shaft of the type drum. CONSTITUTION:The force of a paper feed spring 40 is accumulated by rotating a paper feed lever 30 across a printing section through fitting of a follower pin 44 fixed on an arm 42 of the paper feed lever 30 to the external circumference of a paper feed cam 26. At that time, a one-way clutch 38 performs a slip action resulting in the holding of recording paper 22 at a prearranged position. A ribbon feed spring 58 is fitted between a ribbon lever 54 and a frame upper plate 56. While a ribbon feed lever 46 is driven by a ribbon feed cam 28, a ribbon lever 54 is gradually driven to rotate to accumulate the force of the ribbon feed spring 58. During accumulation of the force of the cam 28, this load torque acts as a direct control torque on a type drum 12, thus preventing unsteadiness of rotary speed along with the load torque of the cam 26.
