Title: Optical pickup
Inventor: NISHII KANJI
IPC: G02B7/28
Filed: 1983-01-25
Abstract: PURPOSE:To improve controlling characteristics and to reduce the size of an optical pickup by making current flow into an elastic supporting member of a lens barrel in the diameter direction, winding a coil around the lens barrel to form a gap of magnetic flux crossing the supporting member and the coil, and adjusting focus and tracking. CONSTITUTION:When a current is made to flow into the supporting member 14 in the direction shown by I1, electromagnetic force is applied in an X-X direction between the magnetic flux components of gaps in tracking magnetic circuits 15, 15', so that the supporting member 14 is elastically displaced in the X-X axis direction. Consequently, the lens center of a diaphragm lens 4' is moved to control the tracking. If a current is made to flow into a focus coil 9, electromagnetic force is generated in the Z-Z axis direction in the gap magnetic flux of a focusing magnetic circuit 13 and the supporting member 14 is moved in the Z-Z axis direction to control the focusing. Consequently, the moment due to the tracking driving force is not generated in the lens barrel 6' and the force direction coincides with the displacement direction so that unrequired displacement is not generated and proper controlling characteristics are obtained.

Title: Man-machine interface system
Inventor: UKITA TERUHIKO
IPC: G06F15/00
Filed: 1986-01-22
Abstract: PURPOSE:To realize natural conversation by referring to an input format forecast list to analyze input information in the forecast analysis mode only when it cannot be analyzed in the normal analysis mode. CONSTITUTION:This man-machine interface consists of an input part 1, an input interpreting part 2, a conversation control part 3, a task processing part 4, a response generating part 5, and an output part 6. If an input format of input information can be forecasted in accordance with a generated system response, the response generating part 4 generates preliminarily an input format forecast list and gives it to the input interpreting part 2. The input interpreting part 2 refers to this list to interpret input information including ambiguity. If the analysis processing of input information in the normal analysis mode fails, the analysis processing in the forecast analysis mode is performed. Thus, a user can input freely information without being restrained by the system response, and the conversational performance is improved.

Title: Processing method for silver complex salt diffusion transfer
Inventor: TSUBAKII YASUO
IPC: G03C8/06
Filed: 1985-01-23
Abstract: PURPOSE:To reduce the dependency of an alkali activating soln. used for processing on processing conditions and to provide high suitability to running processing by using an alkali soln. having a specified composition contg. a phosphate, amino-alcohol and a water soluble polymer as the alkali activating soln. and a replenisher to be supplied to the soln. CONSTITUTION:An alkali soln. contg. 0-0.13mol/l M3PO4 (where M is an alkali metal), >=0.5mol/l amino-alcohol and a water soluble polymer enough to adjust the soln. to 3-20cps viscosity at 20 deg.C is used as an alkaline activating soln. for silver complex salt diffusion transfer and a replenisher to be supplied to the soln. Since the alkali activating soln. contg. not developing agent used as a processing soln. in a developing stage and the replenisher have a lower phosphate content and a higher amino-alcohol content and contain the water soluble polymer thickener, the superior characteristics of the fresh processing soln. can be maintained for a long period without exchanging the processing soln. in a processor.

Abstract: PURPOSE:To smoothly execute the clamping and releasing of a die and to reduce the driving force by introducing hydraulic oil into a hydraulic chamber, abutting upper inclining face of a wedge on lower inclining face of a projection, swinging a holding claw and clamping the die. CONSTITUTION:The working oil is supplied into the hydraulic chamber 21 to retreat a piston 22, and by bringing the wedge 23 into contact with the inclining face 20a of projection 20, a piston 18 is pushed up to push up rear end part of the pushing claw 13 through a semi-spherical projection 19. The holding claw 13 pushes up a ram 8 upward by a stroke S and is swung to counter-clockwise and holding part in the die is intensely held with end part 13c of the holding claw 13. At this time of clamping, the wedge 23 intensely holds the inclining face 20a of projection 20, and as the friction force is acted but the working oil is supplied into the hydraulic chamber 21, the working oil achieves role of lubricator to reduce the friction force. Therefore, output of the hydraulic source for working the piston 22 may be low.

Title: Copying device
Inventor: ADACHI KOJI
IPC: G03G15/01
Filed: 1987-01-23
Abstract: PURPOSE:To perform an copying operation at every color by making light incident on an image reader through a filter in a 1st scanning and directly in a 2nd scanning, and extracting a specified color component. CONSTITUTION:When the signal of a red component passed through a red filter 5a is read in the 1st canning, the signal is stored in a memory 52 temporarily. This 1st scanning is for the storage of the red signal 45b and a photosensitive drum 9 does not rotate. Then when the 2nd scanning is started, the photosensitive drum 9 begins to rotate, a 2nd electrostatic latent image begins to be formed by an image formation optical system 7, and the image reader 5 starts the reading of reflected light incident directly from an original simultaneously. The read signal of the image reader is stored in the memory, so as scan need not be made more than once. Consequently, transfer to a copying form needs to be performed only once, a copy having high picture quality is taken, and the high picture quality can be maintained at the time of enlarged or reduce image copying operation.
