Abstract: A line segment of two-dimensional data is input through an input device 1 such as a mouse, and is then temporarily stored in a storage device 10 as well as being displayed on a two-dimensional display screen 2a. The line segment of two-dimensional data is converted to three-dimensional data when it obtains information in the depth direction based on its relationship to another line segment that constitutes a 3D graphics and has three-dimensional data already. Three-dimensional data of line segments that have that data in addition to two-dimensional data are stored in a storage device 7, and are projected by a projection conversion circuit 11 onto a two-dimensional projection plane that has been set by a visual field input device 8, so as to be converted to two-dimensional data, which are then displayed on the display screen 2a. Therefore, the line segments that have already been converted to three-dimensional data are displayed on the display screen 2a together with the line segments that have been input through the input device 2 and still have only two-dimensional data. An operator can construct a 3D graphics constituted of three-dimensional line segments simply by inputting two-dimensional line segments as if he were sketching. This provide an apparatus and method in which an operator can input a three-dimensional graphics to a graphic system by performing an operation that is as if he were sketching on a paper surface.

Abstract: An integrated circuit has an oscillator (18) for generating a plurality of phases of an oscillator clock signal (CLK1, CLK2, CLK3, CLK4). Each phase of the oscillator clock clocks a respective one of a plurality of ring shift registers (30, 32, 34, 36). The output (44) of each stage of the ring shift registers is a phase of a desired clock signal and is an input to a multiplexer (38, 46, 48, 50, 52, 54, 56, 58) than can selectively provide one of the desired clock phases as the output of the multiplexer (42, 74, 76, 78, 80, 82, 84, 86). In another embodiment of the invention the ring shift registers generate half of the phases of a desired clock signal at a multiple of the desired frequency. The multiplexer output clocks a divide by two circuit which is followed by another level of multiplexing to generate the other half of the phases and to divide down to the desired frequency.

Abstract: An engaging part provided on a loader which has shifted a holder carrying thereon a disc cartridge to a reproducing/recording position, engages with a mechanical lock mechanism so as to release a holder pin in said mechanical lock mechanism from its locked condition in order to hold a movable chassis in a floating condition with respect to a stationary chassis. On the contrary, the engaging part on the loader locks the holding pin in the mechanical lock mechanism so as to fix movable chassis to the stationary chassis when the holder has been shifted to the cartridge ejecting side. When the holder is moved to the reproducing/recording position, the holding pin provided on the holder engages with a shutter closing spring so as to retract an engaging part at the front end of the shutter closing spring through an opening in the holder in order to prevent the disc cartridge from making contact with the shutter closing spring, thereby it is possible to make the feeling of insertion of the disc cartridge satisfactory, and to avoid damaging the disc cartridge. Further, a rack in a loader feed mechanism is composed of two rack members which are linked together so as to decrease the operating length for moving the loader is reduced.

Abstract: The present invention relates to a production process and a production apparatus for the optical information recording media 3 comprising a material thin film 1 which exhibits a reversible change of the optical characteristics by the irradiation of an energy beam such as a laser beam 4 from the laser light source 7 on the substrate 2. By having a means to dropping the emission strength instantly to the virtual zero level after having the emission for a specified time (shutoff circuit portion 10) in conducting the initial crystallization process, both a large irradiation power and a short irradiation time can be achieved to reduce the various thermal damages. Since the method does not waste electric energy, the time to complete recharging of the electric energy for the next discharge emission can be shortened. Further, by having a means to maintain a great difference between the applied voltage and the charging voltage (storage circuit 8 and trigger circuit 9), recharging time can be further shortened to facilitate the treatment speed of the initializing process. Further, in the production process of optical information recording materials with single side structure, in particular, by applying an annealing process in combination with a formation process of the resin protection layer or a recording thin fil initialization process, the warp or distortion of media caused by the contraction of the ultraviolet ray curing resin layer or the recording thin film layer can be reduced or corrected to realize an optical information recording medium having excellent servo characteristics. Further, by having at least one of two media to be affixed with a transmissivity of an ultraviolet ray of 3 % or more as a method to comprise an optical information recording medium with double sides structure not liable to have a warp or distortion, an ultraviolet ray curing resin can be used as an adhesive, resulting in simplifing the production process.

When a ratio at which the output time of the developing agent presence state of the detecting sensor occupies in the predetermined time range is equal to or less than a predetermined value, the determining device determines that the residual amount of developing agent is small, and when the ratio is substantially equal to 0, the determining device determines the absence of developing agent.

Abstract: In a production process of a cellulose acetate which comprises (a) a reduced pressure-acetylation step of acetylating a cellulose under a reduced pressure in the presence of sulfuric acid or other acidic catalyst, with distilling off a gaseous phase component of the reaction system out of the system, and (b) a post-acetylation step of allowing the acetylation to further proceed by increasing the pressure as compared with the pressure of the reduced pressure-acetylation step by means of release of the pressure reduction of the reaction system or the like, the shift operation from the reduced pressure-acetylation step to the post-acetylation step is conducted by taking a distilling rate of a distillate in the reduced pressure-acetylation step as an index to control the reaction temperature of the post-acetylation step. The shift operation from the reduced pressure-acetylation step to the post-acetylation step may also be conducted by taking a distilling rate after the distilling rate in the reduced pressure-acetylation step has reached a maximum value.

Abstract: Low voltage operational amplifier (10) operates in a voltage range of one to eight volts over a temperature range of 0° to 70° centigrade. Op amp input stage (12) uses N-channel depletion-mode MOSFETs to provide amplification of the differential input and maintain constant transconductance. Source follower MOSFET (13) provides unity gain in transferring the AC signal, STAGE-1 OUTPUT, to the base of current sinking transistor (18). Sink control circuit (14) and source control circuit (22) create the base drive current in transistors (18) and (24). Dependent on the input signal the AC signal path on SINK PASS THROUGH signal controls op amp output sink transistor to sink current or through current steering circuit (16) causes SOURCE PASS THROUGH signal controlling op amp output source transistor to source current. An output stage provides approximately fifty milliamps of current drive and is quiescent until the output driver is selected.
