A method of designing an ophthalmic lens, including: determining specifications of a temporary lens to provide an optical power required by a wearer; applying the temporary lens to a prescribed schematic eye, and effecting emmetropization of an optical system including the temporary lens and schematic eye; obtaining an optical characteristic of the optical system at a position of an optical axis of the temporary lens which is offset from an optical axis of the schematic eye by an offset amount; obtaining successively optical characteristics corresponding to different configurations of the temporary lens with the axes of the temporary lens and schematic eye offset by the offset amount; selecting optimum one of the different configurations of the temporary lens which gives optimum one of the successively obtained optical characteristics; and determining specifications of an intended ophthalmic lens as a final product, based on the selected optimum configuration of the temporary lens.

Ink type information is read by a read and write system (62) from a semiconductor storage system mounted on ink cartridges (9a to 9d) attached to a cartridge holder (8). A decision control system (61) decides whether or not ink type information has already been stored in ink type storage system (63), and stores the ink type information thus read when the ink type information is not stored. In the case in which the ink cartridge is exchanged, the ink type information is similarly read and it is decided whether or not the same ink type information is identical to the ink type information stored in the ink type storage system (63). If they are not identical to each other, the operation of the recording apparatus is inhibited and a display system (68) is caused to display an error message thereon.

In an ink jet recording apparatus, a recording head is mounted on a carriage which reciprocately moves in a widthwise direction of recording paper. A subtank is mounted on the carriage for supplying ink. A main tank stores ink which is replenished to the subtank. An ink amount detector detects an amount of ink stored in the subtank. A replenishment controller controls replenishment of ink stored in the main tank to the subtank, in accordance with the ink amount detected by the ink amount detector.
摘要:
An ink jet recording apparatus wherein a sub-tank mounted on a carriage is replenished with ink from an ink cartridge as a main tank by the action of pressurized air from an air pressurizing pump. The ink jet recording apparatus is provided with means for opening an air flow passage from the air pressurizing pump to the ink cartridge into the atmosphere as a cover member of a cartridge holder is opened when the ink cartridge is attached or detached. The recording apparatus has an on-off valve unit for maintaining pressure on the air flow passage in a predetermined range and drive means capable of forcibly opening the on-off valve unit for releasing a pressurization state, for example, when the operation power of the recording apparatus stops. The recording apparatus further includes a diaphragm displaced upon reception of air pressure on the air flow passage and output generation means for generating a control signal based on the displacement amount of the diaphragm, and driving the air pressurizing pump is controlled by the control signal generated by the output generation means.

In a tube pump, a rotor is fixed to a drive shaft so as to rotate therewith. A tube pressing member is swingable in an axial direction of the drive shaft. A swinging member swings the tube pressing member in accordance with the rotation of the rotor. An upper outer face of a tube is fixed to a lower portion of the tube pressing member. A lower outer face of the tube is fixed to a fixing member. The tube is forcibly pressed and expanded in accordance with the swing motion of the tube pressing member, while the pressed/expanded part is shifted in an extending direction.

A high-strength synthetic fiber is fabricated in such a way that a fiber, such as a polyester fiber, nylon fiber, or polyether ketone fiber, is irradiated with an infrared beam and is drawn while its thread is heated and softened at temperatures higher than a glass transition temperature. An apparatus for fabricating a fiber is provided with a means (10) for continuously feeding a thread (1) at a constant feed rate (v) and an infrared irradiation means (13) including a laser for irradiating the thread (1) with an infrared beam, interposed between the means (10) for feeding the thread and a fiber winding means (11) for winding the thread (1) at a winding rate (V) higher than the constant feed rate (v), in order to soften the thread (1) traveling to be fed and wound.

A digital video camera includes an addition circuit in which an offset set by a CPU is added to an output from an A/D converter. A clamp level calculation circuit calculates a clamp level on the basis of an average level of eight pixels included in each line within a back end OB (optical black) level detection area in a normal mode, or calculates a clamp level on the basis of an average level of two pixels included in each line within a front end OB level detection area in a quadruplication mode. A first subtraction circuit subtracts the clamp level from an output of the addition circuit so as to clamp the output of the addition circuit. An output of the first subtraction circuit is clipped at a zero-level by a zero-clipping circuit, and an output of the zero-clipping circuit is applied to a second subtraction circuit through a low-pass filter, whereby the same offset can be subtracted from the output of the zero-clipping circuit.
摘要:
A cleaning blade which comes in elastic contact with a nozzle plate to clean a recording head is subjected to ink-receptive treatment on the surface thereof which comes in contact with the nozzle plate, such as formation of grooves or the like which can retain an ink by a capillary force. In this arrangement, an ink can be retained on the blade regardless of the rebounding of the blade shortly after the termination of cleaning operation, making it possible to prevent the ink from flying toward the recording head when the blade rebounds.

A fabrication method of a solid electrolytic capacitor is provided, which is able to form the surface irregularity of a conductive polymer layer serving as a solid electrolyte with good controllability and good stability. A capacitor body is formed by a valve metal. The body serves as an anode of the capacity. An oxide layer is formed to cover the surface of the capacitor body. The oxide layer serves as a dielectric of the capacitor. A first conductive polymer layer is formed on the oxide layer. The first conductive polymer layer serves as a part of a solid electrolyte of the capacitor. A powder of a conductive polymer is deposited on the first conductive polymer layer by spraying a fluid containing the powder on the first conductive polymer. A second conductive polymer layer is formed on the first conductive polymer layer to cover the deposited powder. The surface of the second conductive polymer layer has irregularities corresponding to the deposited powder. The second conductive polymer layer serves as another part of the solid electrolyte of the capacitor.
