摘要:
An ink supplying and collecting apparatus includes a case, ink cartridges detachably attached to the case, and a collecting container detachably attached to the case. The ink cartridges supply ink to a recording head of a printer via ink supply tubes. The collecting container collects ink drained from the recording head via an ink drain tube. The case is located outside of and is separate from the printer. Thus, the sizes and shapes of the ink cartridges and the collecting container can be freely designed.

A leak rate measuring method measures a leak rate of a vacuum apparatus including a vacuum chamber in which an object is accommodated to be processed, a first gas exhaust pump connected to the vacuum chamber via a first valve serving as a conductance variable valve, and a second valve connected to a downstream side of the first gas exhaust pump in a gas flowing direction. In the leak rate measuring method, there is provided a circulating path branched from a gas exhaust path between the first gas exhaust pump and the second valve and connected to the vacuum pump to communicate therewith. The pressure inside the vacuum chamber is monitored by circulating a gas into the vacuum chamber through the circulating path with first gas exhaust pump under the condition that the first valve is set at a predetermined conductance and the second valve is closed.

An ink cartridge for an ink jet recording device, includes: a container having an ink supply port; at least two ink chambers partitioned in the container, one being located substantially in an upper section and the other being located substantially in a lower section; an ink suction passage connecting a bottom region of the lower section ink chamber to a bottom region of the upper section ink chamber; and a negative pressure generating mechanism provided to a flow passage connecting the upper section ink chamber to the ink supply port.

A first positioning mark is formed at four corners of the outer side of the display area of a front substrate at the same step as the step of forming transparent electrodes. The first positioning marks are made of the same material as the material of transparent conductive films and formed in the same layer as a layer in which the transparent electrodes are formed. A second positioning mark is formed at four corners of the outer side of the display area of a back substrate at the same step as the step of forming partition walls. The second positioning marks are made of the same material as the material of glass layers containing white pigments and formed in the same layer as a layer in which the partition walls are formed. The positioning of the transparent display electrodes as well as the partition walls are directly carried out.

While a voltage value of the battery detected by a battery voltage-detecting part is less than a predetermined threshold voltage value for determining a low voltage state, a rotation sensor malfunction-detecting part stops calculating a vehicle speed and uses the vehicle speed calculated at a time immediately before a time when a voltage value of a battery becomes less than the threshold voltage value for determining the low voltage state, for detecting malfunction in a rotation sensor. Thereby, even if noises due to a voltage fluctuation in the battery mix with the rotation signal from the rotation sensor, since the rotation sensor malfunction-detecting part does not calculate the vehicle speed during a period of time when the voltage value of the battery detected by a battery voltage-detecting part is less than the threshold voltage value for determining the low voltage state, the vehicle speed is not miscalculated based on the rotation signal including noises, and the malfunction in the rotation sensor can be precisely detected.

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.
摘要:
In an ink-jet type recording head including a nozzle plate provided with nozzle openings, a spacer provided with partitions for partitioning pressure generating chambers, ink supply ports and reservoirs, and a plate member sandwiched and fixed together. Displacement of the plate member is produced by piezoelectric vibrators to thereby generate ink droplets. The spacer is formed by anisotropic etching of a silicon single crystal substrate so that the pressure generating chambers, the ink supply ports and the reservoirs are formed as through-holes communicated with each other. Accordingly, etching conditions for the respective through-holes are made equal to each other. Particularly, through-holes small in sectional area such as the pressure generating chambers and the ink supply ports can be formed with a high accuracy.
