A light emitting device has a light emitting element and an adhesion layer to bond the light emitting element to a mounting member. The adhesion layer is of inorganic material particles and a transparent inorganic binding layer to be formed between the neighboring inorganic material particles, and the inorganic material particles are substantially connected with each other in the adhesion layer. Another light emitting device has a light emitting element and a phosphor layer that radiates fluorescent light while being excited by light emitted from the light emitting element. The phosphor layer is of phosphor particles and transparent inorganic binding layer to be formed between the neighboring phosphor particles.
摘要:
A POS terminal apparatus is adapted to be connected to an external device. With an application running in the POS terminal apparatus, a device manager determines whether the external device is capable of counting a first value indicating a usage amount of the external device, and if so, the device manager acquires the first value from the external device in response to a first command from the application. A counter retains a second value indicating the usage amount of the external device and notifies the second value to the application in response to a second command from the application. If it is determined that the external device is not capable of counting the first value, the counter virtually counts the second value in accordance with a third command sent from the application to the external device. An updater updates the second value with a third value which is obtained by a fourth command from the application. The first value is retained even when the second value is updated with the third value.
摘要:
A simplified control system provides a uniform interface to a Java-based POS application. A new interface defining a method SetEntry for passing an entry point to a database to a device service object is created in the device service object which loads this interface as a rule. This allows greater freedom designing the device service object and makes it possible to write better service objects. Device service objects for other manufacturers and other types of devices can also be loaded by a shared factory class, and a simpler JavaPOS system can be provided at low cost.

A membrane electrode assembly (11) for a tube-shaped fuel cell, which is provided with a tube-shaped solid electrolyte membrane (1); an outside catalyst electrode layer (2) formed on an outer peripheral surface of the solid electrolyte membrane (1); an inside catalyst electrode layer (3) formed on an inner peripheral surface of the solid electrolyte membrane (1); an outside collector (4) arranged on an outer peripheral surface of the outside catalyst electrode layer (2); and an inside collector (5) arranged on an inner peripheral surface of the inside catalyst electrode layer (3), is characterised in that at least one of the outside collector (4) and the inside collector (5) is a coiled collector that includes a coiled conductor.
摘要:
A memory card socket structure includes a case having a card accommodating portion for receiving a thin plate-shaped memory card, and a contact block having contact terminals to be brought into contact with terminals of the memory card. The case has a cover shell and a base shell both formed of metal plates, and the cover shell and the base shell are welded to each other by a laser welding.
摘要:
A heater for fusing toner images onto recording paper is provided. The heater includes a supporting base that has an upper surface and a lower surface. The base has a relatively low thermal conductivity. The heater also includes a heating element formed on the upper surface of the base. A heat conductor is provided on the upper or lower side of the base. The heat conductor has a thermal conductivity greater than the thermal conductivity of the base.
摘要:
An ordinary-temperature purifying catalyst includes an oxide having an oxygen defect introduced by a reduction treatment, and a noble metal loaded on the oxide. For example, the oxide can be at least one oxide selected from the group consisting of cerium oxides and zirconium oxides, at least a part of which has an oxygen defect. The catalyst can purify an environmental loading material, such as carbon monoxide, a nitrogen oxide, ethylene, formaldehyde, trimethylamine, methyl mercaptan and acetaldehyde, in air at an ordinary temperature. A method for how to use the catalyst is also disclosed.
摘要:
A thermal printhead 1 according to the present invention includes a multiplicity of heating elements 4a formed in a row on an obverse surface of an elongated substrate 2 at a portion which is offset widthwise toward one longitudinal side of the substrate, and a protective film 8 formed on the obverse surface of the substrate 2 at the widthwise offset portion for covering the heating elements 4a. The protective film 8 is formed to extend on the obverse surface of the substrate 2 continuously from the widthwise offset portion onto one longitudinal side surface 2a of the substrate. A longitudinal edge 8b of the protective film 8 directed toward the other longitudinal side of the substrate 2 is tapered.
