摘要:
A vacuum drier apparatus capable of preventing the thermal deformation of the protection member as well as scattering of the tempered glass plate in a case of an accidental breaking of the tempered glass plate. The apparatus includes elastic supporter members located between the glass plate and the protection member, for supporting the glass plate and the protection member with respect to each other, such that the glass plate can be pressed tightly to seal off the opening section of the vacuum drying space, while the protection member can be pushed away from an edge of the front side of the opening window by an external pressure exerting on the protection member. The protection member is preferably a transparent plastic plate in an outwardly curving dome-shaped form.
摘要:
A multi-axis laser machine in which the working efficiency can be improved even when machining positions in respective systems are different from each other. The positioning operation of a laser positioning unit for positioning an optical path of a laser beam in an axis and the positioning operation of another laser positioning unit for positioning another optical path of the laser beam in another axis are performed independently of each other. An arbitration unit monitors the laser positioning units as to whether they have finished positioning or not. The arbitration unit operates a deflection unit (AOM) so as to supply the laser beam to one of the laser positioning units which has finished positioning. Incidentally, when the laser positioning units finish positioning simultaneously, the arbitration unit supplies the laser beam to the laser positioning units in a predetermined sequence.

There are disclosed a solder bump forming method and an apparatus therefor, which achieve a high reliability, and an electronic part, produced by this method and this apparatus, is also disclosed. For each of the step of arraying solder balls, the step of supplying a flux, and the step of mounting the solder balls on a board, it is checked whether or not any solder ball is omitted, and the process is conducted while confirming the condition of the operation, thereby enhancing the reliability and also preventing defective products from being produced.
摘要:
An upper substrate that has upper conductive layer formed on a bottom surface thereof, is bonded to lower substrate, that has lower conductive layer opposed to the upper conductive layer with a predetermined space held therebetween, on a top surface of lower substrate by an adhesive layer that is made of a thermoplastic resin containing a tackifier dispersed therein, with a bonding property of the adhesive layer being enhanced by pressing. Addition of the tackifier increases flexibility of the adhesive layer and performs bonding with a large adhesive area at pressing. Thus, a width of the adhesive layer can be as small as approximately 1 to 1.5 mm. This can provide a smaller touch panel ensuring a predetermined touch sensitive area.

Provided is a dew condensation-free touch panel. Touch panel (200) has first transparent substrate (21) and second transparent substrate (22). First transparent substrate (21) has main surface (21a) provided with first transparent conductive film (23). Second transparent substrate (22) has main surface (22a) on which water vapor transmission preventive layer (40) as dew condensation prevention part, and second transparent conductive film (24) are provided in this order. Touch panel (200) has two regions: visible region (26a) and invisible region (26b) with region boundary (26) between them. Water vapor transmission preventive layer (40) is formed at least in visible region (26a). First transparent substrate (21) and second transparent substrate (22) are fixedly bonded to each other via adhesive layer (31) in invisible region (26b) or in the periphery of touch panel (200) so that first transparent conductive film (23) and second transparent conductive film (24) can have a predetermined distance therebetween.

Disclosed is a synthetic resin emulsion powder obtained by spray-drying a composition that comprises an emulsion (A) where the dispersoid is a polymer that having one or more unsaturated monomer units selected from ethylenic unsaturated monomers and dienic monomers, and a polyvinyl alcohol (B) having, in the molecule, from 1 to 12 mol % of ethylene units. The emulsion powder has good redispersibility and good water resistance. Its redispersion well form good films and has good storage stability at low temperatures. The emulsion powder is favorable for additives to hydraulic substances, as it well disperses in hydraulic substances such as cement mortar and gives hardened articles of high mechanical strength. The emulsion powder is also favorable for joint materials for hydraulic substances, as its adhesiveness and durability are both good and gives jointed articles of high mechanical strength.
摘要:
The touch panel has a light-transmissive upper substrate, a light-transmissive lower substrate, and a bonding layer. The lower surface of the upper substrate is formed thereon with an upper conductive layer. The top surface of the lower substrate is formed thereon with a lower conductive layer facing the upper conductive layer with an air gap. The bonding layer is formed on at least one of inner edges of the lower surface of the upper substrate and the top surface of the lower substrate, and additionally has an open groove communicating with the air gap. The makeup provides a touch panel reliably operable with a simple structure.

摘要:
The present invention provides an electronic apparatus including a touch pad. The electronic apparatus also includes a housing and a mechanical acoustic transducer. The housing supports an outer circumferential portion of the touch pad via a suspension to provide a space for sound emission between the housing and the touch pad. The electromechanical acoustic transducer is connected to the housing, and emits sound into the space. When the electromechanical acoustic transducer emits the sound into the space, an energy of the sound emitted causes the touch pad to vibrate and thereby to output sound outside the electronic apparatus.
摘要:
A method of machining the contour of a printed circuit board by effecting a relative feed movement between a rotating tool and the other periphery of the printed circuit board. The electrical current value of a drive motor for driving a spindle to which the tool is attached is detected and an operation is conducted for changing the machining condition in such a manner as to reduce the electrical current value of the spindle drive motor and, at the same time, for changing also tool diameter compensation amount to a value corresponding to the machining condition after the change, at every time the detected electrical current value has reached a predetermined current value immediately before tool breakage and repeatedly by a predetermined number of times.
