摘要:
A key switch structure which enables a reduction in the width of the key switch. A key switch structure comprises a first support member (22), a second support member (23), and a third support member which are arranged independently of each other, the first support member (22) having rotation pins (22d, 22e) and slide pins (22a, 22b), the second support member (23) having rotation pins (23e, 23f) and a circular columnar slide section (23a), the third support member having front end sections (24d, 24e), which are slidably held, and a support shaft section (24a). A key top (21) is supported by the support members (22, 23, 24) so that the key top (21) can move in the vertical direction. The length of at least one side of each of the support members is set to be less than or equal to the mounting diameter of a rubber dome (27).

A wiring board including a first insulation layer, a conductive pattern formed on the first insulation layer, a second insulation layer formed on the conductive pattern and the first insulation layer and having an opening portion exposing at least a portion of the conductive pattern, and a connection conductor formed in the opening portion of the second insulation layer such that the connection conductor is positioned on the portion of the conductive pattern. The connection conductor has a tip portion which protrudes from a surface of the second insulation layer and which has a tapered side surface tapering toward an end of the tip portion.
摘要:
A method of manufacturing a semiconductor device and a semiconductor device including a first semiconductor element mounted on a first surface of a base plate, wherein solder balls are formed on a second opposite surface of the base plate-such that the second opposite surface includes an area without solder balls. At least one second semiconductor element is mounted to the base plate at the area of the second surface without solder balls. The at least one semiconductor element may be mounted to the base plate using low molecular adhesive, or in the alternative, high temperature solder.

A communication procedure has been developed that allows even a low-rate CPU to perform stable communication so as to realized wireless network nodes, which have a long communication distance and also have a long battery life. Each wireless network node decides its own time slot number by use of random numbers and transmits it after delaying the transmission by the number of time slots. When receiving the unique number from the wireless network node, a master unit transmits, to the wireless network node, an ACK signal together with the unique number. When receiving its unique number, the wireless network node gets into a sleep state for a period of time. In this way, each time communication is established, the number of active wireless network nodes is reduced.
摘要:
A cleaning method for cleaning a powder container by introducing a cleaning medium into the powder container from a first opening part of the powder container for attaching powder in the powder container to the cleaning medium and discharging the cleaning medium together with the powder from a second opening part situated opposite from the first opening part is disclosed. The method includes a step of releasing the cleaning medium from a position higher than the first opening part of the powder container.
摘要:
A semiconductor device is provided which has a semiconductor element having an element forming surface at which a sensor element is formed, a back surface on the opposite side of the element forming surface, and a light transmissive protective member laminated over the element forming surface via an adhering portion. The semiconductor device includes a region exposed from the protective member at the outer peripheral end portion of the semiconductor element, when viewed from the protecting member in a laminating direction.

A key switch arrangement is able to accomplish the compatibility with a normal keyboard in respect of profile without increasing the height of the keyboard and reduce the cost without adding new members for a light source. The key switch arrangement includes a key-top having an optically transparent key-top having a cutout letter part formed thereon, an optically transparent membrane sheet having a contact, an optically transparent plate member arranged under the membrane sheet, and a light source arranged in the membrane sheet. The light source emits light to pass the plate member and the membrane sheet to illuminate the cutout letter part on the key-top.
