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).

There is provided a keyboard structure capable of preventing a fingernail of a user from being inserted between key tops and achieving uniform illumination without illumination leakage. A key top body portion (120a) and an upper sheet (120b) are integrally formed to form a key top (120) and a flange portion (120d) is formed by protruding the upper sheet (120b) from the key top body portion (120a) toward an outer circumferential direction. A frame (122) is disposed between the adjacent key tops (120) and a gap is closed by the flange portion (120d) of the upper sheet (120b) and a flange portion (122a) of the frame (122).

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.
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 key switch structure is provided whose waterproofing property is improved without affecting a contact of a membrane sheet. The upper surfaces of the membrane sheet, the embossed part and the circumferential bend part of a back plate are formed on one and the same plane, and a thermal sheet is welded to those upper surfaces. The thermal sheet comprises a thermally meltable, adhesive sheet, which will be heated and pressed with heat rollers to be welded to the upper surfaces. The back plate has an air vent hole formed in its bottom portion.

The cloning source of an authorized receiving device cannot be identified. A key distribution system 1 concerning the present invention includes: a communication channel 10; a key distribution center 11; a server 12; and receiving devices 13a to 13n. The key distribution center 11 distributes, to the server 12, the information necessary for distributing shared keys SK to the receiving devices 13a to 13n, and distributes the individual information group EMMG necessary for receiving the shared keys SK from the server 12. The server 12 generates the shared keys SK, generates the common information ECM based on the shared keys SK and the system secret variable group set SPGS, and distributes the common information ECM to the receiving devices 13a to 13n. The receiving devices 13a to 13n obtain the shared keys SK based on the individual information group EMMG and the common information ECM and outputs them to outside.
摘要:
In order to accurately measure a shape feature of a minute droplet arranged on a substrate by a simple method, with respect to the droplet, the substrate is perpendicularly irradiated with laser light to cause diffracted light fluxes generated during passage of the laser light through the droplet to interfere with each other, so that a diffraction pattern is obtained. The diffraction pattern formed on a screen of a detector as an image is picked up by an image pickup apparatus. The shape feature of the droplet is measured by using the resultant diffraction pattern and a refractive index of the droplet.
