An electronic parts installing socket capable of downsizing an electronic device by reducing the height of socket projecting from one surface of the printed circuit board comprises a socket housing fitted into a socket inserting hole. The socket inserting hole penetrates from a front surface to a rear surface of a printed circuit board. Also, a plurality of contacts each having contact pieces disposal on the socket housing and project from a side surface of the socket housing. The contact pieces are connected a contact connecting pattern which is positioned at an opening edge portion of socket inserting hole. Front surface shielding members and are connected to the printed circuit board to shield a portion projecting to the front surface of the printed circuit board. A box shaped rear surface shielding member covers a portion projecting from a rear surface of the printed circuit board to the socket housing and is connected to the front surface shielding members.

An electronic part-mounting socket includes a socket body having an electronic part-receiving portion for receiving an electronic part, and a plurality of contacts having a resilient contact piece portion projecting into the electronic part-receiving portion, and the electronic part is connected to a printed wiring board via the contacts. The socket body includes outer casing having a bottom plate and a contact holding member that is detachably received within the outer casing, and holds the contacts. Each of the contacts includes a board contact piece portion projecting from a lower surface of the contact holding member so as to be held in contact with the printed wiring board, and the printed wiring board is held between the bottom plate and the contact holding member.

The connector for a flexible board is equipped with a housing, a plurality of contacts, and a cover. The plurality of contacts are placed so that their contact parts are in two rows along opposing inner wall surfaces of an insertion concavity of the housing. By inserting a pressure-applying part of the cover into the insertion concavity, a flexible printed circuit board (FPC), which has been guided between the cover and the insertion concavity, is pushed in and deformed and held sandwiched between the cover and the insertion concavity, and each contact part of the FPC comes into contact with the contact part of the corresponding contact. The number of contacts capable of being housed within the connector is increased two-fold from that of prior art connectors and the number of contact parts in the flexible board is increased two-fold. Furthermore, operation of the connector is easier.

A heat sink substrate comprises a Cu—Mo composite substrate composed of a molybdenum (Mo) green compact with which Copper (Cu) of 20-60 wt % is impregnated. It is preferable that the heat sink substrate is a rolled plate obtained by repeatedly warm rolling or cold rolling the Cu—Mo composite substrate and that the rolled plate does not include any fine void and unevenly impregnated copper, that is, copper and molybdenum are uniformly distributed therein.

A classification processing unit is disclosed for use with a computer having a register for storing classification data items and for storing data items respectively associated with the classification data items. The classification processing unit includes a comparator for receiving the classification data items from the register, which has an array of comparator units, each unit having a reference value for comparison with the classification data items. The processing unit also includes a classification pipline having an array of classification units respectively associated with the comparator units. The classification pipeline receives data items respectively associated with the classification data items and stores the data items respectively associated with said classification data items into the register in response to trigger signal from the comparator. The processing unit further has a counter provided for each of the classification units to count the number of data items that are stored by the processing unit.

In a through-the-cannula catheter placement system, a catheter is used which comprises a body portion and a tip portion at one end of the body portion. The body portion has a double-wall structure. The outer wall is a tube of pliable, nonthrombogenic material. The inner wall is a reinforcing tube of a material having sufficient resilience to avoid collapse during use. The tip portion is also made of a pliable nonthrombogenic material. The tip may be an extension of the outer wall.

A socket for mounting on a substrate includes a terminal exposure part that exposes the plurality of substrate connection terminals of the contacts at lower opposing edges of the socket, and a central part that includes a bottom surface bulging part that protrudes downwardly to define a bottom surface of the socket housing. An insulative contact support board that houses the contacts is housed inside a thickness of the bulging part. A bottom surface of a substrate connection terminal of the contacts supported by the contact support board is exposed at the terminal exposure part. A bottom surface bulging part is inserted into a housing bottom mating hole formed in the connection substrate, and the substrate connection terminal is connected to a pattern terminal provided on the upper surface of an edge of the housing bottom mating hole.
