Abstract: An electronic mail server apparatus used for sending and receiving electronic mail reduces a load thereof. The electronic mail server apparatus includes a registration unit (a delivery destination information registration unit) that registers instruction information notified from a delivery destination apparatus (client PCs) of the electronic mail, and a notification unit (a communication unit) that notifies the delivery destination apparatus of incoming information in response to the instruction information in the registration unit when the electronic mail comes in. The notification unit sends received electronic mail in response to delivery request from the delivery destination apparatus, and inhibits sending of the electronic mail to the delivery destination apparatus before incoming information is sent out.

Abstract: A substrate and an elastomer are bonded each other, and then, a ditch is formed at the bonded surface of the substrate or the elastomer to constitute a flow channel and thus, to constitute a minute flow channel device with the flow channel. Then, a through-hole functioning an inlet and/or outlet is formed at the elastomer so as to be communicated with the flow channel. Then, a convex or concave joint is formed at the elastomer with integration so as to be opened outward from the through-hole so that the inclination angle of said joint is set to not less than 45 degrees and less than 90 degrees. Then, a joining device is pressed and joined with the minute flow channel device via the joint. Therefore, the connection for injecting and discharging a substance such as fluid or gas can be easily realized and automatized, and the device exchange can be performed easily.

Abstract: A cantilever for a scanning probe microscope comprises a lever section and a probe section disposed near the free end thereof. The probe section includes a conical distal end portion having a narrow point angle and a bulging proximal end portion continuous with the distal end portion. The cantilever is manufactured by utilizing a semiconductor process.

Abstract: An FET sensor apparatus comprising a sensor, a base member, and a support. The sensor comprises a semiconductor substrate having a predetermined crystal plane, a field-effect transistor formed on the semiconductor substrate, and a gate portion arranged on at least one of the major surfaces of the semiconductor substrate. The base member has a through hole in which the field-effect transistor is fitted. The support supports the sensor in the through hole in watertight fashion, with said gate portion exposed through an end of the hole.

Abstract: An optical sensor for detecting a specific substance in a solution, based on optical changes, includes a substrate and a thin membrane formed on the substrate. The membrane is formed of an ion complex material of an ionic amphipathic compound with a polymer having ionic groups of the opposite electrical charge, a potential-sensitive dye and a substance-selective compound.
