Abstract: A user registers information in searcher information storage in advance. Database creators register provision conditions of information in provision condition storage as a rule for defining information granularity. When a query request is received from a user terminal, a search request is sent to each database. Query results from the each database are acquired, and information to be provided into a form at an appropriate information granularity is sent to the user terminal. A third party may register disclosure restriction information. In this manner, a search mediation system capable of controlling information to be disclosed according to the searcher who wants to access to the information is provided.

Abstract: The ablation threshold of a laser fluence with respect to the surface of a sample manufactured in a high vacuum chamber is determined by using the sample. The quantity of vacancy-type defects is determined by radiating a laser beam having a fluence slightly higher than the ablation threshold on the surface. At the same time, the quantities of adatom-type and kink-type defects are determined by radiating a pulsed laser beam having a fluence slightly lower than the ablation threshold on the surface repeatedly to obtain the relation between an emission yield and the number of laser pulses. The quantity of the adatom-type defects is obtained by determining the area (total quantity of emitted atoms) of a rapidly decreasing portion of the relation. The quantity of kink-type defects is obtained by determining a magnitude of an emission yield of a slowly decreasing portion of the relation.

Abstract: A recording device performs recording by reciprocating a carriage mounting a recording head by a stepping motor. The recording head includes a rotation position detector for detecting a rotation position of a rotor of the stepping motor, a controller for performing closed-loop driving of a switching timing of an exciting current of the stepping motor according to a detection signal from the rotation position detector, and a motor speed control circuit for controlling a rotation speed of the stepping motor according to the detection signal from the rotation position detector. The device performs stationary confirmation whether the switching timing of the stepping motor is normally performed via the controller.
