An air blowing device and an air blowing system reduces a region where a person cannot be recognized in a space provided with the air blower, and achieves control of the air blower in view of a person in a larger range in the space. The air blower includes: a first sensor configured to detect a position of a human in a first human detection range; a receiver configured to receive a detection result of a second sensor transmitted from a transmitter of a sensor-mounted device, the sensor-mounted device including the second sensor configured to detect a position of a human in a second human detection range; and a controller configured to perform air blowing control when the first sensor does not detect a human in the first human detection range and the second sensor detects a human in the second human detection range.

A switch device includes: a first touch sensor portion to which one end of a first wiring portion is connected; a second touch sensor portion to which one end of a second wiring portion is connected; and a touch wiring portion having one end of which is connected only to the second wiring portion and the other end of which is open; the touch wiring portion being arranged such that when one capacitance is produced between the touch surface and the first wiring portion by a touch operation, the other capacitance is produced between the touch surface and the touch wiring portion by the touch operation; and the touch operation is disabled when detecting the one capacitance and the other capacitance. A finger touches a portion other than a touch sensor portion (wiring portion), and the touch is disabled, and thereby, a high reliability is achieved.

The present inventions are (A) a solvent comprising at least one cycloalkyl alkyl ether (1) represented by the general formula: R1&#x2014;O&#x2014;R2 (wherein R1 is cyclopentyl or the like; and R2 is C1-10 alkyl or the like); (B) a method of preparations the ethers (1) characterized by reacting an alicyclic olefin with an alcohol in the presence of an acid ion-exchange resin having a water content of 5 wt % or less. The solvent is useful as cleaning solvent for electronic components, precision machinery components or the like, reaction solvent using various chemical reactions, extraction solvent for extracting objective organic substances, solvent or remover for electronic and electrical materials, and so on. The process enables industrially advantageous production of the objective cycloalkyl alkyl ethers (1).

A leakage preventing system of confidential information, for example, for CBT (Computer Based Training), prevents leakage of highly confidential education and training information. The system includes a manager terminal unit having an authentication server, an educator/trainer terminal unit for holding confidential information for CBT in the encrypted form and operated by a specific user, and a communication network for exchanging from time to time data between these terminal units. Authentication is given to the educator/trainer terminal unit only when an authentication request from the educator/trainer terminal unit satisfies predetermined authentication granting requirements, and a prescribed limited using time is set so as to make it possible to peruse the confidential information decoded in the educator/trainer terminal unit, only within the limited time.

A dental implant including an engagement portion provided in a head portion to be engaged with an engagement member to rotate the parts, wherein the engagement portion is a hole having a lateral cross-sectional shape of double squares in which two squares with the same shape having a common central axis are superimposed at a relative angle of from 20&deg; to 45&deg;. By use of the dental implant, even when an engagement portion provided in a head portion to be engaged with an engagement member to rotate the parts is partly damaged by an excessive torque or the like at the time of operation once effected, it is possible to fasten again the parts with the screw and release the parts from the screw, and the operability during engagement with the engagement member is good.

Process for producing halogenated organic compound

An angled dental implant includes an implant fixture to be implanted into a hole formed in the mandible of the patient, an abutment having a truncated conical portion configured to be bolted to the fixture, a cylinder configured to engage the abutment, where the cylinder has a center line that is inclined relative to a longitudinal axis of the fixture, wherein the cylinder is fastened to the abutment with a bolt aligned with the center line of the cylinder.

Angled dental implant

A difference recording apparatus includes a log comparator, a processing unit, a recording unit, and a log update section. The log comparator detects a log difference by using a classification key in a log of input data. The processing unit restores the log by using difference data from the log comparator. The recording unit records the log restored by the processing unit. The log update section limits recording of a log of identical data in the recording unit within a unit time on the basis of the presence/absence of a difference detected by the log comparator and an upper limit of log acquisition.

An implant fixture is built up of a titanium body, a titanium cover that is threadedly engaged with the body, a support having a columnar form of protuberance to be loosely fitted into a small hole in the head of the cover, and a connector spring member including a cylindrical body having spring action that enables it to take hold of the outer surface of the cover through a flange provided at one end. A forceps is built up of two frames, each provided at one end with a finger ring having a claw and at the other end with a holding surface for holding a second shaft of the support in parallel with the axial direction, and a guide rod which extends axially from one frame and has a slidable weight.
