A static electricity measuring system including a probe, a measuring device, and a calibration device. The probe includes a sensor which detects an electric field and outputs signals representing the detected electric field. The measuring device measures static electricity on the basis of the signals output from the sensor. The calibration device generates a reference electric field. The measuring device is adjusted when the sensor detects the reference electric field produced by the calibration device.

A brain function examining apparatus and others for performing an examination of a brain function by detecting a pupillary size of a subject's pupil are provided. The brain function examining apparatus includes a light source for illuminating the pupil, a pupillary detector for detecting the pupillary size, an index calculator for calculating, based on the pupillary size detected by the pupillary detector, a subject index indicative of a characteristic of the pupil, a database for storing a base index indicative of a characteristic of the pupil that can be used as reference, and an output unit for outputting the subject index, calculated by the index calculator, and the base index stored in the database.

A silent-chain transmission apparatus includes a silent chain and a sprocket. The silent chain is formed of a plurality of plates, each of which has a pair of link teeth each having an inner crotch and an outer flank. The plates are connected through use of connection pins. The sprocket has sprocket teeth that come into meshing engagement with the link teeth of the silent chain. Each of the inner crotches has a projection that is formed on a tooth tip side with respect to a working pitch line and has a straightly profiled portion.

In a transmission comprising an endless silent chain and a sprocket the inside tooth faces of the link plates of the chain are identical to tooth profiles, arranged axially, of a hob cutter for forming teeth of the sprocket. The inside and outside tooth faces also satisfy Hi=Ho+Hs, where Hi is the distance from a pin center line Lp to a pitch line Li of the inside tooth faces, Ho is a distance from the pin center line to a pitch line Lo of the outside tooth faces, and Hs is the amplitude of polygonal motion of the chain. Each link plate also has a concave bottom surface between its teeth to avoid interference with edges of the involute teeth arising due to the chain polygonal motion amplitude when the outside tooth faces are brought into meshing engagement with the involute teeth and become seated thereon.

A silent chain drive mechanism includes a silent chain for transmitting power between a larger sprocket and a smaller sprocket, wherein the inside flanks of one link plate of the silent chain are profiled to project outward of the outside flanks of the adjacent link plates, and tooth flank configurations of the larger and smaller sprockets are formed by involute curves arranged to satisfy the expression A1>Ac≧A2, where A1 is a pressure angle of the smaller sprocket, A2 is a pressure angle of the larger sprocket, and Ac is a pressure angle of the inside flanks of teeth of the link plates. With this arrangement, the chordal action of the silent chain is suppressed at both the larger sprocket side and the smaller sprocket side, thereby reducing vibrations and noises accompanied with the chordal action and improving the driving performance and durability.

A spring-actuated electromagnetic brake includes an adjustment plate attached a rotating shaft and having an annular recess in one end face thereof facing a boss of a brake plate slidably mounted on the rotating plate. An annular elastic member is disposed in the annular recess in such a manner that when the brake is in the released state, the elastic member partially projects from the recess and is in contact with an end face of the boss. A slide-distance adjustment bolt having an enlarged head and a thread-free shank of a length larger than the thickness of the adjustment plate extends through an opening of the adjustment plate and is threaded on the end face of the boss. The brake plate is slidable in one direction by the force of the brake spring and in the opposite direction by the recovery force of the elastic member. The range of sliding movement of the brake plate is determined by the difference between the length of the shank of the bolt and the thickness of the adjustment plate. The gap provided between the armature and the lining when the brake is in the released state is smaller than the gap provided between the field and the armature when the brake is in the engaged state, so that a striking noise generated when the armature strikes against the lining by the force of brake springs is reduced correspondingly.

A transfer guide for a high-speed power transmission, which can cancel a change in a transmission chain speed so that smooth transmission timing can be realized and a driving power and vibration noises of the transmission chain can be significantly reduced. A curve track T for a transfer guide 100 for a high-speed power transmission disposed in a transfer position X2 just before a transmission chain, which is traveled at a fixed speed by pressing the chain on the inner circumferential side of the chain with a travel limiting guide R, is meshed with a sprocket S, is defined along an movement passage of the roller C2 in the transfer position X2. Thus, the change in the transmission chain speed is canceled so that smooth transmission timing can be reliably realized and the driving power and vibration noise of the transmission chain can be significantly reduced.

An apparatus for examining a subject's brain functions acquires two or more indexes of pupillary indexes that show the subject's pupillary characteristics, visual indexes that show the subject's visual system functions, intelligence evaluating indexes that are results of the an intelligence test carried out on the subject, and behavior evaluating indexes that show the results the subject's behavior examination. Two or more indexes are stored in a memory and outputted from an output unit. By combining two or more kinds of independent indexes, accurate determination of dementia cases and further the degree of senescence of brain functions can be achieved. In addition, the brain function examining apparatus puts together a number of a plurality of indexes by the multivariate calculation and converts the indexes into different values of fewer numbers.

A routeless guiding method for guiding a moving body, in which the driving speeds of the body's right and left driving wheels are independently controlled according to an operational expression including parameters based on a positional relation between the body's present position and a target position to guide the body to a target position without designating a route. To guide the body, the gain of an azimuth deviation parameter related to a traveling direction of the moving body to the target position is changed in response to the distance between the moving body and the target position, and further the gain is made to be of two kinds so that the traveling route of the moving body is not unstable in shifting from one gain to another.
