An anti-shake system includes a movable portion to which an optical element is mounted; a support member which holds the movable portion in a manner to allow the movable portion to move freely in directions orthogonal to an optical axis; and a drive system which drives the movable portion in the directions orthogonal to the optical axis. A natural frequency of the movable portion that originates from the movable portion and the support member is set within the range of frequencies of shaking of an apparatus equipped with the anti-shake system which is caused by hand shake.

A plasma jet spark plug provides improved ignitability and durability by forming a part of a spark discharge gap outside the electric discharge space which generates plasma. An ignition system for the plasma jet spark plug is also disclosed. The plasma jet spark plug includes a center electrode, an insulator defining an axial bore which partially surrounds the center electrode, a cavity surrounded by an inner circumferential face of the axial bore which extends from an opening portion of a front end of the axial bore of the insulator and wherein a front end face of the center electrode is formed. A ground electrode is bent towards a front end portion of the insulator.

An olfactory method for simultaneously assessing a quantity and a quality of odors in an airstream, comprising the steps of determining a first mean value of results of ratings of an acceptability of an odor of a single airstream, rated by a group of test persons; determining a second mean value of results of ratings of an odour intensity done by the same group of test persons for the same odorous airstream; determining a decipol value of ratings of a perceived air quality according to the method of Fanger of the same odorous airstream, rated by the same group of test persons; providing a matrix containing all mathematically possible values of the acceptability of rating, the odor intensity rating and the decipol values of the perceived air quality, wherein each value or a range of values of one the three rating categories is assigned to one score in a scale of scores: determining a score for each of the values taken from steps a), b), and c) by classifying it into one of the values or ranges of values in a corresponding category in the matrix of step d), which results in three scores; and calculating a third mean value of the three scores, resulting in an overall average score corresponding to an overall quantitative and qualitative odor characteristics of the airstream evaluated.

Provided is a colpitts quadrature voltage controlled oscillator capable of obtaining quadrature orthogonal signals using a quadrature combination between a base and a collector of each transistor, without using an additional circuit such as a coupled transistor, a coupled transformer, a multiphase RC filter, etc. Accordingly, since nonlinearity, increased phase noise, a decrease in the Q-factor of an LC resonator, and increased power consumption can be avoided, a colpitts quadrature voltage controlled oscillator that has low phase noise, low electric power consumption, and a compact size can be implemented.

Along a rotational direction of a photoreceptor, a cleaner unit for cleaning a surface of the photoreceptor, a lubricant applying apparatus for applying a lubricant to the surface of the photoreceptor, and a charging device for charging the surface of the photoreceptor are disposed in this order. Further, the lubricant applying apparatus applies the lubricant to the surface of the photoreceptor which has been cleaned and has not been charged. As a result, it is possible to uniformly apply the lubricant to the surface of the image carrier for an extended period of time with stability.

A robot vision system for outputting a disparity map includes a stereo camera for receiving left and right images and outputting a disparity map between the two images; an encoder for encoding either the left image or the right image into a motion compensation-based video bit-stream; and a decoder for extracting an encoding type of an image block, a motion vector, and a DCT coefficient from the video bit-stream. Further, the system includes a person detector for detecting and labeling person blocks in the image using the disparity map between the left image and the right image, the block encoding type, and the motion vector, and detecting a distance from the labeled person to the camera; and an obstacle detector for detecting a closer obstacle than the person using the block encoding type, the motion vector, and the DCT coefficient extracted from the video bit-stream, and the disparity map.
