Abstract: An expansion valve includes a valve main body having a valve chamber therein, a valve body arranged within the valve chamber, a valve body support member supporting the valve body, an urging member urging the valve body toward a valve seat, an actuating bar pressing the valve body in an opening direction of the valve against urging force generated by the urging member, and a vibration proof spring suppressing vibration of the valve body or the actuating bar. The actuating bar has an outer peripheral surface of which a part constitutes a contact surface slidably contacting with the vibration proof spring, and the contact surface has a shape by which the amount of deformation of the vibration proof spring becomes greater as the valve body goes towards a closing direction of the valve.

Abstract: The invention provides an expansion valve which can suppress production of an abnormal noise from an expansion valve in a case where an opening degree of the expansion valve is very small. The expansion valve is provided with a valve main body which has a valve chamber, a valve body which is arranged within the valve chamber, a valve body support member which supports the valve body, an urging member which urges the valve body toward a valve seat, an actuating bar which presses the valve body in an opening direction of the valve, a vibration proof spring which suppresses a vibration of the valve body or the actuating bar, and a contact surface with which the vibration proof spring slidingly contacts.

Abstract: In an automix system of network type, one of control equipment and audio equipment transmits time information data to the network, and the other of the control equipment and the audio equipment receives the time information data to thereby synchronize times with each other between the control equipment and the audio equipment. The audio equipment obtains time information when an operation device is manipulated based on the time information data received from the network and provides an operation event with that time information as a time stamp. The operation event provided with the time stamp is transmitted from the audio equipment to the control equipment via the network. This enables the control equipment to record the operation event with no time lag between the audio equipment and the control equipment.

Abstract: Motion-compensated interframe-prediction can be realized by affine-transformation of suitably divided areas of an object image with a reduced amount of calculations and an improved coding efficiency.

Abstract: A face (skin color) area of a person is extracted with minimized error irrespective of different skin colors of the human races. A hue value calculating portion determines a hue value from an input image (RGB signal). A primary discriminating portion extracts pixels having hue value that lies in a specified range defined by limiting values outputted from a control portion. A pixel-counting portion counts the extracted pixels. The control portion selects a threshold value for extracting a face area according to the count of the extracted pixels and outputs the threshold value to a face-area extracting portion which in turn extracts a face area according to the threshold value.

Abstract: An air-fuel ratio control system of an automotive internal combustion engine comprises a surge detecting device for detecting the surge level of the engine under a lean combustion operation; a lean combustion limit detecting device which issues a first signal when the detected surge level exceeds a given allowable limit and a second signal when the detected surge level fails to exceed the given allowable limit; and an air-fuel mixture diluting device which, when the leans combustion limit detecting device issues the second signal, dilutes the air-fuel mixture in such a manner that a surge level of the engine given by the diluted air-fuel mixture closely approaches the given allowable limit.
