A robot is provided with a multi-joint robot arm, an external force detection unit that is installed in the arm, and detects an external force, a joint movable-state calculation unit that calculates a movable state of a joint of the arm, an external force conversion unit which, based on the movable state calculated by the joint movable-state calculation unit, converts the external force detected by the external force detection unit to a converted external force, and a control unit that controls the arm based on the converted external force so as to regulate the operation of the arm.

A digital camera which can change gradation properties comprises a CCD image pickup element 105 for photographing a subject, an exposure control mechanism 103 for controlling an exposure on the image pickup element 105, a digital processing circuit 108 including a gradation converting circuit for being capable of generating image signals having different gradation properties (gamma properties) based on the output signal from the image pickup element 105, and a system controller 112 including a selecting circuit for selecting one of the different gradation properties, which is used in the gradation converting circuit. In the digital camera, to suppress the change of a sensitivity (output level) due to the a change of the gradation property, the exposure control mechanism 103 changes a control target value to control the exposure in accordance with the selected gamma value so that the output level is maintained at constant in the average exposure.

The encoding apparatus generates information for generating a high quality high frequency sub-band signal when expanding the frequency band at the decoding apparatus. A signal encoding apparatus divides an input time series signal into a plurality of sub-bands and encodes a low frequency sub-band signal to generate encoded data of the low frequency sub-band signal. Concurrently, it compares the frequency amplitude peak of the new high frequency sub-band signal generated from the low frequency sub-band signal and the original high frequency sub-band signal and generates frequency amplitude peak information of the high frequency sub-band signal. Similarly, it compares the gain of the new high frequency sub-band signal generated by using the low frequency sub-band signal and the original high frequency sub-band signal and generates gain information of the high frequency sub-band signal. Subsequently, the signal encoding apparatus multiplexes the encoded data of the low frequency sub-band signal, the frequency amplitude peak information of the high frequency sub-band signal and the gain information of the high frequency sub-band signal and outputs compressed data.

A sheet feeder includes: a feeding roller for feeding a sheet; a press member for pressing the sheet against the feeding roller; and a double feed detector for detecting double feed of the sheets when the sheets are fed in superimposition; wherein the feeding roller and the press member are opposed each other at a sheet holding portion for holding the sheet to be fed therebetween, and the double feed detector is placed to be able to detect double feed of the sheets in a region being adjacent to the sheet holding portion, an amplitude of the sheet being suppressed in the region.

A fuel gas heating control equipment in accordance with the present invention is provided with a gain-determining portion 21 and a time-constant-determining portion 22 which determine values of a gain and a time constant to be used for PI calculations being performed by a PI calculation portion 14. The gain-determining portion 21 specifies a small time constant for the PI calculation portion 14 during load fluctuations when the generator output increases, and specifies a large time constant for the PI calculation portion 14 when the generator output reaches the maximum output. In consequence, during load fluctuations, responsiveness is good and a rapid change in temperature can be followed, so that a fuel gas temperature will not fluctuate in response to a slight change in temperature at the maximum output, thereby achieving a stable fuel gas temperature.

A substrate processing method uses a substrate processing apparatus including a chamber for accommodating a substrate, a lower electrode to mount the substrate, a first RF power applying unit for applying an RF power for plasma generation into the chamber, and a second RF power applying unit for applying an RF power for bias to the lower electrode. The RF power for plasma generation is controlled to be intermittently changed by changing an output of the first RF power applying unit at a predetermined timing. If no plasma state or an afterglow state exists in the chamber by a control of the first RF power applying unit, an output of the second RF power applying unit is controlled to be in an OFF state or decreased below an output of the second RF power applying unit when the output of the first RF power applying unit is a set output.

An image pickup apparatus comprising an array of unit cells, vertical signal lines, and a control circuit. The unit cells are arranged in rows and columns. Each unit cell has a light-receiving device for receiving light and generating an electric charge corresponding to the light, a charge-accumulating section for accumulating the electric charge generated by the light-receiving device, a transfer device for transferring the electric charge from the light-receiving device to the charge-accumulating section, and a charge-limiting device for limiting the electric charge accumulated in the charge-accumulating section. The vertical signal lines extend along the columns of unit cells, respectively, each for receiving a electric data item corresponding to the electric charge accumulated in the charge-accumulating section of any unit cell of the associated column. The control circuit controls each of the unit cells, causing the charge-limiting device to limit the charge generated by the light-receiving device during a first period and transferred to the charge-accumulating section through the transfer device. The charge generated by the light-receiving device during a second period following the first period and transferred to the charge-accumulating section through the transfer device is added to the electric charge accumulated in the charge-accumulating section.

Embedded check-valve assembly (100, 600) for integration in a micro-fluidic system. The assembly can include a check-valve chamber (104, 604), an inlet port (106, 606) and an outlet port (108, 608) formed from at least one layer of liquid crystal polymer (LCP) film to form a substrate (102, 602). A plug (114, 614) is disposed within the check-valve chamber.
