An image pickup apparatus such as a video camera has the capability of automatic white balance control whereby the white balance is quickly adjusted for any object even just after an operator has turned on a power supply. An image pickup element converts an optical image of an object into an electrical image signal. The image signal is applied to a signal processing circuit and separated into a luminance signal and color signals. The separated color signals or the R and B signals are amplified by gain control circuits under the control of the correction signals supplied by a correction signal computing part, and then applied to a color-difference signal forming circuit which in turn produces color-difference signals (R-Y) and (B-Y). An encoder circuit generates a television signal in the standard form from the above color-difference signals and the luminance signal. In this processing, the white balance is adjusted according to a white balance control signal generated on the basis of information about a state of illuminance onto an object picked up last time and stored in a data storing part.

A method for predicting an effectiveness of chemotherapy is described. The method comprises a comparing step and a predicting step. The comparing step is a step of comparing a threshold value with a parameter of a cyclin dependent kinase (CDK) included in a sample containing a tumor cell obtained from a human patient. The predicting step is a step of predicting the effectiveness based on a comparison result of said comparing step. Above stated parameter is selected from the group consisting of an activity, an expression level, and a ratio of activity to expression level.

A camera for use with a flash apparatus is capable of achieving excellent color balance when a picture is taken using the flash apparatus. The camera comprises a flash control circuit that controls the amount of light generated by the flash apparatus, and a color adjusting circuit including a linear matrix circuit and a gain control circuit that controls hues or color saturation. A color correcting circuit controls the color adjusting circuit such that the hue or color saturation is properly adjusted in accordance with the amount of light determined by the flash control circuit.

A reciprocating linear actuator capable of reciprocatingly driving a plurality of movable elements (2 and 2) by a single stator (1). The movable elements (2 and 2) are connected to each other through a connection body (3) having a spring characteristic to be capable of displacement in the reciprocating direction of the movable element. The connection body (3) has such a shape that can be drawn with a single stroke on a two dimensional plane, and at least both ends thereof are connected to the movable elements (2 and 2), respectively. Since the connection body (3) is made of a flat spring, it requires less space for installation as compared to a connection body formed of a coiled spring. Further, since the entire connection body has an effective spring characteristic, a relatively smaller size is required for the connection body to provide a required spring characteristic. The less installation space for the connection body (3) is advantageous to a reduction in size of the linear actuator.

A system and method for performing hydrothermal treatment includes a scraper formed as a hollow cylinder. The scraper is positioned in the reactor vessel with the scraper axis substantially co-linear with the longitudinal axis of the cylindrical reactor vessel. A mechanism is provided to rotate the scraper about the longitudinal axis of the reactor vessel. One or more elongated scraper bars are positioned inside the reactor vessel between the scraper and the longitudinal axis of the reactor vessel. Each scraper bar may be held stationary with respect to the reactor vessel, or each scraper bar may rotated relative to an axis passing through the scraper bar to remove any solids that have accumulated on the scraper or on the scraper bar. To prevent accumulation of precipitating solids on the scraper bar itself, each scraper bar may have internal cooling channels or the capability of releasing a purging fluid.

A compact fluid control valve effects a reliable fluid flow regulation by the use of a shape memory alloy wire. The valve comprises a barrel provided with a base member and a valve body. The valve body is cooperative with the base member to define therebetween a valve opening in the course of an internal flow path through the valve for a fluid. The valve body is movable towards and away from the base member to vary the valve opening for regulating the flow of the fluid. A bias spring urges the valve body for varying the valve opening in one direction. The shape memory alloy wire connects the valve body to the barrel to move the valve body against the bias spring for varying the valve opening when heated. The barrel has anchor members for securing the ends of the wire. The anchor members are disposed on the exterior of the barrel and at such a portion that the wire stretches between the barrel and the valve body exteriorly of the barrel in an overlapping relation with a major portion of the barrel along the axial length thereof. Thus, the wire can be kept substantially away from the internal flow path of the fluid and consequently kept thermally unaffected thereby for a reliable flow regulation. Further, since the wire overlaps with the barrel, the entire valve can have a reduced axial dimension and be therefore made compact enough to be installed in a limited space.

In synthesizing a binary image signal with an inputted video signal, color pattern information is generated in synchronism with the inputted video signal, and the binary image signal is colored by using the color pattern information. It becomes possible to synthesize a variety of image patterns with a video signal by using a simple circuit arrangement.

The present invention relates to an apparatus to form a thin film on a specimen in a chamber by introducing electromagnetic waves into the chamber through a dielectric provided on a window of the chamber and activating the material gas in the chamber, and the forming apparatus according to the present invention has such a construction that an electrode connected to a high-frequency generating source is mounted near the dielectric. Consequently, when a high frequency is applied to the electrode, self-biases are generated on the inner surface of the dielectric (the surface on the side of the specimen), the plus ions in the chamber being attracted to the inner surface to strike thereon, and the sputtering being caused on the inner surface by the incidence energy. As a result, due to the sputtering effect, the generation of a pile of films on the inner surface of the dielectric can be prevented, while in the case where films are already piled on the inner surface of the dielectric these films can be removed.

An image reading device includes a background member, an illumination unit opposed to the background member, and a reader. The illumination unit emits light to a recording medium having an image thereon. The reader receives a reflection from the recording medium to read the image. The background member has a facing surface that faces the recording medium. The facing surface includes a reference portion on a center portion in a width direction of the background member. The reference portion has a higher reflectance than an end portion of the facing surface in the width direction.
