Disclosed is a driving device capable of stably operating a plurality of actuators.Control units supply driving signals to piezoelectric elements to control actuators such that the actuators repeatedly change their operational states between a driving state and a stop state. In addition, the control units control the actuators to enter the stop state at different timings. As such, since the actuators enter the stop state at different timings, it is possible to reduce or prevent the situation that all of the actuators stop at the same time by shifting the use timing of a power supply circuit. In addition, it is possible to reduce or prevent the situation that all of the actuators are driven at the same time and a current is supplied to all the actuators at the same time.

A pet gate is disclosed. The pet gate having a front panel with a side panel disposed at each side of the front panel. Each side panel of the pet gate extends in a direction of intersection with the front panel allowing the pet gate to stand alone. The pet gate further comprises a door formed by one of the side panels in its entirety. The door is coupled on one side to the front panel by a hinge that allows rotation. The other side of the door is not coupled to a structural element. This allows the door to swing about the hinge in such a way that when in a state of use, the door opens and closes to allow passage of persons. The gate is set to a height such that it is difficult for a person to step over the gate.

A method for treating the surface of an object to be treated includes introducing a surface treatment fluid into a reaction vessel (4) capable of receiving an object, introducing-the surface treatment fluid into a separation vessel (14) after the object is subjected to surface treatment, and circulating the surface treatment fluid, from which a contaminant has already been removed, to the reaction vessel (4).At the time of treatment on the surface of the object, a circulation passage for the surface treatment fluid including the reaction vessel (4) is communicated and the surface treatment fluid is constantly circulated through the circulation passage.

A driving control device 20 controls supply of driving pulses to expand and contract a piezoelectric element 12 so that an expansion rate is different from a contraction rate, to vibrate a driving rod 17 and move a lens 21 frictionally engaging with the driving rod 17 in two directions. The driving control device 20 includes an actual driving pulse number measuring unit 32 that measures actual driving pulse numbers, which are required to move the lens 21 by a predetermined movement amount in the two directions, before a focusing operation of the lens 21, a correction factor calculating unit 33 that calculates correction factors relating to a driving pulse number, based on the actual driving pulse numbers and a predetermined reference pulse number; and a driving pulse number correcting unit 34 that corrects a driving pulse number supplied to the piezoelectric element 12 based on the correction factors.

To provide an anodic oxidation method, a titanium oxide film manufacturing method and a catalyst carrying method which is suitable, for example, for anodic oxidation of aluminum, titanium and catalyst carrying on the surface of alumite (registered trademark), capable of generating an oxide film at a low cost and rapidly by eliminating the use of a strongly acid or strongly basic electrolytic solution and using a carbonated water as an electrolytic solution, capable of controlling the sealing treatment of oxide film through a simple method, capable of effecting the oxide film dyeing and catalyst carrying rationally and easily, and capable of effecting the catalyst carrying safely and surely without eroding a base material. An object (3) to be treated is electrolyzed in an electrolytic solution received in a treatment vessel (1) serving the object (3) as an anodic electrode. It is an anodic oxidation method in which an oxide film is generated on the surface of the object (3). A carbonated water of a predetermined acid concentration generated by dissolving a pressurized carbon dioxide in a predetermined quantity of water (7) is used as the electrolytic solution.

An error correction encoding method and apparatus, and an error correction decoding method and apparatus are provided without requiring transmission of tail bits. A turbo encoding step (ST41-ST45) and a transmission termination processing step (ST46→ST44-ST47) are included. In the turbo encoding step, a transmission information bit sequence is divided into a plurality of frames. Registers in each recursive systematic convolutional encoder are initialized before turbo encoding of a first frame. After turbo encoding of the first frame is carried out, a second frame and following frames are continuously subjected to turbo encoding without initializing the registers in each recursive systematic convolutional encoder before the turbo encoding of the second frame and following frames. In a transmission termination processing step, tail bits for initializing the registers in each recursive systematic convolutional encoder are calculated only after a final frame has been subjected to turbo encoding.

The present invention relates to an apparatus, such as a digital camera, in which a battery is removably loaded and a memory card is detachably inserted so that the apparatus is supplied with power from the battery and performs processing including writing data on the memory card. The invention ensures that data write inhibit operation on the memory card is performed before the memory card is removed. A memory card slot for inserting the memory card is provided inside a battery lid to be accessible by opening the battery lid. A circuit detects separation of a battery contact plate from the battery due to opening of the battery lid and turns the memory card to a write protect state.
摘要:
In a rangefinder, if sensor data initially received by a sensor data storage part from an A/D converter includes data with low contrast, the sensor data storage part receives the sensor data at least one additional time, adds additionally received sensor data to the initially received sensor data, and stores their sum. In accordance with the sum of sensor data stored in the sensor data storage part, a correlation calculation and a rangefinding calculation are carried out, which enables rangefinding with respect to an object having low contrast. Also, the time required for A/D-converting the sensor data again and adding the resulting data to those initially obtained is much shorter than the integration time required for integrating output signals of a pair of line sensors a second time for a region with low luminance and low contrast.
