摘要:
In a head-up display device, when a preceding vehicle exists between a pre-movement information conveyor and a vehicle, the pre-movement information conveyor is moved to another position at which the pre-movement information conveyor is displayed as a recognizable post-movement information conveyor. Thus, the pre-movement information conveyor is removed from a state in which the pre-movement information conveyor is hidden behind the preceding vehicle, hence, becoming invisible. As a result, the incompatibility sense felt by the driver of the vehicle can be reduced and the information conveyor will be less overlooked.

A temperature sensor (33) detects the temperature of a MOS transistor (7), and a current detecting circuit (35) detects current flowing in the MOS transistor (7). When the voltage corresponding to the detected temperature or the voltage corresponding to the detected current is increased to a threshold value or more, an overheat state detecting signal and further switching signal is set to a high level. As a result, a switch circuit in a driving circuit (17) is turned on, and the gate resistance value becomes the parallel value of a resistor (25), and the PWM frequency in the PWM control circuit is lowered, whereby the switching loss of the MOS transistor (7) can be reduced under the state that the motor (2) is rotated.

A method for manufacturing a semiconductor using a wafer carrier, wherein the temperature of a wafer can be made uniform with few differences in surface composition distribution. A plurality of grooves are formed at the bottom of a wafer pocket of a wafer carrier, to make uniform the temperature of the wafer surface by diffusing heat. The grooves are deeper at the peripheral part of the wafer than at the central part, and groove density is higher at the peripheral part than at the central part. The groove patterns may include a plurality of wedge-shaped grooves widening from the central part toward the peripheral part, a plurality of circular grooves with narrowing interval therebetween from the central part toward the peripheral part, circular grooves with the diameter shortened from the central part toward the peripheral part, and square grooves with shortened sides from the central part toward the peripheral part.

Disclosed is an accumulator comprising a cylindrical shell including a cylindrical portion, a partitioning member for partitioning the interior of the shell into a hydraulic chamber and a gas chamber, and a port including a hydraulic fluid flow path for communicating the exterior of the shell and the hydraulic chamber. The variation of the pressure of a hydraulic fluid flowing into the hydraulic chamber is accommodated by expansion and compression of a gas in the gas chamber according to expansion and contraction of the partitioning member. The port is approximately airtightly inserted into the cylindrical portion of the shell, and is welded to an outer circumference of the cylindrical portion by means of welding.

A matrix-display panel such as a liquid crystal display panel is composed of row and column electrodes and liquid crystal interposed between both row and column electrodes. Pixels formed at each intersection of the electrodes are driven by imposing composite voltages consisting of scanning voltages supplied to the row electrodes and image data voltages supplied to the column electrodes. Pixels aligned along one row electrode are alternately connected to two or three neighboring row electrodes in a zigzag manner, and an interlaced scanning is performed by jumping one or two row electrodes at a time, thereby reducing a flicker frequency to an invisible level and making a line-scroll invisible. The pixels may be driven by switching a transistor connected to each pixel.

A groove shape and an inspection method capable of securely recognizing existence of a weld flaw of a single butt weld zone by a nondestructive inspection, such as a radiograph test or an ultrasonic test, are provided. A groove shape where a concave portion 5 is formed on a butt surface 1b and a butt surface 2b of pipes 1, 2 which are weldments to be welded is prepared and the weld zone welded by single butt welding is inspected by a nondestructive inspection such as a radiograph test or an ultrasonic test.
