摘要:
The service life of memory cards is to be substantially elongated against the occurrence of faulty blocks. A control logic searches blocks in a nonvolatile memory cell array for any acquired fault on the basis of a fault-inviting code in a management information section. If any faulty block is detected, the faulty block will be subjected to write/read comparison of data to judge whether or not the data in the block are normal. Any block determined to be normal will undergo rewriting of its fault-inviting code and registered as a normal block. Further, the registered block is stored into a write management table in the management area as a writable block. This enables an essentially normal block judged faulty on account of an erratic error or some other reason to be restored.

The invention intends to provide a memory card conforming to an HS-MMC mode in a standard of a multimedia card, while securing compatibility of both standards of the multimedia card and an SD card. In a normal MMC mode, the data is outputted at a fall edge of a clock signal. A frequency of the clock signal is about 20 MHz. When the data is outputted at the fall edge of the clock signal, data output is in time for a next clock signal. When a parameter ‘1’ is set to a timing register provided in a host interface, the memory card is transitioned into the HS-MMC mode. In the HS-MMC mode, a clock signal frequency is increased to about 52 MHz. Here, the data is outputted at the rise edge of the clock signal, whereby the data output is brought in time for the rise edge of the next clock signal.

The present invention is directed to suppress data loss caused by power shut-down during a rewriting process and to shorten time required to make a depletion check.A nonvolatile memory apparatus includes a rewritable nonvolatile memory and a card controller. The nonvolatile memory has a physical address area corresponding to a logical address and a save area. In response to a data rewrite instruction on a required logical address, the card controller stores data in a predetermined physical address area corresponding to the logical address to the save area and rewrites the data stored in the physical address area. When rewriting of the physical address area is incomplete, the card controller rewrites the data in the physical address area with the data stored in the save area. Thus, data loss caused by the power shut-down can be suppressed by data backup, and it is sufficient to make the depletion check in two places of the save area and the physical address area.

A technique which in a portable or laptop ultrasonic diagnosis apparatus, optimizes the position of a hinge mechanism for connecting a display section having a touch panel and a main body and the strength of the main body and also reduce the influence of noise between mutual sections, such as an ultrasonic image processing circuit board, a power source, a CPU board and the like, which are arranged inside the main body is disclosed. According to this technique, on a bottom surface of a bottom case 11 in the main body, a supporting section 12 for supporting a display section 20 is formed to stand upright and extend in a width direction, at a position that is dislocated to a front end F side from a rear end R of a main body 10. Also, a region A in which the ultrasonic image processing circuit board is arranged and regions B, C in which a power source unit and the CPU board are arranged, respectively, are partitioned by means of the supporting section 12.

In a steering apparatus, an upper bracket that supports a steering column is configured as a breakaway bracket, and has a telescopic adjustment function that allows the steering wheel position to be adjusted in the axial direction of the steering column. The upper bracket has a first through-hole extending through the upper bracket in the axial direction. The upper bracket is provided with a guide rail 7 that has a fixed portion and a body portion. The fixed portion is fixed to a mounting stay. The body portion extends from the fixed portion toward the front of a vehicle in the axial direction, and is inserted in the first through-hole.

An ultrasonic diagnostic apparatus includes: a plurality of vibration elements (1) that transmit and receive an ultrasonic beam; a plurality of transmission circuits (2) that are connected to the respective vibration elements and output a transmission driving signal to be used for driving the vibration elements; and a transmission power source (3) that supplies electric power to the transmission circuits. The ultrasonic diagnostic apparatus further includes: a pulse detection unit (21) that detects a transmission signal to be used for generating the transmission driving signal; an electric power measurement unit (20) that detects an amount of electric power supplied to the transmission circuits as a whole; a distribution calculation unit (24) that calculates an amount of electric power distributed into each of the vibration elements based on outputs of the pulse detection unit and the electric power measurement unit; and a power distribution derivation unit (22) that derives electric power having been supplied to each of the plurality of vibration elements based on an output of the distribution calculation unit, wherein the transmission driving signal is controlled based on the power distribution derived in the power distribution derivation unit. With this configuration, it is possible to provide a more compact and highly reliable ultrasonic diagnostic apparatus capable of performing a temperature monitoring that detects local heat generation of the vibration elements based on the actual transmission power by using a circuit with a reduced number of components.
