摘要:
An aluminum oxide sintered body contains aluminum oxide in an amount of not less than 99% by weight and at least one selected from magnesium oxide, calcium oxide and silicon oxide, and contains phosphorus of not more than 0.0025 parts by weight to 100 parts by weight of the aluminum oxide sintered body. This avoids that phosphorous exerts adverse effect on the sintering properties of an aluminum oxide sintered body, especially the sintering properties of a large aluminum oxide sintered body, causing the sintered body to lack uniformity between the sintered body inner portions and outer portions. Therefore, this aluminum oxide sintered body is suitably used in semiconductor manufacturing apparatus members or liquid crystal manufacturing apparatus members.

An electronic camera having a continuous shooting function includes a resolution conversion unit capable of performing resolution conversion at least at a high resolution and at a low resolution that is lower than the high resolution, an image compression unit capable of performing image compression at least at a low compression factor and at a high compression factor that is higher than the low compression factor, and when a continuous shooting unit executes continuous shooting, the image compression unit performs image compression at a high compression factor if the resolution at the resolution conversion unit is set to a low resolution.

A thickness-determining apparatus for determining a wall thickness of a microcapsule having a refractive index n1 comprises a sensor 1 for detecting a light scattering intensity data I1 with respect to the microcapsule dispersed in a medium having a refractive index n1, and a light scattering intensity data I2 with respect to the microcapsule dispersed in a medium having a refractive index n2; a memory circuit 3 for storing a theoretical equation correlating a light scattering intensity characteristic with a particle size; and an arithmetic circuit 5 for calculating an inner diameter r1 and an outer diameter r2 from the theoretical equation based on the light scattering intensity data I1 and I2, and calculating the wall thickness.

A steering wheel lock apparatus having high reliability. The steering wheel lock apparatus (1) includes a lock pin (21), which engages a steering wheel (5), a motor (23), which moves the lock pin, and a control circuit (31), which controls the motor. The control circuit includes a power supply line (72b), which provides locking current to the motor for locking the steering wheel. A breaker circuit (61) selectively breaks the power supply line when a user operates an ignition switch knob (81) to start the vehicle.
摘要:
A system that directly monitors a physical condition of a driver. The system includes a portable device carried by the driver. The portable device includes a perspiration sensor, for detecting biological information serving as an index representing the physical condition of the driver, and a transmitter circuit, for generating a transmission signal including the biological information detected by the perspiration sensor. The monitoring device, which is installed in the vehicle, includes a receiver circuit for receiving the transmission signal from the portable device. A microcomputer and a display inform the driver of his or her physical condition based on the transmission signal received by the receiver circuit.

A module connector has a simple module base connector capable of being used instead of a module socket, thereby allowing connection to wiring members such as an inexpensive flexible flat cable. The module base connector, formed as a thin plate, is interposed between a plurality of terminals of a small-sized module and a wiring member. This base connector includes a fitting frame and a connector housing which are formed integrally. A module fitting part of the fitting frame is provided with a terminal pattern electrically connected to the plurality of terminals of the module housing. The connector housing is provided with connection terminal pieces each having an elastic contact portion connected at one end to the wiring member of a flexible flat board, and a press contact portion connected at the other end to the terminal pattern.
摘要:
The number of spreading codes multiplexed in a received signal is detected, and switches 4 and 5 are switched to the RAKE demodulation section 2 side if the detected number of spreading codes is less than a predetermined threshold value, and to the JD demodulation section 3 side if greater than or equal to the predetermined threshold value. As a result, joint detection demodulation is used only when the number of multiplexed spreading codes is large—that is, when the number of users is large—and consequently power can be saved during demodulation.

摘要:
A mobile station apparatus in a CDMA/TDD mobile communication system employs a communication frame including a plurality of time slots. The time slots include a plurality of forward link time slots, disposed at regular intervals in the communication frame and assigned a common control channel. The time slots further include time slots other than the plurality of forward link time slots, divided into reverse link time slots and forward link time slots according to an amount of information on a forward link and on a reverse link. The mobile station apparatus includes a receiver that receives the communication frame including the plurality of time slots. A measurer measures individual reception qualities of the plurality of forward link time slots in the received communication frame including the forward link time slots assigned the common control channel. A weighter assigns a weight to each measured reception quality of the plurality of forward time slots. A transmission power controller performs transmission power control for reverse link time slots according to individual reception qualities of weighted forward link time slots.
