In an audio signal transmission/reception device that receives and emits sounds so as to perform transmission and reception of audio signals via communications, user operability can be improved and the size of a main unit can be reduced. It is equipped with a speaker array for arranging a plurality of speaker units, which are arranged on the lower surface of the main unit, and a microphone array for arranging a plurality of microphones, which are arranged on the side surface of the main unit in its longitudinal direction. Legs having hollow structures are attached to the main unit so as to support the main unit at a prescribed height above the mount surface (e.g., the surface of a desk) and to secure good sound emission characteristics of the speaker array.

A radio communication apparatus includes antennas, transceiver units respectively connected to the antennas, and a radio control unit that controls the transceiver units, simultaneously inputs same transmission data to the transceiver units, and instructs, every switching cycle of frequency hopping, the transceiver units to start check processing for an idle state of frequency channels. The transceiver units respectively include hopping control units that switch the frequency channels every fixed time in synchronization with a communication partner and control such that each of the transceiver units uses a different frequency at the same hour. When determining that a frequency channel is in an idle state before a predetermined time elapses from the start of the check processing for an idle state, the transceiver units transmit the transmission data to the communication partner using the frequency channel.

In a knee protecting airbag device of the present invention, an airbag is folded and housed on the front side of the knees of a seated passenger. The airbag is protruded rearward of a vehicle from a protruding opening and expanded and inflated upward, when an inflating gas flows in. And, the airbag is arranged on the front side of the knees of the passenger between a member on the body side and the knees of the passenger thereby to protect the knees of the passenger. The protruding opening has a transverse width size set within a range of ⅛ to ⅔ of the transverse width size of the airbag having completed its expansion and inflation.

If a signal-to-noise ratio determining unit determines that a ratio of a signal level to a noise level exceeds a threshold, and also if a preamble determining unit determines that logical data matches preamble data, a communication apparatus starts receiving a communication frame. In other words, the communication apparatus starts receiving the communication frame only after confirming existence of a carrier.

In the knee protection airbag device of the present invention, an airbag folded and housed in a case opened rearward of the vehicle pushes open the door portion of an airbag cover assembled with the case, upon inflow of inflation gas from the inflator. Around the airbag cover, there is arranged an interior decoration member for vehicle which is provided separate from the airbag cover. The door portion includes at least an upper door openable upward. The upper door is formed in such a size as to cover a gap formed between the interior decoration member and the airbag cover when opened upon deployment of the airbag.

A memory includes a memory array and address conversion table. The memory array has a plurality of page memories addressed in accordance with a logical address on an address bus. The address conversion table converts the logical address assigned to the page memory into a physical address and outputs it to the page memory.

Even when the timing signal used in the internal circuit is formed from the clock signal by the delay device, a margin to the timing signal is deleted or reduced so that operating frequency is designed as high as possible. A delay device is composed of inverters which are connected in series and time constant circuits connected in parallel with the outputs of the inverters. The time constant circuits include series circuits each having an MOS transistor and a capacitor. The change of the on-state resistance of the MOS transistor is controlled by the voltage control signal of a voltage controlled oscillator. The delay time of the internal delay device is externally controlled so that the delay time of the delay device for generating the timing signal of an internal circuit is changed. The internal circuit can be operated in a normal manner even if the operating frequency is changed to lower than usual.

An alternate route to improved multimedia performance without replacing the central processor unit (CPU) is presented, through the utilization of general-purpose components available in a computer. The method relies on the use of integrated circuit memory boards having a data port for directly inputting encoded image signals from an I/O device into the memory. An on-board decoder provided on the IC memory is used to decode the variable-length encoded input signals. This approach enalbes to reduce the computational load on the CPU so that the usual bottleneck which is the slow process of data exchange between the CPU and the memory boards is eliminated. The CPU directly accesses the processed image data in the memory and displays the final image on the monitor. This route to increasing the image processing speed of a computer has considerable merits because it is low cost and is readily applicable to mass-produced IC memories with only a few additional fabrication steps.

A liquid oil and fat ingredient or others are carried by pores of a porous carrier composed of porous starch grain obtained by reacting an enzyme having raw starch digestive activity onto the starch. With starch being used as porous carrier, the powder preparation according to the present invention is not harmful to the human body, it can be supplied continuously in great volumes, manufactured cheaply without difficult processing, and moreover, being completely biodegradable, this powder preparation does not cause any environmental problems. It can be used in various industrial fields.
