Abstract: A vehicle wheel information obtaining apparatus for obtaining wheel information relating to a wheel of a vehicle. The apparatus includes: (a) a wheel state detector which detects a state of the wheel; (b) a transmitter which is provided on the wheel and which transmits a wheel data set containing a wheel state data representing the detected state of the wheel and a wheel identification data identifying the wheel; (c) a receiver which is provided on a vehicle body and which receives the wheel data set transmitted by the transmitter; (d) a data processor which processes the wheel data set received by the receiver; and (e) a communication-intensity reducing device which reduces a transmission strength of the transmitter or/and a reception sensitivity of the receiver, such that the transmission strength or/and the reception sensitivity is lower when the data processor is in an identification-data registering mode, than when the data processor is in a wheel-state data obtaining mode.

Abstract: An internal memory section is divided into plural memory blocks. During a period of time, a relevant memory block of the internal memory section is connected to an external memory unit, while another memory block thereof is connected to a data holding section. During a succeeding period of time, the relevant memory block is connected to the data holding section, while the other memory block is connected to the external memory unit. Data exchange between the data holding section and the external memory unit via the internal memory section is performed while the alternative connection is repeated.

Abstract: A holder for a portable terminal allows the terminal to be used stably even if the terminal is mounted on a forearm, and prevents a heat from the portable terminal form being conducted directly. The holder for a portable terminal comprising a holding unit for holding the portable terminal detachably along the longitudinal direction of the forearm, a first mounting unit for fixing the holding unit to the forearm, and a second mounting unit for fixing the holding unit to a thumb or palm. The holding unit includes a forearm pad made of highly insulating material. The second mounting unit includes a palm band and a thumb band for fixing the holding unit to the palm and thumb, respectively.

Abstract: A holder allowing a portable terminal to be held selectively on a waist or thigh is provided. The holder for a portable terminal comprises an accommodating unit for accommodating the portable terminal, and plural wearing units for having the accommodating unit worn on a body. The plural wearing units include a thigh fixing band worn on the thigh, a belt fixing band suspended on a waist belt, and a waist belt band having only an inserting unit slightly wider than the width of the belt. The units are attached to the accommodating unit.

Abstract: A floating point multiply-add operating device in which a critical path in an addition process of continuous multiply-add operations of floating point numbers is shortened to improve operation efficiency is disclosed. This operating device includes: an exponent operating section for comparing an exponent of a floating point number of an operation result of a preceding multiply-add operation n with an exponent of a multiplication result of a subsequent multiply-add operation (n+1), and calculating an alignment shift count of the multiply-add operation (n+1) by the comparison result; and a mantissa operating section for aligning one mantissa of mantissas of two operands according to the alignment shift count inputted from the exponent operating section, calculating a sum of an aligned mantissa of the operand and the mantissa of the other operand, and normalizing a calculated addition result of the mantissas as needed, thereby calculating a mantissa of the multiply-add operation (n+1).

Abstract: A data processor has a general purpose register for storing arithmetic data and arithmetic results; an arithmetic device for MAC for performing a predetermined arithmetic operation by using the arithmetic data read from the general purpose register and outputting its arithmetic results to the general purpose register after a predetermined cycle; an arithmetic device for DIV for performing a predetermined arithmetic operation by using data read from the general purpose register and outputting its arithmetic results after a cycle longer than the predetermined cycle relative to the arithmetic device for MAC; and a temporary storing register for storing the arithmetic results outputted from the arithmetic device for DIV until the next arithmetic operation is terminated.

Abstract: An instruction sequence optimization apparatus optimizes programs used in an information processing system that includes a program memory for storing programs, and a processing unit for fetching the programs from the program memory via an instruction bus. The apparatus includes an instruction sequence analyzing unit for analyzing mutual dependence relations between respective instructions constituting the program, and an instruction sequence modifying unit for modifying sequences of the instructions insofar as the mutual dependence relations analyzed by the instruction sequence analyzing unit are not influenced, to thus reduce Hamming distances between bit sequences appearing on the instruction bus when the instructions are transferred from the program memory to the processing unit.

Abstract: Disclosed is a pipeline information processing circuit which comprises a register control unit for outputting a plurality of data held in registers at a time; an arithmetic operation unit for carrying out a collective arithmetic operation of a plurality of data; and a bypass control unit for comparing an operation result outputted from the arithmetic operation unit and a data outputted from the register control unit, selecting a data to be an object of the next arithmetic operation, and transferring the selected data to the arithmetic operation unit through a suitable bypass.

Abstract: A floating-point division cell consisting of partial remainder data register for storing parallel-partial-remainder data or third partial remainder data, divisor data register for storing parallel-divisor data or third divisor data, low-order divisor data generator for receiving the low-order portion of the divisor data and generating low-order divisor data, low-order partial remainder calculator for obtaining low-order multi-divisor data by multiplying the low-order divisor data and a multiple of 2 together and calculating new low-order partial remainder data by subtracting or adding the low-order multi-divisor data from/to the low-order portion of the partial remainder data, high-order divisor data generator for receiving the high-order portion of the divisor data and generating high-order divisor data, and high-order partial remainder calculator for obtaining high-order multi-divisor data by multiplying the high-order divisor data and a multiple of 2 together and calculating new high-order partial remainde

Abstract: A roller bearing lubricating device including a roller bearing for supporting a rotary shaft, a bearing housing for supporting the bearing, an oil tank provided in the housing for storing oil lubricating oil, a weir for forming an oil reservoir for dipping part of the bearing, and an oil supply passage for communicating between the tank and the reservoir with a part thereof having a predetermined minimum cross-sectional area.
