Abstract: PROBLEM TO BE SOLVED: To improve the monitoring of traffic distribution information by dynamically connecting a system to one of plural antennas, which is the most suitable for the transmission/reception of an RF signal, and periodically monitoring, storing and displaying information showing the use of the respective antennas. SOLUTION: A micro controller 267 stores traffic distribution information in a memory 300 in response to that the transmission detection signals from respective transmission switches exist on a line 315. The micro controller 267 stores information showing a specified radio channel device where the transmission detection signal exists and the corresponding antenna having the maximum reception signal intensity of the RF signal with a specified operation frequency in the memory 300. The information is updated by periodical frequency. The memory 300 stores traffic distribution information associated with the three radio channel devices and can set up it as the matrix of information containing the size of the matrix corresponding to the number of the radio channel devices in a control group and the number of the antennas on a base side.

Title: Base oil and composition for metal lubrication
Inventor: KAWAKATSU KUNIO
IPC: C10M107/32
Filed: 1980-06-26
Abstract: PURPOSE: The base oil for metal lubrication having its heat resistance improved by having oxyalkylene ether of bisphenols contained in the lubrication base oil.  
     CONSTITUTION: The oxyalkylene ether of bisphenols is contained in the base oil for metal lubrication and, preferably, 20wt% or more oxyalkylene ether of bisphenols as the base oil is contained in the composition. It is preferable that the oxyalkylene ether of bisphenols to be used has a larger molecular weight in terms of lubricating properties, low flammability and low toxicity, but too large a molecular weight results in a bad heat resistance. Therefore, the oxyalkylene ether having an average molecular weight of 400W2,000 is usually used. Since the oxyalkylene ether is easy to handle if it is liquid at a normal temperature, it is preferable to use propylene oxide alone or together with ethylene oxide. It is preferable to use bisphenol A and bisphenol B as bisphenols.

Abstract: PURPOSE:To improve the connection end factor to a mobile equipment by calling this mobile equipment as long as the coincidence is obtained between the position information and the charging index decided by an area designating code even though no coincidence is obtained between the area designating code sent from a calling subscriber and the position information of the mobile equipment to be called. CONSTITUTION:A central control equipment 7 collates a transmitted area designating code (m=51) with the position information (n=54) on a mobile equipment 31 to be called and registered within a memory area 21 and starts a charging index collation part 71 when no coincidence is obtained from said collation. The part 71 refers to a memory area 22 and extracts the position information having the same charging index as the code (m=51) in response to the local oscillation code sent from a station of a calling subscriber 6. Then the part 71 replaces the code (m=51) sent from the subscriber 6 with the information (n=54) after detecting that the information (n=54) registered in the area 21 is coincident with the information (n=54) extracted from the area 22. Then the general calling is given to the equipment 31 via a radio base station set in an area 44 where the equipment 31 exists.

Abstract: PROBLEM TO BE SOLVED: To reduce cost by unitizing an arm supported by a bracket and a torsion bar integrally connected in the tortional direction at one end thereof, at the other end of a bar member whose one end is fixed to the bracket at nearly right angles against the movable face of the arm. SOLUTION: When a movable frame (b) of a sliding door is supported by a hinge (c) to a fixed frame (a) of a roof floor, a rail is laid on the inside face of the side frame of the movable frame (b) and a torsion bar unit 1 is fixed to the fixed frame (a) by a bracket 2. Then, a roller 15 pivotted at the tip of the arm 8 is fitted to the rail 16 and the movable frame (b) is brought to a state diagonally opened by the restoring force of the torsion bar 11 in a state that a wire for closing the window has been let out. In this time, the movable frame (b) is closely stuck to the fixed frame (a) while dragging in the wire for closing the window to close the window and accumulate a restoring force by largely twisting the bar 11 and also open the window by letting out the wire for closing the window. In this way, it is not necessary to needlessly increase the tortional rigidity.  The unit is made light in the weight and low in the cost and the fitting work can be carried out in a short time by only fitting the bracket 2 to the window frame.

Title: Driving method of polyphase rotating field motor
Inventor: WATANABE AKITO
IPC: H02P27/08
Filed: 1995-03-22
Abstract: PURPOSE: To reduce electromagnetic interference in a polyphase rotating field motor driven in a PWM method. CONSTITUTION: An arithmetic controlling circuit 1 calculates a driving current (Io) on the basis of a torque command (N). A rotational phase of a motor 5 is detected by an encoder 6 and the result is fed to the arithmetic controlling circuit. Each phase factor according to the rotating phase of the motor 5 is searched, and the polarity of pulses and the pulse width are determined according to these factors. The pulses are arranged in a way that the leading edge and trailing edge of pulses overlap each other through the arithmetic control circuit 1 and the output is fed to each phase driving unit 2, 3 or 4. As a result, cross-talk noises caused by PWM driving signals are canceled mutually, and thereby electromagnetic interference can be reduced.
