摘要:
From a transmitter (18) and a transmission antenna (10), a first frequency signal having a fixed frequency is transmitted for a predetermined time or more, a second frequency signal having a certain frequency difference from the first frequency signal is transmitted for a predetermined time or more, and a third frequency signal having a frequency difference twice the frequency distance from the first frequency signal is transmitted for a predetermined time or more. Reflected waves from objects under measurement at the respective transmission frequencies are supplied to a reception antenna (11), a mixer (12), an analog circuit unit (13), an A/D converter (14), an FFT (15) and a signal processing unit (16). Then, the Doppler frequencies are measured for the reflected waves, objects under measurement are separated and detected at each Doppler frequency, and objects under measurements having the same Doppler frequency are separated to identify a plurality of objects under measurement from phase information and amplitude information of received signals acquired at each transmission frequency. In this manner, when there are a plurality of objects under measurement which are substantially equal in relative speed, these can be separated from each other and detected.

A neutral titanium dioxide colloid sol having a high stability in a neutral range and capable of forming a colorless transparent coating even when dried at room temperature is produced by mixing an acid titanium dioxide sol comprising 50 to 100 parts by weight of titanium dioxide colloidal particles and 5 to 50 parts by weight of a chelating agent for titanium ions with 1 to 50 parts by weight of an alkaline substance comprising at least one of alkali metal compounds and amine compounds, and optionally by adjusting the pH value of the liquid mixture to 5 to 10, or adjusting the pH value of the liquid mixture to 6 to 10, and then applying a deionization treatment to the mixture to thereby charge the titanium dioxide colloidal particles with negative electricity.
摘要:
Aluminum or aluminum alloy sheet is treated with an aqueous composition containing: (a) acrylic polymers or copolymers with a glass transition temperature of no greater than 0.degree. C., and (b) a water soluble zirconium compound, and dried. Preferably, the drying process is at an elevated temperature without intermediate rinsing. The coated aluminum/alloy surfaces exhibit corrosion resistance and paint adherence through a forming operation.
摘要:
To substantially prevent vibrations from arising due to a torque fluctuation of an internal combustion engine, a torque fluctuation of the internal combustion engine is detected, and a torque to be absorbed or generated by a motor generator is controlled so as to decrease the fluctuation torque according to a fluctuation torque information of at least one previous engine cycle.

摘要:
A torque control unit rotates a motor machine having a motor element and a load element. The load element is coupled to the motor element via a rotational main shaft and driven to rotate by the motor element. Rotational acceleration at each rotation angle during one revolution of the rotational main shaft is detected and fed back. An electromagnetic torque of the motor element is controlled so that a difference between the electromagnetic torque of the motor element and a load torque of the load element may become zero at each rotation angle of the rotational main shaft.

A television (1) including a function of a call using Internet Protocol (IP) includes: a communicating section to transmit and receive a call signal over an IP communication network; an incoming call destination identifying section (11) to identify a user who is designated as an incoming call destination; a judging section to detect a person who is present around the television (1); and a communication control section (13) to transfer the call signal to a mobile phone (4) of the user in a case where a plurality of persons containing the user has been detected. This offers a television capable of a call and ensuring the privacy of the call.
