Title: Transmission phase synchronizing adjustment system for plural stations
Inventor: TERUNUMA KAZUAKI
IPC: H04B7/26
Filed: 1988-06-01
Abstract: PURPOSE:To attain the adjustment of phase synchronization even if the phase of an individual information signal is shifted by DELTAT or over by arranging a plural station transmission time slot and an individual transmission time slot alternately and allowing each base station to suppress the transmission of the plural station transmission time slot when the monitor and adjustment of the transmission timing are disabled. CONSTITUTION:A common information time slot and an individual information time slot are arranged alternately in a radio channel shared in common by plural base stations. Each base station uses a reception timing measuring section 7 to measure a difference of the reception timing of the individual information between the reference station and its own station and a phase adjustment section 8 adjusts the transmission timing of its own station. Thus, the phase synchronization of the time slot sent simultaneously by the plural stations is kept. When the phase shift reaches DELTAT or over and is not adjustable, a transmission control section 10 controls the transmission section 9 so as to suppress the transmission of the common information. Then the difference of the reception timing of the individual information between the reference station and its own station is measured and the transmission timing of its own station is monitored and adjusted to keep the phase synchronization.

Filed: 1989-05-26
Abstract: PURPOSE:To record and reproduce a high definition video signal only by means of four magnetic heads at plural recording and reproducing modes by setting the forms of the travel tracks of the magnetic heads to be similar even at a standard mode or a long time mode. CONSTITUTION:Four magnetic heads A(+), B(-), C(+) and D(-) are provided for a rotary cylinder 8 by setting them symmetrical with respect to a rotational center by 90 degrees. Then, recording signals 1 of two channels are respectively supplied to two pairs of the magnetic heads which are symmetrical with respect to the rotational center of the rotary cylinder 8 among four magnetic heads by one channel, and the recording signals of two channels are recorded and reproduced on a magnetic tape 10. Since all recording track patterns of respective magnetic heads are symmetrical, the track patterns do not change even if a tape feed speed changes, and the same magnetic head as for the standard mode can be used even at the long time mode. Thus, a high vision base band signal can be recorded and reproduced at plural recording and reproducing modes only by four magnetic heads.

Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a small and lightweight capacitor bushing which is excellent in mechanical strength and has a simple structure by using silicone rubber for an envelope, and closely sticking the same to a resin paper capacitor portion through an adhesive. SOLUTION: A resin paper capacitor portion 2 surrounds a center conductor 1 made of copper or aluminum, and has an electrode metal foil 2a for adjusting an electric field inside insulating material. The resin capacitor portion 2 to which an adhesive or a surfactant is previously applied is pressed in a silicone rubber whose inner diameter is formed smaller than the outer diameter of the resin paper capacitor portion 2 so as to form an envelope 7. By using the silicone rubber for the envelope so as to heighten adhesion with a resin paper capacitor by the elasticity thereof, no insulation oil is required, a small, lightweight, and simple structure is caused, and the infiltration of contaminants can be blocked. Since no insulator is used, it is possible to obtain a capacitor bushing having superior mechanical strength and high weather resistance.

Title: Testing of oil-immersed transformer
Inventor: NAKATSUKA SHIYOUJI
IPC: H01F27/00
Filed: 1983-07-20
Abstract: PURPOSE:To facilitate assembly and dismantle and performance of testing such as dielectric strength by using a testing core whose cross section is reduced as compared to the proper core at the time of assembly in the factory. CONSTITUTION:A core, which has a cross section necessary for a dielectric strength test is used as the testing core instead of a proper core to facilitate the assembly of the core and the winding for the dielectric strength test of the winding and improve the performance efficiency of the dielectric strength test of the winding. Among dielectric strength tests for an oil-filled transformer winding, an induction dielectric strength test requires a large core cross section. Usually frequency of a source for test is 3-4 times of commercial frequency. Therefore, in the case of the induction dielectric test whose magnification of excitation is about two times, the test can be carried out using the testing core whose cross section is reduced to 2/3-1/2 of the proper value.
