Title: Facsimile equipment
Inventor: TSUMURA NAOKI
IPC: H04M11/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten transmission time and to improve the convenience of a user by informing an opposite party of a reception file ID number unique to each incoming call as the CSI of a present equipment. SOLUTION: In transmission from the opposite party, RING is detected first. At the time, whether or not a following transmission means is binary file transfer(BFT,) the reception file ID number is updated. The concrete means of updating takes out a latest reception file number from a communication management area 30a in a system memory 30 first, adds '1' and then, stores it in the communication management area 30a again. Then, as CSI information, the updated reception file ID number is transmitted. In the case that a negotiated result is BFT transmission, the reception file ID number is attached and a reception file is stored in a BFT reception file area 30b.  Thus, a reception file ID is recognized without the need of providing a special function on a transmission origin, it is displayed at an operation part during transmission as well and it is written in a communication management report on a transmission side.

Title: Multiconductor transmission line
Inventor: YOSHIDA SATORU
IPC: H02G7/14
Filed: 1992-11-24
Abstract: PURPOSE:To effectively prevent the occurrence of corona noise by preventing spacers which support the subline conductor of a transmission line from generating heat and, at the same time, relieving the potential gradient between the main line conductors and subline conductor of the transmission line. CONSTITUTION:A subline conductor 14 of this transmission line can be maintained at the same potential as those at the main line conductors 12A and 12B of the transmission line on the ground-side, since the subline conductor 14 is supported by the main line conductors 12A and 12B through conductive spacers 16A, 16B, and 16C. Therefore, the surface potential gradients between the main line conductors 12A and 12B decrease and the occurrence of corona noise can be effective reduced. In addition, since the impedance of the subline conductor 14 is increased due to the reactance of a current transformer 20 installed to the subline conductor 14, the current separated to the subline conductor 14 from the main line conductors 12A and 12B can be suppressed. Therefore, the conductive spacers 16A, 16B, and 16C can be effectively prevented from generating heat.

IPC: G01B21/30
Filed: 1989-12-27
Abstract: PURPOSE:To measure a plane shape with high accuracy by processing measured values obtained by 4 - 6 displacement detectors throughout one rotation of an object to be measured. CONSTITUTION:The six displacement detectors 21 - 26 are arranged at specific angles alpha1, alpha2, beta1, beta2, and delta concentrically about the center O of rotation of a surface to be measured. Then the detectors 21 - 26 measure the surface unevenness of the surface to be measured throughout one rotation of the object to be measured as the object to be measured rotates. A composite measured quantity Y(phi) shown by an expression is found from those measured values. The measured quantity Y(phi) is developed into a Fourier series to find the coefficients Fj and Gj of the cosine and the sine components. These coefficients Fj and Gj are used to find the surface uneven shape of the surface to be measured from the specific expression. Even if a motion error such as axial motion and angular motion is generated during the measurement, the surface uneven shape of the object surface can be measured without being affected by their influence. In this case, preferably 4 - 6 displacement detectors 4 - 6 are provided.

Title: Center feed antenna
Inventor: NAZUMI TATSUO
IPC: H01Q1/12
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of antenna performance by constituting the center feed antenna of a dielectric composite materiel and constituting its cross-sectional shape so that a distance between a 1st reflection face representing a surface side reflection face and a 2nd reflection face repressing a rear side reflection face is included within a specific range for the wavelength of frequency to be used. SOLUTION: The center feed antenna has the 1st reflection face 5a representing a reflection face for all radio waves reflected by the surface side of supporting structure 2 and the 2nd reflection face 5b representing a reflection face for all radio waves reflected by the rear side, the distance between the reflection faces 5a, 5b is set to be an odd multiple of 1/4λ, e.g. 5/4λ, where λis wavelength. Since the supporting structure with the radio wave passing range in the center feed antenna having the structure is constituted of a dielectric substance, the most part of radio waves are transmitted through the supporting structure and the deterioration of electric performance is reduced.  Even in the case of reflected waves not transmitted, the pass difference of reflected waves reflected by the 1st and 2nd reflection faces becomes 5/4λ×2=10/4λ=2λ+1/2λ and reflected waves having approximately reverse phases are mutually offset, so that the deterioration of electric performance of the antenna is reduced.
