Title: Data transmitter, data receiver, data communication equipment and data communication method
Inventor: SAKURADA KOSHI
IPC: H04N19/70
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To reflect changes in a transmission band on communication control even under a condition that the transmission band changes dynamically by controlling an encoding processing and/or a transmission processing based on control information to be informed from a transmission destination. SOLUTION: Transmission is performed by inserting a test packet with size different from an encoding packet into a group of the encoding packets to be transmitted by an information transmitter 101 at a transmission side and the transmission band S is estimated by utilizing difference in two kinds of packet size by an information receiver at a reception side. And information to estimate the transmission band is informed to the information transmitter 101 by the information receiver 102 by which the transmission band S is estimated. Thus, quality of the information to be transmitted and quantity of codes are properly controlled and a load of a communication network is normalized without falling into a congested state even when the transmission band S dynamically changes by the information transmitter 101.  Thus, stable quality is maintained even when real time continuous information like a video signal and an audio signal is transmitted.

Abstract: PURPOSE:To improve reliability in relation to destruction and high temperature abrasion property resistance by applying a plating layer whose main component is Ni, on the outer circumference surface of a lifter main body made of aluminium alloy, which has good high temperature strength and tenacity. CONSTITUTION:The base 10 of a lifter main body is made of a compound material containing Cu; 3 to 8%, Mg; 0.5 to 2.5%, Si; 0.2 to 1.5%, in which the total amount of one kind or two kinds or more of Mn, Fe, Cr, Co, V, Zr, Ti should be 3 to 10%, and the balance substantially consists of aluminium with hard particles 10a of an average particle diameter 2 to 30 mum, dispersed from 2 to 10% in a volume ratio. The outer circumference of the base 10 is covered with a plating layer 10b whose a main component is Ni. Since, the base 10 has strong fatigue strength, and reduction of strength is small even if it is maintained at a high temperature for a long time, its reliability is enhanced at the time of the same shape. And reduction of abrasion resistance property is small in the state of sliding on an outer shim, even if it is exposed to a high temperature for a long time by the hard particles 10a and the base 10 whose high temperature strength is high.

Abstract: PURPOSE:To prevent the deterioration of functions of a sleeve as a Spertopf and a half-wavelength dipole antenna by covering the exposed part of a core wire and the outer surface of the sleeve with a covering material made of a dielectric or magnetic substance. CONSTITUTION:The cylindrical space formed between a sleeve 2 and a coaxial cable 1 is filled with a dielectric cylinder 7 of 'Teflon (R)', etc., and a magnetic cylinder 8 of ferrite, etc. Then a core wire exposed part 1a and the outer surface of the sleeve 2 are covered with covering materials 5, 6 made of a dielectric or magnetic substance respectively. In such a constitution, the wavelength is reduced like the inside of the sleeve 2. In this respect, the dielectric constants, the magnetic permeability, and the thickness of the materials 5 and 6 are properly selected. Thus it is possible to secure the coincidence of shortening degrees of wavelength between the inside and the outside of the sleeve 2 and to reduce the inside and outside wavelengths of the sleeve 2 less than the resonance wavelength. In other words, the sleeve 2 can ensure the satisfactory function as a Spertopf without deteriorating the function an antenna with regard to the radiation of radio waves, etc.

Title: Magnetic resonance method and local coil means for magnetic resonance apparatus
Inventor: JIYOOJI JIEI MISHITSUKU
IPC: G01R33/341
Filed: 1988-11-11
Abstract: PURPOSE: To improve Q of coil, by electrically connecting an internal conductor which constitutes a first current path with an external conductor which constitutes another current path along the internal conductor and on the periphery of it, and termini of both the internal and external conductors. CONSTITUTION: The local coil itself is a conductor loop of closed coaxial structure. On a terminal of the loop, the internal conductor 30 is short-circuitted 34 by the external conductor 32. The latter consists of copper-pipe segments 32 which become discontinuous at the gap, i.e., opening 50. The internal conductor 30 is a magnetic core placed in the center of a coaxial cable isolated from the external conductor 32 by a dielectric insulator 52. Self-resonance of the coaxial cable depends on a fairly large extent upon the inductance of the internal conductor and the shunt capacitance to the exterior of the central conductor. When the shunt capacitance is reduced, self-resonance and Q value of the coil increase.  The shunt capacitance can be reduced by increasing the diameter of the external conductor or by decreasing the dielectric constant of the insulator 52 of the internal conductor.

Abstract: PURPOSE:To complete the insertion of a glass rod into a glass tube without contact of both materials by providing a supporting member for hanging the freely rotatable glass rod and a mechanism for positioning the member in the two horizontal directions. CONSTITUTION:The glass rod 1 is lowered and inserted into the glass tube 2, and a gas is simultaneously supplied into the tube from a gas feeder 5. When the insertion is continued, the gas pressure increases as the flow resistance increases, hence buoyancy is exerted on the glass rod 1, the weight exerted on the support 14 is gradually decreased, and finally the buoyancy exceeds the gravity of the glass rod 1. At this time, since an insertion frame 11 continues lowering, the glass rod 1 is raised with respect to the insertion frame 11. The ascension is detected by the glass rod end position detector 17 provided to the insertion frame 11. A support opening and closing device 15 is controlled by a controller 19 based on the detection signal, and the support can be completely released without imparting any shock when the glass rod 1 is released.
