Title: Preparation of tube for blood circuit
Inventor: ISHIHARA YOSHIHISA
IPC: A61M1/00
Filed: 1987-09-11
Abstract: PURPOSE:To prepare a tube for a blood circuit permitting the smooth flow of blood without generating the stagnation or turbulent flow of blood, by changing an extruding condition when the tube is molded by the melt extrusion of a synthetic resin to form parts having difference diameters to one tube. CONSTITUTION:A synthetic resin is heated to melting temp. or more in a molding machine to be extruded into a tubular shape from a die in a molten state. At this time, a hollow state is held by blowing gas in the extrudate but, when the pressure of flow rate of the gas is enhanced, the diameter of a tube is increased and the wall thickness thereof is decreased. Since the an extruding condition is correlated not only with the relation between the diameter and wall thickness of the tube but also with a synthetic resin to be used and the melting temp. thereof, the die of a molding machine or the like, a molding condition is determined in comparison with the shape of the tube to be manufactured. The obtained tube for a blood circuit is constituted of a fine diameter part 2 and two kinds of large diameter parts 3, 4 and the diameters are smoothly changed at the boundaries of the parts 2, 3, 4 and, therefore, the generation of the stagnation or turbulent flow of blood at said parts is reduced and a thrombus is hard to generate and the tube pref. as the blood circuit is obtained.

Title: On-load tap switching unit
Inventor: SODA KOUJI
IPC: H01F29/04
Filed: 1983-11-30
Abstract: PURPOSE:To enable tap switching in inphase and negative-phase regions by detecting a zero point of voltage as well as that of electric current while discriminating inphase and negative-phase regions and by controlling SCR gate signals with a logic circuit. CONSTITUTION:SCRs 1-4 connected in back to back relations and non-linear resistances 51 and 52 are connected to taps of a voltage regulator 32, and zero points of voltage and electric current of a charge 53 are detected at the circuit 57. When the tap voltage Us and current Il from a low potential 8 to a high potential 7 are stepped up in an inphase region or region near there, or stepped down in a negative-phase region or region near there, the Il is transferred in the region which is not near the zero point of the voltage or current. When they are stepped down in an inphase region or stepped up in a negative-phase region, the conductance in the SCRs is forcedly commutated by a recovery voltage generated in the non-linear resistances 51 and 52, whereby the SCRs of the other tap are caused to conduct and thus the Il is transferred to switch the taps. The gate control of the SCRs are performed by logically processing at logic circuit 56 zero-point detection signals 57, phase discrimination signals 54 based thereon and stepping-up-or-down instruction signals 55. According to this constitution, tap switching can be enabled in a phase region where it is unable with the prior art.

Title: Frequency offset compensation system
Inventor: UEDA TAKASHI
IPC: H04L27/227
Filed: 1991-09-09
Abstract: PURPOSE:To improve the deterioration in the detection characteristic due to a frequency offset by estimating the magnitude of the frequency offset from a time change rate of a mean phase of plural partial series extracted from a unique word series. CONSTITUTION:An IF signal inputted to a detection circuit is divided into two signals at a branching device 1 and they are fed respectively to mixers 2-1, 2-2, the outputs are subject to band limit by low pass filters 5-1, 5-2 respectively and converted into digital signals by A/D converters 6-1, 6-2 and stored in a memory 7. A digital signal processor (DSP) 8 reads a partial unique word series from the memory 7 to obtain a mean phase in a signal space as to plural partial unique word series. Then the magnitude of a frequency offset is estimated from a time change rate of the mean phase. Thus, a deviation between a carrier frequency of a reception signal and a local oscillation frequency of a receiver is reduced.
