Title: Control message in radio communication
Inventor: TIMOTHY MOULSLEY
IPC: H04J1/00
Filed: 2016-07-20
Abstract: PROBLEM TO BE SOLVED: To provide a method that can prevent a terminal from erroneously responding to a control message in a radio communication system.SOLUTION: In LTE TDD adopting carrier aggregation CA, a method attaches a sequence number with two bits or downlink allocation indicator (DAI) to a downlink control information (DCI) message about a packet transmitted on some or all of consecutive carrier frequencies at a given sub-frame. The sequence number increases or decreases for each piece of transmitted DCI depending on whether the total number of DCI messages transmitted at the given sub-frame is an even number or odd number. This allows the loss of any three-consecutive pieces of DCI (not including the last DCI) to be detected. The loss of the last DCI in the sequence is also detected without adding a bit any further.SELECTED DRAWING: Figure 5

IPC: F04B43/02
Filed: 2016-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a technology for improving a pump efficiency of a diaphragm pump by reducing a dead volume of a pressure chamber as much as possible.SOLUTION: A pump 10 comprises a valve plate 30 having an intake valve 31 and a discharge valve 32; a diaphragm 40 oppositely arranged at the valve plate; and a piezoelectric element 60 adhered to the other surface of the diaphragm through a thermosetting adhesive agent 70. A peripheral edge part 40a of the diaphragm is adhered to the valve plate. The diaphragm has a larger coefficient of thermal expansion than that of the piezoelectric element. Due to this fact, after elapsing a heating step to harden the adhesive agent, a dome-like inflation is generated at the central part of the diaphragm. Such a deformation of inflation and shrinkage of the diaphragm enables a chamber 80 of quite small dead volume to be formed between the diaphragm and the valve plate opposing against the diaphragm.SELECTED DRAWING: Figure 3
