Title: Pn code synchronization device, receiver and communication method
Inventor: SUGIMOTO MASAKI
IPC: H04B1/707
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a PN code synchronization device that can more quickly and surely acquire a synchronizing signal. SOLUTION: A transmission epoch denoting a head of a spread code at a transmission side of a modulation section 1 is synchronously with a timing of an inverse spread signal generated from an inverse signal generator 700 of a demodulation section 2 and the generator 700 outputs an inverse spread signal whose timing is coincident with the synchronized timing. A correlation value detector 400 outputs a shift control signal that shifts a phase of the inverse spread signal to detect a correlation between the received spread signal and the inverse spread signal whose phase is shifted by a spread phase shift circuit 800, and a synchronization discrimination device 500 discriminates the synchronization based on a level of the output correlation.  Since a time of a radio wave returning to a ground station from a satellite is known in advance, the time is held and the initial phase of a PN code is captured before and after the known time to attain the capture in a short time in the unit of bits.

Title: Molding method for resin and mold therefor
Inventor: MATSUMAE MASATOSHI
IPC: B29C45/83
Filed: 1992-11-14
Abstract: PURPOSE:To largely reduce an injecting or extruding pressure, to reduce in size an injection molding machine itself and to decrease in weight and cost of the mold by forming a fluidized lubricating layer having no compatibility with resin on a surface in contact with resin of a resin molding part, and supplying the resin from a molten resin supply unit. CONSTITUTION:When resin 7 is fed from a nozzle 9 to a sprue 5, high pressure air is simultaneously supplied from a high pressure air source 17 via an air pipe 14a. The supplied air is stored in an air reservoir, injected from a vent hole on a surface of a porous layer material 19a to the sprue 5 to form a uniform air layer to the molten resin 7. That is, a skin part of the fed molten resin 7 is cooled to lose its fluidity, but an air layer exists between the skin part in which the fluidity is lost and a surface of the mold. Since the air has extremely small viscosity, a frictional coefficient between the resin 7 and the mold is very small. As a result, injecting or extruding pressure at the time of charging the resin 7 in the mold can be very reduced.
