IPC: B22D17/02
Filed: 2000-05-31
Abstract: Disclosed is an injection unit for a hot-chamber pressure die casting machine, providing an electromechanical drive for the plunger. A spring element (16) in the form of a plastic component or a hydraulic spring is inserted in between the plunger and the connecting rod (9) in order to absorb the moments of inertia which occur when the plunger drive mechanism is shifted from the phase in which the mould is filled to a pressure dwelling phase. Said spring element is compressed by the additional travel of the connecting rod after the motor is decelerated. The extent of said compression can be selected in such a way that the resulting axial force which is exerted upon the plastic component or hydraulic spring suffices to create the desired pressure dwell in the melt.

Title: Method and system for re-setting call communication system
Inventor: GAFRICK JOHN MATTHEW
IPC: H04W4/90
Filed: 2001-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a method and system for resetting an interrupted call from a mobile unit. SOLUTION: This invention provides a method for resetting a call in a communication system and a mobile unit switching center(MSC). The MSC receives a loopback call request from a network element so as to reset a call such as an emergency call between the network element and a mobile unit. The loopback request has a loopback number. The MSC decides whether the loopback number can be used for warning a mobile unit. When the loopback number cannot warn the mobile unit, the MSC decides an identification number of the mobile unit. Then the MSC uses the identification number of the mobile unit to warn the mobile unit and resets a call between the mobile unit and the network element on an initial call path.

Filed: 2001-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a chirped grating type optical fiber which can be easily manufactured, has flat wavelength characteristics and can be precisely adjusted for the wavelength dependence of the transmittance, and to provide a method for manufacturing the filter. SOLUTION: The optical filter can be easily designed and the transmittance characteristics depending on the wavelength can be arbitrarily controlled by dividing the whole chirped grating 11 into a plurality of regions A1, A2, A3, etc., so as to make use of the characteristics of a chirped fiber grating in which the Bragg wavelength varies and by making one-to-one correspondence between the transmittance at the center Bragg wavelength of each region and the amplitude of the chirped grating 11 in each region A1, A2, A3, etc. Moreover, since the coupling between the ground level modes propagating the core is used, the temperature dependence is reduced to 0.01 nm/ deg.C. In the manufacture of the grating 11, a method using excimer laser light 12, a phase mask 14 or the like can be used similarly in the manufacture of a narrow band fiber grating.  This means no requirement for large changes in the manufacture techniques.

Then the remote controller 4 starts counting when receiving a WWW site access from the user and deactivates functions of operation buttons other than 'cancellation' and 'end'. When no desired picture appears even a lapse of a prescribed time, the remote controller 4 informs a user about a state of access waiting. A display section 47 visually displays this notice for the user.
