Title: Interference wave eliminating system of weather radar
Inventor: HAGIWARA MORIYA
IPC: G01S13/95
Filed: 1983-09-16
Abstract: PURPOSE:To ensure the operation of an interference wave eliminating circuit by delaying a received echo by a time corresponding to one radar period before its averaging processing and eliminating this received echo signal if the intensity difference between this echo signal and a received echo due to the next radar hit exceeds a prescribed value. CONSTITUTION:The received echo which is converted by an analog-digital converting circuit 6 and includes interference waves is delayed by a time corresponding to one radar period by a delay circuit 14, and a digital quantity for every range bin as a reference is stored in a memory circuit 15. The intensity of the received echo in every range bin is compared with that of a next inputted received echo due to the next radar hit. If the intensity difference between both echoes which is obtained by the comparing circuit 16 exceeds a preliminarily set threshold, this echo is eliminated to eliminate surely only the echo due to interference waves. The received echo where interference waves are eliminated in this manner is subjected to processings in a circuit 7 and following circuits, and the result is displayed on a display device 12.

Title: Molding method for injection molding
Inventor: KURINO YUKINORI
IPC: B29C45/17
Filed: 1990-06-28
Abstract: PURPOSE:To apply sufficient dwell to resin in a cavity and prevent the generation of sink marks by increasing the clamping pressure, providing the compression process for closing a mold which is slightly opened in the gas injection process and molding. CONSTITUTION:The molding method for the subjection injection molding is first injecting into a cavity of a mold by the short shot and filling therein. Then, pressurized gas is injected into the molten resin filled in the cavity through an injection nozzle of a molding machine or a suitable support in the mold. At that time, the mold is opened slightly by the injection of pressurized gas. Then, the slightly opened mold is closed completely by increasing the mold clamping force putting up resistance to the pressure of pressurized gas. The pressure of pressurized gas and the molding clamping pressure are applied to the resin in the cavity by said arrangement, and sufficient dwell can be applied even to the sites where the gas is not infiltrated by the action of both pressures. The generation of sink marks caused by the heat shrinkage can be prevented by said dwell.
