Title: Hydraulic boosting device
Inventor: SHIMADA MASAHIRO
IPC: B60T13/14
Filed: 1997-11-24
Granted: 2000-09-11
Abstract: In a hydraulic boosting device according to the present invention, when the pressure stored in an emergency accumulator is less than a set pressure, the energized force of a spring 75 exceeds the active force caused by the stored pressure so as to move a stepped piston 70 downward, a throttle valve 72 is set in a first position where the throttle valve 72 is seated in a valve seat 71, and hydraulic fluid flowing from a pump through an inlet path 14 to a control valve 43 is restricted by a flow limiting valve 68 consisting of the throttle valve 72 and the valve seat71, so as to develop a fluid pressure in an annular path 73. The fluid pressure is stored in the emergency accumulator through a path 69, an accumulator valve 27, and an accumulator path 31. When the pressure stored in the emergency accumulator 9 exceeds the set pressure, the active force caused by the stored pressure is larger than the energized force of the spring 75 so as to move the stepped piston 70 upward, the throttle valve 72 is set in a second position where the throttle valve 72 is apart from the valve seat 71, and the hydraulic fluid flowing from a pump 6 to the control valve 43 is not restricted by the flow limiting valve 68 at all so as to flow freely in the control valve 43. In this state, no fluid pressure is developed in the annular path 73, and no stored pressure is developed in the emergency accumulator 9. The object of the present invention is to provide a hydraulic boosting device which is of open-center type, has a pump for supplying fluid pressure to the hydraulic boosting device, can store a predetermined fluid pressure in an emergency accumulator in which an emergency fluid pressure for actuating the hydraulic boosting device is stored, has a simplified structure and improved reliability, and can be manufactured with low cost.

Title: Creating an expanded stereo image using phase shifting circuitry
Inventor: SCHOTT WAYNE M
IPC: H04S1/00
Filed: 1998-03-09
Granted: 2000-06-21
Abstract: In portable stereo radio receivers and television receivers, the loudspeakers therein may be separated only by a limited amount  This severely restricts the stereo image created by the  loudspeakers. A circuit arrangement for creating an expanded stereo image may be incorporated in such receivers.  This circuit arrangement first forms a combined monaural signal and a differential signal from the two stereo signals. The differential signal is then subjected to a phase shift. The phase-shifted differential signal is then matrixed with the combined monaural signal to form output stereo signals.  When reproduced through stereo loudspeakers, the stereo image appears to be greatly expanded, beyond the limited placement of the loudspeakers.
