Title: A switchable inductor
Inventor: ZHOU SHU-ANG
IPC: H01P3/08
Filed: 1998-08-27
Granted: 2000-05-21
Abstract: An inductor for microwave frequencies is constructed of a transmission line designed as a linear microstrip element made of a central line (5) comprising normal electrically conducting material, such as a suitable metal. The microstrip element has a width which is varied by making areas (7) at sides of the central line (5) superconducting. In changing the effective width of the microstrip the inductance thereof is changed accordingly. The areas at the sides of the microstrip element are located directly at the central, normal metal conductor. These areas have in the non-superconducting state some electrical conductivity which can be rather low but owing to the fact that they contact the normal central metal conductor only at a very narrow edge instead of contacting it at a large surface they do not significantly affect the transmission characteristics of the transmission path when the superconducting areas (7) are in their normal state.

Granted: 2001-04-11
Abstract: When the synchronous delay circuit is applied to the device such as ASIC having the clock delay amount different from one chip to another, it is not necessary to design the clock driver dummy for each interconnection design modification, and therefore, a design efficiency and a precision can be elevated.

Title: Stereo camera
Inventor: INABA MINORU
IPC: G03B21/64
Filed: 1998-11-25
Granted: 1999-06-11
Abstract: A stereo camera capable of showing an accurate stereo image by improving the accuracy of the position of the negative mounted in the stereo slide frame. For obtaining an appropriate perspective view, the position of a projection image of the detectable negative hole relative to the focus plate is controlled by a detection device projecting a negative image on the left and right focus plates and adjusting the clearance between the left and right projection images until an accurate perspective view is found. A printing device 81 drives a printer head 87 based on the detected position data, and prints out a pointer on the negative frame 41a of the stereo slide frame for the hole completing the positioning operation. The mounting of the negative is completed when the pointer on the negative frame 51a is consistent with the hole of the negative. Under such a status, the set-off amount of the negative image relative to the image window of the stereo slide frame is fixed at a value equivalent to the set-off amount of the projection image relative to the focus plate. The position can be measured by the detection device.
