Title: Millimeter wave imaging device.
Inventor: HUGUENIN G RICHARD
IPC: H01L29/872
Filed: 1988-11-04
Abstract: A millimeter wave sensing device is disclosed comprising a local oscillator source generating a millimeter wave signal which is mixed with millimeter wave radiation reflected from or emitted by objects in a field of view. The mixing is performed in a staring array of mixer/detector elements which need not be mechanically or electronically scanned to generate signals responsive to the entire field of view. In a first embodiment of the invention, the device detects millimeter wave radiation emitted by or reflected from the object to be imaged. In a second embodiment of the invention, the oscillator used to provide the local oscillator signal is also used to illuminate the field of view. In the second embodiment of the invention, the oscillator signal is preferably linearly polarized, and a polarizing grid is used to separate the local oscillator signal and illumination beam and direct them in a simple and efficient manner. A twist reflector may also be used to rotate the polarization of a portion of the beam to direct it onto the mixer/detector array for mixing with the received signal from the field of view. Improved constructions of millimeter wave source and mixer/detector elements are also disclosed, which greatly simplify construction of the device.

Abstract: A synchronization control system for carrying out synchronized and superposed operation among different systems of multi-system control machine tools. A follow-up error ( epsilon 3) of a servomotor for the superposition instruction is simulated to determine the difference in error by subtracting the follow-up error ( epsilon 3) for the superposition instruction from a follow-up error ( epsilon 2) of a servomotor (32) of a superposed operation axis (Z2), and the above difference is compared with a follow-up error ( epsilon 1) of a servomotor (42) of a synchronized operation axis (Z1) to detect alarm. This makes it possible to check deviation in synchronism during the superposed operation.

Abstract: A method of making thermal insulating products comprising porous, lightweight, high temperature resistant inorganic particles (92) in a polyimide foam matrix (94) and the product thereof. A polyimide precursor powdered is mixed with about equal weight of flake-like porous inorganic particles to substantially uniformly coat the particles with powder. The mixture is placed in a mold and compressed slightly. The assembly is heated to the foaming temperature of the polyimide precursor for a period suitable to produce uniform foaming. Then the temperature is raised to the curing and crosslinking temperature of the precursor for a time period sufficient to produce complete cure. A high temperature and flame resistant, light weight, highly insulating product results. If desired, protective sheets of material may be bonded to selected product surfaces during or after the molding operation.

Abstract: The shear (11) for shearing laminar elements (35) or the like comprises a pair of blade-holders (31, 32), which, during the shearing operation, are stressed by two forces (F x  and F y ) perpendicular to each other and having as their resultant, the force F R . At the shearing time, both of said blade-holders (31, 32) are supported in an inclined position, so that their main axes (20, 21) come to coincide with the direction of said resultant force (F R ). From the above, the possibility results that the mass of the inclined blade-holder can be reduced even by 50% relatively to the mass of a traditional blade-holder which is not inclined, without the stiffness of said blade-holder, relatively to the shearing forces, being endangered. 
     The invention can be applied as well to guillotine shears and to rotary shears (45) equipped with roll blade-holders.

Abstract: A vacuum sewer arrangement comprises a bowl (1) connected to a sewer pipe (2) provided with means for establishing, in the sewer pipe (2), a vacuum sufficient for obtaining efficient sewage transport. There is a normally-closed sewer valve (3) connecting the bowl (1) to the sewer pipe (2) and a control device (7) for controlling operation of the sewer valve (3) to allow discharge of sewage from the bowl (1) to the sewer pipe (2). There is also an air inlet duct (4) for letting air into the sewer pipe (2) separately from the bowl (1). For controlling flow of air through the air inlet duct (4) into the sewer pipe (2), when the sewer pipe (2) is under proper vacuum for effective sewage transport, there is an air inlet valve (6) with means operating it in response to pressure variations in the sewer pipe (2). Such pressure variations occur when the sewage discharged from the bowl (1) has passed the point (36) where the air inlet duct (4) is connected to the sewer pipe (2). This ensures that the air inlet valve (6) operates accurately and securely.
