Abstract: In an electronic chip placement machine (60) with test function, there is provided a suction nozzle (4) for holding a chip (5), a chip-regulation device (7) for regulating the attitude of the chip by clamping the chip at portions having no electrodes (5a, 5b), probes (l4a, l4b, l5a, l5b) for testing electrical characteristics of the chip. The tip portion (4a) of the suction nozzle is made of an insulating material such as a ceramic or a synthetic resin in order to avoid a short-circuit between electrodes of the chip through the nozzle. Therefore, the electrical characteristics of the chip can be tested without the separation between the nozzle and the chip. Furthermore, since one cycle of the operational process come to short, it is possible to provide chip-test and placement machines whose structure is simple. As a result, productivity and durability can also be increased.

Abstract: An Intervention Flight Management System (IFMS) that allows a pilot to intervene in the operation of a preprogrammed flight management computer and change the speed and/or flight path of an airplane in response to air traffic control (ATC) instructions is disclosed. The IFMS includes an IFMS control panel via which the pilot interfaces with an IFMS program. The IFMS program includes intervention subroutines that override the preprogrammed instructions that control the flight management computer. The intervention subroutines include a lateral (direction) control subroutine and several vertical subroutines. The vertical subroutines include altitude, speed and vertical path subroutines. The intervention subroutines can be engaged independently of one another. Control axes unrelated to an engaged intervention subroutine remain under the control of the preprogrammed flight management computer instructions.

Abstract: The invention relates to devices for taking up axial and radial play and to a self-operating system for improving the volumetric and mechanical efficiency of an oscillating piston-type volumetric pump. A radial compression component (3) presses a piston (1) against a body (2). An axial compression component (8) presses on a front plate (10) containing a pressure-equalizing aperture (11), which presses the piston (1) onto a rear plate (12). The piston (1) has a slit in which an elastic component produces firm contact of the piston with a diaphragm (19). A rotating glass component (27) bears permanently on a fixed abutment (24) thus forming a sealing gasket. These devices are intended especially for volumetric pumps carrying out high and low pressure transfer operations in chemistry and parachemistry. The flow rate may be fixed or variable.

Abstract: An output circuit of a stimulator, generating bipolar pulses of current, finding application in diagnosis and therapy in medicine. The invention consists in applying, in the output circuit of a stimulator, one voltage-con­trolled current generator /5/ being switched on between the first bus-bar /6/ and a bridge comprising four elec­tronic keys /1/, /2/, /3/ and /4/, which is with the op­posite end connected to the other bus-bar /7/. The two re­maining points /9/ and /10/ of the bridge constitute the output of the stimulator, whereto the impedance /13/ of a patient is connected. 
     The appropriate sequence of the control run as set up from a control system /11/ makes a two-directional pulse of cur­rent flow through the impedance of a patient. 
     Such a solution ensures preferable symmetry of the output pulse with regard to the shape and load of the both phases, and its stability in time as well as it facilitates the process of aligning the stimulator.

Abstract: The method for forming Fresnel lens according to the present invention is such that a Fresnel lens comprising a body with a frontal surface having a plurality of annular Fresnel-type prism elements concentrically disposed thereon and a back surface formed substantially flat is formed from a molten sheet glass. The method comprises a step of preparing cavities of which the shapes are derived from inversion of the shapes of the plurality of annular Fresnel-type prism ele­ments, a step of disposing the molten sheet glass on a stationary mold having a substantially flat surface, a step of pressing the molten sheet glass with a moving mold having the cavities to make a portion of the molten glass flow into said cavities, and a step of solidifying the molten glass and removing the moving mold thereafter. The shapes of said cavities are previously designed so that portions of the molten glass corresponding to the Fresnel-type prism elements flow substantially only within small area corresponding to the corresponding Fresnel-type prism elements while the sheet glass is being pressed. This method permits to minimize surface defects such as wrinkle caused during forming, reduce the time required for forming, and to form a Fresnel lens having excellent optical properties.
