Abstract: The photoelectronic switch circuit of a pulse-modulated light system is adapted to emit pulse light and to conduct detecting operation by detecting only the photo-reception signal synchronized with the pulse light. It comprises a counter control circuit for resetting or presetting the output signal from a counter if the number of pulse light successively received is less than a predetermined number. Such a photoelectric switch eliminates the effect, if any, of external disturbance light and facilitates to attain the integrated circuit by reducing the number of parts for the circuit constituting portion.

Title: Adjustable double-acting damper
Inventor: HOUGHTON BENJAMIN T
IPC: F16F9/44
Filed: 1986-05-22
Abstract: A dashpot damper for acting between two objects subject to move toward and away from one another includes a housing (12) including an elongated cavity (66), a piston mounted within the housing cavity for reciprocating movement therealong and dividing the cavity into two variable-volume, hydraulic fluid chambers (67, 69), and a network of passages permitting hydraulic fluid to flow between the two variable-volume chambers as the housing and piston move relative to one another in response to relative movements between the two objects. The damper utilizes unitary flow control cartridge (16, 17) mounted within the housing and defining a passageway (186) through which hydraulic fluid is forced to flow when passing between the two variable-volume chambers (67, 69). The flow control cartridge (172) also restricting the flow of hydraulic fluid in one direction through the passageway (186) and for permitting substantially unrestricted flow of hydraulic fluid in the other direction through the passage. By controlling the flow of hydraulic fluid through the passageway (186) in said one direction, the damping effect of the damper is controlled. The flow control cartridge (16, 17) can be constructed so as to provide either an adjustable or fixed restriction to the hydraulic fluid flow in said one direction.

Abstract: A new type of diaphragm valve for controlling fluids is characterised in that at least the inlet region (2) or the outlet region (4) or, however, both regions of the valve are covered by a fluid-permeable supporting wall (12). In a particularly preferred exemplary embodiment, the supporting wall is constructed of two fluid- permeable tube sections (12a, 12b), which are separated by a partition wall (14). In this case, the diaphragm is a hose diaphragm whose diameter is approximately equal to the external diameter of this supporting tube. This construction is surrounded by a tubular housing (10) which carries the inlet and outlet connections (6, 8) for the fluid. The valve constructed basically in this way can be used as a remotely controlled diaphragm valve, a diaphragm valve controlled by its own pressure, and, with minor conversion, also as a direct-acting 2/2 electromagnetic through valve or as a non-return valve.

Abstract: A solid-state image pickup device comprises a semiconductor substrate (1) of a first conductivity type, and a photoelectric cell including an impurity region (17,18) of a second conductivity type formed on the semiconductor substrate to produce a signal charge corresponding to the quantity of an incident light at a first junction surface between the impurity region of the second conductivity type and the semiconductor substrate. The device further comprises an impurity region (3) of the first conductivity type formed on the semiconductor substrate to effect isolation between the impurity regions of the second conductivity type, and a charge transfer unit (4, 5) for transferring the signal charge produced in the photoelectric cell. This device is characterized in that the impurity concentration of the impurity region of the second conductivity type is high in the vicinity of at least a portion of a second junction surface between the impurity region of the second conductivity type and the impurity region of the first conductivity type and is low in a range spaced from the second junction surface. With the device thus configured, under a highly reverse-biased condition due to the charge transportation, the high concentration portion of the impurity region of the second conductivity type is depleted, and under a low reverse-biased condition at the time of the charge accumulation, the high concentration portion is placed in a non-depleted condition. This permits the junction capacity at the time of the charge accumulation to be large, thus enabling realization of a solid-state image pickup device having less afterimage.

Abstract: A diffraction grating comprises a birefractive sheet (ll) having a corrugated surface with at least each groove filled with a mass (l2) of a material of a refractive index which is substantially equal to one of ordinary and extraordinary indices of the birefractive sheet. The diffraction grating is effective in an optical head device when made to have a plurality of grating regions of different patterns of corrugations. In this event, a linearly polarized beam should be supplied to the diffraction grating with electric vectors directed parallel to those of ordinary and extraordinary components when the refractive index is substantially equal to the ordinary and extraordinary indices, respectively. Alternatively, such an optical head device may comprise a reflection grating in which reflective corrugations are substantially parallel in the respective grating egions. In this event, a linearly polarized beam is supplied from an optical source to the reflective corrugations as a p-polarized beam. When either the birefringence grating or the reflection grating is used, the optical head device should further comprise a quarter-­wave plate for receiving the linearly polarized beam which is exit from the grating.

A control circuit (30) supplies corresponding residual phase error data from the memory to be used in compensating a present phase error signal whereby the high frequency time base fluctations may be removed, and further mixes the present phase error signal with corresponding residual phase error data to generate new residual phase error data for storage in the memory in place of the original residual phase error data.

Abstract: Each aircraft is fitted with two antenna units (A1, B1 and A2, B2) laterally spaced by a distance S and each comprising longitudinally spaced sharksfin radiators. The two antenna units are energised together to transmit a directional interrogation pulse (P1/P3) into the airspace forward of the aircraft. An intermediate sidelobe suppression pulse (P2)is transmitted from a non-directional antenna (C). Each aircraft is also equipped with a transponder and an aircraft correctly interrogated by the interrogation pulse sends a reply. The reply is received at the two antenna units of the interrogating aircraft. The round time delay enables the range of the responding aircraft to be determined while the relative phases of the reply at the two antennas enable the azimuth of the aircraft to be determined interferometrically. Information gathered in this way is processed to detect aircraft on potential collision courses and these are shown on a display device. An audible warning is given to alert the pilot to any aircraft which is close and on a potential collision course.

Abstract: The invention provides a method of permanently assembling a rubber tap connector l to a hose 6 using a cyanoacrylate adhesive, which has been found to be both acceptable in performance and life, and economically practicable. In order to overcome potential problems of mechanical failure and leakage in use, it is preferred to apply adhesive both to the interior of the connector l and to the exterior of the hose 6 prior to engagement of the hose 6 in the connector l. The adhesive is thus conveniently applied as a ring 8 or 9 in each case, and the rings 8,9 are c            aused to merge during the engagment of the connector l and the hose 6. Such a procedure leads to an improvement in the mechanical strength and overall performance of the assembly. It is further preferred to provide for clamping of the hose 6 onto the connector l after application of adhesive and assembly, so as to ensure intimate contact between the surfaces to be bonded.
