Patent EP-0253296-A2 (EP)
Inventor: YASUDA YUZO
IPC: H04N9/83
Filed: 1987-07-08
Abstract: A frequency converter for a VTR extracts a carrier chrominance signal f S  of 3.58 MHz in a video signal by an BPF 102 and applies the same to a first frequency converter 103. On the other hand, a signal having a frequency of 4.21 MHz which is the sum of a frequency 3.58 MHz of the carrier chrominance signal f S  and the frequency 629 KHz of a low-frequency converted chrominance signal f SL  is applied from a VCO 117. The first frequency converter 103 outputs signals (f S  + f SL ) ± f S  responsive to the signal of 4.21 MHz and an LPF 112 passes signal f SL  of 629 KHz. On the other hand, an output of the VCO 117, together with an output of an VXO 114 which is in synchronization with a burst signal in the signal f S , is applied to a second frequency converter 118. The circuit 118 outputs signals f S  ± (f S  + f SL ) An LPF 120 passes the signal f SL  of 629 KHz. A phase comparator circuit 121 compares phases of the signal f SL  and a horizontal synchronizing signal f H  and controls an oscillating output signal of the VCO 117 in accordance with the phase difference.

Abstract: In the process, magnetic or dye penetration particles or solutions, with or without additives in the form of fluorescent powders or aqueous suspensions, are applied to the test pieces. In the case of the magnetic powder test, they are magnetised and illuminated by a lamp acting as exciting light source with a predetermined spectral amplitude. The light radiated from a surface region of the test piece is automatically evaluated or assessed by a visual test. In the process, the test surface is selectively irradiated (excited) with light in the wavelength range of 400-500 nanometres and the radiated light is selectively assessed in a wavelength range of 500 to 600 nanometres.

Abstract: Aircraft parts such as elevators and rudders, for example, are adjusted with the aid of an electrohydrostatic actuator. An electric motor drives a flywheel which is coupled to a hydraulic, adjustable pump/motor. The pump/motor, which is constructed as a swashplate motor with a variable capacity, is set with the aid of an electric d.c. motor, so that the chambers of a double-acting ram-cylinder unit are actuated via two hydraulic connections in order to adjust the part to be moved, to hold it in the adjusted position, and/or to reset it. During adjustment of the part to be moved, the necessary energy is taken from the kinetic energy stored in the flywheel. During resetting, wind force presses the part back into the initial position. The energy - minus losses - is restored in the flywheel via the ram-cylinder unit. A rotary angle sensor of the d.c. motor serving as actuator for the pump/motor controls the pump/motor, on the one hand, and on the other hand generates a feedback signal which is compared with the actuating signal for the d.c. motor. A very rapid adjustment of the pump/motor is achieved in this way. <IMAGE>

Abstract: A process for forming deposited film, which comprises:
     (a) the step of preparing a substrate having crystal nuclei or regions where crystal nuclei are selectively formed scatteringly on the surface for forming deposited film in a film forming space for formation of deposited film;   (b) the step of forming deposited film on the above substrate by introducing an activated species (A) formed by decomposition of a compound (SX) containing silicon and a halogen and an activated species (B) formed from a chemical substance for film formation (B) which is chemically mutually reactive on said activated species (A) separately from each other into said film-forming space to effect chemical reaction therebetween;   (c) the step of introducing a gaseous substance (E) having etching action on the deposited film to be formed or a gaseous substance (E 2 ) forming said gaseous substance (E) into said film-forming space during said film-forming step (b) and exposing the deposited film growth surface to said gaseous substance (E) to apply etching action threon, thereby effecting preferentially crystal growth in a specific face direction;   (d) irradiating said gaseous substance (E) with light energy during said step (c), and   (e) the step of increasing etching activity of said gaseous substance (E) by irradiation of light energy.

Abstract: The invention provides a door operating mechanism which can be mounted on the pivot axis of a door. The mechanism comprises a casing 1 in which is guided axially a piston 4, and actuating member 6 therefor. Coupled to the actuating member is a pivot member 7. A compact construction results where the actuating member (6) and pivot member (7) have complementary helical fingers (29; 33) whereby rotation of the pivot member (7) gives rise to axial movement of the acuating member (6) and piston (4). The axial movement in one direction causes hydraulic fluid acting on the piston (4) be pressurised which provides a return force acting on the piston (4). This can be used to return a door to a starting position from which it has been displaced. By having fluid acting on the piston (4) instead of a spring, failure of the fluid system does not give rise to slamming of the door which is the case where the fluid merely serves as a damping medium for movement of the door. The construction renders its self-adaptable to automatic operation.
