Title: Deflection system for vidicon camera - has two focal points and focussing field one-and-half times longer than effective deflection field
IPC: H04N3/26
Filed: 1972-04-20
Abstract: The deflection system, for a vidicon camera tube, produces a first focal point inside the deflection field at a point where the electron beam has already experienced some considerable deflection, and there is a second focal point in the plane of the signal plates. The focussing field has an effective length that extends up to the signal plates and is somewhat longer than 1.5 times the effective length of the deflection field where effective length is taken to mean the length of a constant field that has the same effect on the electron beam. Both deflection and focussing fields are magnetic.

Abstract: Inflatable cuff for measuring haemodynamic values comprises a fabric in twill weave, with its parts interwoven seamlessly, pref. by special arrangements of the thread cross-over points at the fabric edges, with reciprocal weave effects formed by displacement of the weave point with each successive weft thread by one warp thread to left and right. Pref. on the inside of the cuff casing (1) is a rectangular pocket (2) in which is housed an inflatable pressure bag, and which is seamlessly interwoven with the cuff casing at the two longitudinal edges and one side edge. At the other side edge is a pocket opening (3) for introducing the bag (5) and at one of the longitudinal edges is a passage (4) for the air tube (6). The cuff has reduced mfg. costs.

Abstract: Process for improving the characteristics of non-wovens contg. thermoplastic materials, by passing them through the hip of heated calender bowls, one at least of which is embossed in a pattern is described. Any treatment with additives for modifying the characteristics of the fabric, has to be carried out in a separate operation. - Improvement comprises bonding a fabric contg. in its structure distributed thermoplastic material whilst at the same time applying substances to modify the characteristics. The fabric is brought into contact with a transfer band carrying >=1 modifying agent; the band and the fabric being subjected to the action of heat and pressure in different zones spaced some distance from each other. The fabric is thus bonded in these zones and the modifying agent is transferred to the fabric in zones corresponding to them. The modifying additive used improves >=1 of the following or endows them-; pigmenting, affinity for dyestuffs, metallic sheen, resistance to accumulation of static charges, retarded inflammability, bulky appearance, electrical conductivity, thermal conductivity, resistance to breakdown by light. The bonding the application of the additive is effected by passing the fabric and the transfer band through the nip of two cylinders, >=1 of which has a surface pattern of raised zones. The process may be carried out also by passing fabric and transfer band between an ultrasonic energy hammer and an anvil; the anvil being provided with a surface pattern of raised zones. - Woven, needled and/or  knitted fabrics are processed by point bonding in a pattern whilst simultaneously applying characteristic modifying additives.

Abstract: PURPOSE:To suppress the deviation of a phase when a fault is generated and restored and to improve the reception rate after the restoration by allowing a slave station to detect whether or not a delay is invalid, setting immediately a valid delay and allowing a master station to set a valid delay accordingly. CONSTITUTION:A slave station is provided with a means 4 displaying whether or not a delay set to a phase adjustment section 2 is valid and a means 5 requesting the transmission of a phase adjustment signal to a master station from the slave station, and the master station is provided with a means sending the phase adjustment signal with the request of the transmission of the phase adjustment signal from the slave station. Thus, the slave station detects an invalid delay to set a valid delay immediately, the master station sets the valid delay accordingly and even after a fault takes place, the phase shift is immediately suppressed.

Abstract: A communication system is provided whereby desired information can be transmitted in accordance with conditions and the application. The communication system includes a PHS terminal and a provider system that is capable of information communication with this terminal. The PHS terminal has a voice recognition section that receives voice from a microphone and recognises the received voice signal, an input device that selects the output form of the voice signal, a conversion section that converts the recognised voice signal with the selected output form, and a transceiver that transmits the converted voice signal to the provider equipment; the converted voice signal is further transferred from the provider system to another destination wireless communication terminal device. This output form includes for example "dialect", "intonation/imitated voice of a celebrity etc." or "modulation". Conversion filters convert the voice signal in accordance with these.

IPC: H01L21/60
Filed: 1978-07-06
Abstract: PURPOSE:To make possiboe many contacts and make easy switchings of contacts with a simple control circuit by forward and reverse of cam. CONSTITUTION:The rotation of a cam shaft 18 descends a tool 16 to push a line 23 against the first connecting point. The aperture of a cam 34 is detected 44 between the positions DE to generate 33 ultrasonic and connect. A reverse signal is generated 51 after a certain time from the detection. The motor 30 runs reversely to ascent a tool 16, moving XY rack toward the second connecting point. When the tool 16 reaches the position C, a reverse signal is generated through a cam 36 and a sensor 42 to stop the motor 30, and the XY rack 12 moves to the second connecting position. The completion of the rack movement starts the forward of the cam shaft 18 to be connected in the same manner. As the connecting is finished, the tool 16 ascends, the rack 12 moves, the tool 16 reaches the third connecting point to produce 33 ultrasonic through a cam 35 and a sensor 45 for connecting. At the end of connecting, the line is clamped 22 and thus ascends to be cut with the base of the tool 16. Under this structure, a control circuit is simplified and no change of cams is necessary for the change of connecting frequency.

The opacifying layers 8, 10 have greater absorption characteristics for the laser radiation than the film or substrate 12 which is substantially transparent to the selected wavelength of the laser radiation so that after ablation of the area of printed matter 8 on one surface, the radiation passes through the substrate 12 substantially unaffected to ablate the area of printed matter 10 on the opposite surface. In the resultant article, the markings or windows formed by the areas of printing removed from each surface of the substrate 12 are in register, and provide a deterrent against counterfeiting.

Abstract: An electronic digital control system monitors and controls the operation of an engine fueling system. Signals activating injection for a plurality of cylinders are transmitted through a single line to a driving circuit for a single injector solenoid valve, while signals controlling accumulator fuel pumps are transmitted to pumping control solenoids. Injection signals are controlled to vary fuel delivery rate during an injection event. A back EMF sensing circuit measures valve opening delay and the control system compensates for valve delay. Variable cylinder-specific delays in the injection solenoid output signal pulses are programmed to compensate for a varying fuel line length to each injector nozzle. At startup, the control system pulses the pumping control solenoids to begin pressurizing the accumulator before engine angular position sensors provide an accurate indication of engine angular position to allow precise timed control of the pump. Pressure variations in the high pressure accumulator are monitored by the control system in conjunction with injection events, and pump equipment failures or weaknesses are detected based on the pressure variations. In alternative embodiments of the invention, a pre-biasing current using battery voltage is provided to the injection control valve prior to the desired time of an injection event, and the current is increased at the desired time of opening. An input allows signaling the control system when a load is to be applied to cause an immediate change in fueling levels, to prepare for load increases in electrical generation and other non-motive-power applications. <IMAGE>
