Inventor: TANAKA MASATO
IPC: G11B19/24

Abstract: A signal reproducing apparatus for reading out signals recorded along with clock signals on a recording medium (11). The relative velocity between a magnetic tape and magnetic heads mounted (13A,13B) on a rotary drum (12) is sensed by a rotary drum rotational velocity sensor (16) and the center oscillation frequency of a VCO in a clock-reproducing PLL circuit (23) of signal reproducing circuitry is changed in accordance with the sensed relative velocity for controlling the center oscillation frequency to be equal to the frequency of the clock components of the reproduced RF signals. The clock signal components may be reproduced as normally even although the frequencies of the clock components of the playback RF signals are changed. Besides, fluctuations in the relative velocity between the magnetic tape (11) and the magnetic head (13A,13B) may be tolerated to diminish the load on the velocity servo control operation as well as to reduce power consumption and expedite the operation.

Abstract: s7 A low noise frequency synthesizer 10 that uses uses frequency dividers 13, 15, at least one of which(divider 15) is incrementable and decrementable in half integer steps, and analog gain compensation in a phase/frequency detector 17 to achieve lower noise, lower spurious levels and faster switching speed than traditional methods of frequency synthesis. The key features of the present invention are its half integer dividers 13, 15 and the ability to adjust the phase detector gain to compensate the loop for varying divide numbers. The synthesizer 10 comprises two dividers 13, 15 that provide two reference frequency signals that are a function of an input signal and an output signal of the synthesizer 10. A voltage controlled oscillator (VCO) 18 provides the output signal (f o ) of the frequency synthesizer 10. A phase/frequency detector 17 compares the reference frequency signals and provides a phase error output signal that drives the VCO 18. A digital controller, comprising a PROM 11 and a digital to analog converter 12, adjusts the gain of the phase detector 17 to compensate for varying divide numbers, and selects the divide numbers. The synthesizer 10 has lower phase noise, lower spurious levels and faster frequency channel switching. To generate a frequency step of a given size, the divide number is half the step size. With a divide number of half the step size, the noise contribution from the divider is reduced by that much. The phase margin is improved with a corresponding reduction in loop peaking in the noise spectrum. A missile radar system employing the present synthesizer is also disclosed.

Abstract: The dismantleable agitator is made up of a drive shaft (1) and an agitation rotor (2) separable when stopped. The self-holding taper between the end (8) of the shaft and the hub (6) of the rotor (2) is of the inverted-cone conical type. The coupling and the separation are made possible by virtue of the alternation of shaft-hub release surfaces (10, 11 and 12) and (22, 23 and 24) which are set back and a number of male bearing surfaces (13, 14 and 15) projecting on the shaft and of female bearing surfaces (19, 20 and 21) which are opposite and of recesses (22, 23 and 24) on the hub coming into locking contact one over the other after the movements of insertion, of rotation and of lift-off during the assembling. A safety edge (25) introduced into one of the recesses after assembling provides an additional locking safety if necessary. <IMAGE>

Abstract: A phase-shifting mask consisting of phase shifting rim surrounding every pattern. A quartz substrate (10) is coated with a phase shifter material (11) which has been patterned. In some places on top of the phase shifter material (11), is a layer of chrome (12). All openings down to the quartz (10) are surrounded by a rim (border) of phase shifter material (11) extending beyond the chrome layer (12), but the rims reverse phase at every other opening, as do the main patterns. The phases need not be reversed only when the neighboring openings are sufficiently far apart so that the diffraction patterns from them do not interfere with each other. In the attached drawing, all except two openings have the regular 180° phase shifted rims around them. In the second and fourth bars (14, 16), the rims (so-called reversed rims) are now at 0° while the inside of the openings are shifted 180° which is just opposite to the normal rim shifts everywhere else. The 0° and 180° areas defined by a straightforward rim phase-shifting mask are reversed alternately for closely packed patterns. This reversal can take the form of 0° to 180° and 180° to 0° as well as the form of 0° to 180° and 0° to -180°. For small opaque lines, the rim phase shifter may become the only picture element, leaving no mask absorber pattern inside the rim. Individual or uniform pattern sizing can be used to ensure a large common exposure-defocus window. Various fabrication techniques requiring or not requiring a second aligned exposure during mask fabrication, combining with several different forms of mask substrate are also described.

Abstract: The optoelectronic finger-operated keyboard to be used in industrial measuring instruments is designed with respect to an optimum signal/noise ratio and the least possible drop in intensity of the infrared light transmitters during the operating time of the measuring instrument. The keys for generating in each case one associated useful pre-operation signal (n1, n2, n3) have for this purpose an infrared-transparent cover (1), an infrared light transmitter (3) which is arranged on the inside (12) of the cover for each key and radiates virtually vertically with respect to the cover and tightly focused, an infrared light receiver (4) which is arranged adjacently to the transmitter and separated therefrom by an infrared-opaque shield (5) and aligned towards the cover, which receiver is located within the main radiating area of the radiated infrared scattered from a finger (2) but outside the infrared reflected from the outside and/or inside of the cover. An operating circuit (8) comprises a separate control and detection circuit (15, 25, 35) for each key, which, for feeding the light transmitter (13, 23, 33), generates current control pulses (si1, si2, si3) with a mark/space ratio of less than 1:1, and a common interrogating circuit (18) for all keys, which activates a current switch (19) connecting all control and detection circuits (15, 25, 35) to one terminal (SN) of an operating voltage source. <IMAGE>
