Patent EP-0029197-A1 (EP)
Inventor: BOECKELER DIETER ING GRAD
IPC: G05D23/19
Filed: 1980-11-10
Abstract: This control is effected in dependence on a selectably predeterminable flow rate of the medium for adjusting a required temperature, comprising an hydraulic/electrical transducer detecting the flow rate and an (electrically) following pulse transmitter, the generated pulses of which are processed to form electrical control commands for the control of the heating capacity, and consists in that the pulse transmitter generates a signal with a period duration corresponding to the flow rate, by means of which, as input signal, a first monostable flip flop of a signal analyser is driven which generates a rectangular pulse, in each case beginning with a rear edge of the input signal, with fixed short pulse duration by means of which a second and a third, in each case retriggerable monostable flip flop are triggered which have reset times of different lengths and in each case, again beginning at the rear edge of the rectangular pulse, generate rectangular signals having the corresponding signal duration which are separately supplied to the two electronic memories of the dual memory via the inputs and are stored for the duration of one period by the front edge of the rectangular pulse whilst a fourth monostable flip flop of the pulse signal analyser is triggered by the signal of the flip flop having the longer reset time with one period duration, which fourth stage generates a short rectangular pulse beginning with the rear edge of the signal, which is supplied to a common reset input of the electronic memory, and that the memories generate output signals which, each by itself, are converted into electric control commands by amplifiers. <IMAGE>

Inventor: IKEGUCHI SHIGEHIKO
IPC: H03J1/00
Filed: 1980-10-15
Abstract: A voltage controlled oscillator (26) which serves as the local oscillator of a tuner, is controlled by a phase locked loop (5) and an automatic frequency control loop (3), both of which are operable to provide a control voltage to the voltage controlled oscillator (26). An analog switch (22) is controlled in such a manner that the phase locked loop (5) provides the control voltage for the voltage controlled oscillator (26) when a station is being selected, and the automatic frequency control loop (3) provides the control voltage when the tuner is receiving a desired broadcasting wave. 
     The automatic frequency control loop (3) includes a frequency discriminator (10). a window comparator (18) and a charge pump (20). The phase locked loop (5) includes frequency dividing means (28. 30) a phase comparator (32) and a charge pump (36). The outputs from the two charge pumps (20, 36) are applied through the analog switch (22) to a common low-pass filter (24) the output of which is applied to the voltage controlled oscillator (26) as the control voltage. The state of the tuner is detected in response to the output of an intermediate frequency amplifier (8) and a signal indicating whether the phase locked loop is in a locked state.

Inventor: FANG FRANK FU
IPC: H01L29/80
Filed: 1981-02-25
Abstract: A semiconductor inversion layer transistor which is compatible with semiconductor fabrication technology, and an integrated circuit which incorporates a plurality of such transistors. In one embodiment of the transistor, a P type indium arsenide base and a P type gallium antimonide emitter are used while the collector can be made of either P type gallium antimonide or N type indium arsenide. By the nature of the band alignment at the interface, the indium arsenide base has its Fermi level pinned in the conduction band at the base-emitter junction and an assymmetrically conducting charge barrier which is formed at this junction is preferential to injection of carriers flowing from the emitter to the base rather than vice versa. When the base-emitter junction is forward biased the electrons at the junction are projected across the base with minimal hole injection from base to emitter, thus providing a high gain transistor having excellent high frequency characteristics.
