Patent EP-0315229-A2 (EP)
Inventor: CHEN TEH-YI JAMES
IPC: H01L29/78
Filed: 1988-09-28
Abstract: Gate sidewall spacers are created by a two-step procedure in fabricating a field-effect transistor using a protective material such as silicon nitride to prevent gate-electrode oxidation. In the first step, a layer (32) of insulating material is conformally deposited and then substantially removed except for small spacer portions (34) adjoining the sidewalls of a doped non-monocrystalline semiconductor layer (20A) destined to become the gate electrode (36). The second step consists of performing an oxidizing heat treatment to increase the thickness of the spacer portions. No significant gate dielectric encroachment occurs. Also, the spacers achieve a profile that substantially avoids electrical shorts.

Abstract: A current control circuit is provided for a stigmator lens of an electron or ion beam machine. The stigmator lens consists of two magnetic quadrupole lenses, each of which has two pairs of coils. Current monitoring resistors R10,R11,R12 and R13 are connected in series with the individual coils L1,L2,L3 and L4 of the quadrupole and a resistor R3 is connected to monitor the sum of currents in the pairs of coils. Voltage signals from the resistors are used to close feedback loops which drive currents into the individual coils so that the sum of currents in a pair of coils is held constant at a value set by an adjustable astigmatism control and so that the ratio of the currents in a pair of coils is held constant at a value set by an adjustable beam centering control. Coil currents are stabilised in spite of coil resistance changes due to Joule heating by the currents. Computer control of astigmatism and centering is facilitated since only signal voltages are required as inputs to the circuit.

Abstract: A signal receiver which is capable of receiving and demodulating a satellite broadcasting signal which is an FM signal and a terrestrial broadcasting signal which is an AM signal is disclosed. FM and AM signals are frequency-converted into signals having frequencies in a same intermediate frequency band by making common use of a radio frequency amplifier, a mixer, a local oscillator and an intermediate frequency filter. At the time of reception of an FM signal, the FM signal is demodulated in a phase-locked loop circuit, and a local oscillator is subjected to frequency modulation by a part of the demodulated signal, thereby constituting an FM negative feedback loop, and thus narrowing the occupied bandwidth of the FM signal. At the time of reception of an AM signal, the phase-locked loop circuit is used to regenerate a carrier, and the output signal of the phase-locked loop circuit is input to a multiplier to effect synchronous detection of the input signal. At this time, the FM negative feedback to the local oscillator is utilized to effect automatic frequency control, thereby achieving stabilization of the synchronous detection.

Abstract: An apparatus for controlling the output of a switching amplifier (38) includes a signal dividing circuit (14) which generates a delayed replica (S1) of the carrier signal and a doubled signal (S2) having twice the carrier frequency. The doubled signal is effective for establish­ing a second time delayed signal relative to the first time delayed signal (S1A). The first and second time delayed signals are logically operated on so that a three state output representing the carrier signal is attained. A summing amplifier (26) utilizes the two time delayed signals to generate this three state output whereby if the two time delayed signals are out-of-phase, a zero voltage is connected to the drive portion (40, 42) of the switching amplifier thereby limiting the output of the switching amplifier.

Abstract: A continuously variable transmission has a drive pulley having a shiftable disc, a driven pulley having a shiftable disc, a belt engaged with both pulleys, a spool type transmission ratio control valve (90) having a plunger (93) slidably mounted in the valve body, and a spring (94) provided between the plunger (93) and the spool (92). A selector device is provided for selecting the engine speed driving range (110). The selector device has an actuator (120) responsive to the selection of a high engine speed driving range for shifting the plunger (93) so as to increase the load on the spring (94), and a correcting lever (128) for controlling the operation of the actuator (120) in accordance with the transmission ratio. The correcting lever has a shape for providing a transmission ratio changing characteristic which is such that the transmission ratio changes with small changes of the engine speed in an extremely low vehicle speed range, but changes with larger change of the engine speed in low and middle vehicle speed ranges above the extremely low vehicle speed range. 
     The actual transmission ratio is fed back to the system by the relative position of the shiftable disc (36b) via a sensor shoe (85) acting on a line pressure valve spool (82) and the correcting lever (128).

Abstract: Before a measurement phase begins, the null measurement value of each individual sensor of a pressure distribution transducer is determined. The max. value of the null values is fed to a comparator as a reference value. During a measurement phase the measurement values are permantly read into a semiconducting memory. Measurement values acquired during the measurement phase are continuously compared with the max. null measurement value. If at least one measurement value exceeds the max. null measurement value, only a limited quantity of pressure measurement data is stored in the memory. The quantity stored is less than the memory capacity.

Abstract: Alarm units (13a ∼ 13e) for generating alarm sounds having, e.g., different tone are arranged in the respec­tive automatic chemical analysis apparatuses (12a ∼ 12e) in an automatic chemical analysis system. When a change occurs in an apparatus, a detection signal is output from a predetermined detector (18-1; 18-2; ...; 18-n) which detects the change. A control section (19) reads out sound data from a RAM (30) on the basis of the detection signal, and outputs the readout sound data to a PSG (programmable sound generator) (20). The PSG (20) generates a predetermined alarm sound from a speaker (17) on the basis of the readout sound data. An opera­tor can easily distinguish an apparatus which is gener­ating the alarm sound and can quickly respond to the change. Since the alarm units generate different alarm sounds corresponding to the change levels of the apparatus, the load of the operator can be reduced.

Abstract: An instruction decoder (20) generates implied specifiers for certain predefined instructions, and an operand processing unit (21) preprocesses most of the implied specifiers in the same fashion as express operand specifiers. For instructions having an implied autoincrement or autodecrement of the stack pointer, an implied read or write access type is assigned to the instruction and the decode logic is configured accordingly. Conflicts created by the implied specifiers are handled in the same manner as conflicts for express specifiers. Moreover, by using the same data paths for both the implied specifiers and the express specifiers, and by inserting queues between the instruction unit and the execution unit, performance gains are realised for instructions having implied specifiers as well as just express specifiers.
