Patent ES-361709-A1 (ES)
Title: Data transmission terminal
IPC: H04L25/48
Filed: 1968-12-20
Abstract: Binary data is translated to ternary low disparity code prior to transmission. Each 4-bit data group is converted to a corresponding zero or positive disparity 3-digit ternary group. The cumulative disparity of the transmitted ternary groups is determined and when this is positive the next positive disparity group is inverted prior to transmission. At the receiver the data is reconverted to binary form, the sense of the disparity being of no significance. Transmitter, Fig. 2 and Fig. 3 (not shown).- Serial binary data is staticized in shift register 200, each parallel 4-bit group passing via store 201 to translator 203 comprising gates. Parallel 3-digit ternary data is serialized at 204 and passes via inverter 205 to the transmitter output and also to unit 208 which includes an integrator which records the total disparity. If the disparity is positive the next positive disparity ternary group is inverted by enabling inverter 205. The inverter and unit 208 are inhibited whenever a zero disparity group is generated by the translator. The various units are controlled by timing pulses derived from a bit-rate clock source feeding counter divider 202 whose output feeds tuned multiplier 207. In a modification, Fig. 7 (not shown), the translator outputs 4-digit groups, one digit being zero, so that the serializer (704) can operate at the input bit rate. The inverter then feeds a unit which changes the digit rate to threequarters the bit rate prior to transmission. Receiver, Fig. 5 and Fig. 6 (not shown).-The ternary data is converted to parallel form at 500 and passed to translator 501 which converts the data to the corresponding 4-bit group. The binary data is stored at 503, serialized at 504, and passed to the receiver output. Digit rate clock pulses control the circuitry via counter divider 502 and tuned multiplier 505. Synchronizing.-During transmission, the ternary group 000 occurs once in each 1000 groups. When a group 000 is detected in the input staticizer 500 a monostable unit is triggered and generates a signal having a 1:1 mark: space ratio if the rate of occurrence of the groups is 1 in 1000. The monostable feeds an integrator, and if that rate of occurrence is exceeded the integrator output causes a pulse to be generated which blanks one of the digitrate clock pulses being fed to the staticizer 500 and to divider 502, thereby adjusting the phase. Multiplexing, Fig. 9 (not shown).-By translating from binary to ternary code a 24-channel binary PCM input occupies only part of the bandwidth of the transmission channel that would be needed to transmit the PCM in binary form. The unused part of the channel may therefore be used for additional data or speech channels.

Patent ES-444479-A1 (ES)
Title: Automatic machine tool including a monitoring system
IPC: G01H1/00
Filed: 1976-01-20
Abstract: An automatic punch press and monitoring system. The monitoring system includes a piezoelectric accelerometer mounted within the stationary die shoe of the punch press, and electronic circuitry including a variable gain amplifier, a detector, an integrator, and a comparator. The monitoring system is manually placed in a "LEARN" mode whereupon the signal produced by the accelerometer during normal operation of the punch press is amplified, detected, and integrated over the time period of one stroke to produce a test function. The gain of the amplifier is automatically adjusted during successive normal strokes of the punch press until the test function is equal to an arbitrary set point, thereby establishing a reference function. The monitoring system is then automatically placed in an "AUTO CONTROL" mode whereupon on each succeeding stroke, with the gain of the amplifier fixed, the test function produced is compared with the reference function. If the test function is above a first high limit level corresponding to a percentage of the reference function and below a second high limit level corresponding to a second percentage of the reference function a check alarm is activated. If the test function is above the second high limit level or below a low limit level corresponding to a third percentage of the reference function the punch press is shut down.

Title: Method of high current ion implantation and charge reduction by simultaneous kerf implant
IPC: H01L21/265
Filed: 1978-01-28
Abstract: A method of ion implantation is provided which is particularly applicable to the fabrication of integrated circuits with high current ion implantation apparatus utilizing ion beams having currents of at least 0.5 ma. The method avoids excessive charge buildup on semiconductor wafer surfaces which may destroy the surface electrical insulation, thereby rendering the integrated circuit ineffective. The method involves forming in a layer of electrically insulative material over the wafer, a plurality of openings through the insulative layer in the various chip areas to expose the semiconductor wafer surfaces which are to be ion implanted with conductivity-determining impurities, and in addition, forming openings through the insulative layer over the kerf area between wafer chips to expose wafer kerf adjacent to the chip openings. The total area exposed in the wafer kerf must be greater than the total area exposed in said chip wafer openings. Then, a beam of ions having sufficient energy to implant ions in the exposed wafer in said chip area and kerf openings is directed at the wafer. The presence of the kerf openings avoids the problem of charge buildup. Then, the kerf area is removed by conventional dicing to separate the wafer into a plurality of chips.

Patent ES-475798-A1 (ES)
Title: Rotary-anode X-ray tube
IPC: F16C33/10
Filed: 1978-12-07
Abstract: A rotary-anode X-ray tube, comprising a rotary anode which is journalled in a vacuum-tight housing by means of at least one sleeve bearing whose mutually co-operating bearing surfaces are made of W or Mo or of an alloy of W and Mo. The bearing is lubricated by Ga or a Ga alloy having a melting point below 25 DEG C. The Ga or Ga alloy lubricant is in molecular wetting contact with the bearing surfaces so that the bearing surfaces are completely separated from each other in the loaded condition. During standstill, as well as during rotation, the lubricant is not forced out of the bearing, so that the bearing surfaces cannot become fused. The wear and the bearing noise are therefore extremely low. The desired, thorough wetting is obtained by making the bearing surfaces, as well as the Ga alloy, oxide-free before they are brought into contact with each other.

There is also a reference oscillator (7) which acts on the phase discriminator via a fixed divider (5) and a phase modulator (6). The divided-down reference signal (02) thus derived from the reference oscillator is modulated by the modulation signal (U1). This enables relatively large phase or frequency deviations to be attained.
Patent ES-481438-A1 (ES)
Title: Electric starting system for diesel cycle internal combustion engines
IPC: F02P19/02
Filed: 1979-06-11
Abstract: An electrical starting system for a Diesel engine has a manual selector switch which is moved momentarily to a preheating position to energize a relay which is then held energized by a relay switch from a battery D.C. source until the engine combustion chambers have been preheated sufficiently by preheating plugs to enable starting to be effected, indicated by the switching off of an indicator lamp. Starting can then be effected by the selector switch. If the preheating of the engine is incomplete the indicator lamp remains lit. A thermometric cut-out switch inhibits the preheating relay when the engine reaches a threshold temperature, avoiding wasteful operation of the preheating plugs with a hot engine.
