Patent EP-0361336-A2 (EP)
Inventor: NOKUBO SEIJI C O ITAMI WORKS O
IPC: B60T8/40
Filed: 1989-09-22
Abstract: A flow control valve (103) for use in an antilock control device including a housing (31) having inlet (31a) and outlet ports (31b) communicating with a pressure source and a wheel brake, respectively, and a spool (32) slidably mounted in the housing and formed with a channel including an orifice. When the spool is in a first position, a large-flow passage is formed between the inlet and outlet port. When in another position, a restricted-flow passage is formed between the inlet and outlet ports through the orifice while the large-­flow passage is closed. A piston is mounted in the housing on top of the spool. Every time the brake is applied, the piston is adapted to move up and down, thus allowing the spool to slide in the same direction to the first position. 
     In place of the piston, a sleeve may be disposed between the inner periphery of the housing and the outer periphery of the spool so as to be slidable relative to both the housing and the spool. Every time the brake is applied, the sleeve is adapted to slide against the bias of a spring. 
     In either arrangement, a relative movement takes place between the spool and the housing or the sleeve every time the brake is applied. This will prevent the spool from getting stuck between the first and second positions.

Abstract: For an optical receiver with trans-impedance amplifier (TIV), it is known for the purpose of widening the dynamic range, to operate, by means of a direct-current-limiting element in the direct-current circuit of the photodiode (PD), this photodiode as an alternating- voltage source in the case of high input levels and to convert by means of an alternating-current circuit the alternating voltage into an alternating current as input current of the trans-impedance amplifier (TIV) which is within the permissible range. According to the invention, the alternating-current circuit (Cs, Rs) leads from the connection (2), which is not connected to the trans-impedance amplifier input, of the photodiode (PD) to the output (Ua) of the trans-impedance amplifier, which results in an increase in the dynamic range. The current-limiting element is preferably a transistor circuit (RE, T) connected as constant-current source. …<IMAGE>…

Abstract: A fail-safe thermostat for vehicular cooling systems is positioned in a junction (13) leading to an internal coolant passageway, a radiator passageway and a bypass passageway (19). An open housing seated in the junction supports a fixed central rod (44) extending into the wax filled interior of a movable cylindrical member (36) which controls the position of the interior segment (32) of a main valve (30). Expansion of the wax forces the cylindrical mem­ber in a first direction against a compression spring (62). Fusible alloy is disposed in the coupling between the cylindrical member and the main valve, and melts at a specific temperature range in excess of the normal range. When this occurs the coupling is released in such a way that the spring forces the valve member to a second limit position opposite to the direction of expansion. A bypass closure member (64) at one end of the cylindrical member may be used to close the bypass passageway concurrently with increased temperature.

Abstract: The invention relates to a method of setting the voltage in a well-defined manner in semiconductor devices which are resistant to breakover firing and have a well-defined breakover firing voltage. In this method, at a position provided for the purpose, a doping region 2 is formed underneath with the aid of a depression VP or VPS in the surface in such a way that it follows the depression contour in the region underneath the depression and the doping boundary surface DP or DPS is formed. If the shape of the depression is fixed, the breakover firing voltage depends only on the doping profile, which can be well controlled, and it can therefore be set in a well-defined and reproducible manner. According to the invention, a fixed, for example pyramidal or truncated-pyramid depression can readily be produced through the choice of wafer material, the shape and the orientation of the mask opening, and by using anisotropic etching. If doping is then carried out from the side of the depression, a doping region having a well-defined shape and corresponding to the depression is produced.

Abstract: A linear array of light emitting diodes (CR1-CR7) direct a diffuse beam of radiation across the path of seeds dropping down a seed chute and onto two detectors (46, 48) connected in parallel, so that every seed produces a substantially equal area pulse in the output signal from the photo detectors. The signal is amplified (50) and applied to an analog to digital converter (52) producing digital samples at a high rate for processing by a microprocessor (54). The sensor value is subtracted from an offset value corresponding to the sensor signal when no seed is present and the difference signal is repeatedly added to an area signal. The offset value is adjusted from time to time to prevent the difference signal staying persistently negative or persistently positive. Whenever the area signal reaches a threshold value the passage of a seed is indicated and the area signal is decremented by an estimated, area value corresponding to one seed. This estimated area value is adjusted from time to time so as to avoid long term drift in the area value, thereby maintaining the estimated area value accurately representative.

Abstract: An ultrasound system (100) for investigating a subject (91) comprises a probe (102), a signal processing module (104), and an interconnecting cable (106). The probe includes an annular phased array transducer (120) defining multiple signal processing channels Ch1-CH12. The signal processing module includes a controller (106), a transmitter (110), a receiver (112), delay circuitry (114), and a video section (116). Within the delay circuitry, each signal processing channel includes an inphase branch and a quadrature branch. Each branch includes an analog-to digital converter (ADC 412, 422) and a delay first-in-first-out (FIFO 416, 426) memory. Dynamically variable delays are implemented by varying the sampling and FIFO input rates relative to constant FIFO output rates. The variable clock rates are derived by switching between phase-staggered replicas of a master clock MCLK, which has a rate at the nominal center frequency of the ultrasound signal prior to sampling. The timing circuit (700) used to derive the variable clock rate signal uses a focus FIFO (706) to serve as a timing buffer between the variable clock rate signal and the master clock signal. Inphase data streams from each channel are combined in a pipelined adder (314); quadrature data streams are similarly combined. An interpolator (318) permits accurate combinations of the summed inphase and quadrature data streams. The resulting combination is directed to the video section for output. Advantages of the disclosed system include low signal processing, memory and data rate requirements, resulting in a more reliable and economical high-performance ultrasound system.

Abstract: Ink ribbon cartridges for typewriters or similar office machines are subject to various design requirements and are, above all, to be easily exchangeable using one hand. For reasons of environmental pollution, the ink ribbon cartridges (1) have a hinged lid (5) for changing the ink ribbon spools (27, 53). In this case, in known ink ribbon cartridges, the receiving spool (27) mounted on a swivel lever (21) has to be disengaged from a driven pin roller (29). The swivelling of the swivel lever (21) from the engagement position into the position of rest takes place via a manual setting lever (13), in which case the force of a tension spring (57) linked to the swivel lever (21) has to be overcome. The winding of the ink ribbon (47) onto the receiving spool (27) and the swivelling of the swivel lever (21) are facilitated according to the invention by a deflection (65) on the swivel lever (21) when a long tension spring (57) is used, as a result of which a spring with a slightly rising spring characteristic can be used. <IMAGE>
