Title: Detecting a railroad vehicle on a railroad track
IPC: B61L1/18
Filed: 1976-01-08
Abstract: 1531982 Continuous rail track circuit GENERAL SIGNAL CORP 8 Jan 1976 [9 Jan 1975] 689/76 Heading B7N In a continuous rail A.C. track circuit defined by shorting links 103, 104 the ends of the circuit are fed in antiphase via coils 105, 106 coupled to oscillator 107 operating at e.g. 5 kHz the centre of the circuit is switched between open and short circuit by biasing a diode bridge 114 from a modulator 116 operating at approx. 100 hertz and receiver coils 110, 111 supply an output to control track relay 131 via AND gates 121-124. In the absence of a train the output from each of the receive coils X (110) and Y (111) is high when the centre of the circuit is short circuited and low (due to antiphase feed) when the centre is open circuited. The output of coil X controls gates 121, 122 such that gate 121 provides an output when coil X supplies a low signal and gate 122 provides an output when coil X supplies a high signal. Gates 123 and 124 are controlled by the outputs of gates 121, 122 and coil Y such that gate 123 provides an output when both coils X and Y supply low signals and gate 124 provides an output when both coils X and Y supply a high signal. Units 126, 127 supplied from gates 123, 124 each provide outputs of + 6V when they receive an input and - 6V when the input is absent and thus alternately saturate in opposite direction at the modulation rate a transformer 128, 129 having a square hysteresis loop. The transformer output operates relay 131. When a train enters the track circuit, the output of the receiver coil at the entry end remains high so that there is no change in the direction of saturation of the transformer and the relay drops away. In a second arrangement for a track circuit with points each of the entry points is associated with a section of the track D, E and F and is fed from the oscillator source, the supply to the entry point associated with section D, which has a length of track in common with section E and a further length in common with section F, is fed in antiphase to that of the other sections and its supply is switched on/off at the modulator rate and the two receive coils are positioned respectively to monitor the current in the two common sections of the track.

Abstract: 318,218. Universal Winding Co., (Assignees of Burton, H. F.). Aug. 31, 1928. [Convention date]. Creel arrangements.-In creels of the magazine type as described in Specification 293,439, [Class 142 (iv), Woven fabrics &c.], ballooning of the yarn drawn from stationary cops &c. is restricted by passage through holes in a frame, the holes being connected by slots. Yarn y from a cop Y or Y' passes through a hole 26 in the frame 20, over a wire 35, through a guide 16, between tension discs 15, around a pin 12, and through a guide 17. The wire 35 acts as a support and assists in restricting ballooning. The cop spindles 8 are carried on arms 7 swivelled on upright rods 3, each having a projection 9 to engage with an internal recess x<1> in the top tube X. A slotted plate 30 on the frame is bolted to an arm 21 clamped to a creel upright 4 by a setscrew 23, whereby the holes 26 may be aligned with the axes of the cops, which are directed downwardly towards the guide 16. The yarn end y<1> carried in a recess in the cop tube is knotted or spliced to the commencement end y<2> of the adjacent cop, so that, when a cop is emptied, the yarn traverses the slot 27, allowing the empty spindle to be swivelled back, another cop mounted, and its end knotted up.

Abstract: The invention relates to a glass vessel (1) for containing hot beverages, the glass container (2) of which having, at its upper end (23), an opening (28) bounded by a rim (34). Fixed to the rim (34) is a plastic ring (30) which is equipped with a pouring spout (39) and is composed of a first (31), second (32) and third (33) ring. The third ring (33) bounds the opening (28) from outside. The second ring (32) is supported from above against the rim (34) of the glass container (2). The first ring (31) engages with the aid of resilient fastening elements (35) into the opening (28) of the glass container (2) from above. A constriction (26), running around annularly, is formed on the glass container (2) below the rim (34). The fastening elements (35) engage resiliently behind the constriction (26) from above and lie flush against the inner wall (27) in the region of the constriction (26). Both the third ring (33) and the first ring (31) run at a distance from the opening (28). As a result, even in the case of frequent temperature action over a long time a firm seat of the plastic ring (30) on the glass container (2) is achieved. <IMAGE>

Title: Health checking system for computer system
Inventor: MAEDA KAZUNOBU
IPC: G06F11/22
Filed: 1986-01-08
Abstract: PURPOSE:To detect early a no-communication state by deciding a trouble occurring at the reception side in such a case where the transmission side transmits repetitively the start signals at a fixed time interval and in a fixed frequency after a data link is broken and then no answer is received from the reception side. CONSTITUTION:Both processors 1 and 2 are connected with each other by a public circuit containing an exchange network 5 via communication controllers 3 and 4. The processor 1 sends a start signal to the processor 2 and the processor 2 sends an answer signal back to the processor 1. An end signal is transmitted from the processor 2 after the end of a data link and the connection of the public circuit is cut off. The processor 1 transmits new start signals to the processor 2 at a fixed interval and in a fixed frequency in case the processor 1 receives no communication end signal nor the start signal of the next signal within a fixed period of time after the end of the data link. Then the processor 1 decides a trouble of the processor 2 and cuts off the connection of the public circuit if the answer signal is not received yet. In such a way the useless connection of the public circuit is prevented, therefore, the using cost of the public circuit is saved.

Title: Semiconductor strain transducer
Inventor: AKAHA RIYOUZOU
IPC: H01L29/84
Filed: 1979-01-10
Abstract: PURPOSE: To relieve tensile stress acting on a semiconductor substrate by constructing an insulation protecting film in two layers: SiO 2  and Si 3 N 4 .  
     CONSTITUTION: On one main surface of a semiconductor substrate a strain sensitive resistance region is provided, by insulating electrically from the substrate, via an insulation protecting film formed between the region and the substrate. Thermal expansion coefficient of Si 3 N 4  film produced in the gaseous phase is almost equal to that of Si, but there exists residual stress in the film. It is known, therefore, that compressive stress acts on Si in contrast to the Si 3 N 4  film. Accordingly, if films of SiO 2  and Si 3 N 4  are laminated tensile stress between films of Si and SiO 2  can be relieved and initial strain of a strain gauge can be eliminated. Moreover, the film of Si 3 N 4  is superior to the film of SiO 2  in the capability of preventing alkali-ion or humidity, thus an excellent protecting film is obtained. Layers composed in the reverse order would be unsuitable, because of the dislocation of Si.

Title: Motor driving control circuit

IPC: G05D3/12
Filed: 1987-01-06
Abstract: PURPOSE:To improve the control accuracy by generating a compensation signal used to compensate the effect of gravity based on the rising speed of a mobile body and a descending speed. CONSTITUTION:The titled system consists of a motor 1 driving vertically a mobile body via an elevating/lowering mechanism, a speed detecting means 2 detecting the rising and descending speed of the mobile body, a compensation signal generating section 3 generating the compensation signal used to compensate the difference between the rising and descending speed due to the effect of gravity in the position control of the mobile body based on the detected speed, and a torque control section 4 controlling the torque of the motor 1 based on the supplied position control signal and the generated compensation signal. Thus, the motor is driven by a torque to minimize the difference between the rising speed and the descending speed of the mobile body in the motor driving control circuit, resulting that the effect of gravity in case of the positioning control of the mobile body is minimized to improve the positioning accuracy.
