Title: Cover with automatic opening mechanism for press
Inventor: KATO AKIRA
IPC: B30B15/00
Filed: 1993-04-28
Abstract: PURPOSE:To provide a cover with automatic opening mechanism for press which is automatically opened utilising upward moving of a movable part and which is provided by a cheap initial investment since the cover is simple in construction and compact in size. CONSTITUTION:A lever 25 for the cover is movable around a supporting shaft 31. The cover 20 is supported on one side of the lever 25 with a pin 32 and a weight 40 is supported on another side of the lever 25 with a pin 33. A hook 13 is hung on a pawl 34 fitted on the lever 25 so that the cover 20 is automatically lifted when the movable part 12 is moved upward. When the movable part 12 is covered by the cover 20 which is located below, the cover 20 is held in a closed state since the centroid is on the cover 20 side and when the cover 20 is lifted in an open state, the cover 20 is held in an open state since the centroid is on the weight 40 side.

Title: Continuity inspecting apparatus
Inventor: UKITA AKIO
IPC: G01R31/302
Filed: 1989-05-17
Abstract: PURPOSE:To perform inspection in a mechanical non-contact state without damaging a terminal part by detecting the waveform of a current by the irradiation with ultraviolet laser beam. CONSTITUTION:The ultraviolet laser beam 9 from a laser generating apparatus 12 is converged by a lens 11 and subsequently turned ON/OFF by a shutter 10 to become pulse like beam which is, in turn, applied to the terminal part of a substrate 3 through the laser beam introducing port 13 provided to a vacuum tank 1. Electrons are discharged by external photoelectric effect to be caught by an electrode 15 and, therefore, the electron quantity of a circuit pattern is reduced and potential becomes high. Therefore, the electrons once discharged are brought back to return to the circuit pattern and the return rate thereof increases are potential becomes high and, at last, the reduction of electron quantity is gone and potential becomes unchangeable. The potential at this time is set to V2 and the potential of the circuit pattern before the irradiation with the beam 9 is set to V1 and, by detecting and comparing the waveform of the current of the electrode 15 when potential changes from V1 to V2, the inferiority of continuity can be judged in a mechanical non-contact state.

Abstract: PURPOSE:To discriminate easily an input position on an input form by carrying out the conversion of coordinates after detecting the positions of plural magnetic bodies buried into the input paper on a tablet and therefore omitting a troublesome job to set the input paper at a designated position. CONSTITUTION:An input paper 11 is put on a tablet 1 and the handwritten characters into an optional character input frame 12 by mans of an input pen 24. Thus the input coordinate value of the pen 24 to be applied to an XY coordinate system of the tablet 1 is detected and sent to a coordinate value conversion processing part 2. The part 2 detects the coordinate positions of magnetic bodies 9 and 10 of the form 11 and converts the input coordinate value into the coordinate value of the coordinate system presumed on the frame 12 with the body 9 defined as an original point on the basis of both coordinate positions. Then the coordinate value thus obtained is stored in a memory 7. When the input equivalent to a character is through, a feature extracting part 4 extracts the features of the input characters stored in the memory 7. These features are recognized by a character recognizing part and sent to the memory 7 and also displayed on a CRT6.

Abstract: PURPOSE:To enable a measurement utilizing a Coriolis force with a high S/N ratio to be performed by making a conduit plane perpendicular to a piping and increase the rigidity of the conduit in a lateral direction which tends to be affected by the oscillation of the piping. CONSTITUTION:A conduit 2 is formed to a loop-shaped configuration that surrounds a fluid pipe 1 on the same plane. Inlet and outlet openings 21 and 22, respectively, are symmetrically arranged with respect to a first axis XX'. A ring 35 to which a magnet 3 excited by a coil 4 is mounted is fixedly mounted on the second axis YY' of the loop. Since, when a fluid enters the inlet opening 21, flows in the conduit 2 following the loop and flows out from the outlet opening 22, the conduit 2 is oscillated to be rotationally displaced about the second axis YY', a mass flow rate is obtained by measuring a rotational displacement due to a Coriolis force by detectors arranged in predetermined positions (m) and (n) of the conduit 2 as a time delay produced when a reference plane, such as the stationary plane of the loop of the conduit 2, is passed.

Abstract: PURPOSE:To measure many items by one instrument simultaneously by sampling the phase currents of two phases of an electric power system and the voltage between two wires relating to them and performing specific arithmetic on the basis of digital values of the currents and voltage. CONSTITUTION:The voltage and current values of the electric power system are supplied to sample holding circuits 11 and 12 through a voltage detector PT and a current detector CT and the voltage and current value are sampled at every interval of time corresponding to, for example, an electric angle of 30 deg. and held up to a next sampling period. Those values are stored in a memory 3 through an A/D converter 3 while switched by a multiplexer 2. Then, an arithmetic processor 5 performs the specific arithmetic on the basis of stored data in the memory 4 to obtain three-phase active power and three-phase reactive power. Those values are sampled at the intervals of one second to find plus and minus three-phase active electric energy and positive and negative three-phase reactive electric energy. Thus, the various values of electric power are measured by the same instrument simultaneously, so the cost is reduced.
