IPC: G01R31/02
Filed: 1981-07-31
Abstract: PURPOSE:To reduce the test time while enabling clear separation of the abnormality in the tester itself from the abnormality in the electrical appliance by checking for a load short-circuit before the application of a test voltage. CONSTITUTION:When a test starts for each testing item, first, in order to measure the impedance of a voltage application element of an electrical appliance 2 as test object, a contact 10a is turned on to apply a voltage for checking a load short-circuit.

IPC: B22D17/30
Filed: 1980-09-02
Abstract: PURPOSE:To easily adjust the amount of molten metal to be scooped by a ladle by adjusting the stop position of a driving device which turns over or rotates the ladle. CONSTITUTION:A suitable manual handle is fitted to the head part of a screw 74, and when a pressure plate 66 is turned by advancing the screw shaft 74 to the extreme left, it is stopped in the position A. If the shaft 74 is retreated to the extreme right, the plate 66 is stopped in the position C. Hence, if the position of a strand of chain is so set that the angle of inclination of a ladle is 0 in the position A, the angle of inclination is 30 deg. in the position B and 60 deg. in the position C, the angle of inclination of the ladle can be adjusted continuously and arbitrarily within the range of the turning angles from the positions A to C. Hence, the amount of the molten metal corresponding to the volume of the product to be cast is easily adjusted by the angle of inclination of the ladle by the forward and backward adjustment of the shaft 74.

IPC: B65H3/06
Filed: 1988-05-19
Abstract: PURPOSE:To make sheet feeding accurately performable even if the insertion of each sheet by manual operation or the like is not sufficient enough by installing a freely retractable projection in a sheet feeding member. CONSTITUTION:When a start key is pushed after a sheet S1 is inserted thereinto by manual operation or the like, a paper feeding member 1 gets rotating clockwise, and each of projections 10d, 10e comes into contact with this sheet S1. If this paper feeding member 1 is rotating in a arrow C direction, the sheet S1 is fed in an arrow D direction by dint of frictional force out of these projections 10d, 10e. When the paper feeding member 1 is further rotated, since an interval between these projections 10d, 10e and a topmost sheet S0 is narrowed, these projections 10d, 10e receive pressure from sheets S in a housing 3 via the sheet S1. However, since these projections 10d, 10e and an outer layer part 10 have elasticity each, these projections 10d, 10e are sunk in cavities 12, 13 installed at both sides of the paper feeding member 1, so that the sheet S1 receives frictional force of a friction member 10c from its whole surface and conveyed in the arrow D direction.

Abstract: PURPOSE:To release the faulty state such as runaway of a central processing unit quickly by providing a reset means indexed with a specific address and resetting the central processing unit and a communication interface circuit in a terminal equipment in response to the addressing from other terminal equipment. CONSTITUTION:When a central processing unit CPU 12 and/or a communication interface I/F 14 of a terminal equipment runs away due to a cause such as noise or when the noise enters a loop between the both, the communication is disabled between both the terminal equipments and an opposite terminal equipment recognizes the production of an abnormality. Then the opposite terminal equipment sends an address B addressed to a reset bus I/F 16 to a bus 10. Then the bus I/F 16 of the terminal equipment receives the address B to generate an interrupt signal and a reset signal generating circuit 18 generates a reset signal in response to the interrupt signal. Thus, the CPU 12 and the communication bus I/F 12 are reset respectively and restored to the initial state. Thus, the abnormality is released quickly.

Abstract: PURPOSE:To improve transient responsive characteristic by operating a photocoupler in pulses. CONSTITUTION:A switching power source charges energy to a transformer 1 while a transistor(Tr) Q1, the switching element, is ON by RCC system. When the Tr Q1 is turned OFF, an electric potential to charge the current to a capacitor C across the secondary side winding terminals S1 and S2 of the transformer T1 appears and DC power is generated continuously. ln order to keep this output voltage constant, a Tr Q2 is connected to a photocoupler PC1. The constants of resistances R3 and R4 are decided so that this Tr Q2 may be turned ON when the output voltage across the secondary side winding terminals S1 and S2 is not positive. The photocoupler 1 can perform a feedback operation only in the period the Tr Q1 is ON.
