Title: Refresh signal switching circuit
Inventor: HIRASAWA TSUTOMU
IPC: G11C11/406
Filed: 1988-08-31
Abstract: PURPOSE:To prevent the destruction of storage data and to freely switch a signal by providing a circuit, which prohibits the output of a selective refresh signal to a memory circuit for a constant time, when a switching signal is switched. CONSTITUTION:When a refresh signal selecting circuit 24 is switched by a switching signal 22, the output of a selective refresh signal 27 sent from a refresh signal selecting circuit 24 is prohibited for a constant time by an output prohibiting circuit 25. In such a constitution, even if the selecting signal 27 is outputted immediately before the switching and the refresh signal 27 is outputted again from a switching destination device, since the output of the refresh signal 27 from the switching destination device is prohibited by an output prohibiting circuit 25, the output of the refresh signal 27 during a refresh busy time is eliminated, the stored data are not destroyed, and asynchronous refresh signals 20 and 21 can be freely switched.

Title: Traverse cam
Inventor: TERANISHI JUNICHI
IPC: B65H54/28
Filed: 1990-08-20
Abstract: PURPOSE:To heighten the winding density of a package and prevent the generation of irregular selvage by forming the cam groove of a traverse cam in such a way that an angle at its intermediate part is smaller than an angle at both end parts thereof. CONSTITUTION:A traverse cam 11 is provided with a cam groove 12 formed with a specified angle from the rotating direction A. This cam groove 12 is formed in such a way that an angle theta2 at its intermediate part is smaller than an angle theta1 at both end parts 13 thereof. The cam groove 12 is therefore formed into bent shape at boundaries between both end parts 13 and the intermediate part 14. In a take-up package 18 formed of such a cam 11, the tapered angle alpha2 of an intermediate part 20 becomes smaller than the angle alpha1 of both end parts 19. The package 18 therefore has the high winding density of a yarn layer in its intermediate part 20 so as to increase the whole winding weight. Since the winding density in both end parts 19 is relatively lowered, the generation of irregular selvage and the fall of an end face are prevented.

Title: Motor
Inventor: SEKINE SHOZO
IPC: F16C25/04
Filed: 1990-08-18
Abstract: PURPOSE:To prevent a noise from being made by collision of a rotor shaft and a pivot sheet when the frequency is cut off for making a low-noise motor system by bringing the shaft into constant contact with a pivot by the elasticity of a spring-shaped washer. CONSTITUTION:When the power source frequency to a stator core 9 in which an oil fan motor changes from powerful combustion to weak one is cut off, a torque of a blowing fan 2 disappears in a moment. Therefore, the blowing fan 2 tries to move to the opposite side of a fan guard 3, causing the end of a rotor shaft 6 to try go away from a pivot sheet 10. However, the elasticity of a wave washer 11 pushes the rotor shaft 6 back to keep the end of the rotor shaft 6 into constant contact with the pivot sheet 10. When the stator core 9 is allowed to conduct again, the blowing fan 2 rotates, moving to the side of the fan guard 3 again.

IPC: H03K19/003
Filed: 1990-08-17
Abstract: PURPOSE:To prevent a through-current from flowing to an output buffer by controlling the delivery of a voltage level to a transistor(TR) in the output buffer when the voltage level of an input voltage changes. CONSTITUTION:With an input signal IN at an H level, other input N2 of a NAND gate 6 and a NOR gate 7 goes to an H level, an output signal S1 of the NAND gate 6 and an output signal S2 of the NOR gate 7 go to an L level and an output signal OUT goes to an H level. When the input signal IN goes to an L level, the output signal S1 of the NAND gate 6 goes to an H level and a transistor(TR) 2 is turned off. Then the other input N2 goes to an L level with a prescribed time of delay from the input signal IN and the output signal S2 of the NOR gate 7 goes to an H level, a TR 3 is turned on thereby allowing the output signal OUT to go to an L level. Thus, the possibility of simultaneous turning-on of the TRs 2, 3 is zero and no through-current flows to the output buffer 1.

IPC: H01F5/00
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To detect a defect of a pipe-shaped object to be tested in a circumferential direction with high accuracy by a constitution wherein a coil formed in disk shape is disposed in an inner circumferential portion of the object to be tested such that a central face between both of edge faces includes a central axis of the object to be tested. SOLUTION: Eight pancake type coils 5 held by a cylindrical body 6 are disposed on two planes crossing perpendicularly by four pieces such that the centers of the coils are away from the central axis of the body 6 at the same distance. A central face between both of edge faces of each of the coils includes the central axis of the body 6. The coils 5 are connected from one in one plane to one in another plane to form two series circuits to be used as operation coils. When AC currents 3 are applied to the coils 5, eddy currents 3 which are parallel to the central axle of the body 6 are generated. The eddy currents 3 are varied by being affected by the defect 4 in the circumferential direction, thereby causing the variation of an impedance of the coil 5. As a result, it is possible to readily detect a defect in the circumferential direction with high accuracy.
