Title: Locking structure of screw
Inventor: FUJITA SHIGERU
IPC: F16B39/04
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a screw locking structure the manufacturing of which is facilitated by a method wherein an elastic member having an elastic force in the penetrating direction is mounted in a mounting hole, pierced with a screw shaft, in such a state that the end part thereof is protruded from a hole port. SOLUTION: A mounting hole 21 is formed in a screw shaft 2 such that it extends therethrough and an elastic member 3 is arranged therein. The elastic member 3 is a compression spring made of a metal, the central part of a coil has a large diameter (b), and two end parts have a small diameter (c). The outside diameter of the large part 31 has size enough to allow close fitting of it in a mounting hole 21 and an overall length during non-compression is slightly longer than the hole length of the mounting hole 21. When the elastic member 3 is pressed in the mounting hole 21 and fixed through close fitting-in of large part 31, a small part 32 is slightly protruded from a hole part.  When a bolt is joined in a screwed-in state with a female screw part, the tip part of the elastic member 3 is pressed in the mounting hole 21 and through the repulsion force thereof, frictional resistance between the tip part and a female screw surface is increased and forms locking protection of the shaft part 2.

Title: Magnetic tape device
Inventor: ISHII TOSHIO
IPC: G11B15/43
Filed: 1987-05-15
Abstract: PURPOSE:To enable a rapid start for a tape travel by annunciating abnormality in response to an excessive tension signal, and preventing a tension from lowering based on a tape travel starting instruction signal and the excessive tension signal. CONSTITUTION:When a play switch 30 is manipulated, a tape travel starting instruction 38 is outputted from a microcomputer 34. At that time, when an excessive tension is detected by tension sensors 9a and 10a, outputs of comparators 40 and 41 are reversed to be H and switches 46 and 47 are turned on to light LEDs 44 and 45 so that the abnormality is annunciated. At the same time, the outputs of the comparators 40 and 41 trigger a monostable multi vibrator 52 via an OR-gate 49 and an AND-gate 51 so that the instruction 38 is cut off for a given period of time via an inverter 53 by an AND-gate 54. By this method, a capstan motor 11 will never be driven by a driver circuit 59 so that a tape tension will be prevented from lowering, while the LEDs 44 and 45 will never be put out of lights unless a tension arm position is manually adjusted. The tape travel can be commenced quickly and this is the same as in the case of fast forwarding and rewinding as well.

Title: Sheet packing with blank cap and production thereof
Inventor: TSUKADA ISAMU
IPC: B65D53/02
Filed: 1993-04-21
Abstract: PURPOSE:To prevent a blank cap from spring out of a cap to the outside when the cap is being put on a container body after it has been filled with contents by an automatic filling machine, etc., by forming the blank cap integrally with the inner part enclosed by sheet packing. CONSTITUTION:A sheet packing 3 has a peripheral wall 13 around its periphery and the upper face of the peripheral wall 13 in the vertical direction K is flat. A blank cap separating part 14 is formed around the inner periphery of the sheet packing 3 in the direction toward the center. A blank cap separating bank 15 is further formed around the inner periphery of the blank cap separating part 14. The blank cap separating part 14 has the same membrane thickness as that of the burr occurring when a sheet packing with a blank cap is produced and the sheet packing 3 and the blank cap 4 are separated along the blank cap separating part 14. Therefore, the sheet packing 3 and the blank cap 4 can be formed in a cap by a single process. Since the blank cap 4 is fixed in the cap together with the sheet packing 3, when the cap is put on a container body, the blank cap 4 will not spring out of the cap to the ouside.

Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality judging method of a machining device and a device thereof which discovers an abnormality of a transmission system of the machining device. SOLUTION: Control command data is sent from a CPU 110 to an output process circuit 104 to separate a grindstone 12 from a workpiece and rotate it at a predetermined number of revolution and then change over a motor 10 into a play rotation or braking condition. Moreover, a number-of-revolution sensor 20 is started to operate, and an internal timer 116 is started. Furthermore, when the time whose counting is started by the internal timer 116 reaches inspection timing, number of revolution data of a wheel spindle 14 sent from the sensor 20 is obtained by an input process circuit 106. Whether a machining device is normal or abnormal is judged depending on whether a change pattern of the number of revolutions which is obtained is within allowance width or not.  Consequently, it is possible to discover an abnormality of a transmission system due to slide and mechanical friction and prevent a failure of the transmission system without fail.

Filed: 1986-05-26
Abstract: PURPOSE:To attain miniaturization and light weight of the titled unit by providing a boosting means comprising plural stages of switching means switching a DC power voltage so as to eliminate the need for a boosting transformer. CONSTITUTION:Since transistors (TRs) 1, 2 control respective power supplies E1, E2 synchronizingly, both collector potentials go to zero with both the TRs 1, 2 turned on. Conversely, with the TRs 1, 2 turned off, the collector potential of both the TRs l, 2 goes respectively to E1, E2. Since the common line at the TR 2 is connected to the output of the TR l, a total output at a terminal 22 is a high voltage AC having the amplitude range of 0-+(El+E2)V. Since no boosting transformer is required, the miniaturization and light weight of the unit are attained.
