IPC: B21D1/05
Filed: 1979-01-23
Abstract: PURPOSE: To make possible the all hand work to be unnecessary at adjusting the correction work for the curling of the hoop, by detecting the size of curling of the hoop before it is introduced into the working roller, and by controlling the wheel base of upper and lower working rollers.  
     CONSTITUTION: The hoop (metallic thin sheet stored at the coiled state) 1 is pulled out into the direction D, and is passed under the detecting roller 12a between the guide rollers 11aW11d. The roller 12a is contacted with the hoop 1 by a light thrust force, and is lifted up correspondingly to the size of curling; the traveling distance (d) of the hoop 1, starting from a zero point where the curling is zero, increases with advance of uncoiling of the hoop 1. This traveling distance (d) is detected by the differential transformer 14, and the pulse motor 9 turns the control shaft 7 by the necessary angle into the necessary direction. Hereby, the worm wheel 6 is turned through the worm 7c, and vertically moves to the column 3a engaged with the worm wheel 6. With the increase of above traveling distance (d), the wheel 6 goes down, which makes the upper working roller to go down through the roller frame 4, and the wheelbase of working rollers is reduced.

Title: Clock signal driver circuit
Inventor: SUKOTSUTO EICHI AARU MATSUKUMA
IPC: H03K19/0175
Filed: 1994-01-26
Abstract: PURPOSE: To improve the flexibility on production and to reduce the cost by obtaining a version of a driving force which is different dependently upon whether a bonding wire is connected to an integrated circuit package or not. CONSTITUTION: When a variable clock signal driver 10 is used in environments of a high performance and a relatively high frequency, a low driver logic unit 12 and a high driver logic unit 14 are enabled to drive transistor TR output stages 26 and 28. This is achieved by connecting an optional bonding wire 31 between a bonding pad 30 and a ground pin 51A of a package 50. When the driver 10 is used in environments of a lower frequency, the bonding pad 30 is in the floating state. A package grounding sense circuit 20 disables the unit 14 in response to it. Consequently, the output stage 28 reduces a maximum operation frequency. Thus, an inexpensive packaging technique can be used.

Title: Game ball shooting apparatus
Inventor: FUKUSHIMA SHOGO
IPC: A63F7/02
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent a vibration noise by linking a base plate to a motor using a buffer link member having a rubber buffer and a pair of bolts fastened at both ends of a buffer shaft. SOLUTION: An arm roller 34 comprises a roller body 34a made of a sintered metal and a surface layer rubber 34b made of a urethane rubber fitted onto the external surface thereof. The body 34a of the roller is provided with a groove 34c with which 34 is engaged a ridge 34d of the surface layer rubber 34b to prevent the slipping of the surface layer rubber 34b. Even when the vibration of a stepping motor reaches a drive cam, the vibration is damped by the surface layer rubber 34b of the arm roller 34 so that the vibration will not be transmitted to the side of the arm roller 34, namely, a base plate or the like and hence, there is no noise as caused by resonance with the vibration of the stepping motor.  Thus, even in a motor so arranged to rotate with the accumulation of each very small quantity of displacement (step) like the stepping motor, no vibration is transmitted to the base plate thereby eliminating noise otherwise caused by resonance.
