Title: Expanding anchor
Inventor: PEETAA FUREERITSUHI
IPC: F16B13/06
Filed: 1988-06-08
Abstract: An expansion dowel assembly includes an expansion sleeve, an expanding member and a bolt for pulling the expanding member into the expansion sleeve. The expansion sleeve has a leading end and a trailing end with a bore extending between its two ends. At the leading end, the bore is conically shaped and converges toward the trailing end. From the trailing end of the conically shaped section, the bore is cylindrically shaped and extends toward the trailing end to another smaller diameter cylindrically shaped section of the bore. At the transition between the two cylindrically shaped sections there is a stop shoulder which limits the pulling-in action of the expanding member and the radial widening of the expansion sleeve.

Title: Paper sheet carrier
Inventor: ARASHIDA TOSHIO
IPC: G03G15/00
Filed: 1994-05-31
Abstract: PURPOSE:To reduce the carrying resistance of a paper sheet in a curved section and to obtain nipping pressure suited to the thickness of the paper sheet by providing a curved guide plate for forming the outer peripheral guide face of a curved carrier path so as to be oscillatable centering around a shaft near the head in a carrying direction, and energizing the curved plate toward an inner periphery. CONSTITUTION:In the case where a thin paper sheet 2 (shown by a dotted line) is in passing, force for energizing a curved guide plate 11 in a direction designated with the arrow A does not exist or is weak. Thus the curved guide plate 11 is energized in a direction designated with the arrow B by the tension of a tension coil spring 13 to form a curved carrier path having a large curvature. During the passing of a thick paper sheet 2 (shown by a solid line), the toughness or restoring force of the paper sheet 2 surpasses the force of the tension coil spring 13, and the curved guide plate 11 therefore rotates in a direction designated with the arrow A to reduce the curvature of the curved carrier path 10. Since the frictional resistance of the paper sheet 2 passing through the curved carrier path 10 is therefore reduced, even if nipping pressure between skew rolls 8b, 8c is small, the smooth carrying of the paper sheet can be carried out.

And if the magnetic particle having such a cover layer is applied to a resin bonded magnet, a bonded magnet materializes, in which the degree of freedom in shape is large and the magnetic property is high.

Title: Logical simulation method
Inventor: MIZUNO HIROSHI
IPC: G06F19/00
Filed: 1988-06-07
Abstract: PURPOSE:To perform the logical simulation at a high speed by processing the event to the same element in accordance with the probability where the states of plural input terminals of said element are changed in the same time point. CONSTITUTION:The definition of such an element that is evaluated after the update process of the state of an input terminal is carried out to each element in a circuit to be simulated in accordance with the probability where the states of plural input terminals of said element are changed in the same period of time. The element having the low probability for simultaneous change of the input terminals is defined as an element that is evaluated after the update process of the input terminal state. The simultaneous change of the input terminal states are not easily produced for those elements even though the evaluation of elements and the registration of new events are carried out when the state of the input element is updated. Thus the redundant processes like the re- evaluation of the same element, the cancel of events, etc., are not substantially produced. Thus it is possible to perform the high-speed logical simulation regardless of the probability where the states of plural input terminals are changed at the same time point of each element.

Filed: 1992-05-01
Abstract: PURPOSE:To enable stereophonic regeneration by an existent radio receiver by separating a received AM stereophonic broadcast signal into a sum signal and a difference signal by a matrix circuit, and converting them into FM stereophonic waves and sending them. CONSTITUTION:A broadcast wave inputted to an AM tuner 1 is sent to a demodulator 5 and one signal out-of-phase wave of the sum signal and difference signal of a left and a right channel is separated into a left and a right audio frequency. An FM stereophonic modulation part 6 imposes FM modulation on the separated signals, and the sum signal and difference signal are transmitted as one signal wave over the main channel and subordinate channel respectively. Then, the received AM stereophonic broadcast wave is modulated into an FM stereophonic broadcast wave, which is resent and regenerated by the existent FM receiver. Consequently, the stereophonic broadcast can be listened to at low cost without purchasing an expensive AM stereophonic receiver.
