Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To enhance the C/N ratio (carrier/noise ratio) of an output signal of a prescaler circuit. SOLUTION: An output and its inverted output from a 1/2 frequency divider consisting of a dynamic flip-flop 29 and inverters 9-11 are fed to a signal selection circuit 30, the selection state of the signal selection circuit 30 is inverted every time the level of an external control signal m changes and the output of the signal selection circuit 30 decides the timing when the signal selection circuit 30 receives a level change in the external control signal (m). Furthermore, a dynamic flip-flop 31 is used to synchronize the output of the signal selection circuit 30 with an input clock XIN and the output is used for a frequency division signal.  Thus, the signal selection circuit 30 continues 1/2 frequency division while the level of the external control signal (m) is constant and the signal selection circuit 30 conducts 1/3 frequency division only once just after the level of the external control signal (m) changes.

Title: Structure for sealing distribution plate
Inventor: KAMIYOSHI YUSUKE
IPC: B28B23/02
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To dispense with an annular concave groove by having a distribution plate including a shaft hole and a grout hole, and a sealing material which has elasticity, covers the peripheral portion of the distribution plate, and allows a portion thereof positioned on a pressure transmission surface of the distribution plate to function as a sealing portion. SOLUTION: A distribution plate includes a shaft hole 3 and a grout hole 4. A sealing material 2 has elasticity, and covers a peripheral portion 5 of the distribution plate. The sealing material 2 allows a portion thereof positioned on a pressure transmission surface 6 of the distribution plate to function as a sealing portion 7. The thickness of the sealing member 2 on the pressure transmission surface 6 is determined such that when a tensile force of a tension material T is released, the sealing material 2 is deformed between the distribution plate and a concrete product C to be in close contact with both of the same, to thereby prevent formation of a gap from which grout leaks.  Thus, only by bringing the pressure transmission surface 6 of the distribution plate into contact with the concrete product C to introduce a tensile force, the sealing portion 7 is deformed, whereby the gap between the pressure transmission surface 6 and the surface of the concrete product C is sealed. As a result, the grout material can be effectively prevented from leaking.
