Title: Clock extract method and circuit therefor
Inventor: NISHIWAKI KAZUYUKI
IPC: H04L7/027
Filed: 1993-06-23
Abstract: PURPOSE:To improve the convergence accuracy of a clock extract optimum point by not applying a minimum position to a post-stage averaging circuit with respect to the state that a minimum position of a carrier amplitude is considered to be faulty. CONSTITUTION:Position information representing a position in a symbol of a minimum value generated by a minimum position detection circuit 14 is fed to a number detection section 21a and a gate control section 21b of a condition discrimination circuit 21. The detection section 21a of the circuit 21 detects it when the position information from the circuit 14 is at least either of both end positions in the symbol and gives a detection signal to the control section 21b. The control section 21b interrupts the application of the position information from the circuit 14 to an averaging circuit 15 through gate control corresponding to the detection signal from the detection section 21a. Thus, since it is avoided that the erroneous position information fed to the circuit 15 is avoided, the circuit 15 averages only the minimum position with high reliability.

Title: Artificial joint
Inventor: OSAWA TAKAAKI
IPC: A61F2/36
Filed: 1993-06-23
Abstract: PURPOSE:To keep the fixation of an artificial joint and a bone from being lost with the lapse of time by forming a covering adhesive part for covering a gap between an artificial joint part and a living body bone. CONSTITUTION:An artificial joint (shelf) 11 comprises a fixing part 12, a sliding part 13 and a covering adhesive part 14. The shelf fixing part 12 is formed by Ti, Ti alloy, SUS 316, Co-Cr alloy, or the like and can be fixed to the shelf bone or bone cement. The sliding part 13 is formed from an ultra-high-molecular weight polyethylene and made closely adhere to the shelf fixing part 12. The covering adhesive part 14 is joined to the edge of the shelf fixing part 12 or the edge of the sliding part 13 to be connected to the periphery of the edge. The covering adhesive part is, preferably formed from a soft material because it is easily made closely adhere to the living body bone, but a hard material can be also used if it is previously formed in such a manner as to be matched with the form of the living body bone. Thus, abrasion powder such as polyethylene or the like can be kept from entering between the bone and the artificial joint or between the bone and cement so as to prevent loosening.

Title: Controlling method of inverter
Inventor: TAKAKADO YUUZOU
IPC: H02M7/515
Filed: 1978-12-08
Abstract: PURPOSE: To surely commutate the silicon controlled rectifiers of an inverter despite any change in a load, by automatically controlling a frequency and stopping the rise in the impedance of the load only when the commutation enabling conditions on the silicon controlled rectifiers are not satisfied.  
     CONSTITUTION: When a formula I is satisfied by adjusting multiplication regulators 1∼3, the output α5 of an additive proportional integration circuit 4 shows positive polarity and such setting is effected by a diode 6 that no instruction is applied to an adder-subtractor 5. As a result, an inverter is driven while it is controlled by only an inverter operation frequency setting signal α4. When the formula I becomes unsatisfied, the polarity of the output α5 of the integration circuit 4 is inverted to negative. At that time, the addersubtractor 5 undergoes subtraction control, reduces the frequency of the inverter and is automatically controlled to substantially reduce the impedance of a load. This results in surely commutating the load carrying silicon controlled rectifiers of the inverter despite any change in the load.
