Title: Counter circuit
Inventor: YAMAMOTO SEIJI
IPC: H03K23/66
Filed: 1990-09-06
Abstract: PURPOSE:To prevent the malfunction of this counter circuit by providing 2-stages of delay flip-flops generating a pulse to load an n-bit counter to the counter circuit so as to make the holding time of the counter sufficient. CONSTITUTION:When a clock signal 4 is inputted to a control 1 and the counted value reaches all '1', a carry-out 5 goes to '1' as an output. Then the output pulse of the carry-out 5 is given to a flip-flop 2, the input is delayed at a leading edge of the clock signal 4 and a QC output 6 is outputted. Then the outputted QC output 6 is given to a 2nd delay flip-flop 3 and the QC output 6 is delayed by the leading edge of the clock signal 4. The flip-flop 3 outputs a QC output 7 rising with a delay of a half period of the clock signal 4 from the leading edge of the clock signal 4 and the QC output 7 is inputted to a LOAD terminal of the counter 1. Thus, the hold time of the counter is sufficiently taken, thereby preventing the malfunction.

Title: Liquid resin mold
Inventor: KIKUCHI KEI
IPC: B29C39/02
Filed: 1984-11-14
Abstract: PURPOSE:To prevent a glass template from breaking and to offer a platelike molded article whose thickness accuracy is high, by a method wherein the titled mold is so constituted that a rigid spacer made of a synthetic resin-laminated material having a constant thickness is used and sealing properties are obtained by an elastic spacer made of silicon rubber adjoining to the rigid spacer. CONSTITUTION:Silicon rubber spacer 3 is arranged within a spacer 2 made of a synthetic resin-laminated material with which a base material is mixed in a state touching internally to the spacer 2. Bonding between resin through which cast molding is performed and the spacer 2 is prevented by inscribing the silicon rubber spacer 3 to the spacer 2 made of the synthetic resin-laminated material with which the base material is mixed. As the spacer 2 is made of the synthetic resin-laminated material with which the base material is mixed, there is no fear of breaking a glass template at all through difference of expansion, contraction and heat capacity as compared with a spacer made of metal, moreover, the spacer 2 is easy to process and dimensional accuracy is quite easily obtainable. In addition to the above, as the silicon rubber spacer 3 is very little thicker than the spacer 2, the spacer 3 is smashed up to the thickness of the spacer 2 when the spacer 3 is clamped, and air tightness is kept on by adhering closely a top force 1 and bottom force 1' to each other.

IPC: G06F3/06
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To quickly search a medium defect list at the time of converting a logical address into a physical address. SOLUTION: A medium defect list conversion part 22 subtracts an offset value from a physical address specified by an offset value on a medium defect list and transfers the subtracted value to a retrieval part 21. The retrieval part 21 specifies the offset value to the conversion part 22, so that the conversion part 22 converts the physical address indicated by the offset value on the list into a virtual logical address. The retrieval part 21 executes search based on the specified logical address and the virtual logical address obtained by the conversion part 22. The search is ended when a virtual logical address larger than the logical address appears in the medium defect list. The physical address is found out by adding the offset value obtained as a result of search to the logical address.

Title: Synchronizing signal separator
Inventor: KARIYA TETSUO
IPC: H04N5/08
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To extract a normal synchronizing signal quickly at All times from composite synchronizing signals with different periods and pulse widths. SOLUTION: A clamp circuit 12 clamps a composite synchronizing signal to make a SYNC tip level of the composite synchronizing signal match a 1st reference voltage Vref1. A comparator 13 compares the clamped composite synchronizing signal with a 2nd reference voltage Vref2 whose DC level is higher than that of the 1st reference voltage to separate the synchronizing signal. The clamped composite synchronizing signal is generated by charting/ discharging of a coupling capacitor 11. In this case, it is avoided that the level of the clamped composite synchronizing signal is lower than the 2nd reference voltage Vref2 when the period of the composite synchronizing signal is long by activating a switching element 20 to limit the discharge period.
