Title: Polyphase clock generating circuit
Inventor: OOTA HIROSHI
IPC: G11C19/00
Filed: 1984-05-28
Abstract: PURPOSE:To reduce the variance of clocks and the skew of the clocks having respective phases by forming a means for executing the previously determined logical operation of an output from a prescribed stage of the 1st shift register and an output from a prescribed stage of the 2nd shift register. CONSTITUTION:A signal outputted from a reference clock oscillating circuit 1 is multiplied by a multiplying circuit 2, which outputs the 1st and 2nd multiplied clocks which have previously fixed phase difference. The 1st and 2nd multiplied clocks are inputted respectively to the 1st and 2nd n-stage shift registers 4, 5 for executing shifting operation synchronously with the reference clock. The reference clock is applied to the register 4 and a previously determined reference clock outputted from a delay element 3 is applied to the register 5. The previously determined AND of output signals 11-1-11-4 and output signals 12-1-12-4 outputted from the 1st 4th stages of the registers 4, 5 are found out by AND gates 6-1-6-4. Consequently, the variance of respective clocks is reduced and the skew of respective clocks in respective phases is reduced.

Title: Condition branching circuit
Inventor: KOBAYASHI NOBORU
IPC: G06F9/32
Filed: 1983-06-17
Abstract: PURPOSE:To attain a quick processing after a condition branching instruction is generated, by obtaining the AND of plural order modes corresponding to appearing order detected results of plural external input flags and sequentially supplied plural condition setting signals. CONSTITUTION:An order detecting circuit 11 receives plural flags F0-Fn and detects that the received flags correspond to which one of previously fixed plural order modes, and then, sets the logic of one corresponding order mode output M1-Mk (k<n) to ''1''. The outputs M1-Mk, condition branching enable signal E, and condition setting signals C1-Ck which are successively generated after the signal E is generated, are inputted into AND gates G1-Gk. Since each of the signals C1-Ck appoints that which branching instruction is to be executed and the logic of the signal E becomes ''1'' only when a condition branching instruction is executed, the gates G1-Gk operate only when the condition branching instruction is executed and the outputs of the gates G1-Gk become address load signals A to a program counter through an OR gate G.

Title: Dc-to-dc converter
Inventor: SATO MORIO
IPC: H02M3/28
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To improve surge voltage and switching noise produced when a first switch element is turned off and allow the switch operation to be handled by software, by connecting a circuit for producing pulses with specified pulse width between the output terminal of an oscillation control circuit and the control electrode of a second switch element. SOLUTION: Exciting energy is accumulated in a second transformer 11 by current passed through the primary winding 11a of the second transformer 11 during the on-duration of a second switch element 12. When the second switch element 12 is turned off, the exciting energy flows the secondary winding 11b through a second diode 16 to a first capacitor 15 and is stored there. Since the on-duration of the second switching element 12 is set to a specified value, the stored voltage is in proportion to the voltage of a direct-current power supply 1. The number of turns of the tertiary winding 2c of a first transformer 2 is matched with that of the primary winding 2a and further the on-duration of the second switch element 12 is selected so that the charging voltage of the first capacitor 15 is twice the voltage of the direct-current power supply 1.

Abstract: PURPOSE:To effectively pump up sea water by simple composition by making constitution in which a wave receiving plate is oscillated by the pushing energy of waves, and a piston is reciprocatively moved in a cylinder to suck water to be sent. CONSTITUTION:A wave receiving plate 10 is installed in a water-intaking part, and is provided so as to be repeatedly oxcillated before and behind with its side surface being pushedly moved by waves.

The negative pressure in the right cylinder chamber of the piston 20 due to its rightward moving sucks water in the cylinder 26 from an intake 28 via an intaking duct 30a, and on the other hand, sends water housed in the left cylinder chamber upward via a delivery duct 34b. Next, the leftward moving of the piston 20 delivers water in the right cylinder chamber and also sucks water in the left cylinder chamber.
