Title: Magnetic bubble device
Inventor: NOGAI KENGO
IPC: G11C11/14
Filed: 1984-11-28
Abstract: PURPOSE:To prevent a destruction of the data stored in a magnetic bubble device by laying a diode between plural gate circuits to be formed on a magnetic bubble chip and transfer a magnetic bubble and a lead terminal installed at a package to connect the gate circuit to an external circuit. CONSTITUTION:A diode Di is laid between an electric conductor pattern 6' and a lead terminal 6, and an electric conductor pattern 18' and a lead terminal 18.

Title: Pallet conveyor
Inventor: KISHI HIDEKAZU
IPC: B65G17/24
Filed: 1990-09-19
Abstract: PURPOSE:To improve production efficiency by arranging a track member capable of engaging with and disengaging from the lower surface of rollers below the rollers thereby reducing the pallet conveying time. CONSTITUTION:A pallet 4 placed on rollers 3 is conveyed at a relatively slow speed of chain rollers 17. The pallet 4 only is stopped by a stopper for instance at a specified position within the current work zone, and components C for assembly on the pallet 4 are supplied to the assembly work or the like. Then when the rollers 3 pass through a conveying zone from one work zone to the next, the lower surfaces of the rollers 3 come in contact with the top surface of a movable plate 5. This makes the rollers 3 rotate which in turn convey the pallet 4 at a speed relative to the movable plate 5 in the chain running direction. The pallet 4 is therefore conveyed over the conveying zone at a speed approximately twice the speed over the work zone.

Title: Protective circuit employing ptc element and protective element therefor
Inventor: TOSAKA HISANAO
IPC: H01C7/02
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To realize a safety protective operation for overvoltage, overcurrent and reverse current by thermally bonding two sheets of PTC element tightly to constitute a protective element thereby bringing the PTC element into a high resistance state in a short time upon occurrence of an abnormality. SOLUTION: When the output from a charger C is lower than 5V, a transistor Tr is turned off and only a PTC(positive temperature coefficient) element P1 is conducted to charge a secondary battery B. When a voltage of 5V or above is applied between terminals (a), (b), the transistor Tr is turned on and a PTC element P2 is conducted to generate heat instantaneously. Consequently, the resistance of the PTC element P1 is increased abruptly and output current from the charger C is interrupted. Since the PTC element P2 is also under high resistance state, discharge current from a secondary batter B is suppressed to a micro level even if the transistor Tr is turned on. Consequently, output current from the charger C and the secondary batter B is suppressed instantaneously even upon occurrence of an abnormal state where a Zener diode Z is conducted.

Abstract: PURPOSE:To accelerate a device access processing by omitting a first state for preparing device access following to a second bus cycle in the continuous bus cycles at continuous addresses. CONSTITUTION:An instruction decode execution part 2 detects instructions with the continuous bus cycles at the continuous addresses. At such a time, when there are three bus cycles, the execution part 2 makes a BS<1>T3 signal 9 active H and when there are two bus cycles, a BS<1>T2 signal 10 is made active H.
