Title: Designation method of defective minor loop of magnetic bubble memory
Inventor: ANDOU TETSUYA
IPC: G11C11/14
Filed: 1983-03-16
Abstract: PURPOSE:To obtain a magnetic bubble memory device low in error rate and high in reliability by designating a minor loop as a defective minor loop when two adjacent minor loops are defective minor loops. CONSTITUTION:For minor loops 1-(n-1), n, (n+1)-m, those marked O are designated as normal minor loops, and those marked X are designated as defective minor loops. In this way of designating defective minor loops, besides minor loops (n-1) and (n+1), checked out by examination, a minor loop n between them is also designated as a defective minor loop. By such a way of designating minor loops, minor loops having the possibility of becoming high in error rate are skipped as defective minor loops and not used. Thus, error rate of the device beocomes low and reliability becomes high.

Title: Optical setting and resetting flip-flop circuit
Inventor: NAGASHIMA KUNIO
IPC: G02F3/00
Filed: 1983-03-15
Abstract: PURPOSE:To obtain an optical setting and resetting FF circuit which sets and resets the quantity of projection light between two values by a light signal by using an optical bistable element and an optical inverter. CONSTITUTION:The projection light 203 of the optical bistable element 102 holds to the quantity P0 or P1 of light. When a set light signal 200 which has the predetermined quantity Ph of light is applied to an end surface 100 while the projection light 203 of the element 102 has the quantity P0 of light, the projection light 203 of the element 102 has the quantity P1 of light and holds it thereafter as long as bias light Pb is applied to an incidence terminal. The optical inverter 105 when applied with a light signal with the prescribed quantity Pb of light at its incidence terminal generates no projection light. Consequently, the projection light 203 of the element 102 returns to the quantity P0 of light and holds it thereafter as long as the bias light Pb is applied to the incidence terminal. Namely, the optical bistable element 102 has bistable characteristics as characteristics of the quantity of projection light to the quantity of incident light.

Filed: 1982-03-18
Abstract: PURPOSE:To prevent a violent change in torque owing to changing-over of the air-fuel ratio, in an air-fuel ratio change-over method for an internal-combustion engine with which the ratio is changed over in accordance with the load to engine, by delaying the ignition timing so as to be later than the required ignition timing in the engine load range near the point of changing over and or the rich side of air-fuel ratio, when the ratio is to be changed over. CONSTITUTION:If the ignition timing is delayed from a required ignition timing by an MBT etc. in the engine load range near the point of changing over and on the rich side of air-fuel ratio, when the ratio is to be changed over to the lean or rich side on the change-over point of air-fuel ratio in accordance with the specified load to engine, a violent change of torque owing to changing-over of the ratio can be prevented. The amount of delay angle G for the ignition timing can be so arranged to have its maximum at the very point a of the change-over of air-fuel ratio, approaching gradually the required ignition timing E with increasing engine load. Thus a violent change of torque owing to change-over of the air-fuel ratio can be prevented.
