Patent JP-S61170128-A (JP)
Title: Input buffer circuit
Inventor: UEMATSU AKIRA
IPC: G11C11/409
Filed: 1985-01-23
Abstract: PURPOSE:To decrease current consumption by providing a control circuit having a function controlling a current level of a constant current circuit making a constant current flow to a detection circuit detecting an input level signal to an input buffer circuit used for a semiconductor device such as a semiconductor memory. CONSTITUTION:When a setting potential Vs fluctuated with a change in a TTL signal VIN reaches a predetermined value, P-channel MOS transistor (P)10 and an N-channel MOS transistor (N)10 are saturated, an output signal Vout starts changing rapidly, the N12 detects the Vs to flow a current in response to the level to a circuit system comprising a P13 and the N12. Then the P13 reaches a gate-source potential in response to the current level. Since the gates and sources of the P12 and P13 are used in common, the gate-source voltage of the P12 is obtained finally in response to the setting potential Vs. On the other hand, the drain-source potential of the P12 is set so that the P12 is saturated. While the P10 and the N10 are in the saturated region, a constant current flows depending not on the power supply voltage VDD but on the P12 and a logic level independently of the voltage VDD is obtained.

Abstract: PURPOSE:To obtain a photoelectric smoke sensor which is influenced by completely none of light source variation, window fouling of a light source and photodetecting elements, sensitivity variation of the photodetecting elements, etc. CONSTITUTION:A short-pulse which is generated by a one-shot pulse circuit 5 at every 1-5sec drives a light source driving circuit 7 to turn on the light source 4 for sensitivity compensation and also starts a timer circuit 6. Light from the light source 4 is photodetected directly by a photodetecting element 2 and photodetecting element 3 for sensitivity compensation and amplified by amplifiers 9 and 10, then a dividing circuit 11 calculates and stores the ratio in memory 12. The light source driving circuit 8 is driven after a fixed time counted by the timer circuit 6 to allow a light source 1 for smoke sensing to emit light. The light from the light source 1 is photodetected directly by the photodetecting element 3 for sensitivity compensation and if there is smoke at a smoke sensing part E (hatched in figure), scattered light from it is photodetected by a photodetecting element 2 for smoke detection. In this case, two photodetecting element signals are amplified and the dividing circuit 11 calculates their ratio as well. This ratio is sent to a dividing circuit 14 together with the former ratio stored in the memory 12.

Abstract: PROBLEM TO BE SOLVED: To conduct easy attachment of a seal member. SOLUTION: A holding member 30 is provided which is a part separated from a female connector housing 10 and is enabled to be mounted on this female connector housing 10. Attachment of a seal member 20 to the female connector housing 10 is conducted before the holding member 30 is mounted thereon. In this event, both an extention part 22 and a held part 23 are housed in an introduction part 13 without being bent. Thereafter, when the holding member 30 is mounted on the female connector housing 10, two engagement parts 32 engage with the held part 23 so as to sandwich it from both sides and the seal member 20 is thereby held in an off-regulation state. In the event that the seal member 20 is put to attachment, neither the extention part 22 nor the held part 23 are bent elastically and resistance against attachment is accordingly reduced, and therefore attachment can be conducted easily.
