IPC: H04N5/335
Filed: 1985-05-25
Abstract: PURPOSE:To obtain a reading sensor simply in circuit construction and large in S/N by providing plural photodetecting elements to which a bias voltage is applied. CONSTITUTION:The cathode side of a photodetecting element 4 is respectively commonly connected to a bias common line 45. By the driving of a present signal switch 42, the light signal of the size corresponding to the photodetecting quantity from the photodetecting element 41 and the photodetecting pulse composed of the noise signal of the switch are obtained, and by the driving of a dummy switch 43, the dummy pulse of the noise only of the switch is obtained by a dummy common line 48. Consequently, the differential output of the photodetecting pulses and the dummy pulse is outputted from a differential amplifier 50, and then, for the output, the reading signal equivalent to the light signal photodetected truly by the photodetecting element 41, for which the noise is cancelled, is obtained. Because of the above-mentioned constitution, the IC formation of the circuit is easy, the switch noise can be decreased or removed and a large S/N can be obtained by a simple amplifying circuit.

IPC: A61P9/12
Filed: 1992-04-06
Abstract: PURPOSE:To obtain a hypotensive retaining agent, comprising diadenosine 5',5'''- p<1>,p<4>-tetraphosphate (Ap4A) as an active ingredient, excellent in regulating properties for blood pressure and having high safety. CONSTITUTION:The objective hypotensive retaining agent comprises an effective amount of Ap4A, having vasodilator action and expressed by the formula or its pharmaceutically permissible salt as an active ingredient. The effective amount is usually an amount enabling the induction of the hypotensive retaining action in hypotensive anesthesia in a human or other mammals so as to reduce the average arterial pressure to usually <50%, preferably <=40% before administering the medicine. This compound is capable of rapidly reducing the blood pressure from the start of the administration, retaining the objective blood pressure and quickly recovering the blood pressure by discontinuing the administration. The hypotensive retaining action in the anesthesia is not affected by a difference in an anesthetic agent. Furthermore, the bloodstream in the heart and brain is increased by this agent in a hypotensive amount with no undesired influence on the heart (reduction and change in heart rate) and causing acidosis or reduction in gas partial pressure in the blood.
