Title: Optical logical circuit
Inventor: INOUE NAOHISA
IPC: G02F3/00
Filed: 1984-06-07
Abstract: PURPOSE:To obtain an optical logical circuit containing an optical AND circuit, by switching the propagation of light in accordance with existence/nonexistence of an impressed voltage to two switching section electrodes installed on a light guide. CONSTITUTION:When both input optical signals IinA and IinB are ''0'' in logical value, the output signal Iout is ''0'', since optical electromotive force elements 21 and 22 generate no electromotive force. Moreover, when the logical values of the signals IinA and IinB are respectively ''1'' and ''0'' or ''0'' and ''1'', the signal Iout is ''0'', since only either one of the elements 21 and 22 generates electromotive force. When both the signals IinA and IinB are ''1'' in logical value, voltages are produced in the elements 21 and 22 by the light propagated through light guides 11 and 12 and respectively applied to electrodes 24 and 23. Therefore, the light of the light input section 13a of a light guide 13 is propagated to a light output section 13b through narrowed sections 14 and 15 and intermediate section 13c, and the signal Iout becomes ''1''.

Abstract: PURPOSE:To obtain a large storage capacitance without widening the occupational area on a chip, by utilizing a portion of the bottom face of a trench in the surface of the substrate in which a transfer transistor for a memory cell is being formed. CONSTITUTION:The trenches 23 reaching the substrate 21 are formed through the N epitaxial layer 22 lying on the P-type Si substrate 21 by RIE. At the bottom of each trench 23, the P layers 24 are formed. After the thermal oxide thin films 25 are formed, poly-Si 26 is embedded in the trench 23. RIE forms again the trenches 23' which are formed a little more deeply than the trenches 23 and in perpendicular to them. After the gate films 27 for transfer transistors are formed, ion-implanted and regulated inn the threshold value, poly-Si 28 is embedded into the trenches 23'. On islands surrounded by the trenches 23, 23', the capacitor gate films 30 are formed. Next, outside of the connecting sections 33 of the bit wire 32, the capacitor electrodes 31 are selectively formed, and then the inter-layer insulating films 34 and the bit wire 32 are formed. Since the N layers 22 under the connecting sections 33 and capacitor electrodes 31 serve as drains and sources, specific forming is not required. Moreover, if the poly-Si sections 26, 28 outside of the gate electrodes of the transfer transistors are connected to the capacitor electrodes 31, the sides of the islands can be utilized and a large capacitance memory device having a high density can be provided.

Title: Blood pressure monitoring device
Inventor: NAKAGAWA TSUNEO
IPC: A61B5/022
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a blood pressure monitoring device easily mountable on a living body without afflicting the living body with much burden, and capable of accurate blood pressure monitoring. SOLUTION: The amplitude of a photoelectric pulse wave detected from a photoelectric pulse wave sensor easily mountable on the epidermis of a living body is normalized and the rising angle α of the photoelectric pulse wave whose amplitude has been normalized is calculated. A blood measurement startup means 72 starts sphygmomanometry using a sphygmomanometry means 60 when a variation Δα in the rising angle α calculated by a rising angle variation calculation means 68 has exceeded a preset criterial range (-β to +β).  Therefore, the amplitude of the photoelectric pulse wave is normalized and kept from being affected by changes in the mounted condition of the photoelectric pulse wave sensor 40, and sphygmomanometry is executed by the sphygmomanometry means 60 when blood pressure abnormality is detected from the variation Δα in the rising angle of the photoelectric pulse wave C1 . Thus, in order to reduce the delay of blood pressure monitoring, blood pressure measurements are prevented from being unnecessarily made in short cycles, and therefore the frequency of blood pressure value measurements using a cuff 10 is reduced to reduce the burden of the living body and to enable accurate blood pressure monitoring.
