Title: Pulse monitor
Inventor: JIKIBA YASUHIRO
IPC: A61B5/0245
Filed: 1987-07-10
Abstract: PURPOSE:To conserve power consumption by certainly cutting off the power supply of a pulse wave measuring part after the elapse of a predetermined time, by discriminating the difference between a pulse wave signal and noise other than a pulse wave and continuing the measurement of a time for automatic power-OFF for the input of noise. CONSTITUTION:The frequency corresponding to the min. pulse rate among the pulse rates measurable from a living body is set to f1 and the frequency corresponding to the max. pulse rate is set to f2 and only the signal present within a range from the lower limit frequency f1 to the upper limit frequency f2 in the detection output due to a pulse wave sensor 2 is regarded as pulse wave input to clear the count number of an automatic power-OFF counter 7. When a signal not present within said range, that is, a signal having an extremely short cycle or a signal having an extremely long cycle is inputted, said signal is judged as noise to continue the counting of the counter 7. Therefore, when pulse like noise low in repeating frequency or continuous noise high in repeating frequency enters accidentally, the power of a pulse wave forming circuit 3 is cut OFF after a predetermined time without clearing the counter 7.

Title: Method for driving ac-dc combined electric discharge display
Inventor: ASAI HIDEYUKI
IPC: G09G3/294
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a driving method for surely erasing wall charges in a non-display discharge space when an AC-DC combined discharge display is driven in the way to erase wall charges in a non-displaying discharge space after wall charges are accumulated in all the discharge space. SOLUTION: When an AC-DC combined PDP is driven in processes including a wall charge accumulating process from a time t1 to t2 , a wall charge erasing process from a time t3 to t4 , and a display discharging process from a time t5 to t6 , the wall charge erasing process is performed in a state that a potential difference is provided between electrodes by applying a negative voltage Vc =-30V to a second memory electrode according to the difference in electric characteristic between a first memory electrode (M1 ) and a second memory electrode (M2). Therefore, although the memory electrodes M1 , M2 have different electric characteristics from each other in the wall charge erasing process, their wall charges are accumulated with similar easiness. Thus, in the non- display cell, a similar well charge quantity is accumulated on the memory electrode in the wall charge erasing process.

Abstract: PURPOSE:To process a video information signal and left/right audio signals into digital signals by one system of A/D converter by providing an input changeover switch to apply A/D conversion to a video information signal during asynchronizing period and to apply A/D conversion to a left audio signal and a right audio signal and video information signal during the horizontal synchronizing period. CONSTITUTION:After a video signal input 7 is clamped by a video clamp circuit 1 and inputted to an input changeover circuit 2. The input changeover circuit 2 selects a video signal 8 while effective video information exists, a left audio signal 9 or a right audio signal 10 subject to band limit by low pass filters 18, 19 during the horizontal synchronization period respectively is selected and inputted to an analog video signal input terminal of the A/D converter 3. The video image data is transferred to a video data latch 4 and the left and right audio signals are transferred to the audio latches 5, 6 in the A/D converter 3. Thus, since one A/D converter converts not only the video signal but also the audio signal into a digital signal, the cost is considerably reduced in comparison with a conventional circuit.

Title: Treatment of sewage and waste water
Inventor: YAMASHITA TOSHIO
IPC: C02F1/24
Filed: 1982-10-02
Abstract: PURPOSE:To make systematic use of a titled method as a pretreatment for a secondary treatment, by producing foam by making use of the surface active materials in sewage, and treating separately the foam which floats while picking up suspended matter and the materials which partly flocculate, submerge into water and flow out. CONSTITUTION:A suitable amt. of air is continiously fed to the bottom side part of a foam sepn. tank and is diffused in the sewage to produce foam by making use of the surface active materials in the sewage. The foam which floats while picking up the suspended matter in the water is extruded into a defoaming tank, where the foam is liquefied by a defoaming liquid. On the other hand the liquid resulted from the flocculation of a part of the once separated foam and the submergence into the water is flowed out into an attached flotation tank where the flocculated materials are easily floated to form scum. The scrum is scrapped down into said defoaming tank and is treated together with a foam breaking liquid. The systematic use of the foam sepn. method as a pretreatment for a secondary treatment is thus made possible.

Abstract: PURPOSE:To provide an insect-repellent, dissipating the insect-repellent component slowly, and enabling the ready confirmation of the insect-repelling capability, by applying an oil-impermeable patterned layer to a surface of an oil-permeable sheet which turns transparent with oil, and impregnating the obtained substrate with a volatile oily insect-repellent which is liquid at normal temperature. CONSTITUTION:A patterned layer 3 having laminar linear patterns of e.g. a properly colored acrylic resin material is formed on the back surface of an oil- permeable sheet (e.g. paper, nonwoven fabric, etc.) which turns transparent with an oil. A covering material 4 is bonded to the sheet with an adhesive 5 in a manner to cover the surface of the patterned layer 3, and the sheet 2 is impregnated with an oily insect-repellent which is liquid at normal temperature and vaporizes slowly at normal temperature. The surface of the covering material 4 is coated properly with a layer of an adhesive or a pressure-sensitive adhesive 6. The patterned layer developed distinctly at the surface by the impregnation of the oil insert-repellent gradually loses its distinctness according to the dissipation of the agent, and then disappears partly. The insert-repelling capability of the material can be accurately displayed thereby.

Title: Method and apparatus for supplying granular powder
Inventor: NOMURA TOSHIYUKI
IPC: B65B1/16
Filed: 1982-10-01
Abstract: PURPOSE:To prevent blocking in case of sucking granular powder from a tank to the next process for air transport by letting granular powder flow into space behind a delivery port to such a degree that the space is not filled with the granular powder, and gradually decreasing pressure among particles of granular powder toward the delivery port. CONSTITUTION:A plate member 3 is projected above a delivery port 1 in a tank 0 to restrain settling of granular powder P, so that the granular powder P is forced to flow into space formed by the plate member 3, the base of the tank and the side walls of the tank and form a specific rest angle to be static. Accordingly, space 11 where there is no granular powder P is formed in the upper portion of the granular powder. This results in gradually decreasing pressure among particles of the granular powder P toward the delivery port to enhance fluidity of granular powder. In this arrangement, blocking is prevented to smoothly supply granular powder.
