Title: Running operation automatic change over device for moving body
Inventor: SHOJI MITSUAKI
IPC: E05C17/64
Filed: 1993-06-29
Abstract: PURPOSE:To temporarily halt the running of a heavy sliding door mounted to a hospital, an office, a library, a housing for the ages and a warehouse or the like, or a moving body such as a carrier, and prevent the movement of the moving body in the reverse direction within a specified torque and change over automatically operation control, say, opening and closing of the moving body in emergency, such as fire, thereby preventing the generation of a disaster. CONSTITUTION:A moving body is installed so that it may run along a running passage. A rack gear 4 is mounted between the moving body and the running passage on one hand while a pinion gear 9 is mounted on the other hand, thereby forming a control section by the engagement between both gears, and, what is more, a two-way engagement clutch mechanism 12 is incorporated in the pinion gear. It is so arranged that the moving body may be halted temporarily at an arbitrary position in the control section while the movement of the moving body in the reverse direction may be blocked within a specified torque. In addition, a change over mechanism, which releases the engagement with the rack gear with an electric signal, is installed to the pinion gear, thereby controlling the moving body so that it may be kept in a free state.

Title: Sliding contact material
Inventor: SAGAWA TAKAAKI
IPC: H01H1/025
Filed: 1981-12-25
Abstract: PURPOSE:To obtain a Ti-Cu type sliding contact material with low and stabilized contact resistance as well as enhanced wear resistance by adding a restricted amount of one or more among Nb, In, Ba and Cd to a Ti-Cu alloy having a specified composition. CONSTITUTION:A sliding contact material is obtd. by adding 0.5-10wt% in total of one or more among Nb, In, Ba and Cd to a Ti-Cu alloy consisting of 2.4- 3.4% Ti and the balance Cu without changing the compositional ratio. The reason that 0.5-10% in total of one or more among Nb, In, Ba and Cd is added to the Ti-Cu alloy is that the added element acts as a lubricant to enhance the wear resistance and lubricant powder produced by wear is soft and is easily removed by sliding action to keep the contact resistance low and stable. In case of <0.5% of the element, the effect is not shown, and >10% of the element increases the amount of formed oxide and makes the contact resistance high and unstable.

Filed: 1988-08-25
Abstract: PURPOSE:To easily decide whether a cuff and a pulse wave detecting means are abutted on appropriate positions on an artery or not by increasing cuff pressure up to reference pressure and increasing the cuff pressure until the extinction of the amplitude of a pulse wave is detected when the amplitude of the pulse wave is reference amplitude or above. CONSTITUTION:A cuff pressure control means 4 drive-controls a pump 3, when cuff pressure P by a cuff 1 reaches reference pressure P0, the increase of the cuff pressure P is temporarily stopped, amplitude V of the pulse wave is compared with reference amplitude V0, and when the amplitude V is lower than the reference amplitude V0, the cuff pressure control means 4 inversely drive-controls the pump 3 and pressure-reduces the cuff pressure P, and a person to be inspected arbitrarily dislocates the positions of the cuff 1 and a pulse wave detecting means 2 and restarts the inspection. When the cuff 1 and the pulse wave detecting means 2 are abutted on the appropriate positions by trial-and-error in this manner, the amplitude V of the pulse wave becomes the reference amplitude V0 or above. At that time, it is informed to the person to be inspected that the pulse wave can be properly detected. The cuff pressure control means 4 further increases the cuff pressure P and stops the increase of the cuff pressure P when the extinction of the amplitude V of the pulse wave is detected, and blood pressure is measured from cuff pressure Pcs from which the amplitude V of the pulse wave is extinct.

Filed: 1987-08-26
Abstract: PURPOSE:To quickly and surely extract an intruder with an easy processing even if which color a person intruding into a monitor area is dressed in or whatever intrudes into the monitor area, by dividing the background face of the monitor area into plural areas and patterning prescribed areas of these divided areas. CONSTITUTION:The background face of a monitor area 7 is divided into plural areas, and prescribed areas of these divided areas are patterned 9. When an arbitrary intruder intrudes into the monitor area 7, a relative color difference is generated between this intruder and a patterned area or an non-patterned area. That is, the difference threshold processing is effectively used because the background face of the monitor area is divided into plural areas and prescribed areas of these divided areas are patterned, and consequently, an inexpensive monitor device of high precision is obtained which quickly and surely extracts the intruder by the easy processing even if which color the person intruding into the monitor area is dressed in or whatever intrudes into the monitor area.
