PURPOSE:To form an electrolyteless lead-acid battery having good low-humidity performance, long life, and good maintenability by pouring a mixed solution of dilute sulfuric acid and sodium hydroxide solution prepared by dissolving lapilli containing silicon dioxide in a lead-acid battery and charging it and removing the electrolyte and charging the battery again. CONSTITUTION:Sulfuric acid having ...

A surgical knife includes a handle supporting a diamond blade. An Nd/YAG laser is optically coupled by a bundle of optical fibres to the blade. The arrangement enables the blade to cauterize tissue being incised by the knife. The selection of the material of the blade and the laser provides a laser knife of extended useful life. The heating of the diamond blade by the laser provides the blade with...

Furthermore there is provided a starting preliminary circuit which operates by detecting external contact resistance, a proximity detecting circuit which operates by detecting changes in capacity between electrodes for detecting proximity and a moto...

PURPOSE:To facilitate the operation, heighten the durability and reduce the size, by making it possible to eliminate the unlocked state even if the seat is set in a walk-in state and by simplifying the structure. CONSTITUTION:The seat adjuster causes an upper rail 2 integrated with the seat to slide on a lower rail 1 fixed on the floor. When the back of the seat is turned down forth to set the sea...

PURPOSE:To have the seat designs unlimited to a specific design by dispensing with the need of installing the side support part as a separate body. CONSTITUTION:One pair of wings 2, 3 to the right and left are installed on the inner sides on the right and left both sides of a seat back frame 1, the side support parts on the right and left sides of the back pad to cover the wings 2, 3 are displaced...

PURPOSE:To facilitate free designs without need of installing a side support part in the constitution that one pair of wings to the right and left are installed on the seat back frame, and the side parts of a person on the seat are held from transverse directions by displacing them in multiple stages. CONSTITUTION:When a dial 15 is turned, a multiple-stage cam 13 is turned, wings 2, 3 are turned i...

PURPOSE:To facilitate an easy change of the check contents and an easy programming operation for a command checking system, by separating the check contents from a part where the check contents are decided and executed and handling the check contents in terms of data. CONSTITUTION:The command check contents are handled in terms of data and stored in an external memory 3. While the check contents a...

PURPOSE:To switch screens at a high speed by loading an external memory serving as a screen memory to a work station controller set at a remote place. CONSTITUTION:A specific key on the keyboard of a work station device 2 is operated, and this input of the key is transmitted to a central processing unit 3 via a work station controller 1, a communication circuit 5 and a communication controller 4. ...

PURPOSE:To measure easily the floating vibration characteristics of a magnetic head on the surface of a revolving magnetic disk and to improve the productivity, by irradiating laser beams in division to the back side of the magnetic head as well as to an interference reference reflector and making the reflected light of those beams incident to a photodetector. CONSTITUTION:The laser beam radiated ...

PURPOSE:To always ensure the stable tracking control regardless of the variance of light quantity by setting the same ratio of level change among the 1st, 2nd and 3rd signals due to the fluctuation of the reflection factor, etc. of an optical recording medium and fixing the zero-cross point of a tracking error signal. CONSTITUTION:The reflected beams (b) and (c) divided by a half mirror 18 are dec...

PURPOSE:To prepare a laminated sheet free from curling and good in stability by a method wherein an ultra-high molecular polyethylene (UHPE) sheet is arranged to both surfaces of a thermoplastic sheet and those sheets are processed under a specific condition. CONSTITUTION:A UHPE sheet is stacked to both surfaces of a sheet made of a theroplastic (e.g.; high density polyethylene) and the stacked sh...

PURPOSE:To improve the resistance to internal and external pressure, and to prevent the contents for a long period from deteriorating, by fitting a head body of molded thermoplastic into a trunk, and heating the truncated outer circumferential section and the annular outer circumferential section of the head body. CONSTITUTION:The head body 2 is fitted into the cylindrical trunk 1, and after the u...
