Title: Manufacture of electrode plate for lead-acid battery
Inventor: TAKAHASHI KATSUHIRO
IPC: H01M4/14
Filed: 1987-06-19
Abstract: PURPOSE:To prevent the deterioration in the lifetime of a battery by using a kind of paste mixed and kneaded mainly with lead powder containing lead oxide of specified fraction of minium and water and sulfuric acid. CONSTITUTION:A kind of paste mixed and kneaded mainly with lead powder containing lead oxide of minium fraction of less than 90% and water and sulfuric acid is used for the electrode. It is more desirable to keep the minium fraction less than 70%, and to use a lead oxide in which lower degree oxide reactive on sulfuric acid and water and generating bonding force when the paste is kneaded is reserved while being combined with minium. Thereby the efficiency in conversion process can be improved and also the lifetime can be elongated.

Filed: 1990-06-12
Abstract: PURPOSE:To attain uniformity in quality and raise work efficiency by providing a means for making sewing action consecutively after dividing a sewing area into plural positions previously to freely set auxiliary feed quantities in response to various kinds of sewing. CONSTITUTION:A drive mechanism for driving stepwise an auxiliary feed mechanism is connected to said auxiliary feed mechanism. There is provided a means for dividing a sewing area into plural positions previously to make sewing action consecutively. There is also provided a means for controlling the drive quantity of the auxiliary feed mechanism by the above-mentioned drive mechanism at the respective divided positions and setting the auxiliary feed quantities in plural steps, and in the similar way, there is provided a cloth feed quantity-control device in the respective divided positions while providing possibility for selecting non-operation where shifting to the next position automatically takes place. An auxiliary feed quantity suitable for a sewing area is set arbitrarily in the respective divided positions to consecutively and also no-operation is selected at respective positions, the sewing action automatically shifts to a next position. Consequently, the number of division is substantially reduced, and thus the sewing action is conducted by setting arbitrarily the number of division, i.e., the number of sewing steps, in conformity to the purpose of sewing.

Title: Method and device for intercepting light and light transmission line system
Inventor: KANAI TATSUO
IPC: H04B10/296
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive abnormal signal from a slave station from having an influence upon the access of other slave stations by absorbing a part of transmitted light by an absorption phase to generate heat and raising the temperature of a polymer phase and causing the phase change of liquid crystal to reduce the transmittance of light. SOLUTION: Light intercepting devices 3 to 5 are set between a star coupler 2 and slave stations 6 to 8. In light intercepting devices 3 to 5, a part of transmitted light is absorbed in an absorption phase to generate heat. This heat generation is proportional to an average optical power transmitted through light intercepting device 3 to 5, and the temperature rise of the polymer phase is also proportional to the average optical power. Liquid crystal in the polymer phase used here is so selected that its transmittance is not affected by the temperature rise due to the average optical power in the normal communication state but is reduced by the phase change of liquid crystal in the case of the higher temperature rise. Consequently, an abnormal optical signal due to faulty slave stations 6 to 8 can be controlled by the change of the polymer phase.

Title: Ultrasonic flaw inspection for electric welded stainless steel pipe
Inventor: KIMURA TSUTOMU
IPC: G01N29/22
Filed: 1984-07-26
Abstract: PURPOSE:To inhibit the generation of a noise echo in the ultrasonic flaw inspection, by having an austenite based electric welded stainless steel pipe subjected to a heat treatment process of heating it above 850 deg.C upto 1,350 deg.C and cooling.

Title: Off-shore platform
Inventor: TOMONAGA KENROU
IPC: E02B17/00
Filed: 1980-11-02
Abstract: PURPOSE: To facilitate miniaturizing of a temperature of crude oil in an oil storage tank and to enable a tanker to easily come alongside the berth, by a method wherein a sand ballast chamber is installed between a square outer peripheral wall and a storage tank having a circular section.  
     CONSTITUTION: An off-shore platform 10 consists of an underwater structure part having a square outer periphery wall 11a, pillars 12, and a deck 13. The bottom of the underwater structure part is of a double shell bottom 14. A space between a storage tank 15 and a structure wall 18 is thermally insulated. The platform 10 is tugged, water is poured at an installation spot to seat it on the bottom of the sea E, and a sand ballast chamber 21 is filled with sand. The adjustment of an amount of sand, wherewith the sand ballast chamber 21 is filled, permits the platform 10 to seat on the bottom of the sea even if the storage tank 15 becomes empty. This eliminates the need for the replacement of oil with water and facilitates maintaining of a crude oil temperature. Additionally, the formation in a square of the outer peripheral wall 11a enables a tanker to easily come alongise a berth.

Filed: 1999-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a nail dermatophytosis-treating preparation which comprises a dermatophytosis-treating medicine to be coated on an affected site and a coating agent for protecting the medicine from its peeling and dissolution in water. SOLUTION: A coating agent is coated on an applied dermatophytosis treating medicine so that the dermatophytosis-treating medicine is not rubbed out or dissolved off from the surface of a nail. The nail invaded by dermatophytosis is coated with the dermatophytosis-treating medicine, dried, and further coated with the coating agent, followed by curing the coated coating agent. Thus, the first coated dermatophytosis-treating medicine can perfectly be protected so as not to be rubbed out or dissolved in water. An instantaneous adhesive is used as the coating agent. Thereby, the coated dermatophytosis-treating medicine stays for a relatively long period to facilitate the treatment of the dermatophytosis, without removed during bathing or by footgear.

Title: Voltage converting circuit
Inventor: SAKURAGI SATOSHI
IPC: H02M3/00
Filed: 1994-07-06
Abstract: PURPOSE:To obtain a voltage converting circuit which operates with low power consumption without being affected by an input DC voltage. CONSTITUTION:At the start of operation, a single-chip CPU 1 turns ON a transistor(TR) switch 4 and a three-terminal regulator 2 converts the input DC voltage Vo (3 or 5V) into an output DC voltage Vcc (3V). Then when the input DC voltage Vo is 3V, the single-chip CPU 1 continues this state. When the input DC voltage Vo is 5V, on the other hand, the single-chip CPU 1 turns ON a TR switch 6 and turns OFF the TR 4 and a step down DC-DC converter 5 converts the input DC voltage Vo (5V) into the output DC voltage Vcc (3V). According to the input DC voltage, the three-terminal regulator 2 or step-down DC-DC converter 5 which has relatively small loss is selected and placed in operation, so the power consumption is reduced. This circuit is useful, specially, as a voltage converting circuit incorporated in a modem device which is supplied with electric power from a battery-driven type portable terminal.
