Title: Detecting method for field closing rotational frequency of synchronous motor
Inventor: KATOU YUKITOSHI
IPC: H02P1/50
Filed: 1979-12-10
Abstract: PURPOSE:To obtain a field closing for a brushless exciting type synchronous motor at a given rotational frequency by detecting field closing rotational frequency through fluctuation in frequency of an armature input. CONSTITUTION:A fluctuating frequency of a primary input at starting of a synchronous motor is 2sfHz (s: slip, f: power source frequency). Since slip s changes from 1 to 0, it changes near to 120Hz at the time of commencing start and to 0Hz at the time of closing start at a 60Hz power. A rotational frequency can be detected by observing said change, therefore a field closing is obtainable for the brushless exciting type synchronous motor at a given rotational frequncy.

Title: Molding apparatus for terminal connection of power cable
Inventor: YATSUKA TAKESHI
IPC: H02G1/14
Filed: 1995-06-02
Abstract: PURPOSE: To prevent displacement due to resistive force exerted between a cable and a molding tube without need for any other structure, by screwing a fixing flange onto a threaded portion formed on a conductor drawing rod connected with a cable conductor, and securing the fixing flange to the upper flange on the molding tube body. CONSTITUTION: A molding tube body 10 having a heater 11 therein is placed to cover a portion 4 to be molded. A conductor drawing rod 3 has a threaded portion 3a formed on part thereof, and is extended upward through a flange 12 on the molding tube body 10. A fixing flange 6 having a tapped portion formed on the inside surface thereof, is screwed onto the threaded portion 3a. The fixing flange 6 is secured on the bottom face of the upper flange 12 on the molding tube body 10 with bolts 7. This prevents displacement due to resistive force exerted between a cable and the molding tube, and thus obviates any other structure having anchoring force that used to be required.

Title: Yarn cutting detector of sewing machine
Inventor: ISHIKAWA HITOSHI
IPC: D05B51/00
Filed: 1987-06-27
Abstract: PURPOSE: To detect needle thread breakage by integrally swinging a thread guard and a thread take-up spring, providing a projection on a part of the thread guard and engaging the slit part of a photointerrupter to the sensor operation part of a thread take-up lever. CONSTITUTION: At the time of closing a top cover 67, a slide plate 32 is moved through a latch 34, a thread take-up lever 39 is restored by the restoration force of a twist spring 38, the sensor operation part 39b opens the slit part 42a of the photointerrupter and the output becomes continuous Lo. In this case, at the time of starting a sewing machine, the needle thread is pulled up by a needle thread take-up 19 and strained, the thread guard part 39a of the thread take-up lever is pulled, the slit part is shielded and the output becomes Hi. However, since the needle thread take-up immediately loosens the needle thread, the output becomes Lo, and by repeating it, a microcomputer judges that it is during sewing and a main shaft is continuously rotated.  In this case, when the needle thread is cut, since the slit part is kept open and it becomes continuous Lo because the needle thread is not strained, the thread breakage is judged and the main shaft is stopped.

Title: Enameled substrate
Inventor: ITOU MASANORI
IPC: H05K1/05
Filed: 1988-06-30
Abstract: PURPOSE:To provide an enameled crystallized glass substrate for a thermal printer head capable of increasing temperature of a heating element to a desired value at higher speed and with less power, by doping the enamel of the substrate with a specific amount of TiO2 and/or BaTiO3. CONSTITUTION:An enameled crystallized glass substrate has an enabled layer doped with TiO2 and/or BaTiO3 in an amount of 1 to 10% by weight. For example, BaO-MgO-B2O3-SiO2 crystallized glass is doped with said amount of TiO2 and /or BaTiO3 and molten. The melt is ground by a dry ball mill and an isopropyl alcohol wet ball mell until fine glass particles having a size of 2 to 3mum are obtained. Glass frit can be produced in this manner, while the flatness and uniformity of the enamel surface are held and heat conductivity of the enamel layer is decreased substantially. Accordingly, when current is supplied to a heating element, temperature can be increased to a desired value at higher speed and with less power since heat is prevented from being conducted to the metallic substrate.

Title: Clarifier for filthy water
Inventor: KITAO TAKANE
IPC: C02F3/06
Filed: 1980-11-17
Abstract: PURPOSE: To perform clarificartion of filthy water with saved energy consumption without discharging a large amount of excess sludge, by letting organic filthy water  naturally fall down through filter cloth so that the filthy water is filtered and that  organic substances in the filthy water are hydrolyzed and gasified by proliferating action of anaerobic bacteria.  
     CONSTITUTION: A plurality of filter bodies 8, which stretch filter cloth sheets 19 on  their outside surfaces, are located in fixed intervals inside a filtration tank 1, and the  central lower part of each filter body 8 is connected to a filtrate- collecting pipe 9.  Crude water is fed through a pipe 7 into a crude water-receiving vessel 4, and then  through a feed space 2 into a siltering vessel 5. After a certain amount of crude water flows into the vessels, the pipe 7 is sunk under the water and dissolution of O 2  caused  by diffusion in the air is inhibited, to keep the interior of the vessel 1 under an anaerobic atmopshere. Filthy water in the vessel 4, being prevented from contact with the  air, gradually increases the anaerobic atmosphere and fills in the vessel 5. Thereafter,  a filtrate flow rate- control valve 10 is gradually opened, so that the filthy water in  the vessel 5 is filtered by the filter cloth 19 and drained through the pipe 9. On the surface of the filter cloth 9 is formed a large amount of anaerobic bacteria film to clraify the filthy water.

IPC: H01J49/06
Filed: 1987-06-29
Abstract: PURPOSE:To extend the life of a detector and a secondary electron multiplier tube by controlling the scanning voltage applied to a electrode member so that an element with the specific mass contained in a sample does not pass the electrode member. CONSTITUTION:The output of a computer 21 is fed to a controller 22, and the scanning voltage applied to an electrode member 17 from e voltage power source 23 is controlled by the controller 22. The controller 22 also controls the scanning voltage applied to the electrode member 17 from the voltage power source 23 so as to scatter, e.g., water-related ions with masses 16-19 and argon- related ions with masses 40, 41 for scanning. Argon-related ions and water- related ions forming large-background ions do not reach a secondary electron multiplier tube 20. A large current is thereby prevented from flowing in a detec tor or the secondary electron multiplier tube 20, and the life of the detector or the secondary electron multiplier tube can be extended.
