IPC: H02K41/03
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a linear motor which is suitable for a chip mounter, etc. SOLUTION: A field 50 on a stator side is divided into a plurality of sections (areas A-C) in the direction of the movement of an armature. The lengths (dimensions in a Y-direction) of permanent magnets 51-53 are made different from each other, i.e., the permanent magnets 51 in the area A are longest, the permanent magnets 53 in the areas C are shortest and the permanent magnets 52 in the areas B have medium length. With this constitution, the coil of the armature crosses the largest fluxes generated by the permanent magnets in the area A, with the medium fluxes in the areas B and with the smallest fluxes in the areas C. As a result, the magnitude of a generated thrust force is largest in the area A and reduced in the areas B and in the areas C in this order.

IPC: H03F1/52
Filed: 1987-05-26
Abstract: PURPOSE:To eliminate the need for an electrical reflected wave detecting function, to lower a price, and to miniaturize the titled device, by detecting a reflected power by detecting the temperature rise of a dummy load, and cutting off an amplifier when abnormal temperature rise occurs. CONSTITUTION:In a high frequency/high output amplifier, the amplifier 10, a circulator 12 connected to the output terminal of the amplifier, the dummy load 14 for absorbing the reflected power connected to the circulator, and a temperature detector 24 to detect the temperature of the dummy load are provided. When a large reflected power exists, the temperature of the dummy load 14 rises, and the detector 24 detects the fact, and sends a temperature signal to a power source circuit 22, and the power source circuit 22 cuts off a power to be supplied to the amplifier part 10 when the temperature of the dummy load exceeds a prescribed value. Therefore, since the dummy load 14 receives no reflected power hereafter, no high power-resistance of the dummy load is required. Also, it is not required to provide a directional coupler and a detector as in a conventional device.

Title: Method and device for determining stopping position of slab in vertical rolling mill
Inventor: TERAKADO RIYOUJI
IPC: B21B1/02
Filed: 1981-08-18
Abstract: PURPOSE:To prevent the generation of fish tails and broadside tinning-down in the end  parts of slabs in the stage of middle rolling of continuously cast slabs with hot strip  mills having a vertical scale breaker by subjecting the end parts of the slabs to broadside screwing down with the vertical rolls which are held stopped. CONSTITUTION:In the stage of producing hot strips of various widths from a continuously cast slab of a specified width, the slab is subjected to descaling and rolling for  the purpose of width adjustment with vertical rolls of vertical rolling mills. Here, fishtails of a recessing shape and the parts of a narrow width are usually produced in  the preceding and succeeding ends of the slab, and are required to be cut away before  the slab is fed to finishing mills, due to which the yield of the material is decreased considerably. To prevent such decrease, in the stage of broadside rolling of the slab  with the vertical rolls, broadside screwing-down is applied to the end parts of the slab  with the vertical rolls which are held stopped, whereby the preceding and succeeding  ends of the slabs are formed to the sections of a dogbone shape similar to the shape in  the central part. There is no need for cutting the preceding and succeeding end parts  of the slab, and the slab is rolled to a hot strip in higher yields.

IPC: G11B7/09
Filed: 1986-06-04
Abstract: PURPOSE:To always attain stable tracking against various external disturbances by adding a proper signal from a signal generator to an amplifier in a tracking servo loop to automatically adjust the tracking servo characteristic based on the result of detection of an external disturbance. CONSTITUTION:In applying an external disturbance such as vibration, a flaw/ vibration discrimination circuit 32 and a selection circuit 23 throw a switch 22 to the position of a contact (b) and an output of preamplifiers 13, 14 for tracking control and an output of a differential amplifier 15 are summed at the input of the differential amplifier 15 as a proper same polar signal. Thus, the tracking error signal becomes larger apparently and the servo gain is strengthened. If a flaw exits, the flaw/vibration discrimination circuit 32 and the selection circuit throw the switch 22 to the position of a contact (c) and the output of the preamplifiers 13, 14 for tracking control and the output of the differential amplifier 15 are added at the input of the differential amplifier 15 as an opposite polarity signal. Thus, the state is close to the conventional operation and out-of-spot from the track is eliminated.
