Title: Heating power source device
Inventor: KUMON SEIICHI
IPC: H05B3/00
Filed: 1984-05-22
Abstract: PURPOSE:To obtain a heating power source device without requiring a thyristor of large capacity by supplying a high voltage by connecting in parallel several loads at the time when electric conduction is started, and connecting the loads in series successively as a load current increases. CONSTITUTION:When starting electric conduction, loads 41, 42 require a high voltage low current, therefore, a thyristor unit 2 is turned on, and primary windings 51a, 52a of boosting transformers 51, 52 are conducted. In case of viewing from a power source side, the load 41, 42 become a shape connected in parallel, and a high voltage is applied to these loads. Also, as the load grows and the resistance falls, the thyristor unit 2 dereases a load current by a control signal from a controlling circuit which is not shown in the figure. When the supply voltage drops to a prescribed value determined in advance, the thyristor 2 becomes off, and a thyristor 3 becomes on. In this way, the loads 41, 42 are connected in series to the power source, and a low voltage and a large current are supplied.

Filed: 1984-05-21
Abstract: PURPOSE:To perform logical shift processing in the same route with addition and subtraction processing by providing a bit shifter in a processing stage of addition and subtraction which are processed on a pipeline basis, and making a shift of <=1 digit. CONSTITUTION:When a right logical shift is made by 4N+m bits, a shift is by 4N through a digit matching circuit and the result is stored in a stage register 33. Then, a right shift is made by the remaining (m) bits through a bit shifter (f) and the resulting data is passed through a nomalizing circuit (e) without any shift, so that the result of the desired right logical shift is obtained in a stage register 60. Then, a logical shift by 4N+m bits to left is made similarly through the shifter (f) and the result of the desired left logical shift is obtained in the register 60. Thus, the filter (f) is added in the arithmetic pipeline stage and a shift of <=1 digit is made to perform logical shift processing in the same route with addition/subtraction processing.

IPC: C09D11/00
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a water-based ink composition which is free from a rapid viscosity increase because of its good slow-drying properties and does not emit a strong odor and which neither blots a recorded image on a thermal recording paper or noncarbon paper nor suffers a color change, even when applied on a thermal recording paper, by incorporating a specific compound into a water- based ink. CONSTITUTION:This composition comprises a mixture of a water-based ink containing a colorant and water with at least one member selected from pentaerythritol, trimethylolethane, and trimethylolpropane. In the case where the composition is a dye ink, it is produced by mixing and dissolving the ingredients under stirring. In the case of a pigment ink, the composition can easily be obtained by treating the ingredients with an ordinary dispersion mixer, e.g. a ball mill, for mixing, grinding, and dispersion, or mixing the ingredients with a known stirrer, followed if necessary by the removal of coarse pigment particles by filtration or centrifugal separation.

Filed: 1992-03-30
Abstract: PURPOSE:To identify an internal partial discharge pulse and an external partial discharge pulse and improved measurement reliability by detecting noise at a higher-level part near a noise-generation source and comparing it with a signal which is detected at a cable part. CONSTITUTION:When a partial discharge is generated in an air transmission line 5, the corona and external noise are propagated to an inducing cable 3 which is laid within an underground conduit 12. Since a power cable 2 within the underground conduit 12 is in parallel with the cable 3, external noise from the cable 3 is induced. At this time, a partial discharge is detected through an impedance Zs 7 by a partial discharge detection electrode 6 and external noise is also detected. Then, an external noise detection electrode 13 is provided at a position near an inducing source of the cable 3 and external noise is detected through an impedance Zn 8. Both signals are lead to a discriminator 11 and a signal S of an amplifier 9 and a signal N of an amplifier 10 are compared. Then, when the signal level N is larger than the signal level S, it is judged to be the external noise.
