Title: Controller for electric rolling stock
Inventor: NIREHARA HIDEKI
IPC: B60L15/28
Filed: 1988-03-09
Abstract: PURPOSE:To obtain a small-size and inexpensive controller for an electric rolling stock by correcting a conduction rate when a conduction rate change ratio exceeds a predetermined value. CONSTITUTION:A current pattern generator 9 generates a current pattern IP equivalent to the torques generated from DC motors 1 and 2. A subtractor 10 outputs the difference between the pattern IP and a correction signal A as a correction current pattern IP'. A conduction rate calculator 11 calculates the conduction rate (r) of a chopper 7 on the basis of a motor current IM and the pattern IP'. On the other hand, a limiter 6A outputs the signal A by judging an idle or a slide when the change rate  gamma of the conduction rate gamma detected by a differentiator 12 exceeds a predetermined value. Thus, a small-sized, inexpensive controller for an electric rolling stock can be obtained.

Title: Electrophotographic device
Inventor: MATSUO KAZUYOSHI
IPC: G05D23/19
Filed: 1995-03-14
Abstract: PURPOSE: To improve accuracy for controlling a fixing temperature and to make an image quality stable by predicting a state before inputting of a power source from the surface temperature state of a fixing roller, a stored content and a temperature increase time and determining a control method immediately after inputting of power based on the prediction. CONSTITUTION: A fixation device control circuit stores a plurality of control points T1 to T6 with specified temperatures allocated thereto by a CPU 14 and controls a heating means at a control point T4 mainly while a temperature in a machine is stable. However, since the surface temperature of a fixing roller becomes high immediately after this is started when switching on/off of heating means 16 and 17 is controlled only at this control point in an unstable region, a roller surface temperature is made stable by switching a control point to T3 and T4 in the unstable region. For corrections by switching among the control points T1 to T6 in stages, control is performed by determining the operational state of the device thus far, that is, a control point from a state before inputting of power and a current temperature state.  For example, when a state is lower than T1 in the case of turning a power source on, a state before inputting of power is predicted by calculating a temperature increase time until T2.

Title: Method for controlling delivery of blast furnace charge material
Inventor: ONODA DAISUKE
IPC: C21B5/00
Filed: 1991-02-26
Abstract: PURPOSE:To improve the accuracy in controlling the delivery rate of the blast furnace charge materials or the accuracy in controlling the time to stop or start the delivery of the materials. CONSTITUTION:The relation between the characteristic of the quantitative material feeding means and the characteristic in the material delivery of a delivery gate is previously obtained as the material delivery correction characteristic in the calculation 30 of the correction value for the opening degree of the delivery gate. When the quantitative material feeding characteristic is changed, the characteristic in controlling the opening degree of the delivery gate is corrected to the actual material delivery in the calculation 60 of the material delivery characteristic. The data of the actual value collection 160 are used for the calculations 30 and 60. The opening degree of the delivery gate matching the actual value is set in this way.

Title: Mixer feeder container
Inventor: GERUHARUTO HETSUPENSHIYUTEIIRU
IPC: B41F31/02
Filed: 1986-03-12
Abstract: A mixer-feeder vessel for the percentagewise mixing of two or more liquids, particularly for offset printing presses, enables a fluid contained in the feeder vessel to be admitted to a fluid tank. A partial volume of the mixer-feeder vessel is subdivided into a predetermined number of chambers by means of partition walls, with the chambers arranged in adjacent relationship to form a row. The partition walls protrude from one wall of the vessel by a predetermined length into the vessel. In a wall opposite the one wall of the vessel there is provided an inlet-outlet port aligned with a first chamber of the row of chambers, so that when a liquid is supplied through the inlet-outlet port, the first chamber situated under the port is first filled and subsequently the remaining chambers along the row are filled in series. The opposite wall is spaced from confronting end sections of the partition walls by another length.

Title: Biological activated carbon treatment apparatus
Inventor: ISHIKAWA KATSUHIRO
IPC: C02F1/28
Filed: 1989-03-07
Abstract: PURPOSE:To improve operational efficiency and keep cleaning capacity for a long period by installing a water dispersing apparatus to spray stirring water toward a surface area of a biological activated carbon in an upper part of a treatment tank. CONSTITUTION:Water to be treated which flows to a treatment tank 1 from an upper part is cleaned with a biological activated carbon 2 and then sent to the next treatment. A dispersing apparatus 17 connected to a stirring water supplying pipe 15 is installed in an upper part of the biological activated carbon 2 in the treatment tank 1. The dispersing apparatus 17 has a nozzle to spray stirring water upward and stirring water sprayed from the nozzle stirs suspensions deposited on the surface area of the biological activated carbon 2. As a result, with stopping introducing water to be treated, the pressure loss of the biological activated carbon 2 is recovered and thus operational efficiency of the apparatus can be improved and at the same time, the numbers of reverse cleaning can be remarkably decreased and cleaning capacity is maintained for a long period.

Title: Frequency modulator
Inventor: AKAIWA YOSHIHIKO
IPC: H04L27/20
Filed: 1979-05-04
Abstract: PURPOSE:To reduce the variation of phase of modulated waves, by setting the initial value of the integrator in synchronizing with the input digital signal with the output in response to the input digital signal up to now and preventing the storage of integrated error. CONSTITUTION:The signal at the input terminal 41 is branched into two; one is input to the integrator 44 via the filter 43 to synchronize with the clock signal fed to the terminal 42 and to reset the initial value of the integration into zero. Another is in synchronizing with the clock signal to produce a given voltage within a given time, and this voltage value is fed to the circuit 45 which changes the value in response to the input digital signal fed up to now. Further, by using the signal adding the output of the integrator 44 with the output of the ciruit 45, phase modulation is made at the phase modulator 47. Accordingly, since the initial value of the integrator 44 is set with the output of the digital circuit 45, the error of integration can not be stored.

Title: Magneto-optical recording medium, magneto-optical recording method, magneto-optical erasing method, and magneto-optical recording and reproducing device
Inventor: MIYAOKA YASUYUKI
IPC: G11B11/10
Filed: 1989-03-09
Abstract: PURPOSE:To thin a device by laminating two magnetic layers respectively having a specific Curie point and room temperature coercive force, setting up the magnetization of both the magnetic layers in the stable direction of magnetization and using one of the magnetic layer as an auxiliary magnetic field forming layer and the other as a recording layer. CONSTITUTION:The recording layer 33 has a low Curie point and high coercive force at a room temperature and the auxiliary magnetic field forming layer 30 has a Curie point higher than that of the layer 33 and low coercive force at the room temperature. When magnetic field intensity Hb for inverting only the magnetization of the layer 30 by a bias magnetic field head 7 in an erasing state e.g. is impressed in the shown arrow direction, only the magnetization of the layer 30 is inverted and a recordably state is set up. When the surface of the layer 33 is irradiated with a laser beam modulated by an information signal and the laser beam is condensed thereon, only the laser 33 reaches the Curie point, and in a process reducing the temperature from the Curie point, the direction of the magnetization is reversed from that of the erasing state and recording can be executed. Consequently, it becomes unnecessary to arrange the bias magnetic field head 7 oppositely to the optical head 3 and the device can be thinned.
