IPC: H04Q3/545
Filed: 1991-02-27
Abstract: PURPOSE:To select a connection destination circuit from an optimum route by revising properly routing information when relay lines are in congestion in the exchange accommodating the plural relay lines. CONSTITUTION:When congestion takes place in, e.g. a relay line A, a congestion detection section 22 of a control section 2 detects it and congestion information is informed to a call control section 20. Upon the receipt of the information, the call control section 20 requests the selection of an optimum bypass route to an optimum route decision section 23, a data base provided in the inside of the decision section 23 is driven to decide a substitute relay line and it is informed to the call control section 20 that the optimum relay line is B. Upon the receipt of the notice, the control section 20 makes a request of it to a table revision section 24 that routing information in a routing table 21 using a trunk circuit 5 accommodating the relay line A is used for the connection destination is rewritten and the information is rewritten into the trunk circuit 6 accommodating the substitute relay line B. Thus, a setup required time at congestion is reduced.

Title: Control method for gaseous pressure in hood in converter gas treating device
Inventor: ENOMOTO MASAYUKI
IPC: F27D17/00
Filed: 1980-06-09
Abstract: PURPOSE:To obtain a converter gas of good rates of recovery by controlling flow rates in the initial and end periods of blowing and automatically controlling pressure when the gaseous pressure in a hood attains a set pressure. CONSTITUTION:Upon lapse of a constant time after the start of blowing, a contact 15 changes over to the side (a), and a set drop signal enters a program setter 14. The output of the setter 14 drops at the rate having been preset from the gas flow rate value of that time, and the output of a flow rate controller 13 drops as well. The output of this controller 13 is sent to a damper actuator 12, by which a damper 15 is closed and controlling of flow rates is accomplished. When the gaseous pressure in the hood attains the preset value in a due course of time, a contact 11 changes to the side (a) and the value detected by a gaseous pressure detector 7 enters a pressure controller 10, where the deviation from an internally set value is subjected to PI operation and is sent to a damper actuator 12, by which the opening degree of the damper 5 is controlled and the gaseous pressure is thus controlled. In the end period of the blowing, a set boosting signal enters the setter 14, and the flow rate controlling is accomplished.

IPC: G11B27/19
Filed: 1985-04-12
Abstract: PURPOSE:To perform an advantageous speed change reproduction capable of retrieving a video track effectively and using a movable head by doubling the number of pulses of a control signal and corresponding the pulse to the video track in a ratio of 1:1. CONSTITUTION:A control signal detected by a magnetic head and inputted from a terminal 1 is amplified 2 and thereafter a waveform shaping is adjusted 3 to be a pulse like reproducing control signal A and inputted to an counting circuit 5 and an OR circuit. The counting D data of an output of the circuit 5 is inputted to a comparator 6. The comparator 6 outputs a pulse like delay control signal E only when a value of the data D is a reference value and the signal E is inputted to a circuit 7. The circuit 7 obtains the logical OR of the signals A, E and outputs a doubler control signal F. Thereby, one control pulse can effectively retrieve the video track corresponding to one video track.

Title: Method for efficiently producing bacterium parasitizing in nematode
Inventor: KAWADA HIROSHI
IPC: A01N63/00
Filed: 1994-03-25
Abstract: PURPOSE:To effectively produce Pasteuria bacteria parasitizing in plant-parasitizing nematodes by recovering a plant containing the Pasteuria bacteria before the microorganisms are matured, and subsequently maturing the microorganisms, and control the plant-parasitizing nematodes giving damages to crops with the produced absolute parasitizing bacteria. CONSTITUTION:A plant containing Pasteuria bacteria parasitizing in plant-parasitizing nematodes are recovered before the microorganisms are matured. The microorganisms are subsequently matured, while the plant is held in a humidity and a temperature which are not kill the plant. Thus, the absolute parasitizing bacteria which are the enemies of the nematodes are obtained. The bacteria are used for controlling nematodes parasitizing in plants. The plant recovered by the method is stored in a small container, and subsequently used for a plant requiring a wide area, thus enabling the shortage of a period required for the culture of the plant and the effective utilization of the area. For example, either of solanacous plant, leguminous plant, cucurbitaceous plant and malvaceous plant may be used as the plant, but the solamnaceous plant and the leguminous plant are especially excellent. The parasitizing site of the nematode is generally a root part, but the nematode can be palasitized also in the stem and leave. When this microorganism is multiplied only in the root part, the stem and leaf parts can be cut off at the ground side part of the plant to reduce the volume of the plant.

Relays X1, X2 are connected between 2 phases of fan motor FM side of the contacts M1A, M2A and one phase of power supply side while the normally closed contacts of these relays are connected in series to the exciting circuits of both magnet switches. When fusion welding is generated in either one of the contacts M1A, M2A, the exciting circuits of the magnet switches are turned off by the normally closed contacts of the relays X1, X2 whereby the connected condition of the contact of the other magnet switch is prevented.

Abstract: PURPOSE:To keep the spacing of a base compensation region for an emitter region and a collector region and to reduce a device by a method wherein polysilicon is formed as a hemisphere-shaped structure. CONSTITUTION:A hole, in an oxide film 8, whose opening end at the oxide film is sphere-shaped is formed by a wet etching operation or an isotropic dry etching operation. Then, P-type impurities at a low concentration are injected in order to form an active base region 9. Then, polycrystalline silicon 7 is deposited; in addition, a resist 16 is coated; the resist 16 and the polycrystalline silicon 7 are etched back by a dry etching operation; the polycrystalline silicon 7 is formed to be hemisphere-shaped directly abobe an emitter region and a collector region. Since the polycrystalline silicon 7 is hemisphere-shaped, an oxide film 11 is left on the sidewall of the polycrystalline silicon when the CVD oxide film 8 is etched back. In addition, the polycrystalline silicon 7 is oxidized by an emitter driving treatment. Thereby, it is possible to keep the spacing of a base compensation region for the emitter region and the collector region.
