Title: Self-sucking type dual stage turbine pump
Inventor: YOSHIHARA SHIGETOMO
IPC: F04D9/02
Filed: 1980-03-26
Abstract: PURPOSE: To greatly increase self-sucking performance by arranging the top of one of water paths for a retainer second guide vane at the position which is located at the same height as the top of the outer periphery of the first vane or higher and defining the constitution of the water paths.  
     CONSTITUTION: Air and water mixture from an intake is sucked and exhausted to and by the first vane 5 during self-sucking operation of a pump. The mixture is guided to the second vane 22 by the first vane 1. Since one of water paths 51 of the second vane 21 is located approximately higher than the first vane 5, the air in the air water mixture does not stay in a delivery part of the first vane 5, and sucked to the second vane 22. The mixture is delivered into a body 6 in a similar fashion at the delivery side of the second vane 22. Thus, the self-sucking performance can be greatly increased only by defining the water paths.

Title: Drive circuit for electromagnetic head
Inventor: KOBAYASHI TADASHI
IPC: B41J2/30
Filed: 1982-03-12
Abstract: PURPOSE:To reduce power consumption and rise of temperature of the head of an impact dot printer by such an arrangement wherein magnetic energy which is not converted into kinetic energy for the electromagnetic head is converted into electrical energy through a transformer. CONSTITUTION:When a transistor 3 is turned on by a print signal from a control terminal 5, most current flows to a head coil 1-1, since its on time is short and AC impedance of a transformer 6 is fairly large, and a movable piece 1-3 of a head 1 is attracted and a dot is printed by a needle 1-4. Next, at the instant when the transistor 3 is turned off, the exciting current flowing through the coil 1-1 induces a positive voltage in the collector, as it tends to continuously flow, in other words a self induced voltage V is impressed on No.2 winding 6-2 of the transformer 6 and a voltage is also generated in No.1 winding 6-1 corresponding to its winding ratio, and if the voltage is higher than that of a power source, a diode 7 is biased in the normal direction and electricity is returned to a power source side 2. Consequently, power consumption is reduced, the rise of temperature of the head is suppressed and the head can be reduced in size.

Title: Impedance measuring apparatus of power line carrier path
Inventor: WADA MASAMI
IPC: G01R27/14
Filed: 1988-02-19
Abstract: PURPOSE:To obtain a small sized inexpensive apparatus having stable characteristics, by measuring the absolute value of the impedance of a power line carrier path only by one voltage detection means. CONSTITUTION:The constant current AC signal (i) having frequency desired to be measured outputted from a constant current transmitting means 1 is transmitted to a power line carrier path 5 through a coupling means 4 for blocking the invasion of low frequency AC voltage. Since the signal (i) takes a constant value from the relation applying the signal (i) to the equivalent impedance of the carrier path 5 on the basis of the output voltage from the means 1, the absolute value of the voltage detected by a voltage detection means 6 shows the absolute value of the equivalent impedance of the carrier path 5. Hereupon, by processing a predetermined constant by the distribution of the scale of a display means 7, the absolute value of the impedance of the carrier path 5 can be directly read by one means 6.

Inventor: WADA MINORU
IPC: C21C1/02
Filed: 1987-02-20
Abstract: PURPOSE:To inhibit a resulfurization reaction to a minimum during refining with a refining agent for dephosphorizing molten pig iron by making the S content in the refining agent contg. an oxidizing agent and calcium oxide higher than the conventional content. CONSTITUTION:A refining agent for dephosphorizing molten pig iron contains at least an oxidizing agent for oxidizing P in the molten pig iron and calcium oxide for stabilizing a dephosphorized product. The S content in the refining agent is regulated to 0.05-1.0wt.%. Though the S content is higher than the conventional content, a slag-metal reaction does not well proceed during refining in the molten pig iron trough of a blast furnace because of short refining time, so a resulfurization reaction hardly takes place.

Title: Compound semiconductor device
Inventor: IMAMURA KENICHI
IPC: H01L21/331
Filed: 1989-02-20
Abstract: PURPOSE:To make the speed of a device high by constituting the device by laminating an InGaAs collector layer, an InAs basse layer and an InGaAs emitter layer on a semi-indulsting InP substrate or constituting the collector layer of a super lattice comprising InAs/InGaAs. CONSTITUTION:In a compound semiconductor device, an InGaAs collector layer 23, an InAs base layer and an InGaAs emitter layer 25 are laminated and constituted on a semi-insulating InP substrate 21. Otherwise the collector layer 23 is constituted of a super lattice comprising InAs/InGaAs. As a result, the effective mass of the carriers in the base layer 24 is small. Therefore, when the thickness of the base layer 2 is made to be e.g. 100Angstrom , the base running time of the carrier can be shortened to 1/2 and the collector running time can be also shortened to 1/2 in comparison with an InGaAs/InAlAs system. Thus the speed of the device can be made high.
