Title: Start controller for motor
Inventor: SHIRAISHI KAZUO
IPC: H02P1/58
Filed: 1979-04-05
Abstract: PURPOSE:To reduce a voltage drop in starting and diminish the capacity of a power source, by sequentially starting a plurality of motors when power is restored after power failure during the operation of the motors. CONSTITUTION:When power is restored after power failure during the operation of a plurality of motors, a voltage relay E is energized and a contact ea is closed and a timer T1 is energized. After a prescribed time, a timing contact t1 is closed, a relay Y1 is energized and a contact Ya1 is closed. As a result, contacts ga1, ya1 coupled in parallel with a contact xb1 are both closed, a contact eb1 is also closed and a relay X1 is energized to drive a motor M1. When a contact xf1 is closed by the energization of the relay X1, a timer T2 is energized. After a prescribed limit time, a contact t2 is closed and a relay Y2 is energized. As a result, a contact ya2 is closed and a relay X2 is energized to drive a motor M2. The other motors are also sequentially driven in the same manner.

Title: Emulation system for software instruction
Inventor: BABA SEIJI
IPC: G06F9/22
Filed: 1990-02-21
Abstract: PURPOSE:To evade the wrong segmentation of the emulation information and at the same time to prevent the deterioration in the working of an emulator by providing an emulation information storing part where the segmented emula tion information is held and also the contents of the emulation information can be optionally changed by a microinstruction. CONSTITUTION:The software instruction to be executed next is prefetched during the emulation of a software instruction, and the emulation information on the software instruction is segmented and held in an emulation information storing part 4. When the wrong segmentation of the emulation information is detected, the emulation information stored in the part 4 is rewritten by the microinstruction that is given to an emulation information segmenting part 3 from a control storage part 2 and constitute an evading routine. Thus the wrong segmentation of the information can be evaded and simultaneously it is not required to hold the software instruction in a current instruction storing part 1 since the emulation information is held at the part 4. Thus, the working speed is increased in this emulation system for software instructions.

Title: Magnetic recording and reproducing device
Inventor: OGATA HARUKI
IPC: G11B5/008
Filed: 1985-03-04
Abstract: PURPOSE:To reproduce normally plural signals with coincidence of time secured by providing the rotary magnetic heads having different levels of height in the circumferential direction of a rotary drum with shifts secured mutually and adding a delay circuit which produces a time delay equivalent to a circumferential shift amount within the signal recording and reproducing systems. CONSTITUTION:The rotary heads C1 and C2 scan alternately tracks TCn, TCn+1... for production of continuous frequency division multiplex signals (h) which are applied to band pass filters 65 and 66 and then separated into different frequency modulated color difference signals. While rotary magnetic heads Y1 and Y2 scan alternately tracks TYn, TYn+1... for production the continuous luminance signals (i) at the output sides of a reproduction preamplifier 73 and an FM demodulator 74 which are delayed by a delay circuit 51 by a fixed time. Thus the color difference signal is coincident with the luminance signal in terms of time. Furthermore no mutual interference is produced between heads C1 and Y1 since they are separate from each other in the circumferential direction of a rotary drum 14. Thus these magnetic heads have stable contacts with a magnetic tape 15 and therefore the recording/reproduction characteristics are never deteriorated.

Title: Mixing of positive mixture for battery
Inventor: IWAMARU FUTAYASU
IPC: H01M4/04
Filed: 1980-04-01
Abstract: PURPOSE:To enable even acetylene black or the like which is contained in a positive mixture to be evenly mixed, by mixing the mixture through the rotation of an upper ribbon vane and a lower diffusion blade which are installed within the mixing vessel of a mixing machine. CONSTITUTION:A fixed seald mixing vessel body 1 has a material pouring port 2 in its top and a mixture exhaust port 3 in its bottom. A revolving body consisting of a revolving shaft 6 and a ribbon vane 10 attached to the shaft 6 is installed in the upper part of the vessel body 1. A columnar diffusion blade 11 consisting of a revolving shaft 7 and prismlike projections 12 provided on the round surface of the shaft 7 is installed in the lower part of the vessel body 1. The ribbon vane 10 is rotated at a rotating speed of 30-500rpm, while the diffusion blade 11 is rotated at a rotating speed of 500-1,500rpm, in order to make a positive mixture to be mixed. Owing to the above constitution, the positive mixture can be finely mixed in a short time with high efficiency, and the difference in specific gravity between an active material and a conductive agent has only a little influence on the mixing of the positive mixture. Besides, the aggregation of any chain-structure substance such as acetylene black can be properly unfastened, and thereby the positive mixture can be evenly mixed.

Title: Reset signal generating circuit and power unit
Inventor: SAKO KENICHI
IPC: H02M7/06
Filed: 1989-02-22
Abstract: PURPOSE:To eliminate a time change to be caused for a period from the interruption of the power voltage to a reset signal is outputted by using a Zener diode which controls the output voltage of an integrating circuit down to a prescribed level or less. CONSTITUTION:The averaged voltage applied to a comparison means 31 is limited down to a prescribed level or less by the Zener diodes 4 - 6. Therefore, the output voltage of an integrating circuit 9 is fixed at a prescribed level in a power supply state despite some difference of the level of the power voltage and the working state of an equipment which are used at the relevant time point. Then the output voltage of the circuit 9 is always reduced along a prescribed reduction curve when the power voltage is interrupted. As a result, no time change is caused for a period when the output voltage of the circuit 9 reaches the reference voltage level of the means 31 from the start of reduction of the output voltage.

Title: Reforming of converter refining slag
Inventor: KITAMURA MINORU
IPC: F27D15/00
Filed: 1978-04-10
Abstract: PURPOSE:To reduce trouble with molten slag, stabilize the components of molten metal, raise the yield of alloying elements, and lengthen the life of ladle refractory by reforming the molten slag by adding free carbon-containing SiC when or after taking steel out of converter. CONSTITUTION:SiC containing 3 to 15% free carbon is added to molten metal when or after taking steel out of converter, whereupon SiC is decomposed into Si and C which are dissolved in steel on the one hand and also reacted with O present in steel to remove acid on the other. The SiO2 formed from the reactions Si + O  (SiO2) and C + O CO buoys up to form slag, while CO also buoys up in the form of bubbles to make the slag porous. And, C formed by the decompositon of SiC and the free C are dissolved in steel to contribute the removal of acids, while the remainder buoys up and reacts with the converter slag to reduce FeO present in the slag. Thus, FeO, which is the most harmful component consuming the alloying elements in molten steel by the reaction FeO + C Fe + CO, can be reduced. Furthermore, the reactivity of the slag can be greatly reduced and the life of ladle refractory can be lengthened.
