Title: Continuous casting method for molten metal
Inventor: YOSHIDA TSUTOMU
IPC: B22D11/041
Filed: 1981-03-31
Abstract: PURPOSE:To stabilize the quality of an ingot in the initial period of casting and to improve safety by increasing the casting speed successively according to the length of the ingot formed with a mold until the final steady speed is attacined. CONSTITUTION:When the descending speed (steady speed) of a descending member (mold bottom) 10 with respect to a mold 1 is determined, it is set in a casting speed setter 11. The respective speeds up to the 1st-5th speeds are set in a per cent setter 12. The descending of the member 10 is controlled by a casting machine controller 14 so as to conform to the set value of the 1st speed, and the length of the ingot is measured by detecting the number of revolutions of a DC motor 15 with a tachometer 17. This information is inputted to a casting length setter 13. When the set value is attained at the 1st speed, the device 13 produces an output so as to change over the casting speed in the setter 12 to the 2nd speed, and the motor 15 is controlled by the controller 14, so that the member 10 descends at the 2nd speed. In this way, the speed of the member 10 is increased successively from the 1st speed to the 5th speed until the steady speed is attained, after which the casting is accomplished at the steady speed.

Title: Image forming device
Inventor: HIROSHIMA KOICHI
IPC: G03G15/16
Filed: 1989-02-28
Abstract: PURPOSE:To prevent an image carrier surface from being heavily soiled, which causes image flowing and toner fusing by giving the polishing function of the image carrier surface to a transfer member in a contact transfer system where the transfer member is pressed to the image carrier surface and transferred. CONSTITUTION:The image forming device is designed to ground the surface of a photosensitive drum 1 unless a transfer paper P passes between the drum 1 and a transfer roller 5A in such a way that the surface of the transfer member holds abrasive material or the surface of the transfer member is roughened so as to have a grounding action. That is, a ZnO dispersed EPDM roller, which uses low-priced ZnO and is polished and roughened, is used as the transfer roller 5A. When the transfer paper does not pass between the photosensitive drum 1 and the transfer roller 5A, the transfer roller 5A comes into direct contact with the photosensitive drum 1. Therefore, toner and paper dust, etc., adhering to the photosensitive drum 1 are peeled off and efficiently removed by a cleaning device 6 in the next stage, and then a high quality picture can be outputted for a long period.

Title: Air conditioner
Inventor: TAIRA SHIGEJI
IPC: F25B1/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To widen an application range by setting the length of connecting piping to a specific range, and by filling a hydrofluorocarbon 32-family refigerant. SOLUTION: In the multi-type air conditioner, when the total piping length of connecting piping L2, L3, and L4 is set to 75 meters, the same or larger heating-cooling capability is achieved. The air conditioner can be used without any trouble even when the total piping length is 100 m or less. On the other hand, when the total piping length exceeds 100 m, a HFC 32-family refigerant cannot be properly distributed to indoor machines 2, 3, and 4. When the total piping length is 60-100 m, the air conditioner can be used since the loss of pressure due to piping resistance is smaller than an HCFC 22-family refrigerant that is generally used. The piping diameters of the connecting piping L2, L3, and L4 is set to 1/2 or 3/8 inches, and the piping diameters are the same as or narrower than the piping diameter when the HCFC 22-family refrigerate is used.  In this case, there are no problems also in terms of oil return performance to the compressor.

Title: Semiconductor logic circuit and semiconductor integrated circuit device using it
Inventor: KANEZASHI KAZUYUKI
IPC: H03K19/017
Filed: 1994-03-18
Abstract: PURPOSE:To attain more large driving capacity and high speed, suppressing power consumption by keeping up off-states by first and second switches for a period other than the period till the establishment of the logic of an output terminal because the switches are limitedly turned on for the only period till establishment of the logic of the output terminal. CONSTITUTION:This circuit device has a first switch means 3 interposed between a high potential side power source line 1 and an output terminal 2, a second switch means interposed between the output terminal 2 and a low potential side power source line 4 and a logic signal generation means 6 generating logic signals Sa and Sb, etc. Because the first and second switches are limitedly turned on for only a period till the establishment of the logic of the output terminal 2 and keep up off-states for a period other than the period, a period when the both of the first switch means 3 and the second switch means 5 are turned on does not exist. As a result, through current does not flow at all. Therefore, even if the current capacity of the first switch means 3 and the second switch means 5 is increased, the inconvenience that power consumption is increased is not invited and the power saving is possible.

Title: No-power supply signal generator
Inventor: NOGUCHI YOSHIHARU
IPC: H04R17/00
Filed: 1983-03-23
Abstract: PURPOSE:To obtain a simple and inexpensive no-power supply signal generator with no use of a power supply such as a battery, etc. by using a piezoelectric element as a signal generating source. CONSTITUTION:One pole of a piezoelectric element 1 is earthed 5, and the other pole is connected to a voltage dividing circuit 3. An operation button 2 is used to generate the 1-pulse type voltage from the element 1 and also to apply instantaneously the intensive pressure to the element 1. The 1-pulse type voltage which is produced from the element 1 with operation of the button 2 is applied to an antenna 4 via the circuit 3. Then the antenna 4 radiates the applied divided voltage of the element 1 into the air in the form of signal waves. Thus it is possible to obtain a simple and inexpensive no-power supply signal generator with no use of a power supply such as a battery, etc.

Title: Current transformer
Inventor: SHIGENOBU MASAHIRO
IPC: H02H9/06
Filed: 1978-04-24
Abstract: PURPOSE: To prevent the fault due to the opening of the secondary by providing a non-linear resistor the non-linearity of which is broken by the energy produced when the secondary of current transformer connected in series with the electrode connected between the secondary terminals of current transformer is opened.  
     CONSTITUTION: When the secondary circuit of current transformer 4 is opened, the secondary open voltage V 02  having very high peak is produced. Then the gap 7 begins to discharge to bring substantially shortcircuited state, and said voltage V 02  is suppressed by the characteristic of non-linear resistor 36 below predetermined voltage E z . While when said gap 7 is discharging continuously secondary current i 2 L proportional to the primary current of current transformer 4 flows continuously, thereby the characteristic of non-linear resistor 36 is broken after predetermined time to bring low impedance. This means that the secondary circuit of current transformer is shortcircuited through a low impedance thereby the current transformer 4 is protected from the secondary opening fault.

Title: Permanent-magnet type rotary electric machine
Inventor: MITA MASAHIRO
IPC: H02K1/22
Filed: 1996-03-06
Abstract: PURPOSE: To increase only the effective magnetic flux amount contributing to the generating efficiency in the motor efficiency by employing a member coexisting a ferromagnetic part and a non-magnetic part in a rotor yoke, and disposing the non-magnetic part at the rotor yoke position for causing a leakage magnetic flux. CONSTITUTION: A rotor yoke 65 is made of the laminate of thin plates 67, and formed of a member coexisting a ferromagnetic part 650 and a non- magnetic part 660. A permanent magnet 1 is inserted into a through hole 68, and closely fixed in the yoke 65. Poles N, S of total four poles are formed on the outer periphery of a rotor 10 of the magnet 1. Since the part 660 indicated by a shade is the non-magnetic part, no short-circuit occurs in the magnetic flux in the yoke 65, and hence leakage magnetic flux is extremely small. As a result, the leakage magnetic flux generated between the poles formed at the permanent magnet or between the adjacent magnets can be suppressed, and a rotary electric machine having efficient magnetic circuit can be formed.
