Title: Smoke protecting circuit
Inventor: WATANUKI SEIJI
IPC: H04N3/18
Filed: 1987-04-03
Abstract: PURPOSE:To stop the action of an FBT without fail even when the trouble of the FBT occurs while a screen is dark by changing the action point of the smoke preventing circuit of the FBT with the value of a secondary side high voltage output current. CONSTITUTION:An FBT primary take up current flows at a resistance 3. When a current is increased, the voltage drop of the resistance 3 is increased, the base voltage of a transistor 14 falls and at the time of VBE=0.7V or above of the transistor 14, it is turned on. Thus, the action of a horizontal oscillating output circuit is stopped. When a screen is dark, the current flows from a +B power source through a resistance 19 and a diode 20 to +12V and the connecting point potential of a resistance 6 and a resistance 7 goes to 12.7V. When the screen is bright, the current flows in accordance with the brightness of a resistance 6 and the voltage of a capacitor 21 is decreased from 12.7V. For this reason, the transistor 14 is hard to turn on.

Title: Magnetic brush developing method
Inventor: YAMASHITA KEITAROU
IPC: G03G15/09
Filed: 1979-06-27
Abstract: PURPOSE: To make possible the stable development by a magnetic brush even at the high speed developing by making the values of the specified relations among the magnetic flux density, number of magnetic poles and number of revolutions of a permanent magnet roll and the thickness and conductivity of a nonmagnetic sleeve less than the specified values.  
     CONSTITUTION: The nonmagnetic sleeve evolves heat by the eddy current by the magnetic flux of the permanent magnet roll. This temperature rise is higher with the higher speed printer. When toners are subjected to exposure at ≥50° for long, they cause solidification to the sleeve or the like and degrade image quality. Here, when the conductivity of the sleeve is let σ, the thickness t, the number of revolution of the magnet n, the magnetic flux density B and the number of magnetic poles N, the parameter P shown by formula (1) is an important factor that affects the temperature rise. From the figure, keeping the heat evolution at 60°C or less necessitates making the value of P≤10 12 . If within this range, the development may be done without any problem by the magnetic brush even at the high-speed developing.

Title: Superconducting magnet device
Inventor: NAKAO HIROYUKI
IPC: H01F6/00
Filed: 1990-03-30
Abstract: PURPOSE:To permit heat shrinkage between coil inner vessels to prevent relative vibration, and to improve reliability by a method wherein between each of the adjacently positioned coil inner vessels is not restricted in the direction of heat shrinkage, whereas its right-left mutual shifting is restricted. CONSTITUTION:When the force, with which a superconducting magnet device is relatively moved toward coil inner vessels 2a and 2b in right and left directions in the state wherein the magnet device is mounted on a vehicle, works on a link-coupling device 7, the above-mentioned work is impeded because links 8a and 8b are coupled by a link 10, and the relative movement of both links is restrained. However, when above-mentioned moving force worked in the thermal contraction direction between each of the coil inner vessels 2a and 2b, and the direction of arrangement of the coil inner vessels 2a and 2b, the link 10 rotates in an inclining manner, and the movement of the links 8a and 8b is not restrained. As a result, the variation of magnetic field between each of the coil inner vessels can be reduced, mechanical mutual movement is decreased, the breakage of a piping is prevented, and a superconducting coil can be stabilized.

Title: Mach-zehnder device and manufacture thereof
Inventor: UIRIAMU JIEIMUZU MIRAA
IPC: G02B6/28
Filed: 1994-03-29
Abstract: PURPOSE: To provide a monolithic Mach-Zehnder device stable in environment. CONSTITUTION: This device is formed by passing first and second dissimilar optical fibers 16 and 17 through a hole 18 of a glass tube. The tube is deaerated, heated, and collapsed to the fibers. The tube is further heated and extended at two separated positions for forming two couplers 11 and 12 connected with the two optical fibers. The fibers are provided with different propagation constants in an area between those two couplers 11 and 12. Thus, an optical signal propagation through one fiber can have delay relative to the optical signal propagating through the other fiber.

Title: Electric shock preventive device for electrostatic energization type welding machine
Inventor: SUKAI TADAO
IPC: B23K9/10
Filed: 1983-05-10
Abstract: PURPOSE:To prevent the supply of the potential of a capacitor to an output terminal and to prevent the accident, by forming a circuit which interrupts the charging circuit for the capacitor and discharges the residual charge thereof when a detection circuit for continuity breakdown of a thyristor operates. CONSTITUTION:A power source switch 2 is closed to energize a relay 3 thereby closing its contacts 3a, 3b and opening its contacts 3c. If a thyristor 7 is normal in this stage, an input breaker 13 does not operate and therefore the contacts 13a are held closed and a thyristor 6 for opening and closing a charging circuit is turned on, thereby charging a capacitor 5. The thyristor 7 is conducted when the charging potential attains a set value, then the discharging current is instantaneously flowed through a base material 8 and an electrode 9 to complete the operation. On the other hand, when the continuity of the thyristor 7 during the operation is broken, the voltage appearing between output terminals (a) and (b) is converted to the emission of the light emitting diode 10a in a detection circuit 10 and a phototransistor 10b is conducted by the same. As a result, the base voltage of a transistor 10b rises and said voltage is acted on the negative side input terminal of a voltage comparator 11, whereby the charging circuit to the capacitor 5 is interrupted.
