Title: Superconductive magnet apparatus
Inventor: ONOE TATSUYA
IPC: H01F6/04
Filed: 1989-06-29
Abstract: PURPOSE:To keep a superconductive coil at a cryogenic state stably even if the liquid level of a cryogenic refrigerant is lowered in a storage tank by extending a heat conducting part comprising a good heat conductor toward the bottom part of the storage tank from a soaking layer. CONSTITUTION:When the surface of liquid helium 5 in a liquid helium tank 1 is at a level 8, a cryogenic state is kept for superconductive coils 2 and 3. When the liquid level lowered to a level 9, a coil 2 and a second soaking layer 7 are exposed on the liquid surface. Since a second heat conducting part 12 which is made to extend from the layer 7 is immersed in the helium 5, the entire layer is kept at the cryogenic state. When the liquid surface is further lowered to a level 10, a first heat conducting part 11 which extends to the lower part 1 acts as the same way as the conducting part 12. Thus, an entire first soaking layer 6 is kept at the cryogenic state. In this way, the superconductive coils can be kept at the cryogenic state stably by extending the superconducting parts from the soaking layers.

Title: Motor controller and control method therefor
Inventor: YAMADA EIJI
IPC: H02P6/18
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent the detecting accuracy from being lowered, even if there is change of requested torque in a case such that an electrical angle is detected without the use of a sensor. SOLUTION: A motor controller for controlling the operation of a synchronous motor for rotating a rotor by applying a multi-phase AC current to a coil is constituted as explained below. An electrical angle detecting means 220 is prepared to detect an electrical angle of rotor without the use of a sensor based on a current, which flows depending on a detection voltage applied to a coil. Moreover, a torque control means 200 is prepared to apply a voltage to output a torque to the coil depending on the requested torque. A control means 228 adjusts the execution timing of both means, so that change in current by the torque control means 200 does not give adverse effects on the process of the electrical angle detecting means 220.  Here, the execution timing of both means may be scheduled in advance, and the execution of electrical angle detecting process may be a waited depending on change of the requested torque. As a result, even if the torque changes, electrical angle can be detected with high accuracy.

Title: Device and method for controlling relay
Inventor: RUISU ESU PORUSUTAA
IPC: H01H47/32
Filed: 1989-06-28
Abstract: PURPOSE: To reduce the generation of arc in a relay contact so as to prolong the lifetime of a relay by controlling an energizing point so that a relay contact is switched during the time when the current flowing through the relay contact is near zero. CONSTITUTION: Time of the generation of arc is measured, and a relay 42 is operated so that a contact of the relay 42 is switched when the current flowing an AC load circuit is zero. Namely, a logical device measures the arc duration, and stores the duration information in a memory related to the relay 42. Thereafter, each time when the relay opening command is output, this logical device references the memory related to the relay 42, and adds the stored time to the time of voltage tolerance at zero, which is showed by a line 90, and thereafter, the logical device drives the relay on the basis of the driving signal on a line 44. Since a contact 14 of the relay 42 is opened at a part 27, in which voltage intolerance is zero, arc is not generated at the time of opening a circuit, and the lifetime of the relay is prolonged.

Title: Preparation of organic bromide
Inventor: HARADA TAKAO
IPC: C07B31/00
Filed: 1979-12-21
Abstract: PURPOSE: To obtain an organic bromide useful as an intermediate of pharmaceuticals and pesticides, in high purity and yield, stably, by brominating an unsaturated organic compound in the presence of a hydrogen halide solution under mild conditions.  
     CONSTITUTION: An organic bromine compound is prepared by brominating an unsaturated organic compound (e.g. methyl 3-pentenoate, n-butyl methacrylate, etc.) in the presence of a solution of a hydrogen halide (e.g. hydrobromic acid). The reaction temperature is ≤150°C, and lower the better. When the bromination is carried out with bromine dissolved in the hydrogen halide solution, the side reactions can be suppressed because the bromine forms a complex having lower activity and acts as a homogeneous system. The hydrogen halide solution can be recovered and reused.

Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To improve a shock absorbing capability at the time of a collision, particularly a side impact, for the same shock absorbing energy and the same weight by arranging an annular wire as a reinforcing member. SOLUTION: A wire 1 is annularly arranged to be wound around two fixing tools 2 (A). The load applied to the wire 1 is self-compensatingly converted, thus a tensile load can be applied to the wire 1 if the initial warp is minimized. When the wire 1 is arranged annularly, the load concentration to a fixed section is avoided, and the danger of the breakage of the fixed section is avoided. An annular steel wire (A) and a member (B) arranged with the annular wire 1 are shown in this example. The steel wire has the diameter of about 5 mm and the strength of about 1500 MPa. The member has the thickness of 1.2 mm, the square cross section with a side of 70 mm and the length of 800 mm. Lightness and a high shock absorbing capability can be concurrently obtained.
