Title: Overvoltage protecting apparatus for inverter
Inventor: FUJITA HIROYOSHI
IPC: H02P3/18
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To synchronize the operating period of a cooling fan motor(FM) with that of an overvoltage protecting apparatus and to prolong the life of the FM by operating a switch for a power source to match a comparator output. SOLUTION: A switching element 45 obtains the output of a comparator 44, and detects the time of conducting regenerative power to a resistor 41 and the time of stopping the conduction. An operating circuit 47 generates a command DR1 via route changeover switch 471 at the time of conducting according to a command input DR1 by the output of the comparator 44, and the FM starts operating. When the conduction of the regenerative power to the resistor 41 is stopped by the comparator 44 and element 45, a command output DR2 is generated by the switch 471 and a delay arithmetic unit 472, and the operation of a switch 48 for a power source is delayed. Accordingly, the life of the FM for cooling the apparatus can be extended, thereby attempting to improve the reliability and to alleviate the maintenance of the FM replacement.

Title: Control system for multi-medium data
Inventor: KUSUNOKI SHIGEYUKI
IPC: G06F12/00
Filed: 1989-02-14
Abstract: PURPOSE:To easily secure the well-defined properties of names even in case the multi-medium data of the same name are registered via other users by controlling the names of the multi-medium data with use of a name having a hierarchical structure. CONSTITUTION:When a USER-B reads the multi-medium data, the name of the multi-medium data is designated as ALL/GROUP A/USER-B/DATA1. When the corresponding data name is inputted, a directory control system 2 reads the contents of a directory information control table 4 and retrieves a hierarchical structure. Thus the name of each multi-medium data is decided with use of a hierarchical naming rule in the case a large quantity of multi-medium data are stored and controlled by a computer. As a result, the data attribution and characteristics can be easily decided.

Title: Ultrasonic oscillator having monitor-control circuit
Inventor: KELLOGG SCOTT
IPC: A61B17/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To suppress an undesirable vibration, and improve performance by detecting an undesirable motion mode by a monitor-control circuit, and applying a control signal for an overriding to an oscillator in a manner to be recovered to a previously determined phase responding to the detection. SOLUTION: After ascertaining and storing a designated converter frequency range, an initial input voltage value for a voltage control oscillator 134 is ascertained using a monitor-control circuit 160. Thus, the oscillator 134 generates desirable frequencies. Then the control circuit 160 measures whether an acoustic assembly 50 operates under a resonant condition, and when the assembly 50 is operating under the unasonable condition, the control circuit 160 is decoupled, and a phase detector 132 and the voltage control oscillator 134 start outputting to the acoustic assembly 50. Then, when the control circuit 160 detects a non- keeping of the resonant condition, the control circuit 160 searches the stored resonant frequency, and establishes a new input to the voltage control oscillator 134, and the resonant condition is re-established.  Thus, an undesirable vibration is suppressed, and performance can be improved.

Title: High saturation magnetization iron-nitrogen-based thin film and its formation method
Inventor: MATSUOKA SHIGETO
IPC: H01F10/14
Filed: 1990-02-16
Abstract: PURPOSE:To easily obtain a thin film whose reproducibility is good and whose saturation magnetization is high by a method wherein a gas flow value used to obtain a large saturation magnetization is set to a specific range. CONSTITUTION:The composition of a high saturation magnetization iron nitrogen-based thin film is expressed in Formula I. When (X) is smaller than 0.03, it is not effective, and a film which is nearly equal to that of pure iron is obtained; when it is larger than 0.15, a low saturation magnetization face corresponding to Fe4N appears and a saturation magnetization is reduced. When (y) is larger than 0.1, a different phase appears and the saturation magnetization is reduced. When (z) is larger than 0.1, the saturation magnetization is reduced by the effect of oxidation in the same manner. When the value of y+z is larger than 0.1, the saturation magnetization which is larger than that of iron cannot be obtained. Even when the value of x+y+z is 0.05 or lower, the saturation magnetization of iron cannot be obtained; when it is larger than 0.25, the saturation magnetization is lowered in the same manner. Thereby, it is possible to obtain the thin film whose reproducibility is good and whose saturation magnetization is high.
