Title: Manufacture of magnesium alloy casting
Inventor: YAMAMOTO YUKIO
IPC: C22C1/02
Filed: 1993-02-10
Abstract: PURPOSE:To effectively make the crystal grains in a magnesium alloy casting finely by adding the specific materials into the molten Mg alloy and casting. CONSTITUTION:The Mg alloy is charged into a crucible and heated and as crystal grain fining agent, 0.05-1.0wt.% CaVCN, 0.01-0.05wt.% Sr series metal are added. Then, CO2 gas is used as protecting gas. Therein, the lower limit of the adding quantity of CaVCN is to obtain the desired nucleating effect at the initial stage and this upper limit is regulated with the prevention from the generation of inclusion. On the other hand, the lower limit of Sr quantity is to obtain the restraining effect of the desired crystal growth and this upper limit is not to contribute to make the crystal grains finely. By this method, without bringing about the problems of fading of Sr and the generation of inclusion caused by CaVCN, the fining of the crystal grain in the casting can effectively be executed and strength of the magnesium alloy-made casting is improved.

Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To generate semantic further proper words used in a translation without any redundancy by preparing a new collocation extended to a collocation which is not registered in a dictionary for an inputted word string, and generating words used in a translation for the prepared new collocation. SOLUTION: The word/collocation in first language and the word/collocation in translation in second language corresponding to this are registered in a parallel translation dictionary table/rule table 6. A collocation group stored in a collocation storing buffer 7a is read, and a collocation having the maximum number of words including the same word is extracted as the partial collocation group of a new collocation by a partial collocation extracting part 5c. The extracted partial collocation group is stored in a partial collocation storing buffer 7b by a partial collocation storing part 5d. One of the same word (common word) of the two partial collocation is deleted, and the other partial collocation is connected so that one new collocation can be prepared by a new collocation preparing part 5e.  Moreover, words used in a translation in the second language whose meaning is judged to be proper to the prepared new collocation can be newly generated.

Title: Ultrasonic wave delay line
Inventor: UEMURA MICHIHIKO
IPC: H03H9/36
Filed: 1986-02-06
Abstract: PURPOSE:To reduce harmonic spurious noise by adopting the shape of a delay medium so that a wavefront of a sound wave propagated in the delay medium is inputted obliquely in an output transducer and a waveform component cancelling mutually the generation of an output voltage corresponding to the sound wave of the 3rd harmonic component is inputted. CONSTITUTION:The reflecting face 2a of the delay medium 2 is formed with a slope to an imaginary reflecting face 2a' so that the wavefront of the sound wave 3' reflected on the mirror surface of the reflecting face 2a is inputted obliquely to an output transducer 4. Assuming an angle between the reflecting face 2a and the imaginary reflecting face 2a' as theta, the sound wave 3' reflected in the reflecting face 2a is inputted to the output transducer 4 by an angle 2theta with respect to the imaginary reflecting wave 3''. Then the relation of alpha=2theta is established. Assuming the width of the output transducer 4 by W and the wavelength of the 3rd harmonic of the sound wave 3' as lambda, then the waveform component of opposite phase cancelling generation of an output voltage corresponding to the 3rd harmonic component is inputted to the transducer 4 in case the relation of lambda=Wsin 2theta exists. Thus, the main signal is not almost attenuated but only the spurious components of the 3rd harmonic or over are attenuated remarkably.

Title: Starting system for synchronous motor
Inventor: YAMAMOTO HIROO
IPC: H02P1/52
Filed: 1979-02-28
Abstract: PURPOSE:To permit a predetermined starting current to flow to armature windings in a synchronous motor when the motor is started by a power source of a variable frequency, by setting the motor and a power source transformer such that they are not operated in parallel in a starting period of operation of the motor, in which the motor is rotated at a low speed. CONSTITUTION:In order to start a synchronous motor 1, a switch 14 connected between the motor 1 and a power source transformer 12 is opened, and a breaker 8 for an output from a starter is closed. The motor 1 is thus started by a power source of a variable frequency. When an input voltage or frequency of the motor 1 has reached a predetermined level, the switch 14 is closed. When the starting of the motor 1 has been completed, a breaker 13 for the power source is closed, and the breaker 8 is opened. By applying this system, a decrease in the amount of an electric current flowing to the armature windings in the motor 1, that is, resulting from a large exciting current flowing, due to the saturation of an iron core, to the secondary winding of the power source transformer 12, can be prevented.
