Abstract: PROBLEM TO BE SOLVED: To obtain a speech translation terminal which does not lose an advantage that voice has and is easy to use by controlling a voice recognizing means, a speech synthesizing means and a language converting means from an external device when it is confirmed that the terminal is connected to the external device. SOLUTION: Voice that is inputted from a microphone 11 is sampled and inputted by an AD converting part 12. A voice recognizing part in a program in a single operation mode performs characteristic extraction of the inputted voice according to a CPU 1, calculates similarity by using standard patterns of all of sentences and words which you want to make recognized and outputs a sentence (word) of a standard pattern that has the highest similarity as a solution. Also, a translating part retrieves parallel translation of recognition results and an operation type, and when the operation type is a 'sentence', it transfers the recognition results and a parallel translation sentence to a liquid crystal display controlling part 8 and shows them on a liquid crystal display 7.  A voice synthesizing part synthesizes synthetic voice from the sent parallel translation sentence, a DA converting part 13 converts it into an analog signal and outputs it from a speaker 14. In this way, if you inputs, e.g. 'OHAYO (Good Morning)' by voice, it answers with 'Good Morning'.

Title: Variable conduction heat pipe strengthening
Inventor: KURUTO II KUNAIDERU
IPC: F28D15/06
Filed: 1991-05-09
Abstract: PURPOSE: To improve the flexibility of a heat pipe in design by attaching a limiting body to the inside of the heat pipe and properly holding the limiting body by an arbitrary fixed structure. CONSTITUTION: A limiting body 26 having a prescribed cross-sectional area is attached to the inside a heat pipe 10. The body 26 is connected to the end- section cap of the heat pipe 10 with such a steady line 28 as the steel pin having a small diameter. The body 26 can be made in the form of a steel plug or steel rod. Consequently, the flexibility of a gas-load type heat pipe in manufacture can be improved further. The flexibility makes the application of the same thermal load possible when a small-sized heat exchanger is used or that of a higher thermal load possible when the same size of heat exchanger is used. Therefore, the required length of a gas reservoir can be reduced. When, for example, a rod having a cross-sectional area which is the half of that of the heat pipe 10 is used as the limiting body 26, the length of the gas reservoir can be reduced to half.
