Abstract: PURPOSE:To increase the quantity of drain discharge and enhance drainage performance by installing a drain discharge cylinder in the radial outward direction of a drain outer cylinder, and in the direction deviated leftward along the counterclockwise flow of whirlpools produced in a drain trap. CONSTITUTION:A sealing cylinder 21 is enveloped with a drain outer cylinder 22 while a drain cylinder 24 is inserted into the sealing cylinder 21, thereby constituting a drain trap. In this drain trap, a drain discharge cylinder 23 is installed in the radial outward direction of the drain outer cylinder 22, and deviated leftward along the direction of a counterclockwise flow of whirlpools produced in the drain trap. Furthermore, it is more preferable that a plurality of lines 28 be installed in the drain cylinder 24, which extend radially, and in the shape of whirlpools. Furthermore, it is more preferable that a plurality of long holes 37a, which extend radially, and in the shape of whirlpools, is formed on a drain pan 37 which covers the upper end opening of the drain cylinder 24. This construction makes it possible to turn the flow of drain in the drain cylinder 24 to a turbulent flow directed at the drain discharge cylinder 23 and smooth the flow in a drain chamber 3000 and hence increases the quantity of drain discharge.

Title: Ceramic circuit board and manufacture thereof
Inventor: NAKADA YOSHIKAZU
IPC: H05K1/09
Filed: 1995-04-21
Abstract: PURPOSE: To reduce short-circuiting via and electrode pad on a thick film pattern upper surface and the solder bump of a signal line by using the thick film pattern containing molybdenum as a main ingredient as a solder dam. CONSTITUTION: Conductor paste containing molybdenum as a main ingredient is filled in a thick film pattern forming part to form a thick film pattern 18. Only the pattern 18 is covered with nickel, gold as a plated film 21 by an electroless plating process to form an electrode pad 32. A ceramic circuit board 10 on which the solder dam 18a and a signal line 31 are formed of the molybdenum is formed. Since the pattern 18 lacks solder wettability, the thick film pattern of the periphery of the plate film becomes a solder dam 18a. The line 31 near the periphery of the pad also lacks solder wettability, and hence the pad 32 is not short-circuited to the line 31 via the bump 22. Since the bump 22 is not extended at the wet part to the thick film pattern of the periphery of the pad, the height of the bump 22 becomes uniform and the chip 23 can be mounted without inclining.

Abstract: PURPOSE:To reduce the capacity of a cycloconverter as an exciter by obtaining the accumulated of the instantaneous values of exciting currents or voltage at every phase of a rotor winding and controlling the phase angle of the exciting voltage of the rotor winding on the basis of the accumulated. CONSTITUTION:Secondary currents are acquired by secondary-circuit current detectors 24a, 24b, 24c, the values of the secondary currents are input to an accumulating section 25, and the accumulated value is obtained at every phase. A maximum-value computing section 26 acquires the maximum value of the accumulated value obtained by the accumulating section 25. The maximum value is input to a comparison section 27, and an output from the comparison section 27 is multiplied by a constant and the quantity of correction of a phase-angle controlled variable is acquired by a multiplying section 28. A correction value obtained and an output from a phase angle computing section 16 are added by an adding section 29. The phase-angle of the exciting voltage of a rotor winding is controlled on the basis of the accumulation of the instantaneous values of said each phase, and the title system is operated within the range of the preset number of revolution, thus resulting in passage through a section close to slip 1 zero in a short time, then reducing the capacity of a cycloconverter as an exciter.

Title: Voice signal processor
Inventor: SHUDO KATSUYUKI
IPC: G10L21/04
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the quality of voices so as to facilitate listening even if voice signals are pitch-converted by providing a non-read information quantity detecting means for detecting a non-read information quantity or the like in a memory. SOLUTION: Voice signals reproduced at a high speed are inputted via a LPF1 to a ADC by an input terminal IN, A/D converted at a high speed and written in a memory MRY. In this case, among the voice signals written in the MRY, a non-read signal quantity (non-read information) is detected by a write end counter WDCNT. Thus, when a specified upper limit is reached, renewal of a write address WAD is stopped so as to prohibit writing in the MRY, and when a lower limit is reached, writing in the MRY is performed by resuming the renewal of the WAD. Thus, since an erroneous operation is prevented and a reproducing time is lengthened without any interruptions, the quality of voices is improved to facilitate listening even if voice signals are pitch-converted.

Title: Piezoelectric transformer type power converter
Inventor: ABE TORU
IPC: H01L41/107
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent efficiency from lowering when temperature rises, and to enable maintenance of high-efficiency operation by causing an inductance element to have a negative temperature coefficient in its inductance characteristic. SOLUTION: Since the temperature characteristic of the inductance value of a compensating inductor 30 has a negative temperature coefficient, and the inductance value of the compensating inductor 30 decreases, even if the ambient temperature rises and the input electrostatic capacity CPI of a piezoelectric transformer 50 increases, excitation voltage VDS remains in the shape of a half-wave sinusoidal wave. Accordingly, zero-voltage switching operation in which VDS is zero when a MOSFET 20 turns on is kept, and increase of the loss of the MOSFET 20 is prevented. In this way, efficiency lowering of a piezoelectric transformer type power converter caused by the increase of the input electrostatic capacity of a piezoelectric transformer owing to temperature increase can be prevented without increasing parts at all.  Besides, generation of electromagnetic noise is also suppressed, since the zero-voltage switching state of a main switch can be maintained.

Abstract: PURPOSE:To enhace a character input speed and improve the operability, by reporting information of the number of character strings in the second classification corresponding to one character string in the first classification with an acoustic means in case of character conversion. CONSTITUTION:Kana (Japanese syllabary) characters to be converted to Kanji (Chinese character) are inputted to a controlling part 2 by the key operation on a keyboard part 1. When the indication of the conversion start to Kanji is given to the controlling part 2 by the operation of a conversion start key, the controlling part 2 scans the index to read out Kanji, which have the same pronunciation as inputted Kana characters, from the Kanji section of a dictionary memory 3. Readout Kanji are transmitted and displayed on a connection line display part 4 and is stored in a buffer memory 5. When the controlling part reads out Kanji, it reads out information of the number of homonyms from the homonym number section and transmits this information to an acoustic converting part 6. The acoustic converting part 6 converts information of the number of homonyms to sounds to report the number of homonyms to the operator through hearing.
