Title: Sound control device of radio telephone set
Inventor: TOKI YUJI
IPC: H04B7/26
Filed: 1991-10-01
Abstract: PURPOSE:To make it possible to perform a clear call even at a place where environmental noise is loud by installing a noise level detection microphone at a different position from a transmission microphone and performing a transmission of the difference of a transmission microphone and a noise level detection microphone. CONSTITUTION:At the back side of a transmission microphone 3, a noise level detection microphone 4 is installed. The voice signals from microphones 3, 4 enters a difference device 12 via preamplifiers 10, 11 and the difference output is obtained. Thus, by taking the difference, the common noise entering the microphones 3, 4 is cancelled. This difference output is outputted to a variable gain amplifier 15. By a noise signal obtained by a noise signal detectors 13 and a control signal amplifier 14, the output is controlled so that it may be made smaller when the noise signal is large and it may be made larger when the noise signal is small. The transmission voice output which is obtained at this place and is not affected by noise is transmitted to a modulation circuit for radio equipment.

Title: Electromagnetic flowmeter
Inventor: KOMATSU SHINGO
IPC: G01F1/58
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive electromagnetic flowmeter having an excellent corrosion resistance and a small size by providing measuring tubes, magnetic field generating means, electrodes, magnetic path forming members, and a case. SOLUTION: Since closed magnetic paths of the magnetic fields of coils 2a and 2b are formed by means of first and second magnetic path forming members 5a, 5b and 6a, 6b, a case 4 can be formed out of a nonmagnetic material. As a result, the magnetic fields of the coils 2a and 2b are not disturbed and the electromagnetic flowmeter can always stably measure the flow rate of a fluid. When the members 5a and 5b are respectively provided at both end sections of a measuring tube 1a, the magnetic flux generated between the inner cores 9a and 9b of the coils 2a and 2b is not influenced adversely, because a magnetic flux feeding-back circuit is formed at a position far from the magnetic flux. In addition, measuring tubes 1a and 1b can be made of the same material as that of the case 4 and can be welded stably to the case 4.  Therefore, the highly durable electromagnetic flowmeter which does not require any anticorrosion painting can be obtained at a low cost.

Title: Manufacture of semiconductor device
Inventor: NISHIOKA TAIJO
IPC: H01L21/316
Filed: 1985-12-16
Abstract: PURPOSE:To reduce fixed charges and an interface level in a Ta2O5 film, and to form a capacitor having a small area and large capacitance required for an LSI by heating the interface of Ta2O5/Si in the mixed atmosphere, which contains no oxygen, of hydrogen and steam or the mixed atmosphere of an inert gas and steam. CONSTITUTION:A capacitor in which Ta2O5 is formed onto an Si substrate 1 through a reactive sputtering method is heated in the mixed gas of hydrogen and steam. Consequently, fixed charges and an interface level are reduced, thus acquiring the capacitor having stable electrical properties. The same effect is obtained even when an inert gas, such as nitrogen or argon gas containing steam is used in place of the mixed gas of hydrogen and steam as the gas. Even when a high melting-point metal, such as W, Mo, TiW, a W silicon alloy, a Mo silicon alloy, etc. is exposed from a wafer surface, annealing by the mixed gas of hydrogen and steam does not oxidize these metals, and does not oxidize there high melting-point metals, feeding oxygen to a high permittivity insulating film. Accordingly, a dielectric having little fixed charges and a small interface level can be shaped in an insulating film consisting of Ta2O5, etc. having a large relative inductivity.

Title: Roll paper printer
Inventor: NAKAYAMA HIROYUKI
IPC: B41J15/04
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a roll paper printer which can correctly detect an open, close state of an opening lid of a roll paper load part. SOLUTION: When an opening lid 30 of a roll paper-loading part of a roll paper-loading mechanism of an ink-jet printer is closed and a hook 28h of a lock lever 280 is locked, the fact that the opening lid is closed is detected by a photointerrupter 288. Since an open, close state of the opening lid 30 is detected on the basis of a position of the lock lever 280, it is detected more correctly in comparison with the case where it is detected on the basis of a position of the opening lid itself. The lock lever 280 can turn to a lock position and an unlock position. Even in an event that the opening lid 30 cannot be opened, turning the lock lever 280 to the unlock position makes the photointerrupter 288 detect that the opening lid is opened. An abnormal recovery operation such as driving a roll paper feed motor rearward or the like can be conveniently started irrespective of an actual open, close state of the opening lid.
