Title: Voice analyzing and synthesizing device
Inventor: TOUKADO TETSUO
IPC: G10L25/78
Filed: 1990-07-20
Abstract: PURPOSE:To obtain a proper sound source even if voice/no-voice information can not be corrected by enabling a synthesis part to calculate voice/no-voice information from voice spectrum information by using the same algorithm with an analysis part, compare it with received information, and correct the information. CONSTITUTION:The voice spectrum information C(14) is sent from a separator 3 to a voice/no-voice decision device 9 to calculate reduced power PL. The power PL is compared with a voice/no-voice threshold value PLTH to calculate the voice/no-voice IXP. Then the information IXP from the decision device 9, the information IVN from the separator 3, and pitch information IPN are sent to a corrector 10, which substitutes held last-frame voice/no-voice information IVB with the information INV as correcting operation only when IPN not equal to 0 and 'IVN not equal to  IXP'. Then a sound source switch 6 is switched to a noise generator 5 when INV = 0 or to a pulse generator 4 when INV not equal to  0 to obtain the proper sound source for a synthesizing filter device 7.

Also, slits 1a are formed through both the surface and rear of the elastic body 1 between the elastic body 1 and a doughnut-like support 1c on the periphery of the elastic body 1 inside it.  Further, the piezoelectric body 2 is stuck to only the circular setting surface 1d, and the setting surface 1d and the doughnut-like support 1c are connected through belt-like beams 1b each having a joining part for joining the beam 1b to the support 1c and another joining part for joining the beam 1b to the setting surface 1d, wherein each of these joining parts is formed so that its thickness is smaller than its width in the radial direction of the setting surface 1d, to amplify excitation of the piezoelectric body 2. Thus, the elastic body 1 is elastically vibrated in the thickness direction of the piezoelectric body 2 by excitation of the piezoelectric body 2.

Abstract: PURPOSE:To obtain a device of high quality with high yield by a method wherein a connection hole for a semiconductor element or a part thereof is formed of a metallic or an alloy layer which constitutes a wiring layer, and the wiring region except the hole part is composed of only a kind thereof. CONSTITUTION:A P-base 105, an N<+> emitter 106, and an N<+> collector lead-out layer 107 are formed by selectively providing apertures through an SiO2 film 102 on an N type Si substrate 101. Next, a hole is bored 108 through the SiO2 102, Pt is vapor-deposited, being heat-treated, and a PtSi 109 is formed on apertures 106-108, then removing the Pt with aqua regia. Next, Ti/W metallic layers 110-112 are provided, and the elements are connected each other by applying an Al wiring. At this time, since there is no Ti/W under the mutual connection Al wiring, reverse trapezoidal cross-section is not caused at the time of Al etching, the problem of wiring lifetime and others in quality can be eliminated, therefore a device with a metal-semiconductor junction diode being built-in is obtained with high yield.

Title: Electronic parts
Inventor: HOASHI YOSHIAKI
IPC: G01S7/48
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defective connection between chip parts and a circuit board in a package due to an environmental change in use, in electronic parts directly mounted on the circuit board. SOLUTION: A photodiode 1 is composed of chip parts 10 and a ceramic package 20 housing the parts 10. On the external surface of the package 20, a pair of anode electrode 20a and cathode electrode 20k respectively connected to the anode and cathode of the parts 10, and a plurality of electrodes 20x for fixation, are formed. The electrodes are arranged from each side face of the package 20 in the length wise direction to the rear surface of the package 20 at regular intervals symmetrically to each other with respect to the center of the package 20.  Therefore, when the photodiode 1 is soldered to a circuit board 5 through the electrodes, the occurrence of defective connection between a specific electrode section and the circuit board 5 can be prevented by dispersing the stresses applied to soldered sections HD caused by a temperature change which occurs at the soldering time due to the difference between the coefficients of thermal expansion between the package 20 and the board 5 through each electrode.

Title: Liquid surface sensor
Inventor: HIRATE MASATOSHI
IPC: G01F23/28
Filed: 1988-08-04
Abstract: PURPOSE:To achieve a higher detection accuracy by arranging a prism with a cross-sec tion thereof triangular, on the bottom of which a light emitting element and a photo detector are disposed in juxtaposition so that a reflecting surface thereof is turned in a vertical way to make a liquid adhering to the surface thereof flow down quickly when the prism is exposed from a liquid surface. CONSTITUTION:Two prisms 4 and 5 are formed integral at upper and lower positions of a holder 1 in such a manner that reflecting surfaces (a) and (b) on both sides of a triangle with a top angle of 90 deg. are parallel with each other in a vertical way and photoreflectors (e) and (f) having a light emitting element (c) and a photo detector (d) arranged in parallel are provided at positions corresponding to the prisms 4 and 5. When the prism 4(5) is in a liquid, light from the light emitting element (c) is refracted outside the prism 4 at the reflecting surface (a) and fails to be received with the photo detector (d). The moment the reflecting surfaces (a) and (b) of the prism 4 touch air as a liquid surface lowers, light from the light emitting element (c) enters the photo detector (d) through the reflecting surfaces (a) and (b). At this point, as the liquid on the surface of the reflecting surface flows down quickly, a light reception signal is detected quickly thereby achieving a higher detection accuracy.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of a creak of a brake and judder by footing a thickness reduction part, whose cross section is cut down, between a mounting face connected to a rotary shaft in a wheel and a cylinder part with which a brake shoe is brought into slide contact. SOLUTION: A brake drum 10 formed into a bottomed cylinder is provided with a cylinder part 20 and a disc part 30. A sliding contact face 21 for a brake shoe is formed in the inner circumference of the cylinder part 20 while the disc part 30 is provided with a mounting face 31 to the rotary shaft, and a stepped part 33 is formed in the disc part 30 while a thickness reduction part 34, whose cross section is cut down, is formed between the mounting face 31 and the cylinder part 20. The stepped part 33 increases rigidity of the mounting face 31, and coupling of vibration modes for the disc part 30 and for the cylinder part 20 is suppressed, so that a creak of a brake can be prevented. Even if distortion is generated in the mounting face 31 because of an input from the rotary shaft side, the disc part 30 is deformed in the vicinity of the thickness reduction part 34 provided with relatively low rigidity, and deformation of the cylinder part 20 is suppressed and circularity of the cylinder part 20 is maintained, so that generation of judder and the like can be prevented.
