Filed: 1985-04-30
Abstract: PURPOSE:To simplify an optical system and a lens barrel by arranging an optical elastic body on the optical axis of a dichroic mirror on the object side and varying the refracting power of the optical elastic body in focus detection. CONSTITUTION:The optical elastic body 2 is, for example, a parallel plane body during photographing so that the photography is not affected much, and has one surface deformed so as to has positive refracting power during focus detection.

Abstract: PURPOSE:To apply a prism for correcting the line of sight not only to a stereoscopic photograph whose specification such as size is fixed but also to the stereoscopic picture of a moving picture projected on a screen or a television by arranging the prism for correcting the line of sight in front of eyes. CONSTITUTION:The line of sight in the case of seeing an ordinary picture is like the line of sight of the left eye 5 and the line of sight of the right eye 6 when a viewing point exists in the left side picture 1. However, in the case of stereoscopic vision, the line of sight of the right eye 6 is changed to a line of sight of the right eye 8 by fixing the prism 9 in front of the right eye 4 so that its ridge 10 may be inside. Namely, the line of sight in the case of seeing the ordinary picture is corrected to the line of sight of the stereoscopic vision with the naked eye by arranging the prism 9 in front of the eye. Thus, by making an optical system so simple that the line of sight has only to be changed by using the prism 9 as it is, distance to the picture is not restricted and the stereoscopic effect of the sterescopic picture of the animation picture projected on the screen and the television is experienced.

Title: Voice recognizing device
Inventor: ARIYOSHI TAKASHI
IPC: G10L21/02
Filed: 1989-04-13
Abstract: PURPOSE:To correctly eliminate noise spectra from voice spectra including a noise by obtaining the ratio of the gain of an AGC at the time of holding the presumed value of the noise spectra to the gain of the AGC in a voice section, and regulating the presumed value of the noise spectral based on the ratio. CONSTITUTION:When the voice is not detected by a voice section detecting part 5, a noise presuming part 6 sets the output spectral mean value of an A/D converter having approximate 20 frames at the noise spectra, and holds the noise spectrum presumed value until the value is updated again. A gain ratio calculating part 7 calculates the ratio of the output spectrum value of an A/D converter to the held noise spectral value, and the minimum ratio value is set at the ratio of the gain of the AGC at the time of presuming the noise spectrum presumed value to the gain of the AGC in the voice section. A spectrum subtracting part 8 subtracts the value, which is obtained by multiplying the noise spectrum presumed value by the gain ratio calculated by a gain ratio calculating part, from the output spectrum value of the A/D converter, and the obtained value is set at the voice spectra from which the noise is eliminated.

Abstract: PURPOSE:To aim at enhancing the efficiency of a fan, by arranging a control member for controlling forced vortexes in the vicinity of the outer peripheral surface of an impeller so as to make the member possible to move to an arbitrary position in the circumferential direction of the impeller and as well possible to be fixed. CONSTITUTION:A control member 6 having both ends in a rod-like shape, for controlling forced voltexes produced in the cross-flow fan is positioned in the vivinity of the outer peripheral surface of an impeller where no affection is direcly made by pierecing stream.

Title: Semiconductor device and fabrication thereof
Inventor: NISHIHARA SHUSUKE
IPC: H01L29/78
Filed: 1993-04-21
Abstract: PURPOSE:To provide an IGBT in which the short circuit resistance can be enhanced without lowering the saturation voltage. CONSTITUTION:A p+ diffusion layer 22, an n+ emitter region 23, and a Ti layer 53 corresponding to a polysilicon gate electrode 41 are formed under an interlayer insulation film 32. The Ti layer 53 corresponding to the p+ diffusion layer 22 and the emitter region 23 constitutes an auxiliary emitter electrode layer comprising a pure Ti layer 53a and a titanium silicide layer 53b. The titanium silicide layer 53b provides a good ohmic contact between the p+ diffusion layer 22, the emitter region 23 and an emitter electrode 51. Ti has high melting point and low and uniform resistance. Saturation voltage is lowered because of 100% emitter bypass rate and short circuit resistance is enhanced because the current flows uniformly even during short circuit of load to eliminate weak point. The Ti layer 53 corresponding to the gate electrode 41 comprises the pure Ti layer 53a not yet reacted and the titanium polycide layer 53c, and serves to lower the resistance of the gate electrode 41.

Title: Semiconductor input protective device
Inventor: MISU KAZUHITO
IPC: H01L27/02
Filed: 1987-04-17
Abstract: PURPOSE:To enable a layout freely by forming first and second impurity diffusion layers having a conductivity type reverse to a substrate and lowering an effect on an internal circuit of surge voltage applied to an input terminal. CONSTITUTION:When surge voltage is applied to an input bonding pad 5a, a punch-through is generated because impurity diffusion layers 1a, 1b are shaped at an extremely narrow space, and the diffusion layers 1a and 1b are brought to the state of a short circuit. Since an impurity diffusion layer resistor 1c is isolated from the diffusion layers 1a, 1b by a field oxide film 12 and arranged at that time, N-P-N bipolar conduction is not generated between the resistor 1c and the diffusion layer 1a or 1b. Since the response time of a punch-through from the diffusion layer 1a to 1b is shorter than the time constant of the resistor 1c, currents by surge voltage are punched through from the diffusion layer 1a to 1b first, voltage applied to the resistor 1c is elevated up to punch-through voltage, and peak voltage is lowered. Accordingly, the degree of freedom of a layout is improved, and a protective function can also be enhanced.
