Title: Envelope waveform generating device
Inventor: KOZUKI KOICHI
IPC: G10H1/057
Filed: 1990-07-10
Abstract: PURPOSE:To generate an envelope waveform with an attach feeling even when key-off timing is fast by setting a specific position on the envelope waveform, and comparing a position on the envelope waveform at key-off timing with the specific position and delaying a key-off process. CONSTITUTION:The device consists of a central processing unit(CPU) 10, a key detecting circuit 13, an EG setting switch 14, a sound source circuit 16, a keyboard 18, etc. Then the specific position DP is set on the envelope waveform and the position on the envelope at the key-off timing is compared with the specific position DP to delay the key-off processing of the envelope waveform according to the comparison result. Consequently, even when the key-off timing is too fast, the envelope waveform having the sufficient attach feeling is generated.

Filed: 1994-07-08
Abstract: PURPOSE:To prevent the introduction of a diffraction light unnecessary for a light receiving element and to improve a detecting accuracy by suitably disposing axial directions of a polarization beam splitter and a 174 wavelength plate. CONSTITUTION:When an mth-order diffraction light obtained by introducing a luminous flux reflected by a polarization beam splitter 9 as a clockwise circularly polarized light via a 1/4 wavelength plate 5) to a diffraction grating 3, reflecting it by a condensing system 20 and returning it is again passed through the plate 51, it becomes a linearly polarized light vibrated in a direction perpendicular to a forward path, passes the splitter 9, and is guided to a photoreceiver. On the other hand, a luminous flux obtained by initially reflecting by the splitter 9, passing it through the plate 51 as a clockwise circularly polarized light and regularly reflecting it by the grating 3 is passed through a wavelength plate 52 and incident perpendicularly to the plate 51, and hence passed through the splitter 9 and not incident on the photoreceiver. The flux which is passed through the splitter 9 and regularly reflected on the grating 3 is similarly not incident to the photoreceiver.

Title: Lighting optical device
Inventor: MIZUTANI HIDEO
IPC: G02B21/36
Filed: 1984-08-30
Abstract: PURPOSE:To increase the quantity of light supplied from a strobe device to a subject by providing a translucent surface in a shape nearly equal to that of the wave front of luminous flux from the strobe device between the light source lamp and strobe device of the lighting optical device. CONSTITUTION:When the strobe 3 is turned on for photography, luminous flux which is emitted by the strobe 3 in nearly the same direction and incident on a collector lens 4 is guided to a body to be lighted and luminous flux which is emitted by the strobe 3 and incident on a relay lens 2 is reflected by a parallel plane plate 5a at a specific reflection factor. The luminous flux from the strobe which is reflected by the translucent surface 5a travels back through its optical path to the strobe 3 and is converted on the collector lens 4 to enters the collector lens 4 and reach the object body. Thus, a sufficient quantity of light is supplied for photography and the luminous flux from an observation optical source is attenuated by the translucent surface, so the constitution is simplified.

Filed: 1986-07-31
Abstract: PURPOSE:To make the min. detectable pulse width narrow without deteriorating resolving power and to enhance the utilization factor of an elastic surface wave, by providing a beam polarizing means for generating an elastic surface wave to the central part of parallel laser beams. CONSTITUTION:The beam from a beam source 3 is converted to parallel beams through a wave guide 2 and a flat lens 4. Next, said parallel beams are polaralized by elastic surface waves 8, 9 emitted in both directions corresponding to the frequency of the electric signal inputted from the elastic surface wave electrode 5 provided to the central part of said parallel beams and condensed by a flat lens 6 to reach a beam detector array 7. In this case, the parallel beam simultaneously receives beam polarization by the elastic surface waves in two directions excited by the same electric signal and, therefore, almost 100% of elastic surface wave energy can be utilized and the utilization factor of the elastic surface waves is enhanced. The polarized beam at this time is polarized by upper and lower separate elastic surface waves of parallel laser beam to reach the array 7 through the lens 6 and frequency can be read as the positional change of condensed beam.

Title: Optical coupling element
Inventor: FUKUNAGA MASANORI
IPC: H01L31/12
Filed: 1985-08-19
Abstract: PURPOSE:To enable the input signals from a plurality of light emitting elements to be transmitted with a single photo detector by causing the polarization orientations of two light emitting elements to orthogonally cross each other, and arranging polarizers above the photo detecting surfaces of the photo detecting portions so as to orthogonally cross each other. CONSTITUTION:By causing the polarization orientations of linear polarizers 5a, 5b to orthogonally cross each other, the output lights of the respective light emitting diodes 3a, 3b become single linear polarized lights orthogonally crossing each other. A photo detector 4 is arranged so that the polarization orientations of linear polarizers 6a, 6b are caused to orthogonally cross each other respectively on the photo detecting surfaces of photo diodes 4a, 4b in a monolithic photo IC chip, by which the polarization orientations of the respective linear polarizers 5a and 6a and linear polarizers 5b and 6b are coincident. And the linear polarizers 5a, 5b and 6a, 6b transmit only the light of the polarization component coincident with their polarization orientations. Therefore, since the two photo diodes 4a, 4b provided in the photo detector 4 have sensibility only in one of the light emitting elements 3a, 3b, the input signals from the two light emitting elements can be transmitted with a single photo detector 4.
