Title: Polarizing prism and reflection type optical modulating projector
Inventor: TSUKADA MASASHI
IPC: G02B5/04
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To provide the polarizing prism which makes the reflection type optical modulating projector small-sized by shortening the optical path length of its optical system and the reflection type optical modulating projector which uses the polarizing prism. SOLUTION: This prism is formed sandwiching and sticking a thin plate glass 1b between two triangular prisms 1a and 1c made of optical glass. Optical thin films are formed on 1ab and 1bc between the triangular prisms 1a and 1c and thin plate glass 1b and the 1ab between the triangular prism 1a and thin plate glass 1b is given spectral characteristics for transmitted P-polarized light and transmitted and reflected light of S-polarized light. Further, the 1bc between the triangular prism 1c and thin plate glass 1b is given spectral characteristics for transmitted S-polarized light and transmitted and reflected light of P-polarized light.  Thus, the polarizing prism having a polarized beam splitter function with the mutually independent spectral characteristics of transmitted light and reflected light for the P-polarized light and S-polarized light is obtained, and consequently the reflection type optical modulating projector is constituted.

Title: Driving circuit of charge transfer image pickup element
Inventor: KOUNO AKIHIRO
IPC: H04N5/335
Filed: 1982-01-22
Abstract: PURPOSE:To obtain a driving circuit which has a small number of component parts with a low level of power consumption, by providing two switching circuits and a capcacitor. CONSTITUTION:A capacitor 64 is charged with the voltage supplied to a switching circuit 51 since a transistor (TR) 66 of a switching circuit 61 is turned on in a vertical transfer period. Then a TR65 of the circuit 61 is turned on in a vertical blanking period, the potential at the other end 52 of a capacitor 64 rises up over the vertical transfer pulse amplitude by an amount equivalent to the voltage supplied to the circuit 61. That is, the reading pulse rises up. Then the pulse amplitude necessary to read out a photoelectric converting part is added to the vertical transfer pulse amplitude for the potential at an output terminal 57. Here the circuit 51 generating a double phase vertical transfer pulse supplies the vertical transfer timing pulse so that the TR55 is set at a high level or turned on alternately in a vertical blanking period. As a result, an interlace operation is realized. Thus the number of component parts is decreased with a low level of power consumption.

Filed: 1990-01-19
Abstract: PURPOSE:To prevent a virtual sound source position from being moved even when a listener moves by receiving an acoustic signal transmitted from a transmitting means, finding a transfer characteristic, processing it and supplying to a headphone unit. CONSTITUTION:A sound source device 20 receives reference signals S1 and S2 for detecting a head part position transmitted from transmitting parts 18L and 18R of a headphone device 10 side by a receiving part 21. Based on a receiving output by the receiving part 21, a transfer characteristic is operated by an acoustic signal processing circuit 26 and signal processing which is made to correspond to the change of the transfer characteristic with the movement of a listener and the rotation of the head part in real time is performed to acoustic signals SL and SR of left and right channels. Then, the acoustic signals SL' and SR' of the left and right channels processed by the circuit 26 are transmitted to a receiving part 11. The receiving part 11 supplies received signals to headphone units 15R and 15L of the left and right channels. Thus, natural sound image localization feeling of which a virtual sound source does not move can be obtained.

Title: Loudspeaker
Inventor: YAMAGISHI KIYOSHI
IPC: H04R7/12
Filed: 1990-01-18
Abstract: PURPOSE:To enlarge directivity at a hearing point and to improve sound quality by constituting a loudspeaker by using sub cones for which right and left radius is made equal to the center line of the loudspeaker and the curvatures of right and left cone curves are asymmetric. CONSTITUTION:The sub cone 8 is circular, namely, the right and left radius is equal. However, on an X-0-Y sectional plane passing through the center line of the loudspeaker, the curvature R2 of the cone curve on the right side of the center line is made larger than a curvature R1 of the left side. A hearing point Q mainly receives direct sounds caused by radiation waves form the facing left side sub cone surface. However, since the curvature of the sub cone on the hearing point Q side, namely, on the right side is made larger, the radiation waves form the left side sub cone are not interrupted. Then, the effective area of the left side sub cone facing to the hearing point of the sub cone is increased and the direct sounds are increased as well. Therefore, the flatness of a frequency characteristic in the high area of the direct sounds is improved and the sound quality can be widely improved.
