Abstract: A projector apparatus includes digital micromirror device (DMD) Color temperature and adjustment of white balance with respect to projection light can be detected in a light condition in a convenient manner. A position of the picture formed by the projection light on the screen can be shifted. A projector apparatus includes a shutter disposed downstream of the projection optics for blocking the projection light and a sensor attached to the shutter. In a second embodiment, a projector apparatus includes a sliding structure for causing a projection optics to be slid relative to a casing constituting an apparatus body in a perpendicular relation to the optical axis of projection optics means and a follow-up structure for causing a sensor to follow the projection optics means.

Abstract: Provided is an apparatus for supplying standby power which comprises a means for supplying standby power based on a solar cell and another means for supplying standby power based on an industrial/domestic power supply, wherein the two means are selectively used by switching. The apparatus aims at saving, as much as possible, the energy consumption by the supply of standby power from the industrial/domestic power supply while maintaining the supply of standby power. The apparatus further aims at avoiding that, when the supply of standby power is switched between the two standby power supply means, data present at that instant in a personal computer to be supplied with the standby power and/or preset information stored in a microprocessor incorporated in an electric/electronic device will disappear.

Abstract: A rotary manipulating apparatus of a rotary type of which the action can be conducted with a definite sense of use is provided for, when installed in an electric or electronic instrument, simplifying the packaging of the electric or electronic instrument with packaging materials shaped and arranged not intricate and minimizing the damage in case that the instrument in the packaging suffers from any accidental collision during delivery. The rotary manipulating apparatus includes a base 3 for mounting to the instrument, a manipulating means 4 for carrying out a rotating action, and a movable means 5 provided between the base 3 and the manipulating means 4 for slidably moving the manipulating means 4 or an input rotary shaft 6 for actuating the manipulating means 4 along the axial direction in relation to the base 3.

Abstract: A projector apparatus comprising a digital micromirror device (DMD) means is disclosed. According to this apparatus, it is possible to carry out the detection of color temperature and the adjustment of white balance with respect to the projection light in a light condition in a convenient manner. It is further possible to shift the position of the picture formed by the projection light on the screen. A projector apparatus (1) is constructed comprising a shutter (7) disposed downstream of the projection optics means (6) for blocking the projection light and a sensor means (8) attached to the shutter (7). Another projector apparatus (1a) is constructed comprising a sliding means (18a) for causing a projection optics means (8a) to be slid relative to a casing (2a) constituting the apparatus body in a parallel relation to the optical axis of the projection optics means (8a) and a follow-up means (19a) for causing a sensor means (10a) to follow the projection optics means (8a).

Abstract: A recording/reproducing apparatus (100) for recording a received signal as digital data in a file format and for reproducing the digital data stored in the file format is disclosed. A control means (101) carries out such a control in the recording mode that the digital data continuously received and stored in a buffer memory (150) is stored in a storage means (160) at a writing speed which is higher than a speed at which the digital data was stored in the buffer memory (150), while being divided into files in response to a division command from a manual input means (110).

Abstract: There is disclosed a system for inputting speech that comprises an echo canceller section 120 for subtracting a pseudo echo signal, generated by an adaptive filter 121 based on a speech signal inputted to a first input terminal 120a, from a speech signal for sending as inputted to a second input terminal 120b to thereby remove echo components contained in the speech signal for sending; a main microphone 151 for mainly receiving sound from an objective sound source; a reference microphone 152 disposed a predetermined distance apart from the main microphone 151 for mainly receiving sound from other than the objective sound source; and an audio delay section 180 for giving a predetermine delay to the speech signal for sending from the main microphone 151.

Abstract: A radio facsimile interface unit is connected between a radio set provided with a speaker and a facsimile machine and also connected to a microphone stand provided with a microphone and a manually operable transmission switch. The interface unit is so structured to allow the radio set to carry out an ordinary audio communication using the speaker and the microphone. The radio set is normally set in a reception mode and the transmission switch is depressed only when audio information is to be transmitted. The interface unit is provided with a relay between the microphone and the radio set and the relay is disconnected when the facsimile is in a transmission mode, so that facsimile communication is given a higher priority than audio communication.

Abstract: A compact disc case including lower and upper cases fixed by snap joints with enough space left in between for storing a compact disc. The lower case has at least three cushion holders to support the compact disc up above the bottom, and for preventing improper insertion of the case into a disc player, a control groove or a control shell is provided at least in either one of the upper and lower cases. The front edge wall of the lower case is provided with engagement holes, while the upper case has pawls to be engaged with the engagement holes, and also latches and latch locks engaging with each other are formed at the rear of the upper and lower cases. By means of this structure, the case with a compact disc in it can be inserted into a disc player for use without any improper insertion, and since the upper and lower cases can be readily detached from each other, the disc can be taken out and cleaned easily when the information-recording side gets dirty due to long periods of use or by accident.
