    Abstract: Disclosed is a head-mount type display apparatus having an optical system which is of the back-irradiation type by which the user can see an extremely high-quality video image and by which the user makes only in-focus adjustment thereby improving operation convenience. The head-mount type display apparatus includes at least two optical systems each including a light source, a LCD through which the light from the light source is passed, a reflecting plate which reflects the light passing through the LCD, a screen on the back side of which the reflected light from the reflecting plate is focused to form an image and a lens by which the light from the screen is focused to form an image at a viewing point, and a head-mount type member for supporting the two optical systems which are opposed to left and right eyes. According to the preferred embodiment, interference and distortion in the projected images arising from the image of the edges of the LCDs is substantially reduced.

    Abstract: A head-mounted display apparatus having an optical system which is of the back-irradiation type comprising at least two optical systems each including a light source (40L,R), a LCD through which the light from the light source is passed (41L,R), a reflecting plate which reflects the light passing through the LCD (43), a screen on the back side of which the reflected light from the reflecting plate is focused to form an image (44) and a lens by which the light from the screen is focused to form an image at a viewing point (45L,R), and a head-mount type member for supporting the two optical systems which are opposed to left and right eyes. According to the preferred embodiment, interference and distortion in the projected images arising from the image of the edges of the LCDs is substantially reduced.

    Abstract: PURPOSE: To prevent an adverse effect of a rapid change in the internal tempera ture of electronic equipment caused by the start or stop of a fan motor from affecting upon the characteristics or performance of electronic equipment by linearly changing the number of revolution of fan motor corresponding to the temperature to be detected. CONSTITUTION: When a power source switch is turned on, a CPU 40 inputs temperature data from an A/D converter 38 and calculates the required number of revolution of a DC fan motor 44. When the temperature value detected by a temperature sensor circuit part 37 is lower than the temperature set is advance, the CPU 40 controls the DC fan motor 44 to rotate the fan motor at a lowest rotatable speed. When the detected temperature value is within the range of temperature set in advance, the CPU 40 changes output data so as to linearly increase an output voltage and with this change, the number of revolution of the DC fan motor 44 is linearly increased. Namely, when the power source switch of electronic equipment is turned on, based on the temperature inside the electronic equipment, the number of revolution of the fan motor 44 is controlled to be linearly changed.

    Abstract: PURPOSE:To provide a video having extremely high quality in a state where the periphery of an LCD is inconspicuous to a user by making the optical system of a display device of head mounting type a back projection type, and to prevent the user from feeling troublesome because adjustment is only focusing. CONSTITUTION:This device is provided with an optical system having a light source 40, the LCD 41 which transmits light from the light source 40, a reflector 43 reflecting the transmitted light from the LCD 41, a screen 44 on which reflected light from the reflector 43 is formed into an image from a back side, and a lens 45 deciding the image-formed position by the transmitted light from the screen 44; and a member for attaching a device to a head which holds at least two optical systems corresponding to right and left eyes.

    Abstract: PURPOSE:To provide a device where the elapse time of a video monitor is displayed on a video monitor display part. CONSTITUTION:When a display instruction is inputted to a microcomputer 1 incorporated in the video monitor, bar display and time display are outputted and are mixed with the output of an RGB decoder 3 and are superimposed on a monitor picture 4 to display the elapse time. When a power-off instruction is inputted, time data counted in time units by a counter of the microcomputer 1 only at the time of using a device is written in a memory 5. When a power-on instruction is inputted again, time data is read in from the memory 5, and the elapse time is added, and the elapse time is displayed again on the picture 4 based on the time resulting from this addition.
