IPC: H04N9/87
Filed: 1995-06-08
Abstract: PURPOSE: To save power consumption of an encoder by individually stopping three D/A converters for each of a composite signal, a luminance signal and a chroma signal according to the conditions of a video equipment. CONSTITUTION: When digital RGB signals from terminals 2, 3 and 4 are inputted in a conversion circuit 6, the circuit converts these digital signals and outputs a digital composite signal SD, a luminance signal YD, and a chroma signal CD to a line 7, a line 8 and a line 9, respectively. Each of D/A converters 16, 17 and 18 converts each inputted signal and outputs an analog composite signal SA, a luminance signal YA and a chroma signal CA, respectively. A semiconductor switch 22 switches a contact to an (a) side (power supply + B is supplied to all the D/A converters) or a (b) side (power supply + B is not supplied to the D/A converters 17 and 18) in accordance with the mode signal to be given to a control terminal 23. Because a liquid crystal monitor does not simultaneously require three signals of SA, YA and CA, the power saving of a portable equipment becomes possible.

Title: Disk tray device
Inventor: HIRAKUI KATSUYA
IPC: G11B17/04
Filed: 1988-06-09
Abstract: PURPOSE:To prevent a detecting switch from being damaged even when the moving locus of a driving piece coincides with the detecting switch by providing a protrusive member neighboring to the movable contact of the switch in the case of inserting a disk tray from an insertion opening and assembling it. CONSTITUTION:At the time of working the assembling of the disk tray 20 and an equipment main body 11, the whole of the disk tray 20 is inserted from the insertion opening. At this time, the passing locus of a hook member 21 is evaded from being brought into contact with the movable contact compulsorily by the protrusive member 40. In other words, the protrusive member 40 displaces the head part of the hook member 21 in a direction to insert the disk tray 20. However, the hook member 21, after passing the protrusive part 40, is recovered by its own elasticity, and is connected on the protrusive member 40 when it is moved in a draw-out direction. Therefore, by providing the protrusive member 40 neighboring to the tip of the movable contact 301 of the switch 30, it is possible to assemble the disk tray 20 and the equipment main body when they are assembled by preventing the hook member 21 from crashing against the movable contact 301 on the moving locus of the hook member 21.
