Title: Power unit for automatic answering telephone system and the like
Inventor: IIJIMA TAKANORI
IPC: H04M1/65
Filed: 1988-03-31
Abstract: PURPOSE:To reduce power consumption by using a 2nd power supply which supplies continuously power to an internal circuit when the supply of power is stopped from a 1st power supply and a means which changes selectively the levels of the voltage supplied from the 2nd power supply in accordance with the state of the internal circuit. CONSTITUTION:In case an AC power supply has a service interruption, the output of an AC/DC converting circuit is not available yet. Thus a transistor TR7 is turned off with TR5 and TR4 turned on respectively and the power is supplied from a power supply 9. In this case, the supplied voltage is stabilized by the TR4-TR6, a Zener diode D3 and resistances R4, R7 and R8 respectively. When the level of the supplied voltage drops and a voltage detecting circuit 7 delivers 'L', TR8 and TR9 are turned off and the supply of power is stopped to an internal circuit. At the same time, a control means 11 transmits a signal of 'H' to the emitter of the TR8 and changes its own state to cope with a low voltage level.

Title: Electronic telephone set
Inventor: AKIBA TOSHIO
IPC: H04M1/31
Filed: 1988-04-04
Abstract: PURPOSE:To prevent unbalanced characteristic impedance of the entire telephone set and increase in the side tone by providing a breeder circuit connected in parallel with a dial circuit and receiving a mute signal. CONSTITUTION:The breeder circuit 7 connected in parallel with the dial circuit and receiving a mute signal is provided to the telephone set.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a projection optical system by making a distance shorter between a reflection type spatial modulation element and a projection optical system by projecting light of second and third colors in a first optical system, and projecting light of a first color in the second optical system. SOLUTION: Light R of a first color is made to pass by the side of a first filter 31, and made incident on a spatial modulation element 11. Light R of the first color modulated and reflected by the first spatial modulation element 11 is reflected by the first filter 31 and led to a succeeding group 21b of the first optical system 21, and projected together with the light G of the second color and the light B of the third color from an image formed by an image forming means. No optical element exists at all between a preceding group 21a of the first optical system 21 and a spatial image M, and between the second optical system 22 and the first spatial modulation element 11. Therefore, since it is possible to arrange the preceding group 21a of the first optical system 21 close to the spatial image M equivalent to the spatial modulation elements 12, 13, and arrange the second optical system 22 close to the spatial modulation element 11, this arrangement permits this system to be miniaturized.
