Abstract: PURPOSE:To display analogically the result to count with simple constitution by providing an adder circuit, two reset means interlocking with each other and a circuit holding a maximum value of the addition voltage of the adder circuit and using the output of the said holding circuit as the 2nd input of the adder circuit via an LPF. CONSTITUTION:After reset is finished by the switching of interlocking switches 105, 110, the 1st error detection pulse having a voltage Vp is inputted to the adder circuit 101. In this case, since the output of the LPF 102 is 0, the voltage of the said pulse appears as it is at the output of the circuit 101 and a capacitor 104 of the peak hold circuit 107 is charged and held up to a voltage Vs being the subtraction of a forward voltage VDS of the diode 103 from the voltage Vp. Since the LPF 102 has a slow leading characteristic, the output voltage of the circuit 107 approaches gradually the Vs. The output is fed back to the circuit 101. Then the output voltage of the circuit 107 rises as Vs, 2Vs, 3Vs... at each generation of the error detection pulse. The output is displayed analogically on a voltmeter 116 via a peak meter circuit 115.

Title: Optical element
Inventor: YUASA SATOSHI
IPC: G09F9/30
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a distinct image having high contrast and resolution and to eliminate the limitation in angle of field by sandwiching a gel layer which exhibits light transmittance by heating and exhibits light scattering property by cooling between a pair of substrates formed with heating elements on the surface of at least one substrate. CONSTITUTION:The distribution of polymer molecular chains exists dividedly in a coarse region and dense region in the state (low-temp. stage) in which the gel layer 2 is not heated and therefore the incident ray 6-2 on the low-temp. region 4a of the gel layer scatters (diffuses). On the other hand, the gel layer in the region in contact with or proximity to the heated part is also heated and the polymer molecular chains are uniformly distributed in average when the prescribed position of an IR absorption layer 8 is heated from the outside by the irradiation of, for example, an IR beam 5 according to an information signal. The incident ray 6-1 on the heated region 4 of the gel layer 2 passes therefore approximately straightly through the gel layer 2 and is emitted therefrom. The heated region 4 restores the original non-transparency when the temp. falls.
