Title: Optical information recording carrier
Inventor: MIURA KYO
IPC: G11B7/24012
Filed: 1986-09-03
Abstract: PURPOSE:To permit optical recording or reproduction of information without disposing an illuminating optical system by laminating electrodes, light emitting layer which emits light in accordance with external energy and pattern layer on which the patterns based on recording information are formed successively on a substrate, thereby consti tuting a tilted carrier. CONSTITUTION:This recording carrier is formed by laminating the electrodes 22, 22a for supplying the external energy, the light emitting layer 24 which emits light in accordance with the external energy and the pattern layer 23 on which the patterns based on the recording information is formed successively on the substrate 21. The light emitting layer 24 emits light when the energy; for example, electric energy, is supplied to the electrodes 22, 22a from the outside. The luminous flux emitted from the light emitting layer 24 is discriminated in the pattern to a light transparent part and light shielding part according to the recording information and is projected onto the pattern layer 23. The recording information can be read by projecting the luminous flux transmitted through the pattern layer to a sensor array provided above the pattern layer 23. The need for the illuminating optical system such as light source or lens system to illuminate the recording region is thereby eliminated and the reduc tion in the size and weight is permitted.

Title: Focusing range setting method
Inventor: TANAKA HITOAKI
IPC: G02B7/09
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To adjust a focus lens system in accordance with the position of a zoom lens system so that a focusing range may be constant by setting the focusing range by the focus lens system based on the combination of the position of the zoom lens system and the position of the focus lens system which attains a fixed focusing distance. SOLUTION: A focus control part 32 somewhat moves the focus lens system 21A in an optical axis direction according to a focus control signal CONTAF in focusing processing. At such a time, an evaluated value (differential value of a luminance signal) S31 supplied from an AF processing part 31 gets higher as a subject image to be picked up gets nearer to a focusing state, and it gets lower as the subject image goes farther from the focusing state. The moving direction of the lens system 21A capable of making the subject image in a focused state is discriminated by the part 32 based on the moving direction of the lens system 21A and the change of the evaluated value in accordance with the moving direction.

Title: Zoom lens
Inventor: KAMAI TAKASHI
IPC: G02B7/10
Filed: 1993-07-29
Abstract: PURPOSE:To control and display an f-number and the focal distance of a lens corresponding to modes having different aspect ratios.

Title: Facsimile equipment with call reservation function
Inventor: FUTAGAWA YASUNARI
IPC: H04N1/32
Filed: 1986-09-03
Abstract: PURPOSE:To allow an operator to quickly recognize a call request sound during facsimile communication by permitting a same sound emitting body to ring a call sound when a call comes in and is made and requested and distinguishing an alarm sound different from the call sound. CONSTITUTION:If a call reservation is made during facsimile communication, a switch in a switch box 33 is changed over to the side of a line transformer 31, and a control signal from a control part 27 changes over a switch in a switching circuit 37 to the side of a DC power source 41. A simultaneously supplied call request signal is supplied as an intermittent signal to an incoming call generator circuit 38 by the ON and OFF controls of a switch circuit 40, and the sound emitting body 39 rings an intermittent call request sound based on a call signal. Since the switching circuit 40 controls the intermittent ringing of the call request sound, the intermittent period can be set freely. As the tone of the call request sound is the same as that of the incoming sound, the alarm sound ringing when a facsimile abnormally operates can be clearly distinguished from the call request sound by their different tones.
