Title: Eyepiece lens system
Inventor: KANAI MORIYASU
IPC: G02B25/00
Filed: 1995-01-10
Abstract: PURPOSE: To lengthen the eye relief by composing a Kellner type eyepiece lens system so as to satisfy a specified condition. CONSTITUTION: This system is composed, in order from the object side, of a positive single lens 11 and a joined lens 12 of positive and negative lenses. The Kellner type eyepiece lens system satisfys the conditional relations: (1) d<0.3f, (2) f1 >1.5f. In this case, d: an air gap between the positive single lens 11 and the joined lens 12 of positive and negative lenses, f: the focal distance of the whole system and f1 : the focal distance of the positive single lens 11. When (d) exceeds the upper limit of the conditional relation (1), the incident height of a peripheral light beam on the joined lens 12 of positive and negative lenses is lowered and the eye relief is not made to be sufficiently long.  When the focal distance f1 of the positive single lens 11 is decreased below the lower limit of the conditional relation (2), the power of the positive single lens becomes too large, the incident height on the joined lens 12 of positive and negative lenses is lowered since the peripheral light beam is strongly bent in the direction of the optical axis by means of a visual field lens and the eye relief is shortened.

Filed: 1987-01-08
Abstract: PURPOSE:To easily select an optimum point of the reception state by controlling an antenna by switching successively or automatically according whether, the reception state of the antenna is displayed on a screen or not with respect to a remote control television to which an indoor antenna is attached. CONSTITUTION:When a channel is selected by channel remote control, a microcomputer 14 outputs a defeat pulse 15 to a control circuit 16 and fixes a control line 23 to the high level on the automatic selection side. Then, the control circuit 16 operates a gate pulse generating circuit 4, a noise amplifying and detecting circuit 3, a coincidence pulse generating circuit 5, a frequency demultiplier 18, and a counter decoder 10 to automatically search an optimum reception state. When the same channel is selected next, the selection state of the antenna is displayed on the screen, and defeat pulse 15 directly operates the counter decoder 10 because the control line 23 is fixed to the low level on the successive switching side. Thus, the reception condition can be selected on the screen by repeat of selection of the same channel.

Title: Communication station
Inventor: KIRA HIROFUMI
IPC: H04L1/22
Filed: 1981-01-07
Abstract: PURPOSE:To realize a change-over system between a normally used transmission line and a stand-by transmission line which automatically switches the normally used line to the stand-by line when the normally used line is in troubles, by installing a means which detects interruptions of input signals. CONSTITUTION:When a circuit trouble occurs in the A-system trnsmission line LA among A- and B-system transmissione lines LA and LB connected to a change-over switch S1 of a communication station, an integrating circuit (abef) of a change-over controlling section (abe) works and an integral output INT is lowered after a prescribed time. At this time, an one-side differentiating circuit (abeg) works and its differential output TRG is given to a flip flop circuit FF as a trigger pulse. Since the B-system transmission line is under a normal condition, only a B-system remote change-over signal BCH is supplied to the flip flop circuit FF as a reset signal, and the flip flop circuit is set to a reset condition. Therefore, the change-over switch S1 is switched to the B-system transmission line which works as a stand-by transmission line.
