Title: Lens barrel
Inventor: NOMURA HIROSHI
IPC: G02B7/10
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To sustain an impact from a forward direction even in the case the lead of a helicoid in the advance and retreat mechanism of a lens barrel is large and to keep respective parts from being broken by providing a cam barrel with an impact receiving surface engaged with the follower of a follwer barrel at the rear end of the cam groove of the cam barrel. SOLUTION: In a condition that the lens barrel is at a position where the lead is zero and where a clutch can not function, a ring member 18b projected from a lead groove 17b to the outside approaches to the impact receiving surface 17m of a straight advance guiding barrel 17. Therefore, even when the impact is given in such a condition, the ring member 18b abuts on the firm impact receiving surface 17m, and the surface 17m surely sustains the impact, so that the respective parts are not broken. Thus, even when the lead of the helicoid of the advance and retreat mechanism of the lens barrel is large, the impact given to the lens barrel from the forward direction is surely sustained and the respective parts are kept from being broken.

Filed: 1990-02-15
Abstract: PURPOSE:To facilitate the selection of the operating mode and the recognition of the operating mode by displaying a character representing the selected operating mode distinguishingly from a character representing other operating mode and extinguishing the character representing other operating mode after lapse of a prescribed time. CONSTITUTION:When an operation changeover switch 4 is depressed at a time t1, an input presence discrimination section 21 outputs a pulse signal. Moreover, an operating mode judging section 22 gives a signal corresponding to 'heating' to a display control section 24 and a timer section 23 outputs a signal being at L for 1 second and H for 1 second thereafter twice in total. Then the display control section 24 gives a mode designation signal and a pulse signal going to H twice only to a liquid crystal drive circuit 9. After a time t2 of lapse of 4sec from the time t1, only the display of 'heating' is lighted and a heating operation mode signal is sent from a remote controller 2 to an indoor equipment 1. Thus, the selection of the operating mode is facilitated and which operating mode is easily recognized.

IPC: G09G3/28
Filed: 1995-02-23
Abstract: PURPOSE: To prevent a video display device from being collapsed by the impression of a high voltage current on a driving circuit or discharge cell due to malfunction by operating a high voltage supply only when a control circuit like a central control circuit is normally operated. CONSTITUTION: Clock detecting circuit 7 detects the clock and outputs positive logic when a clock is outputted from a central control circuit 6. And a voltage necessary for discharge is impressed across anode and cathode of the discharge cell and electricity discharges at the instance when the 1st switching element 2 and the 2nd switching element 4 are switched simultaneously. However, in the case that a low voltage power supply is not generated at the time of switching on the commercial power supply 15 or the central control circuit 7 outputs no clock, the clock detecting circuit 7 outputs negative logic and does not operate the power control integrated circuit 11. Therefore, even in the case that control circuits 3 and 5 fix the switching elements 2 and 4 to a switching state, no voltage is generated on the secondary side of the power supply transformer 9.
