Title: Optical scanning device
Inventor: TANAKA YOSHIHIKO
IPC: G02B26/12
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To enable an optical scanning device to have such a configuration, that a worker can be prevented from erroneously detaching the screw of an adjustment leg after adjustment, by forming the outer shape of the lid body of an optical box while spreading it so as to cover the fastening member of the adjustment leg. SOLUTION: A screw 12b of an adjustment leg 12 and a fixing screw 13 to a main body frame are fastened in the same direction. The outer shape of a lid body 10a is spread so as to cover the screw 12b of the adjustment leg 12. At such a time, since the fixing screw 13 to the main body frame is required for attaching an optical box 10 to the main body frame or detaching it, the fixing screw 13 is prevented from being over the outer shape of the lid body 10a. Thus, when attaching the optical box 10 to the main body frame or detaching it, the worker is prevented from erroneously detaching the screw 12b of the adjustment leg 12, and a scanner can be provided not to deviate the irradiation position of the main body of scanner and since the unwanted screw is covered with the lid body, the work efficiency can be improved as well.

Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To maintain a trap function capable of quickly discharging a large amount of condensed water even when a valve is closed or the opening of the valve is impossible because of the failure of a temperature sensing member. SOLUTION: A valve casing is formed by connecting caps 4 and 5 to a main body 3 having an entrance 1 and an exit 2, a valve chamber 6 is formed in an inner side composed of the main body 3 and the cap 4 and a second valve chamber 7 is formed in an inner side composed of the main body 3 and the cap 5. A temperature sensing member 11 is arranged in the valve chamber 6 and a second temperature sensing member 21 is arranged in the second valve chamber 7. A spherical valve seat member 32 having a T-shaped valve port 31 formed between the temperature sensing members 11 and 21 is arranged so as to be freely rotated. When a large amount of condensed water is to be discharged, the valve seat member 32 is used by turning this to a position for communicating both of the valve chamber 6 and the second valve chamber 7 with the exit 2.  Normally, the valve seat member 32 is turned to a position for communicating the valve chamber 6 with the exit 2 and shutting off the second valve chamber 7 and the exit 2. When the temperature sensing member 11 fails, the valve seat member 32 is turned to a position for shutting off the valve chamber 6 and the exit 2 and communicating the second valve chamber 7 with the exit 2.

Filed: 1985-02-07
Abstract: PURPOSE:To detect easily the open loop gain of a feedback system by applying the disturbance to the feedback system and having comparison between the phase of the sum of optional two of the signals set before and after the adding point of disturbance and the disturbance signal and the phase of the remaining signal. CONSTITUTION:The output of an amplifier 1 to be measured is sent back to an input via a disturbance adder 3 through a feedback system. An oscillator 4 applies the disturbance signal of a specific frequency to the input of the adder 3 of the feedback system. The sum of optional two (input/output signals of the adder 3) among those three, i.e., the disturbance signal and the input and output signals of the adder 3 is obtained by a signal adder 5. Then the difference of phase between those two signals and the remaining one (disturbance signal) is applied to a phase comparator 2. Thus the output of a gain detector is obtained.

Abstract: PURPOSE:To compensate blur of contours and to increase the S/N ratio of a VTR by reversing the transfer characteristics of a line correlating circuit during reproduction with those of a detail emphasizing circuit in the vertical direction during recording. CONSTITUTION:A line correlating circuit during reproduction is provided with an 1-horizontal-line delay circuit 13 having a band wide enough to make even a video signal pass through it, a video limiter circuit 10, a subtracter 9, and an adder 14.
