Patent JP-H04179908-A (JP)
Title: Small-sized real image type variable power finder
Inventor: ISHIZAKA SATORU
IPC: G02B15/167
Filed: 1990-11-15
Abstract: PURPOSE:To shorten a movable part and to improve visibility by forming this finder of an objective lens part which varies power by moving 2nd and 3rd lens groups and an ocular part and making the focal distances of 1st and 2nd lens groups of the objective lens part satisfy a specified conditional expression. CONSTITUTION:The 1st to the 3rd lens groups are provided with negative, positive, and negative lens groups in order from an object side. The object lens part which varies the power by moving the 2nd and the 3rd lens groups and the ocular part are formed, and the focal distances of the 1st and the 2nd lens groups of the objective lens, is made to satisfy the conditional expression of 1<¦f,¦/f2<1.2, supposing that the focal distances of the 1st and the 2nd lens groups are f1 and f2, respectively. The power is varied by principally moving the 2nd lens group and the movement of an image surface with the variable power is corrected by moving the 3rd lens group. Since the movement of the 3rd lens group hardly contributes to the power varying action, the 3rd lens group only has to have weak power by which the movement of the image surface is corrected. Thus, the entire length obtained at the time of assembling the finder in a camera is shortened and the visibility is improved.

Filed: 1992-11-17
Abstract: PURPOSE:To improve the accuracy by providing a reference voltage circuit and a D/A converter to set an upper limit reference voltage and a lower limit reference voltage of an A/D converter, and a detection circuit for a white level minimum output so as to set shading correction within a range of dispersion in a white level. CONSTITUTION:A switch(SW) 1 is set to a reference voltage circuit 24 and a D/A converter 28 is used to set a lower limit reference voltage VREF- of an A/D converter 25 to 0V. A Dc recovery circuit 21 eliminates a DC component in a white waveform picture information set from a CCD 11, a variable gain amplifier 22 amplifies the resulting signal without any gain and the A/D converter receiving the resulting amplified signal at its terminal VIN quantizes the signal in a range of 0-reference voltage. In this case, a minimum value detection circuit 28 detects a minimum output, the SW 1 is then thrown to the position of a peak hold circuit 23, and the A/D converter 25 receiving the white waveform quantizes the input signal in a range of a minimum - a maximum output. The amplification factor of each picture element is obtained based on the data above and the result is stored in a memory 27 as white waveform dispersion data and the data are transferred to the amplifier 22 for each picture element when an original is read. Thus, shading correction with high accuracy is executed.

Title: Bump stopper
Inventor: HASEGAWA MITSUHIRO
IPC: F16F9/58
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To simplify structure so as to reduce a cost by composing a bump stopper of a load receiving part and a connecting part making connection to the upper end of a cylinder body possible, and forming the load receiving part and connecting part integrally by press working of raw material. SOLUTION: A bump stopper 5 exists as one component by integrally forming a load receiving part 51 and a connecting part 52 by press working of raw material. This bump stopper 5 forms specified bump stopper structure together with a bump cushion by being connected to the upper end of a cylinder body 11, that is, a bump stopper fitting member 14, after fitting a spring guide to the periphery of the cylinder body 11. When a shock absorber 1 is most compressed, this bump stopper structure impedes further compression by bringing the bump cushion into contact with the bump stopper 5 and relaxes shock associated with this impediment of compression. Structure is therefore simplified to reduce cost.
