IPC: G02B15/16
Filed: 1985-04-19
Abstract: PURPOSE:To obtain a zoom lens which can secure a sufficient quantity of marginal light and whose aberration is satisfactorily compensated, by constituting the zoom lens of three lens groups and avoiding the variation of the entrance pupil by fixing the 2nd lens group against the image surface and moving the diaphragm together with the 3rd lens group in the direction, in which the 1st lens group moves, at the time of zooming. CONSTITUTION:The zoom lens of this invention is composed of the 1st lens group G1, 2nd lens group G2, and 3rd lens group G3 and a diaphragm S is united with the 3rd lens group G3 in one body. At the time of zooming,the diaphragm S moves together with the 3rd lens group G3 in the direction, in which the 1st lens group G1 moves, from a wide mode W to a telescope mode T and the 2nd lens group G2 is fixed against the image surface. When the zoom lens is constituted in such a way, variation of the interval between the 1st lens group G1 and diaphragm S and movement of the position of the entrance pupil can be reduced at the time of zooming. Therefore, problems, such as correction of distortion, securing of marginal light quantity, etc., can be dissolved.

Title: Method for cutting or punching electrode for lithium battery, and lithium battery having lithium electrode using the method
Inventor: YOSHIDA DAISUKE
IPC: H01M10/05
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To enable a lithium plate or a lithium alloy plate to be cut continuously so as to manufacture an electrode continuously by using a cutter or a punch having a blade tip coated with oxidation resistant oil. SOLUTION: A cutter 1 or a punch having a blade tip 2 coated with oxidation resistant oil having a viscosity of 50-500,000mm<2> /s, is used in a method for cutting or punching a plate material made of lithium or a lithium alloy for an electrode for a lithium battery into a predetermined shape. According to this cutting or punching method, no lithium adheres to the blade of the cutter or punch, so that the lithium plate or lithium alloy plate can be cut or punched continuously. If the viscosity is lower than 50mm<2> /s, the oxidation resistant oil is dripped from the blade tip 2 due to the low viscosity, thereby inhibiting formation of a coating film 5 on the blade tip 2.  In contrast, if the viscosity exceeds 500,000mm<2> /s, a quantity of the coating film 5 remaining on the blade tip 2 becomes large, so that the oxidation resistant oil adheres to the cutter or the like, which is not preferable from the viewpoint of mass production.

Abstract: PURPOSE:To control a data quantity of a compressed data in an excellent way by setting a control factor to be a prescribed constant when the compressed data obtained is at the outside of a prescribed range as the result of quantization compression by plural control factors. CONSTITUTION:Data quantities B1, B2 when a picture data is compressed by using control factors Q1, Q2 given in advance by encoding sections 3, 4 are obtained. An arithmetic section 5 obtains a control factor Q0 giving a data quantity B0 of an object compression data by means of linear approximation based on the value and an encoding section 7 uses the control factor Q0 to encode the picture data. When the data quantities B1, B2 are at the outside of a prescribed range, the control factors Q1, Q2 are set to prescribed constants. The prescribed range is selected to be a range of an information quantity generated by a 1st control factor and an information quantity generated by a M-th control factor as the result of plural trials of variable length compression encoding by using M kinds of control factors. Thus, the algorithm of compression is not destroyed to any picture.

Title: Motion suppressing device using hydraulic cylinder
Inventor: UEHARA KATSUHIRO
IPC: F16F9/43
Filed: 1989-03-31
Abstract: PURPOSE:To apply brakes to a moving element in good performance by furnishing an oil-hydraulic cylinder in such a way as getting over a stationary body and the moving body, and by allowing an accumulator to adjust the oil amount, which might be in excess or shortage due to difference in the section area between No.1 and No.2 oil-hydraulic working chamber, in the oil pressure chamber of the said cylinder. CONSTITUTION:An oil-hydraulic cylinder is provided as getting over a stationary and a moving element, and the oil in oil-hydraulic working chambers 5, 6 on the rod side and anti-rod side partitioned by a piston 4c is moved through a hydraulic circuit 7 with movement of the moving element. Because the oil passing through either of relief valves 8, 9 furnished in the hydraulic circuit 7 does not move unless its pressure rises above the set value on the applicable relief valve, this force becomes a resistance to restrict motion of the moving element. The section area of the working chambers 5, 6 is smaller on the rod side in the amount corresponding to the rod 4b, so that the excess of oil in the working chamber 6 on the rod side is accumulated in an accumulator 10. Accordingly the oil amount, which might be in excess or shortage due to difference in the section area between the working chambers 5, 6, can be adjusted to accomplish good performance of braking.
