Abstract: PROBLEM TO BE SOLVED: To make a photographing viewing angle at a wide-angle end include a standard photographing viewing angle and to obtain high optical performance over an entire variable power range by providing five lens groups, moving them so that an interval between specified groups may be increased or decreased in the case of varying power and making the refractive power of each group satisfy specified conditions. SOLUTION: This zoom lens is provided with five lens groups L1 to L5. In the case of varying the power from a wide-angle end to a telephoto end, the 1st, the 3rd and the 5th groups L1, L3 and L5 are moved to an object side so that the interval between the 1st and the 2nd groups L1 and L2 may be increased, the interval between the 2nd and the 3rd groups L2 and L3 may be decreased, the interval between the 3rd and the 4th groups L3 and L4 may be increased, and the interval between the 4th and the 5th groups L3 and L4 may be decreased. Assuming that the focal distance of an i-th group is (fi) and the focal distance of an entire system at the wide-angle end is (fw), the lens satisfies the conditions; 1.2<f1/fw<2.6, 0.4<|f2/fw|<1.2, 0.75<f3/fw<1.8, 0.95<f4/fw<2.4 and 0.6<|f5/fw|<1.7.

IPC: H01L23/28
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to avoid a complicatedness in the manufacturing process of a semiconductor device, such as a cutting of leads due to a stress, which is generated at the time of resin-sealing of the device, by a method wherein a polymerized plate is provided in a such a way as to oppose to a bed. SOLUTION: A second type of leads 2b are superposed on the opposite side to the side on one side of the sides of a semiconductor chip on a bed 3 via an insulating layer in addition to a first type of leads 2a and are wire-connected with pads 8b on the other side of the chip 8. Thereby, as the intervals between the first and second types of the leads 2a and 2b can be made wide, a distribution of the first and second types of the leads 2a and 2b is facilitated and the leads 2a and 2b are also formed comparatively short. As a result, as the leads 2a and 2b are also never cut by a stress, which is generated at the time of resin-sealing of a semiconductor device, and a processing of the leads 2a and 2b is also easy, a facilitation of the manufacturing work of the device can be contrived.

Abstract: PURPOSE:To shorten the executing time for calculation of the rotations carried out between i = 0 and (n) by using an arithmetic logic unit ALU for calculation of a partial sum, a fixed bit shifter, a register, and a rotation mode designating flip-flop. CONSTITUTION:In a 2nd cycle the rotation of i = 1 is calculated to a 1st pair of data groups and at the same time the rotation of i = 0 is also calculated to a 2nd pair of data groups respectively. In a 3rd cycle the rotation of i = 2 of the first pair, the rotation of i = 1 of the 2nd pair, and the rotation of i = 0 of a 3rd pair are carried out at one time. Hereafter the rotations are simultaneously carried out to the (n) pairs of input data groups in an n-th cycle in the same way and at the same time the final calculation results xn, yn and zn are obtained as the output values of the ALU na - nc against the 1st pair of data groups. Thus (m) pairs of initial input data x0, y0 and z0 are available. Under such conditions, the approximate answers of those vector rotations are obtained in the form of the executing time of (n+m-1)T, where (n) shows the bit numbers of (x), (y) and (z) respectively and T shows the cycle time of a basic clock.
