Title: Lead frame of semiconductor and its preparation
Inventor: KAN KIYOHIDE
IPC: H01L23/495
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To increase the moment of inertia, with respect to the cross-sectional area of a punch and a lead frame to improve the strength by forming the design of a lead wire located at the center between two die bars, so that the lead wire is bent for a number of times at a predetermined portion. SOLUTION: A lead wire is bent just by predetermined angles θ1 , θ2 at a point of not more than half the distance from a lead chip 104 to a die bar 15, and a punch 101 is formed into such a shape that the cross-sectional area increases, until the length of the lead wire becomes half from a portion of the lead chip 104, corresponding to a lead end portion on the side close to a pad portion 11. In the case where press punching is carried out by the punch 101, leads 102, 103 formed on both sides of a centerline X-X' have such shapes so as to be bent by a predetermined angle, and the moment of inertia obtained in the case where the cross-sectional area is increased approximately twice. Therefore, in the case of the punch having the same length and width, the strength increases approximately twice as the cross-sectional area increases.

Abstract: PURPOSE:To shorten a development period by a method wherein a program or a logic is decided, which controls a CPU as writing or erasing an information in an EPROM mounted on a first semiconductor integrated circuit device, the EPROM of the first semiconductor integrated circuit device is converted into a mask ROM, and a second semiconductor integrated circuit device, in which a program determined by the mask ROM is written in, is formed. CONSTITUTION:A floating gate electrode, which is peculiar to a field effect transistor as a memory cell of a memory cell array M-ARY EPROM, is removed to constitute a mask ROM which makes a field effect transistor of a single layer gate electrode structure serve as a memory cell. That is, in the EPROM, as the floating gate electrode is formed of a first layer gate electrode, a forming process of the first layer gate electrode is eliminated when the EPROM is substituted with the mask ROM. Each circuit block other than a read only memory(ROM) block is composed of a second layer gate electrode, so that the change in structure or electrical property due to the replacement of the EPROM with the mask ROM is prevented.

Abstract: PURPOSE:To expand the reception range of the receiver receiving a small power transmission radio wave while maintaining the quality. CONSTITUTION:Modulation signals D1, D3, and D5 of reception means 110, 310, and 510 are weighted by multiplication means 14, 34, and 54 using reception quality signals C1, C3 and C5, made into D1C1, D3C3, and D5C5. By adding reception quality weighting modulation signals using the first addition means 74 of an integration means 70 they are made into the first signal (D1C1+D3C3+D5 C5). The reception quality signal is added by the second addition means 84 of the integration means 70 to make the second signal (C1+C3+C5). The signal obtained by subtracting the first signal by the second signal in a subtraction means 75 is taken as an output modulation signal. By integrating the modulation signal without integrating a high frequency signal of the reception antenna, a good modulation signal can be selectively obtained while maintaining a small loss and easy wiring.

Abstract: PURPOSE:To restrain density unevenness of an image and to obtain a copy corresponding to density of every part of an original by detecting original density, sampling data at prescribed intervals, and computing them. CONSTITUTION:The differences between the computed average value of light quantity and each data stored in an RAM are computed and the results are distributed to the address spaces of the RAM. The voltage to be applied to a light source or developing bias is decided in accordance with the average value. When exposure is started, the differences with the average value stored in the RAM are read out in succession in synchronism with store timing, and the differences are multiplied with a proper coefficient. The obtained value is added to or subtracted from the voltage to be applied to the light source and obtained from the average value before, and the light emission quantity of the light source or developing bias is thus controlled to obtain proper copy densities on every part of the copy, thus permitting formation of a copy corresponding to every part of the original.
