Title: Semiconductor integrated circuit device
Inventor: NASU SHIGENORI
IPC: H01L23/50
Filed: 1990-01-24
Abstract: PURPOSE:To restrain an fragile alloy layer from being formed by a method wherein a barrier metal layer is provided between a Cu containing metal layer and an Sn containing metal layer which constitute an external electrode that leads the electrode of a circuit element enveloped in a package out of the package so as to restrain Cu atoms and Sn atoms which form the metal layers from diffusing. CONSTITUTION:A barrier metal layer 3c is provided between a base Cu plating metal layer 3b and a solder plating layer 3d which constitute an outer lead so as to restrain Cu atoms and Sn atoms which form the metal layers from diffusing. By this setup, a Cu-Sn alloy layer rigid and fragile, which used to be usually formed between the base Cu plating metal layer 3b and the solder plating layer 3d in a heat treatment performed in the manufacture of a semiconductor integrated circuit or the aging of it, can be retrained from being formed, and troubles such as the separation of a plating layer or poor solderability caused by a Cu-Sn alloy layer can be lessened.

Title: Slip verifying device
Inventor: KOSHIDAKA TERU
IPC: G06T7/00
Filed: 1984-01-28
Abstract: PURPOSE:To facilitate visual verification of signature by reading at least seal print out of a slip having seal print and signature by an image reader, collating automatically with retrieved registered seal print displaying registered signature. CONSTITUTION:When an operator sets a slip ID to be collated on a hopper HP, information (account number) and seal print on the slip are read by the image reader 25 and sent to a preprocessing section 26. The preprocessing section 26 takes out the seal print part and sends to a collating memory 27, and sends account number part to an OCR29. The OCR29 recognizes the account number and sends it to a file retrieving section 1 through an interface, and retrieves registered seal print and signature from a registration file 10. A collating and operating section 28 collates collated seal print and registered seal print and calculates collation rate and determines the result of automatic collation. Even when the result of automatic collation is negative, visual collation is performed, and in case of OK, corresponding registered signature is indicated in a display 23b. This is visually compared with collated signature on the slip, and its adequacy is judged, and reported to a controlling section 20 from a keyboard 24.

Title: Floppy disk storing device
Inventor: KITANO TAKAMASA
IPC: G11B33/02
Filed: 1989-01-24
Abstract: PURPOSE:To prevent the action errors and the destruction of the recorded information written into a floppy disk by adding the guard members having the approximately height to an operating push button to the both side of this button set on a front panel. CONSTITUTION:The guard members 3A and 3B having the approximately equal height to an ejection button 4 are added to the both sides of the button 4 set on a front panel 3. The panel 3 also has an inserting port 3C for a floppy disk 1. In this case, the button 4 protrudes with insertion of the disk 1 into a floppy disk storing device 2. Thus both members 3A and 3B protect the protruded button 4. Thus it is possible to prevent such a trouble where the disk 1 is ejected by mistake due to a fact that the button 4 is pushed by a misoperation, etc., in a read/write mode of the recorded information. Thus the action errors and the destruction of the recorded information written into the disk 1 can be prevented.

Title: Camera
Inventor: TAMADA KAZUMASA
IPC: H04N5/232
Filed: 1995-01-31
Abstract: PURPOSE: To use an optical finder in response to the mode by providing a mode for usual focus adjustment by an automatic focus device and a mode hardly causing an out of focus. CONSTITUTION: A revision range of a focal distance of a zoom lens 10 is limited to be a prescribed zoom magnification by a zoom limit means and the drive range of a focal lens 106 by an automatic focus means is limited by a focus limit means. That is, when the conversion range of the focal distance of the zoom lens 10 is limited in the optical finder mode (mode hardly causing out of focus), the drive range of the focus lens 106 is limited within a prescribed range. Thus, when an image pickup distance is within a range of 1m to infinite, out of focus is not easily caused and the method is suitable in the case of using an optical finder 12 whose out of focus cannot be especially confirmed. Furthermore, the automatic focusing is made stable by limiting the drive range of the focus lens 106.
