Title: Semiconductor device
Inventor: TAKEGAWA KOUICHI
IPC: H01L23/50
Filed: 1979-07-18
Abstract: PURPOSE:To eliminate the spread of solders at the corners of a pellet and reduce the erroneous detecting operation of a fully automatic wire bonding work by forming a metallic surface of a carrier separately from the side surface of a semiconductor element at the corners of the element. CONSTITUTION:There is provided a lead frame 10 formed with cutouts 8, 9 at least at the two corners diagonally of an island 7. It is noted that the cutout shape may not be limited only to this but may also be formed under two corners corresponding to a pellet without an island. Then, they are ordinarily bonded, and the half-finished product is wire bonded by a fully automatic bonder. In this manner there exists no solder at the periphery of the pellet in the range of detecting in a fully automatic wire bonder but there are only pads and Al wires as a pattern to be detected as part of the pattern of solder to thus always detect a pattern of predetermined manner.

Title: Light propagating device
Inventor: FUJIMORI YASUTOMO
IPC: G02B6/02
Filed: 1986-04-21
Abstract: PURPOSE:To efficiently propagate light by providing a cylindrical member that forms a core part in which light is propagated and a supporting mechanism that forms a clad part by spouting gas to the circumference of the cylindrical member and supports the cylindrical member in non-contact state. CONSTITUTION:When air is injected from an injection device 3, the air is supplied to the supply port 5 of an air bearing 2 and enters a communicating chamber 6, and flows from the communicating chamber 6 to each air supplying chamber 7. When the air is injected uniformly form each nozzle 4, an optical fiber 1 is supported by injected air pressure in non-contact state. Thus, as the cylindrical member 1 is supported by air pressure, the cylindrical member functions as a core part, and ambient atmosphere of the cylindrical member 1, i.e. air, functions as a clad part. For instance, laser light propagates being totally reflected on the other peripheral face of the cylindrical member 1. Accordingly, the difference of refractive index between the cylindrical member 1 (core part) and air (clad part) is set large, and for instance, the laser light propagates in the cylindrical member 1.

Filed: 1987-04-16
Abstract: PURPOSE:To prevent the effect of turbulent flow caused at a time for rotating a chuck and to uniformize the coated amount of chemical liquid by providing uniform flow parts to a rotating front end part of the width direction of a holding face in the chuck holding a rectangular base plate. CONSTITUTION:The pressure between the bottom face of a groove 11 of the inside of an O-ring 13 and a rectangular base plate 1 is reduced by performing vacuum suction through a vacuum suction hole 12 and thereby the base plate 1 is fixed. Then when rotating a chuck 10 in the direction shown in an arrow A with a driving mechanism and applying a resist film on the base plate 1, turbulent flow is prevented from being caused in both sides of the base plate 1 especially in the space part of the rotating front direction by means of the uniform flow parts 15 provided to both sides of the base plate 1. Therefore a sufficient chemical layer can be uniformly formed even on the base plate 1 formed in a rectangular shape such as the base plate used for a thermosensitive recording head.

Abstract: PROBLEM TO BE SOLVED: To display difference pictures even for color pictures by providing a hue conversion means for converting a hue for 180 degrees for a picture element value for which at least one of R, G and B in the difference picture prepared by a difference picture preparation means is provided with a negative value, etc. SOLUTION: When the color pictures are inputted through picture input devices 1 and 2 and a network interface 3, a computer 4 defines the color pictures as I1 and I2 and prepares the difference picture Id (I1-I2) by performing positioning and obtaining a difference. Then, the computer 4 prepares the difference picture by performing the subtraction of the picture element value of the color picture I1 and the picture element value of the color picture I2' for which positioning is performed. In this case, when even one of the R, G and B is provided with the negative value, by performing control for converting the hue for 180 degrees, the R, G and B are all expressed by positive values. Thus, the difference picture is displayed as a normal picture.

Filed: 1991-03-30
Abstract: PURPOSE:To surely enable person existence to be judged regardless of the level of electrostatic capacity of the detecting object in a person detector capa ble of person detection according to the change in electrostatic capacity between a pair of electrodes. CONSTITUTION:The electrostatic capacity in a detection space between a pair of electrodes of a sensor Cx is converted to digital values by a detection circuit IC1 to be a capacity data.

Abstract: PROBLEM TO BE SOLVED: To eliminate a contact defect between the ground surface of a module substrate and a metal clip by forming an elastic louvered part in one body by cutting and raising a metal plate while pressing it against a hole bored in the metal plate owing to the cutting and raising. SOLUTION: When the metal part 201 having the louvered part 202 formed by cutting and raising so that it has elasticity is mounted on resin by integral molding while having the elasticity, the metal part 201 is fixed in a metal mold 203 while the louvered part is pressed against the hole formed in the metal part owing to the cutting and raising. Then the resin 204 is poured in the metal mold 203 in the pressing state to carry out integral molding. When the integrally molded component is taken out of the metal mold 203 after the resin cures, the louvered part restores itself almost to the position before the insertion into the metal mold by the elasticity of the louvered part made of metal. The cut part 202 comes into secure contact with a top and a reverse metal shield by the elasticity of the louvered part.
