Title: Manufacture of lead frame for semiconductor device
Inventor: FUJITA KATSUFUSA
IPC: H01L23/50
Filed: 1993-11-16
Abstract: PURPOSE: To provide the manufacture of a highly reliable lead frame by preventing bubble generation between the terminal leads so as to maintain terminal lead alignment accuracy at the time of forming a dam bar using insulating photo-setting solder mask resist on the terminal lead and improving chemical resistance of the resist between the leads. CONSTITUTION: Unnecessary parts are removed from metal conductive strip material so as to allow the leading edges of inner leads 13 to be connected, and the continuous body of lead frames in intermediate shape is provided. A thin layer of solder mask resist is applied to the prescribed parts on the top and bottom planes on the terminal lead 16 of the continuous body, and the resist pattern for a frame-shaped clam bar 18 is formed on the top and bottom face of the resist by exposure. Then, after forming the frame-shaped dam bar by developing and removing the unexposed parts (unhardened parts) by peeling, the terminal lead 16 is processed to have a prescribed length, and the connection at the leading edge of the inner lead 13 is cut. Thus, the lead frame which has the dam bar 18 at the prescribed part on the terminal lead 16 is provided.

Title: Method for imaging for lithographic printing without fault caused by static electricity
Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To remove a fault caused by a static electricity by reducing dielectric properties of each plate layer, lowering a voltage by stored charge as a minimum limit, decreasing possibility of generating an arc, and using a conductive film as a plate base. SOLUTION: A plate 100 is constituted of an image region 110 and non-image regions 112, 114. The region 114 has an uppermost layer 120 selected with respect to affinity in a lithographic printing meaning of a connected state to both clamps 105a, 105b, an ablation layer 125 of an imaging layer selectively destroyed with an imaging radiation, and a base 120 having an affinity reverse to that of the layer 120. A plate is appeared as a slotlike gap 135 for receiving an ink at a position where the layer of the base 130 is developed by imaging. A series of visible faults 150 exhibit positions for generating an arc to reduce a dielectric strength between a charged surface and a ground potential by setting the base 130 to a dielectric or semiconductive property.

Title: Wiring formation
Inventor: INOUE RYOZO
IPC: H01L23/52
Filed: 1991-11-27
Abstract: PURPOSE:To form a wiring of two-layer structure having resistance to both EM and SM without corrosion and complication of a process by making a wiring amorphous and by thermally treating it thereafter. CONSTITUTION:After a wiring thin film is formed on a foundation insulating layer 4, it is processed to a specified pattern and a wiring layer 1 is formed. A crystal grain diameter of the wiring layer 1 in the process depends on thermal treatment conditions after film formation; approximately, it is an order from several tenths of mum to several mum. Then, ion implantation is performed, and crystal grain boundary is broken as far as about half a depth of a thickness of the wiring layer 1 and an amorphous layer 3 is formed. Thereafter, heat treatment is carried out at about 400 deg.C for about 20 to 30min, the amorphous layer 3 is recrytallized and the wiring layer 1 is formed to two-layer structure. Since the formed wiring layer 1 does not have a bamboo grain boundary which thoroughly crosses inside a wiring due to its two-layer structure and each of an upper layer and a lower layer has bamboo structure, both EM resistance and SM resistance can be improved.

Filed: 1994-12-16
Abstract: PURPOSE: To provide a converter including a barrel selector for selecting a specific bit field in several possible bit fields for further operating a processing related with a data converter such as an encoder or a decoder. CONSTITUTION: A data converter (for example, 10, 90, and 92) for converting a signal from one form to another converts a signal from analog-to-digital, or from digital-to-analog form. This converter has an analog side and a digital sample side. A programmable barrel shift selector (for example, 34, or 80) at the digital sample side receives digital signal samples with a first bit field width, and selects a second bit field width as an output. The second bit field width is programmable over a certain range to selectively determine which bits in the first bit field are included in the second bit field.

Title: Solid substance having antimicrobial action, its production and antimicrobial action on liquid and its flow channel
Inventor: HAYAKAWA MAKOTO
IPC: B01J27/10
Filed: 1994-11-10
Abstract: PURPOSE: To obtain a solid substance capable of minimizing the elution rate of silver and thus maintaining antimicrobial action for a long period of time. CONSTITUTION: This solid substance having antimicrobial action is obtained by forming a layer comprising silver particles on the surface of a substrate through a layer having a photocatalytic action on the substrate or forming the layer comprising the silver particles on a carrier having photocatalytic action and further making at least partially a slightly soluble silver salt (preferably silver chloride) on the surface of the layer comprising the silver particles.  The antimicrobial agent comprising particles containing silver element supported through the layer having photocatalytic action on the substrate or the antimicrobial agent comprising particles containing the silver element supported on the carrier having photocatalytic action is immersed in a solution having >=30ppm and <3,000ppm chlorine concentration and the slightly soluble silver salt is formed to produce the solid substance. The antimicrobial agent is placed in a liquid or its flow channel and brought into contact with chlorine ion. Silver has high elution rate at an early stage but reduces it during the process of formation of the only slightly soluble silver salt. Silver is finally eluted in a fixed minimized elution rate to sterilize a liquid and its flow channel.

Title: Extruder for chopped face tile and manufacture thereof
Inventor: KATO SHOJI
IPC: B28B11/16
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing means capable of making thinner the thickness of a chopped face tile in which a two-split place forms a surface. SOLUTION: In the interior of an extruding die 3 of an extruder 1, a flow diverting member 10 is disposed at a position corresponding to a place where a base material of a tile is split in two, and a forward end 10a of the flow diverting member 10 is allowed to come closer to an opening face 3b of the extruding die 3. Further, a gap 4 extending along a direction in which body is extruded is formed between a side end 10b of the flow diverting member 10 and an inner wall face 3c of the extruding die 3. Since the base material of the tile extruded from the extruder 1 becomes weak in a bonding power of the body at a flow diversion portion which has allowed the flow diverting member 10 to pass therethrough, it can be split in two after burning. Accordingly, since a two-split process can be conducted for the base material of the tile having a great shock-resistant strength after burning, the thickness of the tile can be made thinner.
