Abstract: PURPOSE:To obtain a conducting metal material suitable for lead frames, which is characterized by excellent mechanical strength and conductivity, high corrosion resistance and excellent blanking property, by providing annealed copper layers, which are deposited on the surfaces of a thin plate made of stainless steel by electric plating. CONSTITUTION:For a lead frame 1, a thin plate made of stainless steel is used as a substrate. For example, when the price is emphasized, a ferrite material is used. When magnetic effect on a semiconductor pellet is avoided, nonmagnetic austenite material is used. The material is not limited to the lead frame in applications. When the material is used for the lead frame, the quality and the thickness are selected in consideration of the conductivity and the like. The thin plate 2 made of the stainless steel has the thickness of, e.g., 0.08-0.6mm. Copper layers 3 and 3 having the thickness of about 3-20mum are formed on the upper and lower surfaces by electroplating and annealed. Thus the physical characteristics are made to be those of soft copper. The plane pattern of the lead frame is the same as that of the conventional lead frame. A required shape is formed by blanking.

Title: Polyethylene pipe coupling for supply water
Inventor: KITAGAWA MASAYOSHI
IPC: F16L47/02
Filed: 1991-06-17
Abstract: PURPOSE:To provide a pipe coupling made of polyethylene which especially has an aptitude as a line for supply water. CONSTITUTION:Carbon black is mixed in a polyethylene material having density higher than that of a low density polyethylene pipe 2 for water supply, a pipe coupling 1 around an inner peripheral surface 11 of which a heating wire 14 is wound is formed. This constitution causes a pipeline to be durable to a concentrated stress even when an external force is exerted on the pipeline since it is of high density and high strength. Since carbon black is mixed, weather resistance is high. Since density is high inspite of being a mixture, chlorine water resistance is not lowered. When the surface contacts with a pipe is heated, a face pressure is kept to form a tight weld part.

Title: Resin film cover body
Inventor: KAWAHARA YOSHI
IPC: A61J1/05
Filed: 1994-06-29
Abstract: PURPOSE:To visually identify a degree of thermal welding to ensure an airtightness and an easy to openability by a method wherein a color difference produced by softening and reducing in thickness a white layer film and a welding layer film at the time of thermal welding is made to correspond to a wall thickness reduction ratio of the resin layers depending on a heating value. CONSTITUTION:A resin film cover body is formed by successively laminating a substrate film 11, a printing layer 12, a white layer film 13, and a welding layer film 14. The laminated film cover body is put on an opening of a closure edge part 10 with the welding resin layer brought into contact with the closure edge part 10. The cover body is pressurized along the peripheral part of the closure opening by abutting a heating die on the substrate film 11, thereby being thermally welded to the closure edge part 10. At this time, the white layer film 13 and the welding layer film 14 are reduced in thickness to produce a color difference from an unsealed part having no change in thickness. In this case, since the wall thickness is reduced in accordance with a heating value of thermal welding, the color difference is proportional to the wall thickness reduction ratio of the white layer film 13. In this manner, a degree of thermal welding can be identified as a color difference visually or using an image sensor.

Title: Automatic cruise controller
Inventor: MATSUOKA KEIJI
IPC: B60W30/16
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To provide an automatic cruise controller preventing the behavior of a vehicle unintended by a driver so as not to make the driver feel uneasy. SOLUTION: In case target vehicle speed is set and a set acceleration switch for changing the target vehicle speed is operated (S210, $220), the target vehicle speed is changed according to operation of the set accelerator switch when a set action mode is not an inter-vehicle mode (that is, the set action mode is a constant speed mode) or inter-vehicle cruise is not performed since there is no preceding vehicle even in case of the inter-vehicle mode. In case the action mode is the inter-vehicle mode and inter-vehicle cruise is in execution, an alarm is actuated without changing the target vehicle speed (S230-S260). That is, the target vehicle speed is not changed during inter-vehicle cruise.  When control is switched from intervehicle cruise to constant speed cruise, a vehicle is not therefore accelerated exceeding the target vehicle speed set at the time of starting inter-vehicle cruise.

Title: Developing device
Inventor: OZASA TAKESHI
IPC: G03G15/08
Filed: 1991-06-18
Abstract: PURPOSE:To provide the developing device where scattering outside of toner can be prevented and miniaturization and reduction of cost can be attained as well. CONSTITUTION:The scattering of toner from the developing device is often caused between a cutting pole S2, restricting thickness of the layer of the toner on the periphery, going through a developing pole S1, feeding toner to the image carrier, and a carrying pole N1, mixing the toner on the periphery with the toner inside the developing device main body 2. So an attracting catching plate 10 is provided to catch the scattered toner on the developing device main body 2 side installed facing these parts of the developer carrier 3. Therfore, scattering of toner outside the developing device can be sufficiently prevented by this attracting catching plate 10. Furthermore, since only the installment of the suction catching plate 10 is necessary for prevention of the toner scattering, the device can be miniaturized and the cost can be lowered.
