Title: Semiconductor device
Inventor: SHIMAO TOSHIHIKO
IPC: H01L23/50
Filed: 1991-12-24
Abstract: PURPOSE:To prevent nonconformity due to stress which occurs when a lead frame is cut by forming claws, for preventing the lead frame from being withdrawn from a molding resin, on the lead frame inside a mold. CONSTITUTION:Claws 11 standing on a part of a lead frame 2 are provided, which in turn causes a contact area between the lead frame 2 and resin 1 to be increased. This results in a structure which resists against the withdrawal of the lead frame 2 when the lead frame is cut. Depending on the shape of a lead frame to be molded, a similar result will be yielded by forming claws on either the upper and lower or the right and left sides of a lead frame. Thus, nonconformity due to stress which occurs when a lead frame is cut is decreased, and highly reliable products are manufactured by forming claws on a part of a lead frame so that the fusion bonding property between a molding resin and a lead frame can be improved.

Title: Blank material for flute
Inventor: KONO KIICHI
IPC: C22C5/04
Filed: 1991-12-25
Abstract: PURPOSE:To obtain the blank material for a flute having excellent mechanical characteristics and working characteristics, excellent gloss and high-grade feel without having flaws in appearance by constituting the material of 1 to 15% Pd, 1 to 15% Co and the balance Pt. CONSTITUTION:This blank material consists of 1 to 15% Pd, 1 to 15% Co and the balance Pt. Namely, the Pd is incorporated at 1 to 15% therein and, therefore, the mechanical characteristics and the plastic workability are improved. Since the Co is incorporated at 1 to 15% therein, castability (prevention of generation of pinholes) and the mechanical characteristics are improved. The machinability is improved and the easy polishing and lustering are assured by forming the blank material of the PtPdCo alloy. These characteristics are thus well exhibited in size, shape, appearance, function, etc., in working as the flute. The effect of improving the mechanical characteristics is low if the content of the Pd is below 1%. The corrosion resistance is poor if the content of the Pd exceeds 15%. The effect of improving the castability and mechanical characteristics is low if the content of the Co is below 1%. The workability is drastically degraded if the content of the Co exceeds 15%.

Patent JP-H05182746-A (JP)
Title: Heater
Inventor: OTA SHIGEO
IPC: G03G15/20
Filed: 1991-12-28
Abstract: PURPOSE:To prevent deterioration with the lapse of time of a border between a heating body and a conductor electrode without deteriorating the temperature property of the heating unit by making the form of the edge of the conductor electrode superposing on the belt-form heating body to make the extending length longer than the width of the belt-form heating body. CONSTITUTION:A conductor electrode 3 is formed to make the edge 3a superposing on a heating body 2 cross obliquely to the heating body 2. As a result, the extending length of the edge 3a of the electrode 3 crossing obliquely to the heating body 2 in such a way is made longer than the width size of the heating body 2. Furthermore, since the edge 3a of the electrode 3 crosses obliquely to the heating body 2, the border (the edge 3a) between the electrode 3 and the heating body 2 is existing along a specific range in the longitudinal direction of the heating body 2. As a result, the temperature inclination from the high temperature heating part A in the heating body 2 to the low temperature part C in the electrode 3 is relaxed by a border B in a specific length range in the longitudinal direction of the heating body 2. Consequently, a thermal stress generated between the heating body 2 and the electrode 3 is also relaxed.
