Title: Manufacture of composite lead frame
Inventor: UEDA HIROTAKA
IPC: H05K3/40
Filed: 1994-12-06
Abstract: PURPOSE: To enable a circuit pattern and a number of inner leads to be boded together continuously with high positional accuracy by making the inner lead of a lead frame, applied with a heat-fusion bonding material, abut against the circuit pattern of a circuit board and by irradiating the abutted part with radiant heat to achieve boding. CONSTITUTION: An inner lead 5 of a lead frame 4 whose tip is applied beforehand with a heat-fusion bonding material 6 such as a soldering metal, a brazing material, a metalized paste, is brought into abutment against a circuit pattern 3 of a circuit board 1, and heat-rays emitted from a rod-shaped infrared-ray source 11 are focused on the abutted part by means of a curved reflecting mirror 12 and a lens 13 to fuse the heat-fusion bonding material 6 for bonding the inner lead 5 with the circuit pattern 3. Thus, high positional accuracy can be achieved, since an excessive external force does not act on the part to be bonded, and quick and continuous bonding can be achieved, since the radiant heat can be focused on the required location.

Title: Electric heater
Inventor: NAKAZAWA TOSHIICHI
IPC: F24C7/06
Filed: 1987-12-25
Abstract: PURPOSE:To improve convenience in use, facilitate cleaning of an electric heater and prevent discoloration of a top plate by a method wherein a cover is fixed to a part of a scroll type sheath heater, the sheath heater is mounted in a tapered recessed part, the sheath heater is rotatably arranged through a projection hole and then two steps are arranged at opposing sides of an upper surface of the top plate. CONSTITUTION:When cooked, dew overflown from a pan etc. is kept in a tapered concave part 12 of a top plate 11. In case that the heater is to be cleaned, a sheath heater 14 is rotated around a projection hole 13 under a sliding movement of the cover 16 fixed to the scroll type sheath heater 14 and an end surface of the projection hole 13 and then it is removed from the tapered recessed part 12. With this arrangement, since the overflown dew can easily be removed and the two steps 11a arranged at opposing sides of an upper surface of the top plate 11 are placed at opposing positions with the sheath heater 14 being held in it, air flowed from one stepped part 11a passes below the sheath heater 14 and then passes through an other step 11a. As a result, the top plate 11 and the tapered recessed part 12 are cooled and their temperatures are prevented from being increased, resulting in that a discoloration caused by the temper color can be prevented.

Title: Ink jet recording head
Inventor: KODA HIROKAZU
IPC: B41J2/045
Filed: 1990-11-28
Abstract: PURPOSE:To enable an ink particle of an always uniform optimum shape and size to be effectively discharged by a method wherein a piezoelectric actuator constructed as to be deformed according to voltage to be applied is provided and for a wall member, an end part on a nozzle side is fixed and an end part on an opposed side of the nozzle is free. CONSTITUTION:Since piezoelectric actuators 21, 22 are deformed like dashed lines 21a, 22a to vary directly a volume of an ink chamber 20 when voltage is applied from a signal source 31, ink is discharged from a nozzle 27 to perform printing. Then, since an end part on the nozzle 27 side of a wall member enclosing laterally the ink chamber 20 is fixed to fixing members 32, 33 and an end part on an opposed side of the nozzle 27 is free, a part restricting motion of the piezoelectric actuators 21, 22 is little and the wall member of each ink chamber is individual by separation. Therefore, its deformation is easy and its driving efficiency becomes high. Further, since the piezoelectric actuator part is separated from said part of another ink chamber, it is difficult to be influenced by drive of the other ink chamber. Furthermore, since no pressure chamber which is, in a closed manner, constructed, exists, an air bubble entered the ink chamber 20 can be easily removed.
