Title: Sealing method for package
Inventor: MATSUDA OSAMU
IPC: H01L23/02
Filed: 1987-05-11
Abstract: PURPOSE:To perform the processing of sealing a package with good controllability and productivity by forming high thermal absorptivity shape or layer of thermoplastic resin on at least one of package sealing sections, heating it by radiating means to melt the sealing section and sealing the package. CONSTITUTION:A semiconductor element 3 is previously secured to a header 1 to be connected to an electrode 4 formed of a lead frame, a cap 2 is covered and sealed. The sectional shape of the bump 2a of the cap 2 is preferably formed in a sharp state to have good thermal absorptivity, i.e., to be easily melted when it is heated, but may be of other shape, such as a dome state. In case of sealing it, the bump 2a of the cap is brought into contact with the sealing part la of the header 1, suitably pressed, and, if the cap 2 is transparent, a laser light is, for example, transmitted from a direction A to irradiate the bump 2a. Then, since the bump 2a has a small shape and a low thermal capacity, it is easily melted by the heat of the laser. When it is melted, it is fusion- bonded to the sealing part of the header 1. Thus, the sealing step is simplified to improve productivity.

Title: Electrostatic capacity type video disc reproducing stylus
Inventor: SEGAWA KEISHI
IPC: G11B9/07
Filed: 1978-09-18
Abstract: PURPOSE:To improve reliability to damage of a reproducing stylus as well as mass- producibility by bonding an electrode, which detects an information signal, to a flank surface formed by elongation in the same direction as the tangent of a track of the reproducing stylus. CONSTITUTION:Since constant-width streak part 23b of electrode 23 is formed on surface 22 in parallel to the scanning direction of reproducing stylus body 21, shock due to the elastic restoration of video disc 2 never operates upon end part 23a under the electrode and no thermal energy attending upon a scan converges. Further, since the electrode is applied with Hf or Ti by sputtering, its thickness is thin and precisely set, so that a video disc of extremely-high density can be obtained. Further, there is no need to symmetrize reproducing stylus body 21 on the scanning direction, and consequently the number of polished surfaces is reduced, providing excellent mass-producibility. In this way, reliability to a breakdown and mass- producibility will both improve.

Title: Magnetism sensing element
Inventor: SHINOHARA HISAJI
IPC: G01D5/20
Filed: 1988-05-11
Abstract: PURPOSE:To maintain high sensitivity and to provide polarity deciding ability for an excessive magnetic field by using a wire made of amorphous magnetic alloy with high magnetic permeability for a magnetic core, providing the magnetic core with winding, and storing them in a container made of a soft magnetic material. CONSTITUTION:The wire 4 of amorphous magnetic alloy is used as the magnetic core, which is provided with the winding 5; and the wire 4 of amorphous magnetic alloy and the winding 5 are put in the container 6 made of the soft magnetic material. Then when the magnetism sensing element is arranged in a magnetic drum which is long in magnetic pole length, i.e. large in magnetic field intensity, the majority of lines of magnetic forces from an N pole reach an S pole through the container 6, so a magnetic field operating on the magnetism sensing element is weakened properly to prevent th4e element from being saturated magnetically. Further, when the magnetism sensing element is arranged in a magnetic drum which is short in magnetic pole length, i.e. small in magnetic field intensity, the by-pass effect of the container 6 operates on a magnetic pole distant from a magnetic pole to be detected by the element, and the magnetic field which operates on the element is not weakened.
