IPC: H01L23/32
Filed: 1978-12-27
Abstract: PURPOSE: To package an element directly on a substrate and thus to save an operation process and production cost by a method wherein one end of conductor wiring is projected on a through hole or a hollow provided in the substrate, and an electrode of the semiconductor element is connected to the conductor wiring.  
     CONSTITUTION: On one surface of a printed substrate 1 provided with a given through hole 2 or hollow, one end of a conductor wiring 3 is allowed to project on the through hole or the hollow and bent at its free end, and where necessary, an insulator solder flow preventing material 4 which is not so big to cover the free end entirely is further formed. Next, a semiconductor chip 5 provided with a solder bump 6 is soldered and connected to the free end 7 at a portion where the solder flow preventing material 4 is not formed. According to this method, a stress according to a difference in the coefficient of thermal expansion arising after chip bonding between the substrate 1 and the chip 5 is absorbed at the free end, and thus the stress working on the connection is reduced. Not only solder but also conductive metal is preferable for electrode on the chip.

Filed: 1982-09-14
Abstract: PURPOSE:To improve the sensitivity, accuracy and reproducibility in quantitative determination in a method of determining human grown hormone (HGH) by a radioimmunoassay method by binding HGH to an immobilized carrier then bringing the bound matter, the HGH which is an object to be determined and radioactive label HGH into reaction. CONSTITUTION:The spleen is drawn from a mouse injected with HGH and is prepd. into a single cell suspension, whereafter the suspension is united by mouse myeloma cell and polyethylene glycol. The united cell are screened by an HAT selective medium and further the anti-HGH antibody produced clone is selected and is cultured in vivo, then a monoclonal anti-HGH antibody is drawn. The anti-HGH antibody is incubated and immobilized to an immobilizing carrier, to which an object to be determined, i.e., HGH and radioactive label HGH are added. Part of the radioactive label HGH is bound by competitive reaction with the anti-HGH antibody immobilized to the immobilizing carrier. The HGH in the sample is determined by counting after washing. Since the radioactive label HGH bound with the anti-HGH antibody is thoroughly separated, the sensitivity, accuracy and reproducibility of quantative determination are considerably improved.

IPC: H01J31/15
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a simple grid at low cost without performing etching by providing a metal mesh stuck to a metal frame body formed from metal wires and formed by braiding the metal wires. SOLUTION: A metal frame body 20a is mounted on one face of a metal mesh 23 and they are crimped by applying pressure from the upper and lower sides of the metal frame body 20a and the metal mesh 23 (cold welding). That is, this process utilizes an anchor effect caused by applying high pressure to the metal and dispenses with any adhesive or electrical welding, so that a manufacturing process becomes very simple. Unwanted metal mesh 23 hanging out from the metal frame body 20a is cut off. A grid 6 is finally provided by bending a part to become a leg, when it is mounted on a glass substrate. For instance, stainless steel having a diameter of 10-300 μm is used for the metal wire 20 and one having 30-150 μm square-shaped stitches is used for the metal mesh 23. Because an etching process is not performed, the disposal of waste liquid is not required.

Title: Write compensation circuit
Inventor: YANAKA TAKESHI
IPC: G11B20/10
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a constant synthetic resistance value not being based on temperature change and to obtain output from a stable integration circuit, by providing a temperature detecting device adjacently to an encoder circuit, and integration circuit, and an OR circuit. CONSTITUTION:When a temperature in the neighborhood of the encoder circuit 1, the integration circuit 2, and the OR circuit 3 changes, the resistance value of a thermistor S1 changes. The resistance value of the thermistor S1 is decreased when the temperature rises, and is increased when it falls. Meanwhile, the resistance values of resistors R1-R3 are increased when the temperature rises and are decreased when it falls. Therefore, it is possible to keep the synthetic resistance value of the resistors R1-R3 and the thermistor S1 constant for the temperature change by inserting the thermistor S1 between the encoder circuit 1 and the integration circuit 2. In such a way, stable output can be obtained in the integration circuit 2.

Abstract: PURPOSE:To reduce the number of parts and to reduce cost in a lens barrel provided with a photointerrupter by interposing the photointerrupter between the lens barrels and forming an elastic part pressing the photointerrupter to either lens barrel in the other lens barrel. CONSTITUTION:This lens barrel is constituted by interposing the photointerrupter 10 between the lens barrels 5 and 7 and forming the elastic part 5C pressing the photointerrupter 10 to either lens barrel 7 in the other lens barrel 5. In the case of assembling the lens barrel, the photointerrupter 10 is dropped in the groove parts 7a and 7b of an afocal ring 7 being either lens barrel. Then, in the case of assembling the afocal ring 7 in the fixed lens barrel 5 being the other lens barrel, the photointerrupter 10 is pressed (negative pressure) and held on the wall surface of the groove parts 7a and 7b by the elastic part 5C formed in the lens barrel 5. Thus, a printed circuit board or the backing material of a main flexible lead wire for fixing the photointerrupter 10 and a screw and a positioning pin for fixing the printed circuit board or the like are not required, so that the degree of freedom in design is increased.

Title: Magnetic recording medium
Inventor: OGASA KAZUO
IPC: G11B5/70
Filed: 1977-12-28
Abstract: PURPOSE: To eliminate the disadventage that the repetitive times until output decreases owing to clashing in contact/start-stop becomes small by containing flourine resin powder in the hard magnetic disc recording medium.  
     CONSTITUTION: Magnetic powder, fluorine resin of 0.5 to 20wt% thereof and thermosetting resin are kneaded in an alumina bowl together with a suitable solvent and the fluorine resin is ground preferably down to particle size 0.5 μ . Such magnetic coating is spin-coated on an Al substrate and is baked at 200 to 250°C. As a result, the magnetic disc recording medium is superior in abrasion resistance and impact resistance, due to which the wear-down of the film thickess during use is less. Damages to be given to head core after repetition of contact/start-stop are also slight.
