Title: Solder fusion-connecting method
Inventor: KUSANO MASAAKI
IPC: H05K3/34
Filed: 1979-03-16
Abstract: PURPOSE: To achieve the elimination of need for pre-soldering work on a wiring substrate by aligning the solder alloy electrodes of a circuit element on the specific metal layer provided on the wiring conductor surface of the wiring substrate and heating the same to fuse.  
     CONSTITUTION: In the case of fusion-connecting the solder alloy electrodes 2 of a circuit element 1 to the wiring conductors 4 of a wiring substrate 3, hitherto the connecting portions 5 of the conductors segmented by an insulation layer 6 are coated thereon with flux and are then dipped in a solder tank, by which they are subjected pre-soldering, but since the connecting portions are fine, the wetting of the alloy is poor. Thereupon, the plating layer composed of the metal of the single composition which is well wetted by alloys of gole, copper, tin, etc. is beforehand formed on the connecting portions and the solder alloy electrodes are contacted onto this plating layer, thence they are directly heated to fuse, whereby the circuit element may be connected readily and surely.

Title: Information recording method of floppy disk
Inventor: ITOU KATSUHIKO
IPC: G11B5/016
Filed: 1982-02-26
Abstract: PURPOSE:To increase the amount of information which can be recorded without causing any off-track phenomenon by making track density greater at an outer circumference where expansion depending upon temperature and humidity is large than at an inner circumference where the influence of the expansion is less. CONSTITUTION:In an area (a) from an outermost circumferential track (0 track) to the 1st track, recording with the conventional standard track density of 48 TPI is performed. In an area (b) from the (i+1)th track on the inner circumferential side to an innermost circumferential track, the track density is doubled to 99 TPI. A switching track (i) depends upon the expansion/contraction length of a medium, but when this track (i) is nearly a half the overall length, the storage capacity of each side of floppy disk is increased by one and half.

Abstract: PURPOSE:To permit continuous and exact measurement by providing means which can move a cylindrical body having a measuring electrode to the inside and outside of a particulate matter passage and oscillates the cylindrical body. CONSTITUTION:The moisture of the particulate matter (e.g., sand) in a housing 12 made of a stainless steel of a sensor body 2 is measured by measuring the electrostatic capacity between the housing 12 and the electrode 11 provided via an insulator 60 to the housing 12. The sensor 2 is moved together with an oscillating vessel 4 covering the base 2b of the sensor 2 by shafts 10, 20 of hydraulic cylinders 15, 20 (not shown) to the sand falling passage on the right side of the figure so that the sand is packed into the vessel. Both the sensor 2 and the vessel 4 are taken out of the sand passage and an oscillator 6 is actuated to compress the sand in the sensor 2. Then, the specified density is attained and, therefore, the exact measurement of the moisture is permitted. The vessel 4 is moved toward the left side of the figure after the measurement. The base 2b of the sensor 2 is then opened and the sand in the sensor 2 is dropped and removed. Since the sensor 2 can be moved into and out of the sand passage, the continuous measurement is permitted.

Abstract: PROBLEM TO BE SOLVED: To improve the connection reliability between thin-film multilayer wiring layers by securing adhesion strength between a pattern part with a weak adhesion force between a pattern on a substrate and an upper-layer film and the upper-layer film. SOLUTION: Chromium/silicon alloy layer 10 for forming a resistance element and a photo-sensitive polyimide layer 11 for forming a second insulation layer of an upper layer have weak adhesion force and aluminum chelate film 12 is formed as a connection layer between the layers. However, when the aluminum chelate film is formed on an entire surface, a photo-sensitive polyimide layer 11 of the second insulation layer and polyimide layer 9 of a first insulation layer become weak. Therefore, aluminum chelate film 12 is formed as a connection layer only at an interlayer between the chrome/silicon alloy layer 10 for forming the resistance element and the photo-sensitive polyimide layer 11 for forming the second insulation layer.
