Title: Magnetic disc device
Inventor: TAKAGI HITOSHI
IPC: G11B5/012
Filed: 1985-11-01
Abstract: PURPOSE:To decrease remarkably the crosstalk from an adjacent track by using two magnetic heads not in parallel with a prescribed tilt angle in common with each of adjacent tracks so as to generate an azimuth loss at the reproduction. CONSTITUTION:Magnetic heads 4a, 4b are fitted to a side face 21 of a twin-shell type slider rail, gaps 81, 82 have a prescribed tilt angle and are not in parallel with each other, a distance L between the core centers of each head is selected to an odd number multiple of a track pitch of a magnetic disc so as to use the heads 4a, 4b respectively corresponding to adjacent odd/even number tracks. In reproducing a signal recorded at one of the two magnetic heads not in parallel with a prescribed tilt angle theta by using the other head, an azimuth loss is produced, the loss is larger as the angle theta is larger and the recording density is higher. In the case of the reproduction with the head 4a which is not completely placed on a specified track but a part of which is placed on the adjacent track, since the adjacent track is recorded by the head 4b, a large azimuth loss is caused, its reproduced output is small and the crosstalk from the adjacent track is lowered.

IPC: H01L21/285
Filed: 1990-09-19
Abstract: PURPOSE:To augment the yield of wiring connection between a module and a wiring substrate by a method wherein the terminal on the element module to be connected to outer circuit is formed using the metallic film position process by the selective chemical vapor deposition(CVD) process. CONSTITUTION:A metallic film 6 is formed on the terminal connection part of a module using the selective CVD process to avoid the direct beam irradiation of a substrate so that the contact resistance may be lowered by interposing the selective CVD metallic film 6 between the substrate 1 and a maskless formed wiring 7. That is, the connection part connects the impurity doped layer 4 of a module substrate 2 arranged on the wiring substrate 1 with an insulating film 3 formed thereon to a substrate wiring 8 by a wiring 7 between module/ wiring substrate through the CVD tungsten film 6 selectively deposited in the connecting hole of a module insulating film 5.

IPC: G11B7/09
Filed: 1989-09-22
Abstract: PURPOSE:To realize smooth sliding and turning operation by driving a supporting shaft by plural solid actuators, and applying variable pre-load to a space between the supporting shaft and a bearing. CONSTITUTION:Since layer-built peizoelectric elements 20a, 20b, 20c for pre- loading are arranged between a fixed stand 16 and a focus controlling yoke 8 supporting the supporting shaft 4, the supporting shaft 4 is moved by impressing definite voltage to the piezoelectric elements 20a, 20b, 20c. At the time, since a movable part is supported by a damper 5, pre-loading force is changed according to the voltage to be applied to the piezoelectric elements 20a, 20b, 20c. By applying the pre-load in a direction intersecting the supporting shaft at right angles to the space between the supporting shaft and the bearing, the unnecessary operation of the movable part due to the sliding and turning operation for focus control and track control or disturbance can be regulated. Besides, since a contact sport between the supporting shaft and the bearing can be changed, the abrasion of lubricant for the supporting shaft can be dispersed, and their lives can be lengthened.

Title: Pattern extracting system
Inventor: KURINO KIYOMICHI
IPC: G06K9/34
Filed: 1984-11-22
Abstract: PURPOSE:To set an optional form and an optional size with a frame pattern by extracting a subject pattern after performing AND processing between a pattern to be recognized and written on a form containing a frame pattern and a binary mask frame pattern produced from a frame inner or outer contour pattern. CONSTITUTION:The patterns of frames, characters, symbols, etc. formed on the surface of a form 2 are formed into images at a photoreceptor 4. The photoreceptor 4 converts these patterns into electric signals successively, and a binary-coding circuit 5 converts these electric signals into binary signals '0' and '1' according to the prescribed threshold value and sends them to a memory circuit 6. Then the overall recognizing pattern of the form 2 is stored by the signals '0' and '1'. A segmenting part 7 separates a frame pattern from the overall recognizing pattern stored in the circuit 6. Then a character or symbol pattern is extracted and each character or symbol is sent to a recognizing circuit 8. The circuit 8 compares the received pattern with a standard pattern stored in a file device 9. The coincident standard pattern is sent to an upper device 10 of another central processor.

Title: Rivet contact
Inventor: IMAI MASAMITSU
IPC: H01H1/06
Filed: 1989-09-22
Abstract: PURPOSE:To enhance the contact reliability of a rivet contact by reducing the area of the contact touching face of a head portion, and forming a network of flat projecting portions on the contact touching face. CONSTITUTION:The area of the contact touching face of a head portion 6 is reduced and a network of flat projecting portions 7 are formed on the contact touching face; e.g. a network of numerous square projecting portions 7 of 0.1mm side by 0.1mm height are flatly formed on the small-area contact touching face of a disc portion 6a of 0.6mm outside diameter provided at the upper end of the stepped head portion 6. Foreign material adhering to a contact surface is thus put in and escaped through numerous linear channels formed between the network of flat projecting portions even with a wiping phenomenon and therefore imperfect contact would not occur, and in addition, midpoint contact is achieved during opening and closing of the contact so that contact reliability is enhanced.

Abstract: PURPOSE:To improve the rising characteristic of a luminous flux at the starting time of lighting by air-tightly an inner tube, wherein a phosphor is applied to a glass tube having specific thickness, and electrodes inside an outer tube made of glass so that a double-tube structure may be formed. CONSTITUTION:An inner tube 2, wherein a phosphor 3 is applied to the inside of a glass tube having thickness under 0.3mm, and electrodes 4 and 4' are air- tightly enclosed inside an outer tube 1 together with gas for discharge consisting of a mixed gas of krypton and argon, and mercury so as to form the subject fluorescent lamp. Then, the inner tube 2 is fixed to the outer tube 1 at several points on the circumference with inorganic adhesive materials 5 and 5'. The phosphor 3 does not lower its efficiency in the steady lighting state at a high temperature even when the temperature of the inner tube 2 rises to about 100 deg.C. Further, since thickness of the inner tube 2 is under 0.3mm, thermal capacity becomes small so as to be rapidly heated simultaneously with a start of lighting. Thereby, the rising characteristic of a luminous flux at the start of lighting can be improved.
