Abstract: PURPOSE:To improve magnetic characteristic while effectively utilizing a mate rial by improving distribution of film thickness and composition. CONSTITUTION:A plurality of amorphous films 13 formed on a nonmagnetic substrate 11 in such a condition that atomic layers of rare earth RE and transistor metal TM are alternated within the same layer are working as a recording layer. The amorphous film 13 is stacked between an under layer 12 and a protection film 14 formed on the substrate and the protection film 14 is further provided with a formed reflection film 15 and moreover a protection film (UV) 16. RE and TM layers are simultaneously formed using a couple of corresponding target substances by the sputtering method while the substrate 1 1 is rotated. Therefore, two layers are formed to satisfy the relationship that a thickness ratio TM/RE of the rare earth RE and transition metal TR in one unit at the lattice surface interval L of each atomic layer stacked during rotation of the substrate 11 is larger than 1.2 but is smaller than 1.8 (1.2<(TM/RE)<1.8).

Filed: 1990-05-31
Abstract: PURPOSE: To easily secure an adhesive tape to a roll by forming an intermediate section between a first section and a second section of a slip, providing first and second adhesives inside the first and second sections instead of providing an adhesive inside the intermediate section, and providing the tape with first to fourth mutually parallel cut lines, located in the sections of the slip without arriving to the first adhesive. CONSTITUTION: An adhesive tape 10 is secured to a roll 12 in place by thrusting a first section 41 of a slip 40 against an outside layer 11 and thrusting a second section 42 of the slip against an inside layer 14. In this case, all four bands A, B, C and D protect the outside layer of a pressure sensitive adhesive 44 against dirt. Before the roll 12 is transferred to an adhesion station, the bands A, B are separated from the adhesive 44. In this way, two pressure sensitive adhesive stripes 56, 57 in the longitudinal direction are exposed to the outside of the tape 10 and these stripes 56, 57 are used for continuous adhesion. The band B, not separated, is functioned as a protecting bridge between these stripes 56, 57.

IPC: B23K15/00
Filed: 1985-06-29
Abstract: PURPOSE:To perform a good welding without any defect for a thick plate as well by providing a specified gap on the groove and by welding the strip plate of the specified thickness and width inside the gap with its feeding from the upper to the lower in case of the electron beam welding in vertical upward position. CONSTITUTION:The welding is performed by providing the gap of about 1-3mm on the groove of a welding joint 2 with feeding from the opposite direction (from up to down) to the welding progressing direction the strip plate having 0.5-2mm thickness and its width being the same or slightly smaller thickness than that of the welding joint inside the gap. For instance the electron beam welding is started by a starting piece 1 first. The grooves of both sides are welded by increasing slightly more than the gap the amplitude at right angle with the welding direction of the electron beam 8. A strip like wire 7 is then fed by a feeding roller 6 to adjust the feeding quantity thereof. The welding is completed by an ending piece 3 by moving the position of the electron beam 8 in the direction of the welding joint 2 in this state. Due to the droplet of the molten metal being prevented by the feeding of the wire 7 the vertical welding of high quality can be performed.

IPC: G05F1/10
Filed: 1988-06-10
Abstract: PURPOSE: To obtain a starting circuit for a power supply device small in volume and small in occupying area by using a comparator and a single capacitor. CONSTITUTION: Trickle DC voltage supplied to a line 32 trickle-charges a capacitor 44 through a resistor 42 until the voltage impressed to both the ends of the capacitor 44 reaches a reference signal voltage on a line 46. When the voltage on both the ends of the capacity 44 becomes equal to the reference signal voltage on the line 46, a switch 50 is closed by a comparator 48, and the capacitor 44 supplies its stored electrostatic charge to a controlling logic device through the line 34. Thus the dimension and volume of the starting circuit are physically small and only a small area is occupied by the circuit.

Title: Electronic still camera
Inventor: OGURA SHIGEO
IPC: G03B13/02
Filed: 1989-06-08
Abstract: PURPOSE:To attain optimum diaphragm control for each application by controlling diaphragm speed in the use of an electronic view finder and an diaphragm speed at image pickup different from each other in an electronic still camera having the electronic view finder. CONSTITUTION:When a release switch SW 1 is set, the diaphragm, the shutter speed are decided by an output of a photometry sensor. The diaphragm is set at a slow speed V1 for the electronic view finder(EVF), the storage time is changed by an electronic shutter and a video image is outputted on the EVF for each vertical transfer pulse. When the SW 2 is closed, the diaphragm 21 and the shutter speed are calculated again at this point of time, the diaphragm speed is changed from the V1 into the V2. Thus, the diaphragm tracking performance with respect to a rapid change in the brightness for a short time of an object slows down to some degree in the use of EVF. As a result, the flicker of the pattern is prevented and the release time lag at image pickup is decreased.
