Title: Optical reproducing device
Inventor: TSUCHIYA YOICHI
IPC: G11B7/1275
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To preform the recording/reproducing of disks whose thicknesses are different like disks of a standard thickness type (CD, HDCD) and a thin thickness type (SD). SOLUTION: This reproducing device irradiates a laser beam on signal recording surfaces 51a, 52a of optical disks 51, 52 via an objective lens 24 and also reproduces a signal by guiding the laser beam to be reflected on the signal recording surfaces 51a, 52a to a photodetector 40. At this time, the effective numerical aperture is controlled by throttling the effective numerical aperture of the objective lens 24 in accordance with the ticknesses of substrates by a polarizing filter 31 so that a laser spot is made to be focused on the signal recording surface of the optical disk or by changing over the laser spot so as to be transmitted without throttling the spot by the polarizing filter 31 with respect to plural kinds of the optical disks whose thicknesses of substrates are different.  Moreover, focal distances are changed in the inner peripheral part and the outer peripheral part of the objective lens 24.

Filed: 1983-07-15
Abstract: PURPOSE:To obtain a wiring, dimensional accuracy thereof is high and resistance thereof is low, by forming the wiring on a package substrate by multilayer wiring consisting of titanium and copper. CONSTITUTION:A wiring 4 is formed as three layer thin-film multilayer wirings consisting of a titanium layer 10 formed on a package substrate 11 after sinterings through the evaporation of a thin-film, a copper layer 11 evaporated on the layer 10 in a thin-film shape and a titanium layer 12 evaporated on the layer 11 in the thin-film shape. A pedestal section 5 is composed of a copper layer 13 evaporated on the titanium layer 12 as the uppermost layer of the wiring 4 in the thin-film shape and a titanium layer 14 evaporated around the copper layer 13 in the thin-film shape. Since the wiring 4 is formed by the three layer thin- film evaporated layers of the titanium layer 10, the copper layer 11 and the titanium layer 12, the wiring 4 and the pedestal section 5 are formed with dimensional accuracy higher than a tungsten wiring formed through sintering. Accordingly, a large-sized pellet can be face-down bonded. The resistance of the wiring 4 can be lowered by the presence of the copper layer 11.

Filed: 1981-08-17
Abstract: PURPOSE:To produce the titled substance useful as a paper additive, by reacting an acrylamide polymer with a hypochlorite in an alkaline range and adding a water-soluble amine/epichlohydrin polycondensate in the course of the reaction. CONSTITUTION:An aqueous solution of sodium hypochlorite and caustic soda is added with stirring to an aqueous solution of an acrylamide polymer and reacted at about -5-40 deg.C (so-called Hofmann reaction). Then, before the chlorine in the reaction system decreases to 1mol%, based on the carbamoyl groups of the  acrylamide polymer, at least about 1wt%, based on the crylamide polymer, amine/epichlorohydrin resin is added to effect a reaction. After the reaction  system has attained a desired viscosity, a reducing agent such as sodium sulfite  is added to stop the crosslinking reaction. The aqueous cationic polymer solution  obtained can be stably stored by adjusting its pH to about 3.5-5.5.

Abstract: PURPOSE:To prevent the slip to be caused between the strip and the roll on purpose to prevent the generation of scratch flaws in the surface of the strip and the roll, by rotating due to the tension of the strip the hollow roll being rotatably fitted to outside of the roll shaft unrotatable by the tension of the strip, and is being suspended by the hydrostatic fluid pressure. CONSTITUTION:On both outsides of the cylindrical shaft 2 like as the deflector roll, etc., being unrotatable by the tension of the strip, the pockets 3, 4, extending along the longitudinal direction are installed on the opposite side. Within the shaft 2, the passages 5, 6, for passing the pressure fluid are installed, and are communicated to both pockets 3, 4, through the communicating passages 7, 8. The hollow roll 1 possessing inner diameter slightly larger than the outer diameter of above shaft 2 is freely rotatably fitted to outside of the shaft 2, and is suspended by the hydrostatic pressure of the pressure fluid being held in the pockets 3, 4. The strip S is laid on the surface of the hollow roll 1, and is moved forward; hereupon, the shaft 2 does not rotate, and only the hollow roll 1 rotates around the shaft 2, being suspended by the hydrostatic pressure; hereby, any slip is not caused between the strip S and the roll 1, so that any flaw is not generated in surface of the strip S and the roll 1.

Title: High-precision grinding method for semiconductor wafer
Inventor: ABE KOZO
IPC: B24B7/04
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To provide high flatness. SOLUTION: In a high-precision grinding method for semiconductor wafers 3, with which the semiconductor wafer 3 is ground by a cuptype grinding wheel 5, the semiconductor wafer is ground in state where the outer periphery 7 of a layer 6 of abrasive grains of the grinding wheel 5 coincides with the center 0 of rotation of the semiconductor wafer 3. Since the center part of the semiconductor wafer 3 is maintained at about the same temperature as those of the peripheral part, thermal expansion of the center part of the semiconductor wafer 3 is suppressed, and thus the flatness of the wafer after grinding is improved.

Title: Brake holding valve
Inventor: KUBOTA HITOSHI
IPC: B60T11/28
Filed: 1984-06-21
Abstract: PURPOSE:To make a brake holding valve so as to normally function all the time, by installing a spring rigging which comes into contact with a valve member before it touches an iron core when this valve member is attracted by an electromagnet unit. CONSTITUTION:When a coil 59 is energized with a continuous rating current, a valve element 31 is attracted to the side of an iron core 34, that is, moves to the side of the iron core 34 while compressing a spring 30 rolled on the circumference of a projection part 40a of a valve insertion plate 40, and it comes into contact with the iron core 34. Therefore, in a state that it touches the iron core 34, it receives sufficient large restoring force of a spring 90 and attracted to the iron core 34 to the full. When the coil 59 is unenergized out of the current, even if residual magnetism remains in the iron core 34 or the valve element 31, such a state of things that the valve element 31 and the iron core 34 are left attracted intact and the valve element 31 fails to move is avoidable without fail.

Abstract: PROBLEM TO BE SOLVED: To make possible a welding operation using a single device even when plural synthetic resin members with varying terminal size or shape are electrically welded by providing a part for connecting to plural terminals with varying size or shape on a connector. SOLUTION: A connector 4a has holes 42, 43, 44, for connecting a terminal, which have three different sizes respectively on the end face of a connector main body 41 of a synthetic resin. The holes 42, 43 for connecting to a terminal are of the almost T shape in cross section respectively, and conductors 42a, 43a consisting of the holes 42, 43 perforated in the vertical piece of the T shape are embedded in the connector main body 41. Further, the conductors 42a, 43a are electrically connected to cable 28a provided in the connector main body 41 through a conductor plate 46 to which one of the ends of the cable 28a is connected. On the other hand, the hole 44 for connecting a terminal is formed by insetting a synthetic resin member 44a with the hole 44 formed into the connector main body 41.  Thus it is possible to electrically weld various types of joint using a single electrowelding device as the connector 4a has holes 42, 43, 44 for connecting terminals with three different diameters.
