Title: Resin laminate on metal
Inventor: KOJIMA YOSHIHARU
IPC: B32B27/42
Filed: 1990-08-28
Abstract: PURPOSE:To provide a laminate having high strength and excellent in water resistance, heat resistance and chemical resistance by providing a resole type phenol resin layer and a layer of a hydrogenated polybutadiene having a carboxyl group at the single terminal of its molecular chain on the surface of a metal and providing a polyolefin layer thereon. CONSTITUTION:A phenol resin is applied to the surface of a metal. As the phenol resin, a resole type phenol resin oligomer is used and hydrogenated polybutadiene (CHP) having a carboxyl group at the single terminal of its molecular chain is added to the phenol resin within the range of 0.1-10 pts.wt. per 1 pts.wt. of the phenol resin. The coated CHP-containing phenol resin is dried in air or dried by a blower or vacuum drying to volatilize the greater part of the solvent in the resin and subsequently heated to be cured. In this case, the resin is heated at 150-250 deg.C for about 5-120min. By this heating, the phenole resin completes a three-dimensional reticulated structure but a polyolefin is applied to the phenol resin layer as an overcoat layer before completion.

Title: Magneto-optical recording method for magneto-optical disk of large heat time constant, recording device and magnet0-optical disk
Inventor: SAITO JUN
IPC: G11B11/10
Filed: 1992-08-26
Abstract: PURPOSE:To exactly record in a disk of large heat time constant by a mark length recording system by adjusting a timing emitting and quenching laser beam by depending on the pattern of a data signal. CONSTITUTION:In the case of a light emitting timing, the shorter/the longer the previous quenching light time is, the light emitting timing is delayed/ quickened. In the case of a light quenching timing, the longer/shorter the previous quenching time, the light quenching timing is quickened/delayed. Thus, in a magneto-optical disk which has large data pattern dependency for forming a mark and more than 30nsec of heat time constant, the timing emitting/ quenching laser beam is adjusted by depending on the signal pattern of data. Thus, the edge shift amount of the mark becomes constant regardless of patterns, a recording can be exactly performed in the disk of large heat time constant by the mark length recording system and the window margin at the time of reproduction becomes wide.

Abstract: PROBLEM TO BE SOLVED: To raise cost-benefit and also to reduce variation tolerance by between a measurement terminal and an antenna attaching part, directly forming an inductive block in series with a transmission line and a capacitive block in parallel to the transmission line with pattern and through-hole in this order. SOLUTION: With the state where matching is established on the wireless circuit side B when a connector terminal of a measurement device is connected to a measurement terminal 1, the connector terminal is removed from the measurement terminal 1, so that conformity on the wireless circuit side B is likewise when viewed from an antenna attaching part (a). Thus, in both the state where the connector is connected to the measurement terminal 1 and the state where the antenna is attached to the antenna attaching part (a), matching on the wireless circuit side B is similar, so that the operation on the wireless circuit side B does not change. Since, a conductive component (b) and a capacity component (c) for a stub are directly formed with a printed board itself, cost merit is raised and variation tolerance is reduced.
