Title: Multilayered printed wiring board
Inventor: ISHIGAMI FUMIO
IPC: H05K1/03
Filed: 1995-02-28
Abstract: PURPOSE: To prevent the occurrence of interfacial destruction at the boundary between an external-layer substrate and adhesive layer when a multilayered printed wiring board is subjected to a heat run after hygroscopic treatment by using glass cloth having air permeability smaller than a specific value as the base film of the external-layer substrate of the wiring board. CONSTITUTION: When a multilayered printed wiring board is subjected to a heat run after hygroscopic treatment, interfacial destruction is apt to occur at the boundary between an external-layer substrate and adhesive layer when the adhesive layer absorbs moisture. When the moisture absorption of the adhesive layer is suppressed, the heat resistance of the wiring board can be improved. The moisture adsorption of the adhesive layer can be suppressed when the hygroscopic property of an external-layer substrate is reduced. The simplest and most effective means for reducing the moisture permeability of the external- layer substrate is to reduce the air permeability of the glass cloth used as the base film of the substrate. When glass cloth having air permeability of <=5ml/cm<2> is used, the adhesive layer is hardly destroyed during a heat run after hygroscopic treatment.

Title: Slewing type operating device
Inventor: DOUKE NAOTAKA
IPC: E02F9/20
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To inhibit an impulse and a shaking return by controlling the quantity of the communication of a control valve opened at the time of slweing stop and used for a bypass on the basis of the attitude of an operating section. SOLUTION: When slewing is positioned at a neutral place from forward-turn side slewing, a reverse-turn side main oil path 17R reaches high pressure owing to the force of inertia, and pressure oil in the oil path 17R is flowed into a forward-turn side main oil path 17F through a brake circuit 23 when the main oil path 17R exceeds the relief pressure of the circuit 23, and an impulse and a shaking return are inhibited. Since relief pressure is set at high pressure for obtaining excellent slewing starting and stop performance at that time, the circuit 23 excellently functions under the state, in which the reach of an operating section is lengthened and the force of inertia at the time of slewing stop is increased.  The oil paths 17F, 17R are communicated through a bypass oil path 26 with a control valve 27 for a bypass under the state, in which the reach of the operating section is shortened and the force of inertia at the time of slewing stop is reduced, while the quantity of the oil path 26 communicated is controlled so as to be augmented in the shorter reach of the operating section. Accordingly, the slewing type operating device can be slewed and stopped smoothly regardless of the posture of the operating section.
