IPC: G11B7/22
Filed: 1991-12-12
Abstract: PURPOSE:To miniaturize the device by providing an actuator for driving an objective lens part on a base body and providing a light emitting part with a pedestal part provided on the base body and a semiconductor laser chip. CONSTITUTION:The heat generated in the semiconductor laser chip 20 is transmitted through the semiconductor pedestal 24 and metallic pedestal 23 to a housing 15 and is radiated by the housing 15. Then, the housing 15 functions as a heat sink and, therefore, there is no need for separately providing a heat sink and the reduction of the thickness of the optical head is possible. The two-dimensional actuator 100 is constituted to drive only the objective lens 50 and can, therefore, execute tracking control and focus control with a small driving force. Since the semiconductor pedestal 24 is used as the pedestal in contact with the semiconductor laser chip 20, the semiconductor laser is kept free from the stress by a difference in the coefft. of thermal expansion.

IPC: E02D17/20
Filed: 1994-12-05
Abstract: PURPOSE: To improve the reliability on strength by coupling the head parts of a pile body buried in inclination to the side on which an earth pressure is exerted and a pile body buried in a ground inclining to the side opposite to the side on which the earth pressure is exerted. CONSTITUTION: A plurality of rear inclining piles 1b are buried in a ground inclining to the opposite side B to the side on which an earth pressure is exerted. The head parts of a plurality of piles 1a and 1b are integrally coupled by means of a coupling body 2. Bottoms 12 of front and rear inclination piles 1a and 1b are extended through a soft layer and penetrated to the given depth of a bearing layer. Whole head parts 11 of the front and rear inclining piles 1a and 1b are coupled integrally with a coupling body 2, such as a beam and a slab made of concrete in which reinforcing bars and reinforcing steels are buried, or a beam and a slab made of a steel. A compression force Nc is exerted on the front inclination pile 1a rather than a bending force and a pulling force Nt is exerted on the rear inclination pile 1b more mainly than a bending force.  However, the pile body has high resistance force thereagainst. The inclination pile 1a can resist against the compression force Nc by means of a peripheral surface friction force (t) and a pile bottom reaction force (q) and the inclination pile 1b can resist against a tensile force Nt by means of the peripheral surface friction force (t).
