An optical apparatus is disclosed in which a press contact force for bringing a vibrator and a contact member into press contact with each other is generated between them, and thereby the reaction force of the press contact force is difficult to transmit outward. The optical apparatus comprises a lens holding member which holds a lens, and a vibration type linear actuator which drives the lens holding member in an optical axis direction. The vibration type linear actuator includes a vibrator on which vibration is produced through an electromechanical energy conversion action and a contact member which is in press contact with the vibrator. The vibrator and the contact member is in press contact with each other by a magnetic force acting between them.

A vaporizing device for chemical vapor deposition (CVD) source materials includes a vaporizer for vaporizing introduced CVD source materials by heating, a spray nozzle of which an end portion is fixedly attached to the vaporizer for spraying the CVD source materials into the vaporizer, a cooling mechanism for cooling the spray nozzle, and a heat conduction restrictor attached to the end portion, proximate of the end portion, or to the vaporizer. Generation of non-vaporized residues and particles is decreased, improving productivity owing to prolongation of continuous operation time of the apparatus and a decrease in film defects.

A thermoelectric piece has an increased adhesive strength between a semiconductor matrix of Bi--Sb--Te or Bi--Te--Se and a diffusion barrier layer deposited thereon for blocking diffusion of a soldering material into the semiconductor matrix. An Sn-alloy layer is provided between the semiconductor matrix and the diffusion barrier layer of Mo, W, Nb and Ni to give the enhanced adhesive strength. The Sn-alloy is formed at the interface with the semiconductor matrix by interdiffusion of Sn with at least one element of the semiconductor. It is found that Sn will not lower the thermoelectric characteristics when diffusing into the semiconductor matrix and provides an sufficient adhesive strength to the metal elements of the diffusion barrier layer. The thermoelectric piece is made through the steps of:a) preparing the thermoelectric semiconductor having opposed faces;b) depositing a tin layer on each of the opposed faces of the thermoelectric semiconductor;c) diffusing Sn mutually with at least one element of the thermoelectric semiconductor to form the Sn-alloy layer on the each of the opposed faces;d) depositing a diffusion barrier layer of Mo, W, Nb, or Ni on each of the Sn-alloy layer.
