An electromechanical transducer of the Coriolis type which provides an output in response to the mass flow rate of a fluid flowing in a pipe. The transducer has a flow tube, curved symmetrically with respect to an axis of symmetry lying in a tube plane, for conducting the fluid. It also has a rigid support body for mounting the flow tube, with the flow tube being fixed to the rigid support body at both an inlet end and an outlet end. It further has an excitation system which in operation excites...

The ironing board comprises a perforated worktop (1) enclosed by a casing (2) with which it defines a chamber (3) associated to ventilation means for the steam ejected by an iron to pass therethrough. The ironing board further comprises adjustable support legs (8, 9), whose upper end portions are connected directly to the worktop (1). At least one (9) of these legs is adapted to pass in an air-tight manner through a longitudinal aperture (20) provided in the casing (2).

An injection locking type or MOPA type of laser device capable of always obtaining stable output energy and wavelength is provided. For this purpose, the laser device includes an oscillator (11A) for oscillating seed laser light (21A) with wavelength band-narrowed by a band-narrowing unit (30), an amplifier (11B) for amplifying the seed laser light and emitting the amplified laser light (21B), a wavelength monitor (34A) for detecting at least a wavelength characteristic of the seed laser light, ...

A type element, which is mounted for movement along a writing line and has a plurality of types arranged thereon, is rotated through a differential mechanism to position a selected type at the printing position. The differential mechanism includes a first gear connected to the type element through a rotatably supported shaft. A sector gear meshes with the first gear to rotate the first gear in one direction in accordance with inputs to an arm on which the sector gear is mounted. The arm is pivot...

A printing device for use in print type equipment is provided, having a shaft, a print type drum affixed to the shaft and an auxiliary type drum adjustably mounted on the shaft. The auxiliary drum is secured to the shaft in abutting relation to one end of the print drum when in its operating position. A plurality of type segments are carried by a like number of mounting apertures or slots in the periphery of the auxiliary drum and are slidably removable therefrom. The type segments are removable...

A reflection type scanner to transparence type scanner converter, comprising: (a) a casing, having a flat upper surface installed with a scanning window; (b) a light source, fixed to the casing; (c) a power supply, to provide electricity required by the light source; (d) a light transmitter layer affixed to the scanning window of the casing, the light transmitter layer being made of a superior light conducting material and capable of minimizing light scattering so as to evenly distribute the lig...

A vibration type actuator comprises a vibration member for generating vibration displacements in at least three different directions and a contact member in contact with the vibration member. In the actuator the vibration displacements in at least three different directions are excited in the vibration member to generate synthetic vibrations that cause relative movement between the vibration member and contact member in a desired direction.

The present invention relates to a vibration type actuator or a vibration type driving apparatus that includes a vibration member that generates therein respective vibration displacements in at least three different directions, and a plurality of contact members contacting the vibration member, wherein the respective vibration displacements in the three different directions generate a composite vibration that simultaneously moves selected contact members of the plurality of contact members relat...
