A projector includes a main body and a projection lens. The main body includes a light source, liquid crystal panels that modulate light outputted from the light source, and a lens holder to and from which the projection lens is attachable and detachable. The projection lens projects the light modulated, and the lens holder includes a first lens holding mechanism and a second lens holding mechanism that hold the projection lens.

Projection-type display apparatus and lens holding mechanism

A projector includes: an exterior case having plurality of penetration holes; first base member fixed inside the exterior case and made of metal or crystalline resin; illumination unit fixed to first base member; image forming unit fixed to first base member; optical projection unit coupled to image forming unit; and second base member fixed inside exterior case and coupled to first base member, and having lower rigidity than first base member. First base member has plurality of first fixing parts which are arranged corresponding to position of part of plurality of penetration holes in exterior case and to which suspension fitting is fixed. Second base member has second fixing part which is arranged corresponding to position of penetration hole other than penetration holes having plurality of first fixing parts arranged therein, of plurality of penetration holes in exterior case, and to which suspension fitting is fixed.

A film forming device includes: a first discharge unit for discharging a first liquid material, in which a film forming material is dissolved in a solvent or dispersed in a dispersion medium; a second discharge unit for discharging a second liquid material containing a liquid with the same component as the solvent or the dispersion medium; and a removal unit for removing the solvent or the dispersion medium from droplets of the first liquid material arranged on a substrate by the first discharge unit, while removing the liquid, arranged on the substrate by the second discharge unit, from droplets of the second liquid material; wherein a film is formed on the substrate, by arranging the droplets of the first liquid material on first parts on the substrate by the first discharge unit, while arranging the droplets of the second liquid material on second parts on the substrate, which are separated from the first parts, by the second discharge unit, thereafter by removing the solvent from the droplets of the first liquid material arranged on the first parts, using the removal unit for solvent removing.

Film forming device, film forming method, and method for manufacturing electronic appliance

A multifunction electronic analog timepiece includes a face and a plurality of indicators positioned on the face for displaying at least two time keeping functions. At least two step motors are provided for driving the plurality of time keeping function indicators. The time keeping function indicators are arbitrarily disposed about the face dependent upon the number of step motors and position of step motors required to drive the indicators. A microcomputer is provided and includes a program memory for storing software instructions for controlling the step motors.

Multifunction electronic analog timepiece

An apparatus for charging a power storage device provided within an electronic device. A power source provides direct current which is alternated in direction through a pair of primary coils for inducing alternating current in a secondary coil of the electronic device. The pair of primary coils are fixed to a coil yoke all of which are supported within a casing of the apparatus. During charging of the power storage device, the electronic device is mounted to the outside surface of the casing whereby substantially all of the magnetic flux of the magnetic field produced by the pair of primary coils flows through the secondary coil and coil yoke. The frequency of the oscillating signal is preset to provide the maximum induced current which will not adversely affect the movement of the analog mechanisms within the electronic device.

Charging apparatus for an electronic device

In an electronic analog timepiece an automatic sequence of events determines the proper magnitude of a detection resistor which is used in series with the motor coil so as to determine whether in normal operation the rotor is rotated or not when driven. A detection resistor is used in series with motor coil but only after a fixed time has passed from initiation of detection current flow. The detection resistor is logically variable and selected automatically in accordance with the motor's mechanical load at the time of switching on the power source or releasing the analog timepiece from a resetting operation. The resistance is formed part of the integrated circuit.
