Title: Complex resonant DC-DC converter and high voltage generating circuit driven in a plurality of frequency regions
Inventor: TAKAHAMA MASANOBU
IPC: H02M3/28
Filed: 2001-06-04
Granted: 2003-04-21
Abstract: A DC-DC converter includes a switching unit having a pair of switching devices or transistors, a resonant circuit comprising a capacitor, an inductor, and a primary coil of a converter transformer which serves as an inductor, a smoothing and rectifying circuit connected to a load in the secondary, an error amplifier for the output voltage, and a variable oscillator for varying the switching frequency according to the error voltage. The output of the variable oscillator circuit is supplied to the switching devices to provide a stabilized output voltage from the smoothing and rectifying circuit. The switching frequency during light loading is set at a frequency more than the resonant frequency which is mainly defined by the inductance and the interwinding capacitance of the secondary coil. The switching frequency to stabilize the output voltage during light loading is much higher than that during heavy loading, significantly reducing the exciting current component during light loading to enhance the energy conversion efficiency during light loading.

Granted: 2002-08-21
Abstract: A CVD device 1 of the present invention has a chamber 50 wherein a dome 5 is combined to an upper end of a tubular body 2. The body 2 is provided with a gas inlet 8a whereto film formation gas such as SiH4 is introduced and the dome 5 is provided with a gas inlet 8b.

Title: Fracture milling technique by laser for ceramic materials
Inventor: TSAI CHUAN-HUEI
IPC: B23K26/067
Filed: 2002-01-18
Granted: 2004-06-11
Abstract: This invention is a laser milling method for ceramic materials based on the principle of cracks linkage. Firstly, the side milling of the laser fracture milling technique is proposed. A focused laser is used to scribe two groove-cracks at the two intersecting surfaces of the material. Then, a defocused laser beam is applied along the groove-cracks to generate a great thermal stress, which makes the two groove-cracks link together. Secondly, the idea of fracture milling elements is proposed to shape a central cavity, which can be composed of the removals of a series of elements. A focused laser is used to scribe groove-cracks along the boundary of the elements. Then, a defocused laser beam is applied throughout the scribed lines. It generates the tensile stresses at the bottom of groove-crack and induces the linkage of the groove-cracks. The technique of the conventional laser milling requires high laser power to melt the material. On the contrary, the materials removal of this invention is due to the thermal stress generated by the laser heat.
