Title: Optical shaping device
Inventor: TAKEHISA KIWAMU
IPC: B29C64/106
Filed: 1994-03-29
Abstract: PURPOSE:To produce a solid model in a short time without increasing the power consumption by a method wherein liquid crystal mask is employed and XeF excimer laser is used as light source. CONSTITUTION:As light source, XeF excimer laser 2 is used so as to get back laser beams 1 to parallel beams, the diameter of which is enlarged, resulting in irradiating the whole surface of a liquid crystal mask 4 at a stretch by passing the laser beams 1 through a convex lens 3a and then a convex lens 3b just before the liquid crystal mask 4. Next, the beams reflect at a polarization beam splitter 5, pass an imaging lens 6 and irradiate a UV-curing resin 8 in a vessel 7. In this case, since the liquid crystal mask is irradiated with the laser beams having a uniform intensity distribution, the UV rays having a uniform intensity distribution irradiates the UV-curing resin 8 so as to cure layer by uniform thickness in order to form a solid model. Further, since the XeF excimer laser is employed, no deterioration of liquid crystal mask occurs in a short period of time. Furthermore, since the laser beams 1 once enlarged irradiates the whole surface of the liquid crystal mask 4, processing time is remarkably reduced.

Title: Stabilized power supply circuit

IPC: H02J9/06
Filed: 1978-05-19
Abstract: PURPOSE: To eliminate the infuence of the scatter in the properties of circuit elements upon an alarm circuit and raise its accuracy, by detecting that a detected current of an error amplifier circuit is cut off when an output voltage has exceeded a predetermined level and then cutting off the output voltage by the alarm circuit.  
     CONSTITUTION: A reference voltage produced by a Zener diode Dz and the output voltage Vo are applied to the error amplifier circuit consisting of transistors Tr11, Tr14 and resistors R12, R15. The operating point of a transistor Tr13 is changed depending on the deviation output of the error amplifier circuit to stabilize the output voltage Vo. The alarm circuit consisting of transistors Tr15, Tr16 is provided for the output voltage. When the output voltage Vo falls below the predetermined level, the collector current of the transistor Tr14 decreases but the collector current of the transistor Tr14 increases. When the collector current of the transistor Tr14 decreases to a predetermined value, the transistor Tr14 is turned off. As a result, the transistor Tr16, Tr15 are turned off and the current supplied to the resistor R15 becomes zero, namely the power is cut off. The accuracy of the alarm circuit is thus  raised.
