Title: Method and device for preparing three-dimensional body
Inventor: CHIYAARUZU DABURIYU HARU
IPC: B29C35/08
Filed: 1989-05-01
Abstract: PURPOSE: To produce a three-dimensional object without the need of producing design layouts and drawings, and of producing drawings and tool for processing by applying energy such as a spot of UV light or the like as a graphic pattern to a working surface of a fluid medium to form thin, solid, individual layers on the surface for programming under the control of a computer or the like. CONSTITUTION: A three-dimensional object is generated by creating a cross-sectional pattern of the object to be formed on a surface of a fluid medium capable of altering its physical state in response to synergistic stimulation. Adjacent laminae, representing successive adjacent cross-sections of the object, are automatically formed and integrated together to provide a step-wise layer buildup of the object, whereby a three-dimensional object is formed and drawn from a substantially planar or sheet-like surface of the fluid medium during the forming process. Complex forms are more easily created by using the functions of a computer to help generate programmed commands and to then send the program signals to a stereolithographic object forming system.

Title: Clock generating device
Inventor: NAGAI TETSUYA
IPC: H03L7/093
Filed: 1986-05-19
Abstract: PURPOSE:To prevent the out of synchronism of a subsequent clock even with a fault in the input clock by inserting a limiter circuit between a low pass filter and a voltage controlled oscillator of a phase locked loop so as to limit the output frequency range of a clock generator. CONSTITUTION:A phase comparator 10 compares the phase of an input clock (d) with that of an output clock (e), and if the phase of the output clock (e) is delayed to that of the input clock (d), an output voltage is incressed, and if advanced, the output voltage is decreased. Then the output frequency of the voltage controlled oscillator 14 is changed and the phase difference of them is decreased. Then the system is stable when the two phases are coincident, and even if the frequency of the reference input clock (d) is varied largely due to a fault or the clock is interrupted, a very high/low voltage is not fed to the input of the voltage controlled oscillator 14 by the limiter circuit 13, resulting in narrowering the input voltage range. Thus, the output frequency fluctuation of the voltage controlled oscillator 14 is decreased.
