Title: Microwave phase lock oscillator circuit
Inventor: TAKAHASHI MASARU
IPC: H03L7/18
Filed: 1995-04-06
Abstract: PURPOSE: To prevent phases from being synchronized with a frequency except a prescribed frequency and to facilitate adjustment operation for synchronizing the phases with the prescribed frequency. CONSTITUTION: Concerning the phase lock oscillator circuit in which a reference oscillator 2, and sampling phase detector 4, loop filter 6 and VCO 7 constituting a phase lock loop are arranged, a frequency divider 17 is provided to divide the frequency of an oscillated signal from this VCO 7 into N pieces and these N frequency-divided signals each are supplied to this sampling phase detector 4. Thus, a phase comparison frequency can be made 1/N in comparison with conventional one and the ratio of range of phase pull-in frequency to the phase comparison frequency is increased. Therefore, the phase lock is hardly synchronized except the target frequency and further, adjustment for phase lock is facilitated as well.

IPC: F21V11/16
Filed: 1995-04-10
Abstract: PURPOSE: To easily and economically provide a light shielding plate having a unidirectional light shielding property without degrading good appearance by a simple printing process by printing clear printing parts with a clear (a color with high reflectance) material on one side of a dark and transparent substrate while leaving fine non-printing parts (the substrate face). CONSTITUTION: A light shielding plate l is employed while being arranged in the way the side to be printed with a clear color A of a dark and transparent substrate 12 is set to face to the outside and the side in which no printing is carried out is set to face to the inside. Most of the light-rays from the outside are reflected in the clear color printed parts (a) to effectively shield visible light-rays and solar rays. From the dark inside, light-rays come to the clear color printed parts (a) after light- rays pass the dark transparent substrate in thickness direction and are reflected by the clear color printed parts after light-rays pass the thickness of the dark transparent substrate, so that eyesore reflected light-rays are decreased.  Furthermore, the outside can surely be seen through a window (b) to see through and which is formed in fine non-printed parts existing among the clear color printed parts. With this structure, a light shielding plate with unidirectional light shielding property can be obtained easily at low cost without deteriorating the good appearance.
