Filed: 1993-06-21
Abstract: PURPOSE:To reduce the scale of a time base correcting circuit by enabling a memory to be variable the phase relation between the writing timing of data and the reading timing thereof in a certain degree. CONSTITUTION:A clock and a reference signal whose phase is synchronized with that of a horizontal synchronizing signal is outputted from a Hi-PLL circuit in a clock and reference signal generating circuit 10. An ADC 1 converts an input signal into a digital signal by using a clock outputted from the circuit 10.

A data processing circuit 2 executes the data processing of the input signal in accordance with the control signal generated from the circuit 5 and writes the processed data in the FIFO 3. The circuit 5 outputs also reference signal for determining the reading timing of the FIFO 3. Reading from the FIFO 3 and writing in a picture memory 4 are a series of operation and processed by the 2nd clock generated by a Lo-PLL in the circuit 10. Thereby a conversion circuit 6 synchronizes the FIFO reading reference signal outputted from the circuit 5 with I/O operation in/from the memory 4.

IPC: H01L21/3205
Filed: 1989-06-12
Abstract: PURPOSE:To prevent a formed polysilicon film from growing abnormally by forming a through-hole to an insulating film which is applied onto a silicon substrate, by injecting rare gas atom to the Si substrate and by forming a polysilicon film on a surface of the insulating film and in the inside of the through-hole. CONSTITUTION:A through-hole 3 is formed in an insulating film 2 which is applied onto an Si substrate 1. When rare gas atom 4 is injected to the through- hole 3 by ion injection method, etc., a crystal structure of the Si substrate surface is disturbed. Then, a polysilicon film 5 is formed on a surface of the insulating film 2 and in the inside of the through-hole 3. Since crystallinity of a surface of the Si substrate 1 inside the through-hole 3 is disturbed, it is possible to prevent growth of a projection which is a local single crystal growth usually generated when the polysilicon film 5 is formed inside the through-hole 3.

Abstract: PURPOSE: To prevent the collisions of drive pawls while miniaturizing a device by mounting lift plates guiding the drive pawls onto an interlocking plate to a ratchet accumulating energy to a drive spring in a device for an electric switch.  
     CONSTITUTION: A pair of lift plates 31a, 31b are installed at both flanks of a ratchet 2 by means of fixing bolts 32, and an interlocking plate 33 is mounted to a working shaft 1 in a rotatable shape through a bush 34 under a condition that holds the ratchet 2 from both sides. A sawlike continuous pawl similar to the ratchet 2 is formed on a circular arc surface at the free end side of the interlocking plate 33, and energized toward drive pawls 12, 13 at all times by means of a tension spring 35. Thus, even when the ratchet 2 is rapidly reversed by the emission of the re-accumulated energy of a drive spring 10, the continuous pawl of the ratchet 2 and the drive pawls 12, 13 do not collide mutually, and the strength of a material to be used is easily selected.
