Title: Synchronizing signal detection system
Inventor: YOKOGAWA FUMIHIKO
IPC: G11B20/14
Filed: 1987-09-16
Abstract: PURPOSE:To detect correctly a synchronizing signal by masking the intermediate period of two edge pulses at the stable detection of a synchronizing signal in comparing the interval of the two edge pulses of an input signal with a reference interval so as to detect the synchronizing signal. CONSTITUTION:The edge pulse of the input signal is detected to detect the interval of each edge pulse. When the interval between a 1st edge pulse and a 2nd edge pulse is equal to the preset prescribed reference interval, a detection signal for the synchronizing signal is outputted. When the synchronizing signal is detected stably, the intermediate edge pulse between the 1st edge pulse and the 2nd edge pulse is masked. The edge pulse at the initializing (the synchronizing signal is not stably detected) is not masked. Thus, the erroneous detection of the data as the synchronizing signal is prevented and even if an edge pulse due to a defect of a disk takes place in the middle of the reference interval, the synchronizing signal is detected stably.

IPC: H03K19/0185
Filed: 1982-12-22
Abstract: PURPOSE:To speed up a semiconductor device by improving the unsharpness of leading and trailing waveforms in a line having a large RC distributed time constant by means of the provision of a simple circuit element. CONSTITUTION:When an output potential of a word line driver WD rises as shown in Fig. (a), the leading at a point (b) is unsharpened. When the potential at the point (b) exceeds a threshold value Vth1 of an inverter I1, the potential at a point (c) drops to L level. The potential at the point (c) remains at H level and that of a point (d) remains at L until the potential at the point (a) goes to H level, and when the potential at the point (c) goes down to L from this state, the potential at the points (c) and (d) both goes to L so as to turn on P-channel TRP1, P2. Then, the potential at the point (b) rises rapidly to a power supply Vcc. N-channel MOS-TRN1, N2 and inverters I3, I4 improve the unsharpness of the trailing similarly as stated above.

Title: Manufacture of semiconductor single crystal layer
Inventor: KANBAYASHI SHIGERU
IPC: H01L21/208
Filed: 1988-09-20
Abstract: PURPOSE:To contrive improvement and the like of characteristics of an element by forming grooves in a silicon thin film in the direction that is parallel to a beam scanning direction and separating silicon thin film into several parts before performing a fusion-recrystallization process, thereby forming a protective insulating film in the grooves and on the silicon thin film. CONSTITUTION:An SiO2 film 11 of 2mum thickness is deposited on a face-oriented single crystal silicon substrate 10 by a CVD process and then, an opening 12 which acts as a seed in the case where recrystallization is performed is formed by the use of the water solution of ammonium fluoride. Then a polycrystal silicon film 13 of 0.4mum thickness is deposited on the SiO2 film 11 and in the opening 12 by the CVD process in which the thermal decomposition of silane is used. Subsequently, grooves 14 are formed in the silicon film 13 by the use of reactive ion etching to separate the polycrystal silicon film 13 into stripes in such a way that each stripe is 30mum or less in width and the stripes are spaced about 2mum apart. The manufacturing work of this element is thus completed by forming an SiO2 film 15 of 0.5mum thickness on the silicon film as a protective insulating film. Therefore, no silicon is cohesive when it is molten through the irradiation of electron beam.
