Title: Clock regenerating device
Inventor: MORIMOTO TAKESHI
IPC: H04N5/95
Filed: 1983-12-26
Abstract: PURPOSE:To generate a stable clock by controlling the internal state of a frequency divider even if rapid phase change such as a skew error takes place in a synchronizing signal to absorb the phase fluctuation. CONSTITUTION:The time interval between the initial internal state D and the 2nd internal state D is a time width generated as a skew error from the point of time of generation of a skew until a control signal 32 is given to a 1/N frequency divider 5 from the observation of the internal state 28, then the clock over-count is compensated. Thus, even if a skew is generated, the relation of phase between an output phase of the 1/N frequency divider 5 and the phase of an external synchronizing signal 1 is coincident with the two phase relations when a PLL is operated stably. Then only the phase shift due to skew error is compensated, the phase of a trapezoidal wave 27 and the phase of the synchronizing signal 1 afterward are at a stable position, and even if the sampling is conducted at a PC2 after correction of the internal state of the 1/N frequency divider 5, no effect is given onto the oscillating frequency of a VCO4 with an error voltage of steadly-state. Thus, no unstable regions of the PLL is caused.

Title: Latch circuit
Inventor: YAMAGUCHI SEIJI
IPC: G11C11/412
Filed: 1983-12-26
Abstract: PURPOSE:To obtain a high-speed latch circuit by providing two inverters and a connecting means which is connected between outputs of both inverters and connects said outputs electrically according to a control signal. CONSTITUTION:MOS Transistors (TR) P11 and N11 constitute an inverter for an input -S2 and an output S2, and TRs P12 and N12 constitute an inverter for an input S2 and an output -S2. Then S2 and -S2 are short-circuited electrically by TRs N3 and N4, and N5 and N6 with a control signal phi. The potentials of S2 and -S2 approach each other while phi is at ''H'' and the potential difference is held by on resistances of TRs N3 and N4, and N5 and N6. Further, phi is connected to gates of TRs N7 and N8, so threshold voltages of S2 and -S2 are lowered as compared with the constitution of only TRs P11 and N11, and P12 and N12 while phi is at ''H'', and settable to, for example, a half as high as a source voltage.

Title: Method of evaluating semiconductor device
Inventor: NOMA JUNJI
IPC: H01L21/66
Filed: 1990-09-19
Abstract: PURPOSE:To evaluate diffusion-implantation depth with higher accuracy by diffusing or implanting impurities into a semiconductor substrate having quantum well structure and observing the disappearance of a corresponding photoluminescence emission peak by quantum well disordering induced by a diffusion or implantation. CONSTITUTION:A plurality of emission peaks corresponding to each quantum well layer appear because photoluminescence emission wavelengths differ by the layer thickness of each layer on multiple quantum well layers in which a plurality of the quantum well layers 1 in different thickness are formed in a multilayer. When impurities are diffused or implanted to such multiple quantum well layers 1-5, all quantum well layers existing between a section up to a diffusion or implantation front from a substrate surface are disordered, and photoluminescence emission peaks corresponding to the quantum well layers disappear. Accordingly, the disappearance of any peak is conformed, thus determining reaching up to any quantum well layer of the diffusion or implantation front while evaluating the position of the front, the depth of the diffusion or implantation.
