Abstract: PURPOSE:To form a transistor by only one ion implantation and avoid a leakage current from a diffused layer to a semiconductor substrate caused by defects produced by ion implantation easily by a method wherein the thin impurity diffused layer of an LDD structure is formed through a polycrystalline silicon film formed after a gate electrode is formed and so forth. CONSTITUTION:After the gate insulating film 2 and the gate electrode 3 of a MOS transistor are formed on a semiconductor substrate 1, a polycrystalline silicon film 4 is formed on the surface of the semiconductor substrate 1 including the gate electrode 3. Then N-type or P-type impurity is diffused into the polycrystalline silicon film 4. Then the whole polycrystalline silicon film 4 is oxidized to form a polycrystalline silicon oxide film 5 and, at the same time, the impurity in the polycrystalline silicon film 4 is diffused to form thin impurity diffused layers 6. After that, the whole polycrystalline silicon oxide film 5 is etched to form side walls 5a on both the sides of the gate electrode 3. Then high concentration impurity is diffused into the semiconductor substrate 1 to form high impurity concentration diffused layers 8.

IPC: H04N1/00
Filed: 1988-03-25
Abstract: PURPOSE:To execute the dividing and transmitting of picture information and to correspond to multi-quantity information transmission by sending a temporary transmission interrupting signal from a transmitting side with in a limit time and obtaining a stand-by condition in a receiving side when this interrupting signal is received. CONSTITUTION:When the transmission of an original is not finished even after the prescribed limit time passes according to a timer 10 of a facsimile equipment 1, a transmitter T sends a temporary interrupting signal PPS to a receiver R and next transmits a line disconnecting instruction DCN. Then, the transmission is temporarily interrupted. The receiver R obtains the stand-by condition when the signal PPS is received. After a constant time passes, the transmitter T executes re-transmission by the automatic re-transmitting function of a CPU3. The above-mentioned operation is repeated until the transmission and reception of the picture information is finished. When the transmission of the picture information is finished, a procedure ending signal EOP is outputted from the transmitter T and when this signal is detected by the receiver R, a line disconnection instruction DCN is sent from the transmitter T. Then, the whole communication is ended.

Title: Elastic thin plate of laminate of carbon and titanium nitride
Inventor: HANEDA TOSHIO
IPC: B32B15/04
Filed: 1979-06-08
Abstract: PURPOSE:To form an elastic laminate thin plate suitable for a loudspeaker diaphragm by vapor-depositing a carbon film and titanium nitride film on a quartz base body and then by peeling them off. CONSTITUTION:On base body 1 made of crystalline quartz with smooth surfaces, thermally-decomposed carbon film 2 of hydrocarbon is vapor-deposited and titanium nitride film 3 is further vapor-deposited on it. Then, the vapor-deposited films are peeled from base body 1 at their interface to form an elastic laminate thin plate. Here, since carbon film 2 is hard to stick to base body 1, the peeling comes into effect easily at the interface between the both. Additionally, since carbon film 2 is close in thermal expansion coefficient to titanium film 3, thermal stress residing at the interface is small, and consequently the thin plate never deforms much. Thus, the elastic laminate thin plate suitable for a loudspeaker diaphragm can be formed.

Title: Digital phase locked loop oscillator
Inventor: KOYAMA TORU
IPC: H03L7/06
Filed: 1988-03-24
Abstract: PURPOSE:To take the pull-in range of a frequency wider than a conventional one even if the frequency-division rate of a reversible counter for suppressing a jitter is increased by providing a frequency control part between the reversible counter and a variable frequency divider. CONSTITUTION:The phase delay of an output signal continuously occur, for example, the counting result of the reversible counter 7 is decreased, and the frequency-division rate of the frequency divider 8 is correspondingly decreased. Since a frequency for coming to the frequency division rate (n-1) of the variable frequency divider 4 is increased as a result, the frequency of the phase forward shift of the output signal is increased, and it follows the phase of the input signal. Since the counting result of the reversible counter 7 holds a value at the time of locking when the phase of the output signal is in a locked state, the frequency of the output signal is held to the value at the time of locking and a mobile frequency follows the value at the time of locking so as to be changed. Thus, the pull-in range of the frequency is prevented from becoming narrow even if the frequency rate of the reversible counter 2 is increased for suppressing the jitter.
