Patent JP-S58164259-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: OOTSUKA HIDEO
IPC: H01L27/10
Filed: 1982-03-24
Abstract: PURPOSE:To prevent an erroneous operation of a semiconductor device due to minority  carrier by forming an N<+> type region on the prescribed part of the boundary between  a P type epitaxial layer formed with a peripheral circuit and a P<+> type substrate of the lower layer of the P type layer. CONSTITUTION:The mask of an SiO2 film photoetched in a lattice shape is covered on  a P<+> type Si substrate 21 to form an N<+> type diffused layer 23, the mask is then removed, and a P type layer 22 is formed by a CVD method. An MOSFET 51 and a capacitor 52 are formed on the layer 22, and an insulating film 53 is covered. The layer  23 is disposed in the boundary between the layer 22 at the periphery of the FET 51  which is operated in the saturated range and the substrate 21, but not presented directly  under the FET 51. Accordingly, those directed toward the part directly under that of  the impact ions which are produced by the drain of the FET 51 do not arrive at the capacitor, but those directed toward the periphery are reflected on the boundary, and  arrived slightly at the capacitor. Thus, an erroneous operation is less, and charge retaining time can be prolonged. Further, unnecessary minority carrier is collected by the buried layer, and the diffusion is reduced, and the impact ions produced at the peripheral circuit is particularly effectively removed, thereby reducing the interference between  the elements.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To make the number of packets to be reproduced and the number of packets to be outputted coincide without performing a special synchronization processing at the time of reproducing by performing a recording while allowing the revolution cycle of a rotary head to be synchronized with the transmission time information of packet data or the cycle of the time reference value to be included in the packet stream restored from data blocks. SOLUTION: At the time of recording, the packet stream of a compressed video signal is restored by performing the input control of data blocks with the bus reference clock of an oscillation circuit 107 synchronized with a synchronizing clock and operating timings of a recording and reproducing signal processing device, clock. are controlled by a timing circuit 105 based on the restored transmission rate. At the time of reproducing, a demodulation, the reproducing processings of an error detection and correcting, etc., and the transfer timing control of the packet stream in an input-output circuit 300 or the like are performed by making the internal reference clock generated in an oscillator circuit 108 an operation reference. Moreover, the output control to data busses is performed by the bus reference clock of the oscillator 107 similarly at the time of recording.

IPC: H01J11/10
Filed: 1982-03-23
Abstract: PURPOSE:To make the captioned panel to possess the sufficient brightness and have its  display quality enhanced without deteriorating the electrode, by continuing the discharge by means of an outside electrode-type display cell. CONSTITUTION:Transition electrodes 311-1N, 321-2N, 331-3N, 341-4N are commonly connected  in the panel in every transition electrode group 31, 32, 33, 34 and form one address cell.  A plus electric charge injected from an input electrode controls the transition electrode group 31, 32, 33, 34, then progressively transits over the transition electrode like 311  321 331 341 321 322, and reaches the predetermined address position. The center of  the transition electrode group 3 is perforated in order to obtain communicating tube 7  which connects the address cell 1 to the pilot cell 6; when the plus electric charge is  transferred to the transition electrode group 33 during its preserving period, an electrode 8 coated with a dielectric 2 is biased into minus, the plus electric charge is transferred into the pilot cell 6 through the communicating tube 7 and accumulated on  the electrode 8. After this accumulation, an electrode 9 coated with the dielectric 2 is  biased into minus and the electrode 8 is biased into plus, then the discharge is generated in the pilot cell 6.

Title: Synchronous code detector
Inventor: YOSHIMARU TOMOHISA
IPC: G11B20/10
Filed: 1989-02-27
Abstract: PURPOSE:To accurately perform the detection of a synchronous code with a simple circuit by counting the number of bit clocks, and resetting a frame detecting means by detecting a part of the synchronous code when a counted value is deviated from a prescribed range. CONSTITUTION:Data on one side read by an optical head 5 and binarized at a binarization circuit 9 is stored in a shift register 13 sequentially. Synchronous code detection circuits 15a and 15b are composed so as to take synchronism by detecting the synchronous code out of modulated data in the register 13, respectively, and resetting a frame counter 17 with the detecting signal. The circuit 15a detects only the 3/4 part of quadripartite synchronous code 0010000000100000, and the circuit 15b detects all of them i.e. 4/4 of the code. The counter 17 counts the number of bit clocks, and since the circuit 15a receives a gate signal from a window circuit 19a, it is reset by the detecting signal when the counted value goes to the value deviated by one bit. When the counted value goes to the value deviated by two bits, the counter is reset by the circuit 15b, however, it happens very rarely.
