Title: Character-pattern signal receiving unit
Inventor: TSUBOKA HIDEKAZU
IPC: H04N7/025
Filed: 1978-09-25
Abstract: PURPOSE: To simplify a circuit constitution by using a microcomputer to convert character pattern signals, which have control information added for every block and are sent in different transmission speeds by different transmission mediums, to character pattern signals to be displayed.  
     CONSTITUTION: Character pattern data and clocks are reproduced from character pattern information, which are transmitted through telephone line 1, by demodulator 4 and are outputted to terminals 5 and 6. In a character multiple broadcast, information transmitted from VIF11 has vertical and horizontal synchronizing signals separated by synchronizing branch circuit 14, and control information and data of character broadcast are outputted to terminal 17 by sampling gate generation circuit 15 and AND circuit 16. Then, the chrominance subcarrier is reproduced by color synchronization circuit 19 and is supplied to clock generation circuit 20 to generate clock signals to sample character signals and output them to terminals 17 and 18. These signals are converted to character pattern signals displayed on CRT31 through switching circuit 7 by the control of CPU35 of a microcomputer and are stored in RAM73 and are displayed on CRT31 through display signal generation circuit 28 and display signal switching circuit 29.

Title: Semiconductor integrated circuit
Inventor: IWAHASHI HIROSHI
IPC: H03K19/00
Filed: 1981-07-29
Abstract: PURPOSE:To reduce the consumption of power supply current in an assured way, by providing a means for supplying voltage higher than the gate voltage to the source of a control depression type MOS transistor in a power-down mode. CONSTITUTION:A control depression type MOS transistor TR11, a load TR12 and a driving enhancement EH type MOSTR13 are connected between power supply VC and the earth. At the same time, an EH type MOS controlling TR14 is connected in parallel with the TR13. Both the TR11 and TR14 receive gate control with a power-down signal-PD and a signal PD. The signals PD and -PD are set at 1 and 0 respectively in a power-down mode. Thus the TR14 conducts and voltage VSO is applied to the source of the TR12 from a voltage generating circuit 21, and the voltage VSO is set at a certain level that is decided by the ratio of the conduction resistance of TRs22-24 of the circuit 21. The threshold voltage of the TR12 is set larger than that of the TR11. Thus the VSO is supplied to the source of the TR11 via the TR12, and the gate of the TR11 is equivalently turned negative. Thus the TR11 is assuredly cut off to reduce current consumption.

Title: Interfacial evaluation of magnetic laminating thin film
Inventor: MAEDA ATSUSHI
IPC: H01L43/12
Filed: 1988-05-18
Abstract: PURPOSE:To analyze the interfacial state of magnetic laminating thin films in a short while by means of non-destructive analysis with high accuracy as well, by obtaining a value of the interactional energy of magnetic dipoles between pure magnetic and diffusion interfacial layers. CONSTITUTION:When microwaves are applied to thin films in a laminating structure between magnetic and non-magnetic layers A and B, energy levels of constituent elements undergo fission. Further, if a magnetostatic field is applied at a right angle to the microwaves and its application makes lengths of the microwaves vary, split energy due to the microwaves coincides with the energy of the magnetostatic field. Then, electron spin resonance(ESR) takes place, resulting in absorption of energy. In this way, a value of the interactional energy of magnetic dipoles in pure magnetic and diffusion interfacial layers A and C is obtained by measuring the width of an ESR absorption line and then, the number of layers composing the diffusion interfacial layers C and an existence probability of magnetic ions are obtained by calculating the foregoing the value of the interactional energy as well as the number of layers composing the magnetic layers which become known in advance. Thus, the interfacial state of magnetic laminating thin films are evaluated in a short while by means of non-destructive analysis with accuracy of 0.1 atomic layer as well.
