Abstract: PURPOSE:To extract a desired program rapidly, by providing a memory which receives a television multiple signal, where different binary information are superposed on plural horizontal scanning lines in the vertical blanking interval, and searches and stores numbers of respective horizontal scanning lines. CONSTITUTION:In case that desired binary information selected by a selecting circuit 34 is superposed on the 20th H, an increment pulse generating circuit 26 is controlled by the function of a timer B36 to count up a counter 16 and a gate pulse for each H is obtained for detection on the 17th H-the 19th H. When identification signals IDC coincide on the 20th H, a program code signal which a slice circuit 4 outputs is stored in a program latch circuit 31. A program code designated by the selecting circuit 34 is stored in an program designating circuit 33, and both program codes are compared by a coincidence detecting circuit 32; and if they coincide with each other, the timer B36 is cleared. Hereafter, only the signal on the 20th H is extracted. Thus, horizontal scanning lines for selected programs are searched and stored, and hereafter, only signals of these horizontal scanning lines are extracted automatically.

IPC: G03B42/02
Filed: 1982-08-18
Abstract: PURPOSE:To see steroscopically one plane picture with left and right eyes as different pictures because of the difference of picture element transposition, by arranging continuously minute boundary part, where the light is turned at an angle by transmission refraction, and minute plane parts alternately on the first and the second face parts. CONSTITUTION:On respective one face of the first and the second transparent plane- plate transmission bodies 2 and 3, many V-shaped concave minute boundary parts 4 and 6 having the same pitch are formed in the shape of mosaic, and these parts and minute plate parts 5 and 8 are arranged alternately and continuously. A light a'1 from a picture element P1 of a picture 1 is refracted at a point Y of the plane part 5 and is emitted from a point Y' on the side face of the boundary part 6 after two refractions, and therefore, the picture element P1 is seen with a line of sight a1 by which a picture element P2 should be seen from an eye A. A light a'2 from the picture element P2 is shifted in the direction of an arrow S, and a picture element P3 is seen with a line of sight a2. Consequently, one plane picture is seen as different pictures with left and right eyes because of the difference of angle of both eye's lines of sight and the difference of picture element transposition by turning of the transmitted light, and the picture can be seen stereoscopically in a continuous wide range by a great many people.

Title: Signal multiplexing circuit
Inventor: NIKORASU TSUIAKASU
IPC: H04M11/06
Filed: 1985-06-28
Abstract: Bidirectional communication of voice analog and data message signals over a two wire telephone line (16) that inter-connects several electronic key telephone station sets (18) with a digital access circuit (13) of a central data and voice communication facility (19) is achieved by a multiplexing circuit that functions either as a set interface (17) for a telephone or as a line card interface (11) for the access circuit (13). Data messages originating at a key pad (52) of any set or which are input to an interface bus of the multiplexing circuit are stored in a shift register (23) for subsequent modulation of a high band carrier signal, but only one interface (11) (17) may enter a transmission mode at one time. Transmission priority is therefore assigned by a controller (25) to the interface (11) (17) that first attempts transmission on an inactive line (16), i.e., in the absence of the carrier signal. With transmission initiated, all other interfaces (11) (17) enter a monitor mode to listen but not act on the transmitted message. Errors in transmissions caused by line noise, or collision transmissions between two or more interfaces (11) (17) are resolved via message transactions between the interfaces. Retransmission priority based on the unique addresses of the calling interfaces (11) (17) resolves collision issues with priority going to the lowest address. Controllable transmit and receive equalizers (36') (37') define analog signal paths in the line card interface (11) and are always in an operational mode. Corresponding equalizers (36) (37) in the set interface (17) are normally quiescent and become fully operational only after a correct address match between calling and called interfaces (11) (17) occurs and the called interface responds with a line signal acknowledging receipt of a valid message. A codec (20) may then be enabled and bidirectional communication between a set (18) and the facility (19) is established with voice and signalling being frequency division multiplexed on the line (16).

Filed: 1977-12-02
Abstract: PURPOSE: To simplify the cutting and dividng of a fault part and the analysis of fault data by checking the check timing of a partiy check circuit with both control signals A and B separately.  
     CONSTITUTION: Register 2 fetches the contents of input pulse 1 with control signal A and flows them to the output bus with control signal B. One bit among the data of this register is used as a parity bit, and each FF of the register is connected to parity checker 5. At this time, the parity error is detected by using only signal B as check timing of the parity error as to conventional technique, but signal A is also used here. Two latching FFs by these control signals are provided and when either one is set, the other is locked to make it possible to set only one. Consequently, it can be judged whether the fault occurs by signal A or B.

Title: Direct-coupled amplifying circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/45
Filed: 1982-08-20
Abstract: PURPOSE:To set the DC output voltage perfectly at zero, by floating a positive/ negative power supply from an earth in terms of DC and having a 100% DC feedback factor without giving any time constant to a feedback loop. CONSTITUTION:A positive/negative power supply (+ or -VCC) supplied to a circuit floats from an earth in terms of DC, and the junction between a positive power supply +VCC and a negative power supply -VCC is earthed via a capacitor CB having sufficiently large capacity. The DC output voltage (output offset voltage) is stabilized since the DC feedback factor is set at 100%. Furthermore no DC current flows to resistances Rf, Rg and Ri respectively since the power supply + or -VCC has DC floating from the earth. Thus it is possible to set the DC output voltage perfectly at zero. The offset voltage of an input differential amplifier emerges at a gate of the input side and then cut by an input coupling capacitor Ci.

Title: Multiple information processing system
Inventor: OOTAKI SABUROU
IPC: H02J1/00
Filed: 1982-08-20
Abstract: PURPOSE:To protect data in an information processor in case of abnormality of a power source by providing a request arbitration adding circuit having specific functions in a main storage device. CONSTITUTION:A power source device 1, when detecting power source abnormality, reports the abnormality to the information processor 3 and main storage device 5 through a power source disconnection advance notice line 100. The information processor 3 once receiving the report starts enqueuing its own information in the main storage device 5 through a main storage access request line 102. The main storage device 5, on the other hand, inputs the report of the power source abnormality by the request arbitration adding circuit 6. This adding circuit 6 accepts only a main storage request from the information processor 3. Therefore, the information in the processor 3 is enqueued at a high speed. Further, when a power source disconnection is supplied to the main storage 5 through a signal line 108, the operation of the adding circuit 6 is reset. Thus, the data in the information processor during the power source abnormality is protected.
