Title: Video signal discriminating circuit
Inventor: WATANABE MASAHIRO
IPC: H04N5/44
Filed: 1982-05-10
Abstract: PURPOSE:To obtain the circuit mainly comprising a horizontal AFC and a horizontal oscillator used for a television receiver, by comparing both phases of an oscillation pulse and a horizontal synchronizing signal, detecting the difference and forming a prescribed output signal at the input of a non-video signal. CONSTITUTION:When a normal video signal exists, the phase of the horizontal oscilation pulse and the horizontal synthconizing signal is coincident, the horizontal AFC circuit section 2 is operated normally and the horizontal oscillation frequency is adjusted in the horizontal locking range, then a zoero voltage is outputted to an output terminal 17 of a phase detection circuit 16. Thus, a suitable capacitor circuit is provided, the peak value of the output pulse is held, then since no video signal exists, that is, when the horizontal synchronizing signal does not exist, a pulse in synchronizing with the horizontal oscillation pulse is outputted. When the horizontal synchronizing signal does not exist and only noise is inputted, since a pulse having noise is outputted to a itme axis of the horizontal oscillation pulse, a DC voltage is obtained, it is discriminated from the case at zero voltage and the presence of the video signal is discriminated.

Title: Reception circuit having surface acoustic wave device
Inventor: FUKIHARU EIICHI
IPC: H03B5/32
Filed: 1994-04-18
Abstract: PURPOSE:To compensate the temperature deviation of frequency by forming a SAW resonator which contains the frequency converters of two stages and oscillates the reference frequency signals of local oscillations of both converters on a piezoelectric substrate that is common to the SAW resonator of an IF filter. CONSTITUTION:A local oscillation circuit LO 5 sends the frequency of a SAW element 2 to a 1st frequency converter FC 7 as a local oscillation signal via a multiplier 8. The FC 7 sends a 1st IF signal converted by the upper local oscillation to a 1st IFF 1. The IFF 1 consists of a SAW element and sends the signal of a pass band to a 2nd FC 9. The FC 9 outputs the output of the LO 5 as a lower local oscillation signal together with a 2nd IF signal. The SAW elements of the IFF 1 and the LO 5 are formed on the same piezoelectric substrate to secure the same frequency change to the temperature. Therefore no deviation is produced between the 1st IF frequency and the pass frequency of the IFF 1 against the temperature. Furthermore the 1st IF frequency and the local oscillation frequency of the FC 9 have the same change to the temperature. As a result, the 2nd IF frequency has no temperature change.

Filed: 1993-04-07
Abstract: PURPOSE:To improve the precision and to reduce the labor of calculation by letting a cluster which consists of the closest surface atoms of an absorption seed and atms adjacent to surface atoms be a surface model and reducing through the use of localizing orbits the umber of molecular orbits to become the object of electron correlations. CONSTITUTION:Molecular orbits obtained as the result of molecular orbit method calculation (105) are converted to obtain the localizing orbits (106), and they are adopted or rejected based on their spatial spreads to select or reject the localizing orbits to be used in calculation of electron correlations (107). Thus, the labor of calculation of electron correlations is considerably reduced. In this case, molecular orbit calculation (105) is performed by the cluster consisting of the closest surface atoms of the absorption seed and all of atoms adjacent to them, and electron correlations are calculated by localizing orbits based on the calculation result, thereby simulating the frequency, the reaction process, etc., on the surface with a satisfactory precision. Even when the surface model is more simplified to use a cluster consisting of only the closest surface atoms of the absorption seed, a sufficient precision is obtained with respect to calculation of the structure and the frequency of the absorption seed.

Title: Local network
Inventor: NAKAMURA TOSHIMICHI
IPC: H04L1/18
Filed: 1982-05-15
Abstract: PURPOSE:To perform internode communication with high efficiency without collision of signals, by allowing a transmitting node which detects a reception negative acknowledge signal (NACK) not to resends a signal immediately, but to transmit the same signal again when obtaining the right of transmission after one round. CONSTITUTION:The cyclic transfer of the right of transmission is carried out all the time without reference to whether data to be sent to each node is in queue or not and no signal collision is caused, so the efficiency is improved eventually. Specially, when data reception (or confirmation) is disabled, that is dealt with by NACK transmission, so time loss is minimized. A figure shows that the right of transmission is passed from a node N-1 to a node N and what kind of signal the node N sends out. When the node N finishes data transmission, the transmission is stopped for a specific time to indicate a data end and if there is a receiving node which fails to confirm data during said period, the NACK is sent out. This state is shown by a broken line. The node N sends out the address of a node N+1 a specific time later to pass the right of transmission to the node N+1.
