Title: Reproducing device
Inventor: FUKAMI TADASHI
IPC: F02B75/02
Filed: 1989-06-30
Abstract: PURPOSE:To detect a short unrecorded part on a magnetic tape even in fast searching by detecting whether or not a signal is recorded on a recording medium based on the output from a counter means. CONSTITUTION:When the fast searching is performed, RF signals SRF are reproduced from recorded parts ARC1 and ARC2, and no RF signal SRF is reproduced from the unrecorded part ANO. When the term of H level of a window signal SWN is conformed to the unrecorded part ANO where no RF signal SRF is recorded, it is detected as an error as a result of decoding of a C1 code, and an error signal SER of L level is outputted. Therefore, counting is not executed by a counter 5, and the output of the counter goes to an L level. A carrier signal SCR of L level is supplied successively from the counter 5 to an FF 10 during the 1/2 cycle of a switching pulse SWP. When an edge detection signal SEG is supplied to the FF 10, the signal SCR is fetched, and the output signal Sout of the FF 10 goes to the L level.

Abstract: PURPOSE:To clear the switching conditions of which system should be selected by monitoring switching conditions with respective switching circuits mutually, setting a weight to the switching conditions, generating a trouble weighting signal, comparing two trouble weighting signals and determining the switching condition. CONSTITUTION:An input monitoring part 2 detects the abnormality of information (a), (b), (c) and (d) and outputs it to a weighting part 4. An investigating signal generating part 3 outputs a signal (e) from the input monitoring part 2 and a trouble investigating signal (j) to the weighting part 4 and the weighting part of the switching circuit of other system. The weighting part 4 outputs them to a comparing part 5 and the comparing part of the switching circuit of other system as a trouble weighting signal (k) to change the condition at a time width T in proportion to the weight added to the trouble investigating signal (j). A comparator 5 compares two trouble weighting signals R and (n) and outputs a switching control signal (p). A switching part 1 switches information (a) and (b) and information (c) and (d) by the switching control signal (p) and the information (a) and (b) from an information source 11 is output.

Title: Video signal multiplex transmission system
Inventor: MISHIRO TOKIHIRO
IPC: H04J1/00
Filed: 1990-06-26
Abstract: PURPOSE:To increase a video signal channel number available of transmission per one satellite repeater without deterioration in a video signal by synthesizing both two-channels of video base band signals while one is subject to frequency shift so as to avoid the overlap of the signal onto the other video base band signal in terms of frequency. CONSTITUTION:A 1st video base band signal in received 1st and 2nd video base band signal is frequency-shifted at a frequency shift addition means 3 so that the band of the 1st video base band signal is not overlapped onto the band of the 2nd video base band signal, the shifted 1st video base band signal is added to the 2nd video base band signal to generate a multiplexed video signal. The multiplexed video signal is fed to a filter inverse frequency shift means 4 via an FM modulation transmission means and a reception FM demodulation means. The filter inverse frequency shift means 4 filters the 2nd video base band signal from the multiplexed signal to reproduce the 2nd video base band signal and applies inverse frequency shift to the frequency shift implemented on the sender side to reproduce the 1st base band signal.

Title: Display device
Inventor: MAKITA YOSHIO
IPC: H01J29/62
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a display device in which no leak current is carried in the part of a sealant even when a high voltage is applied to an anode electrode by enclosing an anode drawing electrode in the sealant position with an insulating material so as not to make contact directly with the sealant. SOLUTION: An anode drawing electrode 21 is enclosed by a glass tube 20 so as not to make contact directly with a sealant 7 welded to an anode substrate 1 or a cathode substrate 2. The connection of the anode drawing electrode 21 to an anode electrode 15 is performed, for example, by nipping the tip of the anode drawing electrode 21 by the anode substrate 1 and the glass tube 20, and this nipping force is caused by the atmospheric pressure. Although an anode voltage of, for example, 2-5 kV is applied to the anode drawing electrode 21, no leak current is carried in the part of the sealant 7 since this electrode 21 does not make contact with the sealant 7.

Title: Data highway communication system
Inventor: TANAKA MASAKAZU
IPC: H04L12/43
Filed: 1979-12-25
Abstract: PURPOSE:To improve the efficiency of utilization of a loop transmission line by using time slots, assigned to respective nodes, among other random nodes in  common. CONSTITUTION:Node N11-Nj4 are constituted in a closed loop via transmitting circuit 9. To respective nodes, information processors P15-Pj8 are connected. Time slots T1, T2 and T3 on the loop are assigned for the reception of node N1, T4 and T5 for the reception of node N2, and Tn, Tn+1, Tn+2, Tn+3, and Tn+4 for the reception of node Nj. When a request for communication is sent from information processor P1 connecting with node N1 to information processor Pi connecting with node N1, P1 transmits an address signal to N1, which knows a time slot to be used. Once the time slot useable is secured, this time slot is used fixedly until the communication ends. Thus, the time slots assigned to respective nodes can be shared among random nodes and the efficiency of utilization of the transmission line can be improved.

Not more than 1.5mm. is effective as the thickness of the intermediate plate. The thermal expansion coefficient must lie between those of the semiconductor chip 3 and the substrate metal 1, and thermal resistance is also reduced when clad metals have excellent thermal conductivity.

Title: Wire bonding method for semiconductor device
Inventor: NAKAZAWA TSUTOMU
IPC: H01L21/60
Filed: 1988-07-07
Abstract: PURPOSE:To prevent a bonding wire which is bonded beforehand and a catapillar from contacting with each other even if the pitch between electrodes is narrowed by executing bondings one after another from electrodes at the periphery of each side of a semiconductor chip to electrodes at the center. CONSTITUTION:The electrode 4 of a semiconductor chip 3 and the inner lead part 5 of a lead frame 1 are bonded with a bonding wire 6. And these bondings are done one after another from the electrode 4 at the periphery of each side of the semiconductor chip to the electrode 4 at the center. Accordingly, the shortest distance between the bonding wire which was bonded beforehand and the center of bonding to be bonded next becomes the pitch between the electrodes of the semiconductor chip. Hereby, if it is an interval between pitches which is a little larger than the radius of a catapillar 7, the wire bonding can be done by preventing the contact between the preceding bonding wire 6 and the caterpillar 7.
