Title: Hermetic terminal for laser diode and manufacture thereof
Inventor: NAKANIWA TAMOTSU
IPC: H01R43/20
Filed: 1992-09-01
Abstract: PURPOSE:To prevent damage of a mounted semiconductor laser (semiconductor chip) by heat by providing a laser diode installation table comprising metal of a higher heat conductivity than that of metal composing a shell. CONSTITUTION:A metal shell 21, a laser diode installation table 24 of which lower part (cylindrical part) is formed embedded to reach a bottom surface in the shell, and a grounding connection terminal 26 having a grounding lead wire 25 at a recessed part formed at a lower part of the table 24 are brazed. A part between a surface of the lower (cylindrical) part of the table 24 embedded in the shell 21 and the shell 21 is brazed with a brazing material 29. The table 24 is formed of metal (copper, for example) having a larger heat conductivity (or, favorably, having a larger heat capacity in addition) than that of metal material composing the shell 21. Heat resistance is set extremely small compared to that of a conventional device of iron, thereby damage is not given to a semiconductor chip (laser diode) by heat at the time of light pickup action.

Title: Node output control system
Inventor: SAITO AKITOSHI
IPC: G06F13/42
Filed: 1994-09-29
Abstract: PURPOSE: To reduce the power consumption by eliminating the charge/discharge of a useless node by providing a node potential supervisory and control means for continuously outputting a potential stored in a storage means onto the node when it is detected that no potential is outputted onto the node. CONSTITUTION: The node potential supervisory and control means is composed of a buffer 3, node use decoder 4 and node use monitoring circuit 5 and the node output control circuit is composed of the node potential supervisory and control means and a delay circuit 2. In the case of changing the potential on a node 1 according to a clock signal with this configuration, the potential outputted onto the node 1 in each clock cycle is stored by the delay circuit 2 and the potential on the node 1 is monitored by the node use monitoring circuit 5. When it is detected that it is not necessary to output any potential to the node 1, the output potential of the delay circuit 2 is controlled so as to be continuously outputted onto the node 1. Thus, the useless voltage change of the node at the time of switching from the use of the node to the non-use of the node can be suppressed.

IPC: H04N19/70
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To convert a sub-picture use video signal into coded data according to a precribed format. SOLUTION: A sub-picture use video signal Ss reproduced by a VTR(video tape rearder) is given to a variable length coder 11, and a reproduction time code TC is given to a time coder reader 12.

Title: Psk modulator
Inventor: TAKADA OKIYUKI
IPC: H04L27/20
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent extension of the circuit scale by conducting PSK(phase shift keying) modulation without separating a phase angle into I, Q signals. SOLUTION: An NRZ signal received by a terminal 21 is given to an NRZ-θ conversion section 24, and an oversample clock received by a terminal 22 is given to a roll-off filter section 25 and a gamma generating section 26. The conversion section 24 provides an output of a phase angle θ to the filter section 25, in which a time change in four phases of the phase angle θ is gradually changed by a roll-off function and the resulting phase θ is fed to the generating section 26 and a DDS 27(direct digital synthesizer). A gamma in 8-bit generated in response to a phase angle θ' by the generating section 26 is converted into an analog control voltage by a D/A converter section 28 to vary an attenuation of a variable attenuator 29 so as to apply variable control to a signal envelope from the DDS 27.  Then the attenuator 29 outputs a QPSK(quadrature phase shift keying) signal of the envelope corresponding to the gamma from a terminal 30. Since one system of the filter 25 and the conversion section 28 is enough, the extension of the circuit scale is prevented.
