Title: Digital signal coding method and system, signal recording medium and signal transmission method
Inventor: KATO MOTOKI
IPC: H04N21/242
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate deterioration in signals by safely planning a multiplexed schedule, even if a delay of a buffer for a coded signal is decreased. SOLUTION: An input video signal from a terminal 10 is fed to a frame memory 11, an image-coding controller 12 reads a video signal S11 from the frame memory 11 to calculate an assigned coding bit amount S12 and an image coding parameter S17 in the case of coding each image. A video encoder 13 conducts coding processing based on the information sets S12, S17. Furthermore, the assigned coded bit amount S12, and the coded parameter S17 are also fed to a multiplexed scheduler 22, in which a multiplexed schedule is planed in such a way that failures in a buffer of the decoder are not caused.

Title: Magnetic recording/reproducing apparatus
Inventor: NIRASAWA TAKAO
IPC: G11B20/06
Filed: 1994-07-21
Abstract: PURPOSE:To reduce external elements of an IC circuit and reduce the system cost by setting a constant voltage circuit consisting of transistors and a resistor which is connected via a resistor to one end of a recording/amplifying circuit. CONSTITUTION:A head L is connected to a Tr1 at the last stage of a recording/ amplifying circuit, and a diode Di1 is connected between one end of the head L and a power source 1. A constant voltage circuit is constituted of transistors Tr2-Tr5 and a resistor R2. A resistor R1 is connected to one end of the head L and one end of the constant voltage circuit. In this constitution, even when a current flowing in the head L is changed at a certain frequency, the constant voltage circuit functions as a damping resistance without being influenced by the change of the current. Therefore, the frequency is less changed and no deterioration resulting from distortions is produced. Moreover, a capacitor and a resistance as conventionally employed external elements become unnecessary, so that the system cost is reduced.

Title: Electrodestructure of compound semiconductor and method for forming the same
Inventor: TAKATANI KUNIHIRO
IPC: H01S5/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To stably form a low resistance ohmic electrode by successively depositing a first layer made of a compound of a first metal and N, and a second layer made of the first metal on a GaN based compound semiconductor layer to form an intermediate layer between an electrode metal and the semiconductor layer. SOLUTION: An n-type GaN layer 101 is epitaxially grown on a sapphire wafer to purify the surface thereof. Setting the wafer in a main chamber of an electron beam(EB) vacuum deposition device, the chamber is vented in a high-vacuum manner. Thereafter, heating treatment is performed until the temperature of the wafer becomes around 200 deg.C, followed by forming a Zr nitride layer 102 and a Zr layer 103 by an EB vacuum deposition method. Like this, by using the Zr nitride layer 102 as an electrode which is in direct contact with the n-type GaN layer 101, contact resistance is reduced, and the dispersion of characteristics can be controlled. Further, bonding strength at each of the interfaces between the layers is so high that the mechanical strength of the entire electrode structure can be kept in high level.
