Title: Production of magnetic recording medium
Inventor: KOMATSU KAZUNORI
IPC: G11B5/845
Filed: 1988-01-18
Abstract: PURPOSE:To effectively obtain a magnetic recording medium having excellent orientability and excellent characteristics by suppressing the degree of spreading of the magnetic lines of force on the down stream side of a main magnet which executes magnetic field orientation by the magnetic force of auxiliary magnets provided on the down stream side of the main magnet. CONSTITUTION:The auxiliary magnets 6 are provided in such a manner that the N poles thereof oppose each other and the magnets open at a proper angle thetatoward the down stream side of the traveling direction of a base. The spread angle of the magnetic fields in the traveling direction of the base is, therefore, decreased in the part near the end edges of the base 2, by the repulsive force of the magnetic fields of the magnets 6, as shown by the magnetic lines x of force on the down stream side of the magnet 5, by which the parallel state of the magnetic lines x of force is maintained even at the place apart a certain distance from the magnet 5. Namely, the magnetic fields stable along the traveling direction of the base can be applied over the entire width of the base 2 in the region where the orientation is affected. The good orientation treatment is thus executed. The magnetic recording medium having the stable high squareness ratio and the excellent characteristics is thereby obtd.

Inventor: HASHIZUME TETSUSHI
IPC: C30B29/02
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To eliminate a problem that a method for producing the film of SiGe mixed crystal by changing the partial pressures of GeH4 and SiH4 , respectively, in order to obtain a desired composition ratio worsens the control of boron concentration influencing a film-forming rate and deteriorates the characteristics of a semiconductor device using the film. SOLUTION: This method for producing the film of a silicon-germanium mixed crystal comprises preliminarily determining the relation of the Ge composition ratio of the SiGe mixed crystal with the partial pressure ratio of a hydrogenated Si-containing gas (e.g. SiH4 ) to a hydrogenated Ge-containing gas (e.g. GeH4 ), controlling the partial pressure of a hydrogenated Si-containing gas and the partial pressure of a hydrogenated Ge-containing gas on the preliminarily obtained relation so as to give a desired Ge composition ratio and further give a desired, rate for producing the film of the SiGe mixed crystal, and producing the film of the SiGe mixed crystal by a chemical gas phase growth method using the hydrogenated Si-containing gas and the hydrogenated Ge-containing gas as raw material gases.

Title: Memory having vertical floating gate transistor
Inventor: STUART AQUARISTER BURNS JR
IPC: H01L27/115
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a high-density mounted array of a vertical semiconductor device and a method of forming the array. SOLUTION: This array has the column of bit lines 220 and the row of word lines 225. The gates of transistors function as the word lines and source regions 215 or drain regions 240 function as the bit lines. Arrays are formed between the source and drain regions, and have also vertical pillars 230 which function as channels. The source regions 215 are formed in a self-alignment system and are positioned under the pillars. The regions 215 under the adjacent bit lines are separated from each other without increasing a cell size and the smallest area of cells can be maintained. As the source regions are separated from each other, even if the cells are formed into either of a volatile memory cell constitution and a nonvolatile memory cell constitution, the individual cells are addressed by directly tunneling and can be written.

Title: Discrete cosine conversion circuit and discrete cosine inverse transformation circuit
Inventor: NAKAJIMA HIROYUKI
IPC: G06F17/14
Filed: 1992-01-20
Abstract: PURPOSE:To obtain an exclusive hardware with high efficiency and with the use of a high speed arithmetic algorithm of the discrete cosine transformation which codes the images with high efficiency. CONSTITUTION:The butterfly arithmetic circuits 7-10, the multiplication circuits 11 and 12, and the butterfly arithmetic circuits 13-17 are connected together in the form of pipelines of four stages. In such constitution, a high speed arithmetic circuit 1 is obtained against eight samples. When these pipelines are set in parallel to each other and in four stages in the direction where the processing flow is not cut, the flow is divided so as to turn two circuits 11 and 12 into one. Meanwhile the flow of the circuit 1 is decided by the discrete cosine transformation and its inverse transformation with the use of the switching circuits 3-6. Thus a discrete cosine transformation circuit and its inverse transformation circuit is obtained just with the change of circuit connection caused by the common hardware at a signal point and also obtained with four multiplication circuits when the pipelines are set in parallel with each other and in four stages. In such constitution, the hardware quantity can be extremely reduced.

Title: Horizontal deflection circuit
Inventor: KASHIWAGI SHIGERU
IPC: H04N3/16
Filed: 1987-01-17
Abstract: PURPOSE:To prevent the fall of a reliability, caused by the sudden increase of the loss of a horizontal deflecting transistor (TR) by always keeping the flowing duration of a reverse collector current and the flowing duration of a damper current at an equal value. CONSTITUTION:When the storage time ts1 of the TR 3 is increased by a temper ature rise, etc., the movement of the decrease of the reverse collector current duration (tc) and of the increase of the damper current duration (td) trends to drift in a direction that a voltage level Etc moves toward the negative direc tion (level-E direction) and the voltage level Etd moves toward the positive direction (level +E direction). However, when the Etc begins to become more positive than the Etd, the level of the output voltage E0 of an operation incre ment 22 goes down, and because a pulse width modulation circuit 13 acts toward the direction to reduce the pulse width t0sc of a pulse V0sc, T0 does not approach to T2 but approaches to T1, and finally the position of the T0 does not change. Thus, when a potential difference is ready to arise between the Etc and the Etd, an action to pull back it exists, and therefore the Etc and the Etd are always the same value. Namely, they are not influenced by the dispersion and the drift of a circuit element, etc.
