Title: Magnetic recording medium
Inventor: KAZAMA TOSHINORI
IPC: G11B5/708
Filed: 1989-06-23
Abstract: PURPOSE:To form the magnetic powder which is uniform in distribution, with less surface defects, good in electromagnetic conversion characteristics and can assure the strength of a coated film, by forming the shape of fillers incorporated in a magnetic layer to the shape nearly similar to or analogous with the shape of the magnetic powder. CONSTITUTION:The magnetic powder 3 and the fillers 4, 5 flocculate and suspend as several micron particles in a resin soln. 6 when a magnetic coating compd. 1 is spin-coated on a substrate. The magnetic powder 3 is attracted and moved at places near a magnetic pole 7 when the magnetic coating compd. is rotationally oriented in a magnetic field. While the spherical fillers 4 are large in volume and surface area, the fillers hinder the movement of the magnetic powder 3, the acicular fillers 5 have the same shape as the shape of the magnetic powder 3 and are small in volume and surface area. This filler, therefore, facilitates the movement. The degradation in the orientability near the fillers and the generation of flocculation are thus reduced. The force of the above-mentioned pole is, therefore, weakened and the generation of microdefects by the crack, etc., of the coated film is suppressed.

Title: Production of semiconductor wafer
Inventor: KAZAMA MIKIO
IPC: H01L21/22
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To diffuse N-type impurities at a higher concentration within a fixed time in the first diffusion step by employing an oxychloride phosphorus, taking the liquid state under normal temperature as the impurity in a wafer kept at a specific temperature in the first diffusion step and easily gasifying it. SOLUTION: Not only the diffusion layer of a specified depth is satisfied after second diffusion step but also a high surface concentration of 10<20> atoms/cc or is also satisfied. Specification of phosphorus (oxychloride phosphorus) in N-type impurities means a maximum product of solubility and diffusion factor in the working temperature range of 1100-1300 deg.C and thereby basic requirements can be satisfied. Since the impurity source of phosphorus, i.e., oxychloride phosphorus, is in a liquid form under normal temperature, it can be fed easily and continuously at a constant concentration by means of a bubbling unit kept at a constant temperature, along with Ar gas containing 0.5% or more of O2 gas resulting in high concentration diffusion of impurities in the first diffusion step.

Filed: 1982-09-14
Abstract: PURPOSE:To decrease the waveform distortions, by cascading a primary LC type LPF circuit to a circuit part which switches a primary LC type delay equalizing circuit and the primary LC type LPF circuit by means of an external signal with an impedance converting circuit held between those circuits. CONSTITUTION:The reproduced output given from a head 19 is supplied to a peak shift compensating circuit via a differential amplifier 20. When external signals PC-1 and PC-2 are set at level O, the circuits existing before transistors (TR) 29 and 30 is limited only to a primary LC type LPF circuit. This LPF circuit is replaced with a primary LC type delay circuit if the signals PC-1 and PC-2 are set at a high impedance respectively. In the former case, the LPFs are cascaded with TRs 29 and 30 held between and used at the outer circumference side of a disk in a peak shift OFF state. While the LC type delay circuit is used at the inner circumference side of the disk in a compensation ON state. In the former case, if natural frequencies of the front and back stage LPFs are set at f01 and f02 together with damping constants set at K1 and K2 respectively, the relation shown in an equation is satisfied. In such a way, the waveform distortions are decreased for compensation.
