Title: Magnetic disk device and control method for the same
Inventor: ASANO YOSHIAKI
IPC: G11B19/00
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce a fault caused by no seek operation of an HDD(hard disk drive) for a long time in a magnetic disk device where plural HDDs are controlled by one seek control part. SOLUTION: When a seek command to an HDD 3a is received from a host device 1 by the seek control part 2 of the magnetic disk device 4, if a fixed time has not elapsed after processing a main loop, seek control is performed on a specified HDD 3a. Then, if the fixed time has elapsed after processing the main loop, the seek control on the HDD 3a and synchronous seek control on other HDD 3b are performed. By this method, the state of no seek operation for a long time is prevented, and since the occurrence of a fault due to dust accumulated on the surface of a magnetic disk medium can be prevented, an effect of promoting reliability of the magnetic disk device is secured.

Title: Liquid fuel combustion device
Inventor: KAWAKAMI AKIO
IPC: F23D11/06
Filed: 1989-12-27
Abstract: PURPOSE:To facilitate a gasification of liquid fuel even in the event that a gasification cylinder is not heated sufficiently just after stating of combustion and further prevent the not-yet gasified liquid fuel from flowing down out of the gasification cylinder by a method wherein an inner surface of the gasification cylinder is provided with porous material having a heatresistant characteristic or a metallic net. CONSTITUTION:Since a gasification cylinder 16 is not sufficiently heated just after starting combustion, some liquid fuel which can not be gasified within the gasification cylinder 16 under its dispersion of fine partible state with a rotating dispersion member 17, the fluid fuel of not-yet gasified state flows down along the inner walls of the gasification cylinders 16 and 30. Since the circumferential portions 24 and 31 of the gasification cylinders 16 and 30 are provided with porous material 25 or metallic net 32, heat transmitting surfaces of the circumferential sides 24 and 32 of the gasification cylinders 16 and 30 are increased and a contact area between the not-yet gasified liquid fuel and the gasification cylinders 16, 30 is increased, resulting in that the not-yet gasified liquid fuel may easily be gasified. Since the not-yet gasified liquid fuel is held at the irregular portions of the porous material 25 or metallic net 32, the liquid fuel hardly flows out of the gasification cylinders 16 and 30, i.e., into the combustion cylinder 1.

Title: Dry-etching process
Inventor: OMI TADAHIRO
IPC: H01L29/78
Filed: 1989-12-31
Abstract: PURPOSE:To do high anisotropic etching with high selecting at high anisotropy but also a sufficient rate for practical use by a method wherein a first gas containing a halogen gas and nitrogen gas is used for a first plasma etching and a second gas of a pure halogen gas or of a halogen-containing gas is used for a second plasma etching. CONSTITUTION:A protective film against sidewall is formed by a plasma of a gas containing a halogen gas and nitrogen gas to avoid the reaction of radicals of halogen atoms while the etching process of the bottom surface is accelerated by ion assist effect for enabling the surface to take anisotropical shape. Furthermore, the selectivity of masks or underneath oxide film can be enhanced by adding a bit of O2 gas. On the other hand, the surface of Si can be nitrified or oxidized to be insulated by adding N2 and O2 gas. Accordingly, in order to form a contact layer after etching process, the addition of N2 and O2 is stopped immediately before finishing the etching process while the etching process is performed using the plasma of a gas of a pure halogen gas or halogen-containing gas so as to improve the processing quality.

Title: Method and device for measuring saturation point of solution
Inventor: FURANKU BII MESEROORA
IPC: G01N30/88
Filed: 1989-12-28
Abstract: PURPOSE:To obtain the saturation point f a compd. having a limiting solubility in a solvent in a short time by measuring the concn. of of a tracer easy to measure without directly measuring the target compd. CONSTITUTION:A dil. solin. 10 obtained by diluting a soln. to be measured is passed through the packing 30 in a column 28 consisting of a solid soln. of the target compd. and tracer, hence the dil. soln. is saturated with the target compd., and the tracer is also eluted. The dil. soln. flows into a flow cell 32, and the concn. of the tracer in the soln. is measured therein by a spectrophotometer. The saturation point of the target compd. in the undiluted soln. to be measured is determined from the measured value. The kind of the tracer is selected only on the ground that the tracer concn. is easily of accurately measured and further the tracer forms a solid soln. with the target compd. even in a fixed case. Consequently, the relative saturation point of calcium sulfate as the specified component in the soln. is rapidly determined without directly analyzing the calcium sulfate.
