Title: Apparatus for optically measuring displacement
Inventor: TAKEMORI TAMIKI
IPC: G01P3/80
Filed: 1991-08-12
Abstract: PURPOSE:To obtain an optical displacement measuring apparatus which can measure the relative displacement and speed of an object in a short time, and the change of the speed of the object at fine time intervals, and improve the measuring accuracy and dynamic range. CONSTITUTION:A speckle pattern of a moving body 19 as a to-be-measured object is recorded double to a first optical modulator 6 with a time interval DELTAt. After the recorded pattern is read, Fourier-transformed and recorded to a second optical modulator 11, the pattern is again processed through a Fourier transformation, whereby a self-correlated signal light is formed on a PSD 15A. The PSD 15A directly detects the peak position of the self-correlated signal light. An operating/controlling device 15B operates the moving amount and speed of the moving body on the basis of the detecting result. At the same time, the operating/controlling device 15B controls the time interval DELTAt for double writing of the speckle pattern based on the operating result so that the self-correlated signal light is detected at the photodetecting surface of the PSD within a small range of measuring errors at all times.

Title: Method for controlling registration of position
Inventor: MINAGAWA FUMIHIKO
IPC: H04W68/02
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to register the position of a mobile station in the case of changing the constitution of a position registering area by instructing all radio base stations corresponding to all zone codes obtained by an inspection step to transmit incoming calls. SOLUTION: A data base 1 recognizes a radio zone registering the position of a mobile station 33 generating an incoming call and position registration receiving time from a position registration receiving table, recognizes the constitution of a position registration area including the recognized radio zone and its position code from a position registration area constitution table, inspects radio zones having the common position code, and reports the inspected result to a control station 2. The control station 2 instructs all radio base stations 12 to 14 in the radio zones reported from the data base 1 to respectively transmit incoming call signals. All the instructed radio base stations 12 to 14 transmit incoming call signals and the incoming call signal transmitted from the base station 12 is received by the mobile station 33.

Title: Lateral trench mos fet having high withstanding voltage and its manufacture
Inventor: KITAMURA AKIO
IPC: H01L29/06
Filed: 1994-09-21
Abstract: PURPOSE: To improve the trade off characteristic of the withstanding voltage - on-resistance of a lateral trench MOS FET. CONSTITUTION: In an n-type drain drift region 4 of a lateral MOS FET, a trench 3 is bored from its surface, and thereby, its drain-drift length is secured, and further, its withstanding voltage is increased. Also, at the end of the n-type drain drift region 4 which is present on the side of its n-type source region 9, its current path is not narrowed in its on-time, and thereby, its on-resistance can be made small. Further, the n-type drain drift region 4 can be contracted while its drain drift length is left intact. Therefore, its chip size can be made small in comparison with lateral DMOS FETs belonging to the class of the same withstanding voltage as it, and thereby, the density of its integration is made high. When the trench 3 is filled with an insulation film 5 or a semi- insulation film, its withstanding voltage can be more increased.  The extending of its gate electrode 7 to the upside of the trench 3 is effective for the increase of its withstanding voltage too.

Title: Magnetic head and its production
Inventor: IIZUKA MASAHIRO
IPC: G11B5/255
Filed: 1993-08-19
Abstract: PURPOSE:To improve the wear resistant strength of the magnetic recording medium-facing surfaces of the magnetic head, of which the recording medium- facing surfaces are formed of a polycrystalline magnetic material and to form these recording medium-facing surfaces to adequate surface roughness. CONSTITUTION:This magnetic head H comes into contact with the surface of a hard disk while this disk is held stopped. The magnetic head floats from the disk when the disk rotates. The crystal faces of a Miller index (110) having the high wear resistant strength of individual crystal grains C1, C2,... are deposited by the rail surfaces 11a, 11b of a slider 11 formed of the polycrystalline material of an Mn-Zn ferrite system of such magnetic head H. The wear resistant strength of the rail surfaces 11a, 11b is, therefore, enhanced and the adequate surface roughness is generated by the rail surface 11a, 11b by which the true contact area with the stopped disk is made adequate. An increase in the starting torque of the disk is thereby prevented.

Title: Production of iron-zinc alloy plated steel sheet
Inventor: SAKAGUCHI SHIRO
IPC: C25D7/06
Filed: 1986-09-29
Abstract: PURPOSE:To maintain the grade of a product in spite of a change in the compsn. of an alloy or the amount of plating stuck by lowering current density in synchronization with a reduction in the passing speed of a steel sheet, making the lowered current density constant and further reducing the passing speed of the steel sheet. CONSTITUTION:In a first stage, current density is gradually lowered in synchronization with a reduction in the passing speed of a steel sheet within a range in which the compsn. of an alloy is changed within permitted limit with respect to quality control. Before the change exceeds the permitted limit, the lowered current density is made constant in a second stage and only the passing speed is further reduced. The change in the compsn. of the alloy due to the lowering of the current density is kept within the permitted limit. An increase in the amount of plating stuck due to the reduction in the passing speed is restricted by reducing the passing speed within a range in which the amount is increased within permitted limit with respect to quality control.
