Title: Production of thin-film magnetic head
Inventor: YAMAKAWA KAORU
IPC: G11B5/31
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To improve the magnetic characteristics of a thin-film magnetic head by forming the film of a soft magnetic material in vacuum from a diagonal direction in the state of applying a magnetic field in the prescribed direction of pole parts in forming the film of the lower magnetic pole or upper magnetic pole of the thin film magnetic head. SOLUTION: The uniform magnetic field is applied on a wafer 2 in the transverse direction of a yoke part by a permanent magnet 1. The soft magnetic material released from an evaporating source collides against the wafer 2 from the diagonal direction, thereby forming the plating base of a lower magnetic pole layer 3 or upper magnetic pole layer 4. As a result, axes are eventually aligned to the axis 6 of easy magnetization. A supporting table holding the wafer 2 and the permanent magnet 1 moves while rotating and revolving and the soft magnetic material films are uniformly formed on the wafer 2, by which the plating bases are formed.  The soft magnetic material is brought into collision against the wafer 2 in the state of applying magnetization thereon by the permanent magnet 1 in the direction of the axis of easy magnetization, by which the plating bases are film-formed and anisotropy is more strongly developed. Bs is made larger and Hc smaller, by which a magnetic flux value is improved.

Title: Actuator
Inventor: KOJIMA TADASHI
IPC: F16K31/12
Filed: 1980-12-17
Abstract: PURPOSE: To obtain a constant input-output property by detecting a temperature of working fluid and controlling a drive signal of a solenoid pump according to its temperature, where the fluid pressure obtained at a solenoid pump is utilized to drive valves.  
     CONSTITUTION: A drive circuit 10 of solenoid pump 2 feeds a coil 11 with a specified drive signal when it is given an operation command from outside. An output signal of a temperature detector 21 is used to lower a frequency and (or) a peak value of the drive signal as the detected temperature rises. Accordingly, pressure in a second chamber 4 accurately corresponds to the operation command directed to the drive circuit 10 at all times. Therefore, operation of a responsive body 5 will not be influenced by a fluid temperature (namely viscosity).

Title: Automatic answering telephone set having a remote listening operation
Inventor: HASHIMOTO KAZUO
IPC: G11B31/00
Filed: 1982-10-09
Abstract: PURPOSE:To control easily the relation between a capstan and a pinch roller, by shifting up and down a tape sliding stand with a link mechanism linked to a small sized motor and a gear. CONSTITUTION:When a call signal is incoming to terminals L1, L2, the call signal is detected at a ringing amplifier 1 to hold a relay Y-1 being a load in operative state. Since a loop is formed with a contact y1-1 of the relay Y-1 via a primary winding of a line transformer LT, the call signal stops ringing. When an output of the ringing amplifier 1 is held at an H level at the same time, a transistor (TR)-1 turns on via an inverter G-2 and an NAND gate G-1 in the state where a motor M2 is not driven; then a motor M1 is driven. A response tape is started by the motor M1 and a response message is amplified at an amplifier (not shown because of its conventionality) and transmitted to a telephone line.

Title: Production of carrageenan
Inventor: ITOU HAJIME
IPC: C08B37/00
Filed: 1983-09-27
Abstract: PURPOSE:To produce carrageenan which can exhibit easily and quickly a thickening effect, a gelling property, etc., by washing carrageenan precipitate by adding a hydrophilic organic solvent to a filtered extract of carrageenan with a hydrophilic organic solvent and drying and grinding it. CONSTITUTION:Rhodophyceae (e.g., eucuma cotoni) is hot-extracted in a usual manner and filtered to obtain a clear filtrate. A precipitate is formed by adding a hydrophilic organic solvent (e.g., isopropanol) to the filtrate in such an amount that its concentration is 45-48wt%. The precipitated carrageenan is washed with a hydrophilic organic solvent of a water content of 20wt% or below. By this treatment, the ratio of the hydrophilic organic solvent to water in the carrageenan precipitate is heightened, and the efficiency of making it porous can be heightened. The product is dried at 50-80 deg.C in vacuum, if necessary, and ground so that it can pass through a 100-mesh sieve entirely. By making it porous, its rate of dissolution in cold water is increased markedly, and therefore carrageenan which can exhibit easily a thickening effect, a geling property, etc., can be produced.
