Title: Digital phase control system
Inventor: NAKAMURA FUMIHISA
IPC: H02P5/52
Filed: 1985-05-13
Abstract: PURPOSE:To make unnecessary the digital monomulti function by resetting the phase discriminator for the second input signal by the prescribed timing to the initial value at the time of the action in which the deviation of the phase discriminator for the first input signal comes to be zero in the consecutive recording video recording mode. CONSTITUTION:The presetting timing of a capstan phase comparing counter 22 is formed from a cylinder phase comparing system NHY gate 8. At such a time, presetting is selected so that the timing of the phase locked value of the counter 22 may come to the fall timing of an external vertical synchronizing signal VSY 1. Thus, a control pulse signal CTL is not delayed by the digital monomulti function as conventionally, and the deviation can be latched by the CTL itself. Consequently, it is not necessary to use the digital monomulti function.

Title: Biosensor
Inventor: YUGAWA KEIKO
IPC: G01N27/327
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive biosensor of high shelf stability in which activity of an enzyme is exerted to a maximum, by setting a water soluble salt of a divalent metal in a reaction layer or separately from a reaction layer in the vicinity of the reaction layer. SOLUTION: A reaction layer 7 including an enzyme and an electronic mediator is formed on an electrically insulating substrate 1 having an electrode system. A water soluble salt 10 of a divalent metal is held between the reaction layer 7 and an opening part 12 of a sample feed path separately from the reaction layer 7. When a sample solution such as blood or the like is added to the sensor, the sample solution dissolving the metallic salt is introduced to the reaction layer 7 and, the dissolved metallic salt is dissociated, thereby generating ions of the divalent metal. The metallic ions are taken into the enzyme where metallic ions are detached through purification or preservation for a long time. As a result, a steric structure of the enzyme is reconstructed, or activity is recovered.  Since activity of the enzyme included in the reaction layer 7 is thus promoted, a quantity of the enzyme to be held in the sensor can be minimum and the sensor becomes inexpensive.

Abstract: PURPOSE:To completely fill a recess of the uneven surface with insulating films for isolating elements and to prevent a wiring layer or the like from being disconnected, by depositing an insulating film having a thickness of less than a half of the width of the recess by CVD and then forming another insulating film by bias spattering method. CONSTITUTION:A silicon dioxide film 2 is formed on a P type silicon substrate 1 as a mask which is resistive to etching and ion implantation, and recesses 3 are provided in the field regions by RIE. Ions of B<+> are subsequently implanted therein to form a P<+> layers 4. After removing the thermal oxidation film 2, a silicon dioxide film 5 is deposited on the whole surface of the substrate. A silicon dioxide film 6 is then formed by the RF bias spattering, and a film of positive resist 7 having high thermal flow properties and containing ethyl cellosolve acetate as the main component is applied thereon. The resist film 7 and the silicon dioxide films 5 and 6 are etched at the same etching rate so that the silicon dioxide films 5 and 6 are filled in the recesses to form element isolation regions. Since these regions have a two-layer structure, the substrate is effectively prevented from being affected by the bias spattering and therefore the reliability of the element characteristics is improved.

Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a magnetic recording medium by applying a lubricant contg. higher fatty acid having carbon atoms of a specific range on a hard carbon (DLC) film, by which its characteristics are sufficiently exhibited. SOLUTION: A magnetic metallic thin film is formed on a nonmagnetic base and further, the carbon protective film is formed thereon. The lubricant contg. at least 14 to 26C higher fatty acid (constitutional formula: Cn H2n+1 - COOH) is applied on the carbon protective film. If the carbon atoms of such higher fatty acid are below 14, the effect as the lubricant is weak and if the carbon atoms are larger than 26, the solubility in a solvent degrades and the coating application is difficult and, therefore, the carbon atoms are preferably 14 to 26. The lubricant is sufficiently functioned, the sufficient durability is assured and high reliability is obtd. if the recording medium is constituted in the manner described above.

Abstract: PURPOSE:To prevent the medium from being damaged at the edge, by holding the magnetic core assembly with the attitude in parallel with the medium, through the connection of the tip of support spring and the magnetic core assembly with torsional spring. CONSTITUTION:The support spring 3 and the magnetic core assembly 1 are linked with the torsional spring 10. The plate spring 6 and the pressure arm 5 are placed between the springs 3, 3. With this constitution, when the assembly 1 is detached from the medium, the spring 3 is bent and the assembly 1 and the head holder 11 make an angle B. Further, at the extension part 9, the inverse torsional angle D is produced as B with the opposite moment of the spring 10. Accordingly, the tilt angle at the tip of the spring 3 is the angle E which is the subtraction of the operating angle A of the holder 11 and the opposite torsional angle D from the angle B. Thus, the setting of the characteristics of the spring 10 to compensate the angle E can make parallel the attitude of the assembly 1 in parallel with the medium 1, allowing to prevent the medium from being damaged at the edge.
