Patent JP-H0756644-A (JP)
Title: Temperature controller
Inventor: NOMURA YASUHISA
IPC: H05B3/00
Filed: 1993-08-11
Abstract: PURPOSE:To detect a phase difference without receiving any influence of the high frequency superposed on an AC power supply and to control the heater temperature with high accuracy by dividing the voltage of the AC power supply by a resistor and a capacitor which are connected in series to the power supply and detecting the phase difference of a temperature measuring element by means of the divided voltage. CONSTITUTION:The high frequency superposed on an AC power supply 1 is eliminated by a resistor R and a capacitor C1 connected in series to the supply 1. The both-end voltage of the capacitor C1 where the power voltage is divided is further divided by two resistors R1 and R2. One of both divided voltage is applied to a temperature measuring element 10, and the other divided voltage is applied between the collector and the emitter of a transistor TR Q1. A base current flows to the TR Q1 when a positive half-wave current flows through the element 10. Then the divided voltage of the supply 1 is applied to the collector of the TR Q1 when a negative half-wave current is applied to the element 10. Thus the time width equivalent to the phase difference corresponding to the temperature of the element 10 is acquired at the collector side of the TR Q1 in each cycle of the supply 1 regardless of the size of the heat- sensitive layer of the element 10.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/716
Filed: 1984-11-05
Abstract: PURPOSE:To improve S/N and durability by disposing magnetic recording layers of the two-layered structure grown approximately axis-symmetrically with the normal erected on a substrate having very small projections. CONSTITUTION:Pulverous crystal particles 11 constituting the 1st magnetic layer and pulverous crystal particles 12 constituting the 2nd magnetic layer are formed on the substrate 8 having the pulverous particles 9. The crystals of the particles 11, 12 grow axis-symmetrically with respect to the normal erected on the substrate surface. The size of the particles viwed from the top surface is therefore smaller than the particles grown without being divided and the nonuniformity arising from the initiation of the growth from the tangential direction is averaged by the division. The very small projections are thereby made uniform and the particles are made smaller and therefore the uniformity of magnetization is increased, by which the S/N and durability are improved.

Title: Foundation cloth for conveyor belt
Inventor: AZUMA HIDEKI
IPC: B65G15/34
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To display excellent adhesiveness with rubber, even if adhering amount of an adhesive agent composition is reduced, by adding the adhesive agent composition added with a silicic anhydride colloidal solution to woven fabric made of fiber for reinforcing rubber. SOLUTION: Stability of viscosity of an adhesive agent composition solution is improved and an adhesive matrix component can be evenly adhered to a surface of fiber by using the silicic anhydride colloidal solution existing in a colloidal state with a particle size of about 50 μm or below and containing silicon dioxide particles and sodium oxide as pH regulating agent by adding the solution to an adhesive agent composition. This is due to formation of hydrogen bonding of a matrix effective component of the adhesive agent composition with a polar group of a rubber material through silicon dioxide formed on the surface of fiber. Therefore, excellent adhesive property with rubber can be displayed, even if amount of the adhesive is reduced as compared with conventional amount, by uniformly adhering the adhesive agent composition to the fiber.

This element is an information giving means, and the circuit constant with which the highest performance is is obtained is stored in this element for each of individual heads. The element 6 sends information of a write current value, by which the data head designated by the circuit 3 displays the highest characteristic, to a write current control circuit 5. The circuit 5 writes or reads data with the current value most suitable for the head based on information from the element 6 by the optimized current control means. Thus, the ununiform head characteristic is not suitably corrected because of correction for each of individual heads.
