Title: Current shut-off circuit
Inventor: TAKANO TOMOMASA
IPC: H02H3/087
Filed: 1992-04-28
Abstract: PURPOSE:To use a regulator having a current limiter value larger than a current value set by setting the limit current value in conformity with rating. CONSTITUTION:When a current larger than a limit current value flows, a voltage drop generated in a resistor R3 reaches a specified value or more, and a transistor Q1 is turned on. When a resistor R4 actually serves as a resistor in parallel with a resistor R1 because of the conduction of the transistor Q1 and the output voltage of a regulator 1a lowers, the transistor Q2 of a shut-off circuit section 3 is turned on, and 12V at a point B is divided and applied at the point C of the regulator 1a. When voltage of 1.5V-3.0V is applied to a pin at the point C of the regulator 1a, the ON-OFF limit of the shut-off circuit section 3 acts, and an output from the regulator 1a is turned off.

Title: Rotary drum device
Inventor: MAEDA TADASHI
IPC: G11B5/588
Filed: 1988-06-02
Abstract: PURPOSE:To facilitate the positioning of a plate spring, to improve the accuracy of the sticking position of a head and to shorten a work time by providing a linear part for positioning to the jig in the outer-most circumference of a plate spring to fit the head. CONSTITUTION:A plate spring 41 of a non-magnetic substance to fit a head 5 at the tip is a circular or approximately circular spring in which one or plural approximately concentric non-continuous grooves to the cylindrical coil or the coil bobbin held at the inner-most circumference are provided and a part of the outer circumference or approximately the whole circumference of it are held at the fixed member. By flowing a current at the coil, the head 5 is displaced in the width direction of the tape. When the head 5 is fitted at the plate spring 41, a jig 60 is used so that the plate spring 41 cannot be rotated. Since three linear parts are provided along the linear part of the jig 60 at the outer-most circumference of the plate spring 41, the accuracy of the sticking position at the time of sticking the head 5 to the plate spring 41 is improved and the work time can be shortened.

Title: Casting material for precision casting and production thereof
Inventor: KOGA HIROTAKA
IPC: B22C1/00
Filed: 1978-11-07
Abstract: PURPOSE: To form the texture in which ZrO 2  exists evenly in SiO 2  and provide a low rate of expansion and high heat resistance by limiting the main components of SiO 2 -ZrO 2 -base refractories.  
     CONSTITUTION: SiO 2  and ZrO 2  of high purity are used as raw materials. These are carefully compounded and ground with consideration being paid for the specific gravity differences so that the total amount of SiO 2  and ZrO 2  becomes 97% or more based on weight and that the ratios of SiO 2 /ZrO 2  become 2W20 based on weight. Next, this is put in a melting furnace and is melted at 1800°C or more to the texture wherein zirconia (ZrO 2 ) exists evenly as far as possible in the materix of molten silicic acid (SiO 2 ). Next, this is cooled to solidify, after which it is spherized or powdered. The reasons for limiting the components and temperature lie in that, if the total amount is below the limited one, cracking is liable to occur at the time of pouring of molten metal after the material has been made to a mold. At up to 2 of the ratios, the rate of expansion increases and above 20, heat resistance decreases. At the temperature up to 1800°C, reaction does not take place sufficiently and the intended casting material is not obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a cellulosic fiber product having excellent shape stability and excellent dyeability. SOLUTION: This method for treating a cellulosic fiber product comprises treating the cellulosic fiber product in a steam atmosphere having an absolute pressure >=4 kgf/cm<2> and a temperature of >=140 deg.C for a prescribed time and subsequently imparting water to the cellulosic fiber product in the state maintaining the treating atmosphere. Concretely, the method for treating the cellulosic fiber product comprises fixing the cellulosic fiber product-having pin frame to an upper press plate disposed in a steamer, treating the cellulosic fiber product with steam, downward lowering the upper press plate to dip the upper press plate in water in a vat loaded on a lower press plate and allow the cellulose fibers to absorb the water, and subsequently returning the steam atmosphere to the atmosphere. The cellulosic fiber product having excellent shape stability can thereby be obtained.  The cellulosic fiber product can subsequently be dyed in an intermediate concentration by a conventional known method, and exhibits good dyeability.
