Title: Method for modifying glass fiber
Inventor: ARAI TAKAYOSHI
IPC: C03C25/00
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To improve the water repellency of glass fiber by treating the glass fiber under a condition of equal to or above a specific temp. and equal to or above a specific humidity. SOLUTION: The glass fiber is treated at >=60 deg.C and >=55% RH. The treating temp. is preferably 80-150 deg.C and the humidity is suitably >=80% RH. The treating time is different with the temp. and the humidity and is fixed by previous testing. The treating time lasts usually a whole day and night. The treatment is performed by leaving the glass fiber in a room kept at a high temp. and high humidity. After the treatment, the glass fiber is taken out of the room, washed and then used. A water repellent agent is unnecessary for the glass fiber because the water adsorption property is decreased without deteriorating the air permeability even if the glass fiber is heated and humidified. Any kinds of short fiber and long fiber are applicable as the glass fiber.  The glass fiber is widely utilized, e.g. as a heat insulating material, a sound proof material, an electrical insulating material, FRP, a filter and the like by giving water repellency in addition to the air permeability, the heat insulating property, the heat resistance or the like.

Title: Manufacture of rare earth element permanent magnet
Inventor: ISHIBASHI TOSHIYUKI
IPC: H01F1/04
Filed: 1986-03-17
Abstract: PURPOSE:To improve the yield of manufacturing a rare earth element permanent magnet and to stabilize the quality of the magnet by magnetizing an iron-boron alloy in which the macro structure of an ingot at casting time is columnar to simplify the steps. CONSTITUTION:An alloy made of rare earth element, iron and boron in a basic structure having a columnar structure B in a macro structure of an ingot at casting time is magnetized. When a melted metal is cast from a crucible in a mold, the metal is first contacted with the wall of the mold, quickly cooled to a degree where a large number of nuclide are generated to form a chill layer A, heat is then fed to the mold, and the columnar structure B is extended perpendicularly to the wall of the mold toward the interior. When flow of the heat is further eliminated, an equi-axed structure C is presented instead of the structure B, and the metal in the mold is completely solidified. Thus, the pulverizing property is improved to largely shorten the time required for pulverizing step to remarkably improve the magnetic performance of a permanent magnet thus obtained, thereby improving the mass productivity and the stability of the quality.

Title: Temperature compensating circuit for weighing equipment
Inventor: NAITO KAZUFUMI
IPC: G01G3/18
Filed: 1989-03-09
Abstract: PURPOSE:To perform the temperature compensation with high precision in a wide temperature range by allowing the temperature coefficient of the output of an amplifying circuit to act to cancel positive/negative secondary coefficients and cancelling an excess compensation component. CONSTITUTION:The change of the output signal for the change of temperature of a bridge circuit 1 including a distorting body is preliminarily measured to examine the temperature-output characteristic of the bridge output, and the temperature coefficient is obtained by this characteristic. When the temperature coefficient of the bridge output is determined, the temperature coefficient of the output of a high-input differential amplifying circuit consisting of operational amplifiers 6 and 7 and a differential amplifying circuit 14 is obtained, and respective resistance values of a thermosensitive resistance element 10 and a precise resistance 12 made of combination of copper, nickel, etc., are so combined that the output of this circuit is approximately flat. These resistance values are determined; and then, since the positive secondary temperature change component of the signal outputted from the circuit 1 is cancelled by the negative secondary temperature change component of its own high-input differential amplifying circuit, a signal proportional to only the weight is outputted independently of the change of temperature in a wide temperature range.

Abstract: PURPOSE: To make possible necessary operations such as opening and closing operations of valves of exhaust sequence and controlling of applied voltage of an electron gun by providing a tertiary coil for generation of low voltage to a transformer for ion pump power source.

Title: Differential amplifier
Inventor: ASAKAWA TATSUJI
IPC: H03F3/45
Filed: 1989-03-10
Abstract: PURPOSE:To reduce the dependency upon the supply voltage of the electric characteristic of the whole circuit by generating a bias voltage based on the voltage which is real-number times as high as the differential voltage of a differential amplifier which generates the difference voltage between threshold voltages different from each other. CONSTITUTION:A pair of transistors TRs 34 and 35 having the same polarity are different in threshold voltage, and the TR 35 is a depletion type TR and has the gate connected to a potential VSS, and the gate of the TR 34 whose threshold voltage is higher than that of the TR 35 is connected to the output, and therefore, a threshold voltage difference is generated in the output, and a TR 40 which has the same polarity as a constant current source TR in a differential amplifying stage and has the gate and the drain connected in common and has a high conductance coefficient is connected in series to the output. Consequently, when a current is supplied from a TR 38, a voltage Vg which is the sum of the difference voltage between different threshold voltages of TRs 34 and 35 having the same polarity and the threshold voltage of the TR 40 is generated in the drain of the TR 40 and is applied to the gate of the constant current source TR. Thus, the dependency upon the supply voltage of the electric characteristic of the circuit is reduced.
