Title: Filter circuit
Inventor: ODATE KAZUYUKI
IPC: H03H11/04
Filed: 1992-01-17
Abstract: PURPOSE:To decrease a delay time in the state of an input signal by providing a switching means able to short-circuit a resistor in response to a voltage across a resistor depending on a change in an input signal to the circuit. CONSTITUTION:When a fluctuation of an input signal from an input terminal 21 increases at a certain speed or over and a voltage across a resistor 23 exceeds a base-emitter voltage of a transistor(TR) 25, the TR 25 is turned on. Since the resistor 23 is short-circuited, the time constant is reduced and the delay time is reduced similarly to the case with an increased pass band and the input signal passes through the circuit while the pass band is increased. Moreover, when a fluctuation of the input signal decreases at a certain speed or over and a voltage across a resistor 23 exceeds a base-emitter voltage of a TR 26, the TR 26 is turned on. Since the resistor 23 is short-circuited, the time constant is reduced and the delay time is reduced similarly to the case with an increased pass band and the input signal passes through the circuit while the pass band is increased.

Abstract: PURPOSE:To prevent a conveyor belt from shifting laterally or longitudinally and to eliminate the transfer shift of a color image by fixing a filmy reinforcing material to the belt base cloth of a transfer material conveyor belt and also fixing a guide rib corresponding to the reinforcing member, and giving the conveyor belt rigidity. CONSTITUTION:The conveyor belt 100 is formed by fixing the reinforcing material film sheet 100B to one end part of belt base cloth 100A made of screen meshes and further fixing the guide rib 10C thereupon. The fixation positions of the reinforcing material film sheet 100B and guide rib 100C to the belt base cloth 100A are not positions where the transfer material of the belt base cloth 100A is conveyed and correspond to guide grooves 11b-14b and 104b of rollers 11-14 and a backup roller 104. Thus, the guide rib 100C is fixed to the reinforcing material film sheet 100B which has rigidity and high tensile strength while facing the respective guide grooves, so the rib faces a thrust force operating on the conveyor belt 100 and maintains perpendicularity, so that the conveyor belt 100 is prevented from being shifted laterally or longitudinally.

Title: Magnetoresistive effect element and magnetic sensor
Inventor: ODAGIRI MITSURU
IPC: G01R33/09
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To improve heat resistivity and environment resistance of a magnetoresitive effect element having a laminated structure of magnetic and non-magnetic layers. SOLUTION: Diffusion preventing layers 4, 6 of Ag are provided between a non-magnetic layer 5 of Cu and magnetic layer 3, 7. The non-magnetic layer 5 is a multi-layer film formed of a thin Cu film and a thin Ag film. Aggregation due to heat treatment does not take place because the thin Ag film is in close contact with the Cu layer. Moreover, Ag makes a good diffusion preventing layer. A large magnetoresistive effect is obtained because Cu is used for the non-magnetic layer 5, and heat resistance is improved because the Ag layer is included. Further, corrosion resistance is improved by providing a corrosion resistive thin metal film between the layers of the multi-layer film.

Title: Device and method for removing moisture in liquid crystal
Inventor: KINUGASA NAOKI
IPC: C09K19/00
Filed: 1985-01-21
Abstract: PURPOSE:To make possible the removal of the moisture diffused in a liquid crystal by providing a filter in a liquid crystal passage to increase the surface area of the liquid crystal supplied into a vacuum chamber and providing a liquid crystal receiver for collecting the liquid crystal. CONSTITUTION:The surface area of the liquid crystal 16 is increased by the filter 17 and such liquid crystal is supplied into the vacuum chamber 11 when the liquid crystal 16 is supplied from the open end on the upper side of the liquid crystal passage 14 to the liquid crystal passage 14. The gaseous pressure in the vacuum chamber 11 is higher than the vapor pressure of the liquid crystal and therefore the liquid crystal does not evaporate but the vapor pressure of water is higher than the gaseous pressure in the vacuum chamber 11 and therefore the moisture in the liquid crystal evaporates. The vapor is drawn into a vacuum pump 13 and is released to the outside. The liquid crystal is contained in the liquid crystal receiver 18. The difference in the vapor pressure between the liquid crystal and water is utilized and the surface area of the liquid crystal can be increased by the filter. The efficient removal of the trace moisture in the liquid crystal in a relatively short period is thus made possible and impurities such as dust contained in the liquid crystal are removed as well.
