IPC: G03G15/04
Filed: 1987-05-21
Abstract: PURPOSE:To prevent noise generation and to improve S/N by using a non- reflecting member which does not reflect the light transmitted through an object to be read toward the object to be read to constitute the surface of a body for pressing object to be read, which surface comes into contact with the object to be read.

Title: Mehtod for controlling travel of magnetic tape
Inventor: ONO YUKITAKA
IPC: G11B15/43
Filed: 1985-06-07
Abstract: PURPOSE:To remove securely the loose winding of the inner periphery of a supply reel by rewinding a magnetic tape at the 2nd position after it is provisionally traveled at the 1st position in a normal direction. CONSTITUTION:The magnetic tape 1 is accelerated up to a certain speed, and then is decelerated during a certain period. During the deceleration, the tensile strength of the tape is detected 11, and the speed is detected 8. When the tensile strength is abnormal, an NG signal is issued. When the number of times of NG signal output signal output signals is below the prescribed one, motors 7 and 10 are controlled and driven 12, 9 and reels 2 and 6 are appropriately accelerated and decelerated. When said number exceeds the prescribed one, the tape 1 is gradually accelerated in the normal direction, continuously traveled up to a tailing marker at a high speed, then continuously traveled in a reverse direction to rewind. During the continuous traveling, activation is not stopped, and therefore there are no loose winding and slip on the way to keep the tensile strength fluctuation within a normal range. Accordingly the tap e1 is rewound to the supply reel 2 by an appropriate tensile strength due to a rewinding travel from the tailing marker, thereby removing the lose winding.k.

Title: Feeder unit in wire electric discahrge machine
Inventor: FUTAMURA SHOJI
IPC: B23H7/10
Filed: 1986-05-28
Abstract: PURPOSE:To make erosion rate and machining accuracy improvable, by making a wire electrode travel in the low-melting point metal energized so as to supply power to this electrode, while making an energizing area of the wire electrode larger, and preventing it from being deformed by external force. CONSTITUTION:A fluid low-melting point metal 4 is forcedly fed to a feeder vessel 3 so as to cause it to be reached to the specified level by a piston 7 via an innerconnecting pipe 8, and a discharge current is fed to a feeding electrode 5 being set up inside the feeder vessel 3 by an electric power unit. Therefore, feeding to a wire electrode 2 traveling through the feeder vessel 3 is carried out via the low-melting point metal 4, and in order to make a contact area between the wire electrode 2 and the low-melting point metal 4 larger in view of performing effective feeding, a level of the low-melting point metal 4 is maintained as high as possible. Accordingly, the piston 7 of a cylinder 6 is moved up and down and thereby level adjsutments for the low-melting point metal 4 can be done freely. Thus, current-energization is effectively perfowmable, while any deformation in the wire electrode due to external force is prevented from occurring and, what is more, erosion rate and accuracy both are improvable.

Abstract: PURPOSE:To prevent simultaneous turn-on state of PMOS and NMOS by providing a control circuit section suppressing a through-current to a gate electrode input signal generating section of final stage PMOS and NMOS. CONSTITUTION:When an internal signal propagated through an internal signal electrode 7 changes from a ground level L to a power level H, an output signal of a 2-input NOR 9 and inverters 12, 13 changes respectively from H to L, L to H and H to L, and an EMOS (N channel MOS field effect TR) 4 changes from the turn-on into turn off. On the other hand, an output signal of the 2-input NAND 8 changes from H to L after the output signal of the inverter 12 changes to H and a PMQS (P channel MOS field effect TR) 3 changes from turn-off into turn-on after an output signal change (from H to L) of the 2-input NAND 8 is caused. Thus, simultaneous turn-on state of the PMOS 3 and NMOS 4 is evaded.

Abstract: PURPOSE: For an effective, small head loss treatment of aqueous solution, filter membrane layer of cation and anion exchange fibers formed on a supporter is used to pass the aqueous solution to remove ions and the like, and used filter membrane layer is separated by using air and water.  
     CONSTITUTION: A precoat system including a filter bath 1, a precoat bath 7 and a precoat pump 8 is filled with water. An adequate amount of cation and anion exchange fibers each having diameters of 2W200μ and length of twice the diameter is stepwisely added into the precoat bath 7 and mixed by stirring to allow fibers to be mutually entangled to form slurry.
