Title: Method for deoxidation
Inventor: TAYA SHIRO
IPC: C02F1/58
Filed: 1992-07-23
Abstract: PURPOSE:To remove dissolved oxygen in water to be treated at low temp., safely, easily and inexpensively by providing catalytic activity to a metal ingredient at a temp. lower than a specified temp. in a method for deoxidation from water which is brought into contact with a catalyst carrying the metal ingredient. CONSTITUTION:In a method for deoxidation of water wherein a hydrogen donor is incorporated in water contg. dissolved oxygen (DO) and the water is brought into contact with a catalyst carrying a metal ingredient, it is constituted in such a way that the metal ingredient has a catalytic activity at a lower temp. lower than 100 deg.C. This method can be executed e.g. by incorporating a specified amt. of a hydrogen donor such as methanol in the water contg. DO and passing this through a fixed bed type reaction tank filled with a carrying catalyst. The reaction condition is in such a way that the reaction temp. is lower than 100 deg.C and the pressure is a pressure where the water to be treated can be kept under liq. phase. As the reaction temp. increases, the ratio of removal of Do increases and retention time of the water in a reaction tower becomes short, but the cost of installation increases. In addition, the pressure at reaction time may be a pressure being enough to keep the liq. phase at most at a specified temp.

Title: External character editing device
Inventor: NAKAJIMA MISAKI
IPC: G09G5/24
Filed: 1993-08-09
Abstract: PURPOSE:To facilitate corrections for balancing characters and make the corrections accurate by adding a function which counts dots on an external character screen. CONSTITUTION:In an external editing function, the means which counts the longitudinal or lateral dots of an edited character is provided and when a place where the dots are counted is specified, the number of dots while white bits succeed when the place is a white bit or dots while black bits succeed when the place is a black bit is counted and displayed. For example, when a longitudinal ruler function 33 is selected with a palette 32 at the time of the selection of the editing function on an external character editing screen 31, it is necessary to measure the number of the dots at the blank part between lines. For the purpose, a mouse is clicked at a desired measurement position, and then an arrow 34 indicates the measurement section and the number of dots is displayed by it. Consequently, when an external character is generated or corrected, the time required to count dots can be shortened and the number of dots is prevented from being mismeasured.

IPC: H01H73/02
Filed: 1987-08-10
Abstract: PURPOSE:To make a current interruptible in a way of opening a contact when an overcurrent has flowed thereinto by installing a trip mechanism for opening a switching mechanism at the time of the overcurrent flowing. CONSTITUTION:When a short circuit occurs in a main circuit and an overcurrent flows into the load circuit, this overcurrent flows into a trip coil 41 of a trip mechanism 40, and a driving lever rotates, whereby a U-shaped driving part pushes a main movable contact 24 upward solidly together with a crossbar 25. And, the main movable contact 24 is separated from a main fixed contact 22 at high speed by dint of magnetic resiliency produced in a gap with the fixed contact 22. With this constitution, a short-circuit current flowing in the load circuit comes to be interrupted in consequence by trip action of the trip mechanism 40, so that a breaker and a fuse for short-circuit protection are unnecessary to be separately installed.
