Title: Method for metallizing surface of ceramics
Inventor: SHIRASAKA SHIGENORI
IPC: C04B41/88
Filed: 1987-10-26
Abstract: PURPOSE:To simply obtain a product having an accurate shape by colliding iron particles against the surface of ceramics at ordinary temp. at a specified velocity. CONSTITUTION:Iron particles are collided against the surface of a ceramic piece 1 at ordinary temp. at a high velocity of >=20m/sec. By the collision, the iron particles are pulverized to fine particles of submicron unit, the surface of the piece 1 is finely cracked 2 and a metal part produced by the iron particles enters the cracks 2. A metallizing layer 3 joined to the metal part in the cracks 2 grows on the surface of the piece 1. Since the metal part in the cracks 2 acts as an anchor, the bonding strength of the metallizing layer 3 to the ceramic piece 1 can be increased.

Abstract: PURPOSE:To contrive prevention of a motor or the like from being burned, by causing a controlling part for driving parts for a carriage, paper feed and a printing head to monitor other driving parts so as to detect generation of an abnormal condition, and to stop energization of the driving part in which the abnormal condition is present. CONSTITUTION:When a master CPU 3 outputs a printing command to a slave CPU 6 on the basis of input data from a host computer 1, the CPU 6 outputs operation control signals to driving parts 7-9 for carriage feed, paper feed and printing, based on the command. The slave CPU 6 controls the driving parts 7-9, based on signals from various sensors 10 and switches on a console panel 11. When an abnormal condition in a driving current for each of motors 12-14 for a carriage, paper feed and a printing head is detected by an abnormality detecting part 15, an abnormality detection signal is outputted to the master CPU 3. Upon receiving the abnormality detection signal from the slave CPU 6 or the abnormality detecting part 15, the master CPU 3 outputs a stop signal to each of the driving parts 7-9, thereby cutting off the driving current.

Abstract: PURPOSE:To enlarge a variable range of an oscillation frequency by decreasing the parasitic capacity of a positive feedback path, and enlarging a variation ratio of the variable capacity of an oscillation circuit being parallel to the parasitic capacity like an equivalent circuit. CONSTITUTION:An oscillation output of an oscillation differential amplifier 2 is subjected to positive feedback to a base of a transistor Q2 for forming a differential pair and oscillated through a transistor Q12 of an emitter follower input means 17B. In this case, the parasitic capacity viewed from a resonance circuit 4 becomes equivalent to that which connects the parasitic capacity of Q12 in series to the parasitic capacity of Q3 and Q2 of an amplification stage 3, and becomes that of a small number pF. Accordingly, by forming the parasitic capacity being in parallel to a variable capacitor C3 of the oscillation circuit 4 to an extremely small one and enlarging a variable capacity ratio of C3, a variable range of an oscillation frequency can be enlarged.

Filed: 1987-10-30
Abstract: PURPOSE:To achieve a smaller size of a steam separator and a stem dryer by disposing a moisture remover within a reactor pressure vessel for removing moisture provided in the course of a main steam pipe. CONSTITUTION:A steam separator 8, a steam dryer 9 and a shroud head 10 are housed into a steam separation pressure container 7 provided in the source of a main steam pipe 6. With the miniaturization of the steam separator 8 and the steam dryer 9, the length of a body of equipment combining a reactor pressure vessel 1 and the steam separation pressure container 7 can be shortened to allows the lowering of the height of the reactor containment vessel. Even if the steam separator 8 and the steam dryer 9 should cause a trouble, a core 2 is not affected at all as they are separated from the core 2. Moreover, this eliminates any construction at an upper portion of the core 2, thereby permitting the setting of a control rod system at the upper portion thereof, ultimately enabling the simplification of a control rod driver 5 and the dropping of a control rod 4 by the dead load in case of a trouble.
