Title: Enriched zone of layer formed by vapor phase carburization and slow cooling of sintered carbide substrate and method for formation thereof
Inventor: SUTEIIBUN ERU BENETSUTO
IPC: C04B35/64
Filed: 1994-05-19
Abstract: PURPOSE: To provide a method for carburizing sintered carbide substrates having a wide range of thicknesses and a wide range of initial carbon levels.  
     CONSTITUTION: An untreated sintered carbide substrate is deyaxed in a vacuum furnace. The temp. of the furnace is slowly elevated to the sintering temp. of the sintered carbide substrate at about 5-10°C/min rate. Gaseous methane or a gaseous methane-hydrogen-mixture is introduced at the sintering temp. under reduced pressure for a time sufficient to saturate the binder of a large- sized member having a deficient initial carbon content from the substrate with carbon. The gaseous methane or the gaseous methane-hydrogen mixture is discharged and an inert gas from the group VIII of the(periodic table is introduced. The furnace is then slowly cooled to a temp. below the solid phase temp. of the substrate at a prescribed rate. The objective stratified enriched zone is formed on the surface of the substrate.

Title: Switch mechanism for circuit breaker
Inventor: ASAHI NOBUO
IPC: H01H73/02
Filed: 1992-04-21
Abstract: PURPOSE:To eliminate assembling impossibility if a torsion error is generated between hook portions at both ends of a switch spring. CONSTITUTION:A sufficient clearance is formed between a spring hook piece 1a of an operating lever 1 and a hook portion 2a of a switch spring 2 to be hooked on the spring hook piece 1a. A projection 5 for preventing the hook portion 2a from being drawn out is formed on the spring hook piece 1a. Accordingly, because the hook portion 2a becomes free from the spring hook piece 1a to some extent, a toggle pin 3 can be kept to be directed in the predetermined direction even if a torsion error is generated between a hook portion 2b to be hooked onto the toggle pin 3 for connecting an upper link of a toggle link to a lower link thereof, and the hook portion 2a. Consequently, the toggle link can be assembled without any difficulty.

Abstract: A heat exchanger in which a plurality of tubes are supported by tube sheets within a shell having inlet and outlet heads connected to its ends. One of the heads and tube sheets are secured directly to one end of the shell while the other tube sheet and head form a floating head assembly which is connected to the other end of the shell by an expansion joint to permit relative movement between the head assembly and the shell. A first heat exchange fluid is passed into the inlet head and through the tubes before discharging from the outlet head, and a second heat exchange fluid is passed through the shell in a heat exchange relation to the first heat exchange fluid. A load is applied to the head assembly in the direction of the shell to preload the tubes in compression, and movements of the head assembly relative to the shell in excess of a predetermined amount are prevented.

Filed: 1991-05-31
Abstract: PURPOSE:To obtain the apparatus capable of being driven by low voltage by providing a piezoelectric transducer, a plate and a communication part and applying a predetermined electric field to the piezoelectric transducer and deforming ink passages to inject ink. CONSTITUTION:For example, when a jet device 31b is selected according to predetermined printing data, a driving electric field is applied across metal electrodes 11e, 11e and 11e, 11f and, since the driving electric field direction crosses a polarizing direction at a right angle, side walls 2b, 2c are deformed in the internal direction of the ink passage 31b by piezoelectric thickness slide effect and the volume in the ink passage 31b is reduced to increase the pressure of ink to inject an ink droplet from an orifice. Since a gaps 6 are narrow, the amount of the ink moving through the gaps 6 is slight and almost no effect is exerted on the injection of the ink. By providing the gaps 6 over the total length of the ink passage 31b, the quantity of deformation of the side walls 2b, 2c sufficient to inject the ink droplet can be obtained even by low driving voltage.
