Title: Production of combustible gas detecting element
Inventor: IGA ATSUSHI
IPC: G01N27/16
Filed: 1978-04-19
Abstract: PURPOSE: To let the contact combustion type combustible gas detecting element operate stably over a long period of time for combustible gases of a wide range of kinds including CH 4  by providing the specific oxidation catalyst on a Pt resistor.  
     CONSTITUTION: A Pt layer 3 is formed on an alumina substrate 2 by using Pt paste and Au electrodes 4 are formed at its both ends by using Au paste. After Au wires 5 are mounted to the electrodes 4 of this element, these are welded to a pair of stainless steel made pins 7 studded to a stem 6. Next, a carrier baked with γ-Al 2 O 3  is formed in the central portion of the element 1. An aqueous solution of precious metals such as Pt, Rh, etc. is impregnated in the carrier and is thermally decomposed in a H 2  containing atmosphere, whereby the carrier catalyst 8 is formed. This combustible gas detecting element is put on with a metal screen 9 made of stainless steel and constitutes a bridge together with the hermetically sealed similar compensating element, fixed resistance and variable resistance.

Title: Device for preventing roller streak of roller device for printer
Inventor: YANKO DESUPOOTO
IPC: B41F31/30
Filed: 1983-03-23
Abstract: In a rotary printing machine, an arrangement for mounting an applicator roller and a preceding roller in a fluid feed stream journals the applicator roller and the preceding roller to the printing machine frame with substantial bearing play, and spring loads the applicator roller against the bearing surface away from the plate cylinder. On passing through the cylinder gap the applicator rollers of inking, damping or varnishing units in sheet-fed offset presses are jolted both at the start and end of the gap. The resulting different flattening of the soft applicator rollers causes roller marks, which should be avoided. For this purpose the applicator roller and the preceding roller are braced against each other by springs, so that their bearing play is eliminated and the distance between shafts is constant. This condition is also maintained on passage through the gap. Conveyance of liquid between applicator rollers and the preceding rollers is thus constant.

Abstract: PROBLEM TO BE SOLVED: To accurately evaluate the degree of stabilization of the rust layer of a weather-resistant steel and to investigate the degree of rust stability of a constructed structure by performing the microscopic analysis of the section of the rust layer formed on the surface of the steel material. SOLUTION: The microscopic analysis of the section of a rust layer being caused on the surface of a weather-resistant steel material is made to evaluate the stability of the rust layer of the weather-resistant steel material. More specifically, a crack part existing in the rust layer is extracted by an optical microscope image, the crack density of the extracted crack part is determined, and the stability of the rust layer of the weather-resistant steel material is evaluated. For example, in the bright visual field optical microscopic photo of the sectional structure of stable rust being caused in the weather-resistant steel whose thickness has decreased, the rust layer and a crack are extracted. In this manner, the degree of the crack existing in rust being observed from the section of rust is evaluated.  Specifically, the length of the crack existing per the sectional area of rust adhering onto the steel material on a sectional microscopic photo that is picked up by cutting and polishing the steel material is measured.

Title: Fault processing system
Inventor: TAKEDA KATSUMI
IPC: G06F13/00
Filed: 1979-04-20
Abstract: PURPOSE: To prevent previously the propagation of the machine check and thus to increase the reliability, by informing the fault occurred to the main memory device and while the request from one unit of CPU is being processed not only to the CPU which transmitted the request but also to all CPUs sharing the main memory device.  
     CONSTITUTION: Both CPU0 and CPU1 are connected to main memory device MS to form the information processor. And when start signal EX is transmitted to device MS from CPU0, the fact that signal line 8 from FF7 of device MS is logic 1 is confirmed through AND gate 2. Then signal EX is transmitted to device MS. Receiving signal EX, device MS starts the processing, and then set FF7 in case the recovery unable fault is detected in the course of processing. And CPU0 detects the time-out check since no action end signal ADV is sent back. In such condition, AND gate 5 is not set up since the state of line 8 features logic 0 although CPU1 tries to transmit signal EX. Thus no signal EX can be transmitted, and as a result, the propagation of the machine check can be prevented previously.

Abstract: PROBLEM TO BE SOLVED: To automatically detect a change into a state of formed dislocations in a single crystal, thereby reduce a load on an operator and automate operations to remelt the single crystal at the time of the occurrence of the change into the state of the formed dislocations in the process of pulling up the single crystal by a Czochralski method (CZ method). SOLUTION: The shape of an outer peripheral surface of a single crystal B pulled up from a melt A or the shape of a fusion ring formed in the periphery of the interface between the melt A and the single crystal B is monitored with a camera 20. The disappearance of a seam part produced as the result of the crystal structure of the single crystal on the outer peripheral surface in the form of a vertical rib is detected by a change in the shape of the outer peripheral surface or the fusion ring. The occurrence of the change into the state of formed dislocations is detected by the disappearance of the seam and remelting operations of the single crystal are carried out on the basis of a prescribed program.  The contact and separation of the single crystal B from the melt are detected from a change in voltage applied across the melt A and the single crystal B according to the remelting program to intermittently lower the single crystal B.
