Title: Multi-processor system
Inventor: ISHIHARA MASAKAZU
IPC: G06F15/177
Filed: 1988-06-13
Abstract: PURPOSE:To improve the communicating capacity of a system by making a transmitting side processor identify the crowding state of the receiving transaction of a receiving side processor according to the means of a shared memory to indicate the crowding state, and making it transmit communication when it is not in the crowded state in the case of the communication among plural processors. CONSTITUTION:When a communicating request is generated in a central processing unit 1a to be the transmitting side, it reads the state of the receiving transaction of the central processing unit 1b to be the receiving side from the shared memory 3, and in the case of a not crowded state, it transmits the communication through a communication bus 2, and the communication processing of the transmitting side central processing unit 1a is terminated. Subsequently, after the receiving transaction is released in order to restart the communication from other central processing unit, the number of pcs. of remaining idle receiving transaction is checked again, and in the case that is increased more than a standard value, the crowing indication of the shared memory 3 is released. Thus, the communicating capacity of the system can be improved.

Title: Aluminum alloy composite material for heat exchanger
Inventor: FUJITA KOICHI
IPC: C22C21/00
Filed: 1992-05-13
Abstract: PURPOSE:To reduce the thickness and weight of the material and to improve the strength thereof by cladding an Al-Si brazing filler metal on one surface of an Al-Cu-Zn core material having a specific compsn. and cladding an Al alloy sheath material to be a sacrificial layer on the opposite surface. CONSTITUTION:The core material is composed, by weight %, of 0.1 to 1.5% Zn, 0.2 to 1.0% Cu, 0.2 to 2.0% Mn and the balance Al and unavoidable impurities. The Al-Si brazing filler metal is clad on one surface of this Al alloy core material and the Al alloy sheath material to be the sacrificial layer is clad on the opposite surface. This sheath material is preferably an alloy having the compsn. consisting of 0.3 to 2.0% Zn and the balance Al and unavoidable impurities. The strength of this Al alloy composite material is improved by adding the Cu to the core material. The decrease in the potential difference from the sheath material arising therefrom is prevented by adding a proper ratio of the Zn to the core material. The effect as the sacrificial anode layer of the sheath material is thus maintained.

IPC: G06F3/02
Filed: 1991-06-19
Abstract: PURPOSE:To prevent malfunction owing to the drop of dust and that at the time of unprepared touch. CONSTITUTION:When an upper cover 6 is depressed by a finger, the light of a light-emitting element 11 is blocked by the upper cover 6 by depressing it by the finger, and a light-receiving element 21 becomes an off-state. When the finger is released, the light of the light-emitting element 11 reaches the light-receiving element 21, and the light-receiving element 21 becomes an on- state. The position of a depressed Y-axis can be detected by recognizing the light-receiving element in the off-state by the light-emitting element. The operation is the same as in an X-axis and the position of the X-axis can be detected. The depressed position can be detected by a crossing position on the X and Y-axes.

Title: Aluminum alloy laminated heat exchanger with excellent corrosion resistance
Inventor: TAKENO SHINJI
IPC: B23K101/14
Filed: 1992-05-14
Abstract: PURPOSE:To improve corrosion resistance by bringing a brazing material of an inner skin material into contact with that of a multi-skin material through a polygonal hole or slit at the time of brazing, and using as a fin material aluminum or its alloy having a baser potential than that of a core material of a core plate. CONSTITUTION:Of brazing material joints of two types of a brazing material joint 15 connected with an inner skin material 12 and a brazing material joint 14 connected with an outer skin material 11, the former is formed by integrating a nobler brazing material of an inner surface. Accordingly, since its potential is nobler than that of a core material 10, the material 12 of the joint 15 is protected in a sacrificially corrosive manner for the material 10 and no corrosion to penetration occurs. A potential of a brazing material 24 is affected by influences of both the materials 11, 12 at the other joint 14 to becomes substantially the same level as the potential of the material 10. That is, the joint 14 is formed mostly by integrating the material 11 of the baser outer surface, and hence the material 24 is affected by influence of the material 11. Thus, the joint 14 is not penetrated by corrosion.

IPC: H01L23/31
Filed: 1988-06-16
Abstract: PURPOSE: To reduce the unnecessary force applied to a circuit element in a circuit package with a chimney-like section by constituting the chimney-like section so that the section can form a thermal expansion relieving path when a soft silicon coating material expands due to the heat from the circuit element so that a ceramic substrate can be prevented from being pushed to the outside of an enclosure due to the thermal expansion of the soft silicon coating material. CONSTITUTION: A chimney-like section 20 is formed downward through an enclosure 10 so that the section 20 can reach a soft silicon coating material 14. The section 20 has a lower opening 22 above a ceramic substrate 4 and below the boundary portion 24 between an epoxy resin 16 and the silicon material 14. The section 20 prevents the substrate 4 from being pushed to the outside of the enclosure 10 due to the thermal expansion of the silicon material 14 by forming a thermal expansion relieving path when the silicon material 14 is heated. Therefore, the unnecessary force applied to a circuit element is reduced.

Abstract: PURPOSE:To exactly measure the concns. of low-concn. ClO2 and Cl2 by obtaining the concn. of the ClO2 in the air after the ClO2 is thermally cracked by heating air contg. the ClO2 of a known concn. to a specific temp. and determining the correlation equation existing between the two concns. CONSTITUTION:The measurement of the concn. of the gas in the space 21 to be measured is executed by a gas detecting tube and the average value at the four points of sampling holes S-1 to S-4 is obtd. First, Cy+Cx/0.6=Cm1 (0.6 is the coefft. by the detecting tube) is obtd. when the concns. (ppm) of the ClO2 and Cl2 in the space 21 before the heating are designated respectively as Cx and Cy and the reading of the detecting tube (concn. of the gaseous mixture) is designated as Cm1. Then, Cz=Cx/2, hence Cy+Cx/2=Cm2 are obtd. when the concn. of the Cl2 generated by the thermal cracking after the gas in the space 21 is sampled into a heating tube 23 and is heated to 100 to 150 deg.C by a mantle heater 24 is designated as Cz and the reading of the detecting tube as Cm2. From two equation, Cx=(Cm1-Cm2)/1.16 is obtd. The concn. Cx of the ClO2 before the heating is calculated by these equations without separating the ClO2 from the Cl2. The concn. Cy of the Cl2 before the heating is calculated by substituting this value into the first equation.
