  • Patent number: 5912058
    Abstract: Sheets of laminated paper are stacked and made into air-tight flat bags with air inlets. After air is supplied into the bags, the air inlets are air-tightly closed to form shock absorbers 50 encapsulating the air. The laminated paper is made by stacking on a paper base a water-soluble polyvinyl alcoholic layer, having a saponification of 80 to 90 mol % and a degree of polymerization of 500 to 2500, to a total thickness of 90 .mu.m or less and a gas permeability of 800 thousand seconds per 100 ml or more. The air is introduced into flat bags 51 to 50 to 80% of maximum inflation to ensure their shock absorbing function. A package 100 is made by putting an appropriate number of discrete shock absorbers 50, or a continuous series of shock absorbers 50, in gaps between a casing 10 and the package content 70. The shock absorbers 50 need not be spread all over the entire surface of the package, so long as they are sufficient to provide the needed contact area to ensure a maximum static load of 0.07 kgf/cm.sup.

  • Patent number: 5755082
    Abstract: Equipment which automatically manufactures cushioning material by filling air inside polyvinyl alcohol laminated paper and sealing the filled material into individual bags. The manufacturing equipment 1 is provided with a material roll 20 on which a sheet material of polyvinyl alcohol laminated paper is wound. The sheet material 10 is rolled out by a feeding roller 40 from the material roll 20, and the sheet material 10 in a known length, adjusted by a length adjusting device 50 having a roller 42 which goes up and down, is supplied intermittently to a bag forming device 100 located downstream thereof. The bag forming device 100 is provided with a pipe member 105 and a sailor 110, which is a guide plate to reverse the sheet material 10 and form it into a tubular shape, and the sheet material 10 is fed along the pipe member 105 after being formed into a tubular shape. Feed rollers 130 and auxiliary belt 120 are arranged at the periphery of the pipe member 105.

  • Patent number: 5557736
    Abstract: In an electronic mail associated type computer system network equipped with a computer system for executing a job and a general-purpose electronic mail system, a user of an electronic mail can freely recognize a condition of an execution result of a job performed in the computer system and a job execution result. Also, these results are available from a desired output device for the user. When a mail processing unit employed in the computer system analyzes a mail statement about the job execution derived from the electronic mail system, and the job execution is completed, this mail processing unit sends to the electronic mail system, such a mail statement for the completion of the job execution containing information about fail/safe execution result. Upon receipt of this report, the user designates the output device into a response mail so as to output the job execution result from the designated output device.

  • Patent number: 5537543
    Abstract: In an arrangement of a mail terminal 1, an electronic mail system 2, a job control terminal 4, and a computer system 3, a user makes a proposal of a file operation via a mail by way of the mail terminal 1. The electronic mail system 2 stores therein the proposal mail, exchanges this proposal mail with the job control terminal 4, and furthermore distributes a file operation result to the respective mail terminals. The job control terminal 4 receives a mail from the electronic mail system 2, and interprets the proposal mail, thereby executing a conversion from a mail ID into a host ID, a judgement of an access authorization with respect to the designated file, and a production of an instruction to the computer process system 3. Furthermore, an execution host computer is selected by monitoring operation conditions of the host computers.

  • Patent number: 5408334
    Abstract: A job control terminal creates a unit configuration table indicating the configuration of units connected to each of a plurality of processors in a multi-processor system. The job control terminal also creates an operating state table indicating an operating state of each processor including a CPU using ratio, I/O using ratio, memory using ratio, response time, and so on. When the job control terminal receives electronic mail for requesting job execution from a user through an electronic mail terminal, the job control terminal selects a processor assigned to execute the requested job based on the unit configuration table and the operating state table. When it is determined from the states of the processors that the requested job cannot be executed, information indicating that the job is unacceptable is transmitted from the job control terminal to the electronic mail terminal.

  • Patent number: 5394550
    Abstract: In compiling a source program by a compiler and sequentially generating an intermediate code, the intermediate code is managed by referencing it to the corresponding statement of the source program. When an error is detected during the compiling operation, the operation is stopped. After the error is corrected, the compiling operation resumes. In this case, the compiling operation starts not from the start of the source program, but from the error detected location of the source program. Compiled intermediate codes are added to the previously compiled correct intermediate codes.

  • Patent number: 5237677
    Abstract: Fault monitoring/controlling apparatus and method for a data processing system comprises one or more computer systems, monitor and control apparatuses connected thereto for monitoring and controlling the associated computer systems and a single supervision/control system provided at a site remote from the computer systems. When abnormality taking place in the computer system is decided as a fault, report of the fault occurrence is automatically effectuated to the remotely located supervision/control system, which responds to the reception of the fault report and issues, if necessary, a command requesting additional supply of detailed fault information to the computer system suffering the fault. The additional fault information is comparatively collated with the fault information accumulated (precedents).
