摘要:
An electronic apparatus is provided with a main battery, semiconductor memories having a chip select input (active low), a backup battery, a pull-up resistor, a control unit for selecting one of the semiconductor memories, and a selection control line connected between the control unit and the chip select input. The selection control line is connected to the backup battery through the pull-up resistor. A switch for closing or opening the selection control line is connected between the selection control unit and the junction point of the control line and the pull-up resistor. A switch control unit is provided which controls the switch to open the control line when the semiconductor memory is powered by the backup battery. In another electronic apparatus having a detection circuit for detecting the voltage of the backup battery, the switch is closed only when the voltage is to be monitored.

A method of producing a stretched film comprising melt-coextruding a thermoplastic resin A and a thermoplastic resin B to produce a composite film 1 having both-end films 2 of the thermoplastic resin B arranged in parallel at both end portions of the main film 1a of the thermoplastic resin A in the direction of width thereof, stretching the composite film, and cutting and removing both end portions of the stretched film in the direction of width, wherein a film stretch stress value of the both-end films 2 is larger than a film stretch stress value of the main film 1a at the same stretching ratio. This minimizes an increase in the thickness at both end portions of the film in stretching the film and decreases the widths by which both end portions of the expensive resin film are to be cut and removed for producing a film.

In a maintenance management system and a method of providing engineering support, maintenance information concerning generating plants owned by a user is provided to a maker, and the maker analyzes such items of information, and manages the information in a structure maintenance management system. The user accesses the maintenance management system through the Internet, extracts information to be obtained from databases, and implements maintenance activities or drafts a plan. Engineers of the maker register maintenance information through an intranet, and provide engineering support for the maintenance activities promoted by the user.

The present invention provides a roller mill control method capable of automatically controlling a roller mill which is comparatively difficult to operate for operation in an optimum operating condition, and a roller mill controller for carrying out the roller mill control method. The roller mill controller stores beforehand a roller mill characteristic model representing the relation between changes in the values of the operating condition variables detected by a detecting unit (2) and operating parameters, restrictions on the values of the operating condition variables and the operating parameters, an index of performance for evaluating the values of the operating condition variables and the operating parameters. A Simplex algorithm calculation system (5) included in an optimizing control arithmetic unit (3) calculates changes in the operating parameters by a Simplex algorithm by using the roller mill characteristic model, the restrictions and the index of performance to select the values of the operating condition variables detected by the detecting unit (2) so that the index of performance is optimized under conditions meeting the restrictions, and then, a main control unit (4) controls the roller mill on the basis of new operating parameters.

A hydraulic apparatus such as a bleeder screw comprises an inner end, an outer end, and a main body extending between the inner end and the outer end. The main body includes a first section having a threaded outer peripheral surface a second section disposed between the first section and the inner end. The second section has a smaller diameter than the threaded outer peripheral surface of the first section, and an axial length of the threaded outer peripheral surface is less than an axial length of the second section. An internal fluid passage opens through an outer peripheral surface of the second section at a location between the inner end and the threaded outer peripheral surface, and the internal fluid passage opens through the main body at a location between the threaded outer peripheral surface and the outer end. Another hydraulic apparatus comprises a first fluid reservoir having a first reservoir chamber and a first reservoir outlet; a second reservoir having a second reservoir chamber and a second reservoir outlet; and a common fluid passage in fluid communication with the first reservoir outlet and the second reservoir outlet to flow fluid from both the first reservoir chamber and the second reservoir chamber to the atmosphere.

摘要:
A seal structure for a vehicle, which includes a door member and a seal member attached thereto. The seal member includes a horizontally extending upper seal lip which comes into elastic contact with a peripheral part of an opening provided on a vehicle body, and a vertically extending side seal lip which comes into elastic contact with another peripheral part of the opening. The upper seal lip and side seal lip are connected to each other by die forming, thus forming a connected portion thereof. The upper seal lip and side seal lip have, on a side of the connected portion to be proximate to the vehicle body when the door member is closed, a seal sheet member covering the connected portion.
