Abstract: This anchor support tool supports an anchor provided in a foundation, the anchor support tool comprising: a support plate having at least one support part for supporting an anchor; a spacer for positioning the support plate with respect to a form of the foundation in the height direction; and a fixing jig for fixing the support plate to the form. The fixing jig supports the support plate while the support plate is disposed above the form with the spacer therebetween.

Abstract: This foundation construction method for a building includes: a first step for creating a foundation base; a second step for installing reinforcement on the foundation base; a third step for installing a frame for creating a foundation to be provided to the foundation base; a fourth step for arranging a plurality of anchors so as to follow the inner periphery of the frame; and a fifth step for placing concrete inside the frame. In the fifth step, the concrete is leveled such that the upper surface of the concrete is the same height as the upper end surface of the frame.

Abstract: A marine vessel propulsion system includes multiple propulsion devices, multiple operation levers, and multiple lever position sensors arranged to detect the positions of the multiple operation levers, and a control unit. The control unit is programmed to control, based on detection results from the multiple lever position sensors, the shift states of the respective propulsion devices and to change the steering angle of at least one of the propulsion devices. The control unit may be arranged to change the steering angles of the propulsion devices to facilitate the behavior of the hull corresponding to the shift states of the respective propulsion devices.

Abstract: A marine vessel propulsion system includes first and second propulsion devices, a first operation lever arranged to be operated by a marine vessel maneuvering operator to control the first propulsion device, a second operation lever arranged to be operated by the marine vessel maneuvering operator to control the second propulsion device, a first lever position sensor arranged to detect a position of the first operation lever, a second lever position sensor arranged to detect a position of the second operation lever, and a control unit. The control unit is programmed to set a target pivoting speed according to the positions of the first and second operation levers relative to each other and set a target travel speed according to amounts of displacement of the first and second operation levers with respect to neutral positions.

Abstract: A steering apparatus for a propulsion device includes a swivel portion, a motor, a lock portion, and a lock release mechanism. The motor is arranged to generate a driving force to turn the propulsion device main body in right and left directions. The lock portion is provided in a transmission path of the driving force. The lock portion is arranged to transmit a force from an upstream side to a downstream side thereof and to be locked when a force is applied from the downstream side to thereby prevent a turning of the propulsion device main body in the right and left directions. The lock release mechanism is provided in the transmission path at the downstream side relative to the lock portion. The lock release mechanism is arranged to shut off or stop a transmission of force to the upstream side thereof to thereby prevent application of the force to the lock portion.

Abstract: The present invention relates to a microbiological process for the production of citric acid by assimilation of .alpha.-olefins, normal paraffins and their mixture. This process is carried out by culturing the microorganisms selected from the group of Candida tropicalis, Candida lipolytica, Candida intermedia and Canida brumptii and their mutants and their variants under higher concentration of dissolved oxygen than that in ordinary aeration in the culture medium. The concentration of dissolved oxygen in the culture medium is suitable in the range of from 5 to 40 ppm, preferably from 10 to 30 ppm on the weight basis of said culture medium in this invention.There is many means of which increase the dissolved oxygen in the culture medium.
