Abstract: An outer circumferential surface of a trunnion shaft includes a sliding contact region that has a circular arc shape as viewed along a slanting axis line and is substantially brought into contact with an inner circumferential surface of the bearing portion in a rotatably sliding manner, and at least one suction groove that forms a pocket portion between the suction groove and the inner surface of the bearing portion. The pocket portion is opened to an inner space of housing on at least one side in an axis line direction of the trunnion shaft.

Abstract: An axle case, housing therein axles and a transmission for driving the axle, provided with a mount boss for being mounted to case mounting portions provided on a body frame of a vehicle and having insertion bores for mounting bolts, and including vibration isolating members which are each fixedly positioned on each mount boss and are provided with a portion positioned thereon and a portion extending into the insertion bore, so that, when the mount boss is coupled with the case mounting portion, the portion of the vibration isolating member positioned on the mount boss contacts with the case mounting portion. Thus, the axle case and body frame can be simply coupled with each other by using the vibration isolating members. The axle case is preferably divided vertically into an upper and a lower portion through a horizontal joint surface.

Abstract: An axle driving apparatus has in a housing a hydrostatic transmission with a variable displacement type hydraulic system having a slantingly movable swash plate. In one embodiment, the movable swash plate is manually slantingly operable. A leg member integrally extends from an inner wall of the housing, a lid for closing an opening of the housing, or a center section. The leg member has a support portion for supporting a shaft provided on an axis of rotation of the movable swash plate. Accordingly, the movable swash plate is suspended in the housing for slanting or pivoting movement.

Abstract: 12.alpha.-Substituted pregna-1,4-diene-3,20-diones, which are novel compounds, are provided. These compounds are useful as intermediates for the synthesis of antiinflammatory corticoids represented by prednisone, prednisolone, etc.

Abstract: There are provided 12-hydroxy-.DELTA..sup.4 or .DELTA..sup.1,4 -pregnan-3-one-20-carbaldehyde and microbial method of producing the same. The compounds are novel and useful as starting materials for the synthesis of corticoids, typically prednisone, prednisolone and hydrocortisone, which have antiinflammatory activity.

Abstract: A switchboard control system in which a plurality of switchboards are connected to a time division exchange and controlled by the time division exchange. A speech signal and a control signal (a signal for key information, display information, subscriber number information and other information necessary for the exchange operation by a switchboard operator), which are delivered and received by each switchboard and the time division exchange, are transmitted together by a common transmission line on a time-division-multiplexed basis. On the side of the system toward the switchboards are disposed a position controller, by which the signals are multiplexed and separated and the common transmission line and the switchboards are interconnected. For delivering and receiving the signals, common channel signalling equipment is connected to the time division exchange and remote channel signalling equipment is provided in the position controller.

Abstract: A centralized supervisory system in an automatic switching system including at least one remote office with a first time-division switching system and a first supervisory unit, and a central office with a second time-division switching system and a second supervisory unit. The first time-division switching system and the second time-division switching system being connected by a time-division multichannel line. Supervisory data output from the first supervisory unit are allocated to one or more predetermined channels on the time-division multichannel line, so that the supervisory data output from the first supervisory unit are transferred through the time-division multichannel line to the second supervisory unit and are centrally supervised therein.

Abstract: A microbial process for producing 12.alpha.-hydroxypregna-1,4-dien-3-one-20.alpha.-carboxylic acid or a salt thereof which comprises cultivating a microbe of the species Pseudomonas arvilla or the genus Alcaligenes, e.g. Alcaligenes faecalis, which is capable of producing 12.alpha.-hydroxypregna-1,4-dien-3-one-20.alpha.-carboxylic acid or a salt thereof by utilizing deoxycholic acid or a salt thereof as a substrate, in a culture medium containing the substrate and collecting the resulting compound.
