摘要:
There is provided a system control method which reduces maximum energy consumption in a tracking-type photovoltaic power generation system having a plurality of tracking-type photovoltaic power generation devices and reduces energy supply capacity. An integrated control part drives driving parts in each of tracking-type photovoltaic power generation devices at predetermined time intervals and drives the driving parts at different times, which can disperse temporally the large energy consumed at the time of activation of the driving parts in the tracking-type photovoltaic power generation devices, thereby reducing the energy supply capacity.

A data transfer apparatus referred to as a primary-recording-medium apparatus implements proper system operations by acquisition of information on a secondary recording medium mounted on a secondary-recording-medium apparatus to serve as a destination of a transfer (or a check-out) of a content. If a medium adopting its own unique management technique as is the case with a mini disc is used as the secondary recording medium serving as a destination of a check-out, the primary-recording-medium apparatus acquires information on the secondary recording medium from the secondary-recording-medium apparatus, which is typically a data-recording apparatus. The information includes an indicator as to whether or not the secondary recording medium has been mounted on the data-recording apparatus, the name of the secondary recording medium, the name of each content stored in the secondary recording medium, the number of contents stored in the secondary recording medium and attributes of each content stored in the secondary recording medium.

The present invention provides a process for efficiently producing sporangia of Bacillus popilliae containing spores and parasporal bodies having controlling effects on Scarabaeidae insects, and a control agent and controlling method for Scarabaeidae insects obtained by said production process. In a process for producing sporangia of Bacillus popilliae containing spores and parasporal bodies by culturing Bacillus popilliae in a medium containing an adsorbent, the medium contains 0.2-4.0% by weight of glutamic acid.

The present invention is to produce an aluminum nitride powder which is turned into a sintered body at a temperature of not more than 1600° C., thereby obtaining a sintered aluminum nitride in which the density and thermal conductivity are high and which can be properly used as a substrate material. Using a vapor phase reaction apparatus shown in FIG. 1, ammonia gas was fed from a reactor 2 heated at from 300 to 500° C. and maintained at that temperature by a heating section 1 via a feeding tube 4 while being regulated by a flow regulator 3. At the same time, while being regulated by the flow regulator 5, nitrogen gas containing an organic aluminum compound is fed via a feeding tube 6 to obtain an aluminum nitride powder. The aluminum nitride powder is subjected to a heat treatment at from 1100 to 1500° C. in a reducing gas atmosphere and/or an inert gas atmosphere to obtain an aggregate aluminum nitride powder. The aggregate aluminum nitride powder is subjected to a mechanical treatment to obtain an aluminum nitride powder in which the specific surface area value is not less than 30 m2/g and a ratio of an average particle diameter to a particle diameter in terms of the specific surface area is not more than 10.

The present invention provides a process for producing sporangia of Bacillus popilliae containing spores and parasporal bodies in large numbers per unit volume of medium. In a process for producing sporangia of Bacillus popilliae containing spores and parasporal bodies by culturing Bacillus popilliae in a liquid medium containing an adsorbent, the liquid medium contains 0.1-0.7% by weight of proline.

A terminal connection device changes and connects a plurality of terminals to one telephone line according to kinds of ringing signal sequences sent through the telephone line. The terminal connection device comprises switches connecting between the telephone line and the terminals, a control circuit commanding ON/OFF operation of the switches, and a photo coupler converting the ringing signal obtained through the telephone line into light signal and inputting the light signal to the control circuit. The control circuit includes a device for judging as to whether a ringing signal sequence sent through the telephone line is the same as the sequence data or not.

A self-canceller for a turn signal indicator comprises the following features: (a) its body has a retaining element with three recesses formed therein; (b) the body is provided with a movable bracket capable of rotating; (c) a control lever is fastened to the movable bracket; (d) two side stoppers, a center stopper, and a spring housing are fastened to the movable bracket; (e) an engaging ball and a compression spring are contained in the spring housing; (f) a ratchet mount is provided between the center stopper and the compression spring; (g) the compression spring is supported by the engaging ball at one end and by the ratchet mount at the other end; (h) the engaging ball can be engaged with any of the three recesses of the body according to the rotary movement of the movable bracket; (i) two cancel ratchets are formed on the ratchet mount; and (j) when the cancel cam moving in the rotating direction of the control lever makes contact with either of the cancel ratchets, the ratchet mount can rotate about a point on the center stopper as a pivot against the compressing spring. When one of the cancel ratchets of the ratchet mount contacts and interferes with the cancel cam during the movement of the ratchet mount by the operation of the control lever, depending on the rotating position of the steering wheel, it is necessary to add only a very small force for compressing the compression spring, as opposed to the otherwise ordinary control force previously necessary, to operate the control lever against such interference.
摘要:
A time difference switch turns on and off two electric circuits, under the operation of a common operating member, with an adequate time difference. The section of the switch that defines a step dimension that facilitates the time difference is relatively short, and for this reason, the likelihood of a change in the predetermined step dimension, i.e., in the time difference, is lessened. Thus, a time difference switch providing a predetermined accurate time difference is provided.
