摘要:
In conventional radio controlled models, a receive frequency is changed with a changeover switch mounted in a receiver body. In the present invention, a frequency switching scheme, employing a radio system in which a transmitter switches the receive frequency, is provided. Using weak radio waves usable without authorization, the transmitter transmits frequency data set therein as a frequency switching signal to a receiver. In the receiver, the receive frequency is set to a predetermined weak radio wave frequency when the power source is turned on. Upon receiving the weak radio waves, the receiver reads the frequency data out of the set signal and stores it into the memory means. Thus, the frequency setting has been completed. When the receiver does not receive the frequency switching signal for a fixed period of time, it reads out the frequency data used previously from the data memory to start the receiving operation.

An access performance adjusting method is adapted to a storage apparatus having a storage to prestore a skew quantity that is used to shift a data write starting position of each track of a recording medium depending on a head moving time required to move a head from one track to another track during a sequential access in which a plurality of tracks of the recording medium are accessed sequentially. The method includes measuring an apparatus performance with respect to a combination of the head and the recording medium, calculating a skew adjusting quantity with respect to the combination based on a reference apparatus performance and the measured apparatus performance, and adjusting the skew quantity read from the storage by the skew adjusting quantity and storing the adjusted skew quantity in the storage as an updated value of the skew quantity.

An engine for radio controlled models includes an internal combustion engine and a radio control receiver having a control unit for generating a fuel injection signal to control the supply of fuel to the internal combustion engine and a throttle adjusting signal to control an opening of a throttle value. The control unit provides a fuel injection signal based on fuel injection timing which is derived from a stroke signal and control unit provides a fuel injection timing signal to cause the fuel injector of the internal combustion engine to inject fuel into the combustion chamber of the engine.

A sheet storing/feeding device includes a receptacle for holding standing sheets, a stacking and feeding mechanism to successively carry the sheets into the receptacle and to feed a forefront sheet out of the receptacle. A pushing member configured to be optionally advanced and retracted is provided on the side of the forefront sheet in the receptacle, and a holding member is provided to be in contact with a backmost sheet in the receptacle. A retaining member is provided to be optionally advanced and retracted relative to a storage space defined between the stacking and feeding mechanism and the holding member. The retaining member, when advanced, can hold the sheets in the receptacle between the retaining member and the holding member so as to bring them into a temporary holding state, while, when retracted, can release the paper-sheets in the temporary holding state.
摘要:
A magnetic disk device regularly monitors an abnormality in heads and, when detecting an abnormality in any head, transfers data in each cell corresponding to the head where the abnormality is detected to a replacement cell corresponding to another head. Then, in a management table, the magnetic disk device updates the logical address of the transfer-destination cell to the logical address of the transfer-source cell. Thereafter, the magnetic disk device deletes the data in the transfer-destination cell from the management table.

There is disclosed a process for producing an olefin oxide characterized by contacting an olefin and oxygen, in the presence of water and a halogen compound, with a silver catalyst, wherein the silver catalyst is a silver catalyst that is obtainable by contacting metal silver, a silver compound or a mixture of both with an alkaline earth metal carbonate and that has an alkali metal content of 1,500 ppm or less based on the total weight of the silver catalyst
摘要:
In a maintenance/recovery device for a liquid discharging device, a cap member covers a surface of a nozzle of a liquid discharging head, the liquid discharging head discharging a droplet of a recording liquid from the nozzle. A resilient contact member is provided in the cap member to come in contact with the surface of the nozzle. A recess-forming member is providing in the cap member to form a recess for receiving the recording liquid attracted from the nozzle. The contact member and the recess-forming member are integrally formed by molding, the recess-forming member is made of a resin material containing a water repellent agent, and the recess-forming member is provided to have at least two slopes being inclined toward an outlet at a bottom of the recess.
