Abstract: PURPOSE:To eliminate the dimensional limit of fine pattern by a method wherein a side part only of a patterned layer to be reformed is reformed using a residual mask layer on the patterned layer as a selective reforming mask to leave the reformed side part. CONSTITUTION:A polycrystalline silicon layer 30 to be reformed and a silicon nitride layer as a selective side reforming mask layer 40 are formed on a primer layer 10 for patterning the layer 30 to be reformed taking specified shape corresponding to the flat patterning to form a side part 35 externally exposed. The side part 35 only of exposed layer 30 to be reformed is exposed to thermooxidizing atmosphere to be selectively oxidized using the residual silicon nitride layer 40 as a mask to form a silicon oxide part in fine width W (reformed part)50. Then, the residual silicon layer 40 and the layer 30 not oxidized are removed by etching process furthermore a protective mask layer 22 is removed using the residual reformed part 50 as a mask to form a fine structure composed of the fine part of reformed part 50 or silicon nitride layer 22 below the former part 50.

IPC: F01C21/04
Filed: 1985-07-18
Abstract: PURPOSE:To ensure excellent lubricating properties, by a method wherein, during colddown, the oil pressure of an eccentric shaft is decreased by a hydraulic regulating valve, and a warming-up time is shortened through decrease of an amount of oil for cooling, meanwhile, during high rotation running during colddown, an oil pressure is increased through closing of a relief passage. CONSTITUTION:Oil is fed with a pressure to an oil passage 13 in an eccentric rod 6 supporting a rotor, and is further fed to a main bearing part supporting the eccentric shaft 6. In which case, a temperature-sensitive type hydraulic regulating valve 17 is mounted in an oil passage 13 at the one end of the eccentric shaft 6. The hydraulic regulating value increases the energizing force of a spring 17b with the increase in an oil temperature, and an oil pressure in the oil passage 13 is increased through increase of the opening actuating pressure of a valve body 17a. A valve member 19, opened and closed depending upon the number of revolutions of the eccentric shaft 6, is located in a relief passage 18 opened and closed by the hydraulic regulating valve 17, and outward movement of a valve body 19a to the outside by means of an centrifugal force produced occasioned by an increase in rotation of the eccentric shaft 6 results in closing of a valve seat 19c.

Title: Transmitter for data communication
Inventor: INOUE KOICHI
IPC: H04B7/26
Filed: 1989-06-20
Abstract: PURPOSE:To prevent transmission started up when no memory card is inserted by identifying the extracting state of the memory card to a connector with a continuous transmission prevention circuit, and stopping the operation of the circuit when the card is being extracted. CONSTITUTION:When a transmission start-up switch 6 is operated at the time of inputting data to a state input part 1, the continuous transmission prevention circuit 9 reads in the signal state of a memory card connection signal line 10, and the extraction state of the memory card 8 to the connector 4 is identified. When no memory card 8 is inserted to the connector 4, since the memory card connection signal line 10 is not connected to the ground and no connection signal (ground) is transmitted to the continuous transmission prevention circuit 9, it is judged that no memory card 8 is inserted to the connector 4, then, the operation is stopped. Therefore, no transmission instruction of the data to a transmission circuit 2 is issued. Thereby, the transmission circuit 2 sends no data inputted to the state input part 1 from an antenna 3 to a space even when the transmission start-up switch 6 is operated.
