Laser beam is irradiated on the surface of the work piece 1 and the coat 2 is removed in the shape of a predetermined pattern so as to form patterned parts 1a. The work piece 1 is dipped in etching liquid for a fixed time and only exposed metal bases of the patterned parts 1a are dissolved and corroded so as to form grooves 13. Then, the work piece is dipped in solvent so as to dissolve and remove the coat 2 of the masking being remained on the surface. Accordingly, the surface of the work piece 1 will be constituted of surfaces 1b of the metal basis and the patterned parts 1a formed by the grooves 13.

Filed: 1992-03-30
Abstract: PURPOSE:To improve absorption efficiency and absorption capability by a method wherein a fan is installed within an absorbing space and then absorption liquid and refrigerant gas within the absorption space are agitated by the fan. CONSTITUTION:A turbine pump 10 is rotated in response to a pressure difference (a fluid pressure) of working liquid at a generator 1 (a high pressure side) and an absorber 4 (a low pressure side) so as to rotate an output shaft 11. In turn, an extremity end of the output shaft 1 is inserted into an outer case of the absorber 4 and a fan 12 is fixed.

Filed: 1983-04-28
Abstract: PURPOSE:To reinforce an opening edge part so as to improve its quality against a thermal crack, by compounding an inorganic fiber aggregate with the opening edge part of a combustion chamber comprising a cavity part on the top face of a piston. CONSTITUTION:In the case of a piston 11 cast from the metal such as an aluminum alloy and provided with a cavity part forming a combustion chamber 12 on the top face, an inorganic fiber aggregate 10 of ring shape is compounded in an opening edge part of the combustion chamber 12.

Abstract: PURPOSE:To simplify the control of each supergroup level by time-sharingly controlling the gain of a modulator by each pilot current from the output point of a frequency division multi-carrier transmitting device having pilot current in every occupied band. CONSTITUTION:A frequency division multiplex signal with pilot current inputted from a terminal 11 is frequency-converted into standard supergroup signals by a supergroup receiver 12 and sent to a supergroup transmitter 14 through filters 131-134. Each standard supergroup signal is frequency-converted into the original line frequency band by a modulator and sent out from an output terminal 19. An transmitting output from the output terminal is inputted to a terminal 16 of a control device 15 and pilot current is extracted from the input signal. The extracted current is converted into DC voltage, which is inputted to the gain control terminal of each supergroup modulator through a terminal 17. An address corresponding to each pilot current is outputted from a terminal 18 to select a gain control terminal connecting to each modulator time-sharingly. Thus, the level of each supergroup can be automatically controlled by simple configuration.
