Title: Compressor
Inventor: FUJII MITSURU
IPC: C22C37/00
Filed: 1983-12-29
Abstract: PURPOSE:To reduce the thermal expansion coefficient of screw rotors and the gap therebetween and as well to aim at greatly enhancing the efficiency of compression, by forming the screw rotors from alloy in a specific composition consisting of 32-42wt% Ni as a main component and the remainder of Fe together with unavoidable impurities. CONSTITUTION:Each screw rotor is formed of Fe-Ni group alloy consisting of 32-42wt% as a main component and the remainder of Fe together with unavoidable impurities, Fe-Ni-Co group alloy consisting of 32-46wt% Ni+Co as a main component and the remainder of Fe together with unavoidable impurities or Fe-Ni group cast iron consisting of less than 2.4wt% C, less than 2wt% Si, less than 1wt% Mn, 35-42wt% Ni and the remainder of Fe together with unavoidable impurities. With this arrangement, the thermal expansion coefficient of the rotor becomes about 6X10<-6> less than one-half of that of conventional rotors and therefore, the gap between the rotors upon assembly at a room temperature may be reduced to about one-half of conventional rotors, and therefore, the efficiency of compression may be greatly improved.

Title: Switching amplifier
Inventor: FUJISAWA MASANORI
IPC: H03F3/217
Filed: 1986-10-17
Abstract: PURPOSE:To attain a power amplifier to an analog and a digital input signal with high efficiency by providing a means switching selectively an analog or digital input signal selectively so as to amplify the analog or digital signal switchingly. CONSTITUTION:When the input signal fed to an analog input terminal 11 is an analog signal such as an audio signal, a changeover switch (SW) 24 is switched to the position of the analog input mode to turn on SWs 22, 23 and the switching amplifier circuit 13 is selected. Thus, the signal is subjected to a pulse width modulation by a modulator 15 and amplified with high efficiency by using the circuit 13. When the input signal fed to a digital input terminal 21 is a digital signal, the SW 24 is switched into the digital mode to turn off the SWs 22, 23 to disconnect the modulator 15 and the negative feedback circuit 19. Then the signal is sent to the circuit 13 directly or via the digital converter 26. Thus, the analog and digital input is subjected to the power amplification with high efficiency.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To efficiently dissipate heat released from a semiconductor device, so as to prevent an element from deteriorating in strength and difficulties from occurring in a manufacturing process by a method, wherein heat dissipating fins are provided to the surface of an electrode or a wiring. SOLUTION: Wing-shaped heat dissipating fins 5, formed of a metal film provided through a sputtering method, is formed on the upsides of a drain electrode 3 and a source electrode 2. Normally most of the heat released from a FET is emitted from arm active layer, so that the heat released from the FET is conducted to electrodes 2, 3, and 4 formed of metal high in thermal conductivity and partially dissipated into the air. The heat-dissipating properties of the electrodes 2, 3, and 4 are dependent on their surface area, and the source electrode 2 and the drain electrode 3 are enhanced in area by heat dissipating metal fins 5, so that heat released from the FET is effectively discharged outside from it. By this setup, an FET is restrained from rising in temperature and reduced in thermal resistance.
