Title: Resistance welding method of aluminum alloy
Inventor: IWASA TAKASHI
IPC: B23K11/11
Filed: 1993-12-27
Abstract: PURPOSE:To efficiently weld aluminum alloys by utilizing a thermit reaction and eutectic reaction at the time of resistance welding. CONSTITUTION:This method comprises welding the aluminum alloys while interposing a powder mixture composed of magnesium powder and a metal oxide between the parts to be joined of these alloys an rapidly increasing the temp. of a molten part by the thermit reaction.

Title: Data communication equipment
Inventor: SAKAKIBARA TSUTOMU
IPC: H04M1/00
Filed: 1991-12-10
Abstract: PURPOSE:To allow the data communication equipment to quickly reply urgent data by devising the communication equipment to communicate with one equipment and to allow the other communication equipment to keep in standby based on the judgement of the degree of urgency of a content of a communication message when an interrupt call comes. CONSTITUTION:Upon the receipt of a notice from a terminal equipment 3, a monitor center equipment 1 uses an MPU 10 to identify a call signal detected by an NCU 14 through an I/O 14, sends a connection command to the NCU 14 and receives data via a MODEM 12. Upon the receipt of an interrupt call from a terminal equipment 4 during the reception of data, the equipment 1 makes judgement as to which of data from the terminal equipment 3 connected at present or from the terminal equipment 4 has a higher degree of urgency. When the data from the terminal equipment 3 have a lower degree of urgency, the MPU 10 gives a hooking command to a network control circuit 14 through the I/O 15 to select the telephone line thereby receiving the data from the terminal equipment 4. When the data from the terminal equipment 3 have a higher degree of urgency, the reception so far is continued. Since the terminal equipment is switched only when the data from the terminal equipment 3 have a lower degree of urgency and the data from the terminal equipment 4 are connected instead, the communication equipment copes with the urgency quickly.

Title: Pseudo lock detection circuit
Inventor: IWASAKI JUN
IPC: H04L27/227
Filed: 1991-12-13
Abstract: PURPOSE:To detect a pseudo lock state such as a locked PLL of a demodulation section while a carrier frequency is deviated by detecting that a DC component obtained from a loop filter of a synchronization tracking demodulator is within a prescribed range of level. CONSTITUTION:A signal phase-modulated such as a BPSK(biphase modulation) signal or a QPSK(quadrature modulation) signal is fed to an input terminal 21. An LPF 41 extracts a DC component of a signal from a loop filter 36 of a Costas loop demodulator 30 demodulating a phase modulation signal. Then a couple of voltage comparators 54, 55 and an AND circuit 58 detect whether or not the DC component is within a voltage range below processing upper limit level and over a lower limit level as a pseudo lock detection signal. Thus, the pseudo lock state in the mode specified by the carrier frequency is ensured and how much frequency offset is provided against the normal lock state is accurately detected.

Inventor: KUBOTA TAKAYUKI
IPC: F04B1/20
Filed: 1991-12-12
Abstract: PURPOSE:To prevent a presser plate from deforming by piston inertia force due to high speed rotation of a cylinder block. CONSTITUTION:On a presser plate 21, a tapered surface part 22 integrally formed toward the outer peripheral side from the central part by way of positioning it on one edge surface side positioned on the side of a cylinder block 9, and an taper angle beta of the tapered surface part 22 is formed so as to be roughly equal to the maximum inclination angle a of a swash plate 15. Consequently, as the presser plate 21 never makes contact with another edge surface 9B of the cylinder block 9 even in the case when the swash plate 15 is inclined up to the maximum inclination angle alpha, the maximum inclination angle alpha of the swash plate 15 does not need to be lessened, but by the tapered surface part 22, mechanical strength of the presser plate 21 is improved.
