Title: Compressor
Inventor: SAEKI MANABU
IPC: F04B27/10
Filed: 1994-07-01
Abstract: PURPOSE:To prevent the leakage of the coolant from a head part even when the head part of a screwing means is not sealed in a compressor to tighten a cylinder block and a housing by the screwing means. CONSTITUTION:A valve plate 17 is of the shape of avoiding bolt inserting holes 11a-11e. The surface on which a projected part 15 of a cylinder block is joined with a housing is sealed with a gasket. Because the circumferences of the bolt inserting holes 11a-11e are sealed with the gasket, the coolant is not leaked inside the bolt inserting holes 11a-11e even when the coolant from piston cylinders 7a-7e passes between a recessed part 13 and the valve plate 17. Thus, the head parts of bolts 12a-12e need not be sealed.

Abstract: PURPOSE:To enable more accurate water leak test without any switching setup between low-pressure and high-pressure tests, by comparing reductions in the pressure between the low-and high-pressure tests to judge on the propriety of work. CONSTITUTION:First, first - third opening/closing valves 7, 8 and 10 and a stop valve 5 are opened with an opening/closing valve controlling circuit to circulate water in a tank 2 through a pipeline 4.

After the water pressure in the boiler 6 settles at the inspection pressure near the test value, the stabilized inspection pressure is memorized into a memory register. On the other hand, the actually measured water pressure of the boiler 6 detected with a manometer 15 is sent to a corresponding buffer register. Then, the inspection value of the memory register and the actually measured pressure of the buffer register are inputted into a comparator circuit to make a comparison between the difference therebetween and the upper and lower limit set values and a signal is outputted indicating the propriety of the boiler 6 from the comparator circuit. Thus, more accurate water leak test can be performed.

Title: Correcting device for sound volume of electronic apparatus
Inventor: ICHIKAWA TERUO
IPC: G10L21/0208
Filed: 1980-10-28
Abstract: PURPOSE:To improve the degree of voice recognition, by extracting a signal having frequency components other than the sound band from the noise changing the frequency characteristics and the amplification factor of an electronic apparatus in accordance with the level of this signal. CONSTITUTION:Frequency components at the outside of the sound band are extracted from a signal, which is obtained from a microphone, by a band-stop filter. This signal is amplified and is rectified to obtain a control signal Vc. Meanwhile, the signal from the microphone is inputted to an ampplifier OA through a resistance R1 and a band-pass filter 28. The band-pass filter 28 consists of a resonance circuit and an FETQ1 operated as a variable resistor. When the noise is high, such control signal is given to the FETQ1 that the resistance of the FETQ1 becomes high; and as a result, the Q value of the resonator is raised, and the effect of elimination of frequency components at the outside of the sound band is enhanced. The control signal varies the gain of the amplifier OA to prevent the fluctuation of the output even for the change of the Q value.

Abstract: PURPOSE:To enable CSMA/DC and to improve throughput by transmitting test signals to a prescribed band during a test signal transmission period and deciding the collision of signals when any test signals excepting for the transmitted test signals are received during a pulse number check period. CONSTITUTION:When no test signal from another terminal is detected, a terminal to transmit communication data transmits plural pulse-shaped signals decided in advance having random time intervals or the test signals having the fixed value of the total sum of burst lengths within fixed time T1 before the transmission of the communication data. When any signals are detected during the period of transmitting no test signal within a fixed period T2 including the fixed period T1, the terminal transmitting the test signals judges that the signal collision is generated. When the previously decided number of pulse or the test signals exceeding the total burst length are received within the fixed period T2, the terminal transmitting no test signal judges that the signal collision is generated.
