Title: Phase-locked loop circuit
Inventor: KANAYAMA KEISUKE
IPC: H03L7/10
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To attain high speed phase synchronization locking, with respect to a phase locked loop(PLL) that synchronizes the phase of the output signal of a voltage controlled oscillator with the phase of an input signal. SOLUTION: A phase comparator 5 compares the phase of an input signal with the phase of a frequency dividing output signal which results from frequency-dividing the output of a voltage-controlled oscillator 1 with a frequency divider 6, and an output signal from the phase comparator is used for the control voltage of the voltage-controlled oscillator 1 in the phase-locked loop.  The phase-locked loop circuit is provided with a lock control section 8 that controls 1st and 2nd changeover circuits 2, 3 in such a way that whether or not a frequency of an input signal is higher or lower than the center frequency is discriminated in the locking, a control voltage VCw with a lower limit frequency is selected when it is higher, or a control voltage VCh with a higher limit frequency is selected when it is lower, and the selected control voltage is given to the voltage-controlled oscillation 1 in place of the control voltage from the loop filter 4.

Title: Segment editing/output system
Inventor: YAMAGUCHI EIJI
IPC: G06F11/34
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the output of undesired segments and to improve the operability in the system by designating the desired segments via a parameter file. CONSTITUTION:If a transaction processing system has the abnormality, the control is shifted to a segment editing/output system. This system transfers the control to a parameter reading means 11.

The means 12 analyzes the desired segments out of the record and stores these segments in a segment control table 16. A segment deciding means 13 decides whether the segments should be edited and outputted or not by reference to the table 16. If so, the corresponding segment is taken out of the table 16 and given to a segment editing/output means 14. Thus the means 14 reads the relevant segment name out of a segment file 17 to edit and output the corresponding segment.

Title: Vibration damping device of rotary compressor
Inventor: KAMITSUJI TOSHIO
IPC: F04C29/06
Filed: 1989-03-23
Abstract: PURPOSE:To obtain a sufficient vibration damping effect even if the rotating frequency is changed by fixing one end part of a tension coil spring having arm parts extending at right angles to the winding central axis from the both end parts of the winding to a fixture for a sealed case having a compressing element part and an electric motor part contained therein, and the other end part to an inertial body. CONSTITUTION:A sealed case 2 is vibrated by the operation of a compressor, but by vibrating the inertial body 15 of a dynamic vibration reducer 14 in the opposite phase to the vibration of the sealed case 2, the vibration of the sealed case 2 is damped. A connecting part 16 is formed of a tension coil spring having initial tension and arm parts 16a, 16b. When a space is formed between windings, bending rigidity is changed, and the peak width of the natural vibration of the dynamic vibration reducer 14 is widened, causing damping effect. Therefore, the peak width of the maximum damping frequency is widened, and vibration damping effect can be obtained in a wide frequency band. By fixing the protruding part 17a of a fixture 17 and the projection part 15a of the inertial body 15 to both end parts 16a, 16c of the connecting part 16, the natural frequency of the dynamic vibration reducer 14 can be stabilized.

Title: Gas and liquid permeable carbon electrode for electrolysis of aqueous solution
Inventor: TORIKAI EIICHI
IPC: C25B11/12
Filed: 1986-03-28
Abstract: PURPOSE:To improve the gas and liq. permeability and to provide high mechanical strength and cushioning action by specifying the amount of expanded graphite in an electrode forming base material and the diameter of the pores in a molded body. CONSTITUTION:A carbonaceous material other than graphite is added to 20-95% expanded graphite and they are kneaded, molded, dried and hardened. The resulting molded body is baked to form a carbon electrode for the electrolysis of an aqueous soln. The electrode has pores of 0.05-10mum diameter. When the electrode is used after it is brought into press contact with an electrode- membrane joined body, the electrode can be well adhered without damaging the membrane because of the proper cushioning action. Since the electrode has satisfactory gas and liq. permeability, the increase of cell resistance due to defective gas/liq. distribution is prevented.
