Title: Frequency synthesizer
Inventor: MISAIZU KIMIHIDE
IPC: H03L7/23
Filed: 1985-05-20
Abstract: PURPOSE:To attain low noise by providing a phase locked loop circuit having the 1st and 2nd voltage controlled oscillators and using reference oscillators in common so as to convert the frequency. CONSTITUTION:The voltage controlled oscillator 15 constitutes the 1st phase locked loop including a variable frequency divider 14 and a phase comparator 13 and activated so as to be phase-locked with a signal through a 1/64 frequency divider 12 based on a reference crystal oscillator 10. In this case, the frequency of the voltage controlled oscillator 15 is changed by changing the frequency division ratio of the variable frequency divider 14 so as to attain the phase lock. Further, the reference frequency in the 2nd phase locked loop comprising a voltage controlled oscillator 25, a 1/350 frequency divider 23 and a phase comparator 22 is made identical to that of a reference crystal oscillator 10 of the 1st phase locked loop. Only a four-multiple device 29 is used as the multiplier circuit, the band is a band of a single frequency only, the constitution is easy and the number of times of multiple is less as a whole. Thus, phase4 noise and a spurious signal are decreased.

Patent JP-S61264309-A (JP)
Title: Autofocus device
Inventor: MAKINO HIROSHI
IPC: G02B7/09
Filed: 1985-05-20
Abstract: PURPOSE:To eliminate wrong focusing operation even if the panning of a camera causes a contrast value to vary by providing a lens drive safety means which moves a lens when the difference in contrast value is within a stable range for longer than a specific time. CONSTITUTION:A difference value detecting circuit 8 generates a reset signal unless the contract difference value of a difference circuit 4 is within its stable range + or -S and an operation control circuit 9 does not operates a motor control circuit 6 if a timer circuit 10 finishes clocking operation until a point T3 of time when a next reset signal is generated after the clocking operation is returned to a starting point, so a motor is not reversed. The motor, therefore, does not rotate while the difference value detecting circuit 8 generates the reset signal. The output signal L of the timer circuit 10 is applied to the operation control circuit 9 at a point TS of time which is a clocking time TS after a point T4 of time when the reset signal is ceased, and then the motor 5 is reversed to move the lens 1 to the peak value of the contrast value while the difference value of the difference circuit 4 is detected, thereby putting the lens closer to its in-focus state.

Abstract: PURPOSE:To reduce the cost of an fuel cell power generation system, by increasing the operation pressure of the system to a rated level while balancing the air pressure of an air supply blower and the outlet air pressure of an air processor with each other, to dispense with a compressor and a reservoir tank. CONSTITUTION:At the time of starting, air is fed from an air supply blower 6 to an auxiliary fuel unit 4, and the combustion exhaust gas of an auxiliary combustor 4 is fed to a high-pressure turbo-compressor 3 and a low-pressure turbo-compressor 1 through a mixer 5 to rotate the turbo-compressors. When the pressure of air discharged from the high-pressure turbo-compressor 3 and that of the air from the air supply blower 6 have thereafter balanced with each other so that their difference found out by a pressure difference detector 8 is smaller than a prescribed allowable value, this phenomenon is detected so that a controller 9 begins to operate, a control valve 7 is gradually opened, and the air discharged from the high-pressure turbo-compressor and that from the air supply blower are fed as burning air to the auxiliary combustor 4. After that, the operation of the air supply blower 6 is stopped so that the burning air for the auxiliary combustor 4 is fed only by the high-pressure turbo- compressor 3.

Title: Multibeam recording method
Inventor: YAMAZAKI SHUICHI
IPC: B41J2/44
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the defective information recording to a recording medium from occurring by eliminating the deviation of the rotational position of a stepping motor. SOLUTION: The beam pitch of a subscanning direction is adjusted by rotating a laser diode array being a beam generating means while using a stepping motor. Then, even whilst an information recording processing to the recording medium is performed, the coercive force of a rotational position is applied to the stepping motor by energizing the motor. As a result, at the time of the recording information to the recording medium, even though a device suffers from vibration or the like from surroundings, the stepping motor never generates the deviation of the rotational position.

Title: Sensitivity adjustor for moving coil type indicator
Inventor: SHIMIZU KOUICHIROU
IPC: G01R5/02
Filed: 1978-09-01
Abstract: PURPOSE: To make it possible to make the maximum scale of an indicator coincident with a pointer thereby to make the maximum sensitivity adjustment automatic by applying an alternate magnetic field to the permanent magnet of a moving coil type indicator thereby to reduce a preset quantity of magneticism.  
     CONSTITUTION: The standard signal of the maximum rated value of an indicator 1 having not been adjusted yet is fed out of a signal generator 5 on the basis of the control signal from a control device 6 and is fed as an input signal to the indicator 1. An indication detecting unit 3 detects the difference between the maximum scale and the pointer and feed out the same to the control device 6. This device 6 calculates the quantity of magneticism to be redeuced and fed to the permanent magnet of the indicator 1 and feeds the control signal on the basis of the calculated results to a magneticism reducing mechanism 4. This mechanism 4 feeds out an attenuating AC signal of a preset amplitude in response to the control signal from device 6. By reducing the magneticism in that way, the maximum scale can be made coincident with the pointer so that the maximum sensitiveness of the indicator 1 can be automatically adjusted.

Title: Knowing heat accumulation residue in heat accumulating tank
Inventor: HAMADA KAORU
IPC: F28D20/00
Filed: 1987-04-30
Abstract: PURPOSE:To know an exact heat accumulating residue by sampling the temperatures of latent heat accumulating capsules near the heating medium inlet and heating medium outlet and obtaining their average and calculating the calorie which has gone out of a heat accumulating tank by taking the average temperature as the variable of a three dimensional function and subtracting the result of the calculation from the total amount of heat accumulation which a heat accumulating tank has. CONSTITUTION:In general the heat capacity Q which a latent heat accumulating tank has can be expressed by a three dimensional function: Q=f(t)=At<3>+Bt<2>+Ct and D (A, B, C, D are constants) for the latent heat accumulating capsule temperature t. The temperature of the latent heat accumulating capsule has the largest variation near the heating medium inlet and outlet when the temperature giving and receiving for the latent heat accumulating capsule is considered, and at other positions the heat accumulating capsules are considered to have an intermediate variation to those variations. The temperature parameter to know the heat accumulation residue for the whole heat accumulating tank can be approximately known by knowing the average of the sum of the capsule temperatures at the above-mentioned positions. A temperature sensor is installed and the temperature information from this sensor is inputted to a sum average calculation circuit 4 and its output is inputted to a heat quantity calculation circuit, and the result thus obtained is compared by an approximate curve representing the state of being left to cool and a comparison circuit, and the heat accumulation residue is displayed digitally in Table 7.

Abstract: PURPOSE:To provide a charging apparatus in which the utilization efficiency of a DC power supply or the like inside the apparatus is high and which can quickly start the charging operation of a next charging battery. CONSTITUTION:A charging-current control means 56 supplies a charging current IC1 to one out of a plurality of charging batteries 12a, 12b, e.g. the charging battery 12a, from a charging-current output means 52. It reduces the charging current IC1 in a state that the charging last state of the charging battery 12a is detected by a charging-last-stage detection means 54.

In addition, simultaneously with a reduction in the charging current IC1 to the prescribed charging battery 12a, the charging operation of the other charging battery 12b is started at an early stage. As a result, also the time efficiency of the charging operation of the charging battery 12b can be obtained.
