Patent JP-S5753720-A (JP)
Title: Optical actuator
Inventor: OOSHIMA MASAAKI
IPC: G12B1/02
Filed: 1980-09-17
Abstract: PURPOSE:To convert optical energy into the extent of the displacement of an apparatus directly without converting it into electric energy, by coupling an optical waveguide into a housing, composed partially of a bimetal plate. CONSTITUTION:One main surface of a housing 1 is made of a bimetal plate 2 and an optical fiber 3 is connected as an optical waveguide into the housing 1. The external wall of the housing is made of a light absorber 6, and the internal wall surface is made of a light reflector 7. When optical energy is introduced into the housing 1 by permitting laser beam to travel through the optical fiber 3, almost all optical energy is absorbed by the light absorber 8 and converted into thermal energy. The remaining optical energy which is not absorbed by the light absorber 8 directly is reflected repeatedly by the light reflector 7 as the internal wall surface of the housing 1 and absorbed by the light absorber 8 eventually to be converted into thermal energy.
Patent JP-S5919734-A (JP)
Title: Vibration absorbing device
Inventor: TERAGAKI TAKESHI
IPC: F16F9/10
Filed: 1982-07-26
Abstract: PURPOSE:To absorb vertical and horizontal vibrations by a method wherein the vertical vibrations are absorbed by using an oil and a coil spring in the titled device and the horizontal vibrations are absorbed by using the oil and a ball. CONSTITUTION:When a load is placed on a support table 38, the support table 38 and a cylinder 36 lower slightly and are supported in a floating condition. When a vibratory force is applied on the load in the vertical direction, the force is absorbed by the coil spring 39 and the oil 41. In this case, the oil in the space surrounded by the upper surface of a piston 35 and the inner surface of the cylinder 36 tends to go out from, or to enter, the space due to the vertical movements of the support table 38 but a throughhole 42 which forms a passage for the oil is small in diameter so that the entrance and exit of the oil with respect to the space become so slow as to make the oil absorb the vibrations of the load. Likewise, when a vibratory force is applied on the load in the horizontal direction, the ball 23 which is held between concave plates 19 and 21 rotates when it is subjected to the vibrations, to thereby absorb the vibrations. Further, even when the ball 23 tends to move within a cylindrical section formed between the concave plates 19 and 21, the movement of the ball is braked due to the viscosity of the oil 24. In addition, since a permanent magnet 17 attracts a magnetic ring plate 20, an upper receiving seat 15 does not get out of position.

Title: Optical information recording and reproducing device
Inventor: HOSHI HIROAKI
IPC: G11B7/24035
Filed: 1990-05-22
Abstract: PURPOSE:To eliminate the variation of an initial value by detecting the spatial nonuniformity of a phase with respect to a recording medium where information is recorded with the aid of utilizing an optical multiple interference effect and changing the refractive index of the medium based on the detected value so that initialization may be performed. CONSTITUTION:Multi-valued information is recorded by heating the medium 1 with the aid of light from a semiconductor laser for recording 2 and changing the refractive index (nM) thereof. The change of the refractive index is recorded by making it correspond to the change of the phase difference of etalon. On the other hand, the reproduction thereof is detected as the change of wavelength corresponding to the changing amount of the phase difference thereof. Then, the change of the refractive index (DELTAnM) which cancels the irregularity of thickness (DELTAd) is given by heating with the aid of a recording laser and the medium is initialized. Thus, the recording medium is initialized by detecting the spatial nonuniformity of the product of the refractive index and the thickness of the recording layer of the recording medium having the optical multiple interference effect and giving the change of the refractive index based on the detected result. Thus, the nonuniformity of the phase occurring caused by the various kinds of conditions when the recording medium is manufactured, secular change, erasing or the like is dissolved and the variation of the initial value is eliminated.

Title: Stabilizing power circuit
Inventor: TORII KENICHI
IPC: G05F1/56
Filed: 1978-10-24
Abstract: PURPOSE: To decrease a resistance ratio, to minimize variation in output voltage, and to obtain constitution suitable to IC-implementation by connecting a diode circuit between output terminals in series to an output voltage divider circuit.  
     CONSTITUTION: Transistors Tr51 and Tr52, operating as diodes with short circuits formed between bases and diodes, are connected foreward between output terminals 39a and 39b and also inserted into output voltage dividing resistances 42 and 43 in series. Variation in output voltage between output terminals 39a and 39b depends upon dispersion of each base-emitter voltage VBE of 1st and 2nd Trs 21 and 29 and that of VBE of Trs 51 and 52, but their variation directions are opposite each other for cancellation, so that variation in output voltage due to dispersion (mainly due to dispersion of VBE) of characteristics of a circuit element will be reduced. Further, temperature coefficients of Trs 21 and 22, and 51 and 52 can be canceled, so that the temperature coefficient of the output voltage can be made zero by a relatively-small resistance ratio.

Title: Malfunction preventing circuit for rectifier element with control pole
Inventor: ONDA KENICHI
IPC: H02M1/06
Filed: 1977-11-02
Abstract: PURPOSE: To constitute a malfunction preventing circuit which gives the steady and assured turn-off to GTO with reduced loss, by lowering dv/dt generated during the turn-off period and the spike voltage via two serial circuits of R and C.  
     CONSTITUTION: With reduction of forward current i p  of GTO3, the control for the voltage increase due to the charge current of C74 is carried out through charging of C72 which passed through R73 and C74 at the early time of turn-off since R71 R73 and C72  C74 are set respectively. When the charge voltage sum of C74 and C72 becomes identical to the voltage of power source 6, C74 discharges through R73 and 71. Thus, the voltage becomes zero. While C72 is charged up to the power voltage through R71 to reduce the voltage increase between the anode and cathode of GTO for that time. In this way, both the increase of dv/dt and the occurrence of spike voltage V p  can be reduced satisfactorily during the current reduction period.

Filed: 1983-07-20
Abstract: PURPOSE:To prevent dial misses by displaying office numbers-attached receiving station phone numbers when office numbers of the transmitting station in case office numbers fail to be inputted, in inputting receiving station phone numbers at the transmitting station, in the facsimile relaying transmitter. CONSTITUTION:When an operator keys-in phone numbers of the relaying station with a keyboard 19, the numbers are stored in an RAM22, and a CPU20 judges existence of out-of-town phone numbers among the phone numbers. If any, the CPU goes onto a relaying transmitting request operation immediately. If not any, the CPU judges the existence of the out-of-town numbers among the relaying station phone numbers, if does not locate, judges that phone numbers alone excluded from office numbers are inputted because a transmitting station, a relaying station and a receiving station all share the same out-of-town numbers, and then proceed onto a relaying transmission request operation. If there are out-of- town numbers among the relaying station phone numbers, the CPU reads out the receiving station phone numbers from an RAM22 as well as out-of-town numbers in the relaying transmitter, combines out-of-town numbers with receiving station by putting together, displays them on a display 18, and an operator checks and corrects them, watching the screen on the display.

Filed: 1989-05-24
Abstract: PURPOSE:To discriminate the discriminated signal of a composite input signal by updating and registering the minimum or maximum signal level of the composite input signal and using this level as a threshold level. CONSTITUTION:The composite video signal TVS1 which is digitized in synchronism with the rise of a reference signal LDS(1) is loaded in a register (I)21 with a load. Then a comparator 24 compares the value (minimum value data Dmin) D1 of the register (I)21 with the load with a next composite video signal TVS2 in synchronism with the rising of the reference signal LDS(2) and updates the minimum value data Dmin of the register (I)21 with the load when the minimum level of the composite video signal TVS1 is smaller. Consequently, the minimum value data Dmin corresponding to the minimum level which is updated and recorded is used as a slide level SL and an adder 23 can discriminates the horizontal synchronizing signal HS of the composite video signal TVS1.

Title: Active type vibration controller
Inventor: HAMABE TSUTOMU
IPC: F16F13/26
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To perform excellent vibration reduction control by adding an offset amount corresponding to the temperature change of an electromagnetic actuator to drive signals for driving the electromagnetic actuator. SOLUTION: Since the magnetic force of a permanent magnet 10C is changed corresponding to the temperature change of the electromagnetic actuator 10, a gap between the permanent magnet 10C and a magnetic path member 12 is changed. However, since the offset amount Δy for suppressing the change portion of the gap accompanying the change of the magnetic force is added to a filter coefficient calculated corresponding to LMS algorithm and outputted, the gap between the permanent magnet 10C and the magnetic path member 12 is turned to a prescribed gap and the gap is controlled corresponding to the drive signals from the state.  Thus, even in the case that the temperature change is generated, since the gap in an initial state between the permanent magnet 10C and the magnetic path member 12 is turned to a prescribed value and the gap to be a reference is kept fixed, control vibration is not changed corresponding to the temperature change.
