Title: Rotational mirror device for tracking
Inventor: CHATANI MASAHIKO
IPC: G11B7/09
Filed: 1991-06-25
Abstract: PURPOSE:To enable high-speed access by providing a flat spring, which movably and rotatably supports a mirror holding member and a reflection mirror holding member, and a permanent magnet and yoke by which the reflection mirror is rotated and moved. CONSTITUTION:By the flat spring forms, a narrow part 30a is formed, which allows a twist between an attached part 30b to the reflection mirror holding member 11 and an attached part 30c to the supporting member 16, and this narrow part allows the rotation of the reflection mirror. A yoke 14 and a permanent magnet 15 are attached to the member 16, and simultaneously, plural magnetic gaps with the same magnetic field direction are formed. When a rotational coil 13 is energized, a driving force to rotate a mirror 10 to the same direction is generated by each of the plural magnetic gaps. Also, when a translational driving coil 17 is energized, the driving force to translate the mirror 10 in the direction orthogonally crossed to the face of the mirror (the thickness direction of the spring 12) is generated by each of the plural magnetic gaps. Consequently, the deviation of an optical axis against an objective lens, which is attendant on the movement of a carriage, is eliminated.

Title: Flip-flop circuit
Inventor: SUZUKI YASOJI
IPC: H03K3/353
Filed: 1978-12-12
Abstract: PURPOSE:To attain high-speed operation, high integration and low power consumption by constituting an FF circuit by connecting the output of master FF composed  of two C-MOS inverters and transistors Tr to slave FF of similar elements. CONSTITUTION:Master FF consists of FF element 74 of C-MOS inverters 47 and  52, and Trs 53-54, and slave FF, composed of FF element 67 of C-MOS inverters  61 and 66, and Trs 68-71, is connected in series to master FF. Clock signal CK is applied to a fixed Tr gate and outputs Q's and Qs of slave FF are passed through inverters 72 and 73 to obtain outputs Q and Q', thereby constituting an FF circuit.  In an initial state, signal CK is ''0'' while outputs QM and QS of master FF are ''0''  and ''1'' respectively and when CK changes into ''1'', QM becomes ''1'' and QS is ''1''.  Once CK changes into ''0'', QS also changes into ''0''. In this constitution, an inverter of large Tr is unneeded since no out-of-phase signal is used, so that the advantage in low power consumption and high integration can be obtained. In addition, the response of variation in output with a clock is quick.

Inventor: URUFU BUUZE
IPC: H04N5/60
Filed: 1981-09-30
Abstract: The invention relates to a circuit for use in a receiver which can receive two-tone/stereo signals. This circuit is intended to make a choice between mono or stereo reproduction of signal A or of signal B and vice versa. The circuit comprises two bistable multivibrator circuits which are controlled by a common, user-operable switch and by characteristic signals which are derived from the characteristic frequencies relevant to the different types of programs. The control is such that when the switch is operated only one bistable multivibrator circuit can be changed over (namely the bistable multivibrator circuit associated with the relevant characteristic frequency received.) A logic circuit which is controlled by the bistable multivibrator circuit as well as by the characteristic signals operates a change-over switch for switching to the desired reproduction.

Title: Control condition in three point ground contact condition based upon shoe slip
Inventor: YAMAMOTO SHIGERU
IPC: E02F3/85
Filed: 1988-06-22
Abstract: PURPOSE:To eliminate the necessity of decelerating pedal operation by shifting the output mode of an engine from a basic mode to an elimination mode when the frequency of oscillation by which an amplitude of acceleration in a three point ground contact condition exceeds a value upon normal operation, exceeds a reference frequency. CONSTITUTION:A basic mode which is an engine output from which a high output power is cut in accordance with a soil and a lithology, is set in reference to an engine full output power curve shown in an engine traction v.s. speed chart, and is stored in memory in an output control system. Further, an acceleration during working operation is compared with an acceleration during basic mode so as to detect a three ground contact point condition. Further, detected is a frequency of oscillation which exceeds an amplitude of oscillation during normal operation in which the amplitude of acceleration takes a reference value in the above-mentioned condition. When this frequency of oscillation exceeds a reference frequency which has been set to a vehicle speed setting dial in accordance with a lithology, a signal is issued to shift the engine output power mode from the basic mode into an elimination mode. With this arrangement, it is possible to eliminate a three ground contact point condition without the necessity of depression of a decelerating pedal.
