Title: Scroll type fluid machinery
Inventor: HARASHIMA TOSHIKAZU
IPC: F04C18/02
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the sealing performance between the lap of a fixed scroll and the lap of a rotating scroll as well as to prevent scratching and abnormal wearing between the laps. SOLUTION: This scroll type fluid machinery is provided with a elastic coating layer 9 to peripheral surfaces 8B2 and 8B3 of a lap 8B of a rotating scroll 8. Further, a lubricating coating layer 10 is provided to cover the elastic coating layer 9.

This allows airtight sealing. Moreover, operation noises can be reduced and scratching and abnormal wearing are prevented by pressing the lap 8B of the rotating scroll 8 to the lap 2D of the fixed scroll 2.

IPC: G11B21/08
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To attain pose operation and search operation by moving light beams by N information tracks by supplying first and second control signals with N complete control cycles. SOLUTION: An optical-disk tracking controller 84 has two main operating modes controlled by the moving control signal 118 of a control signal generator 110. The first operating mode is generated when the moving control signal 118 supplies a signal, by which the control signal generator 110 is brought to a non-starting state. When the control signal generator 110 is brought to the non-starting state, the control signal generator 110 forms +1V in both a first control signal 112 and a second control signal 114. The optical-disk tracking controller 84 functions as the standard tracking servo loop of an optical-disk storage device by bringing the control signal generator 110 to the non-starting state. It is because both voltage values of the first and second control signals 112, 114 reach +1V.

Title: Signal level detector
Inventor: ISHII HIDEKAZU
IPC: H03G3/30
Filed: 1984-05-16
Abstract: PURPOSE:To suppress the occurrence of beat due to higher harmonic interference by stopping the operation of a signal level detecting circuit when the output of this circuit is lower than a reference voltage. CONSTITUTION:When the tuning frequency of a receiver reaches an accurate tuning frequency, a signal voltage is inputted to the input of a signal detecting amplifier 9. This signal voltage is amplified by an amplifier 9 and is detected by a signal detector 10, and therefore, a current is flowed to the base of an output transistor TR13, and the voltage of an output terminal 14 is reduced up to the saturation voltage of the TR13. As the result, the output is not taken out from a comparator 18, and the signal detecting amplifier 9 and the signal detector 10 are not operated. Thus, the occurrence of beat due to higher harmonic interference is suppressed.
