Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To realize communication with a satisfactory CN ratio even in long distance transmission by varying a resonance frequency in the optical transmission line of an optical external modulator from a resonance frequency in an optical fiber transmission line. SOLUTION: Since video signal light is transmitted with a frequency different from the frequency of phase noise occurring in the optical fiber transmission line 2 and by a frequency band resonating in the resonance frequency band of the optical external modulator 5, the video carrier frequency of a first TV modulator 11 (11a) from the transmission side of a system is set to 218MHz, for example. The video carrier frequency of a second TV modulator 11 (11b) is set to 401MHz, for example, so as to operate the optical external modulators 5 (5a and 5b). Thus, a noise floor can be reduced by about 10dB compared to a conventional system in which the acoustic frequency of the optical fiber transmission line 2 does not differ from that of the optical external modulator 5 so as to improve the CN ratio.

Title: Microstrip antenna
Inventor: KUSHII YUUICHI
IPC: H01Q13/08
Filed: 1989-08-23
Abstract: PURPOSE:To obtain a desired resonance frequency even if the thickness or dielectric constant of a dielectric substrate or the diameter of a radiation conductor varies by forming a projection part or notch part at the outer peripheral edge part of the radiation conductor on the straight line connecting the center of the radiation conductor and a feed point. CONSTITUTION:The microstrip antenna which has the radiation conductor 13 and ground conductor 14 formed across the dielectric substrate 10 has the projection part 13a or notch part at the outer peripheral edge part of the radiation conductor 13 on the straight line connecting the center O of the radiation conductor 13 and the feed point P. Here, the resonance frequency is determined according to the size of the projection part 13 or notch part. Therefore, even if the thickness or dielectric constant of the dielectric substrate 10 or the diameter of the radiation conductor 13 varies owing to, for example, variance in manufacture, the resonance frequency can be adjusted by varying the size of the projection part 13a or cut part without varying the size of the radiation conductor 13. Consequently, even if the resonance frequency varies, a desired resonance frequency is obtained.

Title: Tracking servo-circuit
Inventor: OOTA FUMIO
IPC: G11B21/10
Filed: 1984-10-17
Abstract: PURPOSE:To reduce the turbulence of a tracking error after a tracking servo is reopened, by suppressing the variation of a high band component of a tracking error signal, in the opening period of a tracking servo-circuit. CONSTITUTION:A tracking error signal TE is supplied to a tracking coil 3 through the first phase compensating circuit 1 and the second phase compensating circuit 2, by which a tracking servo-circuit is formed. A switching transistor TrQ1 is usually in an on-state. In case a flaw, dust, etc. exist on a disk, the level of an information (RF) signal of a reproducing drops. As a result, the TrQ2 of a level detecting means 6 goes to an off-state, the TrQ1 also goes to an off-state, and the tracking servo-circuit is opened. In the course of this opening period, the variation (especially, a high band component) of the signal TE is suppressed by a high band suppressing means 5. Therefore, when the tracking servo-circuit is closed again, it is possible to shift comparatively smoothly to a normal tracking servo-state.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To hardly disconnect oil passages even in a pilot shaft of small diameter and to provide sufficient control responsiveness by providing at least two pairs of oil passages for driving a piston in the same direction on the piston and the pilot shaft. SOLUTION: A pilot shaft 14 is rotationally moved by a pilot driving device 12 from the condition in which conducting passages 42 are not communicated to an oil feed passage 38 and oil drain passage 40, and when the conducting passages 42 begin to communicate with the oil feed passage 38, the hydraulic oil pressure of a first space 28 is transmitted to a second space 30 through the oil feed passage 38 and the conducting passages 42, and a piston 16 is pushed on the extreme end side by the difference of pressure receiving area of the piston 16. Because the conducting passages 42 are inclined to the ridgeline of the shaft 14, the conducting passages 42 and the oil feed passage 38 return to the positional relation not communicating with each other and the piston is stopped.  In the case of large load, the shaft 14 is further rotationally moved, hydraulic oil flows in from the two conducting passages 42, and the driving force of the piston 16 becomes large. By reverse rotation of the shaft 14 the conducting passages 42 begin to communicate to the oil drain passage 40, and the piston 16 is moved on the base end side. In this way, the device can be provided with ring disconnection preventing action and sufficient control responsiveness in a small size.

Title: Image forming device
Inventor: HASEGAWA MAKOTO
IPC: G03G15/08
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress the reduction in image density while performing a proper toner density control according to the physical property change of a developer, and stably keep the image quality. SOLUTION: When a developer is in the initial state, the toner density control level for control of a P-sensor (reflection type photosensor) is changed to a control level lower than in general toner density control. Concretely, the development potential in the development of a P sensor pattern is changed from 300 V of timer to 380 V. Accordingly, the toner adhesion in development of a reference pattern is increased so that a higher toner density is intentionally wrong detected, consequently reducing the toner density. The photoreceptor charging potential is also controlled to prevent the reduction in image density.
