Title: Liquid friction clutch
Inventor: OTOMARU PAIERU
IPC: F16D35/00
Filed: 1990-05-01
Abstract: PURPOSE: To enlarge an adjustable range by making the amount of a viscous liquid contained in a housing about equal to the volume of free spaces in a housing outside an inner blade, at a piston position corresponding to the largest blade spacing. CONSTITUTION: The amount of a viscous liquid in a housing 1 when inner and outer blades 5, 6 are spaced apart by the largest spacing is made about equal to the volume of free spaces in the housing 1 outside the inner blade 5 by an annular piston 8. Therefore when the blades 5, 6 are spaced apart by the largest spacing, the liquid ring 10 of the viscous liquid formed by a centrifugal force does not exist over the blades 5, 6 but enters between the blades 5, 6 as the spacing decreases. Therefore, operation without liquid friction and torque transmission is made possible and an adjustable range can be enlarged.

Title: Optical head
Inventor: YANAGAWA NAOHARU
IPC: G11B7/135
Filed: 1989-05-02
Abstract: PURPOSE:To increase the recording density of information by using an optical element to separate the light of an incident beam of light to an area separated from the optical axis, converging a luminous flux without having light in the vicinity of an optical axis with an objective lens and forming a spot of super high definition on a recording medium. CONSTITUTION:A conical prism 7 is provided at an optical path between an arranging prism 3 and the objective lens 5 to generate the super high definition phenomenon. A laser beam from a semiconductor laser 1 is shaped to the luminous flux with a circular cross-section at a collimator lens 2' and the shaping prism 3, and introduced to the conical prism 7. The conical prism 7 deforms the incident luminous flux and emits a cylindrical luminous flux whose outer diameter is magnified to the same degree as that of the objective lens 5 to the objective lens 5. When the cylindrical luminous flux without having the light in a center part is converged on the recording medium 6 with the objective lens 5, the super high definition phenomenon appears on the recording medium 6, thereby, the diameter D of a main lobe M goes to the one smaller than the diameter D' of an ordinary spot O without generating the super high definition phenomenon, and the signal of high frequency can be recorded with the spot of the main lobe M. In such a manner, the recording density of an optical disk can be increased.

Title: Ecl signal transmission circuit
Inventor: SATOU TATSUO
IPC: H03K19/086
Filed: 1983-06-21
Abstract: PURPOSE:To omit a power supply for termination by connecting one end of a termination resistor at the reception side of plural ECL circuits to a common line and connecting a capacitor between the common line and a ground potential. CONSTITUTION:An output of the ECL circuits 10 is connected respectively to a power supply VEE via a resistor 40. Further, an input to the ECL circuits 20 is grounded via the common line 60 and a capacitor 70. In the circuits 10, a terminal voltage V11 at an input terminal 11 is compared with a comparison voltage VREF, and when the voltage V11 is higher, a terminal voltage V12 at an output terminal 12 is brought into a high level V12H and when lower, the voltage V12 is brought into a low level V12L. Since the circuits 20 conduct similar operation, when lots of the circuits 20 exist, the number of circuits of low level state and the number of circuits in high level state are almost equal in terms of probability. Thus, even if the line 60 is connected to the power supply, the current flowing to/out of the power supply is zero and the potential of the line 60 is equal to an intermediate potential of high/level.

Title: Ink jet recording device
Inventor: WATANABE TAKASHI
IPC: B65H23/025
Filed: 1994-05-26
Abstract: PURPOSE:To convey recording paper without causing its deflection between recording means by forming a projection of a first roller in a direction in which a contact point with the recording paper moves outward in the lateral direction due to the rotation of the first roller. CONSTITUTION:A central part of recording paper supplied from a pair of register rollers to a printing unit in its lateral direction is sandwiched by the rollers between pulleys, both ends of the recording paper in the lateral direction are sandwiched by a conveyance belt 43 on the drive side and a conveyance belt 44 on the follow-up side, and the recording paper is conveyed in the P direction. At this time, a projection 830a of a deflection prevention roller 830 comes into contact with both ends of recording paper P1 in the lateral direction in a deflection prevention portion 810. Since peripheral speed of the deflection prevention roller 830 is slightly higher than the speed of the conveyance belt 43, the projection 830a moves outward in the lateral direction of the paper P1 while sliding on a surface of the paper P1. Tensile force is applied to the recording paper P1 in the (f) direction due to slide friction force. Consequently, it is possible to correct deflection of the paper P1.
