Title: Operation control device of vehicle having internal combustion engine with variable number of actuating cylinders
Inventor: UEDA KATSUNORI
IPC: F02D41/02
Filed: 1994-10-05
Abstract: PURPOSE: To provide an operation control device by which transmission of a switching shock to a car body at cylinder switching time is restrained to the possible minimum level while securing a fuel consumption reducing effect by cylinder resting operation. CONSTITUTION: When an engine 1 is switched to cylinder resting operation from whole cylinder operation, after an ISC is opened and driven first of all, an ECU 26 outputs a cylinder resting signal SMD to a TCU 34. Then, the TCU 34 reduces the driving duty ratio of a solenoid valve 62, and reduces direct coupling pressure of a damper clutch 48. The ECU 26 also stops a valve moving mechanism after fuel injection of a resting cylinder is stopped when a prescribed time passes after the cylinder resting signal SMD is outputted. In this case, since the damper clutch 48 transfers to slip direct coupling or non-direct coupling, a switching shock is absorbed by a torque converter 31. After switching of cylinders is finished, the TCU 34 again restores the damper clutch 48 to ordinary control, and secures a fuel consumption reducing effect by cylinder resting operation.

Title: Transmitter for optically transmitting analog electric signal, and digital transmission system
Inventor: SCHLAG ERWIN
IPC: H04B10/43
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a receiver and to cope with high frequency by digitalizing an analog electric signal by ΔΣ modulation and having an electric-optical transducer for transducing the electric signal into an optical signal in a transmitter. SOLUTION: The ΔΣ transducer MOD of the transmitter SEN is composed of an integrator I, an amplifier 1 as a comparator, and a bistable element FF which is used in a 1-bit encoder and is clock-controlled. The integrator I is defined as a secondary low-pass filter of a ladder circuit network. An analog signal is stored in the integrator I along with a digital signal which is fed back, and after compared with a reference value in the amplifier 1, is digitalized in the bistable element FF. The element FF which is a D flip-flop applies an inverted output to the input of the integrator I for ΔΣ modulation. The electric- optical transducer EO is, for example, a laser diode which is directly modulated or a laser having an external electrooptical light modulator which is driven by the digitalized analog electric signal.

Title: Optical fiber coupler
Inventor: OBO SHIGERU
IPC: G02B6/28
Filed: 1985-10-30
Abstract: PURPOSE:To obtain an optical fiber coupler having high environment resistance by storing a part to be acted as an optical fiber coupler in a tube-like member consisting of the same material as the optical fiber and reducing the inner diameter of portions close to both the ends of the tube-like member until the inner periphery is contacted with the optical fiber to form a protecting member. CONSTITUTION:Optical fiber bundle 10, 11 are formed by previously thinning a single mode fiber by chemical etching, twisting and extending the thinned fiber simultaneously with thermal welding. Thereby, a branching/coupling part 20 of the optical fiber coupler is fairly thinned. A quartz tube 30 is the tube-like member to be a case for storing and protecting the optical fiber coupler and both the ends of the quartz tube are thinned as compared to the center. After inserting the optical fiber bundles 10, 11 into the quartz tube 30, the constricted parts on both the ends are heated and softened and connecting parts 40, 41 of the optical fiber bundles 10, 11 to the quartz tube 30 are formed by press contact. Thus, the branching/coupling part 20 of the thinned optical fiber bundles 10, 11 can be prevented from the application of thermal stress due to expansion/ cotraction based on temperature change and the environment resistance can be sufficiently improved.

Title: Press board for electric insulation
Inventor: OKANO FUMIHIRO
IPC: D21H13/24
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide compression resistance without impairing a low relative dielectric constant, high heat resistance, and an impregnating ability by forming filter paper with fibril resin fibers and wood pulp. SOLUTION: Properly beaten wood pulp and synthetic resins blended with it are used as main materials. The proper synthetic fibers are fibril polyarylate resin fibers having the nearly similar configuration to that of the beaten wood pulp. In the case of a board having the heat resistance of about the E type, the mixing ratio of the resin fibers and pulp is set to 30-100: 70-0wt.%. The resin fibers have the heat resistance of the H type or above, a low relative dielectric constant, and the fibrillation with the configuration similar to that of the beaten wood pulp, and the resin fibers can hold a good entangled state with the pulp.  When a press board thus obtained is used concurrently with a liquid or gas insulating material, no problem occurs on its impregnating ability, it has a relative dielectric constant lower than that of the conventional one, and it is excellent in heat resistance and compression resistance.

Title: Blade type cleaning device
Inventor: IIDA HARUKI
IPC: G03G21/10
Filed: 1987-09-29
Abstract: PURPOSE:To eliminate the scattering of toner sticking on nearby the edge of a blade from scattering around and to prevent the generation of an abnormal image and stain in equipment by putting a solenoid which drives the blade in gradual rising and falling operation through an electric or mechanical operation delay means. CONSTITUTION:A capacitor 5 is connected between the base of a transistor (TR) 6 and the ground and the base current of the TR 6 is increased gradually in response to a solenoid input signal (i), so a driving current supplied to a solenoid 4 increases gradually and the driving force of the solenoid 4 rises gradually as well. Namely, the solenoid output I rises gradually while requiring a prescribed time (t) because of the capacitor 5. When the solenoid output reaches a prescribed value, the output P of the main motor of a copying machine turns on and a photosensitive body 2 begins to rotate. Consequently, when the blade I contacts the photosensitive body 2, the solenoid is driven gradually, so a mechanical shock due to the contacting is suppressed extremely small and the scattering of the toner is suppressed.

A VTR 11 receives the signal from the camera 10, for example, an NTSC system video signal is generated, recorded to a video tape, etc., and at the time reproduction, the VTR 11 sends the video signal from the video tape to a monitor TV. On the other hand, when the switch 13 is changed over to the side 13b when one V period passes, and the video signal is outputted as the second field signal in one frame. As the result, the picture interlaced with the first and second fields is reproduced at the monitor TV.

Abstract: PURPOSE:To obtain a device which has high resolution and good color reproducibility and is less in the generation of a false signal by providing a means which generates a low-band luminance component for obtaining a luminance signal and a color difference signal from a main horizontal line. CONSTITUTION:The arrangement figure of a color separation filter shows respective horizontal lines by n1, n2,..., odd-numbered fields 01, 02,... indicate respective horizontal scanning lines in the odd-numbered fields, and horizontal lines n1 and n2 are processed simultaneously on, for example, the horizontal scanning lines 01, thereby obtaining the luminance signal and chrominance components. Even-numbered fields are also the same. An R filter and a B filter are arranged alternately at intervals of one horizontal line. The luminance signal is formed of W signals of two horizontal lines by said simultaneous processing of each horizontal line and the color filter arrangement, and the color difference signal is formed of the chrominance component and W signal of each horizontal line. Further, low-frequency luminance components of the luminance signal and color difference signal are formed from odd-numbered horizontal lines as main horizontal lines in odd-numbered fields and from even-numbered horizontal lines as main horizontal lines in even-numbered fields.
