Title: Intake control device of engine
Inventor: AJIKI YOSHIO
IPC: F02B27/02
Filed: 1992-06-22
Abstract: PURPOSE:To provide an engine with capability of high torque operation in a wide range including the low to high speed by lessening the effective opening area of a intake valve hole in a certain low speed operating range using a valve operation changing mechanism, and prolonging or shortening the intake passage in another range with low speed operation. CONSTITUTION:A valve system 2 is equipped with a valve operation changing mechanism 6, and when a working oil is supplied from an oil path 5 a first rocker arm A1, etc., are coupled in a single piece, while they are turned possible to make relative angular displacement when the working oil is released. In the former condition, first intake valve V1, etc., open and shut according to the shapeof a high speed cam 3, while in the latter condition, the first intake valve V1 opens and shuts with rotation of a cam C1 for low speed operation and the effective opening area becomes small. In other range with low speed operation, the intake passage WL for low speed operation is made longer than the intake passage WH for high speed operation by a selector valve 20 of a path constitution altering means. Thus high torque is obtained in a wide range including low to high speed.

Title: Measuring method of optical fiber of distribution type
Inventor: FUTAJIMA HIDEAKI
IPC: G01K11/12
Filed: 1990-06-21
Abstract: PURPOSE:To measure the physical quantity along an optical fiber with higher sensitivity by monitoring the speckle pattern of a back scattering light in the optical fiber which is a sensor and detecting the intensity of the light at a specific point of the pattern. CONSTITUTION:An optical pulse from a light source 1 enters an optical fiber 3 via an optical directional coupler 2. A back scattering light is returned from each part of the fiber 3. The speckle pattern of the back scattering light guided to the side of a photodetecting circuit 4 by the coupler 2 is monitored to detect the intensity of light at a point B. The spatial normalization is performed by dividing the intensity of light at the point B by that of the whole speckle pattern. If a distortion is added to a point A of the fiber 3, the propagating state of the light at the point A is changed and therefore the speckle pattern formed by the back scattering light passing through the point A is changed as well. As a consequence, the intensity of light after a time tA corresponding to the point A is changed. Accordingly, if the change of the speckle pattern resulting from the change of an external factor is monitored, it becomes possible to detect the presence or absence of the minute change of the external factor.

IPC: G01R23/09
Filed: 1979-12-14
Abstract: PURPOSE:To realize generation of an analog signal having a specified weight and simplify the constitution of a frequency-voltage converter, by securing a combination between a shift register and an exclusive OR circuit. CONSTITUTION:The frequency input F-in stored in the shift register 6 is output through the terminals Q1-Q5 in synchronizig with the clock pulse CLOCK. These outputs are applied to the exclusive OR circuit 7 to obtain the analog signal P at the output. The weight value of the signal P is proportional to the bit size of the register 6 and the driving voltage VCC and adversely proportional to the frequency of the CLOCK. The signal P is smoothed by the filter 5 and then converted into the voltage signal.

Title: Reduction gear for elevator
Inventor: WATANABE HIDENORI
IPC: B66B1/30
Filed: 1988-07-01
Abstract: PURPOSE:To prevent comfortableness to ride in a cage from deteriorating caused by backlash of gears by using an electric field responsive viscous material as the lubricant for a reduction gear and applying an electric field to the electric field responsive viscous material to increase its viscosity when tooth contact of the gear is switched. CONSTITUTION:This reduction gear uses an electric field responsive viscous material (hereinafter called ER fluid) 40, whose viscosity changes corresponding to intensity of an electric field, as the lubricant for gears 11B to 11J, and the electric field is applied to the ER fluid 40 by detecting when tooth contact is switched of the gears 11B to 11J. That is, when no electric charge is present in electrodes 41, 42, the ER fluid 40 is electrically neutral, but when voltage V is applied across the electrodes 41, 42, a positive electric charge is allowed to flow into the positive electrode 41. On the contrary, a negative electric charge is allowed to flow into the negative electrode 42. Under this condition obtained, grains are connected in a chain state. Gravitational force acts on the electric charge, and this gravitational force is a source of generating viscosity of the ER fluid 40 obtaining shearing resistance. Accordingly, comfortableness to ride in a cage can be prevented from deteriorating due to backlash of the gear.
