IPC: H01F21/06
Filed: 1984-05-22
Abstract: PURPOSE:To prevent the generation of deterioration of efficiency such as the lowering of Q of a coil by a method wherein the upper hole diameter of the externally provided metal shielding case is multiplied by the prescribed multiplier, thereby enabling the metal shielding case to come closer to the coil. CONSTITUTION:A coil 11 is wound around on the upper part of a bobbin 12, and a terminal plate 13 is constituted by thermosetting resin. A core 14 is screw- fitted into the center hole of the bobbin 12, and it performs a vertical movement to the coil 11. A core supporting molded member 15 is covered on the terminal plate 13 whereon the bobbin 12 is coupled, and a magnetic shielding core 16 is inserted in and retained on the core supporting molded member. Besides, a metal shielding case 17 having an aperture 17a on the upper surface is coated on the whole surface. According to this constitution, the effect of the metal shielding case 17 is reduced by having the diameter of the upper aperture 17a of the metal shielding case 17 formed 1.1-1.4 times larger than the upper aperture part 16a of a magnetic shielding core 16.

Filed: 1989-04-21
Abstract: PURPOSE:To shorten a satellite catching time and to achieve reduction of labor by automatically detecting the posture angle of a stopped vehicle and calculating the relative direction of a satellite from the vehicle from the detected angle. CONSTITUTION:An azimuth sensor 8, a pitch sensor 9 and a roll sensor 10 for respectively detecting the azimuth angle, pitch angle and roll angle of a vehicle 1 are provided to the vehicle 1. At the stop time of the vehicle 1 stops, the posture angle of the vehicle is automatically detected and, from this posture angle and the angle data of a satellite in the absolute direction thereof, the angle data of the relative direction of the satellite looked from the vehicle is obtained. Then, the direction of an antenna 2 is set in the obtained relative direction. The actual posture of the vehicle 1 is added to this relative angle data and the antenna can be accurately directed in the direction of the satellite. The receiving intensity measured value obtained from a receiver 7 is compared with a reference value to discriminate whether the satellite is caught. The angle data in the relative direction is successively obtained corresponding to a discrimination result to control the direction of the antenna 2 and the satellite can be accurately caught.

Filed: 1993-04-28
Abstract: PURPOSE:To obtain a doped fiber, and a gain monitor employing it, in which emission of pumping light can be interrupted without requiring any special means for removing the leakage pumping light. CONSTITUTION:One example of a doped fiber, i.e., an erbium doped fiber 31, is constituted of a core 32, a clad 33, and a coating 34 applied thereabout.

Abstract: PURPOSE:To prevent the occurrence of missfeed, by a method wherein, by means of a brush engged with a paper feed roller under rotation, paper powder on the outer peripheral surface of the roller is removed to collect the powder in a collecting container. CONSTITUTION:When a paper feed roller 3 is rotated in the direction of an arrow mark so as to feed papers 1 on a tray 2, a brush 6 is rotated in the direction of an arrow mark with the aid of the roller 3, and the forward end of the brush 6 is brought into uniform contact with the whole peripheral surface of the roller 3 to sweep the paper powder adhered to the outer peripheral surface for removal. The removed paper powder is conveyed within a cylinder 8 in the direction of a collecting container through rotation of the spiral brush 6. When the paper 1 is delivered from the tray 2 by means of the paper feed roller 3, the paper powder adhered to the outer peripheral surface of the roller 3 is completely removed by the brush 6, and this causes the outer peripheral surface of the roller 3 to be always held in an optimum frictional state, and effectively prevents the occurrence of missfeed.

Title: Vortex generator/converter for vortex flowmeter
Inventor: ITO YOSHIHIRO
IPC: G01F1/32
Filed: 1994-04-05
Abstract: PURPOSE:To measure a low flow rate accurately regardless of the aperture of a flowmeter by inserting a vortex generator into a channel and a ball, oscillating while following up the vortex, in the rear of the vortex generator and then detecting oscillation of the ball floating in a fluid. CONSTITUTION:The vortex generator 1 generating vortex in proportion to the flow velocity and a ball 5 following up the movement of vortex 2 are inserted into a pipe 4 standing vertically. When the current velocity exceeds a predetermined level in a channel 7 having steeply increasing inner diameter, the ball 5 floats in the fluid. Since the ball 5 comes into contact only with the fluid, mechanical friction disappears. Consequently, the ball 5 oscillates accurately while following up the vortex 2 and when the oscillation is detected by means of a vortex detector 3, a low flow rate can be measured accurately through a simple apparatus.

Title: Image reader
Inventor: OGAMICHI TAKASHI
IPC: H04N1/401
Filed: 1991-04-10
Abstract: PURPOSE:To always stably and highly accurately execute shading correction without increasing cost by impressing a specific voltage as a reference voltage for an A/D conversion means. CONSTITUTION:The reading scanning of a white reference board 2 is executed and A/D conversion circuit 11 converts an image signal P into each digital signal value. A variable range detecting circuit 16 detects a maximum value and a minimum value in each line section from the diginal signal value. A CPU 10 allows a voltage generating circuit 14 to output the maximum and minimum voltage values. The minimum voltage value is impressed as the minus side reference voltage Vref (-) of the circuit 11 and the maximum voltage value is impressed as the plus side reference voltage Vref (+) through a selector 3. Since the level range of an analog image signal to be converted into a digital signal is narrowed to a minimum range to be required, the generation of quantizing errors is reduced. The number of quantizing bits is the same as a convensional method.

Filed: 1989-04-24
Abstract: PURPOSE:To make data storage quantity proper and to avoid a buffer error by interleaving a data with less importance or writing the data in duplicate in response to the state of overflow or underflow of a data buffer memory. CONSTITUTION:A silence detection section 41 monitors a digital voice input and detects the silence state depending whether a change in the data is within a prescribed value or less. When the silence state is consecutive and a silence data is stored in the data buffer 4, a control signal 42 is outputted to an address control 3. When the signal 42 is outputted from the control 3, a present write address is left as it is, and a readout address is set to a value being the subtraction of a prescribed value (e.g. a difference between the write address and the readout address when the readout is started at application of power) from the write address. Then the write and readout are restarted. Even when the difference between the write address and the readout address is fluctuated due to the difference between the write and read speed, the difference is set to a prescribed value to eliminate the buffer error.
