Title: Device for detecting vertical and horizontal position of tone arm in linear tracking record player
Inventor: OGAWA KOUICHI
IPC: G11B3/38
Filed: 1982-12-28
Abstract: PURPOSE:To perform the operation of a tone arm smoothly and properly and to make the titled device compact by arranging four pieces of photodetecting elements on vertical and horizontal positions of the inside of one vertical wall of a recessed body and also arranging one light emitting element on proper position of the other vertical wall. CONSTITUTION:Phototransistors 1, 2, which are photodetecting elements, are arranged on a straight line l3 separated by a proper distance from the vertical center line l1 of a tone arm rotary shaft to the back in a plane Z including the vertical center line l1 and the horizontal center line l2 and parallel with the center line l1. If it is defined that the intermediate point between the phototransistors 1, 2 is 0, phototransistors 3, 4 are arranged on a straight line l4 passing the intermediate point 0 and perpendicular to the plane Z at equal intervals from the intermediate point 0. On the other hand, the light emitting diode 5 is arranged on a straight line l5 perpendicular to the straight lines l3, l4 and passing the intermediate point 0 in the vertical wall 7. Since a shutter plate 9 performs the same operation in accordance with the operation of the tone arm 8, the quantity of light made incident to the phototransistors 1-4 is changed, so that the position of the tone arm 8 can be detected precisely and easily.

Title: Method and equipment for scaling video picture
Inventor: KURISUTOFUAA DABURIYUU MARINOF
IPC: H04N9/64
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain a device and a method which acquire a high quality scaled image with a minimum buffer amount in real time. SOLUTION: A linear interpolator 26 and decimating finite impulse response(FIR) filter with constant coefficients may be used in various configurations to scale a still or moving color video image horizontally or vertically. For downscaling, the input pixel stream 24 is initially upscaled with an interpolator 26 by an upscaling factor of between one and two chosen so that the result can be subsequently downscaled with a decimation-by-power-of-two FIR filter to provide the desired final scaling. Upscaling is a special case accomplished by means of linear interpolation. Vertical and horizontal scaling may be performed with different, independent scaling factors.

Title: Data transfer system and data transfer method
Inventor: MIYAMOTO NAOYUKI
IPC: H04L12/50
Filed: 1994-09-26
Abstract: PURPOSE: To highly efficiently use a line without generating congestion by transferring data after transmitting data transmission conditions beforehand from a side for receiving the data to the side for transmitting the data. CONSTITUTION: A terminal 10 specifies the address of the terminal 40 and sends out a call setting message. An exchange 20 detects the call origination and a control part 27 obtains and outputs a transmission condition value for inhibiting the congestion from being generated in the incoming channel of the line B and stores it inside a call setting reception message. The exchange 20 returns the call setting reception message to the terminal 10. Thus, the data transmission conditions reach the control part 17 of the terminal 10 and the terminal 10 prepares data transmission corresponding to the data transmission conditions. The exchange 20 performs relay line call origination connection with the exchange 30, transmits the call setting message to the exchange 30 and performs the call origination. Similar return conditions are set between the exchange 30 and the terminal 40 as well, a response message from the terminal 40 is received and the terminals 10 and 40 can transmit and receive the data by the setting of a logical path between the exchanges 20 and 30.

Abstract: PURPOSE:To negate diamagnetic field due to generation of eddy current so as to lower misconvergence by running an electric current of a conductor loope in the direction so as to intensify the change of a magnetic field in a near area of a center beam passing hole. CONSTITUTION:Conductive wire 21 is brought to cross in two points and each side loope 40a, 40c is formed upside of a side beam passing hole and a center loope 40b is formed upside of a center beam passing hole. When horizontal deflecting magnetic field 30 is increased, eddy current 31a, 31b runs in the side plane of a shield cup 8 so as to inhibit the change. A diamagnetic field 32 is thus formed and a deflecting magnetic field weakens in a near area to a center beam passing hole 15b as compared to side beam passing holes 15a, 15c. On the other hand, due to the change of the magnetic field 30, electromotive force is generated in each loope, the change of magnetic fluxes passing the closed curved plane 40a, 40c become larger than that passing the closed curved plane 40b, an electric current 23 starts running in the whole of the loopes, and a magnetic field 22b in the direction to intensify the magnetic field 30 in a near area of the hole 15b is generated. As a result, the magnetic field in the near area to the hole 15b is prevented from weakening.
