Patent JP-H03150731-A (JP)
Title: Objective lens driving device
Inventor: ADACHI YUKIO
IPC: G11B7/09
Filed: 1989-11-07
Abstract: PURPOSE:To reduce the occurrence of the twist and the tilt of a movable part and to ensure the stable writing/reading operations by providing a beam on the middle of a focusing leaf spring in its longitudinal direction to secure the connection between the focusing leaf springs opposite to each other. CONSTITUTION:The beams 7A and 7B are fixed through both ends of each of both beams approximately at the center between the focusing leaf springs 3A and 3C opposite to each other as well as between the focusing plate springs 3B and 3D respectively. Thus the connection is secured via both beams 7A and 7B between the springs 3A and 3B as well as the springs 3B and 3D respectively. Then the magnetic force is produced to move a variable part 2 in the focusing or tracking direction. Thus the synthetic force of both directions is applied to the part 2 so that the part 2 so that the part 2 is twisted or tilted. However the rigidity is extremely increased for those springs 3A - 3D which support the part 2 at four points with both beams 7A and 7B against the rolling direction. Thus, the part 2 is never twisted nor tilted.

Title: Gain controlling apparatus for ultrasonic flaw detector
Inventor: AOKI SHIGENORI
IPC: G01N29/22
Filed: 1991-10-09
Abstract: PURPOSE:To obtain a gain controlling apparatus for an ultrasonic flaw detector which can perform adequate flaw detection regardless of the state of the surface of a body under inspection, the presence or absence of temperature drift in a circuit and the like. CONSTITUTION:The ultrasonic-wave reflected signal from a probe 2 is stored in a waveform memory 6 through a receiving part 4, an A/D converter 5 and a gate circuit 16 and displayed on a liquid-crystal display part 14. A predetermined reference signal is taken out of the ultrasonic-wave reflected signals. Meanwhile, a specified level is set with respect to the maximum level, which can be displayed on the liquid-crystal display part. This level is compared with the reference signal. The gain of the receiving part 4 is adjusted based on the deviation between both values. Since the gain is automatically adjusted, the adequate flaw detection can be performed regardless of the peripheral conditions.

Abstract: PURPOSE:To reduce the effect of an undesired reflecting wave and to realize the surface acoustic wave filter with less ripple by arranging two long sides forming ends of a bus bar to be not in parallel with each other. CONSTITUTION:Ends 12a, 13a of a couple of bus bars 12, 13 prolonged to be close to each other in one interdigital transducer 4 have two long sides 25, 26 and two long sides 27, 28 respectively opposite to each other in their external appearance, and the two long sides 25, 26 and two long sides 27, 28 are formed to be not in parallel with each other so as to be close to each other as they approaches the end-most part. In such a case, a wave traveling toward the end 12a of the bus bar 12 takes a different path in the direction of propagation after, e.g. being reflected at the outside of the long side 25 from the direction of propagation after, e.g. being reflected at the inside of the long side 26. Thus, the reflected waves are attenuated, resulting in reduction of ripples.

IPC: H04Q9/14
Filed: 1990-10-26
Abstract: PURPOSE:To prevent the malfunction between devices by superposing a device discrimination code on a leader code to transmit them and taking out them by a decoding means and accepting a data code only at the time of signal coincidence. CONSTITUTION:When a device discrimination signal generated by a microcomputer 105 for remote control is written in an E<2>PROM 112, this signal passes a discrimination code generating circuit 111, which encodes the discrimination signal by PWM modulation, and is superposed on a carrier signal by a discrimination code superposing circuit 109. A transmission signal is superposed on this multiplexed carrier signal by a carrier superposing circuit 110, and an LED drive circuit 106 is driven by this signal, and it is radiated from an infrared LED 107 as an infrared transmission signal. It is inputted to a clock generating circuit 206, which generates a discrimination clock having the phase synchronized with that of the reception carrier and a carrier, and is inputted to a discrimination code decoder 207. It is compared with the device discrimination signal, and a coincidence output is sent to a microcomputer 205 for reception in the case of coincidence between both signals. Thus, the malfunction between device is prevented without a bad influence upon the present control system.

Title: Terminal calling type transmission equipment
Inventor: TADA FUMIHIKO
IPC: H04M11/00
Filed: 1985-12-23
Abstract: PURPOSE:To send a data with high reliability by allowing a center equipment to release a line when a reception data is normal to bring the state to the re-reception state at a fault and allowing a terminal equipment to apply re- transmission when no call tone is received after the data transmission thereby eliminating the need for the sending of a reply signal. CONSTITUTION:When a data transfer request takes place, a control section 38 of a terminal equipment 30 throws a changeover section 31 to the position of the equipment 30 and closes a closing section 33. When a call signal detection section 55 of a center equipment 50 detects a call signal, a control section 56 closes the closing section 51 to form the incoming state. The equipment 30 sends a data from a transmission section 37 in this state. When the equipment 50, when the data received by a reception section 51 is erroneous, keeps the closing section 51 continuously. When a call tone detection section 36 does not detect a call tone for a prescribed time after data transmission, the equipment 30 resends the data. The equipment 50 receives the data and when the data is normal, the closing section 51 is opened. Thus, a telephone line 40 is opened and the call tone is sent from an exchange 41 to the equipments 30 and 50.

Title: Scanner and its control method
Inventor: MIYASHITA MAMORU
IPC: H04N1/40
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a reduced image with a comparatively simple configuration in a film scanner provided with a linear image sensor moved at a prescribed speed. SOLUTION: The scanner is available of being set by the fine read mode and the rough read mode. In the case of a fine read mode A, every time the sensor moves in a lateral direction of a film, the storage/transfer output of signal charges is repeated. In the case of the read mode B, every time the sensor moves in the lateral direction of the film, storage of signal charges is repeated. The signal charge is transferred once with respect to two times of storage and the signal charges having been stored for that time are mixed. Thus, the number of pixels of the image in the lateral direction is halved without thinning processing.

Filed: 1991-10-08
Abstract: PURPOSE:To efficiently dope with doping gasses by the same laser beam by applying an electromagnetic energy to dissolve a reactive gas upon laser irradiation in a reactive gas atmosphere containing an impurity which gives one conductivity type. CONSTITUTION:A semiconductor chip 24 is irradiated with a laser beam 23 and doped with P under a PH3 atmosphere resulting from application and dissolution of an electromagnetic energy from a plane parallel electrode 29 in a vacuum chamber 21.
