IPC: G02B26/10
Filed: 1980-07-18
Abstract: PURPOSE:To eliminate troubles due to a collision of a rocking member by holding the rocking member by a holding means without play when no electric power is supplied to the rocking mirror driver of an electrophotographic copier. CONSTITUTION:The figures show the unlocked state and locked state of a rocking member such as a mirror 1. Since electric power is fed to one of an arc-shaped motor 5, an electromagnet 14 and a plunger 24 while an rocking mirror driver is transported, a connecting pin 18, i.e., base end sides of retaining members 16A and 16B are lifted by the retaining strength of a coil spring 21, and consequently the free ends of the members 16A and 16B are lowered to press against the top surface of the mirror 1 through a cushion 22. Therefore, the mirror 1 is held not to rock between a home position H and a return position R, so that an arm 4 is separated from the electromagnet 14 and a needle 7 is also separated from a stator 6.

Title: Excessive-pressure protecting mechanism of differential-pressure transmitter
Inventor: FUKUHARA SATOSHI
IPC: G01L19/06
Filed: 1991-04-26
Abstract: PURPOSE:To protect the excessive pressure of a differential-pressure transmitter by outputting the differential pressure between the first pressure, which is applied to a recess part, and the second pressure, which is applied to the other side of a single- crystal substrate and obtained through a pressure guiding hole, into a sensor part. CONSTITUTION:When a low pressure PL is applied to a sealing diaphragm 57, the pressure is applied on sealed liquid 73 in an excessive-pressure protecting mechanism 23 and also applied to a recess part 38. Meanwhile, when a high pressure PH is applied to a sealing diaphragm 31, the pressure is applied to sealed liquid 44 in an excessive- pressure protecting mechanism 22 and also applied to a recess part 64. When the pressure difference DELTAP between the low pressure PL and the high pressure PH is in the specified range, valves 69 and 43 do not close through holes 66 and 32. Therefore, the pressure difference DELTAP is applied to a thin part 52 of a sensor part 26, and the corresponding signal is outputted. When the high pressure PH is applied, a coupling part 42 closes a through hole 40 and prevents the excessive pressure for the sensor part 26. When the excessive pressure is applied to the side of the low pressure PL, the valve 69 closes the through hole 66, and the transmission of the excessive pressure to the sensor part 26 is prevented.

Title: Ultrasonic radiating device for treatment
Inventor: WADA TOMOMOTO
IPC: A61F7/00
Filed: 1989-04-17
Abstract: PURPOSE:To improve irregular ultrasonic energy distribution caused by mutual interference of each ultrasonic beam and reduce standing waves generated near a reflector when a plurality of ultrasonic beams are entered into a living body by imparting a minute frequency difference to the ultrasonic waves generated from each ultrasonic transducer. CONSTITUTION:When ultrasonic transducers 5-1, 5-2 are driven at single frequencies, the vertical axis shows ultrasonic energy, and the lateral axis shows distance, and these frequencies are equal to each other, a high peak is obtained in the center part where the phases of both ultrasonic beams are regularly coincident. When the frequencies are minutely different, however, the energy is gently distributed as the phase coincidence point is regularly moved. A marker is simultaneously projected on the center of a tomographic image, and the focusing point of an ultrasonic irradiator 1 is regulated to such a positional relation as overlapping this marker. An operator moves the ultrasonic irradiator 1 by a button on an operating part 20 while seeing the tomographic image and searches the affected part. When the affected part is found, the marker on the tomographic image is operated to be finally set to the affected part, and the affected part is irradiated with ultrasonic waves from the ultrasonic irradiator 1.

Abstract: PURPOSE:To reduce the gap between a casting and iron cores and to reduce the size and weight of a rotating field type electromagnetic stirrer, by disposing an inductor core into a polygonal shape, and disposing independent annular windings for each of the core pieces. CONSTITUTION:An inductor 2 of a polygonal shape is provided around a casting 1. The inductor is formed into the polygonal shape of iron core pieces 3a-3d. Plural grooves 8 in flow directions of castings are provided on the inside circumferential side of the cores 3, and annular windings 8 which wind the iron core pieces and are embedded in the groove 8a on the inside circumferential side of the iron cores are provided independently to each of the pieces 3a-3d of the iron cores 3. The windings 8 are so connected that the cores 3a, 3c and 3b, 3d have reversed polarities and the same phase, then two-phase AC current is flowed therein. Since the inductor 2 is formed into the polygonal shape along the casting 1, a gap 6 can be made smaller and the magnetomotive force required for the excitation of the gap 6 is decreased. The electromagnetic stirrer is thus made smaller in size and weight.

Filed: 1989-04-18
Abstract: PURPOSE:To superpose two image recording material uniformly one over the other without wrinkling and to prevent an image irregularity from being generated by carrying the two image recording materials synchronizing with each other at a carrying speed slower than the rotary moving speed of the outer peripheral surface of a rotary drum. CONSTITUTION:The two image recording materials are carried by clamping and carrying rollers 114 synchronizing with each other through different paths and sent in between a superposing roller 120 and the rotary drum 116. The image recording materials which are thus sent in are clamped and superposed on over the other in order by the superposing roller 120 and rotary drum 116 and wound around the outer periphery of the rotary drum 116 while superposed one over the other. At this time, the outer peripheral surface of the rotary drum 116 rotates and moves at the rotary moving speed faster than the conveying speed by the clamping and carrying rollers 114, so the image recording materials do not slacken after their head end parts are clamped by the rotary drum 116 and superposing roller 10. Consequently, each image recording material is superposed uniformly without wrinkling and no image irregularity is generated.
