Title: Vibration isolator
Inventor: ISHIYAMA TATSURO
IPC: F16F13/14
Filed: 1991-04-25
Abstract: PURPOSE:To set either of two different vibration isolating characteristics without changing or adding parts with one vibration isolator. CONSTITUTION:At elastic body 30 has, on the outer circumferential part, a small recessed part 42 forming a second sub-liquid chamber 44 and a small recessed part 43 on the opposite side to a symmetry axis 11. A pressure receiving liquid chamber 36 is connected to the small recessed part 42 through a second communicating passage 54. In addition to a membrane 26 corresponding to the sub-liquid chamber 44, an outer cylinder 16 has a membrane 27 having a rigidity lower than the membrane 26 on the opposite side of the symmetry axis 11. When the elastic body 30 is inserted to the outer cylinder 16 and disposed thereon, the small recessed part 42 can be selectively conformed with either one of the membranes 26, 27 by changing the right and left sides to the asymmetry axis 11. When the case of conforming the membrane 26 with the small recessed part 42 is compared with the case of conforming the membrane 27 with the small recessed part 42, the frequency band in which a dynamic spring is reduced is closer to high frequency in a vibration isolator 10 in which the membrane 27 is conformed with the small recessed part.

Title: Communication disturbance device
Inventor: SUDO SACHIKO
IPC: G01S3/02
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To efficiently disturb communication by collectively disturbing a frequency of a TDMA communication wave used for time division multiple access communication. SOLUTION: The device is provided with a receiver 1 that receives a communication wave in existence in space, a frequency analyzer 2 that analyzes a frequency of a received wave received by the receiver 1, a time analyzer 3 that detects an incident time of the received wave for each frequency. When the received wave recognized to be split into time slots is detected at a single frequency band, the received wave is decided to be a TDMA communication wave. When the time analyzer 3 makes the discrimination above, a transmitter 4 collectively transmits a disturbing wave with the same frequency band as that of the TDMA communication wave.

Filed: 1984-05-15
Abstract: PURPOSE:To stabilize the supply of an ink material to a heating part, by providing an ink-holding mount with a mechanical vibrating element for transmitting vibration to an ink material, in a filmless thermal transfer recording system. CONSTITUTION:A heat-fusible semisolid or sublimable ink material 7 is contained in the holding mount 6.

In this case, since vibration is transmitted to the ink material 7 from the mechanical vibrating element 12 such as a piezoelectric element fitted to the mount 6, the ink material 7 is smoothly supplied to the heating part 10, the amount of the ink material 7 left in the holes 11 is reduced, and sharpness in printing is enhanced. The vibration frequency of the element 12 is suitably about several tens kHz.

IPC: G11B5/53
Filed: 1985-05-07
Abstract: PURPOSE:To draw the same head scanning tracks with those of normal reproduction during still picture recording by controlling the movement of rotary heads by using an electromechanical transducing element. CONSTITUTION:A head scanning track I when a magnetic tape 1 does not run has the same scanning track start position with a head scanning track II-2 in normal reproduction, but shifts in scanning track end position by one track pitch to the adjacent track right before it. In this case, a control means drives and controls the electromechanical transducing element, and a rotary head is displaced upwardly and gradually from its scanning track start position and then displaced at its scanning track end position by about one track pitch upwardly, i.e. to the adjacent track to be recorded next, so when an information signal is recorded while the magnetic tape 1 does not run, the recording track as the scanning track II-2 in normal reproduction is formed.

Abstract: PROBLEM TO BE SOLVED: To save trigger consuming energy without interfering with commutation and trigger a thyristor without retarding turn-off start timing of the thyristor, in such a circuit formation, for example, as current flowing through the thyristor commutate to the thyristor. SOLUTION: For example, in such a circuit formation mentioned above, this trigger device is provided with an on-off detecting means (a thyristor 5, a transistor 60 and so on) which detects the on-off signal of a thyristor 5 to output an detected on-off signal, and a trigger means (a transistor 60, a resistor 81 and so on) which is operated according to the detected on-off signal and continues to trigger a thyristor 15 as long as the on-off detecting means detects that the thyristor 5 is ON. It is thus possible to trigger the thyristor 15 together with triggering of the thyristor 5, continue to trigger the thyristor 15 while the thyristor 5 is ON, and stop triggering of the thyristor 15 together with commutation.

Abstract: PURPOSE:To form invariably optimum pictures as both a copying machine and a printer by varying development characteristics of a developing means according to the switching of an exposing means. CONSTITUTION:A copying machine and printer should vary the development characteristics when performing development by using the same developing device 4.

Thus, the development characteristics are changed by changing frequencies (f) and amplitude values Vpp of an alternating voltage. A blade 45 for preventing coating unevenness of a developer is held at the same potential with the sleeve 41.

Filed: 1982-06-05
Abstract: PURPOSE:To position accurately a scanner lens, by shifting finely a lens mount by means of a cam means after roughly the scanner lens by positioning a carriage. CONSTITUTION:When a magnification ratio selection button is pushed, a stepper motor 40 starts its revolutions. Then a carriage 20 starts to move to the left from the 2nd reduction position II. When a roll 36 falls into a positioning hollow 53RI of the 1st reduction position RI, the revolution of the motor 40 stops to position the carriage 20. In this case, a roll 32 is fitted to a cam fringe 57a. Cam fringes 57a and 58a are set with distance (l) between them in direction Y. A roll 32a oscillates a fine control lever 31 clockwise round a shaft 30 and shifts an end 26a of the shaft toward X. This gives a fine shift to a lens mount which is substantially unified with the end 26a.
