Title: Dot printer
Inventor: MURAKAMI TADASHI
IPC: B41J9/48
Filed: 1983-09-30
Abstract: PURPOSE:To suppress the rebound phenomenon of printing wires by varying exciting power to make it smaller as the distance between the tip of the printing wire and a platen becomes smaller. CONSTITUTION:When an eccentric cam 5 undergoes an angular displacement and the interval between the tip 13a of a printing wire 13 and a platen 10 is largely set, the resistance value of a variable resistor 22 is small. When the tip 13a of the wire 13 is regulatively set by the eccentric cam 5 in such a way as to enable it to come near the platen 10, the resistance value of the resister 22 is greatly varied. Exciting current flowing in the coil 15 is therefore smaller as shown by a reference mark 2. As the interval between the tip 13a of the wire 13 and the platen 10 becomes smaller, the exciting power is less changed. The operating speed of the wire 13 is therefore reduced, and the returning speed of the wire 13 becomes smaller. The rebound phenomenon of the printing wire 13 can thus be suppressed.

IPC: G01S15/00
Filed: 1982-10-18
Abstract: PURPOSE:To measure the length of buried piping by sending an audible sound wave into the piping from an end and detecting the phase difference between in- piping sound pressure at the piping end and that nearly at the piping end. CONSTITUTION:A speaker 6 is connected to the end part 1a of the buried piping 1, and an oscillator 3 and an amplifier 5 are operated to generate an audible sine sound wave by the speaker 6. The frequency of the sine sound wave is varied to receive its sound pressure by microphones 7 and 8 at intervals, and a phase difference meter 11 detects the phase difference during resonance to know the esonance frequency through a frequency counter 4, finding the length of the pipe from the resonance frequency. Thus, the length of buried piping 1 is found indirectly at end parts 1a and 1b of the piping and even if there is corrosion, a different-diameter part, etc., in the middle of the piping 1, a secure less- disturbance measurement is taken with an about 1-5% error.

Abstract: PURPOSE:To enable momentary path exchange of signal light which is propagated in two ways by connecting optical fibers for optical signal transmission in a matrix mutually by using an optical circuit which is formed by a rare earth element added optical fiber and an optical filter. CONSTITUTION:When an excitation light source 5a is in a state of operation and 5c is in a state of stop, signal light from an optical fiber 1a is divided equally by an optical branching/coupling device 3a, and light entered an optical coupling device 4a is amplified by an erbium added fiber 2a and transmitted to an optical fiber 1b through an optical wavelength filter 6a. Meanwhile, light entered an optical coupling device 4c is damped by a fiber 2a and an optical signal is transmitted from the fiber 1a to 1b. A light source 5a is stopped and 5c are brought into an operation state; then, a signal inside the fiber 2a is damped and transmission from the fiber 1a to 1b is made unable; and, on the other hand, it is transmitted from the fiber 1a to 1c through the fiber 1a and transmission from 1b to 1c also becomes possible. Thereby, momentary path exchange of signal light transmitted to arbitrary two ways becomes possible.

Abstract: PURPOSE:To reduce centrifugal force, weight and size and to enable considerable increase in the number of revolutions of a spinner by constituting the spinner body in such a way that all the circumferential positions centroids over the entire axial length of the spinner body exist on a revolving shaft. CONSTITUTION:The position centroid of a straightening die device C0 exists on the revolving shaft O of a spinner when a straightening die 3 is mounted and fixed into a pushing hole 4 of which the axial line X of the guide path 31 for a wire rod is required to be set coaxially with the shaft O. The die 3 is displaced and positioned by screwing relatively oppositely tap bolts 6 and 6b screwed to the internal screw 5 of the hole 4 in the case of mounting and fixing said die into the hole 4 which is required to be set eccentrically at a prescribed value. The outside side faces of the arm parts 81, 81 of a U-shaped member of which the screw hole is screwed to the adjusting screw 602 of the bolt 6a are brought into contact with the plane wall 41 of the hole 4 and therefore the U-shaped member is regulated in turning and is displaced in the direction opposite from the screwing direction of the bolt 6a. The displacement of the U-shaped member acts as a balance weight and the position of centroid of the device C0 is thus maintained on the revolving shaft.
