Patent JP-S6023053-A (JP)
Title: Printing apparatus
Inventor: MATSUSHITA HARUKAZU
IPC: B41J2/325
Filed: 1983-07-19
Abstract: PURPOSE:To realize high gradation reproducibility, by respectively dividing a large number of recording electrodes and return electrodes provided to the head of an electric heat transfer printer into a large number of groups, and appropriately combining said groups to perform matrix driving while bringing a specific number of the return electrodes in each group to a potentially floating state. CONSTITUTION:A large number of recording electrodes are linearily arranged to the head of a printer for performing thermal transfer of ink to paper by supplying a current to a sheet having a current supply layer and an ink layer and a large number of return electrode pairs 101-109 are arranged along the recording electrodes forming pairs at both sides thereof. In this case, return electrode pairs 101-109 are divided into M-groups each of which comprises i-numbers of adjacent return electrode pairs and, for example, when a selection signal electrode 301 is selected, data voltage is applied to two return electrodes 101, 102 and (i-2) numbers of the remaining electrodes 103-104 are floated. By this mechanism, because (i-2) numbers of floating electrodes 103-104 are present between the return electrodes 102, 105, a current therebetween can be suppressed as small as possible.

Title: Resonance controlling system for article transfer device
Inventor: NAGAYAMA AKIRA
IPC: G05B21/02
Filed: 1986-06-06
Abstract: PURPOSE:To stabilize a positioning control system by allowing a sampling frequency of a control part to coincide with a mechanical resonance frequency of a driving mechanism. CONSTITUTION:A mechanical resonance frequency component is controlled selectively from a position signal, by utilizing a fact that a transfer rate (a ratio of an output signal amplitude to an input signal amplitude) of a '0'-order holding circuit in a sampling control can be set to zero. That is, a transfer rate 31 in a sampling frequency of a '0'-order holding circuit 10 is zero, therefore, when the sampling frequency is allowed to coincide with a mechanical resonance frequency, the mechanical resonance frequency component can be attenuated selectively, and a positioning control system can be stabilized. For instance, by a modal analyzing device, etc., the mechanical resonance frequency of a driving mechanism is measured, and a generation frequency of a frequency adjustable type sampling signal generator 13 is adjusted so as to coincide with the mechanical resonance frequency.

IPC: B21D19/08
Filed: 1985-06-19
Abstract: PURPOSE:To reduce a metal die cost by enabling a metal die having a piece member assembled through an elastic member to be manufactured and used practically to a specific size. CONSTITUTION:A 1/2 inch size downward burring metal die is composed of a punch guide 6, punch body 7, a die body 8, a piece member 9, and a urethane spring 10. A blank W having a prepared hole for burring is set on the die body 8 and he punch guide 6 and the punch body 7 are moved down concurrently.

Title: Ink jet recording device
Inventor: SHIOTANI MAKOTO
IPC: B41J2/01
Filed: 1990-05-24
Abstract: PURPOSE:To obtain high density gradation/high definition pixels by specificially controlling a dot diameter and a dot density when data is recorded using on-demand and multi-droplet ink jet recording technique. CONSTITUTION:A following droplet 4 is discharged by targeting at a point within a range of from 1/2 the diameter of an earlier discharged ink droplet to inwardly from the dot circumference by a standard deviation (sigma) of the shake value of the droplet that hits a medium for recording. Subsequently, a sufficiently high density gradation and high definition image is obtained. That is, if the ink droplet is discharged so that the average value of a distance (delta) between the adjacent points where adjoining ink droplets hit a medium for recording equal to the diameter of a dot when the ink droplet hits the medium/2-sigma, it is estimated that about 86% of the total number of dots hits a point within a range of 1/2 or smaller of the diameter of a dot when the ink droplet hits the medium, assuming that the droplets which indicate a hitting shake might be regularly distributed. In addition, the majority of the remaining 14% of dots hits a point which is quite close to 1/2 the diameter of the dot when the ink droplet hits the medium. Therefore, there is almost no change in the dot area or the dot density as a whole. As a result, a sufficiently high density gradation and high definition image is obtained.
