Title: Pattern forming method of semiconductor device
Inventor: YOSHIKAWA KAZUNORI
IPC: H01L21/027
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a pattern forming method of a semiconductor device which can form a fine wiring pattern constituted of lamination structure, without increasing the number of processes. SOLUTION: A resist pattern 4 is formed on a first and a second conducting films 1, 2 which are laminated. After the second conducting film 2 is patterned, a first conducting film 1 is continuously patterned without eliminating a left resist pattern 4. The resist pattern 4 is completely eliminated by etching before the patterning of the first conducting film 1 is completed. After that, etching is continued by using the second conducting film 2 as a mask, and the patterning of the first conducting film 1 is completed. Thereby a process for ashing a resist pattern is eliminated, and a manufacturing process can be simplified.

Title: Transmission controller
Inventor: KOBAYASHI KAZUTOMO
IPC: H04L12/70
Filed: 1986-02-18
Abstract: PURPOSE:To improve throughput characteristics by forming a logical link for every partial circuit and performing error control corresponding to them. CONSTITUTION:Terminal interfaces 11 and 12 form a logical layer in a network layer and performs flow control and transmission confirmation corresponding to logical channels. Logical link control circuits 21-25 are connected corresponding to the logical channels of the terminal interface circuits 11 and 12 and perform transmission procedure, i.e., error control flow control, etc., among nodes. If the packet with a serial number B1 is sent to an opposite side by mistake, the opposite side sends back negative acknowledge(NAC) and packets of a logical link B are discarded thereafter until the packet with the serial number B1 is received. The transmission side when receiving the negative acknowledge(NAC) begins to resend packets from a packet with a serial number of the corresponding local link which is negated. Consequently, even a link which has a high transmission rate and is long in propagation delay like a satellite communication never causes the throughput and delay characteristics to deteriorate.

Title: Inductive load driving circuit
Inventor: TAROUMARU MAKOTO
IPC: B41J9/44
Filed: 1990-02-15
Abstract: PURPOSE:To efficiently so reduce a current of an inductive load as to rapidly fall by providing a capacitor to be charged by energy when a switching element is turned OFF, a charge detector for deciding whether the capacitor is charging or not, and a current control element for controlling a regenerative current from the capacitor to a DC power source. CONSTITUTION:Since a potential of a non-inverting input terminal 102 of a voltage comparator 10 is conducted at a rectifier 92 while a capacitor 5 is charging, it becomes substantially V+Vc, being higher than the voltage V of a non-inverting input terminal 101 connected to the positive side of a DC power source 1. That is, when the capacitor 5 is not charging, a voltage generated across an inductive load 21 becomes zero, the potential of the terminal 102 of the comparator 10 coincides with the potential V of the terminal 101, and the output of an output terminal 103 becomes zero. Accordingly, a transistor 11 is cut OFF. Therefore, when a switching element 31 is turned OFF, the load 21 charges the capacitor 5 in which its voltage is established through a rectifier 41, a rectifier 93 and a rectifier 92. Thus, the current of the load 2 is reduced in a short period.

Inventor: SESHIMO TATSUYA
IPC: B41J19/04
Filed: 1993-02-24
Abstract: PURPOSE:To form a printer capable of reducing noise by providing a weight to the region positioned between the drive pulley and carriage of a belt. CONSTITUTION:A weight 31 is provided at the position 3a of a belt 3 between the drive pulley 2 and carriage 5 of the belt 3 and a weight 32 is also provided to the position 3b of the belt 3 between the drive pulley 2 on the side where the carriage 5 is not attached and a follower pulley 4 of the belt 3. By this constitution, the vibration component transmitted to the position 3a between the drive pulley 2 and the carriage 5 in the vibration transmitted to the belt 3 from a monitor 1 through the drive pulley 2 is suppressed by the weight 31. Therefore, the vibration transmitted to the carriage 5 is also suppressed. As a result, the noise generated from the belt 3 and the carriage 5 is limited. Especially, in such a case that the carriage 5 has a box shape, noise is markedly increased but a resonance point can be shifted by attaching the weight 31 and noise can be markedly reduced.

Abstract: PURPOSE:To enable positioning with higher precision by performing affine transformation for transforming the coordinate values of a corresponding point into the coordinate values of a reference corresponding point so that the reference corresponding point matches the corresponding point of another radiation image by using a specific coefficient. CONSTITUTION:Respective corresponding points of one of radiation images are regarded as a reference corresponding point, the coefficient of the affine transformation expressed by an equation is found by a method of the least squares, and this coefficient is used to transform the coordinate values of the corresponding points into the coordinate values of the reference corresponding points so that the reference corresponding points match corresponding point of other radiation images. In the equation, U and V are the coordinates of the reference corresponding point, (x) and (y) the transformed coordinates of the corresponding points, (a), (b), (c), and (d) coefficients showing rotational movement corrections and enlargement or reduction rate corrections, and (e) and (f) coefficients showing parallel movement corrections. Consequently, all the corresponding points are so transformed as to approximate the reference corresponding point and the need to use a marker, etc., for the positioning is eliminated, so that the positioning with higher precision can be performed.

Filed: 1990-02-16
Abstract: PURPOSE:To switch and output to a different output port by making the output ports of a signal light different in accordance with a gain saturation state and a gain non-saturation state of light amplification generated in an optical directional coupling member. CONSTITUTION:In accordance with a gain saturation state and a gain non- saturation state of light amplification generated in an optical directional coupling member 3, output ports of a signal light are made different. When signal light intensity is a low level, no gain saturation is generated, therefore, a refractive index is not varied in the optical directional coupler 3, and accordingly, the signal light is taken out as an amplified output B, for instance, from the output port of a second optical fiber 2. On the other hand, when the signal light intensity is a high level, the gain saturation is generated and the refractive index is varied in the optical directional coupler 3, and switching of a propagation path of the signal light is generated, based on Kraemers-Kronig relations. In such a way, it is fetched as an amplified output A from an output port of a first optical fiber 1.
