Title: Printing device and controlling method thereof
Inventor: KAWAGUCHI YUSHI
IPC: B41J29/46
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent printing operation from being started when normal printing is impossible by moving a printing head in the whole range of a printable area and detecting abnormality during movement of the printing head in initialization operation for detecting the absolute position in the printable area of the printing head. SOLUTION: When initialization operation is started, it is examined whether or not a home position detector generates a detection signal. When the detection signal is not generated, a printing head is moved in the left direction of a body by one step and this procedure (ST1-3) is repeated until the detection signal is generated. When the detection signal is generated, it is examined whether or not a step-out detector detects step-out. When step-out is detected, the function of a printing device is stopped (ST4-5). When step-out is not detected, the printing head is moved in the right direction by one step and the number of a driving step is examined. It is judged whether or not the printing head is positioned in the moving position of the rightmost end. When the printing head is not reached the moving position of the rightmost end, movement of the printing head is repeated (ST4-7).  When the printing head reaches the moving position of the rightmost end, initialization operation is normally finished (ST8).

Title: Fiber-optic interference-type sensor and method for detecting fiber-optic interference-type signal
Inventor: YAMANAKA TAKAYOSHI
IPC: G01H9/00
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To detect a physical signal, such as the impact, vibration signal, etc., applied to an optical signal with high sensitivity by using a sensor having a simple constitution and using a laser and a loop-like optical fiber. SOLUTION: The phase change caused between a clockwise propagated light ray and a counterclockwise propagated light ray in a loop-like optical fiber 3 by a physical change applied to the fiber 3 is detected, based on the signal outputted from a photoreceptor 224. Then part of the light rays propagated through the fiber 3 is taken out by means of an optical branching element 227 and the signal level of the taken-out light is detected by means of a signal level detecting means 228. In accordance with the signal level, the output level of the photoreceptor 224 is maintained at a prescribed value or higher by means of a light receiving level control means 230.  Thus the phase change caused between the clockwise propagated light ray A and counterclockwise propagated light ray B in the fiber 3 by the physical change applied to the fiber 3 is always accurately detected by compensating the line loss of the propagated light rays.

Title: Protective gear for distribution line
Inventor: OKAMURA MASAMI
IPC: H02H7/26
Filed: 1989-08-21
Abstract: PURPOSE:To enable reclosing in one-time accident interruption by installing accident detecting relays responding to an accident on the load side at the positions of each section switch and discriminating a section locking the closed circuit of a self-feeder breaker or the section switch by the operation or non- operation of the relays. CONSTITUTION:When an accident is generated in a section III, currents are flow through accident detecting relays 7, 8 in the directions of the arrows of solid lines and through a relay 9 in the direction of the arrow of a broken line, but currents flow through the relay 9 are reduced remarkably. Since the relays 7, 8 are operated and the relay 9 is not operated from the magnitude of the currents, a closing mechanism 10 is permitted to be closed by the operation of the relay 7 and a feeder breaker 2 is closed automatically. Likewise, a section switch 3 is closed automatically by the working of the relay 8. Since the relay 9 is not worked, however, a section switch 4 cannot be closed automatically because a closing mechanism 12 is locked. Accordingly, an accident section can be discriminated by one-time accident interruption.

Title: Two-wire type fully duplex modem
Inventor: KAKO TAKASHI
IPC: H04L69/40
Filed: 1992-08-12
Abstract: PURPOSE:To perform stable backup control by detecting line abnormality based on the number of converted points in descrambled secondary channel data per unit time concerning the MODEM for which the generation polynomial of scramble is different from the generation polynomial of descramble. CONSTITUTION:Data time divided into a main channel (Mch) and a secondary channel (Sch) are scrambled, afterwards, modulated and transmitted from a hybrid circuit 14 to a two-wire line. On the other hand, an echo component calculated from the scramble data is subtracted from the input signal of the circuit 14, demodulated, descranbled and divided into the data of the Mch and Sch later. Next, a line abnormality detection part 6 detects the number of converted points in the descrambled Sch data per unit time. Thus, when the echo component on the transmission side is not removed by the cut-off of the line, the number of converted points exceeds a prescribed number, and a line abnormality signal is outputted.
