Title: Magnetic recording and reproducing device
Inventor: WATANABE KATSUYUKI
IPC: G11B20/22
Filed: 1984-12-07
Abstract: PURPOSE:To improve the S/N of a regenerative signal by sufficiently suppressing crosstalk between rotary transformers connected to respective magnetic heads in case of adopting an overlap recording system, an ATF system or an SP/LP mode selecting system. CONSTITUTION:A regenerative signal of a magnetic head Y1 for an LP mode is supplied to the (a) sides of change-over switches 25c, 25d through a rotary transformer 23c and an amplifier 5c and a regenerative signal of a magnetic head Y2 for the LP mode is supplied to the (b) sides of the switches 25c, 25d through a rotary transformer 23d and an amplifier 5d. The phase of a head switching signal t2 outputted from a servo circuit 9 is changed by the difference of positions between a couple of the SP mode magnetic heads and a couple of LP mode magnetic heads. Thus, a PCM sound signal reproduced by the LP mode magnetic heads Y1, Y2 is obtained from the switch 25c and supplied to a PCM processor 28 through a change-over switch 27 and the demodulated sound signal is obtained from an output terminal 29.

IPC: H02P3/06
Filed: 1993-10-15
Abstract: PURPOSE:To make a user recognize an abnormality and move a window glass to the vicinity of an optional position when the abnormality occurs on the rotation signal. CONSTITUTION:When an abnormality occurs on the rotation signal from a rotation sensor 20 during the drive of a motor 14, a microcomputer 16 stops the motor 14 when a prescribed time elapses after the abnormality of the rotation signal is detected. A window glass is not stopped immediately by the abnormality of the rotation signal, and the motor 14 is driven for at least a prescribed time after an operation switch 12 is turned on. Even if the abnormality occurs on the rotation signal while the window glass is opened, the window glass can be moved to the vicinity of an optional position (e.g. fully closed position) then stopped when the operation switch 12 is repeatedly turned on and off.

Title: Character plotting processor
Inventor: MAKI YASUNORI
IPC: G06T11/40
Filed: 1989-10-05
Abstract: PURPOSE:To normally perform painting-out even when the contour of character or mark becomes on point by providing an arithmetic device for checking that one or more contours constituting the character or the mark are an identical coordinate point from the coordinate of starting plotting to the last. CONSTITUTION:An interpolation arithmetic part 11 sets a flip-flop in it when the coordinate value of starting the contour of character or mark arrives. Then, it calculates the coordinate value of the contour and resets the flip-flop when the coordinate value different from the coordinate value of starting the contour arrives. Therefore, the set state of the flip-flog is held as long as the identical coordinate value arrives. At the time of finishing the plotting of the contour in a state where the flip-flop is set, the corresponding contour lines are superposed on one point is informed from the interpolation arithmetic part 11 to a contour plotting part 15 through a signal line 20. The contour plotting part 15 acts to put a black level on the coordinate value. Thus, it is unnecessary to consider that the contour of character or mark does not become one point.

Title: Remote monitor/controller
Inventor: SAKUMA YUICHI
IPC: H02J13/00
Filed: 1989-10-05
Abstract: PURPOSE:To obtain time information without increasing the volume of information communicated between remote monitors/controllers by providing a time information adder for adding a time, obtained by subtracting an inherent time necessary for reaching to a remote monitor/controller in a control station from current computor time, to information transmitted from a station to be controlled. CONSTITUTION:The time required for transmission of information from a machine to be monitored/controlled to a control station has an approximately constant inherent value which is determined for each facing, status change signal. A remote monitor/ controller B in a control station receives the time of a CPU clock 9 in a computor C with predetermined period. When some information is transmitted from a station to be controlled to the control station, a time information adder 10 reads out the inherent time from a memory section 11 if the transmitted information requires the occurring time. The information is then transmitted to the computor C with time information, obtained by subtracting the inherent time from the computor time of the CPU clock 9, being added. By such arrangement, time information can be obtained without increasing the volume of information communicated between remote monitors/ controllers A, B.

Title: Liquid level monitoring apparatus
Inventor: IKEHARA TADASHI
IPC: G01F23/28
Filed: 1986-10-30
Abstract: PURPOSE:To monitor a liquid level accurately and certainly, by emitting a laser beam having a beam path inclined with respect to a predetermined liquid level surface and detecting the change in the beam patch of laser beam generated by the refraction on the surface of a liquid. CONSTITUTION:When the level of a liquid 11 is below a predetermined value and a beam receiving part 15 is exposed above the surface of the liquid, the laser beam 13 from a laser beam emitting part 14 is incident on the part 15. When the liquid level rises above the predetermined one and the part 15 is positioned under the surface of the liquid, the laser beam 13 is refracted on the surface of the liquid 11 and not incident on the part 15. Therefore, on the basis of the change in the signal from the part 15 measured in a measuring part 17, it can be detected whether the level of the liquid 11 is above or below the predetermined value.
