Title: Electromagnetic flowmeter
Inventor: GOTO SHIGERU
IPC: G01F1/60
Filed: 1986-07-04
Abstract: PURPOSE:To remove an error due to the delay of a magnetic field by adjusting a gain adjusting means through a proportional arithmetic means so that a 1st and a 2nd signal voltages which are processed by a 1st and a 2nd signal processing means become equal to each other. CONSTITUTION:The output voltage of a preamplifier 17 is amplified 21 and made into a DC voltage based upon a low-frequency voltage from a low frequency voltage source 36 as a reference voltage by a demodulator 22, and the voltage is outputted to an adder 25 as a signal voltage VL1 through a low- pass filter 24. Further, the output voltage of the amplifier 17 is amplified 30 and made into a DC voltage based upon a high-frequency voltage from a high- frequency voltage source 38 as a reference voltage by a demodulator 31, and the voltage is outputted as a signal voltage VH1 to an addition point 25 through a variable gain amplifier 39 VH1 to an addition point 25 through a variable gain amplifier 39 and a high-pass filter 34. Then, the proportional arithmetic circuit 40 inputs the voltage VL1 as well as the voltage obtained by passing the output of the amplifier 39 through a low-pass filter 41 and computes their ratio. The gain of the amplifier 39 is controlled with its output so that the signal voltages VL1 and VH1 become equal to each other.

Abstract: PURPOSE:To enable the realization of an electrically programmable IC with 1- chip by a method wherein each point of intersection of the group of signal input wirings with the group of signal output wirings is provided with a switching element, and the ON-OFF state of each switching element is controlled. CONSTITUTION:An IC chip is composed of a functional block region, a switch matrix region, an X-Y decoder, a power source line region, etc. In the switch matrix region, switches capable of having ON-state or OFF-state are arranged at the points of intersections of the group of inpu lines 34 and the group of output lines 35, so that the input lines and the output lines intersecting with each other are electrically connected when these swtiches are ON, and that they are electrically insulated when the switches are OFF. The input-output of signals of two circuit blocks is carried out only via this wiring matrix. Selection of the switch of signals to be turned ON in such a manner enables the electric connection of an arbitrary output line to an arbitrary input line, resulting in the control of the ON-OFF state; thereby a desired IC is constructed.

Title: Electronic camera
Inventor: KUBO BUNJI
IPC: G11B21/12
Filed: 1989-06-20
Abstract: PURPOSE:To prevent a magnetic sheet from receiving an adverse effect by immediately actuating a head retreat means when it is detected by a detection means that the locking of a battery lid is released. CONSTITUTION:When it is detected by the detection means 58 that the lock means 59 and 60 of the battery lid 7 are released, the head retreat means 40-42 are immediately actuated. Therefore, even when a jacket is left in a magnetic recording and reproducing device 55 for a long time, the abutting track of a magnetic head 112 is not left on the magnetic sheet 101 in the jacket. Since the lock means 59 and 60 of the battery lid 7 are released whenever a battery 50 is exchanged before the prescribed time for retreating the head elapses, the detection means 58 detects it and the head retreat means 40-42 are actuated. Then, the head 112 is retreated. Therefore, the abutting track is not left on the magnetic sheet 101. Thus, the magnetic sheet is prevented from receiving the adverse effect.

Title: Electrostatic recording type plotter
Inventor: FUJISAWA TATSUYA
IPC: G03G15/05
Filed: 1987-06-24
Abstract: PURPOSE:To obtain a plotted drawing having high quality by providing a mechanism for preventing the electric discharge of an electrostatic charge image to the developing part of an electrostatic recording type plotter. CONSTITUTION:Electric charge is charged on electrostatic recording paper 1 by a head 2 according to the information on a plot pattern at the time when said paper passes above a recording head 2. The recording paper is then immersed in a toner developing soln. 5 in a tank 4 sprayed from a pipe 6a for circulation at the time of passing the developing part 3 and is thereby developed, by which the toner is stuck to the charged electrostatic charge image of the recording paper 1. The developing part 3 descends automatically and parts from the recording paper 1 by actuation of a mechanism 7 when the state of waiting the information from a computer is attained and the outputting of the plotted drawing stops. Since the contact of the metallic parts with the charge region is thereby prevented, the discharge is prevented. The sticking property of the toner is, therefore not fluctuated regardless of whether the output is transiently stopped or not. The plotted drawing having no unequal concns. and recording defects is thus obtd.

Title: Variable attenuator
Inventor: JIRUBEERU PUTEIJIYAN
IPC: H03H7/25
Filed: 1988-06-28
Abstract: PURPOSE: To handle a large power output by providing a limiting element which has its parallel attenuation branch connected to a variable resistance element in series and matching the internal impedance of a transmitter circuit with its value. CONSTITUTION: When no control voltage is developed at a control terminal 20, a voltage generator supplies a voltage so that diodes 10 and 12 turn on and diodes 11 and 13 turn off, and attenuation, therefore, becomes maximum; and the transmitter circuit 2 is branched by a resistance 25 and its value corresponds to the internal resistance. When the voltage at the terminal 20 rises, the diodes 11 and 13 begin to conduct and the conduction currents of the diodes 10 and 12 decrease. When the diodes 11 and 13 enter their maximum conduction states, the diodes 10 and 12 completely turn off and the the attenuation becomes minimum. Consequently, S.W.R (standing wave ratio) is held below 1.6 with respect to attenuation which varies from <=2dB to >=50dB.
