Patent JP-S61281219-A (JP)
Title: Liquid crystal display device
Inventor: NARITA KENICHI
IPC: G02F1/1335
Filed: 1985-05-13
Abstract: PURPOSE:To make the color display showing substantially dark colors possible by interspersing pulverous conductive particles into color filter layers. CONSTITUTION:The color filter layers 5, 5... are interspersed with the many pulverous conductive particles and are provided on the side of a transparent substrate 2 inner further than electrodes 3, 3... via an insulating layer 8 or directly without the intervening layer. Such disposition is provided because of the following reasons: The light transmittance is poor if the hard filter layers 5, 5... are used and therefore the relatively soft color filter layers consisting essentially of an org. high polymer material are used. If the electrodes 3, 3... are provided on such layers 5, 5..., the electrodes 3, 3... are cracked or improperly adhered and are in some cases disconnected or stripped and therefore the lamination of the layers 5, 5... on the electrodes 3, 3... is more preferable.

Title: Voltage and current controller
Inventor: YAMADA KAZUHIRO
IPC: H02M7/162
Filed: 1981-07-01
Abstract: PURPOSE:To eliminate the overshoot which is caused when the control shifts, by providing a control system to change a closed loop control system of the noncontrol state to the unsaturated state based on the output of the closed loop control system of the control state. CONSTITUTION:A control circuit 10 includes an operational amplifier OP4 which amplifies the output signal EC of a voltage control system and an operational amplifier OP5 which delivers the signal V4 which compares the output voltage V2 of the voltage control system with the output voltage V3 of the amplifier OP4 and controls to obtain the same level between the voltage V2 of the amplifier OP2 and the output voltage EC of an operational amplifier OP3. The signal V4 is supplied to the input of the OP2. Accordingly the OP2 is controlled to avoid an unsaturated state based on the signal EC when the OP2 is in an inactive mode. As a result, the time during which the current control is changed to the voltage control is shortened. Thus the overshoot can be virtually eliminated for the voltage of an armature.

Title: Control device for electric motor vehicle
Inventor: KIKUCHI SEIKI
IPC: B60L15/28
Filed: 1981-07-01
Abstract: PURPOSE:To prevent the erroneous operation of a commutation failure protecting circuit by suppressing the generating voltage of a power steering motor at the time of switching forward/reverse switching contactor with a Zener diode. CONSTITUTION:When a forward switch 15 is closed, a coil 17 is excited, and a running motor 3 and a power steering motor 6 are energized through the switches 7, 10 of a forward/reverse switching contactor 2. An oscillator 32 controls the current flow rate of a chopper circuit 5 in response to the depressing stroke of an accelerator. A commutation failure protecting circuit 20 turns OFF a transistor 26 when the chopper circuit 5 is failed in commutation when the motor 3 is operated, thereby allowing a thyristor 21 to be ON, thereby releasing the energization of the coil 17. Since the generated voltage of the motor 6 is suppressed by a Zener diode 24 when the switch 15 is switched, the circuit 20 does not erroneously operate.

Abstract: PROBLEM TO BE SOLVED: To attach and detach an ink tank any time while preventing the mixing of air bubbles into a passage or the leak of ink from the passage at a time of the replacement of the ink tank and avoiding that a user is exposed to danger at the time of the replacement. SOLUTION: A connection part capillary member 18 is provided to the joint part 2 of an ink tank 1 and a filter 22 is provided to the leading end of the ink introducing part 4 on the side of a recording head 3.

At this time, the force pressing the connection part capillary member 18 to the inside of the ink tank 1 is generated but, since a press part 17 is provided to the rear side of the connection part capillary member 18, this pressing force is absorbed by the press part 17 and a contact state is stabilized and the connection part capillary member 18 does not fall into the ink tank 1.

Title: Method and device for finish rolling of steel sheet pile
Inventor: MIURA YOSHINORI
IPC: B21B13/10
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To reduce a roll consumption unit by adjusting at least one out of a roll width and a roll gap of upper/lower rolls of a horizontal roll of an universal mill and adjusting one or more among an inside width, a whole width and a flange thickness of a steel sheet pile under a contacting state at a horizontal roll end face of a vertical roll. SOLUTION: In order to adjust a whole width of a steel sheet pile at finish rolling, roll widths W, W1 of upper rolls 7a, 7b and lower rolls 8a, 8b are changed by actuating a width variable mechanism. As a clearance exists at a center part of roll of the upper rolls 7a, 7b and the lower rolls 8a, 8b, when a difference in level is likely to be generated in a width center of the steel sheet pile, a thickness of a web center part before finish rolling is made smaller than other parts. Adjustment of a flange thickness is done by mutually approaching/separating either the upper rolls 7a, 7b or the lower rolls 8a, 8b, further, for a web thickness, by adjusting a roll gap of the upper/lower rolls.

Title: Active filter
Inventor: HAYASHI HITOSHI
IPC: H03H11/12
Filed: 1995-04-26
Abstract: PURPOSE: To make a filter small and to attain a wide band for the filter by forming the active filter in which a voltage transfer function equal to both a quadratic full frequency pass circuit and a quadratic band blocking circuit is obtained. CONSTITUTION: The active filter 100 is formed by connecting a common gate FET 31, a π circuit comprising a parallel circuit of resistors 24, 25 and a resistor 20 and an inductor 22, and a common source FET 35 in cascade and connecting a common gate FET 39 in parallel with the cascade connection circuit. At least one of the resistors 20, 24, 26 is a variable resistive element and the filter acts like a quadratic full frequency pass filter or a quadratic band blocking filter through the setting of the resistance. A variable inductor is adopted for the inductor 22, then a center angular frequency is changed to obtain the broad band active filter. Since the filter circuit is made up of only TRs, resistive elements and inductors, the size of the active filter is made small.
