Patent JP-S6330013-A (JP)
Title: Amplifier circuit
Inventor: UTSUNOMIYA MASAAKI
IPC: H03F1/22
Filed: 1986-07-24
Abstract: PURPOSE:To prevent the reduction in the S/N due to the attenuation of a signal voltage by cancelling the base current of the 1st or the 2nd transistor (TR) forming a differential pair by the base current of the 4th or 3rd TR so as to keep the input impedance high. CONSTITUTION:Since the resistance R12 is sufficiently smaller than a resistance R13, the signal inputted to an input terminal iN1 is fed to bases of the 1st and 4th TRs Q12, Q21 in phase. A collector current of the 2nd TR Q22 in cascade connection to the 4th TR Q21 in opposite phase to the collector current of the TR Q12 is multiplied by 1/hfe (hfe is a current amplification factor) by the TR Q21 and fed back to the emitter of the TR Q12. Thus, the base current of the TR Q12 is cancelled and the input impedance of the amplifier circuit viewed from the input terminal IN1 is increased. Since the resistance R22 is sufficiently smaller than the resistances R21, R23, the input impedance of the amplifier viewed from the input terminal IN2 is increased. Since the input impedance of the amplifier is increased, the reduction in the S/N due to the attenuation of the signal voltage is prevented.

Title: Biological disposal of contaminated water
Inventor: NAKANISHI HARUJI
IPC: C02F3/08
Filed: 1979-12-27
Abstract: PURPOSE: To improve a disposal efficiency and to make an operation simple, by arranging plate members for adhering bacteria films in a cylindrical vessel positioned rotatably and horizontally, and carrying contaminated water through the vessel.  
     CONSTITUTION: A cylindrical vessel 1 positioned horizontally is provided with a contaminated water charging inlet 2 at its one end, and with a clarified water discharging outlet 3 at its other end. In the vessel 1, a plurality of plate members 5 are arranged and fixed for adhering bacteria films thereon. A predetermined amount of contaminated water is continuously introduced into the vessel 1 being rotated. Organics contained in the water are decomposed by aerobic bacteria adhered onto  the plate members 5, and decontaminated water is discharged through the outlet 3.  Due to the rotation of the vessel itself, bacteria grow well not only on the plate  members but also onto the inside surface of the vessel, so that a bacteria-adhering  surface area is enlarged. Consequently, contaminated water is disposed with a high  efficiency. Besides, it is not necessary to use a protect cover which has been required so far for a decontamination water vessel.

Title: Method for writing in nonvolatile semiconductor memory
Inventor: NAKAYAMA TAKESHI
IPC: G11C16/06
Filed: 1988-07-12
Abstract: PURPOSE:To make page-mode writing possible by applying a specific voltage across required transistors in accordance with the erasure and program modes. CONSTITUTION:When a selected word line 3 corresponding to a page to which the page mode is to be performed is set to a high voltage and 0V is supplied to a non-selected word line 4 and all bit lines 1 and 2 while source lines 5 and 6 are floated, a high voltage is applied across the control gates and drains of memory transistors (TR) Q1 and Q3, the control gates of which are connected with the word line 3, and a high electric field is generated between a floating gate and drain. As a result, electrons are injected from the drain toward the floating gate due to a tunnel effect and the threshold voltages of the TRs Q1 and Q3 rise. Accordingly, logic '1' is written and the selected TRs Q1 and Q3 are erased. Therefore, when a specific voltage which is opposite to the voltage applied at the time of erasure is applied across the control gates and drain areas of the TRs Q1 and Q3 and a low write inhibit voltage is applied across the gates and drain areas of other non-selected TRs Q2 and Q4, page- mode writing can be performed.

Filed: 1991-05-27
Abstract: PURPOSE: To simply and surely conduct the coil manipulation to a stator by automatically coupling an intermediate lead wire to a terminal member arranged on a stator terminal board from a plurality of coil sections wound on a stator pole. CONSTITUTION: When the predetermined number of turns of a coil wire 50 is wound on a stator pole 32 by a coil takeup shuttle, twisted area of wire is surely held between the coil 50 and takeup shuttle and wire position is determined within the range of a slot 41 located on a terminal member 40 on an stator terminal board 31 to hold the twisted area together with a terminal member 40. Therefore, when the takeup shuttle has started again the operation, twisted area of the wire is held by the external part of the terminal member 40 and is then surely wrapped. Therefore, on the occasion of coupling the intermediate lead wire to the terminal member, it is no longer required to cut the intermediate lead wire.

Title: Driving method for magnetic bubble memory device
Inventor: MAJIMA NIWAJI
IPC: G11C11/14
Filed: 1985-08-09
Abstract: PURPOSE:To eliminate errors produced in a start/stop mode for the transfer of bubbles and to secure the nonvolatile properties of a bubble memory, by stopping the transfer of bubbles after a rotary drive magnetic field is revolted up to the phase slightly ahead of the phase of a holding magnetic field. CONSTITUTION:When the bubble is transferred by a bit, the drive magnetic fields HX and HY in the X and Y directions are used and therefore the magnetic field HX has an overshoot when the transfer of bubbles is stopped. A rotary drive magnetic field HR is obtained by synthesizing both magnetic fields HX and HY. The magnetic field HR draws such a resurge where the leading starts at an original point 0 deg. with a phase 0 deg. of a holding magnetic field HO and further the point 0 deg. is reset when the field HR is turned up to a phase ahead of the phase 0 deg. by theta after the field HR turned by 360 deg. from the phase 0 deg. and returned to the phase 0 deg.. In other words, the magnetic field HR is stopped at a phase where the field HR turned further by theta than the phase of the field HO when the transfer of bubbles is stopped. This angle theta is equal to an overshoot angle that should be less then 45 deg. and set preferably at about 30 deg..
