Title: Bipolar type random access memory
Inventor: UCHIYAMA TAKEO
IPC: H01L27/10
Filed: 1983-08-22
Abstract: PURPOSE:To expand the operation margine of a bipolar type RAM by switching a reading reference voltage in accordance with the number of memory cells to be read out. CONSTITUTION:When an operation mode control signal FS is in the low level and only one memory cell constituted by transistors (TRs) Q4, Q5 forming an FF by the cross coupling of word lines WO is to be read out, differential TRs Q1, Q2 in a current switching circuit are turned on and off respectively. consequently, constant current I1 does not flow into a resistor R1 and the readout reference voltage is determined by constant current IO flowing into the resistors R1, R2. When the signal FS is turned to the high level to read out many memory cells simultaneously, the constant current I1 also flows into the resitor R1 and the reading reference voltage is dropped. The same rule is applied also to other word lines and the simultaneous reading of plural blocks reduces the reference voltage as compared to the memory reading of one block, so that the level margine of the holding voltage of the memory cells is prevented from deterioration and the operation margine of the bipolar type RAM can be expanded.

Title: Centrifugal clarifier
Inventor: ISHIHATA AKIRA
IPC: B04B1/02
Filed: 1980-10-29
Abstract: PURPOSE:To detect the quantity of sludge accumulated at the inside of a rotating body by installing a displacement gauge detecting the displacement of the axial direction of a rotary shaft in an apparatus to support the rotary shaft with magnetic radial bearings and magnetic thrust bearings. CONSTITUTION:A detecting terminal 10 of a displacement gauge which detects the interval between the lower face of a disk 8 and the detecting terminal without contacting is provided to an upper cylindrical member 5b. The interval between the lower face of the disk and the detecting terminal at the start of operation is regarded as 0 in the quantity of accumulation of the sludge. With the operation time passing, sludge is accumulated at the inside of the rotating body 2 and the weight of the body 2 is increased. Therefore, the shaft 4 descends against the resisting force of thrust bearings and the interval between the disk 8 and the detecting terminal 10 is reduced. The reduction of the inteval corresponds to the quantity of accumulation of sludge. After finding the relation between the change of interval and the quantity of accumulation from experiments, the scale of the displacement gauge is calibrated.

Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To realize an appropriate large capacity concerning a recording medium by setting a data recording density in a header region and that in a recording and reproducing region at different values from each other. SOLUTION: A header is a reproduction-dedicated region. In an MO area used as a region accepting magneto-optical recording/reproduction, user data or the like are recorded. As a data modulation method, a (1-7) run length limited code modulation method ('(1-7)RLL') is employed. The frequency of a reproduction clock DCK in the MO area is set, for example, at 2fc, where fc is a clock frequency in the case of an MO disk. On the other hand, in the header, a (2-7) run length limited code modulation method ('(2-7)RLL') is employed as the modulation method that is different from that employed in the MO area. In addition, a frequency of the reproduction clock DCK is set either at 2fc, which is the same as that in the MO area, or at αfc (where 1<α<=2) which is different from that in the MO area.

Title: Thick film resistor for heater
Inventor: IWANAGA SHIYOUICHI
IPC: H01C7/00
Filed: 1977-12-21
Abstract: PURPOSE: To make a heating resistor of good heat-resisting property and high- voltage-resisting property and low electric resistance variation, by using at least one of BaRuO 3 , CaRuO 3  and SrRuO 3  and a binder glass of high softening temperature.  
     CONSTITUTION: The BaRuO 3 , CaRuO 3  and SrRuO 3  are synthesized by high-temperature reaction and have a high stability at high temperature. At least one of them is used as electroconductive constituent. Amorphous glass of about 700 to 850 °C in softening temperature is pulverized, thereby producing glass frit of 3 μ or less in grain size. The glass frit and the powder of the electroconductive constituent are mixed with each other. The mixture is kneaded with a vehicle, thereby making  paste. The plaste is printed between gold terminals printed and baked on an alumina substrate and is then baked, thereby making the thick film resistor for heater. If  the softening temperature is lower than 700°C, the heat-resisting property is low. If  the softening temperature is higher than 850°C, baking above 1000°C is needed and  therefore the production cost is high.

Title: Ventilator for heat exchanger
Inventor: UTAGAWA TOSHIO
IPC: F24F7/08
Filed: 1986-06-30
Abstract: PURPOSE:To make it easy to clean a heat exchanger when its airflow frame is stained with oil soot and make it possible to prevent the increase in resistance to the air flow by adopting a ceramic material for a heat exchanger and making the heat exchanger freely removable from its ventilator. CONSTITUTION:A heat exchanger 2 is installed which gives to the supply air B the heat recovered from the air A which is exhausted into the inside of the main body 1 of a ventilator of the heat exchanger. The material of the heat exchanger 2 is ceramic and a heat exchanger 2 is freely removable from the main body 1 of the ventilator of the heat exchanger. As a result, it is possible to recover heat from the exhaust air that contains much of an oily substance and prevent reduced heat exchanging efficiency by removing easily the soot attached to the heat exchanger by heat-treating the soot and prevent a reduced amount of ventilated blast. Further, because the ceramic material is used, the heat exchanger excels in corrosion resistance even if it is installed in a high temperature and high humidity atmosphere.

IPC: H02K23/54
Filed: 1977-12-19
Abstract: PURPOSE: To accelerate the heat transfer from an armature coil, by embedding a layer-built iron core in one side of a rotary disc and coupling the plate-like armature coil to the iron core through an insulator plate.  
     CONSTITUTION: An armature 1 has the iron core 3 cast in one side of a center piece 2, which serves as the rotary disc. A copper plate is punched to winding segments by a press. A number of such winding segments are bonded to the iron core 3 through such as mica. The armature coil 4 is bonded to the winding segments through the insulator plate 5. A stator 6 has a flat annular permanent magnet 8 bonded to one side of an end frame 7, which serves also as a magnetic circuit part. The armature 1 and the stator 6 are rotatably coupled to each other through a bearing shaft 10 and a bearing 10a. Since the heat of the armature coil 4 is transferred through the iron core 3, the heat transfer is accelerated. Because the iron core 3 is integrated with the armature coil 4, the thickness of the coil and the gap of the magnetic circuit can be reduced. Therefore, the output can be increased.

Abstract: PURPOSE:To reduce a decrease in an output by applying the longitudinal center of a screen electrode to an ion generator with adhering means having rigidity, and allowing at least both ends of the electrode to adhere to the generator with adhering means having elasticity. CONSTITUTION:When a head is heated by a heater 11 at the time of use of the head, a screen electrode 22 and a second insulating layer 18 are relatively displaced at the part of an adhesive 34 having elasticity due to the difference of thermal expansions of a first insulating layer 15 and the electrode 22, the opening 23 of the electrode 22, the hole 16a of an ion generator 10 and an air region 16b are deviated. However, since the adhering part of the adhesive 32 having rigidity is rigid, a strain deformation does not occur, their positional deviation becomes zero, and can be set to the value of 1/2 of the deviation of the electrode 22 and the layer 15 due to their normal thermal expansion difference. Accordingly, it can prevent a decrease in the output from decreasing, the density of a recorded image from decreasing and an irregularity, blur from occurring.
