Title: Burner device
Inventor: MIKURA TETSUYA
IPC: F23N1/00
Filed: 1981-03-30
Abstract: PURPOSE:To provide proper gaseous fuel ejection velocity corresponding to the required heat output by a mechanism in which the nozzle opening area is designed to increase with increase in the gas fuel flow rate and decrease with decrease in said flow rate. CONSTITUTION:The vertically moving plate 4, when the flow rate of gaseous  fuel is low and when the burner device 5 has low internal pressure, rises to  cause the conical shutter 2 to further close the nozzle 1, making its opening a rea narrower. On the other hand, with increase in said flow rate and with increase in the pressure of gaseous fuel within said burning device, the fluid in  the cylinders 7 and 8 is compressed or the piston 3 is pushed down to cause  said vertically moving plate 4 which is supported by the fluid to drop. With  this, said conical shutter 2 descends to make wider the opening area of said nozzle. In this way, proper gaseous fuel ejection velocity corresponding to the required heat output is made available.

Title: Vertical magnetic recording medium
Inventor: TSUTSUMI KAZUHIKO
IPC: H01F10/14
Filed: 1984-03-13
Abstract: PURPOSE:To obtain a vertical magnetic recording medium suitable for vertical magnetic recording by forming said medium which consists of an alloy contg. Fe, Nd and >=1 kinds of elements among Ti, Zr and Hf and in which the axis of easy magnetization exists in the direction perpendicular to the film plane. CONSTITUTION:If the content of Fe is <=5atom%, the satd. magnetization decreases too much and if said content exceeds 85atom%, the axis of easy magnetization exists no longer in the vertical direction and therefore Fe is incorporated preferably at 50-85atom% in the alloy. If the content of Nd is <=5atom%, the axis of easy vertical magnetization exists hardly in the medium and therefore Nd is preferably incorporated at 5-50atom% therein. The axis of easy vertical magnetization is made to exist hardly with Fe and Nd alone and therefore >=1 kinds among Ti, Zr and Hf are incorporated into the alloy, by which the satd. magnetization is decreased and consequently said elements are incorporated at <=35atom%.

Title: Optical negative feedback circuit
Inventor: FUKUGAHARA TSUTOMU
IPC: H01L33/00
Filed: 1986-03-05
Abstract: PURPOSE:To prevent the deterioration in an SN ratio accompanied by negative feedback and to improve the distortion characteristics in a light emitting element, in an optical negative feedback circuit in a photoelectric conversion device, by providing a distortion compensating means on the input side of a driving transistor. CONSTITUTION:An input signal (a) drives a driving transistor 2 through an amplifier 3. A light emitting element 1 emits light in correspondence with a driving current, and a light output (b) is generated. Part of the light output is inputted to a light receiving element 5. The received signal passes through an amplifier 6 and a bandpass filter 7. The component at the outside of the band of the main signal is taken out. A level detector 8 generates a DC output. A signal, which is obtained by dividing the voltage of the input signal, is always given to an FET 10 as a gate voltage through a resistance voltage divider 11. Therefore constant distortion is imparted to the input signal. The output of a comparator 9 is superimposed on the signal from the resistance voltage divider 11 and the result is added to the FET 10 as the gate voltage. Then the amount of the distortion generation in the input signal is increased. Thus the generation of the distortion in the light emitting element 1 is decreased by compensation.

CONSTITUTION:A paper guide member 13 with a projecting part on its upper part is provided on the transfer paper carrying path between a toner transfer means including a corona discharge wire 4 for transfer and a toner fixing device including fixing rollers 20 and 21. The trailing edge of the transfer paper 26 passes through a photosensitive body 1 and the toner transfer means and the transfer paper 26 is held by the toner fixing means 20 and 21 and is carried in the paper ejecting direction. At this time, the angle theta is made by the tangent line 102 of the toner transfer position and the extension line 105 of advancing angle of the transfer paper 26 held by the fixing rollers 20 and 21. The angle thetais downward set 180 deg. or below. Consequently, even when width between the upper projecting part of the paper guide member 13 and the fixing means is 160mm or below, that is, the device is miniaturized, the transfer paper 26 still maintains sufficient elasticity. Thereby, imperfect transfer is prevented.

In an  ultrasonic wave generator 3, electrodes 3a for producing ultrasonic wave, formed in  the shape of a comb, are located at the left of the object 2, and an oscillator 3b is connected to the electrode 3a. Further, sound absorbing agents 3c are formed at the ends  of the object 2, and the frequency of ultrasonic waves varies with a change in the pressure P. A fiber 4 for projection irradiates with light 1 at an angle thetai to the vertical  axis of the object 2. In a fiber 5 for collection, a reference light L2, whose reflecting  angle is unchangeable against a change in the frequency of the ultrasonic waves, and a  diffracted light L3, whose diffraction angle varies, are obtained. A change in a diffraction angle thetad is measured from the reference light L2 and the diffracted light L3 to measure the pressure P. This permits measuring of only the pressure P through correction of vibration and temperature change.

As the heat shrinkable fibers, polyester type ones are especially proper from the aspect of strength, chemical strength, releasability or extensibility. By this constitution, large resistance is not generated by water passing resistance of about -10--16KPa and filtering can continuously be performed and the amt. of transmitted water is made much under low pressure and energy can be conserved. The filter can simply be washed and repeatedly utilized.
