IPC: H04N3/16
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a horizontal deflection output circuit by which the power loss of the entire circuit is reduced, even when a horizontal deflection frequency is high and the reduction effect of the power loss is enhanced stably even if environment such as the horizontal deflection frequency and ambient temperature or the like is changed.

Title: Manufacture of rotary armature core having skew
Inventor: AIISO TAKASHI
IPC: H02K15/02
Filed: 1988-08-30
Abstract: PURPOSE:To manufacture a long laminated core by forming separated projections on a fixed number of laminates having V-projections each prescribed sheets, dividing these laminates into upper and lower laminates and then returning and rotating a punch and a die. CONSTITUTION:The laminates 35 having separated projections 34 each are formed of suitable number of laminates and laminated on laminated cores but upper and lower laminated cores 33, 36 are divided because separated projections 34 are formed, as a result, increase of weight by lamination is avoided. After the laminates are laminated, the punch and the blanking die return and rotate, therefore, the V-projection of the laminate which is laminated later agrees to the V-projection of the laminate having the separated projection and lamination is prevented from slipping.

Title: Active resistor device
Inventor: KAWAMURA NOBUHISA
IPC: H03H11/46
Filed: 1988-08-30
Abstract: PURPOSE:To set a resistance with high accuracy by using both terminals of a series circuit comprising a current control element and a resistor as a resistance value output terminal. CONSTITUTION:A voltage E at a terminal 1 is fed directly to a noninverting input terminal and a voltage drop I.R0 by a current I flowing through a reference resistor 6 is applied to a multiplier 4 to an inverting input terminal. Thus, an input terminal voltage applied to the inverting input terminal of an amplifier 5 is expressed as I.R0.X, where X is a setting multiple of the multiplier 4. With the feedback quantity of the amplifier 5 selected sufficiently, since almost no current flows to a gate of a FET 3, the relation of E=I.R0.X exists in the input voltage of the amplifier 6. The relation of R=R0.X is obtained by substituting the relation of E=I.R0.X to equation I to obtain an equivalent resistance R. Thus, the equivalent resistance R varies proportional to the setting multiple X of the multiplier 4 and the resistance is set with high accuracy.

Abstract: PURPOSE:To obtain a tracking control signal having a wide range of linearity of the displacement difference signal by selecting the output signal obtained by changing the peak value of the sum signal to zero or the output signal obtained by inverting the sum signal according to the positive or negative difference signal. CONSTITUTION:A tracking signal detecting circuit of a magnetic recording and reproducing device obtains a signal (d) by shifting the level of the sum signal (b) of the output of a sum operational amplifier 14 by an amount equal to voltage EV through a difference signal amplifier 16 and divides the signal (b) into the one that is supplied directly to the 1st switch SW1 of an analog switch 19 and the other that is supplied to the 2nd switch SW2 of the switch 19 through an inverting circuit 18. While the difference signal (a) of the output of a difference operational amplifier 13 is supplied to a sum operational amplifier 20 and a comparator 15. Thus the positive/negative signal C in obtained through comparison carried out with voltage zero and used as two switching signals for the switch 19. Then the switch 19 is selected by the signal C and a sum signal (e) underwent a level shift is obtained. Then the signal (a) is transmitted through the amplifier 20 to obtain a difference output (f) having the improved linearity.

Title: Microwave oven
Inventor: HAYAMIZU KATSUAKI
IPC: H05B6/72
Filed: 1993-08-31
Abstract: PURPOSE:To prevent uneveness in heating, and enable favorable high frequency heating to be applied. CONSTITUTION:In this microwave oven, a radiative antenna 43 radiating microwaves is rotatably provided for the tip end of the fixed antenna 42 of a magnetron 41 while being eccentric.

Title: Flexible,foamable fireproofing coating composition
Inventor: RICHIYAADO EMU NUJIENTO
IPC: B05D7/24
Filed: 1995-08-24
Abstract: Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of     (i) zinc,   (ii) boron,   (iii) phosphorus, and (iv) an expansion gas upon thermal decomposition. The composition is capable of forming a carbonaceous char upon exposure to heat or flame, with the proviso that the cured, unburned composition has sufficient flexibility that it passes at least 10 continuous cycles of a cold cycle test without cracking. The cold cycle test involves the following steps: the composition is applied at a thickness of 0.5 inch (12.7 millimeters) to a 10 inch (0.254 meter) section of a 4W13 I-beam having two thermocouples attached to the surface, allowed to cure at ambient temperature for 16 hours, force cured for 5 days at about 60 DEG C and subjected to the cold cycle test. For one cycle, the beam is placed in a freezer operating at a temperature between about 0 DEG F (-18 DEG C) and about -10 DEG F (-23 DEG C) for sufficient time for the steel to reach a temperature between about 0 DEG F (-18 DEG C) and about (-10 DEG F) -23 DEG C as determined by the two thermocouples attached to the surface of the beam beneath the coating, removed from the freezer and a 50 square inch area (0.0323 square meter) of the surface warmed as shown in FIGS 1 and 2 by passing a heat gun (Model No. HG 50146, Alpha Division of Loral Corp, 14 amp: minimum temperature at tip 500 DEG F (260 DEG C)) a distance of 0.5 inch (12.7 millimeter) from the surface, uniformly over the surface until the surface temperature reaches 110 DEG F (43 DEG C) within a 3 minute period, as determined by a thermocouple moved about the surface and allowed to stand for at least 2 hours at ambient temperature.   <IMAGE>

Title: Cup molding machine
Inventor: OGIWARA AKIRA
IPC: B31B50/00
Filed: 1990-08-16
Abstract: PURPOSE:To mold efficiently a beater line on an end part at the small-diameter side of a cup in a tapered form, by a method wherein a driving part of a female mold is worked, the diameter of the electric heating wire molding member is expanded by following working of a diameter-expanding member of a male mold and its protrusion presses a cut main body part. CONSTITUTION:A recessed part of a mortar of a female mold is fitted over the top part of a cup 32 under a state where the cup 32 is inserted into a male mold. When a main spindle driven downward, a wedge driving shaft supported by the spindle presses a wedge 9 downward by opposing upward energizing force of a spring. A chuck 11 begins diameter-expanding by a tapered part 9b of the wedge 9 and when a downward movement of the wedge 9 progresses further a protrusion 13a of a chuck forming member 13 is ejected outward through a gap between a male mold main body part 6 and head member 12. With this construction, a beater line 32a can be formed on an outer circumferential part of the cut 32. Since the chuck 11 is formed within the male mold like this, the beater line 32 can be molded in the vicinity of an end part of a small-diameter side of a cup in a tapered state reliably in a short time.
