Title: Cathode assembly for magnetron
Inventor: ISHIDA YOSHIO
IPC: H01J23/14
Filed: 1984-01-27
Abstract: PURPOSE:To reduce the oscillating amplitude of a center support and prevent defective filament disconnection by inserting an insulating spacer in one support and forcedly engaging a fixed spring with the other support. CONSTITUTION:The hole 11a of an insulating spacer 11 is inserted in a side support 5 and a recess 11b is formed at the side of the center support 4 side of the insulating spacer 11. A fixed spring 12 made of metal is elastically forcedly engaged with this recess 11b and the center support 4, respectively. Consequently, the movable range of the center support 4 falls on only the gap between the said hole 11a and the side support 5. In addition, since the insulating spacer 11 can be inserted in the side support 5 only, the gap between the hole 11a and the side suport 5 can be reduced considerably. As a result, the oscillating amplitude of the center support 4 is reduced considerably and defective filament disconnection is prevented.

Abstract: PURPOSE: To cut bushes such as small willowy-type stems and larger rigid-type stems by forming a cutting edge with a preceding appendage of a curved part, providing a cutting edge between a lateral outermost point and a point over a saw blade body, with a kerf wider than the saw blade body, and directing a cutting blade outwardly. CONSTITUTION: All of a primary cutting tooth 16, a cutting edge 22 thereof, a point 36 indicating the deep gauge height, and an inclined guide edge 38 are designed for cutting the large rigid-type stems, and a cutting edge 40 comprises a hook-shaped cutting edge structure having a height designed for the small willowy-type stems. A stem 42 is entered into a shallow grooved gap, and is placed on a guide edge 20 for guiding the stem to the hook-shaped cutting edge 40. The hook-shaped cutting edge 40 cuts the stem 42 in a state that it draws the stem 42. A curved slitter/non-raker cutting action of the primary cutting tooth 16 has the important role for smoothly cutting the large rigid-type stems of the bush by a circular saw. An intermediate curved part effectively cuts the kerf width to prevent the stop of the circular saw.

Title: Humidity detecting circuit
Inventor: IDE YUUICHI
IPC: G01N27/04
Filed: 1979-02-06
Abstract: PURPOSE: To prevent the occurrence of chemical action in a humidity detecting element and reduce inspection errors by giving forward and reverse currents in alternating cycles to the humidity detecting element.  
     CONSTITUTION: The output voltage Va of a wave shaping circuit 7 alternates DC power source voltage Vcc and earth potential GND periodically and the middle point voltage Vb of a voltage divider circuit alternates high and low in square waves near the middle value of the voltage Vcc and the earth potential GND. At this time, a current flowing through a humidity detecting element 8 changes its direction alternately. The middle point voltage of the resistors 3, 4 of a bridge circuit changes high and low corresponding to the resistance values shown by the humidity sensing action of the element 8 and the middle point voltage of resistors 5, 6 keeps a prescribed value. Therefore, output Vout is obtained if the positive input of a comparator 9 becomes higher than high negative input.

Title: Taking-up of pitch group carbon fiber
Inventor: FUKAO TAKAHISA
IPC: D01D7/00
Filed: 1986-01-23
Abstract: PURPOSE:To permit the rewinding from a product bobbin free from the thread cut, fluffing, etc. by taking up the pitch group carbon fiber having an elongation modulus of 400ton/mm<2> or more onto a taper end bobbin at an edge angle and a taper end angle of each specific value. CONSTITUTION:When the pitch group carbon fiber 3 having an elongation modulus of 40ton/mm<2> or more and an elongation of 1% or less is taken up onto a bobbin 4, taking-up operation onto a tapered end bobbin is carried out with an edge angle 1 of 0.1-25 deg. and a tapered angle 2 of 10-70 deg.. In concrete, taking-up is carried out in one layer with a prescribed edge angle so that the fibers are not superposed from one edge of the bobbin 4 to the other edge, and then turn-over operation is carried out, and the fiber bundle is taken up in one layer. The edge angle is changed by varying the traverse speed. In other words, generation of thread cut, etc. on rewinding is prevented by sufficiently preventing the state where the fiber bundle taken up onto the upper layer side is dropped into the fiber layer on the lower layer side.

Title: Logical circuit
Inventor: SHIMIZU SHIYOUICHI
IPC: H03K19/0952
Filed: 1982-01-29
Abstract: PURPOSE:To ensure the effective use of a single power supply, by applying the voltage of a constant potential point which is different from the earth voltage or a power supply within a circuit of one side directly to the power supply voltage of the circuit of the other side. CONSTITUTION:The voltage of a common source wiring C of FETQ21-Q23, i.e., the 3rd constant potential point of the 1st circuit A is used to the power supply of the 2nd circuit B. At the circuit B the currents of current source loads FET-Q33 and Q34 flow to an earth regardless of the state of switching FET-Q31 and Q32. As a result, the current flowing to the circuit B from the wiring C is constant. Therefore a current obtained by substracting a fixed current consumed at the circuit B from the current consumed at the circuit A flows to a diode D31, and the level of this current is constant. Thus the potential of the wiring C is always kept at a constant level and therefore can be used to the power supply of the circuit B.

Filed: 1989-01-21
Abstract: PURPOSE:To obtain titanium oxide fine powder excellent in sinterability by dispersing titanium hydroxide in an organic solvent and distilling this soln. at azeotropic temp. or more and separating hydrated titanium oxide from the mother liquor and calcining it. CONSTITUTION:The aimed titanium oxide fine powder is obtained by dispersing titanium hydroxide in an organic solvent and thereafter distilling this soln. at azeotropic temp. or more and separating hydrated titanium oxide obtained therein from the mother liquor and then drying and calcining it. The utilized titanium hydroxide is obtained by such a method that alkali is directly added to a titanium tetrahalide or titanium sulfate soln. or these compds. are allowed to react with water and thereafter alkali is added to the reacted products. Aqueous ammonia is preferably utilized as alkali because the high-purity product is obtained. In this method for producing titanium oxide fine powder, reaction of the soln. is performed in a vessel and toxic gas is unutilized and ungenerated and therefore the fine granular powder can be produced without causing the possibilities of generation of environmental pollution. Further this method is economical because the need for pulverization is eliminated.

Title: Transistor oscillating circuit
Inventor: NISHIMURA TAKESHI
IPC: H03B5/04
Filed: 1983-01-28
Abstract: PURPOSE:To prevent abnormal phenomenon of an oscillated output by using a series circuit comprising a feedback capacitor and a resistive element for a coupling means. CONSTITUTION:The feedback coupling means 41 comprises the series circuit consisting of the feedback capacitor 42 and the resistive element 43, and the resistive element 43 is set to a resistance value stabilizing the oscillated output and is used as a decoupling resistor blocking the subresonance formed by the so- called feedback capacitor and the inductive component of a transistor input impedance. Thus, although the subresonance causes a rapid inversion of temperature drift at its resonance point and the stop of oscillation is caused at the antiresonance point to the subresonance, since the feedback capacitor 42 and the resistive element 43 are used for the feedback coupling means, the transistor oscillating circuit does not produce any abnormal phenomenon because of temperature drift and oscillating characteristic.
