Title: Phenolic resin foam
Inventor: OGAWA HIROYASU
IPC: C08J9/00
Filed: 1983-04-25
Abstract: PURPOSE:A lightweight material having high mechanical strength and excellent heat resistance and flame resistance, containing a flame-resistant fiber obtained by oxidation treatment of an acrylonitrile fiber or containing a phenol-formalin resin fiber. CONSTITUTION:A phenolic resin foam containing 1-40wt% flame-resistant fiber of a specific gravity of 1.35-1.8, obtained by oxidation treatment of an acrylonitrile fiber or a phenol-formalin resin fiber. When its specific gravity is outside the range of 1.35-1.8, the above flame-resistant fiber can not impart desired mechanical strength to the phenol resin foam. This is presumably because the flame-resistant fiber having a specific gravity within the above range contains an effective amount of functional groups such as -COOH, -OH, -NH2, and -NH on the surface of the fiber, and a tendency of these functional groups toward reacting with the phenolic resin improves bindability between the fiber and the resin and can impart desired strength to the phenolic resin.

Inventor: WATANABE KAZUO
IPC: H03K19/00
Filed: 1984-04-13
Abstract: PURPOSE:To realize a low power equivalent resistor possible for pre-emphasis and de-emphasis operation by using a switched capacitor filter controlled by a voltage controlled oscillator as a signal transmission circuit. CONSTITUTION:The switched capacitor filter consists of switches S1, S2, capacitors C1, C2 and an inverter 3 as shown in Fig. and becomes the low power equivalent variable resistor with high accuracy and large variable range by changing the oscillating frequency and waveform of the voltage controlled oscillator 2. The switched capacitor filter 52, when it is used for a tape recorder as shown in separate Fig., is switched into two systems at recording and reproduction by using a recording/reproduction switching signal R/P. Since the frequency of control signals phi, phi' and the frequency of an AC bias signal are identical, no audible beat noise is generated at reproduction and emphasis is applied with low power.

Title: Control equipment of ac motor
Inventor: OKURA KAZUMA
IPC: H02P25/026
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To restrain transient vibration by pecisely controlling output torque in speed change. SOLUTION: An integrator 115 integrates a slip angular velocity command value ωse * which a vector control command value operator 101 outputs according to a torque command value T*, and outputs a slip angle phase θse . A rotation position detector 113 outputs rotation angle position θre by a signal from an encoder 103. A power supply angle phase operator 114 adds the slip angle phase θse to the rotation angle position θre , and calculates a power supply angle phase θ. A PWM generator 110 uses the power supply angle phase θ, and outputs a three-phase PWM signal, on the basis of an exciting component voltage command value vγs* and a torque component voltage command value vδs*. An inverter 111 outputs three-phase AC and controls the output torque of an induction motor 100 to be the torque command value T*. Since the rotation angle position which can obtain the newest value by the encode is used for the power supply angle phase calculation, measurement error in speed change is small, and precise control to a command value is enabled.

Abstract: PURPOSE:To decrease the dilution of the material into build-up weld zones and to obtain an overlay metal of a prescribed compsn. having high quality by specifying the inclination of a welding torch and performing build-up welding in such a way that welding arc adjoins the existing build-up weld zone. CONSTITUTION:A welding torch 3 is inclined relatively to the surface of a member 1 to be build-up welded at approximately the same angle as the tangent of the surface of the member 1 at the point where the line extended from the central axis of a welding rod or wire 4 intersects with the surface of the member 1. Build-up welding is then performed in such a way that build-up members 2', 2''... are constituted and that at least a part of the welding arc adjoins the existing build-up weld zone, thereby forming the max. penetration zone by the welding arc existing internally in the adjacent existing build-up zone. The penetration to the member 1 is thus made extremely small except in the first build-up weld zone and the prescribed compsn. of the overlay metal is maintained.

Title: Tilting base for television receiver
Inventor: SUGIYAMA SADAO
IPC: G09F9/00
Filed: 1989-03-24
Abstract: PURPOSE:To attain the stability and to ensure smooth operation when tilt is varied by forming an upper surface of a placing base with a circular-arc with a radius smaller than that of a circular-arc of a lower surface. CONSTITUTION:The upper surface of a placing base 1 is formed with a circular- arc having a radius smaller than the radius of the circulararc of the lower surface. Thus, the thickness 5 of forming is thin in the center of the circular-arc and thicker toward the circumference. Thus, as the tilt of the placing base 1 is increased, a head of a guide chip 3 meshes with the thicker part of the forming. Thus, a fixing force to the placing base is stronger to prevent an extreme front tilt or an extreme rear tilt, and furthermore, the thickness of the forming meshing with the head of the guide chip 3 is thinner in a direction where the placing base 1 is changed from the tilt state into the horizontal state and the smooth operation of varying the tilt is maintained.

Abstract: PURPOSE:To obtain a semiconductor device which is low in ON-state voltage, high in switching speed, and small in switching loss. CONSTITUTION:An N<-> epitaxial layer 1 provided with a P<+> substrate 2 and a projection 3, an N<+> diffusion region 4, and a P<+> diffusion region 13 are formed between electrodes 9 and 10, and control electrodes 6 are formed on an insulating film 5 sandwiching the N<+> diffusion region 4 and the projection 3 between them. With the electrode 10 at a higher potential than the electrode 9, the potential at the control electrodes 6 is varied whereby a potential barrier is generated or conductivity modulation is produced inside the N<-> epitaxial layer 1, so that a semiconductor device is turned ON or OFF. By this setup, holes injected at a turn-OFF time are extracted through the P<+> diffusion region 13, and the P<+> diffusion region 13 is lessened in resistance and distance without changing the N<+> diffusion region 4 in area when the holes are drawn out. Therefore, a semiconductor device can be lessened in switching loss and enhanced in switching speed as kept low in ON-state voltage.
