Title: Annealing method for core of motor
Inventor: WADA MASAMI
IPC: H02K15/12
Filed: 1987-04-30
Abstract: PURPOSE:To reduce the cost of a core and obtain the same characteristic as conventional one, by using induction heating method, and by annealing the only section having high density of magnetic flux on the periphery of the slot of the core, and the large generation quantity of iron loss. CONSTITUTION:When a core is annealed by an induction heating method, then the only section having high density of magnetic flux on the periphery of the slot 1 of the core is annealed by setting the frequency f of current based on a distance from the outer diameter of the section having high density of magnetic flux on the periphery of the slot 1 of the core. By this annealing, iron loss is reduced, and the density of magnetic flux in a low magnetic field is increased, and due to such phenomenon, the magnetic characteristic of the core is improved. Besides, by partial annealing with the induction heating method, energy efficiency due to current control is not lowered, and a time can be shortened, and the annealing can be applied to mass production, and so the core can be economically obtained.

Abstract: PURPOSE:To improve matching with respect to a clock between a scanning mode >=2,000 developed newly and the scanning mode <=2,000, and a reference broadcasting system by providing an A/D conversion part, etc., to quantize an output signal from a TV camera. CONSTITUTION:The TV camera 35 is set at an available scanning mode by the command of a control part 6, and the output signal from the camera 35 is quantized via the A/D conversion part 37. In other words, the output signal 300 from the camera 35 is impressed on an OP-Amp circuit of the conversion part 37, and a switch SW is turned on by a signal 507 when a clock signal 500 is set at 9.6923MHz. Thereby, since an electrostatic capacitance C2 is attached on a C1, a passing frequency band area goes to around 5MHz. Also, when the signal 500 is set at 19.3846MHz, since the signal 507 disappears, the switch SW is turned off, and the passing frequency band area goes to 10MHz, that is a double frequency. In such a way, it is possible to provide the matching and the interchangeability between the scanning mode of 500 and that of 1,000 and 2,000 or more, and also, the matching with respect to the clock of the reference broadcasting system.

Title: Resin-sealed type semiconductor device
Inventor: ANJO ICHIRO
IPC: H01L21/60
Filed: 1989-04-28
Abstract: PURPOSE:To prevent occurrence of a crack in the lower side of a bonding pad part even when a thermal stress of a temperature cycle or the like is applied thereto, by a method wherein, in a first fore-end part wherein a bonding pad and an alloy are formed and connected together electrically, the ratio between the thickness of the first fore-end part and the width of the alloy therein are made to be a prescribed one. CONSTITUTION:To a ball-shaped bonding part 5' of a wire 5 for a connector on a bonding pad part 6 of a pellet 4, a shearing force due to shrinkage of molding resin is applied from the direction of the outside of the pellet toward the center thereof. Since this shearing force presses an Au ball 5', a moment is caused, a tensile stress is generated in the end part of the Au ball, and a crack occurs when the tensile stress exceeds a breaking strength of the pellet. When the thickness of the Au ball is made small by a mechanism, a pressed area (sectional area) of the Au ball decreases and therefore the stress diminishes, thus causing no crack. When an area of junction formed by an Au-Al alloy 10 is widened, likewise, a concentrated stress applied to the end of the Au ball diminishes and therefore the occurrence of a crack 14 can be prevented. In the relationship between the thickness (d) of the Au ball and the width l of the Au-Al alloy on a pad in the area of junction, in particular, the occurrence of the crack can be prevented most effectively when the d/l ratio is 0.2 or below.

Title: Swivel stop mechanism for dynamic damper
Inventor: KAMIYA TAMOTSU
IPC: F16F15/30
Filed: 1979-08-25
Abstract: PURPOSE:To stop the swivel motion of a damper when it is rotated at high speed and prevent a damage to the bearing in its pivotally mounted part, by providing a pair of stopper pins radially movable in accordance with the rotational speed of a flywheel further forming the side of the damper into a fan shape. CONSTITUTION:In a dynamic damper of such a constitution that a speed variation of rotation in a drive power source is reduced, a pair of stopper pins 9 radially movable in accordance with the rotational speed of a flywheel 1 are provided, further the side of a damper 7 is formed into a fan shape. As the rotary drive power source increases its rotation at high speed, a weight 13 is caused to move outward with the pins 9 to form narrower clearances between fan-shaped sides 7a of the damper 7 and the pins 9. While as the rotation increases to high speed a variation of torque decreases to cause the damper to swivel in a less degree of angle. When the speed of rotation exceeds a prescribed speed, the weight 13 and the pins 9 reach an outermost position, the pins 9 hold the damper 7 from its both sides to stop its swivel motion.

Title: State machine control circuit
Inventor: OMURA HISAHIDE
IPC: G06F11/00
Filed: 1989-04-27
Abstract: PURPOSE:To prevent the generation of a system deadlock even if any kind of state is generated in the course of a control operation by setting an abnormal state where a state number is allocated newly, and always transiting the state to this abnormal state when abnormality is generated in the course of control operation. CONSTITUTION:When a state number S1 (number except 0 - 4, 7) is inputted, a logic circuit 23 sets the next state number S2 to 0 (=000; abnormal state state 0). When an access signal is abnormal, an abnormality detecting timer 21 is started, and when a data strobe DS is not detected within the prescribed time, the timer 21 outputs a time-out signal TO. In the case of an access signal idle state 7, since a signal TO does not become an input condition, the state is maintained as it is. On the other hand, when the timer 21 becomes time-out, and also, the signal of the access end is not applied from a processor, a hard error signal is sent out to a state number latching circuit 25. Consequently, the circuit 25 outputs S1 000 and the state number of a state machine control circuit become 0,kand the circuit becomes and abnormal state.
