Title: Drive control device of electric motor
Inventor: YOSHIOKA SHOGO
IPC: H02P27/02
Filed: 1994-08-02
Abstract: PURPOSE:To prevent the reduction in the number of rotations and to prevent mis-triggering by outputting a number of trigger pulses using a mis-triggering prevention phase angle control circuit when a continuity angle is large. CONSTITUTION:A comparator 4 arbitrarily sets a target trigger point. A time constant setting circuit 6 turns a trigger into pulses. An oscillation circuit 8 performs re-triggering after nearly the same amount of time passes after the trigger pulses are outputted. Also, a mis-triggering prevention phase angle control circuit 12 outputs a number of trigger pulses when the continuity angle is large and reduces the output of the trigger pulses when the continuity angle is small. Therefore, a number of trigger pulses are outputted in the case of the maximum continuity and at the same time the output of the trigger pulses is reduced in the case of the minimum continuity, thus positively preventing the mis-triggering generated when the phase angle is large.

Title: Switching regulator
Inventor: OE ISAO
IPC: H02M3/28
Filed: 1986-08-27
Abstract: PURPOSE:To simplify circuit constitution and to increase power source efficiency, by a method wherein a dummy load circuit is installed between a rectifier circuit and an output terminal. CONSTITUTION:The output from a DC power source 2 is regulated by a switching regulator comprising a transistor Q1, a transformer 1 and rectifiers 4 and 5, and then supplied to a load. The voltage comparator 11 compares detected output voltage with a set voltage, and controls duty ratio of the transistor Q1 through an oscillator 13 thereby controls the output voltage. Dummy load circuits 30 and 40 are connected between the rectifiers 4 and 5 and the output terminals. The power source voltage is smoothed by a diode 31 and a capacitor 32, and divided for application to the base of a transistor Q3. When the load is not connected, the power source voltage becomes high and the transistor Q3 is rendered on and current flows therethrough, so that duty of the transistor Q1 is not dropped excessively. Further, since a voltage detecting resistor is unnecessary, the circuit is simplified and the power source efficiency is good.

Title: Image fiber and its production
Inventor: SHAMOTO NAOKI
IPC: G02B6/04
Filed: 1993-07-22
Abstract: PURPOSE:To provide a process for production of the image fiber which has good image quality and a round outside shape. CONSTITUTION:A jacket tube 2 having a two-layered structure consisting of a quartz glass inside layer 21 which is relatively lowered in a melting temp. by incorporating a dopant thereon and a quartz glass outside layer 22 which does not contain the dopant and has the relatively high melting temp. is prepd. as the jacket tube 2 constituting an image fiber preform. The many image fibers incorporated with the dopants in at least cores 10 are packed into this jacket tube 2 to form the image fiber preform. This preform is fusing drawn from its one end, by which the image fiber is produced. Since the inside layer of the jacket tube having the low melting temp. acts to suppress the deformation of the cores at the time of fusion drawing, the inside layer lessens the generation of the foam and eventually provents the degradation in the image quality. The outside layer of the jacket having the high melting temp. acts to suppress flattening of the outside shape of the image fiber at the time of fusion drawing and, therefore, the round image fiber is obtd.
