Title: Helix type waveguide
Inventor: TAKAHASHI YUTAKA
IPC: H01J23/26
Filed: 1979-12-24
Abstract: PURPOSE:To disperse the heat produced by a helix effectively by connecting  through a ribbon metal plate with a vacuum container or a metal cylinder in order to braze directly with a metal having excellent heat conduction. CONSTITUTION:A helix 1 is supported by a dielectric rod 2 while the dielectric rod 2 is secured through a metal ribbon 4 to a metal cylinder 3, where the dielectric rod 2 is completely secured with the metal ribbon 4 through brazing. The distortion or thermal stress at the securing section is released by plastic deformation of the metal ribbon 4 to prevent the deformation or breakdown of the dielectric rod 2. Consequently the contact heat resistance is eliminated by complete securing between the dielectric rod 2 and the metal ribbon 4 to reduce the fluctuation of heat conduction characteristic from the dielectric rod 2 to the metal cylinder 3 resulting in the improvement of heat transmission effect.

Abstract: PURPOSE:To obtain a measuring device for the pressing force of seat belts which is designed to provide always constant measuring conditions simply when held in place between the passanger's chest and an outer belt by detecting the curving of a leaf spring as a change in the electric resistance value of strain gages. CONSTITUTION:If the bottom part of a box body 15 as a base is placed on the chest and an outer belt 3 is supported on a guiding member 22 slidingly, the tension of the belt 3 is acted as pressing force upon the member 22 by the winding force of a retractor 2, by which a leaf spring 13 is deflected. If the size of the spring 13 is so determined beforehand that the spacing S between the bottom of the body 15 and the member 22 attains a reference size in this time, the tightening force of the belt 3 is detected by the rate of deflection of the spring 13. The deflection of the spring 13 is detected as a change in the electric resistance value of strain gages 17 by a bridge circuit consisting of four pieces of strain gages 17.

Abstract: PURPOSE:To detect the rotational phase of a rotor by the small number of constitutional elements by allowing a counting circuit to count up clock pulses from a zero crossing signal of a reference sine wave up to a zero crossing signal of an output sine wave from a resolver. CONSTITUTION:An output signal C inputted from the counting circuit 3 to a latch circuit 7 is latched by the input of an output signal E from a comparator 6 and reset by a signal B generated from a zero crossing timing signal generating circuit 2. Thereby, a signal is outputted from the circuit 7 by the timing and size shown by a signal F. The amplitude of the signal F is proportional to the phase delay of an output sine wave from the resolver from a reference sine wave inputted to the resolver and its quantity is proportional to the rotational phase value of the rotor in the resolver. Thereby, the rotary phase value of a structure to be measured coupled with the rotor can be checked by reading the amplitude of the signal F.

Title: Switching control power supply
Inventor: NAKATANI MASAHIDE
IPC: H02M3/28
Filed: 1993-07-08
Abstract: PURPOSE:To protect a switching element positively against breakdown due to overcurrent by interrupting the conduction on the primary of a transformer upon detection of an abnormal state where a pulse signal is sustained at the same level for a predetermined time or longer. CONSTITUTION:A pulse signal VG, is applied from a driver circuit 13 to the gate of a FET 12 which is thereby turned ON/OFF and an overdrive detection circuit 14 decides whether any abnormality is present or not with reference to the pulse signal VG received from the drive circuit 13 thus controlling an interruption circuit 15. When the pulse signal VG is kept at high level H due to a certain cause, a transistor 27 is sustained in ON state and a capacitor in an integration circuit 73 is discharged gradually and thereby the level of a signal Vovd lowers with time. When a predetermined time elapses with the pulse signal VG kept at high level H, Vovd drops below Vr and a signal Vstop makes a transition from L to H and then the interruption circuit 15 interrupts the connection between a DC power supply Vp and the primary winding N1 of the transformer 11.
