Title: Method for sealing projection nut
Inventor: AOYAMA YOSHITAKA
IPC: B05D7/14
Filed: 1986-11-29
Abstract: PURPOSE:To prevent a painting material from penetrating in a screw hole and to impart waterproof effect, by welding a projection nut and injecting a sealer in the nut on the upper side thereof to close the screw hole. CONSTITUTION:A sheet metal part 6 having a hole is placed on a fixed electrode 5 having a guide pin 4 and a projection nut 3 equipped with a welding projection 7 is positioned so as to be mounted thereon. Since the length of the guide pin 4 penetrating in a crew hole 8 is shorter than the overall length of the screw hole 8, predetermined cavity is formed by the screw hole 8 and the guide pin 4. A sealer passage 10 is provided to a movable electrode 9 forming a pair along with the fixed electrode 5 and, after the movable electrode 9 falls to complete the welding of the nut 3, a soft and viscous sealer 12 is pressed to be injected in the screw hole 8 and the upper part of the screw hole 8 is brought to a closed state.

Title: High-voltage power device
Inventor: ARIKAWA SUMITAKA
IPC: H02M7/48
Filed: 1994-11-18
Abstract: PURPOSE: To superpose an AC voltage only by the use of cheap parts such as diodes, resistors, capacitors, etc., by applying AC current capable of passing through a low-pass filter to a divided point of a smooth voltage generated by the low-pass filter. CONSTITUTION: A low-voltage DC signal is switching-controlled and converted into a low-voltage AC signal by a switching circuit 1. This low-voltage AC signal is boosted by a high-voltage transformer 2, and converted into a high- voltage AC signal. Furthermore, the high-voltage AC signal is rectified and smoothed by a rectifier circuit and a low pass filter 3 to obtain a high voltage DC signal. The high-voltage DC signal obtained by smoothing is divided by resistors R1 and R2 . The switching circuit 1 is controlled by a feedback circuit 5 so that the voltage at a voltage-divided point 4 by resistors R1 and R2 may be constant. And an AC power source 13 is provided for applying AC current having a frequency component capable of passing through a low-pass filter to the voltage divided point 4. Consequently, an AC superposed voltage can be obtained.

Title: Television signal output circuit
Inventor: KIRIYAMA TAKASHI
IPC: H04N5/14
Filed: 1989-11-02
Abstract: PURPOSE:To output an analog television signal which does not contain a DC component by means of a simple circuit without using the capacitor of a large external form by providing a comparator which compares the output of an amplifier with a reference voltage through a first low pass filter circuit, sets the output to be an open state if they are equal, outputs a positive voltage if it is large, and a negative voltage if it is small, and a subtraction circuit to which the output of the comparator is inputted through a second low pass filter circuit. CONSTITUTION:A value from which a difference is not outputted is set to be the reference voltage of a comparator 5. A judgement signal (c) outputted from the comparator 5 compares the waveforms of an integrated pulse (b). When the integral pulse (b) is higher than the reference voltage, the positive voltage is outputted. When it is lower, a negative voltage is outputted. At that time, the output of the comparator 5 is set to the open-state and is set to be a high impedance output (the part of A in a graphic) at the time of the reference voltage. Since an analog television signal (e) contains the direct component shown in B in the graphic, the analog television signal (e) and a DC component removal signal (d) are inputted to a subtraction circuit 2. When the difference of the signal (d) is take from the signal (e), it comes to an analog television signal (f) which does not contain the DC component. Thus, an analog television signal (a) which does not contain the DC component on an average can be obtained through an amplifier 3.
