Title: Die casting machine
Inventor: NAKAMURA HIROMI
IPC: B22D17/20
Filed: 1984-05-25
Abstract: PURPOSE:To improve the quality of a product, etc. by disposing an exciter to the outside periphery of a plunger and vibrating a molten metal by means of the plunger. CONSTITUTION:The plunger 26 having a pressing head 24 is feely slidably inserted into the inside hole 20 of a sleeve 16. The exciter 38 is fixed via a spacer 36 to the outside periphery of the plunger 26. The exciter 38 consists of a cylindrical magnetic material. A resonator 46 attached to a shaft 24 and a coil 48 for high-frequency current are attached to the end thereof. The resonator 46 induces the high-frequency vibration of the same frequency and the vibration is transmitted via the head 24 to the molten metal 22 when the high-frequency current is passed to the coil 48. The molten metal 22 is thus admitted thoroughly into the fine gap parts of a cavity 18. The inside chamber 40 of the head 24 is cooled with water during this time and therefore the temp. elevation of the head 24 is obviated and the quality of the product is improved. The durability of a die casting machine is improved as well.

Title: Image converter
Inventor: ABUMI TAKAO
IPC: G09G5/00
Filed: 1985-05-17
Abstract: PURPOSE:To realize the coincidence of a position relation in a horizontal direction by synthesizing a signal outputted from a monitor television with an RGB signal from a computer through a delay line having the same delay quantity as an internal delay line. CONSTITUTION:A detecting output S1 which is amplified and detected at a video intermediate frequency PIF circuit 4 in a monitor television 2 is inputted to a chrominance component process circuit 5 and a luminance signal process circuit 6. A signal S2 color-processed at the circuit 5 is macro-demodulated at a macro demodulation circuit 7. A signal, the luminance signal component of which is separated, is delayed by 0.6musec approximately at a delay line 8 and is inputted to a matrix circuit 9 along with the signal S2 and converted to the RGB signal and is inputted to a cathode ray tube 10. A video converter 1 is equipped with a delay line 13 which delays the signal S1 by 0.6musec approximately and a synthesizer 14. So that an RGB signal S5 outputted from a computer 3 is already inputted delaying by a delay quantity equal to that of the delay line 8, the position relation in the horizontal direction is equal to the same one on the monitor television 2.

Abstract: PURPOSE: To improve transmitting efficiency of rotary driving device in which revolution of driving device is selectively transfered to 1st and 2nd rotary follower via idler, by increasing pressure between idler and each rotary follower.  
     CONSTITUTION: When a driving rotating unit 9 turns to the direction of a, a friction member 11 which rotates with a center shaft 10 of the rotating unit 9 as a fulcrum rotates to the same direction and an idler arm 12 in engagement with the friction member 11 follows in turning and puts an idler 4 to one of rotary follower 1 and the driving rotating unit 9 and rotates rotary follower 1 to the direction of A. While the idler 4 is pressed to rotary follower 1, the friction member 11 slides with the driving rotating unit 9. Then rotating power of the friction member 11 obtained by friction between the driving rotating unit 9 and the friction member 11 drives the idler 4 and becomes pressure to rotary follower 1, and thus power is surely transmitted to rotary follower.

Title: Insulator contamination detecting apparatus
Inventor: SAITO MUNECHIKA
IPC: G01R31/12
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To grasp the meaning of the contaminated situation of an insulator at an early stage by constantly monitoring the contamination of the insulator by an insulator contamination detecting device of a simple constitution. SOLUTION: This insulator contamination detecting device is constituted of a detection current transformer for detecting a current flowing through an insulator 1, and a determination means 5 for detecting a partial discharge pulse current from a measured current by the detection current transformer, to determine that the insulator has been contaminated when the pulse current is detected. As insulation performance is deteriorated by contamination of the insulator 1, partial discharging is generated before a discharge current is generated. By detecting the pulse current by this partial discharging, the contamination of the inusulator 1 can be detected before the discharge current is generated.
