Abstract: PURPOSE:To improve the mechanical life of a chip by raising the bulk of a chip bonding portion, thereby absorbing a stress due to the difference of a thermal expansion coefficient between a substrate and the chip. CONSTITUTION:A frame 10 has a permanent magnet 7 magnetized elevationally, a temperature sensitive magnetic material 8 laterally opposed in the magnetizing direction and a soft magnetic material 9 having wider width than both and integrated oppositely. A Permalloy film 6 of approx. 5mum thick is formed on the back surface of a chip 5, and the chip height after bonded to a substrate 2 becomes approx. 1mm. When the frame 10 is coated with the chip 5 disposed in advance at a center and passed through an electric furnace, a solder ball is melted to bond the substrate 2 to a bump 3, and the magnetization of the material 8 is inverted from horizontal to vertical direction. Accordingly, the material 9 is also magnetized to form a magnetic circuit for coupling the material 9, the film 6 and the material 9. Thus, the chip 5 is attracted to the material 9, and raised by 0.5mm. When the chip 5 is removed from the furnace in this state, the solder ball is solidified in the state as it is. Therefore, the ball 12 is secured in the elongated state.

Title: Pulse width modulation drive circuit of dc motor
Inventor: MAKI SHINICHI
IPC: H02P6/08
Filed: 1990-03-02
Abstract: PURPOSE:To reduce noise of a motor to be small by making the frequency of a PWM signal larger sufficiently than that in an audible band by a simple circuit construction without using a high-speed microcomputer. CONSTITUTION:A PWM signal outputted by a microcomputer(MC) 11 is integrated by a circuit constructed of a resistor 25 and a capacitor 26 and enters an inversion input terminal of a comparator 27. A clock of several megahertz outputted by an oscillator 20 is subjected, together with the signal of the MC 11, to frequency division in a frequency divider 28 and made to be a rectangular wave of a frequency fh being larger sufficiently than the one in an audible band. This rectangular wave is turned into a triangular wave by an integrating circuit and enters a non-inversion input terminal of the comparator 27. The comparator 27 compares the triangular wave with the integral wave, generates a high frequency PWM signal having the frequency fh and supplies it to a control circuit 12. The pulse width of the high-frequency PWM signal enables execution of a control of rotation of a motor 10 as usual, when a switching signal is generated in accordance with the PWM signal generated by the MC 11 and outputs of Hall elements.

IPC: E21C37/00
Filed: 1993-02-18
Abstract: PURPOSE:To ease the service conditions of a static crushing agent by filling up this static crushing agent in a hole formed in a brittle body such as concrete lumps, stones and rocks or base rock or the like, and improving the extent of operability in a crusher which pours water into this hole and thereby hydrates this crushing agent. CONSTITUTION:A water storage part 1, which had such a volumetric capacity as sufficient enough to hydrate a crushing agent D filled up in a hole C and another capacity capable of checking a spout of this crushing agent D due to abnormal reaction, is formed there, and then a throttle hole 2 is formed in a bottom part 2a of this water storage part 1. In addition, a specified length cylindrical part 3 is formed there in surrounding this throttle hole 2 beneath the bottom part 1a. When a crusher A is installed in the hole C and water is fed thereto, this water flows down natually from the hole 2 and poured into the hole C. After a water level in this hole C goes up and a tip of the cylindrical part 3 is closed, and when it further goes up, internal pressure in this cylindrical part 3 goes up as well. When the internal pressure in the cylindrical part acting on the throttle hole 2 and hydraulic pressure in the water storage part 1 are equilibrated, water injection is stopped, whereby such a water quantity as capable of checking any spout due to abnormal reaction is left behind.

Title: Alarm controller
Inventor: NAKADA YUJI
IPC: H02J13/00
Filed: 1989-03-03
Abstract: PURPOSE:To facilitate accurate judgement of an operator by limiting individual occurrence of abnormal alarm, upon occurrence of frequency drop approximately over the entire region of the power system for a plant, and outputting only the frequency information. CONSTITUTION:Upon provision of abnormal information from a communication unit 1 in a power system, abnormal information is produced and fed to an alarm generating section 5. On the other hand, system frequency is monitored at a frequency monitoring section 4 through a frequency converter 3, and when frequency drop is detected approximately over the entire region occurrence of frequency drop is informed the alarm generating section 5. When frequency drop does not occur, the alarm generating section 5 outputs individual alarm through an alarm processing section 6 and displays 7 the individual alarm. Upon occurrence of frequency drop, the alarm generating section 5 energizes an alarm limit mode section 9 to limit output of the alarm, while the alarm processing section 6 outputs frequency information and displays 7 the frequency information. By such arrangement, the operator can make judgement accurately and can start recovery operation quickly.
