Filed: 1980-06-27
Abstract: PURPOSE:To quantitatively identify the degree of resin impregnation and to improve reliability by detecting the amount of a variation in earth capacity for static electricity whereby the resin injection speed is controlled by the amount and switching is made from decompression injection to pressure injection at a specific value or more. CONSTITUTION:A detector 8 for earth capacity of static electricity is connected through an iron core 4, a coil 3, and lead wires 6, 7 housed in an impregnation tank 1. An impregnation controller 9 and a decompression and pressure controller 17 are connected to the detector 8 to control each valve 13, 14, 19, 21. Firstly, resin is supplied by reducing pressure from a resin tank 16 through a decompressor 22 and injection speed is controlled by adjusting the valve 13 in accordance with the present amount of a variation in earth capacity for static electricity. When the amount of a variation in earth capacity for static electricity exceeds 1.4 times or more, switching is made from the decompressor 22 to a pressure device 23 and the valve 14 is adjusted to supply resin by applying pressure and resin impregnation treatment is performed.

IPC: B41J2/05
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain a system wherein a tendency to heat-building up is more reduced during the long-term use of a printing head.

Title: Planar speaker
Inventor: TERAGAKI TAKESHI
IPC: H04R7/04
Filed: 1987-04-11
Abstract: PURPOSE:To prevent a sound wave from being diffused to the circumference of a diaphragm by providing many ribs for maintaining air including the sound wave in the front face of the diaphragm for a plane speaker and feeding forward and opening the rear face side of an enclosure. CONSTITUTION:A middle pitched sound area and a middle and low pitched sound area components are inputted to a voice coil 15 and a high pitched sound area component is inputted to a speaker 19 for a high pitched sound area. Then, the diaphragm 12 and the diaphragm of the speaker 19 are oscillated through the coil 15 and sounded. On the front surface and the side edges of the diaphragm 12, the ribs 14 are disposed and the upper and lower edges of the diaphragm 12 are curved to the front face side, so that, the air including the sound wave of the front face side of the diaphragm 12 is retained by the ribs 14 and pushed forward. The ribs play a role for reinforcing the diaphragm 12, however, it is too large to attain the role for rainforcing since it retains the air in the front face of the diaphragm and pushes forward. Accordingly, the sound wave is prevented from diffusing vertically and horizontally of the diaphragm or to the rear side.

Title: Multiplying-factor controlling device for scanning electron microscope or the like
Inventor: SAWARA KATSUJI
IPC: H01J37/28
Filed: 1981-06-10
Abstract: PURPOSE:To improve the frequency characteristic of a multiplying-factor controlling device, and enable a high-speed scanning by either changing the gain of an amplifier contained in a multiplying-factor controlling system circuit interlockingly with selection of the resistances of a variable resistance circuit, or changing the gain of the said amplifier by inserting another amplifier in series with the said amplifier. CONSTITUTION:An auxiliary amplifier 7, as illustrated in the figure, is installed between  an error amplifier 2 and a power amplifier 3. The gain of the amplifier 7 changes according to the resistance change-over carried out with a change-over switch (S) of a variable resistance circuit 5, and becomes larger as the resistance value of the circuit 5 is made smaller (as the multiplying factor is made lower). During the time when the multiplying factor is low, for example, when the resistance value is adjusted to (r1) by the change-over of the switch (S), the gain of the amplifier 7 changes into (G1) interlockingly with the above change-over. As the result, the frequency characteristic of the open loop gain of the multiplying-factor controlling system circuit is improved by a frequency of (DELTAf), as indicated by (Q1') in the figure, due to the above gain (G1). Consequently, a high-speed scanning of an over (f0) frequency is enabled even during the time of a low multiplying factor.

Abstract: PURPOSE:To improve the control characteristic of a load current control system at the current interruption time by switching a regulator from a PI regulator to I regulator when a load current is interrupted, and setting the integrating time of the I regulator in accordance with the conduction angle of the load current. CONSTITUTION:When a motor current is continuous, a current error signal from a differentiator 6 is inputted through a P regulator 13 and an interrupter 14 to an adder 15. On the other hand, the regulating output from the regulator 13 is inputted through a converter 12 to an I regulator 15. In this case, the PI regulation can be executed. When an interruption detector 11 detects the fact that the motor current is interrupted, the converter 12 is switched from the regulator 13 side to a gate alteration unit 8 side, and the interrupter 14 is switched from the continuous state to be the interrupted state. In this case, the I regulation is achieved. At this time, a gain alternation unit 8 varies a gain in accordance with the current amplification factor in response to a conduction angle theta.
