IPC: H04R3/00
Filed: 1981-05-30
Abstract: PURPOSE:To control the directivity, by fixing plural speaker units for the same frequency band at proper intervals and giving a level difference, a time difference, and a phase difference to speaker units. CONSTITUTION:A woofer 2 is fixed in the lower part of the front of a speaker box 1, and one side in the upper part of the front is cut to form a slope 3, and tweeters 41 and 42 are fixed to the upper part of the front of the speaker box 1 and the slope 3. When a pair of speaker systems is so installed that tweeters 42 fixed to slopes 3 are placed nearer to walls of a listening room 6, tweeters 41 provided in upper parts of the front of speaker boxes 1 take charge of direct sound components to a listener 7, and tweeters 42 provided on slopes 3 take charge of reflected sound components. Attenuators 52 and 53 are operated to change input signal levels to tweeters 41 and 42, thus making them suitable for the sound absorptivity of walls or the like to obtain an optimum reproducing sound field. Delay elements are effective besides attenuators.

Title: Level gauge
Inventor: SEKIGUCHI MINEO
IPC: G01F23/36
Filed: 1979-07-03
Abstract: PURPOSE: To avoid the effect of the variation of the cover gaseous pressure for the liquid metal level gauge used in the liquid metal cooling fast neutron reactor, by incorporating plural number of detection systems into the barrel of the gauge to detect the operation of the level sensor part which operates by the variation of the buoyant force and then providing the vapor trap at the upper part of the detection system.  
     CONSTITUTION: The optional number of detecting parts 7 are incorporated into  level gauge 6 in the tank along with vapor trap 10 provided at the upper part each.  When liquid level 8 is lower than float 13 of part 7, the tip of operating bar 14 provided piercing through diaphragm 15 is apart from actuator 20 of limit switch 21 by  the empty weight of float 13. With increase of level 8, float 13 rises up to turn  switch 21 on. Thus the lamp glows to secure detection of the position of the liquid  level. As trap 10 is located apart from the detecting part, the liquid metal vapor  never reaches the switch part even though the pressure of the cover gas may increase. Thus the effect of the variation of pressure can be avoided.

IPC: H02K19/10
Filed: 1979-06-29
Abstract: PURPOSE:To easily increase the thrust for a moving member by forming projected and recessed strips loosely fitted maintaining predetermined gaps therebetween on the opposing surfaces of the stator and the moving member along the moving direction of the moving member. CONSTITUTION:When a current is caused to flow through an axiciting coil 5 and a magnetomotive force Mmf is acted upon a stator 1 and two magnetic poles, a thrust FM is acted on the moving member 2. When the opposing area of the stator 1 and the moving member 2 is denoted by SE, since the projected and recessed strips 8 and 9 extended along the moving direction of the moving member 2, and loosely fitted by maintaining gaps 3 therebetween, the area SE becomes larger than the area S in the case of having no projected and recessed strip if the outer diameter dimension is the same. Accordingly, when the space permeability is denoted by muO, the length of the gap 3 by g, and the opposing area by S, the magnetic energy WE in the gap represented by 1/2.muOS/g becomes larger than the area having no projected and recessed strips from the relationship of SE>S. By this arrangement, the thrust for the moving member is increased preventing the increase in the size of the motor.

IPC: G05F3/20
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To keep a substrate voltage to be a specific voltage level by using a level shifter including a band gap reference voltage. SOLUTION: In a substrate pumping system 200, a level shifter 210 includes a band gap reference device 215 outputting a voltage Vbq and an output Vsense is given to a noninverting input lead of a comparator 140. When the voltage Vsense is negative, a comparator 140 provides an output of a signal to an AND gate 120 to block a clock signal from an oscillator 110 thereby inactivating a capacitive charge pump 130. When the voltage Vsense is positive, the capacitive charge pump 130 pumps negative charges to a substrate in response to the clock signal passing through the AND gate 120 to reduce a substrate voltage VBB. The substrate voltage is kept to a specific voltage level by applying the clock signal to the capacitive charge pump 130 or stopping the clock signal from the capacitive charge pump 130 in this way.
