Title: Motor controller
Inventor: KAYAMA MASANORI
IPC: H02P29/00
Filed: 1985-03-29
Abstract: PURPOSE:To set current fluctuation approx. to be zero in case of current switch- over, by compensating speed bias content in case of the switch-over from current control to speed control. CONSTITUTION:In case of the switch-over from current control to speed control, normally opening contact points a1, b1, c1 are closed, and a normally opening contact point d1 is opened, but immediately before the switch-over, normally opening contact points X1, X2, X3 are closed. Speed bias content B is arithmetically operated by an arithmetic control section 7 under control conditions. Accordingly, in case of the switch-over from current control to speed control, the input of a speed command value V, actual speed Va, and speed bias B to an additional point 5 is provided. As the result, current fluctuation is not generated in case of the switch-over, and any trouble to be caused along with the switch-over is eliminated.

Abstract: PURPOSE:To suppress a side robe and to obtain a sharp directivity by constituting an acoustic tube of a rigid wall and a cylindrical hollow part so as to obtain a spherical sound wave and by providing a parabolic horn having a horn opening side focus vicinal position at the center of the hollow part. CONSTITUTION:An acoustic tube 11 consists of an arbitrary rigid wall 11a and a cylindrical hollow part 11b and positioned forward an electro-acoustic transducing element consisting of a piezoelectric element 1 and a diaphragm 2. Assuming that a radius and a length of the hollow part 11b are r and l, respective ly, the following relation is established: 2r<=0.586<1/2>.lambda, l nlambda/2-k.r (n: positive integer; k: constant 0.65), whereby a stable spherical wave is formed by using the hollow part as a center. Furthermore a center at the side of an end 11c of the hollow part 11b is positioned in a horn opening focus point vicinal position including a focus position on a horn shaft of a parabolic horn 5. As a result, the spherical wave transmitted to the outside propagates in parallel with the horn shaft in the parabolic horn 5, and the sound wave propagating outside has a sharp directivity.

Title: Bias circuit for cmos amplifier and method for adjusting channel length of mos transistor in the bias circuit
Inventor: RI KOSO
IPC: H03F1/30
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To maintain constant the level of performance of an analog/composite mode circuit, such as a CMOS operational amplifier and a comparator by selectively adjusting the channel length of a transistor or the like constituting a bias circuit, even if a power supply voltage arbitrarily changes from 3 V to 5 V level. SOLUTION: A transistor having a short channel length or the like is used for a part to directly drive an amplifier, and a transistor having a long channel or the like is selectively used for other parts. Thus, a short-channel effects can be reduced, and almost a constant performance can be obtained with respect to the changes of a power supply voltage. In this method for adjusting the channel length of the transistor applied for an amplifier bias circuit, the short- channel effects or current mismatching or the like is reduced, so that bias currents which are independent of power supply voltage is obtained.

CONSTITUTION:A beam of light(continuous line) with incident angle theta0-8g is converged at a position of focal point 11 by using all mirrors 1a-1b of a main reflecting mirror 1 and a part 2a-2b of a sub reflecting mirror. Also. a beam of light(dotted line) with incident angle theta0 is converged at a position of focal point 12 by using all the mirrors 1a-1b of the main reflecting mirror and a part 2b2c of the sub reflecting mirror 2. In a two-dimensional mirror surface with such geometric arrangement, beams in two different directions of -theta0 and +theta0 can be formed by placing a wave source at the position of focal points 11, 12, respectively. In addition to that, the beam accompanying deterioration of characteristic in a range allowable in practical use can be formed in a direction of -theta0<theta<+theta0 between two directions from the beam in the direction of -theta0 or +theta0. In other words, it is possible to deviate the beam within a range of -theta0<theta<+theta0.

IPC: G01B11/00
Filed: 1995-03-27
Abstract: PURPOSE: To prevent the measurement error in the amount of travel of a speckle pattern, and further in a displacement information even if the base line of speckle pattern data is inclined according to irradiating laser beams and the surface state of a sample to be measured by allowing an operation means to differentiate the speckle pattern data and obtaining a peak position. CONSTITUTION: When obtaining the displacement information of a sample W to be measured by obtaining the amount of travel of a speckle pattern, each speckle pattern data are differentiated once and then the cross-correlation function is obtained for calculating a peak position or the cross-correlation function of each speckle pattern data is obtained and at the same time the function is differentiated twice for calculating the peak position. Therefore, even if the speckle pattern does not have a uniform intensity and the base line is inclined owing to, for example, the condition of irradiating laser beams and the surface state of the sample W, no calculation error of the peak position caused by the inclination is generated, thus constantly and accurately obtaining displacement information.

Title: Sequence control camera by electric power mirror
Inventor: KITAHARA TOSHIYUKI
IPC: G03B19/12
Filed: 1979-05-31
Abstract: PURPOSE: To make time scheduling possible without using any switch by sequence controlling an exposure information control circuit by the sequence signal based on the sensing electric signal corresponding to the operation of the electric power mirror.  
     CONSTITUTION: When a motor 10 runs upon closing of a switch S 3  according to shutter release, a mirror is kicked up by a belt. The hole provided by the belt is then detected by photo transistors (TR) 14, 15, and the TR14 goes from ON to OFF. The detection electric signal corresponding to this mirror operation causes an AND gate to be opened by an inverter so that the latch to a latch circuit 29 of photometric exposure information is activated. On the other hand, the photo TR15 conducts upon completion of the kicking-up of the mirror to stop the motor 10 and a solenoid L 1  for releasing the stopping of the front curtain is energized by a shutter second time control circuit 30, thus the time scheduling is accomplished without using any switch. The need for allowance time by switch time, etc. is eliminated.
