Abstract: PURPOSE:To measure the speed and torque of a motor by a no-load without using a flywheel, by measuring the pulse period of a pulse generator rotated by a motor to be measured, and calculating the speed and torque of the motor, based on said period. CONSTITUTION:When the motor 10 is started, the pulse generator 12 outputs a pulse P corresponding to the speed of the motor. A pulse period measuring circuit 13 measures periods t1, t2...tn extending from the start of the motor 10 to its completion, and they are stored in a storing circuit 14. An arithmetic circuit 15 calculates the speed N at every pulse by taking the reciprocal number of said period, and also, calculates pulse period differences DELTAt1-DELTAtn between respective pulses, from the periods t1, t2...tn. Also, based on a reference input circuit 16, a torque absolute value T in every speed at every pulse is calculated. Calculated speed N and torque T are outputted to a recorder 18.

When the temperature of the sight glass 6 rises to a certain value, the reaction product is prevented from occurring on and near the inner face of the sight glass 6 inside the chamber 1. In result, the reaction product is prevented from adhering to the sight glass 6. Therefore, the sight glass 6 is prevented from being clouded, and the etching depth can be accurately measured by the diffracted light through the sight glass 6.

Title: Semiconductor laser
Inventor: HIRATA SHOJI
IPC: H01S5/00
Filed: 1986-11-27
Abstract: PURPOSE:To obtain a distributed feedback type semiconductor laser having a current constriction effect and a refractive index guide effect by providing a distributed feedback means to a section, which is held by current constriction layers and in which there exists no current constriction layer. CONSTITUTION:Even when forward voltage is applied and conducted between both electrodes 18 and 19, currents arc interrupted and a current path is constricted into a groove 1a, in which there exists no current constriction layer 1, because the laminated structure of p-n-p-n structure is formed, aud the current path is limited. On the other hand, a refractive index in a guide layer 15 is selected at a large value in a distributed feedback means 2, and the guide layer 15 is brought near to an active layer 13 in the presence of a grating, thus elevating an effective refractive index. Since there exists the current constriction layer 1 having a large AlAs ratio and a small refractive index on both sides except the central stripe section, on the other hand, index difference is generated in the stripe section of the center and both sides of the stripe section, thus generating an index guide effect.

Title: Eddy current type noncontact displacement gage
Inventor: FUJITA TSUKASA
IPC: G01B7/14
Filed: 1990-10-18
Abstract: PURPOSE:To eliminate an error in an measured displacement amount owing to temperature change by applying AC current or voltage having two or more frequency components to an L element, separating it per frequency component and extracting and calculating an imaginary number part and a real number part. CONSTITUTION:Oscillators 24, 20 respectively output at frequencies (f), (nf), while they obtain outputs via voltage/current converters 22, 26 from a current synthetic circuit 28, which are to be applied to a detecting head 30. The head 30 has a coil 8 with inductance L1 and a resistance value R1 and separates voltage across the coil 8 respectively into frequency components (f), (nf) via a buffer amplifier 32 and further by synchronous wave detectors 34, 36. For example, pulses based on the output of the oscillator 24 are shifted by 90 deg. by a phase shifter 40 to extract only an imaginary number part, while simultaneously pulses based on the output of the oscillator 20 are shifted by 90 deg. by a phase shifter 38 to extract only an imaginary number part. Then an output of the synchronous wave detecting circuit is inputted to a subtraction circuit 44 as predetermined and applied to a linearizer, whereby voltage in proportion to a distance between an object and the head 30 can be obtained. Since a calculation base does not depend on a L1 value or R1 value of the head, no error occurs due to change in their temperatures.

Abstract: PURPOSE:To cause a shifter to move speedily and precisely by arranging it so that a shifter composed of cylindrical paramagnetic material can be shifted while it is rolled form the receiving surface of other stator to the pole surface of one stator by the conduction of current to a coil. CONSTITUTION:When a coil 2 of one stator 11 is turned on, and a coil 2 of the other stator 12 is not turned on, a shifter 3 is in a position indicated by a solid line because a magnetic attraction force exerts only between one stator 11 and a shifter 3. Next, when a coil 2 of the stator 12 is turned on at the same time a current to a coil 2 of the stator 11 is cut, a magnetic attraction force of the stator 12 is generated at the same time the magnetic attraction force of the stator 11 is erased. Therefore, the stator 3 leaves the pole face while rolling and stops at a place in contact with other pole face, and is held in the stator 12 by a strong magnetic attraction force.
