Patent JP-H04369105-A (JP)
Title: Amplifier
Inventor: INOHANA HARUYUKI
IPC: H03F1/32
Filed: 1991-06-17
Abstract: PURPOSE:To reduce distortion without increasing a feedback quantity of an output signal to an input stage. CONSTITUTION:An output of differential amplifier circuits 3,9 amplifying a difference between input and output signals of the amplifier circuit with an amplification factor almost equal to the unity is added to the input signal by an adder circuit 8 and the result of the sum is used for the input to the amplifier circuit 4. Thus, distortion of the amplifier circuit is eliminated and the input signal and the output signal are made coincident. Thus, when this invention is applied to an amplifier having a feedback loop, low distortion is attained without increasing the feedback quantity.

Title: Black body
Inventor: HARA HIROICHI
IPC: G01J5/02
Filed: 1991-06-17
Abstract: PURPOSE:To obtain a calibration black body with emissivity improved by providing a groove whose depth size is several times its widthwise size between adjacent pyramids. CONSTITUTION:A calibration black body 30 has grooves 31 at positions between adjacent pyramids 21, that is at portions of recesses 23, while the grooves 31 are, when viewed from above, formed in a grid in X-and Y-directions. The groove 31 is 0.1 to 0.2mm in width and 0.5 to 1.0mm in depth which is approximately five times the width. Infrared rays 22-1 incident to a slope of the pyramid 21 are reflected three times while infrared rays 22-2 incident between the adjacent pyramids 21 enter the groove 31. Since the groove 31 is narrow and deep, the infrared rays 22-2 are reflected on one of sides 31b before reaching the bottom 31a then reflected on the bottom 31a, further reflected on the other side 31c, and then returned out of the groove 31. Therefore the calibration black body 30 has improved in emissivity as regards portions between the adjacent pyramids 21 thereby providing high emissivity.

Title: Terminal voltage detector of thyristor motor
Inventor: NAGASE HIROSHI
IPC: H02P6/16
Filed: 1977-12-05
Abstract: PURPOSE: To drive an AC motor by making both half-waves of the terminal voltage obtainable from analog switches to the same polarity and adding the same.  
     CONSTITUTION: The terminal voltage introduced with a transformer 4 contains power source rectifying ripples and the output signal of a position detector 3 is the sine wave of the same phase as that of the basic wave component of the terminal voltage. Since analog switches 6, 7 go ON and OFF respectively according to the output signals of comparators 9, 10, the output signals of the analog switches 6, 7 are of the same polarity with respect to the basic wave component of the terminal voltage and become the signals which are alternately outputted. When the output signals of the analog switches are added with an operational amplifier 8, they become the signal having been rectified with respect to the basic wave component of the terminal voltage, thus receiving no effect of power source rectifying ripples.

Title: Magnetic recording and reproducing device
Inventor: SHIBATANI HIROMICHI
IPC: G11B5/02
Filed: 1993-05-26
Abstract: PURPOSE:To obtain a magnetic recording/reproducing device capable of detecting with a large signal amplitude against a noise. CONSTITUTION:An MR element 1, an inductance element 2 and a capacitance element 3 constitute a parallel resonance circuit as described in the figure and equivalently represent an impedance 4, then by combining it with capacitances 5, 6 and transistor 7, a colpitts type oscillating circuit is formed. When the equivalent impedance 4 becomes inductive by the change of a resistance R of the MR element, this colpitts type oscillating circuit is oscillated, thereby a sine-wave oscillating signal is obtained on an output terminal 8. When the equivalent impedance 4 becomes capacitive by the change of the resistance R, the colpitts type oscillating circuit is not formed and the oscillation is stopped, then the signal is not appeared on the output terminal. As the whole constitution, the resistance R is changed by magnetization of the medium such as a magnetic tape, etc., therefore, the oscillating state or the oscillation stopped state is formed in accordance with this change, and conversely the signal of the magnetic tape, etc., is detected from these states.

Title: Control system for field converter of separately-excited motor
Inventor: HASHIMA KESAO
IPC: H02P3/14
Filed: 1982-08-23
Abstract: PURPOSE:To improve the responsiveness of a motor when the motor is started by resetting the output voltage of a field converter to the output voltage necessary to flow a field current equal to the field current command value from the highest output voltage at the output voltage of a field converter when the field current becomes higher than the field current command value. CONSTITUTION:When a regenerative brake mode occurs, a field current instruction value iFP is set to the prescribed value, and a field converter 5 is controlled so that the output voltage e1 of the converter 5 becomes the highest voltage efmax. Thereafter, when the field current iF becomes higher than the field current command value iFP, the output voltage ef of the converter 5 is reset to the output voltage ef1 necessary to flow the field current substantially equal to the field current command value iFP from the highest output voltage efmax. In this manner, the responsiveness when the motor is started can be improved.

Title: Electrostatic chuck
Inventor: TOMARU KAZUHIKO
IPC: H01L21/3065
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of dust while the excellent cooling performance of an electrostatic chuck resulting from the good adhesion between a wafer and the chuck is maintained by successively providing a first insulating layer, a conductive pattern formed as an electrode, and a second insulating layer made of silicone rubber carrying a crimp pattern on its surface on a metallic substrate. SOLUTION: An electrostatic chuck is constituted by successively providing a first insulating layer 3 made of silicone rubber, a conductive pattern 6 formed as an electrode, and a second insulating layer 1 made of silicone rubber carrying a crimp pattern on its surface on a metallic substrate 5. In addition, the effective contact area of the chuck with a wafer is formed so that the area may become 20-90% of the whole area of the wafer. Consequently, the contact area of the chuck can be reduced effectively to a level at which the cooling performance of the chuck is not deteriorated and the adhesion of dust can be reduced. In addition, since the elastic silicone rubber is used for the insulating layers 1 and 3, the adhesion of the chuck with irregularities on the rear surface of the wafer is improved and the temperature of the wafer can be maintained uniformly.

Title: Removal of snow by sliding
Inventor: HONMA YOSHINORI
IPC: E04H15/02
Filed: 1991-05-23
Abstract: PURPOSE:To sufficiently secure the intensity of illumination in room by completely removing snow piled on film by using a comparatively small energy. CONSTITUTION:The central part of a film roof 1 with piled snow and one or two or more lines passing the central part are heated in a concentrated manner to divide the snow into snow blocks 2a and 2b, where snow-thawed water layers 3 are formed on the bottom of the blocks 2a and 2b. The water layer 3 is cooled to form frozen layers 4 on the bottom of the blocks 2a and 2b, and the blocks 2a and 2b are heated from the inside of the roof 1 to form a thin water layer between the layer 4 and the surface of the roof 1. Since the thin water layer acts like a lubricant, the frictional coefficient between both can be lowered to cause the blocks 2a and 2b to slide down the roof 1 quickly.
