Title: Alternating current amplifier
Inventor: SATOU TAKASHI
IPC: H03F1/02
Filed: 1979-04-12
Abstract: PURPOSE:To establish the AC amplifier fast in the leading of the operation after power supply ON, by connecting the input terminal of the operational amplifier operated with a single power supply at the middle point of the power supply dividing resistor in AC manner. CONSTITUTION:The power supply Vcc is fed to the operational amplifier A and added to the voltage dividing resistors R1 and R2. The potential of the resistor junction point a is Vcc/2 and this potential is fed to the non-inverting terminal of the operational amplifier A via the resistor R3 together with the signal input V1. On the other hand, the inverting input terminal of the amplifier A is connected to the point (a) via the series circuit of resistor Rs and capacitor Cs. Where the feedback resistor Rf and the resistor Rs are equal, the DC amplification factor is 1, the DC level of the output terminal (b) is Vcc/2 and the voltage to the capacitor Cs is substantially zero. Accordingly, since the charge time of the capacitor Cs is zero, this circuit is the amplifier faster in leading time.

Title: Heat insulating material and its using method
Inventor: ARAI TAKASHI
IPC: B32B5/24
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the working property by covering at least both sides of an inorganic fiber heat insulator with a moisture-permeable waterproof sheet. SOLUTION: An inorganic fiber heat insulator 2 is sealed in a bag made of a moisture-permeable waterproof sheet 3 comprising a porous film 4 and a permeable mesh matter 4 consisting of thermoplastic resin laminated on at least one side thereof to constitute a heat insulating material 6. Since the sheet 3 is hardly permeable of water drop but permeable of moisture, and passes the interior side steam leaked to a wall body to the outside, dew condensation in the wall body can be prevented. Further, since the heat insulator 2 is sealed in the bag made of the sheet 3, the inorganic fiber is never scattered, and no uncomfortable feeling is given to a worker. When the heat insulating material 6 is put in an airtight plastic bag, and degassed to reduce the thickness, the storage and transportation are facilitated.  Although the heat insulating material 6 sucks air when taken out from the airtight bag in construction, the compressed body is held since the form is gradually restored, and the setting work is facilitated. Accordingly, the construction can be easily performed.

Title: Contactless switch
Inventor: TAKEGAHARA IKUO
IPC: H01H55/00
Filed: 1990-02-28
Abstract: PURPOSE:To enhance the contacting reliability of a contact of a switch and prolong its lifetime by entering a pulse signal which is generated by a magneto- striction pulse generating element when a relative displacing mechanism causes relative displacement of a magnetic circuit with a magnetism generating means. CONSTITUTION:When a push button 8 is pushed to cause contraction of a compression spring 6, and a permanent magnet 4 is put in the condition that its N pole contacts a Wiegand element 30 while the S pole touches No.2 yoke 22. Thereby a magnetic path is formed by the element 30, yoke 22, and magnet 4, wherein the direction of the magnetic field is reversed within the element 30 to be headed to the yoke 22 from the element 30. Because the direction of the magnetic field is reversed, positive pulses are generated at the two ends of a coil 33. When the push button 5 is released from the pushing, the permanent magnet 4 is restituted. Accordingly the direction of magnetic field is reversed, and negative pulses are generated at the ends of the coil 33.

Title: Method and device for positining control
Inventor: YOSHIDA KOJI
IPC: G05D3/12
Filed: 1992-03-03
Abstract: PURPOSE:To execute the positioning of finite time matching having no residual oscillation by making posicast control into a closed loop and executing feedback control while following up a semi-elliptical track for which the phase place track starts from the origin of displacement/velocity 'zero' and the displacement ends at the point of a target value/velocity 'zero'. CONSTITUTION:A track function generator 1 generates a track function v=f (x) having displacement (x) as the parameter so as to be started from an initial state (x0, v0) on the phase plane and to turn velocity (v) to zero at a target value xc, and controls the phase plane track so as to follow up this track. Deviation between a velocity command value vc obtained from the displacement (x) and the target track function f (x) generated by the track function generator 1 and the measured velocity value (v) differentiating the position (x) detected by a linear stage 5 at a differentiator 4 is fed back through a proportional element 3 by a control system and impressed to the linear stage 5 as a power command. Thus, even when the system characteristic is fluctuated or is non- linear, the positioning of finite time matching having no residual oscillation is precisely enabled at high speed.

Title: Circuit for stabilizing semiconductor laser output
Inventor: YAMAMOTO SHIYUU
IPC: H04B10/07
Filed: 1980-04-10
Abstract: PURPOSE:To stabilize the light signal output and the oscillation wavelength for PCM communication or the like by a method wherein the temperature of the laser element is detected by an interface voltage and the control of the temperature and the stabilization of the interface voltage are performed by said detected output. CONSTITUTION:A temperature controlling circuit 1a is attached to a circuit adapted to take out a light signal from a laser element 3 by direct modulation of a bias current applied thereon with a driving circuit 1. This circuit subtracts a drop in the voltage due to a series resistance component RS of the element from the terminal voltage thereof and detects an interface voltage V which is amplified and detected to obtain a DC bias component. A differential signal between the DC bias component being amplified and detected and the reference voltage activates a temperature controlling element 8. This can stabilize the temperature of a laser element 3 to ensure a stable light output thereby preventing changes in the oscillation wavelength other- wise caused by variation of the temperature. The stabilization circuit is added with a circuit adapted to control the amplitude of a driving pulse current by detecting deterioration in the pulse amplitude with a light output behind the laser element 3 to stabilize the output against secular change of the element.

Abstract: PURPOSE: To properly connect an electronic part without inclination by providing such a constitution that the height of a conductor stud pressed and installed into a specified conductor plate is set to be substantially equal to the surface of the conductor plate of the outer layer on the side which the conductor stud faces. CONSTITUTION: A conductor plate 1 has an installing hole 1A in a required part, and the foot part 4B of a conductor stud 4 formed of copper or brass is pressed into the hole 1A to form a down terminal part. The stud 4 has an inserting hole 4A for inserting the terminal of an electronic part in the center part. Since the area of an insulating material 2 in the installing part of the stud 4 is properly removed, and an escape hole 3A of a proper size is provided in a position where the conductor stud 4 is situated in a conductor plate 3 of the second layer, the conductor stud 4 is electrically fixed only to the conductor plate 1, and never make contact with the conductor plate 3 of the second layer.  Further, since the outer surface of the stud 4 is constituted so as to have substantially the same height as the outer surface of the conductor plate, the electronic part is never mounted with inclination even when the terminal of the electronic part is connected to the stud 4 and the conductor plate 3 of the second layer.
