Title: Distributed feedback type semiconductor laser
Inventor: HIRATA SHOJI
IPC: H01S5/00
Filed: 1990-02-26
Abstract: PURPOSE:To suppress the occurrence of side modes by arranging the coupling coefficient of a grating so that it may change gradually toward both end faces or their vicinities in the longitudinal direction of a laser oscillator and near zero, and putting both end faces of the laser resonator in nonreflecting conditions, and shifting it by a specified phase. CONSTITUTION:By applying treatment such as the anisotropic etching or the like with the photoresist as a mask, it is made so that the amplitude may change gradually toward, for example, both ends 6 or their vicinities and near zero, whereby the coupling coefficient is made to gradually change toward both end faces 6 and their vicinities and near zero. Thus a grating 4 is made in the guide layer 3 having the specified thickness d. Furthermore, this grating 4 is made into such a structure that the phase is slid by lambda/4 at, for example, the center so as to get lambda/4 phase shift, or that lambda/4 phase shift is done equivalently by changing the propagation constant. And second clad layer 5 is grown extensively on this grating 4, and then after forming a cap layer, an electrode, etc., it is put in nonreflecting conditions at both end faces 6 so as to get a DFB laser.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To control the speed of an AC motor with a DC speed reference by providing a linking operation unit and an insulating amplifier with a filter circuit. SOLUTION: A DC speed reference provided from a DC speed setter 1a is fed through a speed control amplifier 1b to generate a current reference which is then fed through an amplifier 1c to each insulating amplifier 2a. An insulated current reference from the insulating amplifier 2a is fed through a current control amplifier 2b to generate a voltage reference which is then fed through a voltage control amplifier 2c to a DC motor 3. A current reference, from which ripples are removed through the insulating amplifier 4a with a filter circuit in a linking operation unit 4, is inputted through an amplifier 4b to each insulating amplifier 5b of the AC motor side thence outputted through an AC motor controller 5c to an AC motor 6 for the purpose of linked operation.  Since no speed reference is inputted to an insulating amplifier 5a, a speed reference is generated from a simulated speed reference circuit 5d.

Abstract: PURPOSE:To automatically judge skewing of charged paper, by using a printing head feed mechanism as the mechanism of an image sensor. CONSTITUTION:For example, an amorphous silicon image sensor 3 is mounted to a carriage 1 moving in direction X1, X2 latelally in a line in close vicinity to the printing head 2 provided to the inner side surface of said carriage 1. The left-hand end part of paper 16 is read by the image sensor 3.

Title: Auto tracking circuit
Inventor: NISHIJIMA HIDEO
IPC: G11B5/592
Filed: 1984-03-12
Abstract: PURPOSE:To limit the range of the output voltage of an auto tracking circuit and to prevent deterioration in the performance of an electromechanical transducing element by setting the displaceable range perpendicular to the rotating surface of a rotary head to + or -0.5-+ or -1 track pitch, and displacing the rotary head by one track pitch within the displaceable range when the head reaches a limit of the displaceable range. CONSTITUTION:When the rotary head is in the best tracking state and an envelope signal (c) has a maximum amplitude, a mode setting signal (j) is inverted every time the rotary head scans a magnetic tape and an up/down counter 38 counts up and down repeatedly, so that the rotary head is displaced by one step and returned repeatedly. There is at least one displacement position where the rotary head is in the best tracking state within the displacement range of the + or -0.5-+ or -1 track pitch of the rotary head, and this operation sets the rotary head at the displacement position. Consequently, a DC voltage applied to the electromechanical transducing element is reduced.

Title: Pll circuit having plural voltage-controlled oscillators
Inventor: ITOU AKIHIKO
IPC: H03L7/08
Filed: 1981-03-30
Abstract: PURPOSE:To obtain plural output signals having oscillation frequencies or duty cycles by providing a PLL circuit with voltage-controlled oscillators which differ in time constant, and allowing one of those oscillators to drive the other voltage- controlled oscillators by its output control voltage. CONSTITUTION:A PLL circuit consists of a phase comparator 1 receiving an input signal, a loop filter 2, and voltage-controlled oscillators 3-i (i=1-n) driven by its output control voltage V. The output of the oscillator 3-1 is phase-compared with the input signal by the comparator 1. When the output of Schmitt trigger circuit 6i of the oscillator 3-i is at a level H, a switch SW7i is closed to charge a capacitor Ci with a current from a contant current source 4i, thus raising a voltage at a point Ai. When the voltage at the point Ai reaches a high threshold value, the output of the circuit 6i is inverted to a level L and while the SW7i is opened, a SW8i is closed to discharge the Ci through a constant current source 5i; when the voltage at the point Ai reaches a low threshold value, the output of the circuit 6i is inverted again to a level H, and this operation is repeated to perform oscillation. The oscillation time constants of respective oscillators are made different to output signals having different frequencies.

Title: Production of foamed aluminum
Inventor: IMAGAWA KOUJI
IPC: C22C1/10
Filed: 1979-04-13
Abstract: PURPOSE: To easily manufacture a foamed Al alloy of excellent quality, by adding fine powder of a synthetic calcium silicate hydrate to a molten Al alloy whose viscosity is increased by blowing air thereinto.  
     CONSTITUTION: Air is blown into a molten Al alloy to increase its viscosity to 3W 15 times. 3W20wt% of a synthetic calcium silicate hydrate (XCaO, YSiO 2 , ZH 2 O) with a grain diameter of 0.1W100μ is added to the molten alloy. The synthetic calcium silicate hydrate is easy to change into a carbonate. Therefore, a more effect can be produced if some calcium is changed into CaCO 3  by an appropriate quantity of carbonating treatment after hydrothermal synthesis in an autoclave. The hydrate almost instantaneously releases its crystal water and CO 2  in the molten material so that bubbles are present in the Al alloy when it is solidified. This results in providing a foamed Al alloy which has a porosity of 90% or more and small weight and excels in sound and impact absorption.
