Title: Apparatus for measuring semiconductive laser spectrum
Inventor: MORI KAZUKOTO
IPC: G01J3/10
Filed: 1985-10-19
Abstract: PURPOSE:To allow laser beam to be accurately incident to the end surface of the optical fiber connected to a beam spectrum analyzer, by performing the positional control of a lens on the basis of the output difference of a plurality of photodiodes to which laser beam is incident. CONSTITUTION:Laser beam emitted from a semiconductive laser device 1 passes through lenses 3, 4 and half mirrors 5, 6 to be condensed to the end surface of an optical fiber 2 and the spectrum thereof is measured by a beam spectrum analyzer 12. At this time, the laser beam reflected by the half mirror 6 is incident on a PIN photodiode 9. This photodiode 9 is divided into four sections and the difference signal of the respective output voltages of the divided photodiodes is applied to an automatic position controller 7 and the position of the lens 3 is adjusted so that a light emitting spot is positioned at the center of the photodiode 9. Further, by measuring the difference between the current values of four divided PIN photodiodes by an ammeter 11, the positional shift of a laser beam source can be detected.

Title: Four line-four line sneaking suppressing circuit
Inventor: TOJO TOSHIRO
IPC: H04B3/20
Filed: 1988-09-19
Abstract: PURPOSE:To surely suppress four line-four line sneaking by fetching an input signal and an output signal from a point where their phase difference approaches zero as far as possible, and adding it by means of the input stage of an amplifier. CONSTITUTION:When the voltage extracting point of a resistance R3 is shifted to a point D on the rear stage of the serial circuit of a capacitor C1 and a resistance R1, as a result, the phase difference between the input signal and output signal becomes extremely smaller compared with an ordinary case. Since the phase between the waveforms of the point D and a point B is inverted, and their phases are aligned, only by regulating the amplitudes of the waveforms between the points D and B, their addition waveform becomes zero indicated as the waveform of a point C. Thus, the four line-four line sneaking can be sorely prevented.

Title: Digital filter and digital signal processing system
Inventor: SAKIYAMA SHIRO
IPC: G06F17/10
Filed: 1991-09-13
Abstract: PURPOSE:To provide the digital filter with less number of components by adopting pipeline structure and multi-stage cascade connection between units in a direct type digital filter in which the building block unit is formed for each of several taps so as to solve a pipeline processing adaptability problems. CONSTITUTION:The direct digital filter whose building block unit consists of 8 taps comprising filters 5-1-5-8 is provided with pipeline registers 10, 11. Moreover, an output of a 10-input adder 8 is not the result of sum of 8 data but an output of the result on the way of arithmetic operation. Furthermore, the filter is provided with a data delay device 12 for phase matching to allow multi-stage cascade connection of the filters 5-1-5-8. As a result, the pipeline registers 10, 11 relax the gate delay stage number required for addition of the result of multiplication of all taps. Furthermore, since outputs of the adder 8 are two outputs on the way of arithmetic operation result, a carry propagation delay is eliminated. Moreover, the multi-stage cascade connection of the filters 5<-1>-5-8 is available, then the 8-tap digital filters are connected in cascade. As a result, the digital filter with less number of components is realized.

Abstract: PURPOSE:To prevent leaked high pressure fuel from flowing into a fuel charging port by forming a leakage fuel trapping chamber to trap the leakage fuel, around a plunger between a fuel supply port to be opened into a fuel pressurizing chamber and the fuel charging port being interconnected to a variable displacement chamber. CONSTITUTION:When an electric charge is impressed on a piezoelectric element 77, thereby extending it, a piston 73 goes down whereby a fuel pressure in a variable displacement chamber 78 and a pressure control chamber goes up. Next, when an overflow valve 31 is opened, the fuel pressure in a fuel pressurizing chamber 15 goes up by down motion of a plunger 12, and when the fuel pressure exceeds the specified pressure, a needle valve 7 is opened so that fuel is sprayed out of a nozzle hole 3. In this case, for the purpose that a part of high pressure fuel in the fuel pressurizing chamber 15 collects the high pressure fuel leaked through the clearance between the plunger 12 and a plunger hole 11, there is formed with a circumferential groove 90 over the whole circumference on the outer circumferential surface of the plunger 12. Then, the leakage fuel is made so as to be discharged into a duel supply port 20 via both fuel supply ports 96, 97 after passing through the circumferential groove 90.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To increase the range of materials to be used for an optical recording medium and to provide an optical recording medium showing proper recording conditions and high SN and high stability with large changes in absorption characteristics for light. SOLUTION: This optical recording medium has an optical recording layer 3 dispersing fine particles 32 of a recording material in a mother material 31. The recording material consists of a substance showing metal-insulator transition by stress. Recording is executed by raising the temp. of the layer by irradiation of light and then rapidly cooling to develop residual stress which induces transition of the fine particles of the recording material into a metal. Reproducing is performed by detecting changes in the plasma resonance absorption accompanying changes in the electron state of the fine particles of the recording material. Erasing is done by raising the temp. of the layer by irradiation of light and then slowly cooling decrease the residual stress and to induce transition of the fine particles of the recording material into an insulator.

Abstract: PURPOSE:To prevent the breakage of a cylindrical work surely, by a method wherein molten synthetic resin is injected into the work to fill the inside of the same, thereafter, the outside of the work is filled with the resin through a gate. CONSTITUTION:A mold 12, receiving a thin cylindrical work 10 such as a motor core or the like to effect injection molding, is constituted of a top force 14 and a bottom force 16. A molding chamber 18, having an inner diameter slightly larger than the outer diameter of the work 10 and a depth substantially equal to the height of the work 10, is formed in the bottom force 16. Molten synthetic resin P is injected into the inside space 24 of the work 10 through a first gate 22. In this case, the inside of the work 10 is communicated with the outside of the same through a second gate 26, therefore, a pressure in the inside space 24 is not increased so much even when the synthetic resin P is injected with a high injection pressure through the first gate 22 and the work 10 will never be broken by an internal pressure. After the inside space 24 is filled with the synthetic resin P, the synthetic resin P flows to the outside space 20 of the work 10 through the second gate 26, then, the injection molding is finished.

IPC: F25D17/08
Filed: 1987-09-18
Abstract: PURPOSE: To prevent malfunction of a plate due to freezing of condensate by providing the plate with a radial rib and making a recess in a part of the rib. CONSTITUTION: A rib 17 is provided on the surface of a plate 21 in order to prevent warping thereof at the time of molding and a recess 18 is made in the recess 17 in order to accelerate condensate flow. Inner pressure of a temperature sensitive tube 10 encapsulating a gas is varied by temperature variation and a bellows 3 contracts when the temperature drops below a point for displacing the bellows 3. Consequently, a load lever 4 abutting against the bellows 3 is turned to close a chill outlet 1' with the plate 21. When the temperature rises, the bellows 3 elongates to turn the load lever 4 and the plate 21 begins to open the chill outlet 1'. When condensate adheres to the surface of the plate 21, water drops flows down along the rib 17 and flows out through the recess 18.  Since water does not stand on the surface of the plate 21, malfunction of a damper opening/closing unit can be eliminated.
