Title: Semiconductor laser
Inventor: TOMITA KEISAKU
IPC: H04B10/07
Filed: 1993-06-15
Abstract: PURPOSE:To suppress drift of a semiconductor laser significantly by detecting the optical output and the oscillation wavelength of the semiconductor laser and then controlling the optical output and the oscillation wavelength with reference to the optical output and the oscillation wavelength thus detected. CONSTITUTION:An optical output stabilizing circuit 2 detects the drift of a semiconductor laser 11 based on the comparison between a reference voltage, variable depending on the fluctuation in the mark rate of a modulation current being applied directly to the semiconductor laser 11, and an output from a light receiving element 12 for monitoring the optical output. The drift is then amplified and employed in the control of bias current of the semiconductor laser. On the other hand, an oscillation wavelength control section 3 detects, at the comparing circuit 113 thereof, the fluctuation in the oscillation wavelength of the semiconductor laser 11 which is then subjected to differential amplification at a differential amplification circuit 114. A power supply 17 regulates power supply to a temperature regulation element 16 in the laser thus regulating the temperature of the laser and controlling the fluctuation in the oscillation wavelength.

Filed: 1986-06-18
Abstract: PURPOSE:To prevent the leakage current from flowing between the second interconnection layer and a semiconductor substrate by a method wherein an impurity region is extended to a part below a part to form the first interconnection layer. CONSTITUTION:A leakage preventive diffused layer 4 is provided to substantially extend a diffused layer 7 to the part below the first interconnection layer 5. Resultantly, a PN junction between the diffused layer 7 and a semiconductor substrate 1 exposed to a part near an exposed part 6 of diffused layer 7 in contact with the second interconnection layer 10 can be exposed to a part distant from the second interconnection layer 10. Through these procedures, the leakage current flowing between the second interconnection layer 10 and a semiconductor substrate 1 can be minimized.

Title: Act stand-by switching circuit
Inventor: YOSHIMURA SHUJI
IPC: G05B7/02
Filed: 1987-06-10
Abstract: PURPOSE:To prevent the switching due to an erroneous action by providing a switching circuit to switch an active device to stand-by and a stand-by device to an active when a switching signal is added by a switching prohibiting control circuit. CONSTITUTION:To a switching prohibiting control circuit 1, a signal WT to show that a stand-by device executes the normal operation and a signal S to make the stand-by device active are added. When two signals are simultaneously added to the circuit 1, the circuit 1 outputs the switching signal to a switching circuit 2. By adding the switching signal, the active device comes to be the stand-by and the stand-by device comes to the active. Since the power source turn-off and a program run-away do not occur when the stand-by device executes the normal action, the condition of the active and the stand-by can be switched only at the normal time and the switching due to the erroneous action can be prevented.

Title: Method of producing anchor enclosing sand
Inventor: NAKAMURA SOUJIROU
IPC: A01K75/06
Filed: 1982-08-20
Abstract: PURPOSE:To produce economically and rapidly and anchor by collecting sand in a bag with a pump for transporting water. CONSTITUTION:A pump 1 is connected to a collecting hose 2 and a discharging hose 3 for running. When an end 4 of this hose 2 approaches sand layer in water, the sand in the neighborhood is sucked together with water in the direction of arrow so that sand grain 5 is carried by water flow and pushed out of a discharge port 6 through the pump 1. When a cloth bag 7 is then mounted on the discharge port, the sand is caugth in the bag and water flows outside the bag through the cloth so that the bag is filled with the sand by pump pressure. Thus, the bag 1 filled with the sand is closed and bound with a steel wire on the opening, providing immediately a weight which can be used for an anchor.

Title: Method for charging molten pig iron into converter
Inventor: HASEGAWA TERUYUKI
IPC: C21C5/46
Filed: 1985-06-29
Abstract: PURPOSE:To enhance the yield of steel and the rate of recovery of gas by directly charging molten pig iron into a converter and measuring the weight of the molten pig iron in the converter so as to reduce a drop in the temp. of the molten pig iron. CONSTITUTION:The weight of molten pig iron charged into a converter is measured by a measuring means such as a load cell set in the converter. The measured value is inputted in a computer controlling blowing in the converter as one of control data. Since molten pig iron in a molten pig iron conveying pan is directly charged into the converter, the molten pig iron is required to be poured only a time and a drop in the temp. of the molten pig iron can be reduced. As a result, the overall yield of tapped steel and the rate of recovery of gas in the converter are enhanced. A charging pan is made unnecessary and the consumption of refractories can be avoided.

IPC: F16K17/10
Filed: 1993-06-15
Abstract: PURPOSE:To prevent generation of noises which may be caused by fluid flowing the throttled passage without providing a special shape of valve body. CONSTITUTION:A throttle flow passage 15 is formed on a meter out poppet (valve body) 13 in the vicinity of a seat 12 of a valve body 11, for the outflow of fluid from the side of an outer peripheral surface 16a while throttling inward. A wall 19 against which the fluid flowing out from the throttle flow passage 15 is struck is provided. An enlarged flow passage 21 whose sectional area is larger than that of the flow passage 15 is formed. The fluid is throttled, flowed out into the meter out poppet 13, and then immediately struck against the wall 19. The fluid is then flowed through the enlarged flow passage 21 whose sectional area is enlarged. It is thus possible to reduce the velocity of the fluid to the extent that no cavitation is generated without providing the special shape of valve body 11, and prevent generation of noises.

Title: Barrel for writing instrument
Inventor: KITATSUME TAKAHIRO
IPC: B43K29/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent releasing of a sealing member laminated on an outer periphery of a barrel made of a resin material and to easily confirm a character or the like, by forming a recess display on the periphery of the barrel and forming a protrusion character on the display so that the end face does not exceed an extension line of the outer periphery of the barrel. SOLUTION: On a barrel 1 of the writing instrument, a grip member 4 is, for example, dichroically formed at a grip portion 3 of a barrel body 2, and a slip-proofing groove 5 is formed in a ring state on a surface of the member 4. In this case, a recess display 6 extended in an axially central direction is formed on the outer periphery of the body 2, and a protrusion character 7 is formed of a maker's name or the like on the display 6. The character 7 is formed so that the end face does not exceed an extension line of the outer periphery of the body 2. Further, a sealing member 8 is laminated on the outer periphery of the body 2 including the display 6.

Title: Precision casting method and precision casting device
Inventor: OKAMOTO SHIROU
IPC: B22D23/00
Filed: 1978-11-22
Abstract: PURPOSE: To set pouring timing and pouring speed as desired by providing a molten meterial blow hole to the bottom wall of a crucible and selecting the timing of applying gas pressing or pulling force of molten material blow and the magnitude of the pressure.  
     CONSTITUTION: When the material 33 in a melting furnace 1 is melted and reaches an adequate temperature, arc discharge is stopped and the inside of the melting chamber 1 is boosted. This pressure causes the molten material 33 to be blown through a molten material blow hole 17 and be poured into the molding cavity 23 through a sprue 22. At this time, the molten material 33 is pressed under the pressure lower than the inside of the melting chamber 1 from the sprue 22 side and while its boiling is being suppressed, it is blown out at a correct speed and flows smoothly deep into the molding cavity 23, thus it correctly solidifies from the innermost end side toward the sprue 22. If the pouring temperature and pouring speed are maintained in a correct range by arbitrarily selecting the timing of applying these differential pressures and the magnitude of the differential pressures, the material is cast precisely to the correct shape even in the thin and broad portions of the product.
