Title: System switching controller for optical transmission line
Inventor: IMURA KAZUHISA
IPC: H04B10/29
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To select a correct optical transmission line at all times even when a switching control section is inserted or withdrawn. SOLUTION: In the case of selecting a standby system of optical transmission lines, a switching control signal 100 outputted by a switching control circuit 141 is at a low level and a reset signal of a power reset circuit 142 is at a high level, then switching control signals 101, 102 outputted from NAND gates 143, 144 are respectively at a high level and a low level. Thus, a set terminal S of a latch circuit 114 goes to a high level and a reset terminal R reaches a low level and its output signal 103 goes to a low level.  In this state, when the switching control circuit 14 is withdrawn, the switching control signals 101, 102 given to the latch circuit 141 both go to a high level and the set terminal S and the reset terminal R go to a high level, but since the latch circuit 114 adopts a negative logic input, the output signal 103 remains a low level and then the selection of the standby system for the optical transmission lines is maintained.

Filed: 1994-02-14
Abstract: PURPOSE: To prevent intermodulation due to a stray signal by constituting gain controllers which are provided on the input sides of first and second amplification systems and are based on mismatching of input impedance so that they have no influence upon an input coupling circuit in the preceding stage. CONSTITUTION: Terminals P1 and P3 of input and output coupling circuits CI and CO are used as an input terminal I and an output terminal O of a high frequency signal, and terminals P4 and P2 are grounded through load resistances RI and RO. Outputs of terminals P2 and P3 of the circuit CI are inputted to terminals P1 and P4 of the circuit CO through variable impedances (Z) 1 and 2 and amplification systems Al and B and are outputted from the terminal O. Impedances Z1 and Z2 comprise PIN diode groups and are controlled by an input Sk to allow mismatching of input impedance between systems A1 and B but have no influence of the impedance in the circuit CI of the preceding stage. Thus, intermodulation due to a stray signal is attenuated.

Title: Protecting circuit for phototrigger thyristor
Inventor: YUJI YOSHITAKA
IPC: H03K17/08
Filed: 1980-02-14
Abstract: PURPOSE:To prevent breakover from being brought about depending on the rising ratio of an off-state voltage without lowering phototrigger sensitivity by a method wherein a transistor is connected between the gate and cathode of a phototrigger thyristor. CONSTITUTION:A phototrigger thyristor 1 is triggered by a light emission diode 2 and turned on when a forward voltage has been applied across the anode and cathode of the phototrigger thyristor 1. Since a transistor 4 is in an off state at this time, high impedance exists between the gate and cathode of the phototrigger thyristor, so that phototrigger sensitivity is maintained to be high. When an off-state voltage with a sharp rising ratio is applied between the anode and cathode of the phototrigger thyristor 1, the transistor 4 is turned on, while low impedance is provided between the gate and cathode. Therefore, the increased critical rate of rise of  the off-state voltage prevents breakover from being brought about against a sharp  threshold voltage.

Title: Integration circuit
Inventor: YAMASHITA NORIYUKI
IPC: H02P27/02
Filed: 1986-01-29
Abstract: PURPOSE:To extend the apparent time constant by allowing the titled integration circuit to generate a step wave when a sawtooth wave reaches a setting value, restoring the sawtooth wave to the initial value and adding the step wave and the sawtooth wave. CONSTITUTION:When an input Vin reaches an H level, the charging of a capacitor 26 is started and a voltage Vc rises. In bringing an output Q of an RS'-FF23 to '0' level, a switch 24 is thrown to the position (a) and an adder 25 output a difference Vsw between a voltage Vc and a reference voltage source 28 as it is. When the output Vsw reaches a potential V1 of the power supply 32, the output Q of the RS-FF23 goes to 'H' to invert the output of a multiplier 11, then the capacitor 26 is discharged, the switch 24 is thrown to the position (b) and the inverted output of the differential amplifier 27 is fed to the adder 25. As a result, the adder 25 adds the output Q of the RS-FF23 and the inverted output of the difference between the potential Vc and the potential of the power supply 28 thereby outputting a further increased output voltage Vout.

Title: Hoisting machine for elevator
Inventor: TAKAHASHI TATSUHIKO
IPC: F16D55/00
Filed: 1989-01-30
Abstract: PURPOSE:To prevent the magnetization of a gear shaft and a gear and prevent the generation of the abnormal noise and vibration at the meshing part of the gear and the breakage of the gear by making the gear shaft diameter opposed to the through hole parts of an electromagnet and a movable plate, thinner than the root part and installing a cylindrical pipe made of nonmagnetic material onto the outside diameter part. CONSTITUTION:When a dc electromagnet 7 is energized, a magnetic flux is generated in a magnetic circuit formed from the electromagnet 7 and a movable plate 5, and said movable plate 5 is attracted towards the electromagnet 7. In this case, the leak magnetic flux 8 which is generated in the through holes 7' and 5' of the dc electromagnet 7 and the movable plate 5 flows at the separated positions on the surface side of a nonmagnetic body part 20, and does not reach a gear shaft edge small diameter part 13a. This comes from the utilization of the principle that the magnetic force attenuates in proportion to the square of the distance, and a gear shaft 13 is not affected by the magnetic influence and not be magnetized. In this case, the rigidity of the small diameter part 13a is increased by the small magnetic body part 20 which is installed onto the outside diameter part of the small diameter part 13a.

Title: Method for grinding pigment to power
Inventor: HAYASHI YOSHIAKI
IPC: B02C17/00
Filed: 1993-02-04
Abstract: PURPOSE:To obtain an efficient grinding method as a means to improve the clarity of color and dispersancy by using a ground medium with a specified Young modulus of the surface when grinding inorganic pigment powder (excluding iron oxide pigment powder) in a container in which the ground medium is provided internally. CONSTITUTION:When grinding inorganic pigment to powder (excluding iron oxide pigment) in a container in which the ground medium is installed internally, a ground medium used has 0.001 to 10GP a of Young modulus of the surface part. If the Young modulus of the surface of the ground medium is not more than 0.001GPa, it is not adequate as the grinding effect deteriorates on account of a low impact force. On the other hand, if the Young modulus exceeds 10GPa, coarse coagulated particles generate due to excess grinding according to this grinding method, generation of coarse coagulated particles can be prevented, thus improving dispersancy. Consequently, it is possible to improve the coloring capability of pigment and the clarity of color efficiently to a significant extent.

Title: Exhaust manifold of internal combustion engine
Inventor: WATANABE YOSHIMASA
IPC: F01N13/10
Filed: 1995-02-06
Abstract: PURPOSE: To provide an exhaust manifold having an outer circumferential wall section where a tensile stress is generated at least when the engine is in operation, wherein the outer circumferential wall is precluded from crack generation despite eventual generation of tensile stress by furnishing a compressive stress applying means which gives compressive stress to the wall periodically. CONSTITUTION: When engine operation is started, the temp. of an exhaust manifold 1 heightens, but the temps. of bosses 6, 8, 10 rise slowly compared with the temp. of the manifold 1, and the temps. of bridging members 11, 12 rise still more slowly. Accordingly the temps. of the bridging members 11, 12 remain less high even though the temp. of the manifold 1 heightens, and the amount of thermal expansion becomes smaller than that of the manifold 1. This causes generation of a compressive stress in the manifold 1 to result in a rise of the temps. of the bridging members 11, 12, so that a tensile stress is again generated in the exhaust manifold 1. Thus micro-cracks generated when tensile stress is applied are corrected by this compressive stress, and the outer circumferential wall of the manifold 1 is precluded from crack initiation.

Filed: 1989-01-27
Abstract: PURPOSE:To load information media having different shapes and thickness into the same reader by setting a cover which covers a connection pin on a support stage and has a through hole where the tip part of the connection pin passes at a recessed or projecting part of an information medium set opposite to the cover. CONSTITUTION:At an initial stage, a connection pin 24 is protected by a cover 15. When an information medium 1 is loaded, the cover 15 is coupled with a recessed or projecting part of the medium 1. Then the connection terminals T1-T5 and the pin 24 are positioned opposite to each other. When the cover 15 is depressed by the medium 1, the tip part of the pin 24 is exposed through a through hole 16 and touches the terminals T1-T5. When the cover 15 is retracted, the tip part of the pin 24 is exposed over the cover 15. Thus the pin 24 is connected to the terminals T1-T5 with the constant pressure. Both the tip part of the pin 24 and the cover 15 are held elastically and therefore set back to their original positions when the medium 1 is removed. Thus a connection unit 22 is satisfactorily connected to the medium 1 regardless of different shapes and thickness of the media 1.

Title: Fiber reinforcing resin alternate material for reinforcing bar and its manufacture
Inventor: KITSUTA TOSHIYUKI
IPC: B29K105/10
Filed: 1989-01-27
Abstract: PURPOSE:To improve the strength of reinforcement by forming a sectional outside shape out of straight lines and curved lines and manufacturing a fiber reinforcing resin alternate material for reinforcing bar of closed shape where a straight portion is faced outwards or spiral shape out of winding form using a mandrel. CONSTITUTION:A winding groove 5 consisting of a straight portion 7 and a curved portion 8 is formed at a split mandrel 4. A resin impregnated fiber bundle is wound around the groove 5, and after heating and hardening, it is removed from the mandrel 4 to install a fiber reinforcing resin alternate material for reinforcing bar. A alkali resisting protective layer and as necessary a adhesion reinforced layer to concrete are installed on a surface. At this time, the outside of the wound fiber bundle becomes flat of itself. When the groove 5 is taken at regular intervals, on the other hand, it becomes a closed reinforcement 1 and when provided continuously, it becomes a spiral reinforcement. It is thus possible to make the peripheral length larger than a circular section to increase the adhesive power to concrete, preventing the decrease in the strength of a bent portion.
