Title: Method and apparatus for manufacture curved tube
Inventor: SAITOU IWAO
IPC: B21D7/06
Filed: 1978-04-30
Abstract: PURPOSE: The simply constructed apparatus which can efficiently manufacture the highly accurate product and needs no high exactness in forming the tunnel, by turning the curved core metal together with the internal die and the formed curved tube against the external die, and by further turning the curved core metal against the curved tube to part from the curved tube.  
     CONSTITUTION: The curved tunnel 7 is formed by the stationary external die and the freely rotatable internal die, in which the semicircular grooves 3, 6, are provided correspondingly to the tube blank (a) respectively along the concave and convex planes 2, 5, of required curvature. The curved core metal 8, being sustained by the member 11, and facing to the insertion port 9 by the tip of core metal 8, is inserted into the axial center of above curved tunnel 7, so as to form a curved clearance. The tube blank (a), within the guide die 13 whose insertion hole 14 is communicated to the curved clearance 12, is press formed by the press rod 15. Next, by turning the core metal 8 together with the internal die 4, the curved tube a' also turns accompanying them and is stopped by the stopper 16; then, the rod 15 is retreated and the die 13 returns to the initial position. The core metal 8 is not stopped because of the notched groove 17, and is further turned independently or together with the internal die 4, and is pulled away from the curved tube a', and is reversely turned to return to the initial position after removing the curved tube a'.

Title: Infrared sensor
Inventor: FUTAKI TOSHIRO
IPC: H01L31/10
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To eliminate dependence of infrared rays on the irradiating direction due to selection rules by detecting a photocurrent generated through excitation of electrons or holes in a quantum dot upon irradiating a laminate with infrared rays thereby detecting the infrared rays. SOLUTION: A barrier layer 14 is doped with impurities for forming a shallow level and thermally excited electrons are sunken to a quantum dot. When a voltage is applied across a laminate of the barrier layer 14 and a quantum dot layer 16, a potential gradient corresponding to the applied voltage is generated and the band is inclined. When the laminate is irradiated with infrared rays, the electron occupying the basic level is excited through absorption of infrared rays by the quantum dot. When the electron exceeds the potential barrier to produce a free carrier, the free carrier contributes to electric conduction to generate a photocurrent which is then detected. Since the quantum dot can also absorb infrared rays incident normally to the infrared sensor, dependence of infrared rays on the irradiating direction of infrared rays due to selection rules thereof can be eliminated.

Filed: 1978-04-28
Abstract: PURPOSE:To obtain a high integration after maintaining a high-speed operation by constituting the input-side high-speed operation circuit by high-speed logical gates and constituting the divided low frequency circuit by I<2>L logical gates. CONSTITUTION:Pre-scaler circuit 1 which is constituted by high-speed logical gates such as ECL performs the frequency division of input signal fin by factor P or P+ or -1. After divided by auxiliary frequency divider 2, the output is subjected to frequency division by factor M in variable frequency divider 3 by external data M. Meanwhile, the frequency division output of circuit 1 is inputted to auxiliary variable frequency divider 4 and is subjected to frequency division by factor q by external data q. Then, frequency dividers 2 and 3 are constituted by I<2>L, and circuit 4 is constituted by ECL, etc. Latch circuit 5 which was integrated simultaneously with these circuits is set by the output of frequency divider 3 and is reset by the output of frequency divider 4 and issues a reset signal and a control signal to frequency divider 4 and circuit 1 respectively. Therefore, in respect to fin, P frequency division operation is repeated MN-q times after P 1 frequency division operation is repeated q times. As a result, the total number of frequency divisions for fin becomes PN M+ or -q, and variable set is possible by data M and q.

Title: Ceramic composition for sensing gas
Inventor: KOMINE YOSHIHARU
IPC: C01G33/00
Filed: 1982-03-30
Abstract: PURPOSE:To detect alcohol selectively with high sensitivity, by using a composite oxide of titanium and niobium as an essential component of a ceramic compsn. for sensing gas. CONSTITUTION:A composite oxide contg. titanium and niobium in a 0.5<=Nb/ Ti<=4 range is used as an essential component of a ceramic compsn. for sensing gas. Since the electric resistance value of such material changes largely in accordance with 0-3,000ppm conc. of gaseous alcohol, the gaseous alcohol is detected easily by measuring the electric resistance value. The material is hardly sensible with combustible gases such as methane, ethane, propane, H2 and CO except alcohol; therefore; it has much better selectivity as compared to conventional alcohol sensors. More particularly, the material consisting of the composite oxide ranging 0.5<=Nb/Ti<=4 has extremely remarkable sensitivity.

Abstract: PURPOSE:To suppress and compensate a DC drift effectively by varying the distribution of an electric field, applied to and nearby an optical waveguide by a couple of a signal and a grounding driving electrode, greatly by the variation of the frequency of an electric signal. CONSTITUTION:The optical waveguide 2 is formed on the surface of an electrooptic crystal substrate 1 and the couple of driving electrodes 5 and 6 for a signal and for driving are formed on the optical waveguide 2.

Title: Power steering device
Inventor: MOMIYAMA FUJIO
IPC: B62D6/02
Filed: 1990-03-02
Abstract: PURPOSE:To balance a steering force exerted and a reaction force to each other so as to enhance the steering property of a power steering device by providing each compensating valve with a V-shaped channel which when the valve is actuated restricts hydraulic oil to be given to a hydraulic auxiliary booster and supplies the oil to a reaction hydraulic pressure means. CONSTITUTION:Right and left compensating valves 22a, 22b are provided with respective V-shaped channels each of which when actuation of each valve is started restricts hydraulic oil to be given to a hydraulic auxiliary booster 5 and supplies the oil to a reaction hydraulic pressure means 21. A program controlling circuit 7 receives a detection signal from a steering force sensor 3 and the compensating valves 22a, 22b are actuated by solenoid valves 6a, 6b and then pressure oil from a hydraulic pressure generating means 4 is supplied to a piston inside the compensating valves 22a, 22b. As the pressure oil is forced to pass through each V-shaped channel oriented in the axial direction of the outer periphery of the piston, the oil is restricted and discharged to a supply passage leading to the reaction hydraulic pressure means 21. During the process supply pressure is reduced so that sudden large pressure is avoided. Exertion of a sudden reaction force simultaneous with handling of a steering wheel 1 is thus prevented so as to enhance the steering property of a power steering device.
