Title: Production of composite ejector pin
Inventor: SHIGEMOTO NOBUMASA
IPC: B23K20/12
Filed: 1979-03-26
Abstract: PURPOSE: To inexpensively produce the homogenous product of high dimensional accuracy by bonding the head part and stem part having undergone finishing separately by a friction pressure-welding method.  
     CONSTITUTION: A head part a is formed by steel blank having been annealed and a stem part b is formed by the steel blank having undergone the heat treatment of the nature similar to or dissimilar from this. The stem part is subjected to surface hardening, bending straightening, polishing, etc. to secure abrasion resistance and dimensional accuracy, after which it is bonded to the head part by a friction pressure-welding method. Thence, if the head part is polished and the size is adjusted, the composite ejector pin of homogeneous quality and high strength becomes inexpensively volume-producible.

Title: Air fuel ratio control device in combustion furnace
Inventor: TAMURA MASATOSHI
IPC: F23N3/08
Filed: 1981-03-13
Abstract: PURPOSE:To enable a control over O2 without modifying a link work by using a control device for variably controlling the blower speed, means for sensing a concentration of a specified constituent in the exhaust gas and an adjuster means for controlling the variable speed control device. CONSTITUTION:When a pressure in the steam pipe 4 is varied, the control motor 12' is operated via automatic combustion control device ACC 10. Fuel valve 15 and air damper 16 are operated through the control motor 12' and the link work 14. Characteristic of flow rate of these valve 15 and the damper 16 are roughly and mechanically adjusted, so that the fuel may be burnt. When a concentration of O2 in the exhaust gas detected by the O2 sensor 19 to a rate of excessive air in the fuel can be estimated, so the O2 controller 20 acts on the variable speed control device VVVF21 so as to make a function value of a signal from the load sensor 12' having a control motor built therein to serve as a set value and to make a desired value of O2, and the value of O2 is thus controlled.

Title: Optical waveguide element
Inventor: SATO AKIRA
IPC: G02B6/122
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the resonance of vibration and to obviate the occurrence of the sensitivity change of electric field intensity by a frequency change by forming an optical waveguide forming surface and its opposite surface so as to have an angle above a specific value with the optical axis as the axis of rotation. SOLUTION: An optical waveguide 3 and an electrode 3 are formed on the X surface A of an X-cut lithium niobate substrate 1. The counter surface B of the X surface A is so polished as to have >=35 angle θ of inclination around the optical axis as the axis of rotation with respect to the X surface A. When an AC electric field is impressed on such optical waveguide element, vibration is generated by the displacement of the substrate 1 between the electrodes and propagates as transverse waves in the thickness direction of the substrate. The transverse waves are reflected at 2θ angle with the counter surface B. In the case of ordinarily used 500μm thickness and 10μm electrode width, progressive waves and reflected waves are separated on the A surface A at θ:35' or larger angle and, therefore, both waves do not exert interaction on each other any more.  The resonance state of the progressive waves and the reflected waves at an arbitrary frequency do not arise any more.

Abstract: PURPOSE:To obtain an alloy ingot having uniform composition at each part and excellent workability by dividing a mold into plural pieces in casting direction and each divided mold as movable in the direction for center in the water cooled copper mold with which the ingot is obtd. by solidifying molten metal. CONSTITUTION:The mold is constituted of plural movable water copper mold (a) and each movable water cooled copper mold (a) is made to movable in the direction for center with an operating rod (c). When the solidification starts from lower part of the mold by pouring the molten metal, the movable water cooled copper mold (a) is reduced in the diameter toward the direction for center with the operating rod (c) in the order from the lower part. By this method, the ingot, which is solidified an reduced in the diameter, can be always brought into contact with the mold wall, and the cooling velocity becomes large. By shifting the movable water cooled copper mold (a) to the different direction from the mold at upper side of one step, the ignot can be undirectonally cooled. By this method, as the composition of produced Nb-Ti alloy ingot is uniformized at each part, Nb-Ti superconducting wire having excellent workability can be efficiently obtd.

Abstract: PURPOSE: To obtain a composite pulse generator which is used for the distortion measurement of the full higher harmonic to measure the nonlinearity characteristics of the amplifier or the like.  
     CONSTITUTION: The voltage of DC power source E1 is controlled to constant voltage V 1  via resistance r 1  and variable resistor R 1  to be then applied to gate circuit G1. In the same way, the voltage of DC power source E2 is applied to gate circuit G2 after control to constant voltage -V 2 . In this case, the reference voltage is 0. With control given to circuit G1 by control signal b, rectangular pulse c featuring height V 1  and width T 1  is obtained as the output and by securing the conduction for G1 only for T 1  of fixed cycle T; while rectangular pulse f featuring height -V 2  and width T 2  is obtained as the output by securing the conduction for circuit G2 for only T 2  of cycle T and via the control by control signal e respectively. These rectangular pulses are added together through adder A to obtain composite pulse g. Then both T 1  and T 2  are fixed with the control given to voltages V 1  and V 2  via variable resistances R 1  and R 2  in order to meet the conditions of T 2 =T 1 + (V 1 /V 2 )T 1 , and accordingly the DC component can be made 0 for the composite pulse.

Filed: 1985-02-26
Abstract: PURPOSE:To reduce blow-by loss of fresh air by supplying mixture forcibly sent to a scavenging path from a carbureter through to a crank chamber into a cylinder as scavenging flow separated into mixture having different fuel concentration through the scavenging path and a scavenging hole. CONSTITUTION:Mixture of air prepared by a carbureter and gasoline flows into a crank chamber 3 through an intake pipe 6. Here it receives turbulence and centrifugal force through a balancer 2, a crankshaft, etc. and is urged against the inner wall of the crank chamber 3. Then, fuel liquid drops, grains and the like in fuel flow into a sub-chamber 5 through a thin groove 4. Thus, rich mixture is formed in the sub-chamber 5 and lean mixture in the crank chamber 3. And while scavenging is carried out by the lean mixture, the rich mixture is supplied to a position remote from a scavenging hole to control blow-by of fuel. Thus, the blow-by loss of fresh air is reduced.

Filed: 1991-03-04
Abstract: PURPOSE:To suppress the vibration of a robot arm by installing an angular velocity sensor for detecting the angular velocity of arm in a robot arm, and by comparing the angular velocity with an operating command to control the robot arm. CONSTITUTION:In an arm connected to a rotary means 26 that is driven by a command signal from operating command equipment 23, an angular velocity 21 is installed. A detecting angular signal from angular velocity sensor 21 is discriminated by a frequency discriminator 22. The discriminated signal is compared with a command signal from an operation command apparatus 23 and calculated by a relative computing element 24, thereby outputting a vibration suppressing signal. A servo-amplifier 25 amplifies and converts this signal for driving a rotary device 26. Thus, the suppressing signal drives the rotary means 26 without accumulating a driving torque as elastic energy, thereby being able to suppress the generation of vibration caused by operation of the arm having a flexible structure or the like, and to attenuate the generated vibration.
