Title: Protecting material for underground continuous wall construction method
Inventor: ENOKIDA TADAHIRO
IPC: E02D5/20
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To surely prevent entering of backfilling crushed stone. SOLUTION: A protecting material comprises a protecting plate 22 and a protecting pipe 24, and the protecting plate comprises a base part 22a, a curved thin plate 22b, and a flat plate 22c. The curved thin plate 22b is formed by a flexible metallic thin plate, and is installed in such manner that it holds an outer periphery of a hollow cylindrical part 1d of the first member. The protecting pipe 24 is inserted into the hollow cylindrical part 1b. An inner surface side of the curved thin plate 22b of the protecting plate, is closely brought into contact with an edge of an opening 1c of each hollow cylindrical part 1d, by the charged side pressure of the backfilling crushed stone, when the backfilling crushed stone is charged after the protecting material is installed.  On the other hand, when the thin plate 22b is about to deform when it receives the side pressure of the backfilling crushed stone, the side where the flat plate 22c is installed, is moved forward because the end of the curved thin plate 22b is fixed to the base part 22a, and is pressed to the edge of the opening 1c. The curved thin plate 22c is thus moved, so that the flat plate 22c is pressed to the fitting plate 14.

IPC: G06F13/14
Filed: 1990-02-20
Abstract: PURPOSE:To improve the working efficiency of a CPU by starting up a system with the CPU and applying interruption on the CPU after the lapse of prescribed time. CONSTITUTION:The access of the CPU 3 to the common resource of a memory 5 is performed by checking a control bit for contention prevention attached on every common resource and setting the control bit when the control bit is omitted, and setting the address of the control bit on a collation circuit 2 and setting the maximum time when the control bit is set normally on a timer 4 when the control bit is set. When interruption is applied from the collation circuit 2 by making access the control bit by another control part 6, the CPU 3 checks the control bit by the interruption. Also, when the timer 4 times out as applying no interruption from the collation circuit 2, the interruption from the timer 4 is generated, and the existence of abnormality in the CPU 3 of another control part 6 in which the control bit is omitted can be found out. In such a way, it is possible to reduce a load on the control part, and to reduce the occupancy ratio of a bus.

Title: Rotor balancing system
Inventor: MATSUSHITA OSAMI
IPC: G01M1/38
Filed: 1978-04-07
Abstract: PURPOSE: To make it possible to correct rotor balance without information on the amount of laser cut by using the phase of the rotor vibration vector and the phase of the effect vector due to the laser irradiation at minute intervals.  
     CONSTITUTION: The shaft vibration of rotor 16 is measured by vibration detector 3, and its amplitude a and phase ϕ are obtained. On the other hand, laser processing device 5, which laser-cuts the imbalance of rotor 16, operates in accordance with the ON-OFF signals of switch 17, which indicate whether the laser is to be irradiated or not. When the vibration amplitude becomes large and reaches the operational tolerance above the amplitude tolerance, switch 17 becomes ON, and laser processing device 5 starts laser irradiation. During the laser irradiation, amplitude a and phase ϕ of rotor 16 and laser irradiation phase θ are given to arithmetic circuit 18 and then they are returned to laser processing device 5.

Title: Contact switch device
Inventor: KANEMOTO NAOKI
IPC: H01H3/60
Filed: 1995-02-28
Abstract: PURPOSE: To prevent characteristics deterioration of opening/closing performances of contacts by providing a buffer member which deforms so as to buffer impact generated when a movable contact abuts on a fixed contact and deforms to its original shape, when the movable contact separates from the fixed contact, on a fixed contact plate. CONSTITUTION: A damper (buffer member) 6 comprises a base board 61, sheets 62, 63, and fluid. When a coil provided on an electromagnet device 10 is energized, a drive member 5 rotationally moves in such a state as supported on a rotational support part 51 and when the drive part 53a drives a movable contact plate 4, the movable contact 3 abuts on a fixed point 1. Next, the fixed contact plate 2 is displaced in such a way as applying pushing pressure on the sheet 62 of a damper 6 by impact of abutment so that the damper 6 in a state of abutting on the first chamber 62 is deformed.  This deformation can absorb impact generated by bounce of the contact 3 in closing the contact and vibration after opening the contact so as to prevent characteristics deterioration of the contact opening/closing performances, and the damper is applied pressure by a presser part 52 of the member 5 in such a state as returningly deforming to its original shape. Necessity of separate installation of a presser member can be thus eliminated and the number of the part items can be reduced.

Title: Intermediate frequency amplifier provided with squelch detecting circuit
Inventor: SAIKAI TOSHIO
IPC: H04B1/10
Filed: 1982-03-16
Abstract: PURPOSE:To set the starting point of a squelch function at an optional input signal  level, by supplying the added voltage of AGC voltage corresponding to an input signal  level and output voltage of a detector, to a squelch control part. CONSTITUTION:A signal inputted from an input terminal 1 is amplified by amplifiers  2-4, is converted to a DC signal by a detector 7, and after that, is inputted to an  AGC voltage amplifier 8. The AGC voltage amplifier 8 controls the gain by applying  AGC voltage for making an output signal level of a terminal 6 constant, to the amplifiers 2-4, against a vairation of an input signal level of the terminal 1. Within the  range where AGC is operated, the AGC voltage is varied in accordance with the input  signal level. Also, when the input signal level drops and the amplifier attains the  maximum gain, the AGC voltage becomes constant, and output voltage of the detector is varied in accordance with the input signal level. Voltage which adds the AGC voltage and the output voltage of the detector by an adding circuit 10 is varied correspondingly even for the low input signal level to which AGC is difficult to operate. A squelch function starting point can be set optionally by generating a squelch control signal by  this added voltage.

Title: Production of deformed section bar
Inventor: ABE HAJIME
IPC: B21B1/08
Filed: 1982-03-17
Abstract: PURPOSE:To produce deformed section bars having no twists by rolling blank materials with grooved rolls so as to roll down the parts to be thin-walled but not to roll down the parts to be thick-walled. CONSTITUTION:A bar 1 having a flat plate-like section molding which is a blank material is moved longitudinally between a grooved rolls 3 having a groove 2 provided on at least one surface side thereof and a roll 4 provided on the opposite side. While the thin-walled part 5 to be thin-walled in the transverse direction of the bar 1 is rolled down between a projecting surface part 6 of the roll 3 which delineates the part 2 and the roll 4, the bar receives no rolling down effect in the thick-walled part 7 to be thick-walled in the transverse direction located in the position corresponding to the groove 2. Thus, the flow by the deformation of the part 5 moves to the part 7 which is not applied with the rolling down force, that is, into the part 2, thereby packing the part 2. The generation of the difference in the longitudinal or rolling direction occuring in the difference in the wall thickness in the transverse direction is thus prevented, and the generation of twists after the rolling is eliminated.

Abstract: PURPOSE:To firmly hold a heat transfer tube bundle, that includes many kinds of U-bent tubes different in bend radius, by steady plates which are inserted in gaps between bending planes, by a method wherein the outside diameter of the bends in the direction perpendicular to the bending planes are restricted to a specified scatter. CONSTITUTION:Bends of many kinds of U-bend pipes 11-1n different in bend radius are arranged at equal intervals in the direction Z perpendicular to the bending planes and in the direction R of bend radius. A steady plate 2 is inserted in the gap between the bending planes from the outer circumference side toward the inner circumference side. In this case, at the location where the steady plate 2 is inserted, the outside diameters Dn to Dn+1 of the bends in the direction perpendicular to the bending planes are restricted to a specified scatter of less than 0.1mm, regardless of bend radius. Therefore, all gaps Gn to Gn+1 between the bends are restricted to a specified scatter of less than 0.1mm.
