IPC: G01L1/22
Filed: 1984-05-31
Abstract: PURPOSE:To reduce the error in the measurement of load using a washer type load cell by a strain gauge system, by calculating load by using a weighted addition formula preliminarily calculated from the longitudinal strain in the inner surface side of an annular block and that in the outer surface side thereof. CONSTITUTION:A load cell is constituted so as to detect the longitudinal strain in the inner surface side of a web having an I-shaped cross-sectional area and that in the outer surface side thereof by adhering strain gauges to a plurality places of the inner and outer surfaces of said web in the circumferential direction. Further, the weighted addition formula of longitudinal strains in the inner and outer surface sides is defined by formula I and the output Fr of the load cell is calculated according to formula II by using the weighted addition value epsilon. The load measuring error e3 in this case is imparted by formula III. By performing heavy regression analysis of inner and outer surface side strains epsilon1, epsilon0 when the loads of two kinds or more of load patterns are applied, coefficients a, b of the formula I are calculated. Herein, F0 is load actually applied to the load cell.

Title: Manufacture of spark plug
Inventor: KAGAWA JUNICHI
IPC: H01T21/02
Filed: 1995-05-08
Abstract: PURPOSE: To arrange a spark consumption resistant electrode material such as noble metal only in a spark gap forming part of a central electrode without causing the thermal degradation. CONSTITUTION: After a central electrode base material 20 to which a noble metal tip 21 is joined is sealed in an insulator 3 by glass, a position of the noble metal tip 21 in a tip side part of the central electrode base material 20 is recognized by discriminating a difference in a degree of oxidizing discoloration between an Ni alloy part of the central electrode base material 20 and the noble metal tip 21 in glass sealing. A central electrode 2 is rotated in the shaft circumferential direction so that a position of the noble metal tip 21 coincides with the direction of an outside electrode 5 beforehand welded to a main body metal fitting 4 on the basis of this recognition, and afterwards, the insulator 3 in which the central electrode 2 is arranged is inserted into and installed in the main body metal fitting 4.  Since a position of the noble metal tip 21 can be recognized by comparing contrasts of oxidizing discoloration of the central electrode base material 20 of the central electrode 2 and the noble metal tip 21, there is no need to perform discriminative work on the central electrode base material 20.

Title: Paper feeder
Inventor: KATO HIROYUKI
IPC: B65H3/06
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To suppress noise of gears in a paper feeder in which the rotation of a conveying roller is transmitted to a paper feed roller through a planetary gear mechanism. SOLUTION: A sun gear 51 engages with the gear of a conveying roller, and two planetary gears 55, 57 engaged with the sun gear 52 are supported on an oscillating frame 53 coaxial with the sun gear 51. A paper feed gear 61 of a paper feed roller has a notch part 61a. When the conveying roller is rotated reversely, the planetary gear 57 pushes up a gear 63 capable of freely oscillating on the shaft 67 to engage it with the paper feed gear 61. When a specified amount of paper sheets is conveyed in this state, and then the conveying roller is rotated forward, the planetary gear 55 engages the paper feed gear 61 to rotate the paper feed roller continuously.  At this time, since the notch part 61a of the paper feed gear 61 passes through the position facing on the gear 63, but the gear 63 is separated from the paper feed gear 61 by its own weight, the gear teeth of both gears do not strike each other not to generate noise. When the notch part 61a faces on the planetary gear 55, the paper feed roller is stopped.

Title: Engine stopping device by welding rod operation only
Inventor: ANDOU KENJIROU
IPC: B23K9/073
Filed: 1980-08-08
Abstract: PURPOSE: To improve welding work efficiency especially at high work places in case of a remote-control-stopping of an engine welder or generator welding machine by enabling an engine to be stopped only through the deposit process of a welding rod.  
     CONSTITUTION: When the engine of an engine welder needs to be stopped in high place work, sticking a welding rod by welding to an electric conductor closes a contact at CRX, thereby opening a contact B of a relay XC and further closing a contact B of a relay X2. And it closes a contact B of a relay X1, setting a circuit of a timer T1, because the voltage in a cabtire cable 4 varies in such a manner that it's 84 volts at a high speed run, 24 volts during welding work, and 0 volt during welding rod deposit. After a time interval (about two seconds), battery electric current flows through X1 and T1 to operate a solenoid SR2, which removes a knocker 1D so that a control element 1 may return to the low speed position. With this low speed condition, the engine cools off to stop itself finally.

Filed: 1978-09-11
Abstract: PURPOSE:To ensure a quick detection of the fault of the display linking function even when no linking information is given by supplying the device test information to the blank word which is transmitted when no information is transmitted. CONSTITUTION:In the remote control equipment in which one master station 2 and plural slave stations 3-1-3-N are connected to the loop-type transmission line 4, the blank word having no information contained in the transmission word is formed with only the synchronous signal and the W code. Then the test position is provided for each slave station, and the test word is set up to transmit the test position to give decision via the W code for identity of the test code. And when no inter-station linking is given, the master station transmits the test word including the control command of the test position of one slave station. This command is checked whether it is transmitted between slave stations in the normal way. And in case some fault is detected, the necessary linkage is given immediately to the faulty slave station.

IPC: H02K15/16
Filed: 1994-05-25
Abstract: PURPOSE:To prevent the deformation of an insulating board by bringing a part of the insulating board into contact with the outer end face of the core, and to keep the balance of the rotor by setting a constant length of winding at each part. CONSTITUTION:An insulating board 23 is formed of an insulating material, e.g. a resin material, to have a planar outline identical to that of the correction members 24, 25. A winding constituting a rotor 5 is then applied under a state where the insulating board 23 is positioned at the outer end faces of the correction boards 24, 25 with the region provided with a protrusion facing a core 6. Since the protrusion abuts against the outer end face of the core 6, a gap (g) is ensured even if the tension of winding is superposed thus preventing deformation of the insulating board 23. Consequently, the length of winding is made constant at any position of the armature core 3 and the correction members 24, 25 are held at predetermined positions without inclining thus keeping balance of the rotor.
