Title: Closed cross section structural body for automobile
Inventor: SAKAI JUN
IPC: B23K9/00
Filed: 1992-05-08
Abstract: PURPOSE:To protect the gap of a joint with galvanization so as to prevent crevice corrosion and enhance rigidity by joining a first closed cross section structural body longitudinally to a second similar closed cross section structural body of different plate thickness, and continuously welding their joint, the first closed cross section structural body comprising galvanized stainless steel plates laid one over the other and joined together. CONSTITUTION:A first closed cross section structural body 10 comprises a channel member 11 made by press molding of a galvanized stainless steel plate and a lid body 12 made of galvanized stainless of the same thickness as the plate of the channel member 11 and laid over the channel member 11, both of which are continuously welded at their joint 13 by MIG method. A second closed cross section structural body 20 comprises a channel member 21 of different plate thickness from that of the closed cross section structural body 10 and a lid body 22 of galvanized stainless laid over the channel member 21, both of which are continuously welded at their joint 23 by MIG method. The MIG does not pose the problem of corrosion that could be caused by residual flux. Since the length L by which fillet continuous welding is done is sufficient, galvanized films 14, 24 remain sufficiently to avoid crevice corrosion.

IPC: G06F15/18
Filed: 1993-06-14
Abstract: PURPOSE:To provide desired input/output relation using the small number of arithmetic elements by executing plural arithmetic operations in time-division manner and successively and time-sequentially outputting the output values. CONSTITUTION:(j)=0 is defined first, psi(xi+epsilonj) is simultaneously outputted from respective first intermediate layer arithmetic elements A1i respectively, a weighing coefficient lambda<i> is multiplied with them by respective multipliers and they are sent to a second intermediate layer arithmetic element A20 as lambda<i>psi(xi+epsilonj). In the meantime, synchronized with it, the output value (j) is supplied from a synchronization element A40 to the second intermediate layer arithmetic element A20 as well. The second intermediate layer arithmetic element A20 calculates Xx with the sum of all the input signals as input (x) and supplies it to an output element A30. Similarly, the operations are successively repeated for cases from (j)=1 to (j)=2n. As a result, (2n+1) pieces of output corresponding respectively to the cases of (j)=0 to (j)=2n from the second intermediate layer arithmetic element A20 are inputted to the output element 30 in the time- division manner. The output element 30 adds and outputs all of them.

Title: Permanent magnet rotor
Inventor: TAJIMA FUMIO
IPC: H02K1/27
Filed: 1981-09-11
Abstract: PURPOSE:To reduce eddy current loss and prevent the decrease of the efficiency, by providing slits orthogonal to the axial direction of a rotary shaft and extending to the circumferential direction on a non-magnetic metallic cover arranged on the outer periphery of permanent magnets. CONSTITUTION:A yoke 3 and permanent magnets are successively arranged on the outer boundary of the rotor shaft 2, and further the non-magnetic metallic cover 7 is arranged on the outer periphery of permanent magnets 4. Hereupon, for the non-magnetic metallic cover 7, one provided with slit parts 7a at fixed intervals along the circumferential direction is used. Thus, since the passage of the eddy current flowing to the non-magnetic metallic cover 7 is subdivided by the existance of the slit part 7a, the passage of the eddy current as a whole is enlarged resulting in the reduction of the eddy current loss. Besides, the slit part 7a can be also provided continuously along the circumferential direction of the non-magnetic metallic cover.

Title: Impact dot head
Inventor: TAKEUCHI TAKASHI
IPC: B41J2/265
Filed: 1992-06-03
Abstract: PURPOSE:To improve the reliability at a low cost by supporting with a spring a wire guide arranged at a position closest to a base of a print wire of an impact dot head. CONSTITUTION:During printing operation, a wire guide 12 arranged at a position closest to a base of a print wire 7 is movable elastically due to the reaction force of the print wire 7 against a guide hole 14, so that unnatural bend to be given to the print wire 7 is prevented. Accordingly, friction among the print wire 7 and wire guides 12, 13 is reduced. As a result, in addition to high energy efficiency, abrasion will be reduced and stress amplitude of the print wire 7 also becomes small, so that lifetime of an impact head 2 will be prolonged. Generally, the print wire 7 will be driven with frequency 1-2KHZ, but when characteristic frequencies of the wire guide 12 and a bent plate spring 22 are released from this frequency band area, the wire guide 12 does not resonate with the drive of the print wire 7.

Filed: 1989-06-05
Abstract: PURPOSE:To facilitate enlargement of the effective area of a photovoltaic device, reduce power loss in electrodes and improve mass-productivity by a method wherein linear metal elements are fixed to the electrode forming surface of the photovoltaic device with conductive adhesive.

Title: Plate-like information recording carrier and its manufacture
Inventor: TANII KIYOSHI
IPC: G11B7/24027
Filed: 1989-06-05
Abstract: PURPOSE:To suppress the distortion and to obtain a disk whose mechanical characteristic is stable by applying a hot-melt adhesive agent to two pieces of plate-like substrates by a roll coating method and sticking them by setting an angle made by a linear stitch pattern generated on its surface to a specific value or above. CONSTITUTION:A hot-melt adhesive agent is applied in the linear direction onto the surface of two pieces of plate-like substrates 1, 2 by a roll coating method. At the time of sticking these substrates 1, 2 by opposing the application surfaces, an angle made by a linear stitch pattern formed on the surface of the application surface is set to >=30 degrees. Accordingly, the roll mesh after sticking has an angle and irregularity of a large period caused by moire fringes are not generated. In such a way, the generation of a distortion of a disk can be suppressed and the disk whose mechanical characteristic is stable can be obtained.

Abstract: PURPOSE:To protect an antenna and to reduce the side lobe level, by constituting a radome with two plane bodies of a specific wavelength and by setting an angle made by plane bodies so that linearly polarized waves from the main beam direction of the antenna are incident at a Brewster's angle. CONSTITUTION:In a radome 1 consisting of two plate bodies about 1/4 wavelength long, two planes make such angle theta that radio waves coming from the main beam direction of an antenna 2 are incident at a Brewster's angle thetaB. By the characteristics of the radome 1 in this constitution, radio waves coming from the main beam direction are not reflected and are incident to the antenna at a power transmittivity P of a maximum, and most of radio waves coming from the direction other than that of the main beam, namely, from the side lobe direction are reflected, and the incident angle to the antenna is reduced, and the side lobe level is reduced by this reduction.

Title: Switch circuit
Inventor: YOSHINO RYOZO
IPC: G01R31/28
Filed: 1987-06-08
Abstract: PURPOSE:To improve the reliability of a switch circuit by holding an output voltage much lower than the low output level of a front-stage differential switch circuit under the control of a power source side, and turning off the switch circuit regardless of the input of a rear-stage differential switch circuit to which the varied output is inputted. CONSTITUTION:When an IC 20 to be tested is in an input state, a control differential switch circuit 4 in an IC tester output driver 1 is held off. Namely, a high-level base voltage VB5 is applied to a transistor(TR) Q5 and a low-level base voltage VB6 is applied to a TR Q6, which is held off, so that the high level of the front-stage differential switch circuit 2 is determined by the base voltage VB1 to a TR Q1. In this state, pulse voltages are inputted as the voltage VB1 and the base voltage VB2 to a TR Q2 and then the waveform voltage of the VB2 is inputted to the IC 20 as it is, i.e. as a voltage Vi. The voltages VB1 and VB2 are therefore transmitted at a high speed and the operation measurement of the IC in a fast operation state is performed with high accuracy, thereby improving the reliability.
