Title: Method of preliminary soldering for ic lead
Inventor: SETA JUNZO
IPC: H01L23/50
Filed: 1986-02-03
Abstract: PURPOSE:To eliminate the need for an exhaust duct system by a method wherein a creamy solder is used for the elimination of flux application and wash processes. CONSTITUTION:Simultaneously with the going up of a left-hand scraper 13, a right-hand scraper 14 comes down and moves along the direction A indicated by an arrow, pushing out a creamy solder 12 to fill up a recess 15 provided on the surface of a specific fixing board 11. In this process, no creamy solder 12 wil stick to the surfaces of a fixing board 10 and the specific fixing board 11. An IC 16 with its lead 16a coated by the creamy solder 12 is sucked up by an adsorbing section 17 catching the molded portion of the IC 16. The adsorbing section 17 is caused to incline for exposure to an arrow-indicated non-contact heat beam 18. The creamy solder 12 melts, reaching the other face of the lead 16a for the completion of the preliminary soldering process. When soldering is completed for one of the sides, the adsorbing section turns around by 90 deg., for the accomplishment of preliminary soldering for each of the sides, one after the other.

Title: Manufacture of semiconductor laser device
Inventor: KAKIUCHI TAKAO
IPC: H01S5/00
Filed: 1985-02-05
Abstract: PURPOSE:To prevent characteristics of the device from deteriorating, by growing an active layer in the bottom between two stripe shaped projections. CONSTITUTION:After two forward mesa stripe shaped projections 9 are formed on an N-type InP substrate 8, an InGaAsP active layer 10 is grown. Next, after a P-type InP light confining layer 11 and P-type InGaAsP electrode contact layer 12 are grown, a forward mesa stripe shaped projection 16 is formed with anisotropic etching. Thereafter, a P-type InP burying layer 13 is formed and a P-side electrode 14 and N-side electrode 15 are formed. In this way, since hetero-junction interfaces on sides of the active layers 10 are not exposed to high temperature atmosphere on crystal growing, lattice defects do not result so that characteristics of the laser device can be prevented from deteriorating.

Title: Acceleration sensor
Inventor: KOSHIMOTO YASUHIRO
IPC: G01P15/18
Filed: 1993-02-08
Abstract: PURPOSE:To provide an acceleration sensor which is small sized and accurate and can detect acceleration in the three axial directions simultaneously by providing magnetic field sensors to surround a permanent magnet and detect the variation of magnetic flux. CONSTITUTION:This sensor detects the direction and the distance of movement of a permanent magnet 1, by comparing second higher harmonics of respective axes on a plane with each other, by the use of the same principle as that of a flux gate shaped magnetic field sensor. For example, if the magnet 1 is moved to the arrow mark side of X-axis, output of a magnetic pole bar 4a is increased and output of a magnetic pole bar 4b is decreased. Outputs of magnetic pole bars 4c, 4d arranged in the direction of Y-axis are not changed. In this way, two dimensional movement in the X-Y plane is obtained by comparing differences of output of respective magnetic pole bars 4a/4b and 4c/4d with each other. Further, displacement in the direction of Z-axis can be detected by comparing the components of detecting coils 5a-5d being wound on the respective magnetic pole bars 4a-4d, because the magnetic flux quantity changes regardless of the direction of the magnetic pole.

Title: Data processor
Inventor: KAJI NAOTO
IPC: G06F12/10
Filed: 1985-02-05
Abstract: PURPOSE:To attain plural main memory accesses with less hardware quantities with a data processor which performs the address conversion, by controlling the number of array elements to receive accesses in each cycle to the maximum number of elements that can be converted at a time. CONSTITUTION:A processing part 1 performs a vector operation. Array elements needed for operations are obtained by performing the address calculations from the head element address B and the inter-element distance D like B, B+D and B+2D and according to B+iXD (i=n-1, n: number of elements). In case the access is possible for maximum four array elements at a time in a vector processing mode, the 1st access is carried out with B, B+D, B+2D and B+3D and the 2nd access with b+4D, B+5D, B+6D and B+7D respectively. Then the 2nd access is also defined as B1, B1+D, B1+2D and B1+3D as long as B1=b+4D is satisfied. Then the value of B is increased by (DX4) for each machine cycle, and O, D, DX2 and DX3 are added to the value of B. Thus the element address is obtained for each access.

IPC: B31B25/60
Filed: 1993-01-13
Abstract: PURPOSE:To rationalize application of sealing agent in a reverse-cone-shaped package with an upper part opened by a method wherein an overlapping part with one of a radial side of a sector cone forming part extendedly formed is overlaid on a surface on the other radial side and an overlap width at an edge of the rear of the overlap part is adhered to the surface on the other radial side. CONSTITUTION:A body is determined in its outer shape by winding a blank 5 around a center and winding a sector cone forming part 6 around the center. The blank 5 is formed with an overlap part 7 so that one of radial sides 6a of the cone forming part 6 is extendedly formed while an overlap width 8 is formed on the rear at the edge. The overlap part 7 is overlaid on a surface of the other radial side of the cone forming part 6. An allowance part 11 where sealing agent is not applied is provided between the overlap width 8 on the rear of the overlap part 7 and the radial side 6a of the cone forming part 6, so that even if the sealing agent is excessively applied on the overlap width 8, the excess remains on the allowance part 11 but may not extend to a housing.

IPC: H02G5/08
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain a highly reliable current detector having simple structure which can be manufactured easily by transmitting an optical signal from a light source to a light receiving unit through an optical fiber coil having one turn or more disposed on the outer circumferential part of an insulating spacer. SOLUTION: Light emitted from a light source 63 is polarized through a polarizer 62 and passed through an optical fiber 61a and a connection terminal 60a to an optical fiber coil 20 disposed on the outer circumference of an insulating spacer 5. The incident light is subjected to Farady rotation due to a field induced by a current flowing through a high voltage conductor and then passed through a connection terminal 60b and an optical fiber 61b to an analyzer 64 where the rotational angle of plane of polarization is detected before the light is transmitted to a light receiving unit 65. Since the intensity of transmitted light varies depending on the magnitude of current flowing through the high voltage conductor, the magnitude of current flowing through the high voltage conductor can be measured, based on an output signal 66 from the light receiving unit 65.
