Title: Semiconductor resistor device
Inventor: IWAMOTO YOSHIHIRO
IPC: H01L21/822
Filed: 1982-05-31
Abstract: PURPOSE:To improve the error of resistance value due to the scatter of resistance and the change of the width of a depletion layer largely, and to obtain the semiconductor resistor device having extremely high accuracy by connecting P type and N type semiconductor regions formed through the diffusion of P type and N type impurities in parallel as resistance elements. CONSTITUTION:The first (P type) and second (N type) semiconductor regions shaped by diffusing the P type (one conduction type) and N type (a reverse conduction type) impurities are connected in parallel as each resistance element forming a ladder resistance net. RP0-RPn and rp1-rpn-1 are the resistance elements formed by the P type semiconductor region, and RN0-RNn and rN1- rNn-1 are the resistance elements shaped by the N type semiconductor regions. According to such constitution, the change of the resistance value of each diffusion resistance of P type and N type due to the change of input signals IN (a1+2a2+...+2n<-1>an) is mutually denied, and the resistance value can be kept  constant without regard to the level of the input signals IN. The scatter of the  resistance value in a manufacturing process can be reduced because the P type and N type diffusion resistance are connected in parallel.

Title: Manufacture of flexible printed wiring board provided with terminals
Inventor: SATO SUKEHISA
IPC: H05K1/02
Filed: 1989-04-14
Abstract: PURPOSE:To make a preliminary treatment unnecessary and to perform the solder plating of terminals at the same time by performing a solder dip while forming a bending part after removing a base of terminal parts and an adhesive agent. CONSTITUTION:A base 3 and a copper foil 4 are bonded and a circuit pattern is made by a printing wiring technique. While fixing a terminal part 2, a grinder or a buff is brought near the base 3 gradually which scrapes or polishes the base 3 and an adhesive agent to remove them. The copper foil 4 is crumpled into a ball so as to make a bending part 4''. Next, the bending part 4'' is subjected to a solder dip. Thus, the bending part is formed after removing the base and the adhesive agent, after which a solder dip is performed. Accordingly, a solder comes in good contact to the terminals and a solder plating of the terminals can be carried out at the same time.

Title: Manufacture of semiconductor
Inventor: TONISHI SHIGEJI
IPC: H01L21/027
Filed: 1988-04-15
Abstract: PURPOSE:To enable a precise printing of a very fine mask pattern on a semiconductor wafer, by obtaining an X-ray highly parallel and of single wave length utilizing two times Bragg's reflections in an optical system of an X-ray stepper. CONSTITUTION:A parallel flat plates and double crystals monochrometer 1-1 has double reflection surfaces 1-4 and 1-4 which are cut out from a single crystal, and these reflection surfaces face parallelly each other and also are placed at a Bragg's reflection angle thetaB to an incident X-ray 1-2. The Bragg's reflection angle thetaB is calculated from a distance between the two crystal surfaces and wave lengths of incident and emitting X-rays. In this way, the incident X-ray 1-2 is emitted as a highly parallel monochrome X-ray 1-3 after repeating the Bragg's reflections twice, and because the directions of incident and emitting rays are the same, a mask at the tip end of an optical system can be easily prepared.

Title: Automatic braking force regulator
Inventor: INOUE DAIZOU
IPC: B65H59/38
Filed: 1983-05-25
Abstract: PURPOSE:To preven breaking of linear member, biting of winding and loosening of linear member by detecting the residual amount of linear member wound around a feed spool while applying the optimal braking force onto said spool upon completion of winding. CONSTITUTION:A residual linear material detector 15 comprised of a tachogenerator 9 for detecting the rotation of a feed spool and a converter for converting the output from the tachogenerator into an electric signal corresponding with the residual amount of linear material wound around said spool is connected to a motor 2 for the feed spool and the output from said detector 15 is provided through pneumoelectric converter 18 and pneumo-hydraulic converter 19 to a disc brake 20. Since the optimal braking force corresponding with the residual amount can be applied onto the feed spool upon completion of winding, cutting of linear material or biting of winding due to abrupt braking can be prevented while loosening of linear material due to insufficient braking force can be prevented.
