Title: Multilayer printed circuit board
Inventor: TOMIZAWA SHIGERU
IPC: H05K3/46
Filed: 1989-01-07
Abstract: PURPOSE:To mount a LCC type electronic component which can be mounted in high density but is difficult to absorb a stress at a soldered part with high reliability without solder isolation by pressuring, heating and laminating a prepreg and a surface layer copper foil through an elastic layer. CONSTITUTION:Prepregs 22 are laminated on both side faces of an inner layer circuit board 21 formed in a predetermined pattern of a copper foil 1, elastic layers 24 made of porous fluorine resin are interposed between the prepreg 22 and the surface layer copper foil 23, pressurized, heated and laminated. The elastic layer 24 is formed by coating the surface of porous fluorine resin 25 having 300mum of thickness with resin 26 made of heat curable epoxy resin of a stage B of the same material as that of the prepreg with 10mum of thickness. Since the porous fluorine resin has a small elastic modulus and is easy to absorb a stress so as to absorb the stress applied to a soldered part, the solder crack of the soldered position of the soldered part to the electrode of a LCC type electronic component is eliminated to be mounted in high reliability.

Title: Structure of mounting device for heat shield plate of exhaust pipe
Inventor: SUZUKI NOBUYOSHI
IPC: F01N13/14
Filed: 1990-01-10
Abstract: PURPOSE:To avoid undercut and prevent torsional deformation by welding a base part of a flange, which has been formed through bending both ends of a heat shield plate in the bending direction so as to separate from an exhaust pipe, to the exhaust pipe abutting to it. CONSTITUTION:A base part 13a of a flange 13, which is formed by bending both ends of a heat shield plate 12 in the bending direction so as to separate from an exhaust pipe 11, is welded to the exhaust pipe 11 abutting to it. Thus, it is possible to avoid concentration of welding heat at a weld zone and to prevent generation of undercut, because welding heat is easily conducted from the weld zone to the rest part of the heat shield plate 12. In addition, the flanges 13 contribute to improvement of the stiffness of the heat shield plate 12. Consequently, even if external force is applied to the heat shield plate 12, noise due to contact of the heat shield plate 12 with the exhaust pipe 11 caused by deformation of the heat shield plate 12 is not generated.

IPC: G01R31/302
Filed: 1994-01-12
Abstract: PURPOSE:To measure transfer function correctly even in the middle of a network. CONSTITUTION:Signals are fed from a network analyzer 18 to the input terminal 16 of a distributed constant network 11. Radio wave radiated from the network 11 is received at each point (x, y) on an observation plane 31 facing the network 11 and fed to the analyzer 18 where the transfer function H (x, y, fi) between each point (x, y) and the network 11 is measured. Similarly, the transfer function H (x, y, f1) to H (x, t, fm) are measured for observation frequencies f1 to fm. The transfer functions are then subjected to inverse Fresnel transform and the converted data I (X, Y, f1) to I (X, Y, fm) are stored in memories 361 to 36m. A control section 37 designates a measuring point (X, Y) on the network 11 and reads out a corresponding data from the memories 361 to 36m. The data thus read out is presented on a display 39 while furthermore subjected to inverse Fourier transform and a waveform is presented on the display 39.

Title: Grinding method in vertical duplex head surface grinder
Inventor: NISHIO KIYOSHI
IPC: B24B7/17
Filed: 1986-01-09
Abstract: PURPOSE:To enable prevention of floating up and jumping up of a work, by a method wherein, upon completion of grinding, an upper grinding stone is stopped on the way to a given backward movement position once, and the feed of a grinding solution is stopped or decreased to discharge a work momentarily. CONSTITUTION:Upper and lower grinding stones 8 and 9 are rotated in a stage in that a distance therebetween is increased fairly over the thickness of a work W before machining, and the work W engaged with a holding hole 10 a of a carrier plate 10 for holding is indexed and inserted. The upper grinding stone 8 is lowered for cutting, and both surfaces of the work W are ground by means of the stones 8 and 9. When the work is ground to a given size, a feed is stopped to effect spark-out grinding. After grinding is completed, the upper grinding stone 8 is slightly moved backward toward above and stopped one, and simultaneously, the feed of a grinding solution is stopped. Through swinging of the carrier plate 10, the work W is momentarily discharged from between the two grinding stones 8 and 9. This constitution prevents jumping up and floating up of the work owing to the grinding solution, also prevents the occurrence of double grinding, and permits precise machining of the work.
