Title: Laminating method of thin sheet
Inventor: HASHIMOTO KAORU
IPC: B32B37/00
Filed: 1979-12-06
Abstract: PURPOSE:To easily form an insulating film on an iron core for winding of a transformer by a method wherein a raw sheet consisting of two layers of a metallic thin sheet and a raw sheet of an insulating thin sheet are laminated and sintered. CONSTITUTION:Polyvinyl butyral and di-n-butyl phthalate are added to the alloy powder of Fe-6.5% and Si and an organic solvent is added to form a slime. At the same time, another slime is formed in the same way by using a blended powder, composed of magnesia, silica, alumina and barium oxide. With these two kinds of, slimes, raw sheet is formed by means of a tape casting method, respectively. After these sheets are dried in a room temperature, they are punched in a specified shape, laid one upon another alternately as one set of two kinds and are pressed in approximately 120 deg.C to complete a close adherence. Following this, after they are dried in the temperature of approximately 150 deg.C, they are sintered in H2 in the temperature of approximately 1,350 deg.C to complete it. During this constitution, it is effective when the difference of a thermal expansion coefficient between a thin sheet and an insulating material is made small, and each is made to react mutually in a certain extent during a sintering.

Title: Method and device for bonding pellet
Inventor: SHIMATA TSUTOMU
IPC: H01L21/52
Filed: 1978-12-25
Abstract: PURPOSE: To obtain identical products of the same kind by a method wherein a pellet is placed on a frame on the conveying line in two rows in a reverse direction and connecting work is carried out so as to be consistently assembled.  
     CONSTITUTION: A pellet facing upward in the direction of an arrow is transferred by a head 3A to an intermediate loader 2 then to the lead frame on a line A by a head 3B in this state. After the pellet has been transferred by the head 3A to the loader 2, it is turned 180° making the arrow facing downward, then transferred by the head 3B to the frame on a line B. By repeating this process by turns, each wire connecting head on the lines A and B does the connecting work while facing each other, thus making entirely identical products. The pellet direction of the lead frame on each line is likewise symmetrical mutually against the direction into which the resin flows in a resin sealing device 5, and there can be no difference in quality.

Title: Assembly method for electron gun
Inventor: KOUSHITA YAICHIROU
IPC: H01J9/18
Filed: 1980-11-12
Abstract: PURPOSE:To economically obtain an electron gun whose change of perveance caused by the dimensional ununiformity in the assembly process is small by combining a cathode and a focussing electrode, then correcting the relative position between the cathode and an anode, and fixing the anode. CONSTITUTION:A cathode cylinder 1 is fixed to a focussing electrode 3 through a cathode support body 2 and a cathode frame is assembled. An anode support plate 11, cathode frame support body 6, heater electrode plate 7, electron gun support body 8, and vacuum enclosure ceramics 9a-9d are laminated alternately. Then a vacuum container 10 is assembled by brazing every part on their contact surface.

As a result, the dimensional ununiformity in the assembly process is absorbed by the post process and the change of perveance can be reduced.

Title: Multiplexing method
Inventor: TAKEGUCHI YORIYASU
IPC: H04J3/22
Filed: 1985-07-18
Abstract: PURPOSE:To reproduce a sound which contains no peak sound by a normal reproducing device even when N-bit acoustic information is transmitted by substituting the low-order K bits of acoustic information which is divided by N bits with nonacoustic data and transmitting or recording the information. CONSTITUTION:A data sequence A=(a0) of nonacoustic information is ORed exclusively with a data sequence P=(p0) generated by an M sequence generator 2 to obtain b=(a0+p0). An exclusive OR computing element 14 performs demodulation firstly. Then, descrambling is carried out by an exclusive OR computing element 15. Namely, the data sequence B=(a0+b0) and data sequence P=(p0) are ORed exclusively to obtain A=(a0+p0+p0)=a0. Consequently, K bits of the original nonacoustic information are reproduced. Even when all bits of information from a transmission system are applied to a DA converter 11, the spectrum of the least significant digit bit is flat, so acoustic information outputted through a low-pass filter 12 is reproduced as a sound having no peak sound.

Title: Inspecting method for semiconductor nonvolatile memory
Inventor: IHAYAZAKA SHIGEKAZU
IPC: G11C17/00
Filed: 1982-09-13
Abstract: PURPOSE:To exclude an MOS type memory, which holds a memory defectively, by utilizing thermal stress applied during an assembly manufacturing process by previously writing a predetermined information to a semiconductor chip under a wafer state, mounting the chip to a package and reading the information. CONSTITUTION:When manufacturing a large number of FAMOS transistors, floating-gates in which there are charges and ones in which there is no charge often mix in the floating-gates constituting the transistors. Since a special aging for a prolonged term is required in order to discriminate transistors defectively holding charges, productivity is lowered. Consequently, when the transistors are still under the wafer state, each chip is tested electrically, predetermined data are written only to acceptable chips, a wafer is cut to a chip state, the data are read, and the chips are regarded as acceptable ones when data before and after the reading do not change. Accordingly, the productivity of the transistors is improved.

Abstract: PROBLEM TO BE SOLVED: To improve the reduction effect of an earthquake response by separating an external frame and an internal frame extending over a plurality of floors on the lower layer floor of a structure, separating the internal frame and a foundation section and installing a damping device between both the internal frame and the foundation section. SOLUTION: Outer peripheral frames 2, 2 such as columns and internal frames such as slabs 3... are separated extending over a plurality of floor sections on the lower layer floor A of the structure 1. The axial rigidity of the external frame 2 is maintained, and made to resist the overturning moment of the whole structure 1. Internal frames such as internal columns 5, 5 and a foundation section 4 are separated, and damping devices 8 are mounted among both the internal frames and the foundation section 4. Accordingly, horizontal rigidity is reduced on the lower layer floor A of the structure 1 and a period is lengthened while horizontal deformation collected on the lower layer floor A is collected and damped by the damping device 8. Thus, the reduction effect of an earthquake response can be increased.

Title: Combustion apparatus
Inventor: WATANABE TOSHIYA
IPC: F23D14/02
Filed: 1988-06-28
Abstract: PURPOSE:To uniformly distribute pilot flame air in the longitudinal direction of flame hole plates for stabilizing pilot flames, reducing combustion noise, and improving the combustion performance by providing spaces between inlets of pilot flame air and the flame hole plates, and by causing pilot flame air to jet to the side walls of the flame hole plates. CONSTITUTION:Flame hole plates 2 are located on the downstream side of evaporation compartments 1. Pilot flame air access paths 12 are furnished along the both sides of the flame hole plates in the longitudinal direction, and connected to secondary air compartments 5 through the pilot flame air holes 6 that are perforated on the upstream sides of the pilot flame air access paths 12. Slant secondary air holes 7 are furnished on the downstream sides of the air compartments 5 to blow out air diagonally into the pre-mixed gas, that spouts from the flame hole plates 2, and perforated so as to form a number of continuous ridges. Thereby, after the secondary air enters the air compartments 5, and a portion of it is blown out from the pilot flame air holes 6 at the right angle against the spouting direction of the pre-mixed gas from the flame hole plates 2, the secondary air forms pilot flames F1 passing through the air access paths 12. At this time, the pilot flame air is straightened before it reaches the flame hole plates, and spouts uniformly from the horizontal surfaces of the flame hole plates in the longitudinal direction so that the pilot flames F1 are stabilized. The remaining part of the air spouts from the slant air holes 7, and forcedly mixed with the pre-mixed gas to form flames F2.
