Title: Printed circuit board
Inventor: NAGATA HARUTO
IPC: H05K1/11
Filed: 1992-07-17
Abstract: PURPOSE:To reduce generation of the defect of Manhatten phenomenon of chip parts at the time of soldering the chip parts, in a printed circuit board for surface-mounting the chip parts. CONSTITUTION:The size of a land pattern 7 around the edges of a board 1 or the periphery of a large parts in which chip parts tend to lift at the time of soldering is made larger than that of another land pattern 2 as the companion of the land pattern 7. As a result, the adhesive power of cream solder and the tensile force at the time of melting become larger than those of the land pattern 2. Therefore, it is possible to reduce the Manhatten phenomenon of a chip.

Title: Debugging device for microprocessor
Inventor: YOSHIDA YOSHIO
IPC: G06F11/28
Filed: 1986-08-14
Abstract: PURPOSE:To obtain a debugging device that can measure an accurate coverage of a microprocessor having a prefetching function for instruction causing the pipeline processing, by having comparison of contents between a coverage memory and a flag memory. CONSTITUTION:The execution of a target CPU 1 is started after 3-state buffers 9, 14 and 15 are turned off together with buffers 6, 12 and 14 turned on respectively. An instruction tracking circuit 3 detects an instruction with which an address flow becomes discontinuous and then activates the preset input LD of a presettable counter 2 and applies a clock CK pulse to preset again the address of the CPU 1. Thus data are written to a coverage memory 7 while the execution of a fetched instruction is detected. In case '1' is already written in a range of the coverage measuring addresses of the memory 7 and the contents of the memory 7 are changed to 0 from 1, it is considered that the relevant address has a hit. Thus it is possible to extract a hit factor and an unhit address by comparing the contents of a flag memory 16 stored previously with the contents of the memory 7.

Filed: 1985-08-29
Abstract: PURPOSE:To enhance the durability of an armature, by providing a recess on the armature at the portion thereof touched by a hammer in order to increase the contact area with the hammer. CONSTITUTION:Printing is conducted by a method wherein a hammer 19 hits a type 18 on a daisy wheel 17. At this time, a recess portion 33 provided on a touched face 32 of a head 30 comes into impact with an arm stopper 24 at the inlet corners thereof because the length (a) of the inlet portion of the recess 33 is formed slightly less than 2r, where (r) is the radius of the arm stopper 24. Namely, the head 30 of an armature 21 is brought into linear contact with the arm stopper 24 at two points, which results in the doubled contact area. Therefore, the impact-resiliency which is applied to the touched face 32 of the armature 21 when the armature 21 pushes the hammer 19 is halved. As a result, the wear resistance of the touched face 32 is enhanced, which realizes the improved durability of the armature 21.

Title: Method and apparatus for hot isotactic molding in oxidative atmosphere
Inventor: ASARI AKIRA
IPC: B28B3/00
Filed: 1988-07-30
Abstract: PURPOSE:To simplify structure, to make maintenance easier and to improve a preheating efficiency by inserting a material to be processed into a heat-generating member of a heating device and molding the same, after removing a preheating device that has preheated the heat-generating member of the heating device up to a predetermined temperature. CONSTITUTION:A preheating device 14 is inserted into a high-pressure vessel 1, and preheating is effected in ambient air. When a temperature within the vessel 1 i.e. the temperature of a heat-generating member 10 for heating reaches a temperature at which power can be supplied, a current is simultaneously fed to the heat-generating member 10 and thereafter the preheating device 14 is drawn out of the vessel 1. Subsequently, a material 20 to be processed is inserted into a heating device 9, and high-pressure gas is confined in the vessel 1 to mold and process the material by heating the same up to a processing temperature in an oxidative atmosphere. Accordingly, owing to the preheating device 14 which is freely attachable, it is sufficient enough to install only a power source device adaptable for the heat-generating member 10 in a high-temperature condition, and this is more economical. The structure within the high-pressure vessel is also simplified to make maintenance easier. Furthermore, a preheating efficiency can be enhanced by direct heating through the preheating device.

Title: Method for forming poly crystal silicon film
Inventor: KITSUNO YUTAKA
IPC: H01L21/02
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To easily and positively form polycrystal silicon film by applying a specific hydrogenation silicon in a liquid shape onto a substrate and applying energy beams to a-Si film formed by decomposition reaction by a thermal history containing a temperature-increase process. SOLUTION: When hydrogenation silicon in a liquid shape containing Sim H2m +2 and Sin H2n (m and n are integers (m>=5 and n>=4)) is applied to a substrate and is subjected to decomposition reaction by heat history, a-Si film is formed via a nonunifom reaction by thermal energy when the hydrogenation silicon goes through a thermal history including the temperature-increase process. Then, since many (-SiH2 -)n (n is an integer which is equal to 1 or larger) connections exist in the film in the middle process of temperature increase, only two connection hands out of four connection hands of one Si are connected to the other Si atom in many cases immediately after hydrogen leaves in the temperature increase process when crystallizing the a-Si film. Therefore, recombination and structure relaxation easily occur at the time of crystallization, thus forming Poly-Si film with a large crystal particle diameter and less lattice defect.
