IPC: H05K1/02
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To decrease defects at the time of mounting a package on a socket, etc., by setting pins upright at intersections of a mesh-like pattern formed on a pin installation face. SOLUTION: A PGA type integrated circuit package 1 is constituted of a package body 11 and a plurality of pins 12. A bottom face of the package body 11 is a pin installation face 11a and an integrated circuit is molded in the package body 11. On the pin installation face 11a of the package body 11, a mesh-like pattern 11b is formed. The pins 12 are set upright on the pin installation face 11a, with one end each of the pins 12 connected to the integrated circuit. The pins are located at intersections of the mesh-like pattern 11 formed on the pin installation face 11b. Therefore, the bending of a pin 12' can not only be easily found when viewed from above the pins 12 in the direction crossing at right angles with the pin installation face 11a with the mesh-like pattern 11b used as a guide, but also be easily corrected using the mesh-like pattern 11b as a reference.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To sell thin merchandise, and to contribute to the variation of a merchandise housing device by providing an adjusting piece for making an opening narrow for adjusting the size of the opening. SOLUTION: An adjusting piece 11 is shaped like a plate, and adjusting piece safety lugs 11a are constituted at the both edges of the adjusting piece 11 so that L-shaped vertical pieces can be bent inside. Deformed holes 4c are constituted at the both edges of the rear part of an opening edge 4a of a merchandise housing case 4. Protrusions are pieces projecting downward inside the deformed holes 4c. The protrusions are constituted like a recessed shape in side so that interfitting parts can be obtained. When the adjusting piece safety lugs 11a of the adjusting piece 11 are inserted into the deformed holes 4c of the merchandise housing case 4 and moved to an opening 6 side, the adjusting piece safety lugs 11a are interfit into the interfitting parts, and the adjusting piece 11 is fixed.  Thus, the opening 6 can be made narrow so that it is possible to facilitate a counter measure to even thin merchandise. Thus, the opening 6 can be made narrow only by mounting the adjusting piece 11.

Title: Semiconductor memory device
Inventor: TAKEUCHI SUSUMU
IPC: H01L27/088
Filed: 1987-03-10
Abstract: PURPOSE:To form a memory cell having small occupying area by forming an access MOS transistor and an inverter MOS transistor on sidewalls of a groove formed on a substrate. CONSTITUTION:The gate 19 of an inverter transistor is in contact through a thin oxide film with the left sidewall of a groove formed selectively in a silicon substrate. An N<+> type diffused layer 20 forms a drain, and a source is formed in the bottom of the groove. Accordingly, the parts in contact with the left and right side walls of the groove are utilized as the channel regions of the inverter transistor. Since the transistor is formed perpendicularly on the sidewalls of the groove in this manner, an occupying area can be reduced to the degree of the thickness of the gate 19. A gate 19' is in contact through a thin oxide film with the sidewall of the groove, and a semiconductor substrate of the lower part is utilized as a channel region. An n<+> type diffused layer 20 disposed at the right lower part of the gate 18' forms a drain, and an n<+> type diffused layer 14 disposed at the left side of the gate 18' forms a source. Therefore, the occupying area of the access transistor can be reduced to the degree of the thickness of the gate 18'.

Title: Controller of dc power supply for battery charging
Inventor: ARAI NORIHIRO
IPC: H02J7/02
Filed: 1992-02-07
Abstract: PURPOSE:To prevent abnormal heating of battery due to ripple current component by obtaining the sum of absolute effective values of ripple current components flowing into/from the battery and controlling an automatic voltage regulator based on thus obtained sum to lower the charging voltage for a battery thereby suppressing the ripple current components. CONSTITUTION:Ripple current components i1 and i2 flowing, respectively, into/ from a battery 5 are detected through a shunt resistor (SH2) 4 for detecting battery current. An effective ripple current value detecting circuit 7 then calculates the sum of the effective values of the ripple current components i1 and i2. A comparator 10 compares the value detected through the detecting circuit 7 with a value preset by a setter 11 and when the former exceeds the latter, an automatic voltage regulator 9 functions to control an AC/DC converting section 1 to lower the output voltage. Consequently, ripple current components flowing into/from the battery 5 is suppressed and service life of a battery is prevented from becoming short.

Filed: 1982-04-06
Abstract: PURPOSE:To obtain a sealed small battery having an excellent electric-discharge characteristic by preventing any damage to a separator by making the surface of a negative mixture packed in a negative can which faces the separator to have a flat form. CONSTITUTION:As the result of being pressed with a bottle having a flat end surface, a sealed small battery has such a constitutional form as indicated in the figure. There are no parts protruding from the surface of a negative mixture 14 which faces a separator, and rough surfaced grains all are crushed and densely packed. Since the negative mixture 14 is packed. Since the negative mixture 14 is packed in a flat form without bumping against a separator 13 which separates a positive electrode from a negative electrode, there is no possibility that the separator 13 is damaged. As a result, an excellent electric-discharge characteristic can be realized by preventing any loss of the capacity which might be caused by internal short-circuit electric discharge.
