Patent JP-H10256431-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: OKUNAGA MASASHI
IPC: H01L23/50
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To increase an adhesion strength between a moistureproof board and the main body of a package by burying the moistureproof board inside the main body of the package and forming an uneven section on at least one face of the board. SOLUTION: Between a bottom face of a recessed section 2 which will become a mounting face for a semiconductor element 2 and a bottom face of the main body 1 of a package, a moistureproof board 9 is buried. Due to the existence of the waterproof board 9, the penetration of water from a bottom face of the package through a resin bulk, through which water penetrates the package most easily, can be effectively prevented. The moistureproof board 9 is provided on its both faces with uneven sections 10 and thereby a contact area between the moistureproof board 9 and the main body 1 of the package increases and, at the same time, the adhesion between the moistureproof board 9 and the main body 1 of the package can be also increased due to an anchor effect of the uneven sections 10.  By this method, an adhesion strength between the moistureproof board and the main body of the package can be increased without deteriorating the function of the moistureproof board and thereby a semiconductor device with an excellent moistureproof property can be realized.

Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent circular lamp having a superior effect capable of maintaining the luminance flux rate in the service life of a lamp at a high level by specifying the tube wall load of a circular light emission tube in the fluorescent circular lamp. SOLUTION: Circular ligth emission tubes 1 and 2 are linked on a side which does not have electrodes 3 and 4, i.e., in the vicinity of the other side by means of a junction part 5, and a series of discharge path from an electrode 3 provided at one end inside the outer most annular light emission tube 1 to an electrode 4 provided at one end inside the inner most annular light emission tube 2 is formed.

Title: Magneto-resistance effect element
Inventor: KAMIGUCHI YUZO
IPC: H01F10/00
Filed: 1993-03-12
Abstract: PURPOSE:To provide a magneto-resistance effect element with high sensitivity, by forming at least a half-metal magnetic layer out of a pair of magnetic layers having a relative angle of magnetization shifted in an outer magnetic field. CONSTITUTION:In a magneto-resistance effect element, a non-ferromagnetic metallic layer 1 made of copper, and magnetic layers 2 and 3 made of NiMnSb deposited in different conditions and having different values of coercive force (Hc) are layered in an ion-beam sputtering method. When the magneto-resistance effect element is put in a magnetic field (H1) stronger than these coercive force values Hc1 and Hc2 (Hc1<Hc2), the magnetization becomes all parallel in the magnetic field. In addition, when a magnetic field (H2) magnetized reversely to the magnetic field (H1) is applied under a condition of Hc2>H2>Hc1, only the magnetic layer 2 having weaker coercive force is put in a reverse magnetic direction so that the adjoining magnetic layers 2 and 3 are put in a non-parallel magnetic state. Then, the change in electric resistance from the parallel to non-parallel states of the magnetization becomes larger, and a larger magneto- resistance effect can be obtained. A magneto-resistance effect element with high sensitivity can be obtained.

Title: Ribbon feed mechanism
Inventor: MINAGAWA HIROYUKI
IPC: B41J33/38
Filed: 1988-03-07
Abstract: PURPOSE:To reduce the generation rate of ribbon feed trouble (ribbon feed slip, ribbon jamming or ribbon breakage), by making ribbon feed speed constant by a speed control mechanism when a ribbon is fed by spacing driving force. CONSTITUTION:A ribbon cassette 1 is constituted so that ribbon feed driving force is obtained by the reciprocally moving a carrier 6 by utilizing a rack 4 and a pinion gear 5 and a ribbon is fed by a ribbon feed driving part 7 through a belt 3 and an automatic centrifugal pulley 2. When the reciprocating movement of the carrier 6 is slow, the automatic centrifugal pulley 2 is brought to such a state that the groove of the pulley 2 is widened by the belt 3 to which tension is given by a torsion roller 8 and a speed reducing ratio is made small. The number of rotations of the pulley 2 become high as the reciprocating movement of the carrier 6 becomes fast. At this time, the belt groove of the pulley 2 becomes narrow and the belt 3 is expelled to the outer diameter side to increase the speed reducing ratio and the pulley 2 becomes stable by constant rotary power. By this method, a ribbon feed speed is automatically controlled to a constant one.
