Abstract: PURPOSE:To enhance the reliability of a semiconductor device with good precision by a method wherein a notch is provided in an insulative film in the vicinity of each outer lead of a conductive pattern and the connecting parts of the points of the inner leads of the pattern are connected with the bumps of a semiconductor chip. CONSTITUTION:Outer leads 9 are respectively placed at each prescribed position on a circuit 15 on a printed circuit board 13 and are aligned to the circuit 15. Then, bonding tools 14 are applied to the leads 9 from the side of an insulative film 1 and while being heated and pressed, the leads 9 are mounted on the board 13. At least one place of a notch 10 is formed in the film 1 in the vicinity of each lead 9, whereby a tape carrier is bent at the position of the notches 10. Thereby, as the leads 9 can be adhered easily and closely to the circuit 15, a semiconductor device of a tape carrier system can be mounted on a printed fine pitch circuit board with very good accuracy.

Abstract: PROBLEM TO BE SOLVED: To improve the speed of the logical address generation of a computer system by predicting a logical address without using any RAM resulting in the increase of circuit amounts or power consumption. SOLUTION: A logical address generating circuit 110 generates a logical address from logical addresses 100 and 101, and a logical address predicting circuit 111 generates a predicted logical address 106 from logical addresses 100 and 101 and the logical address of a TLB1, and a comparator circuit 114 compares the predicted logical address with the logical address of the entry of the TLB1, and a selecting circuit selects the physical address of the entry of the TLB1 according to the compared result as a predicted physical address. Then, access to a CACHE 119 is performed with the address combined with the lower bits of the output of the logical address generating circuit 110.  The logical address predicting circuit 111 predicts each bit of the added result between the logical addresses 100 and 110 from an arithmetic operation using an arithmetic result obtained by limiting the number of carry propagating bits between the operands of the lower J bits of the bit to J and the bit value of the logical address of the entry of the TLB1.

Title: Semiconductor device and its manufacture
Inventor: II YOSHIKO
IPC: H01L21/768
Filed: 1992-08-17
Abstract: PURPOSE:To prevent deposits such as phosphorus, etc., from occurring on the surface of an insulating film by providing an insulating moisture-absorption- resistant film on the interlayer insulating film doped in high concentration with hygroscopic impurities.

Title: Lead frame for semiconductor device
Inventor: SUGIMOTO HIROSHI
IPC: H01L23/50
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent contacting between a lead which is not provided with insulating bond and a semiconductor chip by allowing the thickness of a part which is not provided with insulating bond provides to be smaller than the thickness of the lead of a part which the insulating bond of an inner lead provides. SOLUTION: An insulating bond 4 is applied near the tip end of an inner lead 2. The thickness of an inner lead at a tip end part 7 where an insulating bond 4 is applied is identical with that on an outer lead side. However for a range A, which overlaps with a semiconductor chip 5 of other inner lead 2 except for the tip end part 7, thickness is reduced by about 15 μm as compared to the tip end part 7 for providing a thin-wall part 3, forming a recessed part 8. Thus, even if slight inclination of the semiconductor chip 5 or a slight dispersion in thickness direction of a lead frame of the inner lead 2 occurs at bonding of the semiconductor chip, the inner lead 2 which is not provided with insulating bond 4 does not make contact with the semiconductor chip 5, and this results in the fixed and stable semiconductor chip 5.

Abstract: PURPOSE:To enhance the control of a lock lever in a paper feed device provided with tractor units in a printer, etc., by enabling the lock lever to be returned into its release position in association with the rotation of paper retainers provided to tractor frames in their releasing directions. CONSTITUTION:In a printer, paper retainers 6 in left and right tractor units 20 are secured such that the retainers 6 are covered over pin belts 4 and a sheet 23 to prevent the sheet 23 from coming off. Further, a lock lever 14 is rotated to a position where the control section 28 thereof abuts against the top surface of one of the paper retainers 6, and the cam section 13 thereof urges an upper clamp piece 18 which therefore clamps a support shaft 9 together with a lower clamp piece 17 to secure the tractor unit 20. In this condition when the paper retainers 6 are rotated upward to be held in their upright postures, the lock lever 14 is simultaneously rotated in the same direction so that the clamp of the support shaft 9 by both clamp pieces 17, 18 is released.

Abstract: PURPOSE:To obtain a proper rear wheel steering angle by holding an engaging part having engaging members on its both ends at an engaging body displaced in accordance with front wheel steering angle, and engaging the engaging part with either positive- phase or negative-phase transfer member in accordance with car speed. CONSTITUTION:An engaging part 3 having engaging members 301, 302 on its both ends is held at an engaging body 2 displaced in accordance with steering angles of front wheels 176, 175. The engaging part 3 is displaced to the right and left in accordance with car speed by a car speed actuator 4. During low-speed travelling, the engaging member 301 is engaged with a negative-phase transfer member 5, and rear wheels 866, 865 are displaced to negative-phase in accordance with the steering angles of the front wheels. During high-speed travelling, the engaging member 302 is engaged with an in-phase transfer member 6, and displaced to in-phase in accordance with the steering angles of the front wheels. During medium-speed travelling, the engaging part 3 is held in null position, and the rear wheels 866, 865 are not displaced. The rear wheels 866, 865 are thus properly steered by means of the steering angles of the front wheels 176, 175 and the car speed, and thereby steering operation becomes easy.

Title: Light source for projector and projector
Inventor: ITO SHIGEO
IPC: H01J29/04
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a compact projector in which a heat is hardly generated, and capable of preventing the periphery of a screen from becoming dark even in the case of enlarging/displaying. SOLUTION: Inside the liquid crystal projector 1, a liquid crystal panel 3, a thin- shaped panel FED 4 as a light source, a heat sink 5 and a projecting lens 6 are installed. A screen is shown by figure 25. The light source is made thinner in shape, so that the light source is more compact than the conventional one. The FED 4 is provided with a solid-state phosphor layer on the anode substrate of an outer jacket. Many cone-shaped emitters are installed on the inside face of a cathode substrate. Electrons are discharged by converging the electric field on the leading end of the emitter. As for the installation density of the emitter, the density in a part corresponding to the center of a light emitting area is the lowest, the density in the intermediate rectangular ring area follows the aforesaid density, and the density in the outer rectangular ring area is the highest.  Because of the optical aberration of the projecting lens 6, the center of the projected image is bright, but, the peripheral part of the image is dark. The number of emitters are more increased as the periphery area is darker so as to increase the luminance and to make the luminance of the whole projected image uniform while giving consideration to the influence of the light reduction at the periphery.
