Title: Butt welding method with backing strip of bottom plate of storage tank
Inventor: FUKUI ICHIROU
IPC: B23K9/035
Filed: 1982-02-05
Abstract: PURPOSE:To prevent the generation of transverse cracks by penetration in the end parts of backing strips in butt welding with backing strips, by executing the root passes in the parts where there are no backing strips after the root passes in the parts where there are the backing strips. CONSTITUTION:Backing strips 10, 10' are arrayed in conformity with the shapes of bottom plates 11, 11', and the plates 11 are arrayed on the strips 10, 10'. The root gap (l) of the strips 10, 10' in this stage is set at >=10mm. to generate penetration. The root passes 12, 12' of the butt welding of the plates 11, 11' where there are the strips 10, 10' are exectuted. If the welding direction in this case is assumed to be the directions of arrows (a), (b) toward the end parts of the strips 10, 10', lack of penetration does not arise in the parts of arrows (c), (d). The root passes of the butt welding of the plates 11, 11' in the parts where there are no strips 10, 10', that is, the parts of the clearances between the strips 10 and 10' are executed. The root passes of the remaining butt parts of the plates 11, 11' are executed, whereafter the welding of the 2nd and succeeding layers up to the final layer is accomplished over the entire part of the butt parts of the plates 11, 11'.

Title: Manufacture of pattern for graded type shadow mask
Inventor: SEN TAKUROU
IPC: G03F1/00
Filed: 1984-02-02
Abstract: PURPOSE:To form easily a shadow mask pattern from a flat type mask pattern through contact printing by using a light-transmitting rotary disc which has a light shading section changing its shading area continuously from the optical axis of artificial parallel light rays toward the circumferential area. CONSTITUTION:The light from a light source 1 is spreaded through a lens 2 to form artificial parallel light rays 3 so that those light rays are irradiated on the screen on which a flat type shadow mask pattern 13, a contact printer 12, and a sensitive material 14 are arranged. And, between the light source and the screen, a light-transmitting rotary disc 4, which has a light shading section 6 changing its shading area continuously from its center area 7 toward its circumferential area 8, is placed in such a manner that the rotary disk 4 may rotate freely and the distance to the lens 2 can be changed. After being exposed to the light, the sensitive material 14 is taken out from the contact printer 12, and then developed to produce a graded type shadow mask pattern. Therefore, the grading can be made freely at the position of the rotary disk 4 and it can be easily produced with high accuracy.

Title: Memory cell
Inventor: ASAHINA KATSUSHI
IPC: G11C11/41
Filed: 1990-01-25
Abstract: PURPOSE:To increase read-out speed, and simultaneously, to prevent the storage data of a memory cell from varying according to the state of a read-only data line by driving the read-only data line by providing a bipolar CMOS buffer. CONSTITUTION:When a word line 1 is selected while the node A of the memory cell is H and the node B is L and so on, access transistors (TR) 15, 16 are turned ON, and the TR 14 is turned OFF, and the bases of the TRs 11, 12 to constitute the bipolar CMOS buffer become supply voltage VCC and earthing voltage respectively. Thus, the read-only line 4 is connected to emitter follower output by the TR 11 through the TR 15, and the line 4 is charged into H. Similarly to the case the node A is L, the read-out speed can be increased by driving the line by using a bipolar TR, and simultaneously, the storage data of the memory cell never varies according to the state of the read-only line.

Title: Structure of solder bump
Inventor: YOSHIHISA KAZUSHI
IPC: H01L21/321
Filed: 1990-01-26
Abstract: PURPOSE:To prevent a crack from being generated in a solder bump by a method wherein a conductive layer consisting of a material, which has a melting point higher than that of solder and has a Young's modulus smaller than that of the solder, is formed on a pad holding prescribed metal layers between the conductive layer and the pad and a bump-shaped solder is formed on the conductive layer. CONSTITUTION:An electrode formed on the surface of a mounting substrate is heated to 200 deg.C or thereabouts in a state that the top part of a solder bump 6 is adhered closely to the electrode. Here, the melting point of an eutectic solder is 190 deg.C, while the melting point of an Sn layer containing 2wt.% of Pb, which is used as a conductive layer, is 322 deg.C. Accordingly, a bump-shaped eutectic solder only, which is formed on the conductive layer, is dissolved by the heating of 200 deg.C or thereabouts and a pad 2 is bonded to the electrode on the mounting substrate. Accordingly, the conductive layer 5 is left intact without being dissolved at the time of this reflow and the height of the bump at the time of the reflow can be made even. The Young's modulus of the Sn layer is 1.83X10<11>dyn/cm<2> and is lower than the Young's modulus of 3.0X10<11>dyn/cm<2> of the eutectic solder. Accordingly, even if a transverse stress acts on the bump part, the stress is absorbed and a crack or the like is inhibited from being generated.

Title: Combination weighing method
Inventor: OSHIMA YASUSHI
IPC: G01G19/387
Filed: 1986-01-28
Abstract: PURPOSE:To simplify the constitution of a weighing apparatus and to reduce cost, by performing combination operation on the basis of the memory value of the memory means provided corresponding to each sump hopper. CONSTITUTION:When an article to be weighed is supplied to a receiving tray from a bucket conveyer by a control part, the article to be weighed is sent onto a mount tray by the rotation of a drum. At this time, a weighing apparatus emits a weighing signal which is, in turn, held to a hold circuit 56a. In the same way, the weighing signal of the next article to be weighed is held to a hold circuit 56b to finish the charging of the article to be weighed to a sump hopper 14. When weighing signals are stored in all of hold circuits 56a-56h, a combination generator 60 is operated to generate combination order and, according to this order, the difference between the sum of weighing signals and the stored value of a reference wt. memory circuit 66 is calculated successively by an adder/subtractor circuit 64. Next, combinations at this time are stored in a combination memory device 78 through upper and lower limit comparing circuits 68, 72. The memory device 78 allows the opening and closing gate 40 of the sump. hopper to open on the basis of the memory value thereof and erases the memory values of the hold circuits 56a-56h to receive the article to be weighed of the sump. hopper in a gathering hopper.

CONSTITUTION:A photodiode chip 1 is provided with a structure which treats a photocurrent as ineffective, where the photocurrent is generated by light impinging on a region outside a PN junction which serves as a photodetective region, and a cheap spherical lens is used as an lens optical system interposed between the chip 1 and an optical fiber 6, and light emitted from the optical fiber 6 is made to impinge on the photodiode chip 1. The optical fiber 6 is inserted into a housing 8 through a ferrule 7, and the light emitting end face of the optical fiber 6 and the light receiving face of the photodiode 1 are made to confront each other through the spherical lens interposed between them. An expensive lens such as a SELFOC lens or the like can be dispensed with, so that a photodetective device of this design can be obtained at a low cost.

Title: Thin film transistor and its manufacture
Inventor: TANABE HIROSHI
IPC: G02F1/1368
Filed: 1992-02-04
Abstract: PURPOSE:To prevent a substrate from melting and being damaged and impurity elements from dispersing by providing a shielding layer in the upper part and under the active layer of a substrate. CONSTITUTION:A base layer 102 consisting of SiO2, a laser shielding layer 103 consisting of an amorphous Si and an insulating preventive layer 104 made of SiNx are formed in sequence on a supporting base body 101 made of a barium borosilicate glass. On top of them, source drain layers made of MoSi105 and n<+>poly-Si106, respectively, and a channel forming active layer made of poly-Si107 irradiated with a laser beam are formed. Laser-irradiation at the time of active layer formation is performed after active layer deposition and before patterning. After that, a gate insulating layer 108 and a gate electrode 109 are formed to form a thin film transistor. So, the laser beam which goes through a to-be- annealed layer is absorbed or reflected on the shielding layer, never reaching a substrate to serve as the supporting base body, or weakened before reaching. As a result, the substrate is never directly heated by the laser beam.
