Title: Mounting method of resin-sealed semiconductor device
Inventor: IKOU KAZUO
IPC: H01L23/32
Filed: 1983-06-09
Abstract: PURPOSE:To prevent the decrease in the moisture resistant reliability after solder dipping by containing 0.1wt% or lower of water content of sealing resin, and 0.1vol% or higher of volume of a semiconductor element in the resin sealer. CONSTITUTION:The external leads of a semiconductor device 3 sealed with epoxy resin containing 65-80wt% of silica powder are matched to the circuit pattern terminal 2 of a printed board 1, and temporarily mounted at 6. Then, the substrate surface 11 of the device 3 at the mounting side is dipped in a solder path. In this case, the water content of sealing resin is set 0.1wt% or lower, and the occupying volume of a semiconductor element in the all volume of the sealer is set to a range of 0.1-25vol%. According to structure, even if a resin-sealed semiconductor can be mounted on the printed board by solder dipping normally at 260-350 deg.C for 2-15sec., the moisture resistant reliability of the device is not lost.

Title: Method and device for sieving sintering ore
Inventor: KATO TOMONORI
IPC: B07B1/46
Filed: 1988-04-28
Abstract: PURPOSE:To efficiently sieve sintering ore to small grain sizes and to improve the yield of sintering by constituting the device in such a manner that the sintering ore is allowed to flow down in twofold sieve regions under the conditions of closing or limiting the apertures of said regions to stratify the grain sizes of the ore and is thereafter subjected to the sieving in ordinary sieve regions. CONSTITUTION:The sieving equipment alternately formed with the twofold sieve regions A and the ordinary sieve regions B is prepd. and the apertures in the regions a are substantially closed or limited to limit or stop the sieving action in the regions a and to stratify the sintering ore flowing in these parts. Namely, the fine grains of the sintering ore flowing in said parts are fractionated to the lower layer and the coarse grains to the upper layer. The sintering ore is allowed to flow down in the ordinary sieve regions B after such stratification, by which the efficiency of classifying the fine grains is enhanced and the probability of incorporating the coarse grains into the minus sieve is extremely lowered. The hindrance of the sieving by the down flow of the coarse grain components is thus prevented and the effective sieving is executed even under the conditions of a small sieve area.

Title: Hydraulic driving gear for construction machine
Inventor: YASUDA TOMOHIKO
IPC: F15B11/00
Filed: 1988-04-28
Abstract: PURPOSE:To permit work of a heavy load to be performed preventing an internal combustion engine from overheating by providing an oil hydraulic actuator which actuates an operating oil-supplying oil hydraulic pump by a delivery flow amount not more than the maximum value in accordance with a temperature sensor output signal. CONSTITUTION:During work of excavation or the like by a hydraulic cylinder 13, when a temperature of cooling water increases to a preset value or more, a relay 15 is excited in its coil by a flow of current in a temperature sensor 26, and a relay 25 closes its contact, moving a spool in a solenoid valve 24. In this way, a hydraulic cylinder 21, introducing delivery oil from an oil hydraulic pump 22, moves a rod actuating a mechanism 12A, and a load for an engine 11 is decreased by decreasing a delivery flow amount of an oil hydraulic pump 12 to a value not more than the maximum delivery flow amount. While, when a temperature of cooling water decreases from the preset value, the solenoid valve 24 closes, and opening a relief valve 23, the delivery oil from the oil hydraulic pump 22 is recirculated into an oil tank. Thus preventing the engine 11 from overheating, heavy load excavating work can be performed.

Abstract: PURPOSE:To drive an ink jet printer at a voltage below a given power source voltage by a method in which impedance in the flow path, the thickness of piezo-electric element, and the viscosity of ink are chosen below given values and the area of the piezo-electric element and the impedance ratio of the flow path are chosen above given values in an ink-on-demand type ink jet head. CONSTITUTION:An ink jet head is made up of an osicillation system consisting of a pressure chamber 1, a supplying part 2, a nozzle part 3, a piezo-electric element 11 and an oscillation plate 12. Also, the electric equivalent circuit of the head is represented by inductance (m), acoustic capacity C, and acoustic resistance (r). In the equivalent circuit, if the pressure phi is made out as a step function, a damping oscillation results and the drive voltage V becomes V=(2phi<2>Co/ K<2>Cp)<1/2>. To minimize the drive voltage V, the impedance of the flow system, the thickness of piezo-electric element, and the viscosity of ink are chosen below given values, and also the area of the piezo-electric element and the impedance ratio of the supply and injection sides are chosen above given values.

Title: Liquid jet head
Inventor: FUKUCHI HIROMICHI
IPC: B41J2/055
Filed: 1980-07-30
Abstract: PURPOSE:To enable high speed typing by providing the channel part having the ink charging ports connected to the ink chamber to the two places of the parallel channel part with the jet nozzle and the squeeze channel part between the pressure chamber and the auxiliary pressure chamber. CONSTITUTION:Deflection of a flexible plate 17 induced by loading electric signal to the piezovibrators 19, 20 causes to increase inner pressure of the pressure chamber 11 and the auxiliary pressure chamber 14 and to inject the ink droplets from the jet nozzle part 10. At the same time the ink droplet 18 is going to flow back to the auxiliary pressure chamber 14 through the squeeze channel A3, but backflow is prevented opposing to inner pressure of the auxiliary pressure chamber 14 and is cancelled. Then high speed typing becomes possible by lessening the volume change of the pressure chamber 11 and distorsion of the piezovibrator. Also, the ink charging ports 12-1, 12-2 are prepared at the channel A2, A3, time necessary to charge ink can be shortened and it enables to make initial injection velocity constant.

IPC: H04J3/06
Filed: 1988-04-26
Abstract: PURPOSE:To make the circuit scale smaller by providing a synchronizing pattern generating section to a line setting common section so as to insert a synchronizing pattern as soon as a line designating plural input data transmission destinations is set. CONSTITUTION:A multiplex section 2 multiplexes plural input data in a line setting common section 1, a memory 3 replaces stored data based on a command from a line setting data generating section 4 and a demultiplex section converts the data into plural output data for the output. The synchronizing pattern generating section 6 generates a required synchronizing pattern for sending it to a transmission destination designating plural output data and inputs it to the memory 3 via the multiplex section 2 together with the plural input data. Then the synchronizing pattern is inserted to a time slot at the head of plural data simultaneously with the replacement of the plural data. Thus, one synchronizing pattern generating section is enough to be provided to the line setting common section 1 and the device is simplified and miniaturized.
