Abstract: PURPOSE:To prevent the fluctuation of signals such as constant potential signals, by providing a plurality of bonding pads having the same functions on a semiconductor pellet, positioning the pads in the vicinities of the mutually facing sides of the semiconductor pellet, and electrically connecting the pads in the package, without especially increasing the width of a wiring. CONSTITUTION:Bonding pads 5 and 5' having the same functions are provided on a semiconductor pellet 2. The bonding pads 5 and 5' having the same function are positioned in the vicinities of mutually facing sides of a semiconductor pellet 2. Conductor parts 3 and 3' of a package 1, which are connected to the bonding pads 5 and 5' having the same function, are electrically connected in the package 1. Since the two conductor parts 3 and 3' at the grounding potential are provided in the package, the bonding pads 5 and 5' can be provided in the vicinities of the mutually facing sides. Thus the fluctuation of the grounding potential can be suppressed without especially increasing the width of an aluminum wiring 7 provided on the pellet.

Filed: 1988-02-26
Abstract: PURPOSE:To improve both undislocated crystallinity of single crystal to be produced and productivity by utilizing the state value of load wherein the conditions of a melting part are most sufficiently shown, namely, load fluctuation value and controlling growth of single crystal in a high-frequency induction heating FZ method. CONSTITUTION:Load fluctuation value is shown by the distance of a heating coil and a raw material rod and the distance of the heating coil and single crystal in a high-frequency induction heating FZ method. When it is deviated from the preset value, feed of crystal or the output of an oscillator is controlled in accordance with the degree thereof. For example, when the load fluctuation value consists of load constant Ft and load resistance force Rout, the constant Ft is shown by Rmelt/Lmelt in the case of defining the resistance of a melting part as Rmelt and defining induct ance as Lmelt. Then when the constant Ft is deviated from the preset value, feed of the raw material rod or single crystal is mainly controlled. When the load resistance Rout is deviated from the preset value, the output of the oscillator is controlled and thereby growth of single crystal is performed.

Abstract: PURPOSE:To perform effective form adjustment of sulfide and produce a steel of superior resistance characteristic to induced hydrogen embrittlement in particular by adding Ca dividedly in two stages to a ladle in which O and S are melted respectively at less than prescribed contents and an intermediate vessel from the ladle to a mold. CONSTITUTION:First Ca or Ca alloy is added under stirring at 0.1-0.4kg per ton molten steel into the molten steel in a ladle having beforehand been controlled to low concentrations of <=0.002% S and <=0.003% O, respectively, through desulfurizing and deoxidizing treatments. Even after the addition, the molten steel is stireed for a few minutes in succession, to float and separate the formed Ca type inclusions (e.g.; CaO), after which the molten steel is poured into an intermediate vessel from the ladle into a mold. Next, the amount of Ca shown by the formula is added according to the S concn. in the molten steel and the addition amount of Ca in the ladle into the intermediate vessel having been sufficiently lowered of the concn. of the atmosphere oxygen. As a result, the sulfide is perfectly form-controlled over the entire length of the continuously cast slab to prevent the deposition of MnS and the steel plate of good cleanliness and high HIC resistance performance is obtained.

Abstract: PURPOSE:To control a layer thickness of adhering separation film particles precisely by having a suspension liquid of separation film particles, which is to be brought into contact with a porous substrate, pressurized in a vertical direction to the contact face and flowed in a parallel direction to the contact face at a constant velocity. CONSTITUTION:Sintered alumina, etc., is used as a porous substrate and a suspension liquid of separation film particles such as fine alumina particles is used. The suspension liquid S in a suspension liquid tank 1 is sent to a film deposition section 6 at a high pressure through a circulation line L1 and returned to the tank 1 after passing through a hollow cylinder of a pipe-shaped porous substrate FS. A pressure of the suspension liquid flowing through the substrate FS is controlled to a prescribed pressure by using a pressure gauge 4 with a contact point and a pressure control valve 8. The suspension liquid in excess of that sent to the film formation section 6 is returned to the tank 1 through a bypass L2, while a flow rate of supply to the film deposition section 6 is kept constant at a prescribed value by controlling the flow rate through bypass L2 with a needle valve 10. After forming an adhering particle layer of a prescribed thickness, the substrate is taken out, dried and calcined so that a filtration member is produced.

Abstract: PURPOSE: To instantaneously complete the authentication after the paging by performing simultaneously these authentication and paging, to release the radio resources, and to attain the effective management of the radio resources. CONSTITUTION: In a paging state of a mobile terminal 3, a paging device 11 sends the random numbers of a random number generation device 13 to the terminal 3 together with a paging signal.

Then the device 31 adds the arithmetic result into paging answer signal to send them to a communication network 1 and extracts the authentication arithmetic result. At the same time, the device 11 sends the authentication information obtained from a terminal information storage 17 to an authentication arithmetic unit 19 together with the random number via a terminal information retrieval device 15 to obtain again the authentication arithmetic result.  This arithmetic result is compared with the extracted authentication arithmetic result for decision of the correctness of the terminal 3. Thereby, the reserved radio resources can be instantaneously released after the paging and before the transmission/reception of various signals when a wrong mobile terminal receives an incoming call.

SOLUTION: In the multizone air conditioner comprising indoor heat exchangers 8, 13, indoor temperature sensors 9, 14 and tube temperature sensors 10, 15 in indoor units 7, 12 of A and B chambers, an indoor temperature is detected at the time of starting a cooling operation. A difference between a tube temperature after a predetermined time is elapsed and the indoor temperature at the time of starting an operation is indicated by ▵T. Then, operating ability of a compressor 2 is judged according to a set temperature and the indoor temperature. A target value of the ▵T after a predetermined time is elapsed is corrected by the judged ability of the compressor 2. If the ▵T is lowered to the target value, solenoid valves 5, 6 are judged to be normal.  If the ▵T is not lowered to the target value, the valves 5, 6 are judged to be abnormal, and an alarm is displayed to notify a user.
