Title: Production of alpha-sialon sintered compact
Inventor: HASE TEIZO
IPC: C04B35/599
Filed: 1990-01-26
Abstract: PURPOSE:To obtain alpha-sialon enhanced in high-temperature strength and toughness by adding ultrafine silicon carbide powder to alpha-sialon powder and forming the mixture and burning the formed article. CONSTITUTION:5-35 pts.wt. silicon carbide powder having <=0.1mu grain size is added to 100 pts.wt. alpha-sialon powder and the mixture is formed and burned provide the objective sintered compact. Grain size of alpha-sialon powder used is preferably about <=0.6mu in average. A starting raw material consisting of alpha-sialon powder and SiC powder is formed and then burned under ordinary pressure, preferably in nitrogen atmosphere at 1700-1800 deg.C. According to the above-mentioned production method, dense alpha-sialon sintered compact can be obtained in ordinary-pressure sintering by adding ultrafine-grain SiC to '-sialon powder. Presence of the ultrafine-grain Si in alpha-sialon prevents a movement by slipping of grain boundaries and movement by deformation of grains and lowers creep rate and improves high-temperature strength and toughness.

Title: Link capacity assigning method in network design
Inventor: NISHIDA TAKESHI
Filed: 1988-01-25
Abstract: PURPOSE:To guarantee the service quality by defining the state space of a network with respect to a link fault and obtaining all link capacities other than a faulty link so that the average packet transmission delay is a predetermined threshold value or below with respect to each state in the relevant state space, that is, the faulty pattern of each link. CONSTITUTION:The network state (i) is represented as Pi and the state P0 represents no fault occurrence. When the processing is finished, whether or not the networks are linkes is checked in the block 101, and in the case of not linking, the next state is checked. In the case of linking, the capacity is assigned so that the average packet transmission delay is in a predetermined threshold value or below in the network state and the network cost is minimized. When it is discriminated that the link check and capacity assignment are implemented in all states in the block 104, the capacity C(i, j) obtained at each state is weighted by a prescribed value aij with the state production probability as the capacity Cj of the link (i) in the initial design in the block 105 to use the weighted average in all the state discriminated to be the linked state.

Abstract: PURPOSE:To automatize the initialization of time information of a system timer and the update of this information in the on-line control, by receiving radio broadcasting waves in a time counting device to separate and detect a time casting signal and outputting automatically corrected digital time information. CONSTITUTION:Radio waves of a broadcast station 6 are received in a time counting device 5 of a computer system 10, and time signal is separated and detected to generate and output corrected digital time information. Consequently, when a seizing signal is given to a CPU 2, the initializing program of the on-line control is executed, and digital time information automatically corrected with the time signal is inputted from the time counting device 5 and is set to a system timer. In the on-line control, since the time casting signal detected by the time counting device 5 is outputted to the CPU 2 as an interrupt signal, the system timer is updated at a prescribed period.

Abstract: PURPOSE:To allow heat generated by a semiconductor chip to effectively dissipate, by constructing the chip such that a lead is bent within resin and that the section in which the semiconductor chip is fitted is located on or near the surface of the resin. CONSTITUTION:For the purpose of improvement of the heat-dissipating effect of a chip semiconductor device, a semiconductor chip 2' is bonded to a lead 1', an electrode of the semiconductor chip 2' is connected to a lead 4' with a metallic small-gage wire 3', and such a structure is sealed with resin 5'. The lead 1' to which the semiconductor chip 2' is bonded is bent within the resin 5' and the rear face of the section in which the semiconductor chip 2' is bonded is exposed from the resin 5'. Alternatively, a slight thickness of resin 5' may exist on a lead 2'' supporting the semiconductor chip 2', on the surface thereof where the chip 2' is not carried. This resin may be either covered on that surface at the same time with the sealing of the resin, or applied thereon after the same. The resin is preferably formed into a thickness from about 20mum to 200mum. If it is too thick, the heat-dissipating effect will be deteriorated, while if it is too thin, the mechanical strength will become difficult to hold and the insulation effect will be deteriorated.

Title: Resistance measuring circuit
Inventor: MASAKI TAKESHI
IPC: G01R27/14
Filed: 1986-01-28
Abstract: PURPOSE:To calculate the accurate resistance value of a buffer amplifier 11 by providing an integrator and a switch which switches the input and output sides of an integration circuit and controls its integrating operation time. CONSTITUTION:This circuit consists of a buffer amplifier 11, the integrator 12, its switching controller 13, an A/D converter 14, a data processor 15, etc., and a constant DC current is supplied to the resistance body 5 to be measured from a constant current source 6. When the current is supplied to the resistance body 5, a specific voltage is developed between both terminals of the resistance body. When an induced noise from, for example, an AC power source is superposed upon said voltage, the voltage across the resistance body 5 is passed through the amplifier 11 and integrated 12, so that the integrated voltage appears across a capacitor. At this time, when the integration time is set to one cycle period of the induced noise frequency, the noise component is canceled even if the induced noise is superposed. Therefore, the integral voltage obtained through the integrator 12 contains no induced noise and sampling is performed only once to calculate the accurate resistance value from digital conversion data.
