Title: Access system of cache preceding
Inventor: KOSUGE YASUHARU
IPC: G06F12/08
Filed: 1983-08-01
Abstract: PURPOSE:To prevent the deterioration of a system by limiting a block to be fixed on a cache to an area specified by an address in accessing and the address of preceding access. CONSTITUTION:Sequential access already accessed the copy of a block A in a main storage buffer 30, i.e. a block (a) in the cache 2 and is accessing the copy of a block B, i.e. a block (b).

Title: Ebullition cooling type semiconductor device
Inventor: ISHIDA SHIGEO
IPC: H01L23/427
Filed: 1981-09-09
Abstract: PURPOSE:To preliminarily prevent the trouble of semiconductor device through quick and safety detection of non-condensation gas mixed to a hermetically sealed vesel or a cooling vessel by comparing the temperatures in the divided hermetically sealed vessel. CONSTITUTION:The input signals 8 and 9 of signal conversion circuit show almost the same level in normal condition. Therefore a comparator 12 does not provide any output and accordingly trouble indication is not obtained. But the temperature within the sealed vessel in a cooling unit consisting of a non- condensation gas casing and heat sink shows an extreme temperature rise as compared with the temperature in the noraml hermetically sealed vessel. This is because the condensation performance of cooling unit is remarkably lowered due to mixture of non-condensation gas. Therefore the comparator 12 provides an input of the time setting unit when the input of the comparator is higher than the predetermined level and causes a trouble indicator 14 to operate only when the input of time setting unit continues for the specified period.

IPC: H01L23/28
Filed: 1994-06-23
Abstract: PURPOSE:To control the outflow of resin regardless of its viscosity by forming projecting sections 3t one side or both sides of a part of each inner lead on a first side of a semiconductor substrate which is a region located between the first side of the semiconductor and an edge of a device hole which faces the first side of the semiconductor substrate. CONSTITUTION:Projecting sections 4 are formed at one side or both sides of a part of each inner lead on a first side of a semiconductor element 2 which is a region located between the first side of the semiconductor element 2 and an edge of a device hole 1 which faces the first side of the semiconductor element 2. The shape of the projecting sections 4 which are provided in the inner leads 3 is such that an electric field may be prevented from concentrating on adjacent inner leads. For example, the projecting sections are formed in the inner leads which are arranged at a larger pitch. By this method, an unevenness of the thickness of sealing resin on the surfaces at the resin-applied side and at the rear side can be prevented without controlling a viscosity of the resin. Therefore, products which have an excellent crack resistance and moisture resistance can be manufactured with a better yield and the use of the resin can also be reduced.

Filed: 1986-06-18
Abstract: PURPOSE:To decrease defects and distortions on the boundary parts of crystal grains in a polycrystalline material to improve electrical characteristics of elements such as thin-film transistors, by radiating ultraviolet rays on a polycrystalline thin film and concurrently performing heater annealing and then moving a heater at a definite speed mutually to a substrate. CONSTITUTION:A polycrystalline thin film 12 is formed on a base substrate 11 by using a reduced-pressure vapor growth method, a plasma vapor growth method, various evaporation techniques, and so on. The substrate 11 is usually heated for this formation. Ultraviolet rays 4 are radiated on the polycrystalline thin film 12 part of the polycrystalline substrate 1 manufactured in this way. The ultraviolet rays 4 are effectively absorbed in the boundary parts of the crystal grains because of defects and various distortions existing there. Concurrently the irradiated parts are heated by using a strip heater 3,and then the heater 3 is moved at a speed of 0.1mm/sec-10mm/sec or so mutually to the polycrystalline thin-film substrate 1. Thus, granular-field defects and the like in polycrystal silicon are annealed uniformly over a large area, so that thin-film transistors manufactured in this way can be improved in electrical characteristics.
