Patent JP-H06196383-A (JP)
Title: Aligner
Inventor: UCHIDA NAOKI
IPC: H01L21/027
Filed: 1992-12-25
Abstract: PURPOSE:To correct an error in the magnification of a pattern transfer operation by controlling the temperature of an object to be transferred such as a glass substrate or the like. CONSTITUTION:When thermal expansion by an exposure operation and residual thermal expansion from a previous process exist, a pattern on a mask 3 is transferred onto a substrate 8 while an error is included. Peltier elements 11 which have been attached to the surface and/or the back of a substrate-holding stage 7, other temperature control means or the like are installed. Thereby, when the temperature of the substrate 8 is controlled, the substrate is maintained in a constant-temperature state or its temperature is changed, the magnification at which the pattern on the mask 3 is transferred to the substrate 8 can be corrected.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain an IC package, in which a resin-flow preventive dam for resin sealing is formed with high accuracy and whose flatness degree is ensured by a method, wherein a plurality of lands for external electrodes are formed to be an area array shape on the rear surface of a ceramic substrate and the resin-flow preventive dam which is made of a metal or a resin is bonded to the outer circumferential part of the ceramic substrate. SOLUTION: A resin-flow preventive dam 2 which is made of a metal or a resin and which is nearly square shape is bonded to the outer circumferential part of a ceramic substrate 1. Lands 4 for wire bonding are formed on the surface of the ceramic substrate 1, and lands 5 for solder balls are formed to be an area array shape on the rear surface of the ceramic substrate 1. Since the dam 2 is formed in the outer circumferential part of the ceramic substrate 1 at an IC package 10 in this manner, it is possible to prevent a resin from flowing out to the outside from the ceramic substrate 1, when a semiconductor chip which is mounted on the ceramic substrate is resin-sealed. In addition, since the dam 2 is made of a metal or the like, a micromachining operation which conforms to the shape of the outer circumferential part of the ceramic substrate 1 can be performed easily.

IPC: C22C37/10
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To improve the thermal fatigue resistance of the cylinder head by allowing it to contain respectively specified amounts of S and rare earth metals. SOLUTION: A cast iron material contains Cu, Cr and Mo and moreover contains, by weight, <=0.1% S and 0.015 to 0.3% rare earth metals. In this way, the crystallization of carbides contg. Cr and Mo is suppressed, and the entering of Cr and Mo into solid solution in a base structure is securely executed to improve the thermal fatigue resistance of the cast iron material. Moreover, by the incorporation of Cu, the crystallization of carbides is suppressed as well. Preferably, the content of Cu is controlled, by weight, to 0.3 to 1.2%, that of Cr to 0.1 to 0.6%, and that of Mo to 0.3 to 0.9%. Furthermore, when Ni is allowed to be contained instead of Cu, the formation of carbides can be suppressed similarly to the case of Cu, and, moreover, its corrosion resistance improves. The content of Ni is controlled to 0.3 to 1.2%.  As the rare earth metals, preferably, one or more kinds among Ce, La and Nd are contained.

IPC: G08B27/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To provide the effect of initial fire extinguishment by converting time difference from fire occurrence to announcing to the site arrival of fire vehicle through rear-time information transmission by transmitting information in real time from a station line through an exchange to a fire commander by an announciator by starting a sensor. SOLUTION: When a sensor 2 is started, station power is supplied, and an announciator 1 transmits fire information in real time from a station line 7 through an exchange 3 to a fire commander 5. Further, a computer station data base 4 detects a call originating number and a call originating place through the exchange 3 and displays them on a display 6 of fire commander 5. Since a PB signal for transmitting a real fire signal and the call originating place are displayed at the fire commander 5, the fire information and the site can be grasped and a dispatching command taking priority over backward communication can be provided.  Further, since a report from a telephone except for portable telephone to a number '119' (in Japan) automatically displays the call originating number and the call originating place at the fire commander 5, emergency rescue and disaster prevention against earthquake and damage caused by wind and water can be quickly dealt with as well.
