Title: Evaluation of semiconductor element
Inventor: YAMASHITA HIROSHI
IPC: G01N21/956
Filed: 1990-06-25
Abstract: PURPOSE:To make it possible to observe a sufficiently contrasted image in an observation using not only a scanning type electron microscope but also an optical microscope by a method wherein a conductor wiring is removed using an etching liquid, whose etching rate to a semiconductor substrate and the conductor wiring is larger than its etching rate to an interlayer insulating film, or the like. CONSTITUTION:A conductor wiring 4 is etched away using an etching liquid, whose etching rate to a semiconductor substrate 1 and the wiring 4 formed on the main surface of the substrate 1 is larger than its etching rate to an interlayer insulating film 3 provided between the substrate 1 and the wiring 4, or etching gas. For example, a sealing resin and a semiconductor element, from which a surface protective film is removed, are dipped in a potassium hydroxide aqueous solution heated to 80 deg.C and a polysilicide film 4 is removed. Then, when the surface is observed using an optical microscope or a scanning type electron microscope, a quadrangular pyramid formed by selectively etching a silicon substrate 1 can be observed in a nondefective opening part 5a, while the substarte 1 is not etched and a quadrangular pyramid is not observed in a defective opening part 5b because one part of an interlayer insulating film 3 is left on the bottom of the opening part 5b in the defective opening part 5b.

Title: Low pressure rare gas discharge lamp
Inventor: NISHIKATSU TAKEO
IPC: H01J17/20
Filed: 1981-10-20
Abstract: PURPOSE:To obtain a low pressure neon discharge lamp that can mainly obtain emission of neon by containing a small amount of krypton. CONSTITUTION:In a discharge container that seals the mixed gas of neon and krypton, supposing that the sealing pressure of the mixed gas is P (Torr) and the krypton mixing ratio is A (%), a relationship of A<=8P<-2>(%) is satisfied. As a result, since the mixed gas of krypton and neon is used, the discharge start voltage can be reduced by Penning's effect. For example, for the pressure of 5 Torr, while the discharge start voltage of a lamp that seals single body of neon is approximately 135 V, that of a lamp krypton mixing ratio of 0.1% is reduced to approximately 110V.

Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a change on the controller side when a change of a function of equipment on the target side occurs. SOLUTION: At a step S1, a control part 13 inside a tuner 2 reads subunit identifier descriptor of a DVCR 3 by way of an IEEE 1394 bus 4 and proceeds to a step S2. At the step S2, the control part 13 decides whether the DVCR 3 is a new type AV equipment or not. When the DVCR 3 is judged to be an old type AV equipment, processing is finished. When the DVCR 3 is judged to be a new type equipment, a step S3 is proceeded to and the control part 13 transmits a notify command to the DVCR 3. At a step S4, the control part 13 receives an INTERIM response of reception confirmation returned from the DVCR 3. At a step S5, the control part 13 judges whether or not a changed response for indicating that a change of a function occurs is received.  When it is judged that the changed response is not received, the step S5 is returned to; when it is judged the CHANGED response is received, the step S1 is returned to and the following processing is repeated.
