Title: Method and apparatus for inspecting surface state
Inventor: MITOME NORIYUKI
IPC: G01N21/956
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce possibility of unnecessary cleaning and overlooking a foreign matter, by setting information of a foreign matter signal obtained by inspecting a reticle in the state that usability is confirmed by a test exposure as a referring state, and then processing the signal by using the information, thereby rationally setting a rank of the matter in the shape corresponding to properties of the actual matter. SOLUTION: In the state that a reticle 1 is once confirmed to be usable, an output of a foreign matter 10 regarding the reticle 1 and coordinate information are already known. Accordingly, when a foreign matter is then inspected, only a foreign matter increased according to the information of the foreign matter inspection at the time of confirming usability is displayed. In the case of judging the increase in the matter 10, a test exposure is executed before a main exposure. And, whether there is a problem in manufacture of an element or not is judged. If there is the problem, a base plate is sent to cleaning. Meanwhile, if there is not a problem, the main exposure is conducted. Since the data comparing method with the previous time can correspond to special circumstances of the individual reticles 1, it is a general and effective method.

Title: Method and device for controlling pressure in packing liquid tank
Inventor: TSUKANO KENICHI
IPC: B67C3/12
Filed: 1991-09-12
Abstract: PURPOSE:To obtain an efficient work in which the quality of a product is not degraded even at a time of operation stop, and restart of operation is possible without any special step, by a method wherein, when non-operation state continues for more than a prescribed time period, pressure within a space above the surface of packing liquid is decreased to a prescribed value which is lower than that at a time of normal operation. CONSTITUTION:While pressure in a space 4 above the surface of packing liquid 3 in a packing liquid tank 1 is kept at a prescribed value, the packing liquid 3 is successively packed in each container 2. If non-operation state continues for more than a prescribed time period for some reason, a sensor detects out this, and accordingly, a control system is changed over to a controller 13 side. By this, the pressure in the space 4 can be controlled at a prescribed value which is lower than that at a time of normal operation. Thus, a balanced state can be kept at a target disolving degree. Therefore, even if the non-operation state continues, the target disolving degree can be kept, which prevents extra volume of gas from disolving, whereby a desired quality can be maintained.

Title: Manufacture of cable for audio
Inventor: KUROSAKA AKITO
IPC: H01B13/00
Filed: 1988-10-19
Abstract: PURPOSE:To enable an audio cable of excellent sound quality to be manufac tured stably by using high purity copper of 99.999wt.% or more for starting material, and applying ultrasonic cleaning in an organic solvent after extension or contraction processing, and annealing it in a specific extent of vacuum. CONSTITUTION:After extending line material consisting of high purity copper of 99.999wt.% in purity up to final line diameter, the line material after exten sion processing is cleaned by ultrasonic in organic solvent. In this case, as organic solvent to be used in ultrasonic cleaning there is trichloro ethane or fluorocarbon. Next, this baking treatment is done under the atmosphere above 200 deg.C at a vacuum degree of 10<-3>Torr for pressure so as to prevent impurity from penetrating into line material during anneal treatment. In this case, if heating temperature at anneal treatment is below 200 deg.C, recrystallization of the line material becomes insufficient and sound quality deteriorates. Hereby, a cable for audio with which excellent sound quality can be obtained stably at all times is obtained.
