Title: Heat exchanger
Inventor: KIDO OSAO
IPC: F28F1/32
Filed: 1984-07-17
Abstract: PURPOSE:To disturb an air stream to increase a turbulence promoting effect and to reduce a stop region on the rear stream side of a thermal medium pipe to improve the heat transfer coefficient by providing cut-up pieces in a direction opposing the air stream on small-piece fins at the rear stream side from the thermal medium pipe with respect to tha air stream. CONSTITUTION:An air stream flows in the direction B between small-pieces fins 3, and a thermal medium flows within a thermal medium pipe 2. A heat exchange is carried out between the air stream and the thermal medium through the small-piece fins 3 and the thermal medium pipe 2. Upon this occasion, the small-piece fins 3 constitute a predetermined columnar pitch (b) and divided into a large number to obtain a bordery layer front edge effect. Further, by the cut-up pieces 4 applied to the small-piece fins 3, an air stream disturbed by the thermal medium pipe 2 is further greatly disturbed. Further, since the raised- slotled pieces 4 are formed by raising and slotling part of the steop region of the air stream produced ar the rear steram side thereof, the availble heat transfer area is not reduced. Moreover, an action of reducing the stop region of the air stream produced on the rear stream side of the thermal medium pipe 2 by the raised-slotted 4 is generated.

Filed: 1984-07-17
Abstract: PURPOSE:To make the replacement of a photomask unnecessary and to simplify an operation by reducing and projecting a main chip exposing pattern or a semiconductor integrated circuit device and at least one kind or more of other chip patterns, onto the same photomask material. CONSTITUTION:A main chip exposing pattern 212 of a semiconductor integrated circuit device and a pattern 213 containing a group of various decices, which is different from the main chip are constituted on a photomask 211 for a reduction projecting exposure device. When a wafer is exposed by using the photomask 211, as for an exposed part 222 of the main chip pattern on the wafer 221, an expanse of a blind of the reduction exposure device is set so that only the main chip pattern side (212) is exposed. As for a part 223 for exposing various device patterns, the expanse of the blind is set so that only the side of various device patterns is exposed by considering a positional offset of the wafer stage side caused by a difference of a pattern position on the photomask. In such a way, the photomask is positioned by only once, and the operation can be simplified.

Title: Treatment of registration mark
Inventor: SAEKI HIDEO
IPC: G03F7/16
Filed: 1981-09-19
Abstract: PURPOSE:To facilitate the detection of a registration mark and thus to improve the accuracy of pattern alignment by preventing the mark from being coated with a resist through the surface treatment of a mask portion using a fluorine- system surface active agent. CONSTITUTION:A 3-inch Si wafer with a registration cross mark from formed thereupon is set on a rotary coating apparatus, and a mark portion is coated with a 0.5% methanol solution of a fluorine-system surface active agent such as FLORARD FC-134 (made by Sumitomo-3M), which is then dried. While dropping onto the wafer an EB resists, OEBR-100 (made by Tokyo Oka Kogyo), the wafer is rotated at 1,000r.p.m. to form a 1.2mum-thickness resist film on it. However, the mark portion repels a resist solution because of the decrease of its surface energy, causing that portion to be left uncoated. After pre-baking at 80 deg.C, registration is made at an acceleration voltage of 10kV using an electron beam exposure apparatus, with the result that the mark detection is made with ease and the accuracy of exposed pattern alignment is satisfactory.

Abstract: PURPOSE:To make a notification when a transmission is not available due to the state of the other device by outputting a busy sound when a CED/busy sound detecting section does not detect the line connection signal sent back from a receiver after sending dials from a control section and detecting the busy sound transmitted from an exchange. CONSTITUTION:After dialing from a control section 4, a CED/busy sound detecting section 7 does not detect a line connection signal sent back from a receiver but detects the busy sound sent from an exchange, a control section 1 outputs the busy sound, sent from the exchange, from a monitor speaker 9, immediately notifying the communication of the other device to an operator who has finished a sending control by means of the busy sound. Accordingly, when the state of the other device inhibits the communication, the fact is notified smoothly so that a transmission original is prevented from being left on the device for a long time because an operator could not find it or the check message showing the transmission inhibition is prevented from being printed out wastefully.
