Title: Method of lithography and lithography system using such method
Inventor: IMAI YUJI
IPC: G03F9/00
Filed: 1988-11-02
Abstract: PURPOSE:To detect an alignment mark by covering a substrate with a resist layer, detecting the alignment mark before a solvent in the resist layer is evaporated, and suppressing the change in thicknesses of the resist film in the vicinity of the alignment mask to a very small value. CONSTITUTION:After the application of resist, the surface of a resist layer PR in the vicinities of edges E1 and E2 of a protruding mark pattern MA on a wafer W is very flat. After prebaking, however, the flatness is lost in the vicinities of the edges E1 and E2, and steps T1 and T2 are generated. Therefore a prebake step (evaporation of solvent by heating of the substrate) after the resist application is omitted, and an alignment mark on the substrate can be detected. In this constitution, a first mode and a second mode which performs substrate heating and detects the pattern on the substrate as in the conventional method can be alternatively selected. Thus, the mark can be detected under the state wherein the surface of the resist layer is made flat as much as possible.

Abstract: PURPOSE:To find the operation of a safety device by warning and lamp indication by linking one end of a movable piece to the safety device, and operating a switch outside of a capacitor with bellows provided at a part of a case based on the movement of the movable piece. CONSTITUTION:When decomposed gas is generated due to an internal fault in a capacitor and the like and the inner pressure in a case is increased, a lead plate 42 of a safety device 4 is broken by the deforming force of the case. Therefore, the safety device 4 is divided into two parts, and the space between them is expanded. A linking rod 43 is pulled out of the ring part of a movable piece 6. The linkage between the movable piece 6 and the safety device 4 is disengaged. The movable piece 6 is moved by the returning force of a spring 5. A top protruding part 61 of the movable piece 6 elongates bellows 22 provided in the case. An actuating lever for a switch 23 which is attached in the close proximity with the bellows outside the case is pushed up. Thus the switch can be operated. In this way, the capacitor can be automatically released from a power source, lamp indication is performed and warning can be issued. This is convenient for maintenance.

Title: Bubble file memory device
Inventor: MATSUI NAOKI
IPC: G11C11/14
Filed: 1988-11-08
Abstract: PURPOSE:To reduce the starting time of a whole system by processing the actuation of the memory device at the time of a low and high abnormal temperatures so that the abnormal temperatures can be canceled in a short time. CONSTITUTION:A temperature detecting means 61 detects the temperature of a bubble cassette section and an abnormal temperature state discriminating means 62 discriminates the abnormal temperature state of the bubble cassette section from the temperature detected by the means 61. When the means 62 discriminates that the cassette section is in a low abnormal temperature state, a low abnormal temperature processing means 63 selects all circuits from the cassette section and causes each element of the selected circuits to produce heat so as to raise the temperature. When a high abnormal temperature state is discriminated, a high abnormal temperature processing means 64 sets all circuits in the high temperature state in the cassette section to standby states so as to suppress the heat production from each element of the circuits. Therefore, this bubble cassette memory device can be actuated in a short time when the section is in a low and high abnormal temperature states.
