Abstract: PURPOSE:To enhance durability and precision of a pattern by forming a carbon film pattern on a transparent base plate. CONSTITUTION:The amorphous carbon film 12 is attached to the quartz glass plate 1, and the film 12 is coated with a resist film 13. This film 13 may be formed by the sputtering method, or, for example, the vapor phase growth method using a vapor phase growth device.

Title: Time out detection system
Inventor: IIDA SHOZO
IPC: G06F11/30
Filed: 1990-02-14
Abstract: PURPOSE:To easily discriminate the cause of fault by detecting the time out at the time when one data transfer is not terminated within a prescribed time or data transfer is not started within a prescribed time after reception of a new start request from a physical channel. CONSTITUTION:A timer 102 is started when an interface signal control part 101 starts data transfers from a physical channel, and the timer 102 expires if the data sequence takes a time longer than normal. When a microprogram control part 105 reads out a logical channel number to request selection of a seek address to the physical channel, one of timers 106A to 106N which corresponds to this channel is started. If transfer is repeatedly retried at this time, the timer corresponding to the logical channel waiting for seek or search completion detects the time out. Thus, extension of the data transfer time due to disturbance of the data sequence or frequent occurrence of retrying is discriminated as the cause of time out.

Title: Mold for continuous casting
Inventor: UCHINO KAORU
IPC: B22D11/04
Filed: 1989-02-14
Abstract: PURPOSE:To suppress the development of surface defect at edge parts in a cast slab by arranging rapid cool preventing member having smooth curving face at casting wall of the range, in which at least initial solidified shell is formed, in corner part of a mold body having rectangular shape in cross section of the casting range. CONSTITUTION:By opening a tundish nozzle, molten steel is poured into the mold 10. By being brought into contact with the casting wall members 12, 14, the solidified shell is formed. The molten steel 5 is forcedly cooled with the casting wall members 12, 14 in long sides and short sides, but cooling effect of the members 12, 14 is relieved with the rapid cool preventing member 16 at the corner parts in the mold. In this way, excess cooling of the molten steel at the corner parts is eliminated, and the initial solidified shell 6 is grown at good balance even in the corner parts, and even in the case bulging develops, overlap of the thin solidified shells does not occur. As the rapid cool preventing member, heat resistant ceramic or metal may be used, but particularly copper or copper alloy is desirable. By this method, maintenance work, such as surface scarfing in the following stage, is scarcely necessary and also improvement of yield of a cast slab can be obtd.

Title: Oscillating actuator
Inventor: HAYASHI ATSUHIKO
IPC: F15B15/06
Filed: 1983-03-04
Abstract: PURPOSE:To thoroughly avoid problems in accuracy and fluctuation in moving speed due to backlash and abrasion of an engaging member by wrapping two transmission elements in the opposite direction to each other round a shaft, the other ends of which are couled to actuators, respectively. CONSTITUTION:A shaft 16 is provided with two fixing tongue pieces 17, 18 peripherally and longitudinally spaced from each other.
