IPC: G06F13/00
Filed: 1993-06-01
Abstract: PURPOSE:To recognize the state (bus state) of an SCSI bus before the abnormality of the SCSI bus is detected. CONSTITUTION:Under the control of an SCSI bus trace control circuit 15, data on an SCSI bus 12 are written in an SCSI bus trace memory part 18 and updated as SCSI bus data. When it is judged by an SCSI controller 13 any abnormality is generated at the SCSI bus 12, a stop signal is sent from an abnormality detection circuit 19 to the SCSI bus trace control circuit. Thus, the SCSI bus trace control circuit stops the update processing. Then, the DMA transfer of the SCSI bus from the SCSI bus trace memory part 18 to a host bus 14 is performed by a DMA controller 20.

Title: Method and circuit for generating time change signal
Inventor: DEBUITSUDO EMU TEIRAA
IPC: H03K4/02
Filed: 1985-06-14
Abstract: A method and a circuit for approximating a continuous range of signals having sinusoidal waveforms with signals having trapezoidal waveforms, and for generating a continuous range of frequencies around a given center frequency. The circuit forms trepazoidal waveforms by a computational technique. A periodic triangular waveform is first formed by repetitiously adding and substracting an amplitude increment at a succession of time intervals. The time intervals can be large, thereby allowing a low sampling frequency. The peaks of the triangular waveform are truncated to form the trapezoidal waveform. The circuit can be easily implemented within a standard arithmetic logic unit (ALU) structure.

Abstract: PURPOSE:To make it possible to obtain a high contrast resist pattern by a method wherein infrared rays are made to irradiate in a non-oxygen atmosphere after ultraviolet rays have been projected, and ultraviolet rays are projected while resist surface is being heated. CONSTITUTION:A photoresist film 4 is applied on the surface of a semiconductor substrate 1, and the film is selectively irradiated with ultraviolet rays 4 in accordance with the pattern on the mask 3. The ultraviolet-ray exposed part and the non-exposed part of the resist film 2 are simultaneously surface-heated by infrared rays 5 to 100 to 130 deg.C, then ultraviolet rays are projected on the whole surface and the ultraviolet- ray exposed part 2a of the resist film 2 is removed. To be more precise, by the irradiation of ultraviolet rays while the surface of the photoresist film 2 is being heated by infrared rays 5 in a non-oxygen atmosphere, an esterification reaction is generated between the resist of the resist film 2 and a photosensitizer, the solution speed against a developing solution decreases as going to the upper layer part of the resist, and the angle between the side wall of the pattern and a substrate after developing becomes 90 deg. or thereabout. As a result, a resist pattern of excellent form, having small variation in the pattern dimensions on the upper and the lower part of the stepping, can be obtained.

Accordingly bellows 19 are compressed with a slight movement of the push piece 21, and even if the internal air flows out through vents 32..., it is passed through the vapor relief passage 10 from the flow-in port 11 to be released to the atmosphere from vapor holes 38....  Therefore, the hot water in a tank 3 will never be pressurized, and there is no risk that the hot water spouts out of the pour-out hole 44 undeliverately to caused person to have a burn.
