Title: Method of fabricating semiconductor device
Inventor: TAKADA CHIYUUICHI
IPC: H01L21/027
Filed: 1978-09-29
Abstract: PURPOSE: To improve the adherence of a seminconductor device and fabricate a precisely fine pattern on the semiconductor device by exposing a predetermined patter on a positive resist, then calcining the resist at 150°C or higher, and thereafter developing it.  
     CONSTITUTION: After positive resist is coated on a semicondutor substrate, the substrate is calcined at 95°C, exposed with light, calcined at 150°C or higher, and then developed. When the substrate is thus treated at high temperature, its gamma characteristics is improved, and when light illuminating energy is low, its dissolving speed is remarkably lowered. Thus, the peripheral edge of the pattern is formed sharply, unexposed portion of the peripheral edge of the pattern is feasibly formed larger than the desired size to thereby conveniently control the size of the pattern according to the exposure time. Since it can also improve the adherence of the semiconductor device by light temperature calcination, precisely fine pattern can be obtained.

Title: Data transfer method
Inventor: OHATA MASAO
IPC: G06F13/42
Filed: 1986-05-28
Abstract: PURPOSE:To increase the data transfer speed by eliminating the confirmation of a ready flag when data are sent to an I/O device from a CPU. CONSTITUTION:When a CPU5 transfers data to an I/O device 6, the transfer data S1 is delivered to a data register 7 and a data transfer signal S2 is simultaneously outputted through a strobe terminal ST. The signal S2 is supplied to an AND gate 8. In such case no ready signal S3 is outputted from a data register 7 of the device 6 as long as the register 7 is not possible yet to fetch data. Thus the gate 8 is closed and no data transfer signal S4 is supplied to the acknowledge terminal ACK of the CPU5, therefore the CPU5 is kept waiting as it is. In such a way, it is not needed to conform a ready flag in a data transfer mode, therefore the data transfer speed is substantially increased.

Title: Optical head
Inventor: SUZUKI YASUO
IPC: G11B7/12
Filed: 1988-05-18
Abstract: PURPOSE:To reduce the inclination of optical parts caused at the time of adhesion and temperature rise by providing a clearance groove at the corner part of an optical head main body, and chamfering the edge part of the optical parts to be built in the main body, and bonding them as keeping the corner part and the edge part in a non-contact state. CONSTITUTION:A slope 8c' is formed at the escaping part of adhesive B of the optical head main body 8, and abutting surfaces 8e', 8f' for a polarized light beam splitter 3 are cut. On the other hand, the edge part of the splitter 3 is chamfered so as not to come into contact with the abutting surface 8f'. At the time of the contact of the splitter 3, the main body 8 is in contact only with the surface 8e', and the inclination due to the running-on over the surface 8f' of the edge part of the splitter 3 is prevented. Besides, excessive adhesive B is dropped into the clearance groove 8a' by the surface 8c'. Accordingly, even if a burr is generated or the adhesive B expands at the time of the temperature rise, the splitter 3 never inclines, and low-cost and highly reliable adhesion can be realized.
