CONSTITUTION:The Fig (a) shows the state that a groove is provided by etching after a photoresist 9 is provided on an N type InP substrate 1. The Fig (b) shows the state that an N type InP buffer layer 1', an InGaAsP active layer 2, a P type InP clad layer 3, and a P type InGaAsP ohmic contact layer 4 are crystal-grown after removal of the photoresist 9. The state of crystal growth at this time shows crystal growth with a thickness of the degree that the trace of the groove provided in the Fig (a) remains. The Fig (c) shows the state that mesa etching is carried out with an etchant having no crystal selectivity to InGaAsP and InP. The etched state at this time shows an etching deep on both sides because of the trace of the groove provided first and shallow at the other part. Successively, a P type InP buried layer 5, an N type InP blocking layer 6, and a P type or N type InGaAsP crystal protection layer 7 are grown.

Abstract: PURPOSE:To shorten the processing time per I/O instruction, to reduce a competition of an access, and to improve the performance of the system by holding the coupling of a channel device and a magnetic disk device even after a data transfer is ended. CONSTITUTION:When an actuation to a logical volume '0' is issued from a CPU 11, a channel device 12 starts a selection processing to the logical volume '0', and when it is coupled with a disk device 19, a command is issued. When a transfer of data is ended and an end status from a disk controller 20 is received, the channel device 12 does not disconnect the coupling with the magnetic disk device 19 but holds the coupling, and immediately executes an end report to the CPU 11. When the next actuation is applied to a logical volume '1', it is judged to be in a ready state because of the same disk device, and a command is issued immediately without executing the selection processing. In such a way, the processing time per I/O instruction can be shortened, a competition of an access can be decreased, and the performance of the system is improved.

IPC: B22D19/00
Filed: 1985-10-30
Abstract: PURPOSE:To improve a strength of product ad to reduce a production cost by casting molten metal as casting therein a pipe which previously insets a core material at an axial center position of a shaft in a mold. CONSTITUTION:A pipe 5 which is previously shot-blasted, is arranged at almost axial center position in the mold and inserts the core material 9 therein. Next, a hollow cam shaft 1 is formed by casting the molten metal as casting therein the pipe 5 in the mold. At this time, expansion parts 6, 7 of the pipe are formed previously by bulging work at corresponding positions of a cam piece part 2 and sprocket fitting part 4 of the cam shaft. As the core material 9 is inserted into the pipe 5, the shaft is prevented from bending, and the strength of shaft is improved because of large Young's modulus of the pipe 5. Further, as the long core is unnecessary in this casting, the production cost is reduced so much.

Part of light projected on the white toner part 6 is reflected irregularly by the white toner surface and guided to a photosensitive body, but the remainder is transmitted through the white toner part 6 and travels to the aluminum vapor-deposited sheet 1. This light is reflected partially by the transparent film surface of the aluminum vapor-deposited sheet, but the majority of it is guided into the transparent film and reflected by the aluminum layer 3. Consequently, the contrast is improved.

Filed: 1984-11-20
Abstract: PURPOSE:To enable connection of two members in a limited space by fixing both ends of a wire to the two members relatively rotatable with each other respectively and arranging the wire along a retaining band. CONSTITUTION:When a turning shaft 23 is turned to move to the direction of an arrow mark A to a fixed shaft 21, a retaining band 31 keeps its bending while moving a curved bent wire 31a to the peripheral direction sequentially. Therefore, the other end 31a of the retaining band 31 fixed to a flange 23a of the turning shaft 23 is moved to the peripheral direction smoothly. In this time, a power supply electric wire 32 is bent and deformed under the condition where it is arranged along the retaining band 31 and does not make uncertain movement in the fixed shaft 21. As the electric wire 32 is covered by the steel retaining band 31, breaking of the wire 32 can be prevented and induction current among wires can be prevented.
