Title: Optical connector and its manufacture
Inventor: KOZU GIICHI
IPC: G02B6/38
Filed: 1989-11-09
Abstract: PURPOSE:To obtain the optical connector which has superior reliability and is easily reducible in size and good in operability by arranging support rods which are equal in diameter in contact so that the center axes of three rods are arrayed at plane regular triangle positions and inserting and supporting an optical fiber in the center cavity part formed by pressing and holding the respective rods. CONSTITUTION:The optical fiber 1 is held in a connection body by a holding member 2. The holding member 2 consists of a hollow cylinder body 3 and plural straight support rods 4 which are sectioned circularly and inserted into the hollow part of the hollow cylinder body 3 axially. Those equal-diameter support rods 4 are arranged in contact so that the center axes of the three rods are arrayed at plane regular triangle positions, and the center gap part formed by pressing and holding the respective support rods 4 is used as the optical fiber support part 5 of a single-unit optical connector. Consequently, the concentricity of the optical fiber is easily maintained, the straightness and hole size accuracy of a ferrule itself are improved greatly, and the high- reliability optical connector which has no error is obtained; and the productivity is improved, the working cost is reduced, and the size is reducible.

Title: Hydraulic double clutch
Inventor: TANAKA HARUO
IPC: F16H3/44
Filed: 1992-10-28
Abstract: PURPOSE:To make the locking of a first clutch part desirable by forming a second spline part, smaller in diameter than a first spline part, adjacently to this opening part side first spline part for engaging a clutch plate with a first clutch drum, and engaging a second clutch drum with this second spline part. CONSTITUTION:When pressure oil is fed to a first oil chamber 10, a second clutch drum 7 is pushed to move onto the opening part side of a first clutch drum 6, and the clutch plates 4a of a first clutch part 4 are pressed by the second clutch drum 7 to lock the first clutch part 4. The second clutch drum 7 is engaged with a second spline part 13 smaller in diameter than a first spline part 12. The clutch plate 4a part opposed to the opening part end face of the second clutch drum 7 is thereby dislocated inward from the outer peripheral part of the clutch plate 4a to be the engaged place to the first spline part 12, so that the clutch plate 4a is brought into pressure contact with the inner clutch plate 4b without being inclined. The first clutch part 4 is thereby locked desirably.

Title: Production of co-ni-cr system alloy target material
Inventor: MIZUGUCHI TAKEO
IPC: C23C14/34
Filed: 1987-11-17
Abstract: PURPOSE:To produce a target material which is capable of executing good sputtering even if a sheet is thick by subjecting the target material to cold working at a specific reduction ratio then to stress relief annealing at a specific temp. CONSTITUTION:The forged and rolled material obtd. by hot working of an ingot is subjected to the stress relief annealing and is thereafter subjected to the cold working at 10-70% reduction ratio, then to the stress relief annealing at 600-90 deg.C. The max. magnetic permeability (mum) of the target material is lowered by the cold working of this case. However, the material is deformed to a desired shape and size before the cold working and, therefore, the material is subjected to the stress relief annealing. Since the recovery by this annealing leads to a decrease in internal stresses, the mum increases. This phenomenon is more liable to arise as the number of the defects introduced into the material is larger if the annealing temp. is the same. The upper limit of the reduction ratio is, therefore, confined to 70%. On the other hand, the sufficient effect of decreasing the mum is not obtainable if said rate is below 10%. The stress relieving is insufficient if the temp. of the annealing to be subsequently executed is below the lower limit. The magnetic recovery increases considerably if the temp. exceeds the upper limit.

Title: Printer
Inventor: YAMAUCHI MITSUGI
IPC: B41J29/38
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To reduce a current consumed by a plurality of ROMs by a method wherein a chip enable switching circuit which gives a fixed level signal when a CPU operates in a specific operation clock, and a ROM decode signal when the CPU operates in a slower clock than the specific operation clock to respective ROMs, is provided. SOLUTION: When a CPU 1 wherein a normal mode in which it operates in a specific operation clock, and a power save made in which it operates in a slower clock than the specific operation clock are convertible to each other, operates in the power save mode, ROM decode signals 10a-10d are outputted as they are CE bar signals 20a-20d. Then, since the decode signals 10a-10d are given to ROM 30a-30d in access to a ROM circuit part 30, only the accessed ROM in the ROM 30a-30d comes to be in a chip enable state. Since the other ROMs do not come to be in the chip enable state, the consumed current of the ROM is reduced.

Title: Oil seal structure
Inventor: SAWASE KAORU
IPC: F16C33/72
Filed: 1994-11-25
Abstract: PURPOSE: To perfectly seal the oil a casing until a second rotary shaft is connected and surely supply oil to a connection section after the connection of the second rotary shaft. CONSTITUTION: The lip of a seal body is slidably brought into contact with the internal surface of a casing 1 with a right output shaft 25 disconnected to seal between a medium shaft 21 and the casing 1 by the seal body. In the case where one end section 26 of the right output shaft 25 is fitted to one end 22 of the medium shaft 21, the end section 26 of the right output shaft 25 presses the projection of the seal body, resulting in the separation of the lip from the internal surface of the casing 1, producing a gap between the internal surface of the casing 1 and the medium shaft 21, allowing the oil in the casing 1 to flow to a fitting section side. Until the right output shaft 25 is connected, the oil in the casing 1 is perfectly sealed, and after the connection of the right output shaft 25, oil is surely supplied to the connection section.
