Title: Method of fitting tie plate to sleeper
Inventor: ISAKA SEIJI
IPC: E01B9/44
Filed: 1989-05-13
Abstract: PURPOSE:To firmly fit a tie plate to a composite sleeper without reducing the service life of the sleeper by fitting the tie plate to the sleeper by not using any fixing nail, but a bonding agent. CONSTITUTION:A composite sleeper 10 is formed to a pillar-like body of a foamed thermosetting resin and reinforcing long fibers. A tie plate 11 is bonded to the sleeper 10 with a, for example, epoxy bonding agent after the surfaces of the sleeper 10 and tie plate 11 to be joined together are smoothed and cleaned. Fixing devices 12 on both sides of a rail 13 fix both side sections of the rail 13 to the tie plate 11 by means of one ends of plate springs when the plate springs 15 are compressed by nuts 17 engaged with bolts 16. Therefore, the fixed state of the rail can be stabilized without reducing the fitting strength of the tie plate due to the corrosion of a fixing nail.

Title: Water repellent film forming method for hermetic terminal
Inventor: WACHI TAKESHI
IPC: H01R9/16
Filed: 1990-05-09
Abstract: PURPOSE:To let coating material dispense with organic solution by applying coating material the viscosity of which is adjusted in such a way that water is added to aqueous emulsified silicone oil, on a hermetic terminal so as to be dried and then baked thereafter, and thereby forming a water repellent film. CONSTITUTION:The outer and inner exposed faces A and B of glass 4 which insulate a lead wire 3 from a metallic ring 1, is formed with a water repellent film 7. The exposed faces A and B are applied with coating material which is diluted to several % in such a way that water is added to aqueous emulsified silicone oil till non-volatile residue will be 2 to 5% by weight, by spraying and/or dipping methods so that the water repellent film is thereby formed. In the second place, coating material applied to glass 4 is dried in air, and is then baked so that the exposed faces A and B are formed with the water repellent film 7 as required. The water repellent film 7 thus formed prevents insulating resistance and voltage resistance between the metallic ring 1 and the lead wire 3 from being lowered. Since no organic solution is contained in coating material, methods as described above are inexpensive and free of pollution, thereby lowering the cost of manufacture.

IPC: F04C15/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a lubricating oil pump for a vehicle with controlled vibration of the pressure of hydraulic oil which is discharged from the lubricating oil pump. SOLUTION: As a vibration control means for controlling vibration of an oil pump, vibration easing roads 100, 102 of a fixed capacity, with a predetermined length and a predetermined section area smaller than a first discharge oil passage 86, are provided between the first discharge oil passage 86 and the uppermost stream side positions of a first discharge port 84. Accordingly, the existence of vibration easing roads 100, 102 reduces the change in pressure of the hydraulic oil in passing from a pump chamber 58 through the first discharge port 84 or a second discharge port 92. Thereby, a sudden release of the hydraulic oil is prevented. In other words, generation of periodic vibration of pressure, i.e., pressure oscillating wave, that is caused by the sudden pressure change (or drop) of the hydraulic oil is preferably eased.  Therefore, vibration and noise of other members that are excited directly or indirectly by the vibration of the gear type lubricating oil pump containing the hydraulic oil are preferably prevented.

Title: Dead region management processing method
Inventor: MURAKAWA IKUKO
IPC: G06F12/02
Filed: 1987-05-19
Abstract: PURPOSE:To merge the continuous dead regions with high efficiency by inverting the bits corresponding to the dead regions and constituting a single region at every range where the inverted bits are continuous on a bit map corresponding to a memory area. CONSTITUTION:When the regions are merged with each other, the bit maps are arrayed in response to each unit region of a memory region and all bits are initialized at the OFF values for example. A dead region control table and the bit maps corresponding to the leading address of each item through the final address decided by the size of said leading address are changed to ON states. Then the bit map is scanned to produce the control information at every range where the inverted bits are continuous from the leading address and the region size as one item of the dead region management table. Thus it is possible to complete the region merging processing with a single scan of the dead region management table and the bit map.

Title: Picture mask device
Inventor: KOYANAGI HARUO
IPC: G06V10/10
Filed: 1981-08-05
Abstract: PURPOSE:To speed up the pattern recognition, by picking up a picture signal including a specific objective picture only from a picture signal including a plurality of objective pictures outputted from an image-pickup means. CONSTITUTION:A TV camera 1 outputs a picture signal SV including pictures A and B corresponding to, e.g., two objectives respectively. A memory 2 stores binary picture data in which each picture element corresponding to the masked part for masking the picture B and each corresponding to unmasked part are taken (0) and (1) respectively as masking picture data M to pick up the picture A only. When the data M is zero, since an analog switch AS1 of a mask control circuit 5 is turned off and an AS2 is turned on, a picture signal SVO indicating a background other than the pickup objective is outputted from a light level voltage generating circuit 6. When the data M is (1), since the switches AS1 and AS2 are respectively turned on and off, the signal SV is outputted as it is. Thus, the storage of picture data can be attained with a series of operation, then the pattern recognition can be quickened.
