Title: Self-priming vertical pump assembly
Inventor: TANABE MASATOSHI
IPC: F04D29/62
Filed: 1981-06-05
Abstract: PURPOSE:To simplify the structure of a base and a bracket for constituting a pump and to also simplify the molding operation in fabricating the base and bracket, by reducing the number of component parts considerably by forming a suction port and a discharge passage in the base, and employing such an arrangement that an air separating chamber is formed when the base is assembled  to the bracket. CONSTITUTION:A bracket 1 is designed such that a casing cylinder 12 for defining a pump casing and an air separating chamber 13 are formed therein, while a suction port 27 and a discharge port 33 are prefabricated in a base 26. The bracket 1 and the base 26 are coupled together in a watertight manner by means of bolts 35, with an O-ring 36 being interposed therebetween. Thus, the air separating chamber 13 is not formed until the base 26 formed with the suction port 27 and discharge port 33 is coupled with the bracket 1. By employing such an arrangement, it is enabled to simplify the configuration of the base 26 and the bracket 1, to simplify the molding tools in molding them with a synthetic resin, and also to simplify the molding operation.

Title: Method and device for controlling optical disk
Inventor: TAKAHARA TAMANE
IPC: G11B7/09
Filed: 1989-04-06
Abstract: PURPOSE:To easily control the pickup even at the time of a high speed access by detecting a bit train as a binarizing signal, and executing a position control, based on this binarizing signal, in the case when it is different from a binarizing signal recognized already. CONSTITUTION:To a binarizing shaping part 22, a signal from a Gray code part of a servo-byte area is inputted, and it is brought to binarizing shaping. A position detecting part 23 refers to a pattern stored in a binarizing pattern storage part 30 and discriminates a pattern which a binarizing signal coincide with, and by a cross track number detecting part 25, the number of tracks which a pickup intersects with is calculated. In such a way, in the case when the pickup passes through one track in about several cycles, even if an address cannot be read, the present position of the pickup is detected and it can be controlled easily, based on position information immediately before starting a high speed access stored in a memory 24 at the time of a regular operation mode.

Title: Polyamide-imide resin composition
Inventor: KUBO YASUSHI
IPC: C08L71/08
Filed: 1979-07-09
Abstract: PURPOSE: A polyamide-imide resin composition, having balanced flow and mechanical characteristics, composed of an aromatic polyamide-imide resin and a specified amount of a polyphenylene ether resin.  
     CONSTITUTION: A composition, composed of (A) 5W99.9wt% of an aromatic polyamide-imide resin, having a repeating unit of the formula (wherein Ar is a trivalent aromatic residue, including a 6C ring; R is 9 bivalent aromatic and/or aliphatic residue; R' is methyl or phenyl), as the main structural unit, (B) 0.1W 50wt% of a polyphenylene ether resin, and (C) 0W70wt% of a filler. The polyphenylene ether resin contains a phenylene ether linkage as a part of the reapting unit and is decomposed at a temperature ≥350°C. A polyphenylene ether resin of decomposition temperature <350°C, is unsuitable, because it is so thermally unstable, that it tends to be thermally decomposed, which makes stable mixing difficult.

Title: Apparatus for producing metallic powder
Inventor: NAGANO MISAO
IPC: B22F9/10
Filed: 1985-04-22
Abstract: PURPOSE:To consume uniformly a material to be melted without using the same as a consumable electrode by forming a plasma arc torch facing the material to be melted under rotation at high speed in a hermetic chamber to a non-transfer type so that the top end thereof can be displaced in the direction intersecting orthogonally with the axial center. CONSTITUTION:The inside of the hermetic chamber 1 is maintained under an Ar gaseous atmosphere and the material 7 to be melted is rotated at high speed. Gaseous plasma is supplied to the plasma arc torch 10 and a DC power source superposed with a high frequency is passed from a power source 18 to the torch 10 to operate the same. The top end of the material 7 is thereby melted by which a molten metal is scattered and pulverized powder is formed. The torch 10 constitutes a negative electrode and a water cooling nozzle 15 a positive electrode and therefore there is no need for passing the DC large current to the revolving shaft of a high-speed motor 5 and safety is improved. The displacement of the top end of the torch 10 is made possible by oscillating and adjusting the torch around a spherical body 21 and therefore the uniform melting and consuming of the material 7 are made possible.

Abstract: PURPOSE:To avoid a line from being excessively used with a specific terminal station, by permitting the assmignment of lines only when the number of satellite lines to be used is smaller than a predetermied value or if the number of vacant satellite lines is greater than the predetermined value. CONSTITUTION:When a line usage request is received from a terminal station 5, an address corresponding to the terminal station 5 is set to an address line 8, the number of lines used by the terminal station 5 is stored in an address 59 of a memory 50 and the number of holding and stop calls of the terminal station 5 is stored in an address 60 of a memory 51. The content of both the addresses 59 and 60 of the memories 50 and 51 are compared at a comparison circuit 55, and when the condition of the content of the memory 59 (number of lines to be used) < content of the memory 60 (number of times of holding calls) is satisfied, an output 61 of the comparison circuit 55 goes to logical ''1''. Thus, in this case, the terminal station 6 have not used the lines to the number of times of holding calls, then the permission for the assignment of lines is made. Simultaneously, the content of a register 52 indicating the number of vacant lines and the content of a register 53 indicating the number of holding lines are compared at a comparison circuit 54, and if the former is greater than the latter, the assignment of lines can freely be permitted.

Title: Accelerating accumulation conveyor chain
Inventor: MURANO TETSUYA
IPC: B65G47/28
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an accelerating accumulation conveyor chain which can exhibit a smooth accelerating function and an accumulating function without requiring excessive chain driving force, eliminate noise such as loading and sliding sound caused by the shortage of lubricant for a chain, and let inspection and maintenance be simple. SOLUTION: A large diameter loading roller 15 and small diameter running rollers (16) and 16 are coaxially and loosely fitted into a sintered and oil containing bush 11 in which a connection pin 12 for a plate is loosely fitted. Since a gradual oil releasing action is performed, which allows lubricant to be slowly emitted from the sintered and oil containing bush 11, the whole of a chain can be run by small chain driving force in a state that a low frictional coefficient can be kept stable in the loosely fitted-in part of the bush 11 with respect to the loading roller 15 and the running rollers (16) and 16, and in the loosely fitted-in part of the bush 11 with respect to the connecting pin 12, so that an accelerating function and an accumulating function can thereby be exhibited by the loading roller 15 and the running rollers 16.
