Filed: 1991-02-28
Abstract: PURPOSE:To eliminate separate provision of a heating source for a lubricant oil without changing the fundamental configuration of a compressor, raise the temp. of the lubricant still higher, and retain high the lubricating performance of the lubricant. CONSTITUTION:A rotary compressor 4 to compress gas and discharge it into an enclosed case is accommodated in the lower part of the case 1, and at the inner bottom of this enclosed case an oil sump 25 is formed which admits stagnation of lubricant oil to be led to sliding parts.

Abstract: PURPOSE:To simplify the designal arrangement for the movable parts of a four-cycle diesel engine, by forming an airtight chamber upwardly of a guide piston in a guide cylinder, so that upward inertia force acted by the lower portion of movable parts at the time of their upward stroke can be compensated. CONSTITUTION:Arrangement for a four-cycle diesel engine is such that a guide piston 13 is connected to the lower end of piston rod 12 that is connected to the upper end of piston 11, and connecting rod 14 connected at its upper end to guide piston 13 pivotally by pin 13' is connected at its lower end to crank 15 in pivotally movable manner. In such an arrangement, an airtight chamber 16' is formed upwardly of guide piston 13 in guide cylinder 16 in which guide piston 13 is moved straight in vertical direction. When exhaust valve 18 disposed upwardly of cylinder liner 17 is opened during  exhaust stroke and pressure on the upper side of main piston 11 is lowered, a large upward inertia force is acted by movable parts 11-15. However, this upward inertia force can be compensated since air in the airtight chamber 16' is compressed by guide piston 13.

Title: Hydraulic pump
Inventor: OCHIAI MASAMI
IPC: F04B1/20
Filed: 1982-03-05
Abstract: PURPOSE:To improve the self-priming function of a hydraulic pump, by drawing fluid from a suction port into a cylinder chamber through fluid passages in the form of oblique holes which are inclined in the direction of rotation of a cylinder rotor. CONSTITUTION:Fluid passages 23 are shaped in the form of oblique hoes inclined in the direction R of rotation. That is, they ae inclined from cylinder chambers 22 toward a sliding surface 9 in the direction R of rotation of a cylinder rotor 21. Providing that the fliuid passage 23 is a branch pipe B and a suction port 10 is a main pipe A, the velocity of fluid flow is increased and the loss factor is reduced by connecting the branch pipe B to the main pipe A at an inclination angle theta. Resultantly, pressure loss during the suction stroke is also reduced. Therefore, even if the velocity W of fluid flow is inceased by increasing the speed of rotation of a pump, it is enabled to keep the suction pressure high during the suction stroke and to exert a sufficient self-priming function.

Title: Non-volatile semiconductor memory
Inventor: ASARI SEIICHIRO
IPC: G06F21/79
Filed: 1990-02-15
Abstract: PURPOSE:To prevent various signals from an external part from turning into data by fitting a read-only external terminal, setting it to execute reading in a certain state and setting it to execute regular functioning in other state. CONSTITUTION:An H level or an L level is statically fixed to the external terminal 11, and it is connected to an internal circuit. At the time of the H level, a mode is set to a regular one, namely, writing into and reading from a memory can be executed and a signal with which the system comes to a write mode is received. At the time of the L level, only reading is executed and the write mode is turned off. Thus, the memory can sufficiently protect an unstable signal and an unexpected signal, both of which come from the external part.

Title: Centrifugal compressor
Inventor: MIURA HARUO
IPC: F04D17/12
Filed: 1993-02-24
Abstract: PURPOSE:To stabilize rotor vibration by setting a number of fins of a stage labyrinth so as to be more than that of an eye labyrinth, so as to improve spring action, in a centrifugal compressor to be driven by revolutions in excess of the primary critical speed of a rotor. CONSTITUTION:The number of fins of a stage labyrinth 21 for preventing leakage to an outlet of an impeller 1 from an outlet of a return channel 10 is so set as to be more than that of an eye labyrinth 6 for sealing the clearance between a side plate of the impeller 1 and a stator. That is, the number of fins of the eye labyrinth 6 is set to four, while the number of fins of the stage labyrinth 21 is set to 6. Since swirling component of leaked flow of the stage labyrinth 21 is eliminated by a return vane 10a, the spring force for stabilizing the rotor vibration by spring effect to be generated on a seal portion is approximately proportional to the number of fins of labyrinth part, so that the stabilizing force can be increased by this structure.

Filed: 1987-02-18
Abstract: PURPOSE:To provide the titled equipment for high-speed spinning of high-quality spun yarn where a revolving pie with fiber bundle passage and a revolving disc integrally formed apart from the inlet of said pipe are covered with a specific casing. CONSTITUTION:A revolving disc 26 is integrally formed in front of the bearing 18 of a revolving pie 19, and a fiber bundle passage 24 is formed at the center of said pipe 19 in a penetrating manner. A compressed air through a hose 29 is emitted via an air space 31 through a nozzle 27 into a hollow space 51, thus producing a high-speed whirling air stream in the proximity of the revolving pipe inlet 19a. After whirling in the hollow space 51, this stream is dispersed outward while whirling gradually in a conical hollow space 52, being then discharged. This air stream creates a suction air flow from the nip N of the front roller 4 into the hollow space of the casing 15.

Title: Recording medium recording command menu program module and information processor
Inventor: HASHIKURA FUMIO
IPC: G06F3/0481
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce operation required for menu page switching by displaying a subordinate menu for preferentially displaying a command having high use frequency. SOLUTION: The use frequency of each command is recorded (S1). Each time the command is selected/executed, which command is executed is recorded, the use frequency of each command is found, and a command execution time table is generated by successively arranging commands from high execution time to low execution time (S2). Among the commands in the high order of command execution time table, the command not registered in the displayed menu is extracted (S3). Concerning the extracted command considerably increasing the number of times of command execution with the repeated selection/ execution of command according to a main menu and the subordinate menu, the command to be extracted in the command exetraction (S3) is changed so that the subordinate menu can be updated at such a time (S5). The constitution of main menu is not affected by the fluctuation of order.
