Title: Vertical motor pump
Inventor: NAKANO MASAAKI
IPC: F04D15/00
Filed: 1980-11-14
Abstract: PURPOSE: To reduce thrust load in a low viscosity liquid of the captioned pump for drawing up low viscosity liquid such as extreme low temperature liquid by providing a material haing small friction coefficient on the opposite mutually facing surfaces of a rotary ram and fixed cylinder.  
     CONSTITUTION: A substance 30 having a small friction coefficient such as copper alloy is fitted to the outside peripheral surface of a rotary ram 22 facing a fixed cylinder 21 forming a load reduction means 20 with a longitudinal clearance h1 and a transverse clearance h2. With this construction, the low friction member 30 which is very effective to lubricate in a low viscous liquid, lays a role to reduce the generation of heat, thereby preventing the generation of bite or other factors, and making it possible to operate in safety, even when the fixed cylinder 21 makes a sliding contact with the rotary ram 22. Therefore, thrust load in a low viscous liquid can be reduced.

Title: Inkjet recorder
Inventor: TSUZUKI MITSUO
IPC: B41J2/045
Filed: 1983-08-31
Abstract: PURPOSE:To enable the formation of drips stably at a high speed while reducing energy loss by a method wherein a fluid resistance element is arranged between a nozzle and a pressure chamber while a fluid flow smoothening element between the pressure chamber and an ink feed port with the direction of the pressure chamber set forward to make the resistance of the fluid resistance element higher than the resistance of the fluid flow smoothening element. CONSTITUTION:When a voltage is applied to an electromechanical conversion means 2 from a driving means 7, a fluid flow smoothening element 5 comprising a check valve or the like for checking the flow in the direction of an ink feed port 4 is reversed and the ink extruded from a pressure chamber 3 is jetted in ink drips from a nozzle 1 passing through the fluid resistance element 6. Then, as the voltage changes to the original value, ink is sucked into the pressure chamber 3 with the pressure in the pressure chamber 3 becoming negative. Here, the less the forward resistance value of the fluid flow smoothening element 5 is than the resistance value of the fluid resistance element 6, the less the ink to be sucked into the pressure chamber 3 from the nozzle 1 side is. This can reduce the time required for the return to the initial condition to enable a high-speed operation thereby minimizing the energy loss spent on the operations other than the drip formation.

Abstract: PURPOSE:To reduce a difference of thermal expansion for lightening a rudder frame by providing a bearing cap member defining a crankshaft bearing part on the rudder frame body connected to a cylinder block by a fastening bolt to making the maximum height of the cap member smaller than that of the rudder frame body. CONSTITUTION:A bearing cap member 14 made of cast iron is cast into a rudder frame body 13 made of aluminum alloy so that the maximum height h of the member 14 is made smaller than that H of the rudder frame body 13. While the rigidity of the rudder frame is not damaged, even the iron made crankshaft 2 does not so much differ in the coefficient of thermal expansion and the thickness of a cross beam 16 or the like is not needed to increase since a load on a bearing part 18 is supported by the bearing cap member 14. The rudder frame construction is substantially lightened by reducing the difference of thermal expansion and ensuring the load strength to display the rigidity thereof.

Title: Magnetic disk device
Inventor: MURAOKA HIROAKI
IPC: G11B5/09
Filed: 1987-06-26
Abstract: PURPOSE:To prevent a leakage flux from being generated from an erasing head at the time of recording, by setting the cavity length of the erasing head larger than length equivalent to the product of the maximum stoppage time of a current being impressed on the erasing head and the maximum relative velocity between a magnetic head and a magnetic recording medium. CONSTITUTION:The operating time TE of a monostable multivibrator 22 is set smaller than the minimum pulse interval T of a write data signal 21. A period tS when an erasing current stops is set as tS<2T-tE against the pulse interval 2XT of the maximum write data. Therefore, by selecting the cavity length GE of the erasing head so as to be GE>tSXVmax against the maximum relative velocity between the head and the medium, it is possible to set all of the areas so that the magnetic field of the erasing head can be impressed on them on the medium. In such a way, it is possible to stop a harmful leakage flux from the erasing head at a moment to write magnetization inversion on the medium.
