Title: Suction device of multi-cylinder internal combustion engine
Inventor: MOTOSUGI KATSUHIKO
IPC: F02M35/10
Filed: 1981-09-08
Abstract: PURPOSE: To increase greatly the combustion speed at the time of low speed and low load and thereby obtain a stabilized combustion by installing a throttle valve in the neighborhood of a helical suction port and arranging a communicative branch, open at the suction port, in communication with a mutual branch duct.  
     CONSTITUTION: A throttle valve 22 is installed at the suction port 5b of helical type. At the time of low load operation of the engine, a gap 33 for passage of mixture is formed to give the mixture high speed and permit it to flow eccentrically located nearer the overwall of the suction port 5b, to be sent to the combustion chamber 10 through a suction valve 3b. A communicative branch 30b is led to the suction port 5b and opened at its inner wall, through which the mixture fed through a communicative branch 30b will jet out under the suction stroke. The turbulence thus generated in the combustion chamber 10 will increase the combustion speed greatly and assure a stabilized combustion.

Title: Mobile communication system, packet transfer method for mobile communication system and terminal base station used for mobile communication system
Inventor: ASAKAWA YOSHIAKI
IPC: H04W36/30
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To attain packet communication with high reliability by configuring the system such that plural base stations receiving transmission packets from terminals transfer the packets to a base station control station and the base station control station selects the transmission packets with less transmission errors among the received transmission packets and transfers the selected packets to a network. SOLUTION: A terminal 101 sends an incoming control packet to a base station 104 being a communication opposite party to request packet communication and the base station 104 sends an acknowledgement packet to the terminal 101. A base station 105 that is not the communication opposite party and receives this incoming control packet reserves a channel for a prescribed time to receive a transmission packet corresponding to the incoming control packet. The terminal 101 sends the transmission packet according to contents of the acknowledgement packet to the base stations 104, 105, and the base stations 104, 105 receiving the transmission packets transfer the packets to a base station control station 106.  The base station control station 106 selects a transmission packet with less transmission errors from the transmission packets received from the base stations 104, 105 and transfers the selected packet to a network.

Abstract: PURPOSE:To permit a cutter polishing machine to always properly polish a cutter used in a wood planing machine or the like as well as improve its polishing efficiency by allowing a grindstone to automatically approach a given position adjacent to the surface to be polished corresponding to the abrasion of the grindstone. CONSTITUTION:A cutter holder 7, to which a surface 10' of a cutter 10 to be polished is attached almost vertically, is reciprocatable. Rotating grindstones G1 and G2 are arranged so as to be movable in the direction of the reciprocation. When the grindstone surface has contacted with the surface 10' of the cutter 10, the cutter holder 7 is counterclockwise turned to move the surface 10' slightly backwards as well as a limit switch LS-A is actuated. This causes the power circuit of either a motor M5 or M6 for feed to be opened to stop the advance of the grindstone G1 or G2. Simultaneously, through the other contact in the limit switch LS-A, a solenoid SOL is energized to secure the cutter holder 7 by the attraction force.

Abstract: The present invention provides an improved process for producing from used oil a lube oil base stock suitable for use in automobile lubricating oil comprising the steps of:   (a) pretreating used oil to remove hydrofinishing catalyst fouling materials to give a pretreated mixture; (b) distilling the pretreated mixture from step (a) to separate a lower boiling distillate fraction which boils at less than 150 DEG C, a gasoil distillate fraction; and a lube oil distillate fraction from an asphalt fraction; and   (c) hydrofinishing the lube oil distillate fraction from step (b).   In step (a), a sufficient amount of an alkali compound is added under vigorous mixing conditions and in the presence of at least about 3% water to give a pH of at least about 5 in the gas phase of all the distillates produced in step (b). The conditions in step (a) can additionally be chosen so that substantially all free phosphorus is converted to an insoluble phosphate or phosphoro compound.
