Title: Valve seat for internal combustion engine
Inventor: ITO YOSHIHIKO
IPC: F01L3/02
Filed: 1992-08-24
Abstract: PURPOSE:To provide a valve seat composed of a sintered body including lead as a lubricant in high temperature in an internal combustion engine, which can maintain the lubricating action of the lead for a long period. CONSTITUTION:A valve seat 10 is composed of two layers, i.e., a valve contacting layer 10b contacting a valve 2 of an internal combustion engine and a layer 10a rich in lead and sintered integrally with the valve contacting surface 10b. The valve contacting layer 10b is composed of a sintered body having 7.2-7.5g/cm<3> of density and lead infiltrated therein. The layer 10a rich in lead is composed of a sintered body having 6.6-7.0g/cm<3> of density and lead infiltrated therein. Since the valve contacting layer 10b has the high density and small empty holes, a proper amount of lead is supplied from the surface of the layer 10b when the temperature of the valve seat 10 exceeds the melting point of the lead.

Inventor: SHIMIZU TAKESHI
IPC: B29C45/34
Filed: 1995-08-31
Abstract: PURPOSE: To obtain a resin seal part free from air bubbles and a sink by discharging air, gas or the like from a mold cavity by opening the mold cavity to the atmosphere through a porous part or injecting a molding resin under pressure sufficiently lower than molding resin injection pressure. CONSTITUTION: A resin tablet 46 heated by a preheater is placed on a plunger 45 and a lead frame 42 is interposed between both mold main bodies 24, 34. A cylinder is driven to move a lower mold unit toward an upper mold unit 21 to allow the same to approach the unit 21 and a space containing a cavity 43 is formed. The tablet 46 brought to a molten state is pressed by the plunger 45 driven by the cylinder to allow a resin material to flow in the cavity 43 through a runner 47. Since the mold main bodies 24.34 are wholly constituted as air passing parts, the gas in the runner 47 and the cavity 43 is discharged to the outside through the mold main bodies.

IPC: G21C17/035
Filed: 1990-08-28
Abstract: PURPOSE:To make the driving and monitoring operation of the operator of a plant easier so that the plant can be operated safely after a fault occurs by only outputting necessary fault information regarding the fault which occurs during the operation of the plant. CONSTITUTION:This alarm signal controller for plant is provided with a signal storing means 1 which stores process signals, plant controlling signals, and alarm signals from job sites and a correlation storing means 2 which stores the correlation between alarm signals and the stored contents of these storing means 1 and 2 are supplied to an alarm signal discriminating means 3 as required.

Title: Access control circuit for optical disk device
Inventor: SUZUKI YASUHIRO
IPC: G11B7/085
Filed: 1990-08-27
Abstract: PURPOSE:To prevent miscounting due to vibration, etc., and to enable the correct counting by performing a changeover operation based on a hysteresis changeover signal and setting a hysteresis characteristic of a binarization threshold in a pulse generating part at a prescribed width at the time of a tracking control. CONSTITUTION:When the hysteresis characterisitc is imparted to the binarization threshold C, and then the number of corrsing tracks is counted, since the hysteresis characteristic is large at the time of the tracking control, even when a variation is generated in an amplitude of a track crossing signal S1 due to vibration, etc., this variation width will never reach the threshold C. As a result, since the threshold C at the time of starting the counting can be maintained at a preset L-level, miscounting of the 1st pulse at the time of beginning the counting can be prevented. At the time of an access control, since the counting is performed by diminishing the hysteresis, even when the track crossing signal S1 is varied in amplitude, no counting is prevented. By this method, the correct counting is feasible.
