IPC: B22C9/06
Filed: 1994-10-21
Abstract: PURPOSE: To surely execute the sealing at the time of closing a valve without deforming at a metallic sealing part by arranging the rear end part of a valve rod so as to be freely slide in a spool as a piston and forming as the surface contacting to a valve part between the piston and a valve guide, and a valve seat part. CONSTITUTION: In a gas venting device 34 in a die, the valve guide 12, in which the valve is freely slid, is arranged, and the spool 44 is engaged with this valve guide 12 and freely shifted in the sliding direction of the valve with a cylinder 64 and can be set into the dies 30, 32.

Title: Manufacture of resin mold semiconductor device
Inventor: TOTOKAWA MINEHIDE
IPC: H01L21/56
Filed: 1984-12-05
Abstract: PURPOSE:To enable formation of the resin body which is thin and hard to be peeled by arranging a supporting plate in a forming cavity of a mold for resin molding and pouring a liquid resin to form the molded resin body. CONSTITUTION:As the front end 14 of a supporting plate 2 is divided into two, two pins 15a and 16a are arranged. A cylindrical pin 15b extends downward from the top force 15 and contacts with the bottom force 16. A projecting part 15c formed into a partition for restraining a flow of the resin projects downward from the top force 15. A distance between the end of this projecting part 15c and the supporting plate 2 is small than that between the top force 15 and the supporting plate 2 in the vicinity of the pin 15b, so that a flow of the resin is restricted there. The heat-curable epoxy resin made into a slime by heating is driven into and fills the cavity 16 through a pour hole 18. The top and bottom forces 15 and 16 have been heated to a heat curable temperature of the resin and the resin which was driven into and filled the cavity cures by heat in a short time and a molded resin body 19 is formed. Thus the resin body which is thin and hard to be peeled can be formed easily and well.

Title: Slant detection device
Inventor: HIRANO TADASHI
IPC: G01C9/12
Filed: 1990-09-28
Abstract: PURPOSE:To enable slant angle in an arbitrary direction to be detected with improved accuracy by allowing light emitted from a light-emitting element to be reflected by a reflection plate which is provided at a lower edge part of a plumb member which is supported rotatably around a support and to be received by an optical sensor. CONSTITUTION:An optical sensor 5 consists of a light-emitting element 5a and a light-receiving element 5b for receiving reflected light emitted from this light-emitting element 5a. When a fixing member 1 is held horizontally, an optical sensor which is provided at a bottom plate 2 opposes a central point of a central surface part 9a with a low reflectance of an above reflection plate 9. Therefore, output signal of the optical sensor is off. When the amount of relative rotation between the reflection plate 9 of the lower edge of a plumb member 8 and the fixing member 1 exceeds a certain value, the optical sensor 5 opposes and outside surface member 9b with a high reflectance. In that state, output signal of the optical sensor 5 is turned on.

IPC: F01L13/00
Filed: 1990-09-26
Abstract: PURPOSE:To simplify structure as well as to get rid of any nonconformity such as the occurrence of operation failure due to air mixture into a hydraulic circuit by making a variable cylinder device composable by way of adding a second cam in addition to an ordinary valve driving cam. CONSTITUTION:At the time of usual operation of an engine, a cam 25 is at a standastill in an illustrated position, and a rocker arm 21 rockes with its one end 21b as a fulcrum point with rotation of a cam 24. Accordingly, a valve 14 opens or closes a passage 12 by doing the vertical motion. On the other hand, at time of low load operation, the cam 25 is rotated as far as about 180 deg. by a transfer shaft 26, and it is no longer driven by a second rocker arm 21 and the cam 24. At this time the rocker arm 21 is shifted downward with the one end 21b as the fulcrum point, so that the valve 14 separates from a valve seat 13. However, the valve 14 soon comes into contact with the valve seat 13 by dint of energizing force of a spring 19, whereby a piston 23 of a hydraulic lifter 22 is shifted downward, thus the passage 12 is fully closed and the cylinder converted is made into a nonoperative state.
