Title: Ignition plug with purging function
Inventor: MASUTANI KEISUKE
IPC: H01T13/14
Filed: 1993-06-30
Abstract: PURPOSE:To enhance the ignitability with an ignition plug of a fuel direct injection type engine of an airplane, ship, car, etc., by purging the deposited carbon or uncombusted substance attached to the electrode by the use of the air. CONSTITUTION:The body 8 of an ignition plug is equipped with a positive electrode 1 and negative electrode 2, and the power is supplied from a power supply 13 through terminals 6, 7. When the ignitability of the electrodes 1, 2 worsens, a compressed air is introduced from an air purge introducing hole 3, and this air passes a check valve 4, passage 9, and air conduits 5 to be jetted from a plurality of air jets 5b opened at the periphery of the electrodes 1, 2. The deposited carbon and/or uncombusted substance attached to the electrodes 1, 2 are purged with this air jet, which improves the ignitability of the ignition plug.

IPC: H01L23/28
Filed: 1995-06-28
Abstract: PURPOSE: To reduce strain of a solder junction part caused by heat deformation by forming an outer terminal of a conductive material in a hole formed ranging from a package surface to an opposite surface of a surface facing a semiconductor element of an inner lead and exposing a part thereof to an outside of a package. CONSTITUTION: Spheric outer terminals 2a to 2c are formed in an opposite surface of an adhesion surface of inner leads 3a to 3c. The outer terminals 2a to 2c are partially provided to an inside of outer terminal holes 8a to 8c provided to resin 6 and is exposed to an outside of a package. Since solder is used for a material of the outer terminals 2a to 2c, they can be directly connected to the inner leads 3a to 3c and an electrode of a printed board. It is practical to electrically connect the inner leads 3a to 3c and the outer terminals 2a to 2c one to one. It is desirable to use Pb/Sn type eutectic solder which is widely used for mounting of a surface mounting type semiconductor device for a material of solder.

IPC: B41J13/02
Filed: 1983-09-07
Abstract: PURPOSE:To prevent noise from being generated, by a method wherein a sound- insulating block is brought into contact with a paper guide surface through a printing paper at a position where a lail with roller is brought into contact with a recording paper feeding roller through the printing paper by a printing operation, thereby closing a fitting-in port. CONSTITUTION:When the printing paper 25 is fitted in through the fitting-in port 32a and a change-over lever 13 is changed over from a position A to a position B, the first operating arm 18 is turned leftward together with the second operating arm 19 by the weight of the paper press roller 22 and the like and a tension spring 20, the roller 22 is brought into contact with a paper-feeding roller 24 through the paper 25, thereafter the sound-insulating block 28 presses the paper 25 against the paper guide surface 32b by a weak compression spring 31, and closes the port 32a. When the lever 13 is changed over from the position B (suitable for using a continuous paper) to a position C, a condition suitable for frictional feeding by a tractor is obtained. Accordingly, clattering sound of the printing paper is prevented from being generated due to repeated impacts, and noise can be prevented from leaking.

IPC: F16K3/314
Filed: 1994-06-10
Abstract: PURPOSE:To improve the responsiveness by forming a rotary shaft of a large diametric lower cylindrical part and a small diametric upper cylindrical part, and forming a sloped surface or curved surface, symmetric shaped relating to a center axial line to have centripetal action, between the lower cylindrical part upper end surface and a head case ceiling wall internal peripheral surface connected thereto. CONSTITUTION:A rotary shaft 29 comprises an upper cylindrical part 39 of small diameter and a lower cylindrical part 40 of large diameter. By up/down operation and turning operation of a handle lever, a delivery flow amount and mixed water temperature are controlled. In the case of this handle operation, in the rotary shaft 29, a tapered surface 67 of the lower cylindrical part 40 and a tapered surface 68 in a ceiling wall of a head case 27 are always closely connected, to form no slight clearance therebetween. Consequently, operating force of the handle lever is immediately transmitted, without causing any time lag, to a movable disk valve element 31 through a lever shaft 28 and a disk cap 30, to prevent a play and chattering from being generated in the handle operation. Accordingly the responsiveness and an operating have extremely been improved.
