Title: Exhaust gas recirculation system for internal combustion engine
Inventor: SHIDA TOSHIMITSU
IPC: F02M25/07
Filed: 1991-01-25
Abstract: PURPOSE:To reduce the extent of heat load in an actuator as well as to make improvements in durability and reliability. CONSTITUTION:A temperature rise at the side of an actuator A is checked by a synergetic effect between radiation by means of a mounting seat (heat slinger) 12 extending sideward installed in the upper end of a body 8 and a radiation shielding action of radiant heat from the body 8, and in addition, since a clearance 18 is formed in a joint between the body 8 and the actuator A by means of a projection 14 on top of the body 18, a contact area with each other becomes lessened, and thus any possible heat conduction to the side of the actuator A from the body 8 is suppressed.

Title: Thermal head and its manufacture
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1990-02-02
Abstract: PURPOSE:To obtain a thermal head capable of reducing the printing energy, improving the thermal efficiency and making the apparatus compact by forming a glaze layer on an end part of an insulative substrate to be an inclined surface downwards towards the end of the insulative substrate, and making the other parts of the glaze layer to be horizontal, whereby a heat generating dot becomes good in touch with a heat sensitive recording member. CONSTITUTION:A glaze layer 2 is laminated on the whole surface of an insulative substrate 1 to form a glaze substrate 1A. The surface of the glaze layer 2 is made smooth. Thereafter, a layer 2A easy to be etched is formed on the surface of the glaze layer 2 with use of ion gas. Subsequently, a metallic layer 8 made of Al or the like is formed and a photoresist 9 is applied thereon to form a resist mask pattern 10. A V-groove is formed on the glaze layer 2 by etching the layer 2. The bottom of the V-groove reaches the insulative substrate 1. Then, by removing the photoresist 9, metallic layer 8 and layer 2A, the glaze substrate 1A is obtained. A pattern of each heat generating resis tance body 3 and electrode 4 is formed on the glaze substrate 1A from the surface of the glaze layer 2 to within the V-groove, which is coated with a protecting layer 5. Thus, the title thermal head is completed.

Title: Vertical double diffused mosfet
Inventor: SERATA TAKUJI
IPC: H01L29/78
Filed: 1990-02-02
Abstract: PURPOSE:To reduce a capacitance between a gate electrode and a drain electrode, to accelerate a switching speed and to reduce its loss by forming a conductive layer to form a Schottky junction with an epitaxial layer on the epitaxial layer of a first semiconductor layer having a first conductivity. CONSTITUTION:Since a fourth conductivity layer 31 is formed on an epitaxial layer 2 and a junction between the layers 2 and 31 is of a Schottky junction, a third depleted layer 23 extended vertically to the side of a semiconductor substrate 1 is formed in the layer 2 from the Schottky junction, and a fourth depleted layer 24 extended laterally to the lower part of a gate electrode 6 is formed. The layer 23 is not formed with an electrostatic capacitance between the electrode 6 and a drain electrode 10, but the layer 24 is formed with a capacitance between the electrodes 6 and 10, and has a larger thickness than that of a second deleted layer 22 as seen from a direction for connecting the electrode 6 to the electrode 10. Accordingly, the capacitance between the gate electrode and the drain electrode becomes remarkably small in value, is operated at a high speed, and its loss is small.

Title: Flame-resistant copper-clad laminated board
Inventor: SUZUKI TETSUAKI
IPC: B32B27/38
Filed: 1992-01-16
Abstract: PURPOSE:To improve electrolytic corrosion-resistant, enhance the reliability and correspond to packaging changed into high density by bringing a prepreg impregnated with an epoxy resin containing no halogen atom and dried into contact with a copper foil and using the whole or a part of the prepreg in a glass base material impregnated with an epoxy resin and dried. CONSTITUTION:A glass base material is impregnated with a low molecular- weight epoxy resin and dried and pretreated, and impregnated with an epoxy resin containing no halogen atom and dried, thus manufacturing a prepreg. The whole or a part of the prepreg may also be used in the prepreg, but the prepreg is brought into contact positively with a copper foil. Consequently, halogen and Na ions and Cl ions exerting an adverse effect are not brought near to the copper foil, thus preventing electrolytic corrosion. Accordingly, heat resistance is deteriorated, and heat resistance can be improved when a prepreg, in which the glass base material is impregnated with a halogenated epoxy resin and dried, is employed as a section not brought into contact with the copper foil as required.

Filed: 1988-02-04
Abstract: PURPOSE:To prevent the direct impact of a plunger and a core and to extend life by suppressing abrasion, by making the end surface of a yoke flush with that of the core and arranging a spacer so as to hold the same between said end surfaces and the end surfaces of both of the plunger and a side yoke. CONSTITUTION:At the time of the finish of printing, a plunger 3 is attracted to a permanent magnet by the finish of the supply of a current to an electromagnetic coil 2 and collides with a core 5 through a spacer 1 but, because of the spacer 1, the plunger 3 and the core 5 avoid direct collision to be kept from abrasion. The spacer 1 is also stretched between a side yoke 11 and a yoke 10 and, since the end surface 10a of the yoke 10 is made flush with the end surface 5a of the core 5, the attraction displacement of the plunger largely exerting effect on printing capacity is made stable.
