Title: Electronic component
Inventor: FUKUSHIMA TAKASHI
IPC: H01F17/06
Filed: 1990-11-19
Abstract: PURPOSE:To apply a transfer molding method, to avoid the influence of harmful matter, and to apply sufficiently soldering paste by arranging terminal members so as to be extended from the bottom of the electronic component to the top thereof along the surface of recessed case thereof to assemble a electronic component. CONSTITUTION:Since a terminal member 4 is extended from the bottom of an electronic component to the top thereof along the surface of a recessed case 1 so that a large area can be prepared for soldering, sufficient soldering paste can be applied, and further since a transfer molding method can be applied to assemble the electronic component, it is possible to reduce the production cost of the component. Furthermore, since a cover member 16 can, via a clearance 7, be mounted to a recessed case 1, even if harmful matter remains in the recessed case 1 when cleaning the electronic component, this harmful matter can be removed outside via the clearance 7.

Title: Seal image processor
Inventor: SHIBATA TOSHIE
IPC: G06T1/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To reduce the burden on an operator and also to shorten the waiting time for a person who applies for registration of his/her seal by collectively removing the trash images existing around a seal impression image without using a trash removing tool, etc. SOLUTION: The shape of an image segmentation area 14 is manually selected according to the shape of a seal impression to be registered.

Title: Laser marking device
Inventor: KOSEKI RYOJI
IPC: B23K26/00
Filed: 1991-10-31
Abstract: PURPOSE:To miniaturize the entire laser marking device when compared with conventional ones by providing plural discharge electrodes in one gas chamber and making respective discharge electrodes independently irradiate laser beam. CONSTITUTION:Respective switch means 30 irradiate laser beam from respective discharge space 13 by way of a front mirror according to open/close control. However, since an RF power source 31 is shared, laser beam is sequentially irradiated in time-division manner from respective discharge space 13 and a sensor confirms that. Respective electrodes 11 and 12 are heated due to irradiation and the gas in the respective discharge space 13 degrades. However, the electrodes 11 and 12 are cooled with cooling water running through cooling water passages 21 and 22. Respective discharge spaces 13 are dispersion-cooled and the non-degraded gas within a gas chamber 1 is supplied to the discharge space 13 through cooling holes 23. Therefore, a plurality of second electrodes 12 are laminated each other in one gas chamber and, since front and rear mirrors 24 are shared with plural discharge space for respective second and first electrodes 12 and 11, the entire device can be miniaturized.

Abstract: PURPOSE:To make a caution with an easy-to-see display for a burn by a method wherein a burn caution displaying means for applying the burn caution to a user through a liquid crystal display when a heating means is in its hot temperature, and a liquid crystal driving means for controlling a display of the burn caution displaying means are provided. CONSTITUTION:Since a heater 11a is kept at its hot condition after its heating and cooking operation, if a person accidentally touches the heater 11a, a burn might occur to the user. In this case, a controlling means 12 may output a signal also to a hot temperature sensing means 15 at the time when a control signal for terminating an energization for the heater 11a is outputted. A signal is also outputted to a hot temperature sensing means 15. The hot temperature sensing means 15 may detect a termination of energization for the heater 11a in reference to this signal. Termination or energization is detected such that a hot temperature condition of the heater 11a is detected by the hot temperature sensing means 15 while the heater 11a is normally kept at its hot temperature condition. A burn caution displaying means 13 is driven by the liquid crystal driving means 14. The user may know easily the hot temperature condition of the heater means 11 through 'caution of burn' of a burn caution display means 13, resulting in that the user may pay attention not to contact with the hot temperature part.

Title: Fluid control valve having closing function
Inventor: ITOI TAKESHI
IPC: F16K1/26
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent generation of wear or fine damages to a valve by providing a small projecting part on a vertically movable valve formed of a soft material within a holder filled with the liquid between an inlet and an outlet of the fluid, and closing the valve by allowing the projecting part to abut on an opposite seal part consisting of a hard material. SOLUTION: A soft material such as Teflon is used for a valve 4, and a hard material such as a metal is used for an opposite seal part 7, a small projecting part 5 consisting of a soft material is provided on the valve 4 to shut off the fluid 3. Because the small projecting part 5 is not formed of a hard material, the share by vertically opening/closing the valve can be remarkably reduced, and the wear resistance can be improved. Also, because the projecting part 5 of the soft material is provided on the valve 4, the pressure caused by the vertical movement can be absorbed, fine cutting scrap caused through biting and pigment particles generated by damages do not coagulated nor grow, and the coagulates can be prevented from being dropped due to the liquid flow, and defective foreign matters in the coated film can be prevented.
