Title: Method for injecting hot-melt adhesive
Inventor: HAMA KOJI
IPC: B05D7/14
Filed: 1987-07-27
Abstract: PURPOSE:To enhance the adhesion and sealing property of a hot-melt adhesive and to facilitate the exchange of members by engaging an engaging member with the recessed groove of the member to be engaged, sealing the groove, and then injecting and charging the adhesive into the gap between both materials from an injection hole provided at the bottom of the recessed groove. CONSTITUTION:For example, when the reflecting mirror 1 of a head lamp for an automobile, etc., is engaged with a lens 4, the periphery 4a of the lens 4 is engaged with the recessed groove 2 formed on the periphery of the mirror 1, and the peripheries of both materials are fixed through a clamp 5. The hot- melt adhesive W is then injected and charged into the whole region of the gap 7 partitioned by the recessed groove 2 and the periphery 4a of the lens from the injection hole 6 formed in the bottom wall 2a of the recessed groove 2. As a result, a gap is not formed between the engaging members, and the good adhesion and sealing property can be kept at all times. In addition, since the hot-melt adhesive W is used, the reflecting mirror 1 or the lens 4 can be easily detached and exchanged.

Inventor: KURIHARA MASAYOSHI
IPC: B65D17/28
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent damages from occurring to a gilt layer and resin-coated layers while stably reducing force required for opening of a can by a method wherein opening notches each having the front-end radius in a specified value or below and the depth within a specified range are formed. SOLUTION: Opening notches 2a and 2b are formed respectively on the surface 1a and the reverse side 1b of a can lid 1 by means of mid-stop shearing with a set of mold composed of a punch, a die and a blank holder and by means of press molding executed afterward with a flash mold. Each of the opening notches 2a, 2b is formed in a sharp crevice-like incised groove with its front-end radius ρ being 0.025 mm or below and its depth D being within a range of 0.25 t to 0.4 t (t represents plate thickness), thereby reducing force required for opening the can. With a process without allowing the edge to be pressed against the can lid 1 employed, damages can be prevented from occurring to resin coating, and coating for repair becomes unnecessary.

Title: Piezoelectric device
Inventor: ANDO AKIRA
IPC: H03H9/25
Filed: 1989-07-17
Abstract: PURPOSE:To eliminate the effect of a bulk wave onto a surface acoustic wave element without decreasing the mechanical strength of a piezoelectric substrate by using a piezoelectric substrate comprising at least two parts whose propagation loss efficient of a surface acoustic wave element differs. CONSTITUTION:A piezoelectric substrate 12 has two parts 14, 16 with different propagation loss coefficient of a surface acoustic wave. The part 14 with a smaller propagation loss coefficient of the surface acoustic wave is arranged to one major face of the piezoelectric substrate 12 and the part 16 with a larger propagation loss coefficient of the surface acoustic wave is arranged to the other major face of the piezoelectric substrate 12. A weak bulk wave stimulated with the surface acoustic wave element is attenuated in the surface acoustic wave filter 10 when the wave passes through the part 16 with a larger propagation loss. Thus, the superimposition of the bulk wave onto the surface acoustic wave is prevented in the surface acoustic wave filter 10.

Filed: 1989-07-19
Abstract: PURPOSE:To easily confirm the discharge of static electricity by a user by displaying that static electricity is discharged by a discharge display means on the basis of the detection signal of a discharge detection means. CONSTITUTION:When a touch button 2 is pushed when a human body is charged in a car, a condenser 8c is charged and, thereafter, discharged voltage is applied to resistors 9b, 9c and comparators 9g, 9h. When static electricity is positive, an H-level signal is outputted when the voltage exceeds the reference potential Vr1 of the comparator 9g and, when static electricity is negative, the comparator 9h outputs an H-level signal. Therefore the input of an OR circuit 9i becomes an H-level in both cases and the output thereof is applied to a differentiation circuit 12 and an RSFF 14. Therefore, the output of an output terminal Q becomes an H-level and 'Static Electricity Charged has been discharged' is displayed by a display lamp 6.
