Title: High pressure-proofing can lid and production thereof
Inventor: HANABUSA YASUHIRO
IPC: B21D51/44
Filed: 1993-09-06
Abstract: PURPOSE:To prevent a can from being buckled even when the inner pressure in the can increases, by bending a counter sink both inward and outward in the axial direction of the panel. CONSTITUTION:A high pressure proofing can lid is provided with an almost disk-formed panel 2 and a counter sink 3 having a U-shaped cross section, formed along the external periphery of the panel 2. The counter sink 3 is bent both inward and outward in the axial direction of the panel 2. Since the counter sink is bent in this way, the pressure proof strength of the counter sink 3 against the inner pressure of the can is increased. Accordingly, when the contents of can is a carbonated drink, even if the temperature in the can rises up abnormally and hence, the pressure in the can unusually increases because it has been left in a car or the like in summer, the counter sink 3 is hardly deformed. Thereby, buckling is hardly caused and as a result, inconveniences like breakage at scores can be reduced.

It is desirable for the inner heat rays absorbing plate to have optical property which practically transmits effective wavelength components in the heat rays for heating, or optical property which absorbs heat rays for heating and converts the rays into secondary heat rays.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To exactly detect the life of a sealed lead storage battery by accurately estimating the discharge capacity of the battery without being influenced by a ripple voltage or temperatures. SOLUTION: An A.C. of a constant frequency is supplied to a battery 1 to be measured from an A. C. feed part 2 for a predetermined time. Only an A.C. voltage component of the same frequency as that of the A.C. is detected from a terminal voltage of the battery 1 and amplified at an A.C. voltage amplification part 4. A voltage response waveform output from the amplification part 4 is Fourier-transformed at an impedance calculation part 11, thereby, an amplitude of the A.C. voltage component of the same frequency as that of the supplied current is detected. Impedance value of the battery is calculated from the amplitude. A D.C. voltage and a surrounding temperature of the battery 1 when the battery 1 is discharged through a discharge load resistor 5 for a predetermined time are measured.  The discharge capacity is estimated by a capacity estimation part 12 on the basis of values obtained by correcting, with the surrounding temperature of the battery, the impedance value of the battery 1 and the voltage of the battery after discharged for the predetermined time to detect the life of the battery.

IPC: H01L21/60
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent a bond from creeping up and sticking to a suction tool in thermocompression bonding. SOLUTION: A supply and a take-up reel of an adhesion preventive tape 13 for preventing sticking of a bond 16 to a pressure bonding head of a mounting equipment for an electronic component 6 are installed. When mounting an electronic component 6 on a substrate 5 with a bond, a suction tool 20 is allowed to suck the electronic component 6 through interposing the adhesion preventive tape 13. The bond 16 which has its viscosity now decreased from the heating conducted and when thermocompression bonding the electronic component 6 creeps up the side faces of the electronic component 6. However it is possible to prevent the bond 16 from sticking to the lower face of the suction tool 20 due to the existence of the adhesion preventive tape 13. Consequently, the suction of the electronic component 6 by the suction tool is not disturbed by adhered and hardened bond. Furthermore, the maintenance and cleaning work of the suction tool 20 can be reduced.

Abstract: PURPOSE:To economize the electric power and the number of ICs, by using one buffer as an error correction buffer as well as a data buffer and using it as the data buffer normally and using it as the error correcting buffer if an error occurs. CONSTITUTION:Normally, changeover switches 10, 11, and 12 are switched to a side A by a control line so that a data/error correction buffer 14 is used as the data buffer. In case of error, data from the sense output is inputted to an error correction circuit 16, and it is checked whether data has an error or not.

IPC: G02B27/40
Filed: 1985-10-09
Abstract: PURPOSE:To obtain simple and low-priced constitution of the device by shifting freely plural transparent bodies with the different refraction index arranged between the optical lens and the focusing surface, in the orthogonal direction of the optical axis in the attitude to interrupt the optical axis. CONSTITUTION:When a groove-shaped scratch 2 is provided at a commodity 1 and the refraction index of a transparent body 4 is selected so that the scratch 2 can be located in the rear direction of the focusing position of an optical lens 3, the light irradiated to the groove surface of the scratch 2 can be visually confirmed in the bright condition. When the refraction index of the transparent body 4 is selected so that the scratch 2 can be located in the front direction from the focusing position of the optical lens 3, the shadow is formed on the groove surface of the scratch 2, and therefore, visual confirmation can be darkly executed. For such a reason, when the transparent body 4 with the different refraction index is successively shifted, the brightness and the darkness of the reflecting light can be visually confirmed continuously. The large-scaled device is not necessary, low-priced and mass-production can be executed.
