Title: Noise suppression structure of power supply equipment
Inventor: GEKITO MASAKAZU
IPC: H02M1/00
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To suppress noise without increasing the size and cost of a power supply equipment by making an insulating sheet interposed between a semiconductor switching element and a heat radiation fin from the material having a low permittivity and a high dielectric loss. SOLUTION: An insulating sheet 51 interposed between a semiconductor switching element 1 and a heat radiation fin 2 is made of the material having a low permittivity and a high dielectric loss. The permittivity of the insulating sheet 51 forms parasitic capacitance, however, the low permittivity hardly allows high frequency current to flow and the high dielectric loss increases the resistance against current, In other words, the insulating sheet 51 can be deemed as a series circuit of a capacitor and a resistor. When the semiconductor switching element 1 makes an on and off operation, there is a potential difference generated between the semiconductor switching element 1 and the heat radiation fin 2, and noise current is caused to flow through the insulating sheet 51, the parasitic capacitance 511, and the resistor 512.  However, the noise current is consumed as heat by the resistor 512 and thereby it can be reduced.

Title: Automatic focus adjustment device
Inventor: MATSUMOTO TOSHIYUKI
IPC: G02B7/28
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To facilitate focusing for a moving subject, and to eliminate hunting of a photographing lens relating to a stationary subject. SOLUTION: Imaging positions of a pair of subject images are detected repeated by a focus detecting part 2, and information as to a focus adjustment condition of a photographing lens with respect to a subject is output in a time series by a moving body predicting part 1. Whether the subject is a moving body or a stationary body is determined by a moving body determining part 7 based on the time-serial output of the focus detecting part 2. A determination value for the moving body and a determination value for the stationary body are set respectively for focusing determination in response to a determined result therein. The output of the focus detecting part 2 is compared with the determination values by a focusing determining part 6 to determine whether the photographing lens is focused to the subject or not.  When that the photographing lens is not focused with respect to the subject is determined by the determining part 6, a lens driving amount required for focusing the photographing lens is computed by a correlation operation part 5 to drive the photographing lens in response to the lens driving amount.

Title: Loud speaker cable connecting terminal
Inventor: ASAMI HIDEJI
IPC: H01R4/48
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a loud speaker cable connecting terminal which can supply the mechanical strength, while exercising superior electric acoustical characteristic of a soft metal such as a pure silver at the maximum level, can use a pure silver not only to a cable but also to a terminal, thereby enabling exercise of the superior electric acoustical property of the pure sliver. SOLUTION: A conductive part 21 consists of a soft metal with a superior electroacoustical characteristic, and a cable crimp mechanism is to use the fastening of a screw 1a and the pressing by a spring 13 concurrently. The cable crimp mechanism has a structure such that it does not allow application of a shearing force by the spring 13 to a cable. Even though the soft metal with superior electroacoustical characteristic generates a creep, the reduction in the crimping force is suppressed by the pressing by the spring 13, so as to maintain a good contact condition.
