Abstract: PURPOSE:To improve the joint strength without processing a pipe member and obtain a bicycle frame having the excellent safety and reliability by locating a shape memory ring at a joint part of a pipe material and a lug material, and heating both materials to be fixed. CONSTITUTION:A lug 1 is precisely casted in a lost wax process, etc., and an external thread part 1a is formed in the tip thereof. A one directional shape memory ring 3 in which an internal thread 3a is processed is previously inserted into a pipe 2, and thereafter, the ring is heated to be enlarged and is integrated with the pipe 2 by the generation of a large frictional force. Thereafter, the adhesive is coated on a joint part of the lug 1 and the pipe 2 to join both, and the adhesive is heated to be hardened in a constant temperature bath. With this structure, a mechanical joint is possible without the conventional thread processing and rivet hole processing to the pipe 2, and the generation of the stress concentration can be prevented, and a bicycle frame having the high safety and the high reliability can be obtained.

Title: On-vehicle speaker device
Inventor: KAMATA JUNICHI
IPC: H04R1/02
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the occurrences of a rattle sound and distortion by providing a means impressing a DC signal to correct the displacement of the diaphragm of a speaker unit in addition to a voice signal to be impressed to the speaker unit. CONSTITUTION:When the voice signal is impressed to a terminal 24, a first and a second amplifiers 26, 28 operate in inverse phases each other, and act as a well-known BTL amplifier and drive the speaker unit. Additionally, when a DC correction signal is impressed to an input terminal 31, the signal undergoes a buffer amplifier 30 similar to the case of the voice signal, the signal is inputted to the first and the second amplifiers 26, 28 in inverse-phase relation, hence the voice coil of the speaker unit 10 is driven to shift in one direction. Therefore, the inclination of the diaphragm to shift toward the outside of the vehicle on account of a pressure down in a duct as the vehicle runs, can be corrected in the effect of the correction signal impressed to the terminal 31.

IPC: G03B13/12
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To confirm an operability and a zooming effect in a satisfactory state, as for a camera capable of pseudo-zoom photographing. SOLUTION: By operating a zoom lever, the magnification of a finder is varied between the minimum finder magnification α=1 capable of observing a photographing range corresponding to the shortest focal distance f1 of a photographic zoom lens and the maximum finder magnification α=4 capable of observing the photographing range corresponding to a pseudo longest focal distance which is obtained by multiplying the longest focal distance f2 by the maximum value of the pseudo zoom magnification. The real focal distance of the photographic zoom lens and the pseudo zoom magnification β are decided by a controller in accordance with the finder magnification α.  In the case the finder magnification α is within the extent of 1 to 2, the real focal distance of the photographic zoom lens is controlled so as to correspond to the finder magnification α within the extent of the shortest focal distance f1 and the longest focal distance f2, and also, the pseudo zoom magnification β is controlled to be '1' which shows that the pseudo zoom photographing is not executed. In the case the finder magnification a becomes >2, the photographic zoom lens is fixed at the longest focal distance, and the pseudo zoom magnification β is decided by satisfying α=(f2/f1).β.

Filed: 1984-03-07
Abstract: PURPOSE:To eliminate the need for a preionizing circuit by a method wherein an inductance circuit, resistance circuit, and a preionizing arc discharge gap circuit are connected to the free terminal of a capacitor arranged in parallel with a switching circuit. CONSTITUTION:To the free terminal 10 of a capacitor 7 positioned in parallel with a switching circuit 13, a circuit 18, which is either an inductance or a resistance or a combination of the two, and a preionizing arc discharge gap 3 formed between preionizing electrodes 4, 5 are connected. With the circuit constituted as such, an arc is generated across the gap 3 when a passage is established through the switching circuit 13. The ultraviolet rays generated by the arc throw the laser gas into preionization. The electric potential across the discharge electrodes 1, 2 is then twice the voltage at a high-tension power source 16. Accordingly, a pulse gas laser device, incorporating this LC inversion type exciting circuit wherein preionization is automatically triggered off by ultraviolet beams, does not require a separately installed preionizing circuit.
