Patent JP-S63194424-A (JP)
Title: Antenna circuit
Inventor: IRIE MICHIO
IPC: H04N5/44
Filed: 1987-02-09
Abstract: PURPOSE:To improve the efficiency of an antenna and the sensitivity of reception, by inserting a balancing circuit/unbalancing circuit converter between the antenna of a portable radio equipment and a transmission circuit or a reception circuit. CONSTITUTION:A balloon (the balancing circuit/unbalancing circuit converter) 9 is inserted between the antenna 1 and the transmission circuit or reception circuit 2. Since the winding 11b of the balloon 9 performs the function of a choke coil which represents high impedance for the in-phase component of a high frequency current, the loop of the in-phase component is cut off, and potential generated by ground impedance disappears. The receiver of the portable radio equipment is also constituted in a similar way. Even when the portable radio equipment is miniaturized, and a grounding area is decreased, and the ground impedance is increased, no potential is generated by the ground impedance. Therefore, unrequired radiation is reduced in a transmitter, and noise picked up by the ground impedance can be remarkably reduced, and impedance matching between the antenna and the reception circuit can be improved in the receiver.

Title: Camera
Inventor: HORIMA KATSUTOSHI
IPC: G03B17/28
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To stabilize the size of a photographic image plane in spite of the zooming state of a photographing lens by forming a rib-like projection part projected to a film side and positioned in the vicinity of the aperture opening in a film feeding direction on the inner surface on the aperture opening side of a film feeding path. SOLUTION: The ribs 2a extended in an up-and-down direction and projected to a pressing plate side are formed on both right and left sides of the aperture opening in a camera main body 2. A cartridge chamber 2c in which a film cartridge is loaded is formed on the right side of the camera main body 2. In such a case, if the rib 2a is not formed, a light beam whose emitting angle is large forms an image at a 3rd position on a film surface, and a difference from the 1st position becomes large. However, since this camera is provided with the rib 2a, an image plane end is fixed at a 2nd position whose difference from the 1st position is small. By providing the rib 2a in such a way, the dispersion of photographic image plane size in the case of telephotographing or wide- angle photographing is restrained, and the image plane size is stabilized.

Filed: 1989-02-07
Abstract: PURPOSE:To make the device effectively exhibit vibration isolation effect by providing a balance rod extended from a piston member so as to be slidable on the other blockading wall of the device main body and penetrate it fluid tightly. CONSTITUTION:A working rod 44 is extended from a piston 28 partitioning a cylinder chamber 24 into two fluid chambers 30, 32.

Title: Wire attachment abnormality detection device for pressure contact joint connector
Inventor: OKURA YOSHIO
IPC: H01R4/24
Filed: 1995-01-24
Abstract: PURPOSE: To detect abnormality in attachment of wire at the time of cover installation. CONSTITUTION: When a wire Wf is installed astride two pressure contact grooves, the wire Wf gets on pressure contact groove opening face 11 of a case. When a cover push member 44 pushes down a cover 30, a check pin 60 moving down together with the cover push member 44 hits the wire Wf midway, so that its further downward movement is hindered. Then, along with move- down of the cover push member 44, the check pin 60 moves up relative to the cover push member 44, so that both contact portions 61L, 61U get away from both electrode portions 56L, 56U and thus continuity between both electrode portion 56L, 56U is broken. This state is then detected by continuity test circuit 64 and thus attachment abnormality of wire Wf is detected.

Title: Load regulator for rotary body
Inventor: HASHIZUME HIROSHI
IPC: H02K7/10
Filed: 1983-02-22
Abstract: PURPOSE:To stabilize torque by providing weights, which are brought in frictional contact with a fixed body by means of a spring, on a rotary shaft, allowing said weights to move by means of the centrifugal force resulting from the rotation, and making the frictional force variable, in the load regulator of a rotary body having torque characteristics similar to a motor. CONSTITUTION:When a rotary shaft 11 rotates, weights 14 also rotate through a rod 13 provided in an integrated form with the shaft 12, allowing centrifugal force to be applied to the weights 14. On the other hand, since spring force 15 is being applied to the weights 14, a frictional force corresponding to the difference between the centrifugal force and the spring force 15 is applied between a fixed outer surface 16a and the weights 14. Accordingly, a load torque just as inversely proportional to the rotating speed of the shaft of the rotary body is generated, making constant the apparent output torque of a rotary body having load characteristics of a motor, etc. and, thereby, stabilizing the torque.
