Title: Film wind-on apparatus for camera
Inventor: OGIHARA MASUO
IPC: G03B1/60
Filed: 1992-12-24
Abstract: A film wind-on apparatus for camera includes a d-c brush motor the movement of which is controlled by monitoring the brush noise of the motor using an amplifier 6 and comparator 7. The control circuit 13 reads the number of film frames already wound up and on the basis of the monitored noise, further reads the data stored in the EEP ROM 12 indicative of the amount of rotation of the direct current brush motor 2 required to wind up by one frame stored in the EEP ROM 12; rotates the direct current brush motor 2; has access to the EEP ROM 12 on the basis of the detected ambient temperature and battery voltage and the previously read data indicative of the amount of film wound up, in order to read the timing (the number of pulses) at which the direct current brush motor 2 is braked; and when the counter 8 counts up the read number of pulses, applies a brake to the motor 2 to stop it. An alarm 15 sounds if the film is loaded in error. <IMAGE>

Title: Rotation transmission change-over mechanism for tape drive apparatus
Inventor: YOSHIMURA TOSHIO
IPC: G11B15/44
Filed: 1994-01-06
Abstract: A rotary force of a drive motor is transmitted to primary drive members (19a, 19b). Upon a change-over in the direction of rotation of the motor, a partially-detoothed gear (25) is brought by frictionally-driven gearing (30, 31; fig 3) from a neutral position into meshing engagement with a middle gear (28) and a drive gear (20) and the rotary force of the motor is transmitted via these gears to an arcuate rack (22b) provided on a turnable plate (22). The plate (22) carries a member (21) which, when the plate turns about pin (23) transmits rotation from member (19a or 19b) to member (14a or 14b) attached to a reel hub. When the meshing engagement between the middle gear and the partially-detoothed bear is released, the turnable plate is held at a turned position by an over-center spring (34). The gear (25) may alternatively mesh directly with the arcuate rack (22b). <IMAGE>

Title: Image reject mixer
Inventor: SOUETINOV VIATCHESLAV IGOR
IPC: H03D7/12
Filed: 1997-01-11
Abstract: Circuit 200 comprises an input amplifier stage 290, phase-splitters 292, 293 and mixer cores 294, 295. An input signal is applied to terminal 220, a local oscillator signal applied to terminals 230, 231 and a 90 shifted local oscillator signal is applied to terminals 232, 233. The In-phase differential signal is output at terminals 240, 241 and the quadrature signal is output at terminals 242, 243. Phase-splitters 292, 293 comprise base-coupled transistors 202, 203, 205, 206 which are biased by a potential applied to terminal 262. As these phase-splitters are driven by input amplifier stage 290, which acts as a current source, the arrangement has very good noise properties. Degeneration inductor 280 reduces the noise figure of the circuit further because it is a noiseless component. Phase-splitters 292, 293 and mixer cores 294, 295 are preferably cross-coupled to allow cancellation in phase-splitters 292, 293 of the second harmonic of the local oscillator signal generated at the inputs to mixer cores 294, 295. The outputs of mixer core 295 are phase shifted by 90 and combined with outputs of mixer core 294 for image signal rejection.
