Title: Film winding device
Inventor: KOBAYASHI KAZUNARI
IPC: G03B17/00
Filed: 1983-06-15
Abstract: PURPOSE:To detect surely a small hole by subjecting a surface part, which faces a photocoupler, around the small hole of an operating body with a non-reflective processing. CONSTITUTION:The rotation of a winding motor 33 is decelerated and is transmitted to a winding shaft 31 having a winding pawl 14 through a gear train 32 consisting of plural spur gears to drive a winding part 4 of a film cassette 3. A gear 34 of the gear train 32 is so constituted that it is rotated once in accordance with feeding of one frame, and a long hole 35 is provided as the small hole in the peripheral part. A photocoupler 36 is provided in the position which the long hole 35 passes through the gear 34 is rotated, and the photocoupler 36 detects one rotation of the gear 34 to stop the rotation of the winding motor 31. The surface part around the long hole 35 is colored black, and reflection is suppressed by this colored part 40 to increase a difference between the output of the photocoupler in the position of the long hole 35 and the output on the surface other than the long hole 35. Consequently, detection of the long hole 35 is stabilized and assured.

Filed: 1992-04-27
Abstract: PURPOSE:To read data from a memory constituted of a dynamic random access memory at a high speed without a delay by refresh operation. CONSTITUTION:According to access demand from a CPU 1, by a memory controller 2, a read control signal is outputted to memory banks 3-6 in accordance with the access content. The memory bank immediately after ending read operation is refreshed by a refresh controller 7 at any earlier time of an access demand time to other memory bank or the maximum refresh time of the memory bank. The maximum refresh time of respective memory banks 3-6 is decided by refresh timers 8-11. Thus, competition between the access demand and the refresh operation is decreased and a memory device readable at high speed is realized.

Title: Hold distortion compensating circuit
Inventor: TAKADA KAZUHISA
IPC: H03M1/12
Filed: 1992-04-27
Abstract: PURPOSE:To reduce error components of a pulse adder type switching noise compensating circuit. CONSTITUTION:The voltage, which is proportional to an input voltage difference, is held by a holding circuit 5, during a short duration right after the completion of a hold period and a pulse generating circuit 7 outputs pulses, whose wave height values are proportional to the output of the circuit 5, for the same duration as the hold period. These output pulses are added with the outputs of a hold circuit 3 and the low frequency components of distortion are reduced. When the input output voltage difference of the circuit 3 is small, error components caused by noises are outputted from a differential amplifier 4. These small error components are inputted to a nonlinear differential amplifier 6. The amplifier 6 is made to have a characteristic so that there is no output when the input is close to zero, sets the level of a non-sensitive region to be slightly wider than the error component level which is generated by noises so that pulse adding portion of errors is eliminated.

Title: Solid state pickup device
Inventor: WADA TAKAMICHI
IPC: H04N5/335
Filed: 1980-08-04
Abstract: PURPOSE:To apply a TV on the market to a meter panel monitor camera scarecely requiring motion in particular, by securing a sufficiently long interval of charging for a diode. CONSTITUTION:A power source is connected to a terminal 37 of the picture element, and the drive clock is applied to terminals 39 and 36 respectively. With application of the pulse to the terminal 39, a photodiode 16 is charged. When the light is irradiated to the diode 16, the signal charge is stored to the diode 16 to reduce the potential of the diode 16. The reading scan of the optical signal is carried out in the pulse timing of the drive clock; while the diode 16 is charged in the pulse timing of the drive clock having an independent period from the reading period. Thus the light integrating time is increased.

Filed: 1989-04-28
Abstract: PURPOSE:To discover the misregistration of a detector by providing a 2nd control means which stops a motor as well as outputs an accident detection signal in response to a deciding means having decided that the movement amount measured by a measuring means prior to the detection signal being output from a 2nd detector reaches a standard distance. CONSTITUTION:In the case of the measured movement amount by a measuring means 5 having reached a standard distance prior to a detection signal being output from a 2nd detector 4, the processing of motor 3 stoppage, etc., are taken by judging as the accident of the 2nd detector 4 or its circumferential position. The safety at the abnormality generation time can thus be secured. Also at the normal time when a detection signal is output from the 2nd detector 4 prior to the measured movement amount by the measuring means 5 reaching a standard distance, the measured movement amount is stored. Since this measured movement amount is equivalent to the distance between the position of the 2nd detector 5 and a 1st detector 6, the misregistration of the setting positions of these detectors is known in advance and the accident due to this misregistration can be prevented.

Abstract: PURPOSE:To obtain a cold rolled steel plate of about 40-55kg/mm.<2> tensile strengths having a high (r) value and quench hardenability by performing annealing after hot rolling and cold rolling of Al killed steel of an increased content of Si in a batch tupe annealing furnace. CONSTITUTION:Steel consisting of 0.005-0.02 C by %, 1.0-2.0 Si, 0.03-0.5 Mn, <=0.1 P, 0.02-0.08 Al, 0.002-0.020 N and the balance Fe and unavoidable impurities is hot rolled, and after it is coiled at below 600 deg.C, it is cold rolled. The resultant steel plate is annealed in a continuous heat treatment furnace in coil units such as an open coil or tight coil type box annealing furnace. Here, below the lower limit of C, quench hardenability is low. If Si is below the lower limit, the strength of levels cannot be obtained and the effect that it gives on the quench hardenability is less. In excess of the upper limit, an (r) value decreases considerably; at the same time, crystal grains coarsen, resulting in an increased rate of surface roughening. If the Mn exceeds the upper limit, the (r) value decreases considerably.
