Title: Color picture processor
Inventor: NAKA TOSHIYA
IPC: H04N1/40
Filed: 1989-04-07
Abstract: PURPOSE:To keep the picture quality of an output picture in a certain or higher level regardless of the secular change of a recording medium of a picture output means by detecting the test pattern outputted from a pattern generating means and correcting the degradation in characteristic of the whole of a picture system by a correcting means. CONSTITUTION:The original picture inputted from a picture input part 21 like an image scanner or a CCD camera is subjected to gamma correction in a picture processing part 22 and is outputted from a picture output part 24. A pattern generating part 25 is provided which generates the test pattern for the purpose of detecting the secular change of the recording medium, and the test pattern outputted from the pattern generating part 25 is temporarily printed by a picture output part 24, and printed results are read again by the picture input part 21, and output data Dn of the pattern generating part 25 and output data D'n from the picture input part 21 are compared with each other by a correcting part 26 to correct they characteristic of the picture processing part 22. Thus, the secular change of the recording medium of the output device is compensated to always keep the output picture in a certain or higher picture quality level.

Title: Signal processing system
Inventor: MATSUMOTO MIKIO
IPC: G01C1/00
Filed: 1981-06-10
Abstract: PURPOSE:To make smaller the minimum detection width without damaging S/N by detecting the maximum value of differential wave form of a detection signal at the end of an object and shaping the wave form and detecting the end of the object after resetting differential wave form. CONSTITUTION:When infrared light input is given to a infrared detector 201, its output is passd through an equalizer 20 and led to differentiator 203 that consists of a resistor 203, condenser 203 and switch 203. With input of wave forms to positive and negative peak positions detection circuits 205 and 206 that are connected to a buffer amplifier 204, pulses are generated at positive and negative peak positions. Those pulses are input to a peak reset pulse generating device 207, and changed further into shorter pulses and close switch SW 203 during this time. Then, the charge of the condenser C203 is instantaneously discharged, which rapidly reduces the output of an amplifier 204, and its wave form is added to a wave form shaping circuit 208 to shape the wave form.

Title: Power output circuit
Inventor: NUNOKAWA YASUHIRO
IPC: H03K17/06
Filed: 1988-04-13
Abstract: PURPOSE:To speed up the switching of an output MOSFET to an off state by providing driving MOSFET between the gate and the source of the output MOSFET in a source follower type so as to attain switch control. CONSTITUTION:The driving MOSFETQ2 is provided between the gate and the source of the power output MOSFETQ1. When a control signal is switched from an H level to an L level, the output signal of an inverter circuit N1 comes to the H level and makes FETQ2 in an on state. Since the gate and the source in FETQ1 are shortened, FETQ1 is switched from the on-state to the off-state. At that time, a back electromotive voltage occurs in an inductive load L and an output terminal OUT connected to the source of FETQ1 is reduced to a negative and lower order. Energy accumulated in a load L can be released in a short time by a voltage clamping circuit consisting of a diode D3 and a Zener diode ZD.

Title: Nut, particularly wheel nut
Inventor: EEBUARUTO BEHIRE
IPC: F16B39/36
Filed: 1993-04-16
Abstract: PURPOSE: To improve a contact condition between a member, to which a nut is tightened, and a pressure washer, thereby to provide a uniform distribution of a contact pressure by manufacturing the pressure washer through the massive forming method so as to give a concave contact zone. CONSTITUTION: This nut is an integrally formed pressure washer having a concave contact surface 4a. In this case, the pressure washer is manufactured by the massive forming method. When the nut is tightened, it is necessary to reduce the axial clearance between the pressure washer and the corresponding surface from the start of the contact of the outside diameter of the pressure washer until the complete contact of the pressure washer. Therefore, uneven tightening force is compensated by elastic deformation of the pressure washer due to further tightening of the pressure washer.

After the support member 33 continues its movement, it is  moved downwardly to reach a carrying-out conveyor 40. In this position, the inner container 12 is now placed  on the conveyor 40 and the support springs 34 are retracted again and disengaged from the inner container 12  so that the inner container 12 is left on the conveyor 40. A predetermined number of inner containers 12 are  accumulated on the conveyor 40 by a repetition of such a sequence of operations. Thus, the efficiency to  accumulate and separate inner containers 12 can be improved thereby.
