Title: Differentiating circuit of mangetic disk device
Inventor: AIKAWA TAKASHI
IPC: G11B20/14
Filed: 1980-12-03
Abstract: PURPOSE:To prevent the generation of an error pulse by making an outer-side differential waveform closer to an innerside differential waveform by varying  the bias point of differentiating operation corresponding to the track position of  a magnetic disk. CONSTITUTION:A signal read from a magnetic disk is inputted to a peak detecting circuit 4 through an amplifier 1, a filter 2, and a differentiating circuit 3' and the bias point of the transistor TR of the circuit 3' is varied by a track counter 5, a D/A coverter 6 and a coil L. Namely, the counter 5 indicates the track position of the magnetic disk from which the information is read, and its count value is converted into an analog voltage by a D/A converter 6. Therefore, the analog voltage is applied to the base of the transistor TR through the  coil L, so its base potential varies with the count value of the track counter 5.

Title: Automatic inspecting apparatus for strip-shaped body
Inventor: MATSUBARA TOSHIRO
IPC: B65H26/02
Filed: 1989-07-03
Abstract: PURPOSE:To recognize a frame having a defect with the naked eyes by forming a mark which can be recognized with the naked eyes on the frame wherein the defect is detected, and by only viewing a strip shaped body whose inspection is finished. CONSTITUTION:A feeding reel 1 feeds a TAB tape (strip-shaped body) 3. A winding reel 11 winds the strip-shaped body 3. An automatic inspecting part 31 sends an image which is obtained with a line sensor camera 33 into a signal processing device 35. The pattern of the image is matched with the pattern of a reference image which is stored beforehand. Thus the presence or absence of a defect is judged. The position of the defect in the frame is stored in a memory device through the signal processing device 35. When the information that the defect is detected is received with a puncher 61 as a marking means from the signal processing device 35, the puncher 61 is operated after the frame having the defect is sent to the position of the puncher 61. Then, a hole is punched in the strip-shaped body 3. The hole which is formed at this time has the diameter which can be readily recognized with the human eyes.

Filed: 1984-08-20
Abstract: PURPOSE:To reduce the print time of a hard copy device while reducing the transfer time by providing a data transfer control circuit, checking a pattern data so as not to transfer a part without any data display. CONSTITUTION:The data read from a pattern display memory 2 is transferred to a data comparison circuit 21 via a longitudinal/lateral conversion circuit 3, and when the result of detection shows a print data, the control is transferred to a data transfer control circuit 23. When the result indicates a space data, the control is transferred to a space data count circuit 22, where the data is counted and stored. When the data for one line's share is all space data, the control is transited to the circuit 23. When the data is transferred to a hard copy device 5 and only when a print data appears as to the data for one line's share, only the space data appearing in precedence over the print data and the succeeding print data are transmitted to the device 5. Thus, since the space data not requiring print is not transmitted to the device 5, the transfer time and print time are reduced.

IPC: C25C3/04
Filed: 1980-12-04
Abstract: PURPOSE: To improve electrolytic efficiency, and to extend the life time of an electrolytic cell, by making molten Mg float on the surface of molten salt in a collecting chamber, and closing the upper part of said chamber as tight as possible, and by providing a means for heating the floating Mg in said chamber.  
     CONSTITUTION: A cylindrical scooping device 10, made of firebricks or heat resistant steel and installed on the upper part of a collecting chamber 6, penetrates through a cover 9 until its lower end is immersed near the surface of the solidified layer of the floating Mg 8, or in the molten layer 8". A sealing cover is attached to the upper end of the scooping device 10. A charging device 11 for MgCl 2  is installed similarly so that its lower end reaches the molten salt 7, and a cover is attached to the upper end. A heater 12 for Mg 8 is provided in order to heat the floating Mg 8. The Mg 8 produced in the electrolytic chamber 1 is collected to the upper part of the collecting chamber 6 by a trough 4. The electrolysis is performed at about 660W670°C temp., however Mg must be scooped up at ≥680°C temp., so that equipment of the heater 12 allows to scoop Mg out by heating at a low temp. for a short time. Because the cover 9 is always put on, the generation of sludge is also prevented.

Title: Printing press
Inventor: KUROSAWA SEIICHI
IPC: B41F33/06
Filed: 1987-07-09
Abstract: PURPOSE:To enable both thick printing paper and thin printing paper to be printed on a single press, by switching the timing for starting transmission of a rotating force from a rotating force transmitting means to a rotating means, to either a predetermined timing or a timing delayed behind the predetermined timing by a predetermined period of time. CONSTITUTION:With printing started, the leading end of a printing paper 12 comes into contact with a front guide 23, and is thereby once stopped. Thereafter, when the front guide 23 is tilted down forward or lifted upward, a cam 42 rotated in the direction of an arrow together with a transfer cylinder 28 comes into a roller 46 with a predetermined timing. By this, a lever 43 is turned counterclockwise, and a feeding roller 21 started rotating in the direction of an arrow by the action of the meshing of a rack 52 and a pinion 55, whereby the paper 12 is normally fed. A variation in the position of the roller 46 causes a variation in the timing for the contact of the cam 42 with the roller 46, whereby the contact can be delayed by a predetermined period of time.

Abstract: PURPOSE:To obtain an exclusive OR signal and an AND signal with simple constitution by mixing input optical signals and distributing then at a specific intensity ratio, and using two optical bistable semiconductor lasers. CONSTITUTION:An optical mixing and distributing means mixes and distributes the 1st and 2nd input optical signals at the specific intensity ratio and they are inputted to a 1st optical bistable semiconductor laser with 1st input light intensity and a 2nd optical bistable semiconductor laser 38 with 2nd input light intensity.

Therefore, the optical output signal of the 1st optical bistable semiconductor laser 34 is used as a sum output and the optical output signal of the 2nd optical bistable semiconductor laser 34 is used as a carry output to enable this optical logic circuit to function as a half-adder. Consequently, the exclusive OR signal and AND signal are obtained with the simple constitution without using any optical demultiplexer.
