Title: Production of optical disk with guide groove
Inventor: OOTA MINEMASA
IPC: G11B7/26
Filed: 1986-08-27
Abstract: PURPOSE:To eliminate the need for a large-sized and costly device by coating a soln. of a resin hardly soluble in an org. solvent on a 1st photoresist layer and curing the same by heating to form an intermediate resin layer. CONSTITUTION:The intermediate resin layer 4' is provided as a thin film for partition to prevent the attack of the 1st photoresist layer 2 by the org. solvent of the 2nd photoresist layer 3 at the time of coating the 2nd photoresist layer 3 on the 1st photoresist layer 2. PVA is used as the resin layer having the substantial light transparency to prevent the shielding of laser light in order to inscribe guide groove parts and preaddress pit parts; for example, polymers such as polyacrylamide and methyl cellulose are also usable as the intermediate resin layer 4'. since the polymer is soluble in water, the thin film is easily formable by spin coating of such resin soln.

Title: Electrophotographic printer
Inventor: MIYAZAKI TORU
IPC: G03G21/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the deterioration of printed picture due to abnormal accumulation of toner in a cleaning part by providing a print controlling part which monitors the data for writing electrostatic latent image and determines the execution timing of toner discharging processing of the cleaning part when the data amount exceeds a threshold. SOLUTION: The print controlling part 20 receives the output of a data amount counting part 50 at every exposure operation, stores the output in CNT 46 after subjecting the same to cumulative addition, compares the threshold in a memory 42 with the value corresponding to the data amount of the effective data which are stored in CNT 46, and performs the monitoring. In such a manner, the data for writing the electrostatic latent image to a photoreceptor drum is monitored, counts the data amount which makes toner stick to the photoreceptor drum and determines the execution timing of toner discharging processing of the cleaning part 6 when the data amount exceeds the threshold. Thereby, the execution timing of cleaning processing is optimized and the deterioration of printed picture due to abnormal accumulation of the toner can be prevented.

Title: Plating treatment of spectacle hinge
Inventor: ISHIKAWA SHINZOU
IPC: C25D7/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To lock external thread shafts and to ensure smooth rotating operation by subjecting spectacle hinges to a composite plating treatment. SOLUTION: A lubricative and wear resistant composite plating film is formed by an easy plating treatment technique in a turning part 3. Namely, a sliding contact surface 11 is the intercontact surface of a stationary lower sliding surface and a turning upper sliding surface. The contained compd. particles 13 dispersed in the film base material 12 of the turning part 3 partly forms a rigid eutectic film 14 on the surface. In the case of, for example, a fluorine compd., the contained compd. particles are softened or dissolved by heating, etc., and are thereby codeposited on the surface, by which the lubricity is maintained as the eutectic film 14 and hardness is improved. The film base material 15 applied at a screw fixing part forms a sliding contact surface 11 by a soft sliding fit surface 17 by a small amt. of the contained compd. particles.  Further, blisters 20 by an edge effect are generated by a high current density in the parts at the front ends of the screw threads 19 of internal screw threads existing on the lower plate 5 of the screw fixing part. These blisters press the valleys of the external screw shaft, by which the effect of locking is obtd.

The part 6 shown by the pointer is retrieved by the part 4 based on the command key given from the mechanism 2. Then the retrieved command name, the command additional information, etc., are given to a processing mechanism 7. Thus the mechanism 7 carries out its processing. Then a command having a tree structure is controlled simply and at a high speed.

Title: Noise reduction circuit
Inventor: OHARAGI YOSHITAKA
IPC: H03F1/26
Filed: 1992-07-30
Abstract: PURPOSE:To reduce a common-mode noise component in a differential amplifier. CONSTITUTION:When a noise is produced in a constant current circuit 12 and a collector current I1 of a transistor(TR) Q1 of the circuit 12 is increased by DELTAI, a collector current I2 of a TR Q2 in the current mirror relation with the TR Q1 is to increase by the DELTAI. Thus, emitter currents I3, I4 of TRs Q3, Q4 of a differential amplifier 11 increase, and output voltages Vo, Vo' are decreased due to the increase in the voltage drop across loads 15, 16. The output voltages Vo, Vo' are added in terms of averaging by an averaging adder circuit 21 and the result is used to control the current I1 as a control voltage in a form of (Vo+Vo')/2. Thus, emitter currents I5, I6 of TRs Q5, Q6 are decreased, and as a result the increase in the current I1 is suppressed.

Filed: 1986-08-29
Abstract: PURPOSE:To speed up clearing and counting operation and to improve the accuracy of measurement by passing a time measurement start and end signal through a clear pulse generating circuit, and varying its pulse width to narrow constant width and using it as a counter clearing signal. CONSTITUTION:The time measurement start signal and a differential clock signal which has narrower pulse width are inputted to a D type FF 11 and a delay output generated at the rise of the differential clock signal is inputted to a D type FF 12 to generate a further delayed output. The output of the FF 11 and the inversion output of the FF 12 are inputted to a NAND gate 13 to generate a signal for clearing a counter circuit 1 and the signal is sent to the clear terminal of a counter 22 to enter a clear state throughout an 'L'- level period and also holds the Q output of an FF 20 at 'H' level at a rising point through an inverter 25, so that a time clock signal is enabled to be sent to the clock terminal of the counter 22. Therefore, when there is the rising point of the time clock signal in the 'L'-level period of the clear signal, the time clock is counted by the counter 22 and the clear period is shortened.

Patent JP-H0252519-A (JP)
Title: Switching circuit
Inventor: MATSUMURA YUTAKA
IPC: H03K17/16
Filed: 1988-08-16
Abstract: PURPOSE:To attain stable switching by using a diode and a resistor so as to give a constant current to a transistor(TR), making the bias point potential constant and excluding the AC impedance of the TR through the resistor. CONSTITUTION:Since the voltage drop across diodes 8, 9 is always constant, even if the power voltage is fluctuated, a constant current flows to a TR 3. The current flows through a resistor 4 to cause a constant voltage at a bias point A. Then an AC input signal from a signal line 10 is superimposed on the bias voltage and the result is fed to a base of a TR 1. On the other hand, a resistor 21 is inserted between the resistor 4 and the collector of the TR 3, then the parasitic impedance of the TR 3 is eliminated in terms of AC. Thus, the Ac input signal from the signal line 10 is not subject to the effect of the parasitic impedance of the TR and stable switching is obtained.

Title: Absorptiometer
Inventor: YASUNAKA TOSHIO
IPC: G01N21/27
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To enhance the light collection efficiency by forming an acutely tapered light guide path opening in front of an LED and the light receiving face of a receiving optics. SOLUTION: A sample flowing through a transparent tube 9 is irradiated with a light emitted from a light source, i.e., an LED 32, and the quantity of transmitted light is detected by a photodiode 34 (receiving optics) in order to measure the absorbance of the sample continuously. Axial length of a light guide path 35b is set equal to two times or more of the difference of radius so that the level difference between a holding part 35a and the forward end part 35c of the light conduction path is varied slowly. Consequently, the light guide path 35b opening in front of the LED 32 is tapered acutely. Similarly, the light guide path 35b opening in front of the light receiving face of the photodiode 34 is tapered acutely.  Since the irradiating light can be collected more and converged finely, an absorptiometer having high light collecting efficiency can be realized through a simple structure.
