Title: Image processing unit, its method and serving medium
Inventor: MIHARA KANJI
IPC: H04N19/159
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To improve subjective image quality by people by selecting a quantization matrix different from a quantization matrix that used at decoding as a quantization matrix used for quantization corresponding to a quantization index calculated by a variable length code resulting from converting data quantizing image signals. SOLUTION: A VLC device 15 converts data resulting from quantizing an image signal by a quantization device 14 into a variable length code, and a rate controller 17 calculates a quantization index from this variable length code. A matrix selector 42 selects a quantization matrix different from a quantization matrix used at decoding for a quantization matrix used by the quantization device 14 corresponding to this quantization index. A matrix replacement device 41 replaces the quantization matrix used by a quantization device 41 with a quantization matrix whose quantization step of high frequency components of the quantization matrix used by the quantization device 14 is changed into a smaller value. Thus distortion of the image at quantization and inverse-quantization is suppressed.

Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To satisfactorily execute soldering even under the condition of non-flux by plating an aluminum base composite material with an Ni layer, thereafter executing heating and reducing away an oxidized film in the Ni plating layer. SOLUTION: An aluminum base composite material is plated with an Ni layer and is thereafter heated at about 200 to 500 deg.C in a reducing atmosphere to reduce away an oxidized film in the Ni plating layer. Alternatively, the oxidized film in the Ni plating layer is removed by using an acidic soln. Further alternatively, the oxidized film in the Ni plating layer is removed by grinding. The peak value of the concn. of oxygen in the Ni plating layer formed on the surface of the aluminum base composite material is controlled to <=10 at.%. In order to measure the oxygen concn. in the Ni plating layer, Auger electron spectroscopy suitable for the quantitative analysis of the surface compsn. is adopted. It is preferable that soldering is executed directly after the removal of the oxidized film in the Ni plating layer.  In the case there is a long time before soldering, preferably, it is stored in a nonoxidizing atmosphere.

Title: Developing roller
Inventor: MIMURA KAZUYOSHI
IPC: F16C13/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To obtain a roller which is soft and nonadhesive to a photoreceptor and has little dependence on environments such as humidity and temp. and excellent toner release property by incorporating two or more kinds of resin components into a surface layer to form a sea-island structure having a matrix as a soft component and a domain as a rigid component. SOLUTION: The matrix resin in the sea-island structure is required to be more flexible than the domain resin. By incorporating the domain resin into the matrix resin, the adhesion property of the matrix resin is suppressed and the surface layer becomes nonadhesive to a photoreceptor. Therefore, it is preferable that the fracture elongation of the single matrix resin is controlled to >=200%, while the yielding elongation of the single domain resin is controlled to <=100%. The sea-island structure is preferably formed to have 1 to 10μm domain size. As for the domain resin, an epoxy resin and urea resin can be used. As for the matrix resin, an urethane resin and silicone rubber can be used.

Title: Gain control circuit
Inventor: OSHITA KAZUAKI
IPC: H03G3/12
Filed: 1986-11-08
Abstract: PURPOSE:To obtain a decibel-linear characteristic with simple circuit constitution by forming a part of an ideal transfer function showing linear change by a linear circuit system approximately so as to omit an input resistor of the amplifier. CONSTITUTION:A transfer function between input and output terminals of an amplifier is selected to be (RB/(RA+RB))(1+Rf/Rs), where RB is a resistor of a variable resistance circuit network obtained through the changeover by a digital code signal. Moreover, each value in the transfer function is selected so that the transfer function change region between the input and output obtained by varying the resistor RB is in the linear region where a difference between the linear characteristic in the ideal transfer dunction and the decibel- linear characteristic by logarithmic representation is small. In varying a value Rf/Rs by using a high order digital code signal, the transfer function change region is expanded. Thus, the decibel-linear characteristic is obtained while the simple circuit constitution is applied without the need of a resistor at the input side of the amplifier.

Title: Abnormality detecting device for crank angle sensor for engine
Inventor: TANAKA YASUSHI
IPC: G01B21/22
Filed: 1985-11-26
Abstract: PURPOSE:To detect a place where an abnormality has occurred easily and rapidly by judging that an abnormality has occurred in either of an REF signal system or a POS signal system, from the number of pulses of a POS signal which is generated in one period of an REF signal. CONSTITUTION:When an abnormality has occurred in an REF signal system causing an REF signal 100 and a Q signal 104 which should rise in a defined time t1 to fail, the pulse count of a POS 102 by a binary counter 16 is continued as it is, allowing a pulse count value to exceed the predetermined pulse generating number. Thereby, the abnormality detecting signal 106 of an AND circuit 30 in a counted number judging circuit 20 becomes '1'. On the other hand, if an abnormality occurs in a POS signal system in which a pulse in the POS signal 102 temporarily fails over a defined time t2-t3, the pulse count value by the binary counter 16 is forcedly made zero, outputting an abnormality detecting signal 110 of '1' from a binary counter 38 to a terminal 40.

IPC: G03D15/00
Filed: 1989-10-12
Abstract: PURPOSE:To suppress the increase of an initial cost and to allow simple fare calculation by recording the fare table for developing and printing on a bag part. CONSTITUTION:After negative pieces 25 for one order are inserted, a printing controller 23 operates a printing head 22 and prints the fare table on the bag part 10D next to the bag part 10D inserted with the final negative piece 25. The printing of this fare table is executed in accordance with the printing data form a fare computing section 35. The fare computing section 35 counts the number of prints from the frame information stored on an LSI card 14 and calculates the print fare by multiplying the count value by the unit price of the print. The computing section also determines the sub-total which is the sum of the unit cost of development inputted by the operation of a keyboard 36 and the print fare. The increase of the initial cost is suppressed in this way and the fare calculation is facilitated.

Title: Lighting apparatus
Inventor: HASHIBATA MICHIHARU
IPC: F21V29/00
Filed: 1987-10-21
Abstract: PURPOSE: To prevent conductive foil from being disconnected by providing a thermal insulating plate having radiation fins outside a reflector and a cylindrical shielding member around a sealing portion opposite to the sealing portion, and further thermally connecting an end portion of the shielding member to a thermal insulating plate. CONSTITUTION: A lamp 3 is lit on and, reflecting light from a reflector 1 by the lamp 3 tends to advance to a sealing portion 4. However, the advance of the reflecting light is shielded off by a shielding member 7. Therefore, the increase in temperature of the sealing portion 4 is suppressed. On the other hand, heat absorbed to the shielding member 7 is transmitted to a thermal insulating plate 5 because the end portion of the shielding member 7 is thermally connected to the thermal insulating plate 5, thereby radiating heat via a radiator fin 6. Thus, the overheating of the sealing portion of the lamp 3 is suppressed, thereby improving the service life of the lamp.
