Inventor: TANAKA AKIKO
IPC: B29D29/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain an endless belt made of polyimide having a multilayered structure good in close adhesion between respective layers and free from partial resistance irregularity. SOLUTION: A soln. of a polyamide acid in a solvent is injected in a rotary cylindrical mold to form a first layer film and the solvent is evaporated by the heating of the cylindrical mold to fix the polyamide acid and this cylindrical mold is heated to imidate the polyamide acid within an imidation ratio range of 50-90%. A second polyamide acid soln. wherein carbon is dispersed in the polyamide acid solvent soln. is injected into the cylindrical mold under rotation to form a second layer film and the solvent in the second layer film is evaporated by heating the cylindrical mold to fix this polyamide acid. The polyimide precursor in the first layer and the polyimide precursor in the second layer are perfectly imidated by heating the cylindrical mold.  The endless belt obtained by the demolding from the cylindrical mold is useful as the intermediate transfer material of a full color image forming apparatus.

Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To improve voice quality at a low bit rate of about 4 kb by specifying a driving source vector candidate of an object channel among driving sound source vectors with indexes to other channels. SOLUTION: The indexes of a pulse 1 and a pulse 2 outputted from a pulse-1 index generator 101 and a pulse-2 index generator 102 are inputted to a 1st index/pulse position converter 104 and a 1st index/pulse position converter 104 determines the pulse position of the pulse 1 by using those two indexes.

Title: Method and device for detecting magnetic foreign matter
Inventor: UCHINO IKUO
IPC: G01N27/72
Filed: 1989-03-10
Abstract: PURPOSE:To accurately detect the presence or the absence and the quantity of magnetic foreign matters in a fluid to be detected even in the case of fine particles of magnetic foreign matters by approximating a permanent magnet to the fluid to be detected with a particle holding plate between them to attract and gather magnetic foreign matters in this fluid to the particle holding plate. CONSTITUTION:Since the magnetic flux passing a magnetic detecting element 3 of a detector 1 is changed by the quantity of magnetic foreign matters 6 gathered by a particle holding plate 4 to which the element 3 is approximated, the density of the magnetic flux passing the element 3 is detected to detect the quantity of foreign matters 6 gathered by the holding plate 4. Consequently, this detected value is checked to estimate the presence or the absence and the quantity of foreign matters 6 in a fluid 5 to be detected. Since the detector 1 is attached to the center of the magnetic pole surface of a permanent magnet 2, the magnetic flux of the magnet 2 passes in the direction approximately orthogonal to the element 3, and the change of the magnetic flux is detected with a high sensitivity. Temperature compensation is performed by a temperature compensating element attached to the magnet 2 together with the element 3 and a temperature compensating circuit connected to this temperature compensating element.

The differential voltage, after being converted to an electrical signal at a voltage current conversion circuit 7, is converted further to the voltage signal by a current voltage conversion circuit 8. And the output voltage of the circuit 8 is impressed on the gate of a FET11 at the output stage 9, and the output voltage of the amplifying stage 3 is impressed as it is on the gate of a FET12. By constituting a device in such a way, it is possible to adjust a level shift quantity automatically so as to always keep a constant bias current by the output stage 9 even when the fluctuation of the power source voltage or the device characteristic is generated.

IPC: H01L21/28
Filed: 1992-02-07
Abstract: PURPOSE:To prevent over-etching by removing a polymerized film which is formed on the inner surface of a groove part in a process of forming a window in an insulating film by dry-etching. CONSTITUTION:A process of eliminating a polymerized film 8a formed on the inner surface of a groove 6a which has already been formed in an insulating film 2 is inserted into a process of forming a window 5 in the insulating film 2 by a dry-etching method.

Title: Code error correcting system
Inventor: OISO MITSUO
IPC: H03M13/00
Filed: 1985-03-20
Abstract: PURPOSE:To attain the perfect detection of an error correction unable state and to improve the reliability of a code error correcting system, by performing collation between error locations obtained in the form of the (t) character correction and the (r) character correction larger than the (t) and detecting the discordance of this collation. CONSTITUTION:A memory 10 stores temporarily the received codes, and a syndrome producing circuit 11 produces a syndrome from the received codes according to a check matrix. This syndrome is transmitted to a circuit 12 to obtain the error location as the (r) character correction as well as a circuit 13 to obtain the error location as the (t) character correction respectively. Then each error location is obtained by the Euclid mutual deletion method, etc. The information on both relocations are collated with each other through a collation circuit 14. Then the received code is corrected by a correction circuit 16 only when the coincidence is obtained from said collation. Thus it is possible to detect perfectly an error correction unable state and to improve the reliability of a code error correcting system.

Title: Manufacture of insulated coil
Inventor: HAKAMATA TAKESHI
IPC: H01B13/16
Filed: 1978-05-15
Abstract: PURPOSE: To suppress the foaming in an isocyanate-containing impregnated resin and prevent the deterioration of insulating characteristics, by thoroughly setting a silicon resin in an insulator layer and by imprengating and setting the impregnated resin after a catalyst for setting the silicon resin has lost its effect.  
     CONSTITUTION: The setting catalyst such as a lower amine is contained in the insulator layer containing the silicon resin. After the silicon resin is thorougly set and the effect of the setting catalyst is lost, an imidazole derivative or the like is impregnated as a setting catalyst for the impregnated resin into the insulator layer. The impregnated resin containing an isocyanate as a constituent is then impregnated into the insulator layer and set. Thus, the production of water due to the setting reaction of the silicon resin is prevented when the impregnated resin is set. As a result, the foaming in the insulator layer is suppressed and the insulating characteristics do not deteriorate.

Title: Band pass filter circuit
Inventor: KATOU TADAYOSHI
IPC: H04L27/227
Filed: 1983-03-31
Abstract: PURPOSE:To prevent the deterioration is S/N of an output signal without changing the output phase at fluctuation of an input frequency by extracting a required band from an input signal, frequency-dividing it, phase-shifting one of its outputs on one hand, multiplying the other on the other hand and mixing both the outputs. CONSTITUTION:The required band is extracted from the input signal through a BPF12 and is frequency-divided by a frequency-divider 13. An output of the frequency-divider 13 is shifted in terms of phase by a phase frequency characteristic circuit 14, and on the other hand a frequency component multiplying an output frequency of the frequency divider 13 is generated by a multiplication means 15. Further, a mixer 16 mixes the output of the circuit 14 and the means 15 and outputs a difference frequency component. As a result, the output phase is made unchanged even if the input frequency is fluctuated and the deterioration in the S/N of an output signal is prevented.
