Title: Paper feeding controller
Inventor: TADAUCHI YUKIO
IPC: B65H7/18
Filed: 1984-06-28
Abstract: PURPOSE:To improve the efficiency of copying work as well as to make a copying miss preventable from occurring, by feeding paper automatically out of one side paper feed cassette even there is a feed miss of paper out of the other side paper feed cassette at a time when plural cassettes are selected. CONSTITUTION:When plural cassettes are selected by a mode select switch, it advances on paperfeeding motion from both upper and lower cassettes, but is upper cassette paper feeding is the case, paper feeding is started with an upper feed roller clutch turned on, and if lower cassette paper feeding is the case, the paper feeding is started with a lower clutch turned on. Next, simultaneously with these feed roller clutches getting driven, a timer is set in motion, and when a feed miss drtecting switch 11 fails to work even after the elapse of the specified period of time, a feed miss is to be detected. And, an enable flag corresponding to the cassette at the side where the feed miss occurs is set down to 1 and paper feeding from the next time is forbidden. If the mode select switch comes to a plural-cassette select mode, the paper feeding takes place from the cassette having paper of the same size.

Title: Logarithmic compressing circuit
Inventor: MIYAKE TOSHIHIDE
IPC: H03G7/06
Filed: 1981-08-26
Abstract: PURPOSE:To perform phase compensation and to stabilize operation by connecting a couple of resistances in series between bases of transistors (TR) forming a current mirror circuit, and also connecting a phase compensating capacitor between the base and collector of the TR on the amplification stage. CONSTITUTION:When the output current of a photodiode PD is to be compressed logarithmically by a TRTro, a couple of resistances Ra and Rb are connected between bases of NPN TRs Qc and Qb forming a current mirror circuit in an operational amplifying circuit OP2 connected to the photodiode PD, and a capacitor C1 with small capacity is connected in series between the base and collector  of the amplification stage TRQb. Thus, the resistance about ten times as great as the impedance of the TRQc is inserted betweeh the bases of the TRQc and TRQb, so the time constant of feedback is increased and the required capacity of the capacitance C is made less than that of a conventional circuit of the same  kind accordingly. Consequently, the IC-implementation is facilitated.

Title: Restarting device of digital control type brushless motor
Inventor: TORII MICHIHIRO
IPC: G11B15/093
Filed: 1979-10-18
Abstract: PURPOSE:To automatically restart the brushless motor which is in standstill because of excessive loads by a method wherein the frequency of pulse signals is gradually increased from a self start frequency or less to a frequency during a normal operation time by means of a rotation stop detection signal. CONSTITUTION:When starting signals are inputted, trigger signals are generated in a start/restart control circuit 5 which trigger a frequency variable oscillating circuit 4 to rotate a digital control type brushless motor 1. For example, in case of a need switch, when a sensor 6 is rotating, ON/OFF operations continue, as a result, if ON/OFF operations stop, it means that the rotation of the motor 1 stops. And further, the motor 1 is automatically restarted by a method wherein a rotation stop signal is sent from a detection circuit 7 to the start/restart control circuit 5, and the frequency variable oscillating circuit 4 is retriggered and then, the oscillating pulse CLK is made to return to a frequency equal to the self start frequency or less and thereafter, it is gradually being raised to the frequency during the normal operation time.

Title: Door device for electronic appliance
Inventor: TOYOSHIMA SHIGERU
IPC: G11B33/02
Filed: 1994-06-16
Abstract: PURPOSE:To attain cost reduction with a simple constitution as to a door device of the electronic appliance for recording/reproducing the recording media such as a magnetic tape, etc. CONSTITUTION:By means of pressing a 1st guide piece 82a with the magnetic tape 90, a door member 82 is slid to the retreating position while pressing an elastic member 83 to enable the magnetic tape 90 to be inserted. When the magnetic tape 90 sliding on the 1st guide piece 82a is passed through the top part 82g of the door member 82, the door member 82 is pushed up by the repulsive force of the elastic member 83 which has been compressed. As a result, the door member 82 is slid and returned to the original projecting position. Thus, the opening/closing operation of the door member at the time of inserting the magnetic tape 90 is finished. When the magnetic tape 90 is ejected, the door member 82 is opened/closed by the same operation as at the time of insertion except when the magnetic tape 90 is slid on a 2nd guide piece 82b. Consequently, the door member 82 is completely closed up for dustproofing without using the electronic parts such as an electromagnetic plunger, etc., and also at the time of loading the magnetic tape 90.

Title: Correlation value operating method
Inventor: TAKEMOTO MITSUO
IPC: H04L25/03
Filed: 1984-07-02
Abstract: PURPOSE:To prevent converging errors from being increased even when a value to a coefficient replacing gain in the MS algorithm is decreased by adding a constant in advance to an accumulator at the initial stage in a correlation operation of a reception automatic equalizer. CONSTITUTION:A constant K is added and inputted to the accumulator 11.

Title: Fabric for supporting filter membrane
Inventor: OIKAWA KATSUHIKO
IPC: D03D25/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To ensure supporting of a filter membrane and at the same time, improve the resistance to press damage and inhibit the deterioration of a filtration efficiency due to a change in the space between pleats by providing a fabric for supporting the filter membrane consisting of fluororesin warps/wefts of a varying thickness and specifying arithmetical mean deviations of profile on both faces and their relation. SOLUTION: A material fluorine fiber uses a fluororesin having a melt spinning performance and is formed by melt-extruding the resin from a die head of a specified shape. Further, the fabric for supporting a filter membrane is woven using the fluorine fiber. In this case, at least two fibers having a different thickness from each other so that either of the warp or the weft is bent more significantly than is the other, are used. Thus the fabric has an irregular face on one side and a plain face on the other side. The arithmetical mean deviations of profile (Ra) on one side of the fabric is sent to be 0.5-40 μm and the arithmetical mean deviation of profile on the other side is set to be 1.5-15 times that of the one side.  Consequently, it is possible to positively support even a thin polymer filter membrane and at the same time, regulate the flow of a material to be filtered with high efficiency.
