Title: Semiconductor device
Inventor: TAKEI AKIRA
IPC: H01L27/148
Filed: 1983-09-17
Abstract: PURPOSE:To enable the incorporation of a driver even in a large-scale CCD image sensor by a method wherein the driver which outputs clock voltage is provided on the same semiconductor substrate. CONSTITUTION:When a photo image is projected by application of a charge accumulation voltage on the electrode of a photoelectric conversion part 12, charges corresponding to the picture element of the photo image generate in each subdivision of the photoelectric conversion part. When a transfer gate 18 is opened by application of a voltage, and a transfer voltage is then impressed on CCD parts 14 and 16, the charges in each subdivision of the part 12 flow in alternately to the side of CCD14 or CCD16 through the gate 18 as shown by arrows, and next transferred to the side of an output gate 36. The transfer voltage consists of a constant DC potential E in one phase, and a rectangular wave clock phi1 or phi2 in the other phase, both of which can transfer charges in the same manner as the double-phase drive of the rectangular wave clock. Besides, a driver is unnecessary because of the DC potential in one side; therefore the number of drivers can be reduced to half, and a driver-loaded 2K picture element CCD image sensor can be realized.

Title: Photosensitive body for positive electrostatic charge
Inventor: FUJIMAKI YOSHIHIDE
IPC: G03G5/14
Filed: 1984-08-17
Abstract: PURPOSE:To form an always satisfactorily visible image by providing a blocking layer contg. a carrier transfer material exhibiting the same ionization potential as said potential of the carrier transfer material or smaller than said potential under the single photosensitive layer consisting of a granular carrier generating material having the photosensitive higher in the negative electrostatic charge stage than in the positive charge stage, a carrier transfer material and binder material. CONSTITUTION:The implantation of electrons from an underlying electrode arises and substantial acceptive potential is not obtainable with the photosensitive layer 4 alone. However, the implantation of the electrons from the substrate 1 is blocked by the blocking layer 5 and the holes to be implanted from the layer 4 can be effectively transferred to the conductive substrate side. The material having transferrability of positive holes is incorporated into the layer 5 for the above-mentioned purpose and the implantation of the positive holes from the layer 4 is made easy. Such implantation is effectively attained by incorporating the carrier transfer material having the same ionization potential as the ionization potential of the carrier transfer material in the layer 4 or the smaller than said potential into the blocking layer.

Title: Command input filter
Inventor: IKEMOTO MASUO
IPC: H02P29/00
Filed: 1991-07-12
Abstract: PURPOSE:To protect an output signal against the influence of noise by integrating the difference between digitized input and output signals and switching the output signal to the input signal at that time every time when thus integrated difference exceeds an appropriately selected set value. CONSTITUTION:An analog command signal fed to a motor controller is subjected to digital conversion through an A/D converter l and then fed to a switching holder 2 and a subtractor 3. The subtractor 3 determines the difference between a digitized input signal I and an output signal (O) at that time and the difference is integrated through an integrator 4. An absolute value generator 5 generates the absolute value ¦S¦ of the output from the integrator 4 and a comparator 6 compares the absolute value ¦S¦ with a preset value C. When the ¦S¦ reaches C, switching signals are fed to the switching holder 2 and the integrator 4. Upon receiving the switching signal, the switching holder 2 switches the output signal (O) to the input signal I at that time thus holding the output signal (O). According to the invention, adverse effect of noise being carried on an input command can be eliminated.

Abstract: PURPOSE:To attain ease of listening of received sound by using a switch so as to decrease transmitted sound volume and to increase received sound volume when the surrounding noise is large during talking and the received sound volume is small. CONSTITUTION:When a switch 2 is turned off, the transmission input from a handset 1 is amplified with a gain of (1+R1/R2) times by a transmission amplifier A1 while a switching element FET1 is turned off and the gain of the transmission signal is increased. Since the FET2 is turned off, the gain of the reception signal at the reception amplifier A2 is unity. When the switch 2 is turned on, the FETs 1, 2 are turned respectively on through R6, R7. Since the FET1 is turned on, no transmission signal is transmitted to a hybrid transformer 4. When the FET2 is turned on, the reception signal has a gain of (1+R4/R3) times by using the A2 than the case with the switch 2 turned off, to increase the gain of the reception signal.

IPC: B65H63/08
Filed: 1983-09-21
Abstract: PURPOSE:To enable the accurate detection of the residual quantity of electric wire without the influence of variablity of a resistance value by a method wherein an electric resistance is measured at each time of completion of winding and the resistance value of the electric wire of the length necessary for one winding is calculated based on the average of the measured resistance values and the calculated value is compred with each measured value. CONSTITUTION:The electric resistance r0 of an electric wire 1 of the section held by a chuck 8 and a chuck 15 is measured and is stored in a microcomputer. Next, the resistance r1 between a new front end and a terminal is measured and R1=r0-r1 is obtained. Then, the electric resistance Ri or (i) times is measured at completion of winding operation of each time and is stored in a computer which calculates the average of variation of resistance value Ri=ri-1-ri. Based on this average value, the resistance value of an electric wire of the length necessary for one winding is calculated and this calculated value is compared with the measured value ri or each time to determine whether the residual quantity of a wire at measurement of (i) times has the length necessary for one winding or not. Consequently, the accurate detection of residual quantity of an electric wire can be done without the influence of the variability of resistance value per length of wire of each manufacturing lot.

Title: Voltage drop detecting circuit
Inventor: MATSUDA YUKIKAZU
IPC: H02H3/24
Filed: 1980-12-10
Abstract: PURPOSE:To detect a drop in power voltage by variation in the output of a logical element whose output voltage changes from a high to a low level once an input voltage drops to nearly a half as high as the power voltage of a storage battery, etc. CONSTITUTION:To the input terminal of an NOT circuit 12 as a logical element, a voltage V1 obtained by dividing a power voltage Vc by a constant voltage element 13 and a resistance R11 is applied. This voltage V1 is expressed by V1= Vc- VF, where VF is a value obtained by the element 13. On the other hand, as  the power voltage Vc drops, the input voltage V1 also drops and once V1<=Vc/2  at a point t1 in time, the output V0 of the NOT circuit 12 is inverted to output a voltage nearly equal to the Vc at the point in time. Then, a transistor (TR)15  turns on and a light emitting diode 14 comes on to give a warning of the drop  in power voltage. In addition, when V1>Vc/2, the output V0 of the NOT circuit  is at 0V and the TR15 turns off, so that the light emitting diode 14 never  comes on.

Title: Digital color copying machine
Inventor: TSUBOI TOSHIO
IPC: B41J2/525
Filed: 1988-07-12
Abstract: PURPOSE:To develop no error in selecting color adjustment by providing a density setting means automatically setting a printing density level at a reference value when printing is carried out in a mosaic monitor mode. CONSTITUTION:In the initialized mosaic monitor mode, the density setting means 80 automatically sets a density level at the reference value. Consequently, plural images are printed at the reference density level in the mosaic monitor mode, in which the density setting means 80 is not needed. Therefore, the density level set by the density setting means 80 is previously accorded with a color adjustment coefficient, and the density setting means 80 itself adjusts a color adjustment coefficient. Since density is set at the reference value in the mosaic monitor mode all the time, color adjustment is not mistakenly selected.
