Title: Intermediate tone reproducing system for facsimile unit
Inventor: YAMAMURA MASARU
IPC: H04N1/23
Filed: 1979-02-20
Abstract: PURPOSE: To reproduce the intermediate tone of facsimile signal with fidelity, by converting the reception video signal including the intermediate tone into the pulse train having the width corresponding to the level.  
     CONSTITUTION: The system consists of the detection circuit 1 and the oscillation circuit 2 oscillating triangle waves having higher frequency than the specified maximum video frequency. Further, the detection output 1' makes level change in response to white and black of original; low level L corresponds to white, high level H to black, and changed part of intermediate level to the intermediate tone. At the area where the oscillation output 2' is not exceeded negative from the detection output 1', the compared output 3' is VEE. When the part in excess of negative part is caused, the output 3' momentarily increases to V cc  to keep V cc  for the period in excess of it. The more the output 1' goes to the level H, the longer is the period in excess of negative side of the triangle waves 2' developed one after another and the longer is the pulse width of the output 3'. This output 3' indicates intermediate tone and it the pulse train having the width corresponding to the change in the intermediate level of the output 1'. If the output 2' does not exceed the output 1', the output 3' is fixed to V cc . By applying the output 3' like this to the recording electrode, the size of nozzle spattered particles of ink jet system changes correspondingly.

Title: Manufacture of iron core
Inventor: YAMADA KAZUO
IPC: H01F1/153
Filed: 1985-02-04
Abstract: PURPOSE:To sufficiently utilize the magnetic characteristics that an amorphous magnetic alloy inherently has and to obtain a high quality iron core, by disposing the iron core formed of a sheet of the amorphous magnetic alloy within a vacuum tank, and exciting the core at a high frequency so that the core is increased in temperature and annealed by the heat generated by the core itself. CONSTITUTION:In order to anneal a wound core 11 for eliminating strain, the inside of a vacuum tank 15 is evacuated to produce a vacuum or reduced pressure condition there. An exciting coil 14 is connected to a high frequency AC power supply 19 through a changeover switch 18 and is supplied with high frequency AC current with a voltage regulated by a voltage regulator 21. When the exciting coil 14 is supplied with AC current, a magnetic flux generated thereby causes eddy current to flow through an amorphous magnetic alloy sheet 12 in the wound core 11, and the power loss caused by the eddy current causes the amorphous magnetic alloy sheet 12 to generate heat. Thus, the temperature of the amorphous magnetic alloy sheet 12 is increased by the heat generated by itself. When the temperature of the sheet 12 is increased to a proper annealing temperature, the voltage of the AC current is regulated by the voltage regulator 21 so that the temperature is held for a certain period.

Title: Circuit for adjusting automatically output level of ccd
Inventor: OKAMOTO KAZUHIKO
IPC: H04N1/04
Filed: 1985-02-04
Abstract: PURPOSE:To obtain a signal at a constant level even if the intensity of the rays of light is changed by counting a count pulse during the prescribed period based on the output of a logic means at the time of automatic adjustment and switching an analog switch. CONSTITUTION:When the peak of a CCD output is lower than either of thresholds TH1 or TH2, the output of an NAND gate 20 comes to ''1'' level to set a counter 23 in a count-up mode. When the peak is higher than either of them, the output level of the NAND gate 20 is switched to ''0'' level, and the counter 23 is set in a counter-down mode. When the peak is set between the thresholds TH1 and TH2, a count pulse is hardly outputted to the counter 23. Thus the gain of an amplifier 11 can be adjusted so as to set the CCD output at a constant level.

Title: Fixing device with heat roller
Inventor: KOBAYASHI HOAKI
IPC: H05B6/14
Filed: 1981-02-12
Abstract: PURPOSE:To improve the fixing with the uniformity of temperature distribution in a fixing part and so forth, by adopting the induction heating system, where a roller itself is a direct heating unit, in a fixing device. CONSTITUTION:A laminated iron core 13 is passed through rollers 11 and 12 in the direction of their axes into a ring, and coils 18 and 19 to which AC power is supplied are wound around both end parts of the laminated core outside rollers. When power is supplied from an AC power supply 20 to the coil 18, the density of the generated magnetic flux in the roller part is decreased from the left toward the right. Therefore, the temperature distribution in the direction of roller axes in parts of rollers 11 and 12 is lowered from the left toward the right. Similarly, when power is supplied from the AC power source only to the coil 19, the temperature distribution in the direction of roller axes is raised from the left toward the right. Consequently, when power is supplied to coils 18 and 19 from the AC power supply 20 simultaneously, the temperature distribution in the direction of roller axes in a press-contact part 21 becomes uniform. Roller themselves become direct heating units. By this constitution, the fixing of the toner image is improved, and the device is small size.

Filed: 1994-01-20
Abstract: PURPOSE:To provide an apparatus for measuring vehicle speed, capable of usually making stable display and at the time of rapid speed change displaying vehicle speed promptly responding to the speed change. CONSTITUTION:A counter 2 counts input impulse signals SI to measure vehicle speed. A previous vehicle speed based on a previous count value is stored in and displayed on an output register 3. A display vehicle speed preceding the vehicle speed one time before the last is stored in an N-2 time display vehicle speed register 5. A display vehicle speed difference detecting device 6 calculates the absolute value of the difference between the two vehicle speeds, and a measuring time shortening multiplying- factor setting device 7 sets measuring time shortening multiplying-factor (M) and measuring time for this time T/M. A timing controller 1 makes the counter 2 count for the measuring time of T/M, and the display vehicle speed calculating device 4 multiplies the count value by the measuring time shortening multiplying factor (M) to calculate display vehicle speed value for this time. When the difference between the display vehicle speeds is large, the measuring time is shortened to display a vehicle speed value at short time intervals by moment, and when the difference is small, a stable vehicle speed value with high accuracy is obtained by use of sufficient measuring time.

Title: Protector for power inverter
Inventor: OJI MASATAKA
IPC: H02M1/00
Filed: 1992-02-06
Abstract: PURPOSE:To conduct a normal protective action for a switching element by having a temperature-difference initial value arithmetic means for additionally inputting a temperature difference between cooling fin and periphery immediately before the stop of operation as the initial value of an operated element junction temperature to an adding means. CONSTITUTION:A protector is additionally provided with a TF-A initial value operation part 18 and constituted in circuit so that the output of the operation part is additionally inputted to a T1 operation part 16, and inputs the value immediately before the stop of protective operation of a temperature difference TF-A stored in a nonvolatile storage element as the initial value T at the time of the restart of operation. Then, when the rated value Imr of output current at the time t4 is applied again, the starting point of operation of the temperature T1 slowly approaches a steady-state value T4 at the rated value because a temperature difference TJ-F becomes smaller after the starting point does not become an ambient temperature TA but rapidly increases in the manner corresponding to the rated value Imr. Further, when the output current of a converter is increased to a short-time rated current Ims at the time t5, the current gains in increasing speed and reaches an upper-limit set point I1max at the time t5. Therefore, it is possible to avoid the delay of protective action based on the interruption of operational action.
