Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To enable reduced printing by vertical scanning and horizontal scanning at need by performing horizontal scanning width detection on the assumption of cut paper. SOLUTION: When recording operation starts A1, a recording paper side detection sensor detects recording paper size A2 and conveys recording paper from a cassette. When constant-speed conveying operation starts A3, it is monitored whether or not a recording paper width passage sensor set at a position where the paper passes in a constant-speed conveyance state turns on A4 and when the sensor turns on, horizontal scanning width is detected while the recording paper calculation in the vertical scanning direction begins to be calculated. Therefore, the off operation of the recording paper width passage sensor is monitored A6 and when the sensor turns off, the recording paper length in the vertical scanning direction is calculated from the on time A7.  When the calculation results of the vertical scanning and horizontal scanning are the same as the size of the recording paper detected at A2 A8, a normal recording process is performed A9, but when not, that is alarmed and displayed A10.

Filed: 1980-06-23
Abstract: PURPOSE:To avoid the effect due to an input signal, by using a compensating OCD delay line having equal input and output characteristics as that of a main CCD delay line to control the bias charge of the main CCD delay line. CONSTITUTION:An input signal 14 superimposed with a bias voltage V1 is applied to an input gate G2 of a main CCD delay line 15 and a DC voltage equal to the bias voltage V1 is applied to an input gate G2C of a compensating CCD delay line 16. Input diodes ID and IDC for the main and compensating CCD delay lines are commonly connected and a sampling pulse 18 is applied with each pulse of a clock pulse commonly driving the main and compensating delay lines. Thus, an electric charge corresponding to the potential difference between input gates G1C and G2C is inputted to the compensating CCD delay line. When the output 20 is introduced to a control circuit 23 and the voltage for the input gates G1 and G1C is commonly controlled so that the value is constant at all times, the output 20 is controlled to a given value and the bias charge on the main CCD delay line 15 can be controlled to a given value.

Title: Control method and its apparatus for disk device
Inventor: ARIMA KAZUNORI
IPC: G11B21/08
Filed: 1986-04-15
Abstract: PURPOSE:To prevent the wear of a cylinder used for data read/write by moving a head to a prescribed cylinder position while a disk device is not used for a series of data access. CONSTITUTION:A timer 331 counts the absent state of seek after the head seek for a prescribed time. The head seek is caused by a signal SEEK or a signal INIT from a CPU 1, the timer 331 is reset at each occasion and started for the count again. Since a series of disk access is applied in general periodically, when the time of the timer 331 is over, the CPU 1 does not use the disk device for the purpose of the data access. Then a time-out signal TO of the timer 331 energizes a set switch circuit 332 and new seek is generated automatically depending on the set content of the set switch circuit 332. Thus, the head is in standby at a prescribed cylinder without any intervention of the CPU 1.

IPC: B30B15/02
Filed: 1995-04-11
Abstract: PURPOSE: To simply prevent defective blank holding caused by the vibration of a blank holder ring by making a part of plural fluid pressure cylinders ram as ramming cylinders at the time of blank holding when performing the drawing working of a press stock. CONSTITUTION: The pressure equalization cushion device 48 of a press working device 10 is composed of air cylinder 42, cushion pad 28, hydraulic cylinder, cushion pin 24, etc. A part of many hydraulic cylinders is rammed at the time of blank holding (at the time of drawing working) as barrel ramming cylinders 32b. Consequently, an approach position of a wrinkle presser ring 30 and a cushion pad 28 is specified. And also, uniform pressing cylinders 32a are held in a neutral state, and pressing loads are equally transmitted. In such a case, it is enough to install an only boss 40 on the wrinkle presser ring to make ramming cylinders 32b for ramming. Therefore, this mechanism can be applied to an existing press working device by a small modification.

Title: Forced charge/exhaust type gas combustion device
Inventor: KUROYANAGI HIROAKI
IPC: F23N5/24
Filed: 1981-06-03
Abstract: PURPOSE:To enable to perform a safe and stable operation, by a method wherein a device is caused to operate in a prompt reaction when a fan is switched from a slow operation mode to a fast operation mode, and it is caused to function in a delayed response when the fan is switched from a fast to a slow operation mode. CONSTITUTION:A timing circuit 13 is formed such than an output of a buffer amplifier 7 works directly on a differential amplifier 8 via a forward diode 14, and when the buffer amplifier 7 is reduced in the output, the diode 14 is brought to a reverse direction, and a CR delay circuit consisting of a shunt capacitor and a series resistance 16 is inserted between the two amplifiers 7 and 8 via a diode 17. This causes a device to operate in a prompt response when a fan is switched to a fast operation, and to actuate in a delayed response when switched to a slow operation mode. This prevents the occurrence of hunting of a relay, elongate a device life, improves safety, and permits the reduction of a switching noise.

Title: Read/write integrated circuit
Inventor: YOSHINAGA MAKI
IPC: G11B20/18
Filed: 1993-03-19
Abstract: PURPOSE:To speed up write operation by respectively providing the damping resistors of a magnetic head driving circuit between both ends of a magnetic head and a clamping part. CONSTITUTION:The damping resistor Rd is connected between the magnetic head 5 and a clamping circuit. In such a constitution, since the level of a magnetic head terminal is equal to that of the clamping circuit, a current ID flowing through the resistor Rd becomes nearly zero, and the head voltage of the magnetic head 5 is returned to a stationary level when the switching of the current is finished, and the current flows through the resistor Rd to suppress the overshoot. The voltage V is increased, and the resistor Rd is decreased since the unwanted current ID at the time of switching the current becomes nearly zero. In such a manner, the current shunted from the write current is formed by a transistor Q18, and the logical operation is performed with the shunted current and a mode switching signal formed by an OR gate circuit G3 by the transistor Q27, and a malfunction where the write current flows at a read mode time is detected.

Abstract: PURPOSE:To invariably set the cathode filament current within the allowable range during an operation by providing a thermal ferrite bead near a magnetron, and inserting a wire connecting a cathode filament driving coil and the magnetron into the thermal ferrite beam. CONSTITUTION:A high-voltage wire 11 connected to the anode of a magnetron MAG is inserted into a thermal ferrite bead FB, and the thermal ferrite bead FB is fitted to a yoke 2 radiating the heat of the magnetron MAG. When the temperature of the magnetron MAG is between the room temperature and the threshold value temperature of the thermal ferrite bead FB, the inductance of the thermal ferrite bead FB is given to the wire 11, the cathode filament current is limited immediately after the start of an operation, and no excessive current flows. When the temperature of the magnetron MAG exceeds the threshold value temperature, the inductance of the magnetron MAG becomes nearly zero, thus the cathode filament current is limited. The cathode filament current can be invariably set within the allowable range during the operation.
