Patent JP-H02274569-A (JP)
Title: Line printer
Inventor: TAMURA TOSHIYUKI
IPC: B41J2/45
Filed: 1989-04-17
Abstract: PURPOSE:To print a high-quality, multi-gradation picture by providing a photosensitive body with linear photosensitive characteristics and a light intensity altering means which controls the number of pluses input to a light emitting element according to each picture element density information shown by an input printing signal and which alters the light intensity of the light emitting element. CONSTITUTION:In an end-face light emitting type EL printer 11, the light emission of a line head 12 is controlled by controlling the synchronization of voltages applied to the line head 12 from matrix electrodes 16 and 17. In accordance with information on the density of a printing signal input by a data processing circuit 25, voltages applied from block electrodes 171 to 17n are pulse-modulated, and a voltage that hardly drops to a threshold voltage + or -E0 or below is applied to each end-face light emitting EL element. Then, the element flickers in a minimal time, and its light intensity halves, compared with when light is normally emitted. On the other hand, since the photosensitive characteristics of a photosensitive drum 14 are linear, the drum 14 is optically scanned by the head 12 whose light intensity varies stepwise. Consequently, toner attaching quantity is controlled to achieve almost stepless density gradation.

The paired legs 3 have their intermediate portions supported on a spring 6, and an electromagnetic vibration source 5 is fixed thereby to generate sine-wave vibrations in a unidirection to the right and left. For the paired legs 3, the diaphragm 4 is vibrated in the opposite phases in the direction of the side thereof. If the diaphragm 4 thus vibrating is inserted into a flowing fluid 10 or a sample to be measured, a laminar flow is established between the boundary of the diaphragm 4 and the fluid 10 so that the vibrations are damped in displacement in a manner to correspond to the flow friction. The vibratory displacement is detected by a piezoelectric receiving element 7 and is measured by an indicator 8.

Title: Image forming device using metal halide lamp
Inventor: TANAKA HIDEKI
IPC: G03G21/00
Filed: 1994-05-12
Abstract: PURPOSE:To prevent the generation of a large rush current, and suppress the generation of line conduction noise, specially normal mode noise, by controlling the timing of a switch connected between a metal halide lamp and a driving power source. CONSTITUTION:A resistor 8a and an inductor 8c are connected in parallel to the contact 5a of a second unipolar contact type electromagnetic switch 5, and timing is controlled so that the second unipolar contact type electromagnetic switch 5 is turned on upon the lapse of specified time after a first unipolar contact type electromagnetic switch is turned on at the closing time of a driving power source. Until the metal halide lamp is sufficiently warmed, a current flowing to the metal halide lamp 6 is suppressed by the resistance value of the resistor 8a and inductor 8c so as to prevent a large rush current from transiently flowing to the metal halide lamp 6. The rush current flowing into the metal halide lamp 6 can be thereby limited sufficiently while suppressing the generation of conduction noise associated with the switching of supply voltage with simple circuit constitution.

Namely, the character inputted from a keyboard 5 is KANA/KANJI converted by a main body 4, stored into a file 6 for a KANJI code and the HIRAGANA code of the reading of the same character string is stored into a file 7 for a HIRAGANA code. Next, when the prepared sentence is corrected, the HIRAGANA code is sent from the file 7 for HIRAGANA to a voice output part 8 and outputted by a voice from a speaker 3. Thus, the correction of the prepared sentence can be easily executed by both eye and ear.

Title: Transmitter-receiver
Inventor: ONODA TAKANORI
IPC: H04B1/50
Filed: 1987-04-23
Abstract: PURPOSE:To attain the transmission and reception over the desired entire communication frequency band by the transmitter-receiver of the same constitution by constituting a reception frequency conversion section so as to cancel an image frequency and providing a changeover means for the relation of upper/ lower state of a local signal frequency and a desired reception frequency. CONSTITUTION:A local signal outputted from a local oscillator 1 is inputted to mixers 3, 4 via a 0-90 deg. distributer 2. The signal at a reception input 9 is inputted to mixers 3, 4 in in-phase. Since the phase difference between the signal of the mixer 4 and the image signal and the desired reception signal of the mixer 3 is +90 deg. or -90 deg., the intermediate frequency signal extracted from the mixers 3, 4 is cancelled at a 0-90 deg. synthesizer 5 while bringing the phase of the image signal to be inverted to extract only the desired reception signal. Moreover, when the desired reception signal frequency is lower than the local signal frequency and the circuit is operated normally, a changeover switch 6 is switched to bring the desired reception frequency more than the local signal frequency to attain the operation.
