IPC: H01F21/06
Filed: 1984-01-06
Abstract: PURPOSE:To enhance adjusting accuracy of inductance and improve reliability after adjustment by sealing elastic resin at the lower side of core within a bobbin at a variable inductor of core rotating type. CONSTITUTION:A bobbin 1 made of non-magnetic material of which external circumference is wound by a winding 3 is housed in a case 4 and a pair of leads connected to the winding 3 are connected respectively to a pair of terminals 5 protruded to the outside of case 4. Along the threaded groove provided to the internal circumference of bobbin 1, a core 2 made of ferrite is threaded. In this case, an elastic resin 7 is sealed at the lower side of core 2. The core 2 is pushed in the direction (d) using an adjusting rod 8 until it is balanced with a force in the upward direction (e) generated on the resin 7. When the specified inductance is obtained, the internal layer of bobbin 1 and the upper end part of core 2 are fixed using the quick dry type bonding agent 9 for fixing the core.

Title: Facsimile transmitter
Inventor: TAKAHASHI ETSUROU
IPC: H04N1/32
Filed: 1982-01-06
Abstract: PURPOSE:To print transmission sequential number and the total on a received picture automatically, by presetting the total of transmitted originals. CONSTITUTION:When the operator inputs the total number of originals from an control input section 10 ahead the transmission of original, the number is coded at a code conversion section 11 and stored in a storage section 12. The original is read at a reading section 1 and transmitted to a line via a buffer memory 2, an encoding section 3 and a modulation section 4. A counter 9 is set to 1 at first and counts signals from a detection section 7 at each end of transmission of one original. This count value is stored in the storage section 12 via the conversion section 11. A control section 8 detects a prescribed position of the transmitted original at main and sub-scanning timing generating sections 6 and 14, reads out the numeral of the counter 9 representing the transmission serial number and the total, generates a character pattern at a character pattern generator 13 and transmits the pattern to the reception side.

Filed: 1985-01-08
Abstract: PURPOSE:To observe a finder image well by changing the shape of the visual field frame of a finder in accordance with varying of magnification to reduce a sense of incompatibility on observation which is caused by the distortion of the finder image due to the variance of the distortion of the variable power finder. CONSTITUTION:The visual field frame on a frame 6 is so constituted that two, barrel-shaped and bobbin-shaped pattern parts formed with dot patterns consisting of a liquid crystal, an electrochromic element, or the like are put on the frame 6. The variable power state of a variable power lens 9 is detected by a variable power position detecting means 7, and the electrochromic element or the liquid crystal is operated by a known control method to change the shape of the visual field frame between barrel-shaped and bobbin-shaped patterns. That is, the shape of the visual field frame is changed to the barrel shape if the distortion of the variable power finder lacks compensation in the wide angle side in accordance with varying of magnification, and the shape of the visual field frame is changed to the bobbin shape if this distortion is compensated excessively in the telephoto side.

Filed: 1991-01-10
Abstract: PURPOSE:To increase luminosity on the side of a radiation opening face of a fluorescent lamp mounted on an equipment main body without performing special processing on the fluorescent lamp. CONSTITUTION:A fluorescent lamp 4 is mounted facing the radiation opening face 2 of an equipment main body 1. An electromagnet 7 to be excited synchronizing with lighting frequency of the fluorescent lamp 4 is mounted on the equipment main body. The electromagnet 7 generates an alternating magnetic field displacing an arc of the fluorescent lamp 4 always on the side of the radiation opening face 2 of the fluorescent lamp 4 by Lorentz's force. When the arc displaced on the side of the radiation opening face 2 of the fluorescent lamp 4, an amount of ultraviolet rays incident on a phosphor film 6 on the side of the radiation opening face 2 of the fluorescent lamp 4 increases so as to increase luminosity on the side of the radiation opening face 2 of the fluorescent lamp 4.

Title: Ink jet recording head
Inventor: MORIYAMA JIRO
IPC: B41J2/045
Filed: 1986-01-09
Abstract: PURPOSE:To improve recording speed significantly by providing a means to prevent a backflow of ink into a nozzle of an ink jet recording head. CONSTITUTION:A value 4 is provided at on outlet to an ink chamber 1 in an ink supply channel 3 of a recording head. When a drive signal is applied, a piezoelectric element 5 is transformed to the ink chamber 1 side and thereby ink droplets 7 are discharged through an orifice at the tip of a nozzle 2. At that time, the valve 4 closes preventing a backflow of ink to the ink supply channel 3 side. When the piezoelectric element 5 is returned to its original position, the valve 4 is opened allowing ink to be supplied into the ink chamber 1 from the ink supply channel 3. Thus a one-way flow through the ink supply channel is insured, and the restoration of a meniscus 8 of ink generated in the orifice at the tip of the nozzle 2 can be accelerated. Consequently recording speed can be significantly improved.

Title: Drive method and ink jet printing head
Inventor: SARUTA TOSHIHISA
IPC: B41J2/045
Filed: 1993-01-08
Abstract: PURPOSE:To realize a low-cost drive circuit by providing a transistor, which is connected to an electrode opposed to an electrode for connecting a capacity load to a drive signal generation means, and a control means for applying a voltage to a gate of the transistor. CONSTITUTION:A voltage value of a drive signal is applied to a capacity load 2. A voltage of a threshold or higher is applied to a gate electrode 12 of a transistor 3 from a control circuit 4. At this time, a voltage (VDS) between a drain electrode 13 and a grounded source electrode 11 is zero. Thus, a current (IDS) does not pass between the drain electrode 13 and the grounded source electrode 11. With the linear increase of the drive voltage, the VDS is increased. The current IDS is passed by transistor IDS-VDS characteristics. A voltage is applied between electrodes of the capacity load 2 to pass a charging current ICR. The ICR is a fixed current having a rectangular current waveform. A current equal to the ICR is passed between the drain and source electrodes of the transistor 3. A voltage value for the ICR is found by the characteristics of the transistor 3. A voltage waveform to be applied to capacity load 2 is found by subtracting a voltage waveform corresponding to the ICR from the waveform of the drive voltage.

Abstract: PURPOSE:To attain binarization with more fidelity to an original picture by changing a binarized error quantity in response to the result of binarization of a picture element already binarized adjacent to a picture element of interest while taking the effect of erosion of an ON picture element onto an OFF picture element into account. CONSTITUTION:A binarization means 101 binarizes data into either of a gradation corresponding to dot ON and a gradation corresponding to dot OFF. A binarization error calculating means 102 determines the quantization error generated by the binarization. An error quantity optimizing means 103 checks whether the result of binarization is ON or OFF, references adjacent already binarized pixel information 104 in the case of OFF and applies the correction taking the influence of protrusion of dots from the adjacent already binarized picture element into account to the dots. When the calculation of a binarization error is finished, an error spreading means 105 distributes the obtained binarization error to an un-binarized picture element in the vicinity.
