Title: Method for replenishing ink to ink cartridge and apparatus for replenishing ink used in the method
Inventor: SAKUMA TADASHI
IPC: B41J2/175
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from entering an ink cartridge when ink is replenished and prevent ink from leaking from a printing head part. SOLUTION: According to this method, an ink 7 is replenished to an empty ink cartridge having an ink feed port to a printing head part or printing head with the use of an ink replenishment device filled with the replenishment ink 7. An ink replenishment hole 3 is formed in a main body 2 of the ink cartridge. After the ink feed port to the printing head part or printing head is shut, a nozzle part 6 of the replenishment device is inserted to the ink replenishment hole 3, thereby to tightly seal the ink replenishment hole 3 by the nozzle part 6. In this state, a pressure is added and reduced to the ink 7 in the replenishment device alternately repeatedly, whereby the ink 7 is replenished into the main body 2.

Inventor: SAKUTA TOSHIYUKI
IPC: G11C11/401
Filed: 1991-01-11
Abstract: PURPOSE:To improve the efficiency of using remedy bit in remedy line and to reduce the occupied area of remedy line by replacing bit-related defect concerning a word line or a data line with a common remedy line by the unit of bit. CONSTITUTION:By a discriminating circuit 23, the stored information of X address, Y address and an address register 26 for remedying bit are compared, and when they are coincident, a remedy signal is asserted. When the remedy signal outputted from a discriminating circuit 23 is asserted, a normal word line which follows an input address is selected in an address multiplex system, and then the remedy data line, which is specified by the input address and the remedy signal, is selected. Also, in a non-address multiplex system, for both the word line and the data line, the remedy word line and the remedy data line, which correspond to the input address and the remedy signal, are selected. In either system, bit-related defect is consequentially replaced with the common remedy line by the unit of bit, and the bit-related defect is remedied.

Title: Antenna element for portable communication terminal
Inventor: SUGIMURA SHIRO
IPC: H01Q1/24
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To suppress the external dimension of an antenna element to a minimum and to enable addition to the case of a portable communication terminal in good appearance by providing a 1nd conductor, with which one terminal of 1st conductor is successively linked to the other terminal, and forming these 1st and 2nd conductors through a substrate onto a coil. SOLUTION: An antenna element 10 for a portable communication terminal is provided with a substrate 11, 1st conductor 21 and 2nd conductor 22 to be arranged on the substrate 11. The 1st conductors 21 are parallelly arranged at the interval of a prescribed pitch d1 on the surface of the substrate 11. The 2nd conductor 22 successively links one terminal of each 1st conductor 21 to the other terminal respectively through holes 23 at both terminals. Therefore, the 1st and 2nd conductors 21 and 22 forms a coil 20 having length d2 and width d3 as a whole through the substrate 11. Thus, since the 1st and 2nd conductors 21 and 22 can form the coil 20 through the substrate 11, the external dimension can be minimized as a whole and the addition to the case of a portable communication terminal is enabled in extremely good appearance.

Title: Optical head
Inventor: YASUKAWA KAORU
IPC: G11B7/135
Filed: 1988-01-07
Abstract: PURPOSE:To accurately perform recording, reproduction, and erasure by fixing collimator lenses on lens barrels provided integrally with a substrate so as to enclose the peripheries of two semiconductor lasers, respectively. CONSTITUTION:The lens barrels 31 and 32 of the collimator lenses 11 and 21 are mounted directly on the substrate 30 which fixes the n semiconductor lasers 1 and 2. In other words, the collimator lenses 11 and 21 which collimate the laser beams are structure in such a way that they are not operated independently for the semiconductor lasers 1 and 2. Therefore, when expansion or compression due to the temperature is generated in the same substrate 30 on which the semiconductor lasers 1 and 2 are mounted, the quantities of travel of the two semiconductor lasers 1 and 2 become almost equal to that of the lens barrels 31 and 32 on which the collimator lenses 11 and 21 to collimate the semiconductor lasers 1 and 2 are mounted. In such a way, it is possible to always keep parallelism between two emitting laser beams, and to perform the recording, the reproduction, and the erasure accurately.

Title: Protective circuit of mos semiconductor device of one conductivity type
Inventor: YAMANE KATSUTOSHI
IPC: H01L21/8234
Filed: 1990-01-08
Abstract: PURPOSE:To protect an internal circuit from static electricity by a method wherein a source and a drain of a MOS transistor is connected respectively between an input terminal of a circuit to be protected and power-supply terminals on the side of a high voltage and on the side of a low voltage. CONSTITUTION:When negative static electricity is applied to an input terminal by using a power-supply Vcc terminal as a reference, it is biased in the direction of a diode 4 which is parasitic on a protective resistance 3. A P-electrode of the diode 4, i.e., an Si substrate, is common to a P-electrode of a diode 5 annexed to the power-supply Vcc terminal. The negative static electricity applied to the input terminal is passed through the protective resistance 3 and the diode 4, and biases the diode 5 in the reverse direction. Since a MOSTr 8 is inserted in parallel with the diode 5, the Tr 8 is punched through before the diode 5 is broken down; the static electricity is discharged to the power supply Vcc terminal used as the application reference. On the other hand, when negative static electricity is applied by using a GND terminal as a reference, a diode 6 is biased in the reverse direction. However, it is possible to prevent the diode 6 from being broken down because a Tr 9 is punched through.

IPC: H04L7/02
Filed: 1981-01-13
Abstract: PURPOSE:To obtain data possibly precise until a phase locked loop is surely synchronized, by switching to a clock reversed in phase to a present regenerated clock when there is phase slip, and by using it as a lock for regeneration. CONSTITUTION:The output of a clock synchronizing circuit 4 is sent to a clock selecting circuit 5 to extract an output clock or its inverted clock (c) selectively, and the clock is sent to an output terminal 3. When there is a phase slip and the digit of digital input data right after it has a ''1'', the output of the FF63 of a phase slip detecting circuit 6 is inverted and at its Q' output terminal, an output (g) with the ''1'' showing the detection of the phase slip appears. A change in the signal inverts the output of the FF71 of a clock selection-signal generating circuit 7 and an output (h) from the output terminal Q goes up to the ''1'' while the output (i) from the terminal Q' is inverted to a ''0''. Consequently, the AND circuit 53 of the circuit 5 is closed and an AND circuit 52 is opened to obtain a clock (c), obtained by inverting the output clock (b) of the circuit 4, as a regenerated clock.
