Title: Carriage scanning method in color ink jet recording apparatus
Inventor: FUKAZAWA TAKAO
IPC: B41J2/21
Filed: 1983-05-07
Abstract: PURPOSE:To shorten a time requiring from the detection of a deflection height to the start of printing, by performing the scanning for detecting a deflection amount in the order of black, cyan, magenta and yellow, and subsequently performing the ink draining of all heads simultaneously to make a drain position as a start position. CONSTITUTION:The home position of a carriage is set to the position to which a head for black is opposed to a deflection amount detecting electrode 2. By this positional setting, the deflection amount of a head K is at first detected and, subsequently, the deflection amount of a head C is performed by driving the drive motor of the carriage over the pitch of the head. Hereinafter, the detection of the deflection amounts of a head M and a head Y is similarily performed and draining treatment can be performed at the deflection amount detecting position of the head Y. By this mechanism, because draining treatment can be performed in a carriage holding state without returning the carriage after the derection of the deflection amount to the each head is performed, a time to the start of printing can be shortened.

Filed: 1987-04-01
Abstract: PURPOSE:To prevent production of nonlinear distortion by providing an external resistor between a source of an N-channel transistor (TR) among TRs composing an inverter circuit and the ground of an integrated circuit. CONSTITUTION:A filter 6 is connected to an output of a pulse width modulator converting a digital input signal into a pulse signal via an inverter circuit 5 being an integrated circuit 8 and an analog signal is obtained from an output of the filter 6.

Title: Superluminascent diode
Inventor: YAMADA ATSUSHI
IPC: H01L33/30
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To hold a hole injection efficiency so as to obtain a high luminous efficiency and high polarization quench ratio, by specifying the thickness of a barrier layer and no. of well layers in a multiple quantum well structure of an active layer. SOLUTION: A barrier layer 5 of a superluminescent diode SLD is set to 4 nm or less, without forming a strain in a well layer 4. If about 4 nm or less, the wave functions of the carriers esp. holes begin to couple with each other to thereby improve the uniformity of the carriers in the quantum well layer. The densities of electrons and holes in the SLD are higher than those of a semiconductor laser LD and hence either the no. or thickness of the well layers 4 must be increased. If the barrier layer 5 is 4 nm or less thick, increase of the layer no. never deteriorates the emission efficiency and hence the barrier layer 5 is set to 4 nm or less thick and the no. of the well layers 5 is set to 5 or more.

Title: Semiconductor storage device
IPC: H01L27/11
Filed: 1992-04-02
Abstract: PURPOSE:To provide a semiconductor storage device with a bit line load circuit that has a superior symmetric property in performance by arranging a pair of transistors such that parasitic resistances resulting from ion implantation occur in electrodes of the pair of transistors which are of the same circuit type. CONSTITUTION:If a current flows to a transistor T1 when a memory cell drive transistor is conducted, a voltage between a gate and a source of bit line load transistors T1 and T2 becomes either a potential between VDD and a bit line BL or between VDD and BLB. Hence, no difference due to a logic state of stored information arises in the amplitude of a signal to be inputted to the pair of bit lines BL and BLB. Therefore, the asymmetrical property of a circuit which is a problem in a conventional device becomes improved. For this reason, a sense amplifier, a bit line equalizer circuit or the like, and other circuits associated with a bit line become easy to design.

Filed: 1993-03-15
Abstract: PURPOSE:To obtain a sound solidified sample by forming a restricting part having small diameter opposing to a flow-in port and an enlarged part having large diameter opposing to a sampling chamber in an introduction pipe and controlling the flow-in speed of molten metal thereby preventing the molten metal from clogging a vent hole or overflowing. CONSTITUTION:A restricting part 21 having small diameter opposing to a flow-in opening 6 and an enlarged part 22 having large diameter opposing to the sampling chamber 8 of a sampler 4 are formed in an introduction pipe 5. Inner diameters (d) and D at the restricting part 21 and the enlarging part 22 are preferably set to satisfy a relationship; d/D=1/2-1/10. A probe body 1 is immersed into a molten metal injected through the opening 6. In this regard, flow rate of molten metal is limited at the restricting part 21 and the current velocity is lowered at the enlarged part 22. Current velocity is also lowered by bending the joint of the restricting part 21 and the enlarging part 22. Since jet or turbulence of molten metal does not clog a vent hole made at an upper part of the sampler 4 nor the molten metal flow over the vent hole, a sound solidified sample can be obtained.
