Patent JP-H06268320-A (JP)
Title: Semiconductor laser device
Inventor: SUZUKI NOBUO
IPC: H01S5/00
Filed: 1993-03-12
Abstract: PURPOSE:To cause a significant variation of wavelength in a short time by raising the temperature of an active layer using heat generated therein. CONSTITUTION:Excess voltage is applied to an undoped InAlAs barrier layer 28 in order to lower the barrier for electrons thus injecting high energy electrons into an undoped InGaAsP lower optical guide layer 22, a strained quantum well structure active layer 25, an undoped InGaAsP upper optical guide layer 26, and an undoped InP layer 27. Since electrons are converted immediately into thermal energy through relaxation, temperature rise begins at early time. When the current is varied to obtain a final oscillation wavelength identical to conventional one, feedback control can be facilitated but the settling time of oscillation wavelength is not shortened so much. In order to shorten the settling time, excess current is fed until the oscillation wavelength reaches a predetermined value close to a desired value and the current is decreased to 2 predetermined settled value at a moment when the oscillation wavelength reaches the predetermined value.

Title: Ink jet recording device
Inventor: MINEMOTO HITOSHI
IPC: B41J2/06
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent spontaneous ink discharge from occurring and stabilize an image quality by controlling a voltage applied to an electrophoretic electrode which concentrates a coloring material particle contained in a pigment ink into an ink discharge aperture with the help of a voltage control means. SOLUTION: A voltage applied to an electrophoretic electrode 3 is changed stepwise so that a meniscus deformation time constant is constantly less than a pigment ink time constant. That is, a coloring material particle of the pigment ink 10 contained in an ink chamber 1 moves to an ink discharge aperture 2 by applying a constant voltage to the electrophoretic electrode 3 to add an electric field to the ink chamber 1. A meniscus tends to deform but the surface of the pigment ink 10 is equilibrated to stop the coloring material particle. Next, the meniscus forms gradually by applying higher voltage than the constant voltage as described. After that, the meniscus deforms by applying a voltage in tended for the purpose and meniscus is formed on the tip of a discharge electrode 5.  In this case, a pulse discharge voltage is applied to the discharge electrode 5 and consequently, the coloring material particle sticks to a recording medium 4 after developing into a jetted particle group 11.

IPC: G06F3/02
Filed: 1987-03-11
Abstract: PURPOSE:To trace the information on key operations via a keyboard unit only by writing successively the produced code data into a memory means and then reading this data with indication of a read mode for display. CONSTITUTION:A changeover switch is usually kept turned off and a CPU 1 scans a key matrix 2. When a key is pushed, the same data as that on the pushed key is written into a RAM 11. Thus the data equal to that which is transferred to a work station from a keyboard unit is successively written into the RAM 11. If the abnormality occurs, an operator turns on a switch 13. Then the data of a single unit is read out of the RAM 11 every time a specific key is pushed. An LED 8 is turned on in accordance with the data read out of the RAM 11. In such a way, the information on the produced abnormality is read out and displayed with simple key operations.
