Title: Semiconductor laser
Inventor: ISHIGURO NAGATAKA
IPC: H01S5/00
Filed: 1989-06-16
Abstract: PURPOSE:To form a semiconductor laser in one epitaxial growth and to improve mass producibility by providing a striped optical guide layer adjacent to an active layer and by carrying out light confinement making an equivalent refractive index of the section high. CONSTITUTION:Four layers consisting of an N-type InGaAsP optical guide layer 2, an N-type InP clad layer 3, an InGaAsP active layer 4, and a P-type InP clad layer 5 are formed on an N-type InP substrate 1 whereto a striped mesa 6 is formed. The optical guide layer 2 is formed so that a thickness of an upper part of the mesa 6 is 0.1mum and the clad layer 3 is made thin on the upper part of the mesa 6 and thick on other regions. Therefore, when a thin optical guide layer is made adjacent to the active layer 4, an equivalent refractive index increases there, thereby forming a refractive index difference optical waveguide path having a high refractive index at the mesa section 6. If a zinc diffusion layer 8 is provided and a current is collected to the mesa section 6, a semiconductor laser having a light confinement mechanism at the mesa section 6 can be formed in one epitaxial growth and mass producibility improves.

Filed: 1977-12-24
Abstract: PURPOSE: To perform skip recording of the fields of video signal by reducing the running speed of a recording medium and making the maximum record-reproducible frequency 1/C of the maximum frequency of the audio signal processed.  
     CONSTITUTION: As compared to a standard case of straightly recording the continuous audio signal of 100%, the maximum record-reproducible frequency f rmax  is made 1/C of the maximum frequency f smax  of the audio signal processed by reducing the speed of a recording medium to convert the period of the audio signal C times, thus about 1/C of the audio signal at each segment is recorded. If the period of the audio signal to be reproduced is converted to 1/C times, the high density recording and reproducing of the audio signal become feasible. Such means is effective as the processing means of the audio signal of the case performing so-called skip recording wherein recording is performed by making the speed of the magnetic tape 1/n of the standard speed VN and 1 field is sampled out of the video signal of continuous (n) fields.

IPC: G09G3/294
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce required electric power consumption by driving a plasma display panel using a highly efficient drive wave form while regenerating electric power. SOLUTION: A switch SW4 is opened and a switch SW1 is closed at a time T2 to be charged to a panel capacitance CP1 . The switch SW1 is opened at a time T3 when a voltage of a terminal TP1 is one-half or more of a voltage of a connecting terminal TP2 and a VS or less. A switch SW3 is turned on from a time T4 when the voltage of the terminal TP1 comes to a holding voltage or more to a time T5 when returned to the holding voltage, a diode DD3 is made conductive, and the voltage of the terminal TP1 is clamped to the holding voltage. Although the switch SW3 is opened and the SW2 is closed at a time T6 , the switch SW2 is opened before a time T7 because electric power is spent wastefully by a current owing to electromotive force, and energy of a coil L1 is recovered into a capacitor CP2 .  The diode DD3 is connected to the switch SW3 in series to generate a holding pulse voltage wave form for overshoot while functioning an electric power regenerating circuit.
